Frequently Asked Questions

About our products

Are your products easy to install?

No. We manufacture industry leading specialist products; therefore, we would never recommend a DIY installation.

We do offer a Supply Only Service where the products come complete with a fitting instruction manual. These instructions ensure that installation by a skilled tradesman is possible, however, if they are unsure of the term ‘toe and heeled’ or have little to no experience with fitting aluminium products we highly recommend allowing our fitters to install your doors – this also means longer and more comprehensive guarantees.

Are all of your products bespoke?

Yes, every door, window or roof system we manufacture is made to suit client and site specific requirements. We do not offer any standard size products as it is much simpler for us to cut aluminium profile than it is for architects and builders to work around a set size, and as our lead times are so short your project won’t be held up.

Whilst there are some slight restrictions on systems due to glass weights, everything we do is tailored to you.

WHAT IS THE MAXIMUM HEIGHT FOR YOUR BI FOLDING DOORS?

The XP View can be manufactured up to 3000mm high, and our XP10 system can go up to 2400mm.

HOW MANY PANELS SHOULD BE IN MY BI FOLDING DOORS?

Although the XPView can go slightly larger, the general rule of thumb is that the largest panels should be 1000mm wide. We always recommend the minimum amount of panels possible within a run of bi-folding doors as this improves the overall aesthetic of the door due to maximising the glazed area. This is also a more cost-effective option as the additional components in each panel does have a heavy impact on the overall price.

HOW MANY PANELS SHOULD BE IN MY SLIDING DOORS?

We strongly recommend the minimum panels possible; this then creates large glass areas which can slide aside – they can be made in 2, 3, 4 6 or even 8 panel set ups capable of spanning extremely large spaces.

WHAT IS THE MAXIMUM HEIGHT FOR YOUR SLIDING DOORS?

The maximum height of our XP Glide sliding doors is 2550mm, 2700mm for the XP Glide R and 3000mm for the XP Glide S – the slide panoramic is our most restricted at 2500mm.
WHAT GUARANTEES DO YOU OFFER?

ARE THE DOORS TOP OR BOTTOM HUNG?

All our products (sliding doors, or bi-folding doors) are bottom running meaning there is no weight in the head of the doors.

The doors being bottom hung is of great benefit because the doors themselves will not cause any deflection in the steel above, nor will they snag at the slightest deflection in any steels as is the case with top hung systems.

CAN I HAVE A COMPLETELY LEVEL THRESHOLD TO MY PATIO?

All our systems allow for a flush finish to internal floors, meaning no step up to get out to your garden / patio.

Our sliding systems can allow a completely flush finish between internal and external floors (providing adequate drainage is in place) to ensure bi-folding doors are weather tight, a small rebated upstand from the internal to the external is recommended to guarantee years of trouble free use.

Materials

How energy efficient are your windows and doors?

All of our products are very thermally efficient; they meet and exceed all current and planned future building regulations.

All our products are thermally broken and benefit from high performance double glazing with a U Value of 1.1 as standard. The maximum overall U value of any of our products is 1.6 and 1.5 in our windows, with many of our door and window products boasting even lower U values.

WHAT’S THE DIFFERENCE BETWEEN PVC BI FOLDING DOORS AND ALUMINIUM BI FOLDING DOORS?

Aluminium bi-folding doors are:

- Better looking
- Smoother to operate
- More reliable
- More durable
- Extremely secure
- Thermally broken, giving high performance European weather ratings

UPVC folding doors are less secure and much more prone to failures such as jamming, especially on larger door systems and they offer no comparable weather ratings.

Aluminium is much slimmer and stronger than UPVC, it also doesn’t expand and contract in the heat and cold like plastic products do.

IS THE COATING SUITABLE FOR A MARINE ENVIRONMENT?

Yes, our aluminium products are powder coated which is typically commercial application guaranteed for 25 years. Installed at a location within five kilometres from the sea this will reduce to around ten years but a specific guarantee can be given dependent on the site location.

