Why Are Bifold Door Quotes So Different? A Homeowner’s Guide to Comparing Like-for-Like
If you’ve recently requested quotations for aluminium bifold doors, you’ve probably discovered something surprising – prices can vary by thousands of pounds for what appears to be the same product.
So why does one company quote £5,000 while another comes back at £8,000?
The truth is that not every quotation includes the same products, services or level of workmanship. Understanding what you’re actually paying for can help you make an informed decision and avoid expensive surprises later.
Don’t Compare Price Alone
If you want to compare different bifold door quotes, it’s natural to look at the bottom line first, but the cheapest quotation isn’t always the best value.
When comparing bifold door quotations, ask yourself:
- Are the doors from the same manufacturer?
- Are the frame depths and specifications identical?
- Is the glass specification the same?
- Does the quote include installation?
- Is VAT included?
- Are trims, cills and making good included?
- Is waste removal included?
- Is there a guarantee on both the product and the installation?
A lower price may simply mean that important elements have been left out.
The Door System Makes a Difference
Not all aluminium bifold doors are manufactured to the same standard.
Premium systems often offer:
- Slimmer sightlines
- Better thermal performance
- Smoother operation
- Stronger security
- Higher-quality hardware
- Longer warranties
While they may cost more initially, they often provide better performance and durability over the life of the product.
Check the Glass Specification
Glass accounts for a significant proportion of every bifold door.
Two quotations may look similar, but one may include:
- Higher-performance double glazing
- Solar control glass
- Acoustic glass
- Toughened or laminated safety glass
- Warm-edge spacer bars
These upgrades improve comfort, energy efficiency and security, so it’s worth checking exactly what’s included.
Installation Is Just as Important as the Product
Even the best bifold doors won’t perform properly if they’re poorly installed.
Professional installation includes far more than simply fitting the frame into an opening.
A quality installer should:
- Carry out a detailed site survey.
- Check structural openings before manufacture.
- Install the doors level and square.
- Use appropriate fixings and packers.
- Seal correctly against the weather.
- Adjust and test every panel before handover.
Choosing an experienced installer can make the difference between doors that operate effortlessly for years and doors that become difficult to open after only a short time.
Ask About What’s Included
Before accepting a quotation, ask whether it covers:
- Removal of existing doors or windows
- Disposal of waste materials
- Internal trims
- External finishing
- Making good around the opening
- Scaffolding, if required
- Building regulation compliance
- Final adjustments after installation
These items are sometimes charged separately, making an initially low quote much more expensive.
Lead Time Matters Too
It’s easy to focus on price, but delivery and communication are equally important.
Ask:
- How long will manufacture take?
- When can installation begin?
- Who will keep me updated?
- What happens if there are delays?
A company that communicates well throughout the process often delivers a smoother experience from start to finish.
The Cheapest Quote Can Cost More
We’ve all heard stories of homeowners choosing the lowest quote, only to face additional costs later.
Common problems include:
- Inferior hardware
- Poor installation
- Water leaks
- Difficult operation
- Missing finishing work
- Unexpected extras added during the project
A well-prepared quotation should be clear, detailed and transparent, giving you confidence that everything needed has been included from the outset.
