10 Essential Questions to Ask Your Bifold Door Installers
Lifestyle
Bifold doors make a fantastic long-term investment, redefining the look and value of your property. However, with so many options and installers to choose from, it can be hard to find the right team for your project.
To help guide you, we spoke with our Managing Director, Steve Bromberg, who shared his top questions to ask any installer before committing. These questions will not only help you understand what’s included in each quote but also ensure you receive a high-quality installation backed by the necessary support.
Here’s what we learned, along with how Express approaches each of these important aspects.
What to Consider: 10 Crucial Questions for Bifold Door Installers
1) Who manufactures your doors?
Understanding where and how your doors are manufactured is key to ensuring the highest standards of quality. Be sure to discuss the product’s origin and the installer’s quality assurance process. At Express, most of our products, including bifold doors and sliding doors, are crafted in our advanced 200,000-square-foot facility in Leeds. With a skilled team of over 200 staff, we use the latest CNC machinery to meet high standards in British craftsmanship. By overseeing each step of the production process, we guarantee the quality of the doors delivered to your property.
2) Are your installers employees of the company?
Proper installation is just as critical as door quality, and the best results come from skilled, experienced installers. Be sure to ask whether the company relies on subcontractors, and if so, how they monitor quality. At Express, we only use our own trained installers and never outsource to haulage companies or subcontractors. This approach guarantees that our products arrive in perfect condition and are installed with the expertise needed for a top-quality finish.
3) Do you provide on-site measurement services?
Accurate measurements are essential for a seamless installation, so it’s important to confirm whether your installer provides on-site measurement or if you’ll need to manage this step yourself. At Express, we carry out a comprehensive site survey before starting any project. This allows us to meet clients on-site, discuss specific needs, and ensure every step goes smoothly. For larger commercial projects or clients who already have precise measurements, our sister company, Express Direct, offers an online service with pre-measured products, ideal for quick, high-volume orders.
4) How long has your company been installing bifold doors?
Experience is key when it comes to bifold door installation, as it demands specialised expertise. Understanding a company’s background can give you confidence in their skill and dependability. Since 2007, we have been designing and manufacturing aluminium bifold doors. With our knowledgeable, dedicated team, we support clients through each step of the process to deliver installations tailored to the unique needs of every project. Take a look at our case studies to see examples of our completed work.
5) Are your installers trained in “toe and heeling” a door?
The “toe and heel” adjustment is crucial for preventing door sagging over time. Even high-quality doors require precise installation to remain aligned, secure, and operate smoothly. Be sure to ask if the installers are skilled in this technique to guarantee lasting performance. By choosing us, you can feel confident that our experts are thoroughly trained in “toe and heeling,” ensuring optimal door performance from the moment of installation.
6) What does your standard warranty cover?
For peace of mind, it’s important to know exactly what is covered under the company’s warranty. Be sure to ask specifically which parts and labour are included, any exclusions, and whether certain conditions may apply. At Express, we provide clear and comprehensive warranties on all our products, including a 5-year warranty on integral blinds and a 10-year warranty on doors, windows, roofing systems, double-glazed units, and powder-coated aluminium. Unlike many competitors, our warranties are clear, with no hidden terms in the fine print. When we install your products, you can rely on us for full coverage, with our team ready to assist you should any issues arise.

7) Do you offer extra guarantees if you handle installation?
Opting for a company that both manufactures and installs your doors can offer valuable added protections, including certifications like those from Certass or FENSA. Working with a FENSA- or Certass-registered installer guarantees a high standard of workmanship and assures that your project complies with necessary planning permissions and building regulations. At Express, we are proudly Certass-certified, underscoring our dedication to quality and reliability. This certification means you can trust that our team will professionally manufacture and install your doors, ensuring a smooth process and long-lasting confidence in the result. For more insights, see our blog on the importance of Certass and FENSA certifications.
8) How do you achieve a low threshold?
Thresholds are key to accessibility, as they make it easier to move between indoor and outdoor spaces. While sliding doors typically allow for a low or flush threshold more easily, achieving a completely flush finish with bifold doors can be more challenging due to the need for effective drainage to prevent water from pooling at the base. Ask your installer about options for creating a low or flush threshold that provides smooth access while maintaining durability. Our bifold systems are designed with accessibility in mind, allowing us to create a seamless transition between interior and exterior floors when drainage is properly managed. For added protection against water ingress, we recommend a slight rebated upstand between the internal and external floors. Not only will this help keep the installation weather-tight, but it will also improve durability while maintaining the smooth, accessible flush threshold.
9) If the door alignment shifts, will you provide adjustments?
Over time, doors may need slight adjustments to maintain smooth operation. It’s important to confirm if your installer offers alignment adjustments, particularly within the first year, to address any shifts and prevent issues that could affect performance. At Express, we are committed to providing ongoing support after installation. If any adjustments are needed within the first year, our customer service team will be available to assist, ensuring your doors continue to function properly and meet your expectations.
10) Do you offer aftersales support for ongoing maintenance?
Long-term support is vital for keeping your doors in good condition, so it’s important to confirm whether your installer provides assistance and guidance for future maintenance or repairs. Our dedicated aftersales team, consisting of trained professionals, is always ready to address any technical issues or remedial needs promptly. Meanwhile, our Customer Service team will reach out to gather feedback and follow up on any concerns, keeping you informed throughout the lifespan of your products. Additionally, we offer an online help desk with instructional videos to help clients properly operate and care for their products. When we install your products, we fully guarantee them for years, so you can expect exceptional aftersales service.