In a marine environment, such as a home on the coast, the salt in the air can corrode the powder coating. To alleviate this, we ‘marine grade’ the powder coating which is a slightly different grade of coating and we also treat all corners, joints, and mitres during manufacture to prevent any corrosion, this coating and treatment guarantees the coating even in the harshest coastal environment.

Customisation

Can I choose the colour of finish of the doors?

The handles are standard on each door and window system, but they all have a range of colour options visible in our showrooms.

Our hinges and gaskets used are always made in black, regardless of frame colour due to the quality of material of gasket.

ARE ALL YOUR PRODUCTS BESPOKE?

Yes, every door, window or roof system we manufacture is made to suit client and site specific requirements. We do not offer any standard size products as it is much simpler for us to cut aluminium profile than it is for architects and builders to work around a set size, and as our lead times are so short your project won’t be held up.

Whilst there are some slight restrictions on systems due to glass weights, everything we do is tailored to you.

CAN I HAVE A COMPLETELY LEVEL THRESHOLD OUT TO MY PATIO?

All our systems allow for a flush finish to internal floors, meaning no step up to get out to your garden / patio.

Our sliding systems can allow a completely flush finish between internal and external floors (providing adequate drainage is in place) to ensure bi-folding doors are weather tight, a small rebated upstand from the internal to the external is recommended to guarantee years of trouble free use.

CAN I CHOOSE MY FINISHINGS SUCH AS DOOR HANDLES OR ARE THEY STANDARD?

The handles are standard on each door and window system, but they all have a range of colour options visible in our showrooms.

Our hinges and gaskets used are always made in black, regardless of frame colour due to the quality of material of gasket.

THE PROCESS

WHEN SHOULD I LOOK TO INVOLVE EXPRESS IN OUR PROJECT?

Generally, the earlier the better!
As manufacturers of high quality glazed products we can offer advice on what solutions are available from our own product portfolio to suit various design ideas, at any point in a project. This allows you to incorporate the best products to suit your design right from the very beginning.

Our services do not extend to architectural design of properties or construction work, so whilst we can happily provide options for our own products, the final building’s design, planning permission, and building regulations drawings will need to be completed by an architect.

AT WHAT STAGE DO I NEED A SITE SURVEY?

In order for us to carry out a site survey ideally your openings will need the steel/RSJ in place and your finished floor level will need to be clearly marked. This will allow us to carry out your site survey as we will know exactly what to measure to. It is possible to carry out a survey without the opening being ready however the manufacturing sizes will need to be agreed and signed off before manufacture takes place.

WHAT ARE YOUR CURRENT LEAD TIMES?

Our lead times fluctuate throughout the year. Our company ethos is to manufacture and install/deliver all of our products as quickly as possible.

Because all manufacturing takes place in-house we control all aspects of your project so even in our busiest times we will always have your works complete within weeks and not months.

Our sales staff can always advise accurately at the point of order what our lead time is likely to be on your project.

DO YOU SUB CONTRACT ANY OF YOUR WORK?

No, all of our staff are employed by Express Bi-folding Doors; this is why we can always assure you of a job well done. Our surveyors and installers are experts in their field and take great care throughout all of their works. It is this reason why we can offer unbeatable warranties, it also means we take full responsibility for all aspects of our works and you won’t ever be stuck in the middle of an argument between a sub-contractor and the manufacturer as is the case with many of our competitors.

WILL YOU RIP OUT AND TAKE AWAY MY EXISTING DOORS AND WINDOWS IF REPLACING THEM WITH YOUR PRODUCTS?

Yes, we are happy to take on all works, including small building works for an extra fee – to ensure we can quote this accurately please provide our sales team with imaging of what needs to be taken away.

If we’re removing products we will also issue a certificate from Certass offering a 10-year insurance backed guarantee on our work.

THE COMPANY

DO YOU COVER THE WHOLE OF THE UK?

We service the whole of mainland UK. We are happy to undertake installations anywhere within mainland England, Scotland or Wales.

Any overseas projects we are happy to deliver to mainland UK ports, but unfortunately cannot cater for the shipping of goods.

WHAT GUARANTEES DO YOU OFFER?

All of our products come complete with a comprehensive warranty. We offer a full five-year warranty on all integral blind products and a full ten years on our doors, windows, roofing systems and double glazed units. Our powder coating aluminium benefits from a 25-year warranty (ten years in locations next to the sea).

Unlike many of our competitors, our warranties are comprehensive with no disclaimers in the small print, if we install your products we fully guarantee for years meaning you benefit from our unparalleled after sales service.

If a job is done on a supply-only basis, Express still guarantee the manufacture of the products, however cannot guarantee the quality of a third party’s installation work, meaning if anything hasn’t quite gone how you would like it we can come out to asses a third party’s work for a small charge – but if you’re having an issue your first point of contact should be the person who installed the doors/windows.

DO YOU SUB CONTRACT ANY OF YOUR WORK?

No, all of our staff are employed by Express Bi-folding Doors; this is why we can always assure you of a job well done. Our surveyors and installers are experts in their field and take great care throughout all of their works.

No, all our staff are employed by Express Bi-folding Doors; therefore, our work is always to the highest standard. Our surveyors and installers are experts in their field and take great care throughout all their works. It is this reason why we can offer unbeatable warranties, it also means we take full responsibility for all aspects of our works and you won’t ever be stuck in the middle of an argument between a sub-contractor and the manufacturer as is the case with many of our competitors.

Do you do standard sizes?

No, all the products that we manufacture are completely bespoke to your requirements.

How long will it take for a quotation to come through?

Not long, we always endeavour to respond to our customers as quickly as possible. We always aim to send quotes to our clients the next working day as a rule and to respond to large scale plans within seven working days.

Can I send my plans for you to quote from?

Of course, we often correspond with clients for a considerable length of time going back and forth as plans change and we will also offer our recommendations and expertise if we think we can add value to your project or specific elements of your plans.

My architect and builder will be looking after the job, can you deal with them on my behalf?

Yes, we regularly work with and liaise with our client’s architects, builders, designers and project managers. It’s not uncommon for industry professionals to visit our showrooms on behalf of their clients, we welcome this as it helps to ensure that all parties are singing from the same hymn sheet with the client and the end-result everyone’s main-focus.

Can I bring plans in to go through with someone in one of your showrooms?

Yes, we have an experienced and consultative sales team, so our experts will be able to talk through your plans and outline which products will be most suited to your requirements.

To what standard are the locks you fit, are they British Standard?

As part of our commitment to industry leading quality we offer high security, anti-snap, anti-drill, anti-pick and anti-bump lock cylinders as standard throughout our entire range of doors. These premium lock barrels are 3-star diamond rated BSI cylinders which reaches Secured by Design accreditation. We even supply these cylinders in doors with a half a barrel so internally the lock cylinder boasts all the same security benefits meaning that if an intruder does get into a property they will not be able to break-out through our doors.
Unlike other Secured by Design standard lock barrels, the keys for the barrels supplied by Express can be cut at any locksmith without the need for a specific lock card to have further keys cut. The lock barrels themselves are supplied by one of the worlds’ leading manufacturers of lock cylinders, which we think is the perfect complement to our industry leading range of products.

Are you Secured by Design Accredited?

Yes, we have several products which are certified Secured by Design and recommended by the police as products that reduce crime. We can offer bi-folding doors, sliding doors, windows and front doors that meet this specification, so our sales team can talk through these options with you.

Are your doors top or bottom hung?

All our products (sliding doors, or bi-folding doors) are bottom running meaning there is no weight in the head of the doors.

The doors being bottom hung is of great benefit because the doors themselves will not cause any deflection in the steel above, nor will they snag at the slightest deflection in any steels as is the case with top hung systems.

How energy efficient are your doors and windows?

All our products are very thermally efficient; they meet and exceed all current and planned future building regulations. All our products are thermally broken and benefit from high performance double glazing with a U Value of 1.1 as standard. The maximum overall U value of any of our products is 1.6 and 1.5 in our windows, with many of our door and window products boasting even lower U values.

Is a Bi-Folding door or a Sliding Door better suited to my property?

Both are great products, and both come with the same comprehensive guarantee. All our products have their own key features and benefits, so we’d always recommend seeing the products first hand before making up your mind. All our showrooms have all our products installed into real home settings which gives visitors a very real flavour of how they’ll look and work in their own home and it is examining all the products in this setting which really lets our customers know which product is right for them.

Can I have blinds for my roof lantern?

Not internal blinds no. We can pass on the contact information of a company who offers horizontal zip blinds that work well under our lanterns.

Are the blinds black out blinds?

No, the benefits of the integral blinds we offer are light control, shading and privacy but they don’t offer total black-out.

Can I have blinds in sliding doors?

In our sliding doors that are not structurally bonded yes. There are size limitations and certain configurations where the blinds cannot be operated so our sales consultants can advise which products can and can’t have integral blinds.

I live near the coast; can I have aluminium doors and windows?

Yes, we can manufacture our products with marine grade powder quality and we pre-treat all joints and mitres prior to manufacturing the products. Typically, our powder coating guarantee is ten years but in coastal environments we will give a specific guarantee based on the site location and exposure, this specific guarantee will be for a minimum of five years if not more but will be subject to correct and regular maintenance.

Maximum height for your doors?

We have varied height limits depending on the door product in question but while we recommend tall doors because they look slimmer and allow in more light we do advise that 2700m is about tall as we’d recommend. We can manufacture and install doors up to three metres high but that is our ceiling – literally.

What are your current lead times?

Our lead times fluctuate throughout the year. Our company ethos is to manufacture and install/deliver our products as quickly as possible. Because all manufacturing takes place in-house we control all aspects of your project so even in our busiest times we will always have your works complete within weeks and not months. Our sales staff can always advise accurately at the point of order what our lead time is likely to be on your project.

Will you rip out and take away my existing doors and windows if replacing them with your products?

Yes, we are happy to take on all works, including small building works for an extra fee – to ensure we can quote this accurately please provide our sales team with imaging of what needs to be taken away. If we’re removing products we will also issue a certificate from Certass offering a 10-year insurance backed guarantee on our work.

Do you offer an insurance backed guarantee?

Yes, when we install our products we offer a ten-year insurance backed guarantee alongside our own comprehensive ten-year guarantee.

SURVEYS

At what stage do I need a survey?

For us to carry out a site survey ideally your openings will need the steel/RSJ in place and your finished floor level will need to be clearly marked. This will allow us to carry out your site survey as we will know exactly what to measure to. It is possible to carry out a survey without the opening being ready however the manufacturing sizes will need to be agreed and signed off before manufacture takes place.

Do I have to be there at time of survey?

We do always recommend that the client should attend the survey as that is a key stage in the project where we finalise the order prior to manufacture. We understand this isn’t always possible, so we can meet with a site operative and then confirm all the specifications over the phone or by e-mail after the survey has taken place.

How long will the survey take?

This varies depending on the size of the job and the state of the site. Typically, our surveyors will be on site for at least an hour, but on large jobs they could take all day and then draw the project up off-site which will then be e-mailed over to discuss, check and sign off prior to manufacture.

Will the survey be booked for a specific time and date?

Yes, we have several fulltime project surveyors, so we will be as flexible as we can, but we will offer a specific date and as specific a time as we can. As we cover the whole of the UK the slots will be between 9-10:30 for example, we can ring en-route to advise an accurate time if required.

Will you liaise with my builder/architect in preparation for the site to be ready for survey?’

Yes, we will need the site to be a certain stage before we can survey it properly so we’re happy to speak to your teams on site to ensure that when we arrive we can survey the project with no unnecessary delays.

I have a question regarding my survey, who should I contact?

We have a team who arrange our surveys, so they may already be in contact with you or you can ring the survey department on 0345 340 9317. In most cases though the easiest option is to go straight to your sales consultant as they’ll be familiar with the job and the project.

Can you agree sizes if the opening is not formed?

Yes, but this isn’t a straight forward agreement, so we’ll still need a site meeting with your builder and ideally you as well. We will need to know exactly where the finished floor level will be to ensure there’s no unnecessary up-stand and your builder must be 100% confident to manufacture the opening to the agreements made and signed up with our surveyor. When we survey a job, we take full responsibility for the sizes, if the sizes are agreed the onus falls heavily upon your builder so he must be confident and happy to accept this responsibility.

PRIOR TO INSTALLATION

I have a query with my invoice, what do I need to do?

Your sales consultant will be able to explain your invoice if you have any questions, alternatively you can ring our accounts department on 0345 340 9313

Can you install whilst my scaffolding is in place?

For us to install your products we need a clear opening space to be able to successfully install the doors and commission them to our high standard. This means no scaffolding or any other interferences around the area of install. This will have to be cleared or moved prior to our arrival on site to ensure a swift, safe and stress-free installation.

Can I put my floor down before installation?

Although this is not recommended, in some instances where you have a larger scale floor to cover it’s hard to avoid! We advise that with all smaller builds the flooring be put down after the installation of the doors for obvious reasons. Once the glazing is in your build will then be wind and water tight allowing you to continue with the finished details like internal plaster, insulation and electric works along with the flooring you have chosen to install. In circumstances where flooring is a large part of the project you can begin the process but will be advised that you leave an area around the opening for the doors unfinished to ensure perfect finishes and protection of your new flooring. Our installation teams are clean, efficient and courteous to what is around them and are aware of protecting areas of property when required – this can all be requested at point of survey or point of install and we will be happy to assist.

Can I render/plaster my extension before the installation?

No, we always recommend installing our products first and then you can render/plaster up to the products once they’re in to achieve a proper quality finish. We have had projects before where clients have plastered internally but left the reveals where our products are going, this is fine but as the space isn’t watertight until our products are installed it is best practice to do all plastering once the products are in.

There are parking restrictions at my property, what do I need to do?

You need to arrange for adequate parking for our surveyors and installation teams as it is not our responsibility to arrange for parking. We will either need a space left for our vehicle(s) or you will need to provide a permit for as long as we require on site.

INSTALLATION

Do I have to be present at time of installation?

No but it is beneficial to all parties if you are there at completion to check that you’re happy with everything and to be shown how to operate the products correctly and do a complete sign off and handover. At this stage you will then receive our operation and maintenance pack also.

Can you leave any protective tape on my doors/windows?

Yes, but we’ll need someone to inspect the goods and sign off that they’re not damaged prior to the protective tape being put on. We’ll also advise how long the tape can stay on for because in the Summer months the tape can melt onto the profile if left on for months.

POST INSTALLATION

Do you provide maintenance instructions?

Yes, we provide full maintenance and operation instructions with supporting photography.

What do I do if I have a problem with my installation?

If your installation is on-going you’ll have a designated contact who’ll be regularly in contact with you but once your installation is complete just e-mail aftersales@expressbifolds.co.uk with your job number and a brief description of the problem and we’ll be in touch as soon as possible.

If I move to a new house can I transfer the guarantee to someone else?

Yes, but the guarantee is not freely transferable. Because our guarantee is comprehensive for ten years we charge £350+VAT to transfer the guarantee but as part of this service we attend site to fully service the doors, show how to operate them and hand over the maintenance and operation pack.

Can I extend my warranty?

Our guarantee period is comprehensive for ten years. Subject to correct use and care the lifespan of the products can easily exceed the guarantee duration so we can still resolve any issues with the products, but these will be subject to a call-out charge.

How can I protect my frames?

It is important that trades on site take care when working in and around our products. The bottom tracks need to be cleaned and kept clear of debris and protective tape should be placed over them if trades are working within their vicinity. Post installation you will receive a complete maintenance pack which advises on how to clean and maintain them.

What is covered by my guarantee?

With our full installation service, you will receive a comprehensive guarantee as part of your purchase. This means your powder coating, all mechanisms and moving parts, our labour and glass is all fully guaranteed for 10 years. Installations in coastal locations are subject to specific powder coating guarantee which is given based on the site post-code. Integral blinds come with a 5-year manufacturers guarantee.
Any issue no matter how slight will be deal with professionally by our after-sales department who will arrange a site visit by one of our skilled engineers to resolve any issues with our installation or products.
