Bifold doors have become one of the most popular home improvements in St Albans, particularly for homeowners extending kitchens, opening up dining spaces, or improving access to their gardens.
One thing we have learned is that a successful bifold door installation is about much more than simply choosing a style you like. Structural considerations, product quality, installation standards and compliance all play a major role in how your doors perform for years to come.
If you are considering bifold doors for your home, here are seven important things worth knowing before you start requesting quotations.
1. Not Every Opening Is Ready for Bifold Doors
Many homeowners assume existing French doors or patio doors can simply be removed and replaced with bifold doors.
In reality, this is not always the case.
One of the most common situations we encounter in St Albans is homeowners wanting a much wider opening than their current doors provide. Creating a larger opening often requires structural alterations, including the installation of a steel beam to support the load above.
A professional survey should assess:
- The condition of the existing opening
- Whether additional structural support is required
- Wall stability and brickwork condition
- Floor levels and threshold requirements
- Access for delivery and installation
Identifying these requirements early helps avoid unexpected costs and delays later in the project.
2. Aluminium Bifold Doors Are Usually the Preferred Option
While bifold doors are available in uPVC, timber and aluminium, most homeowners in St Albans choose aluminium systems.
The main reasons include:
- Slimmer sightlines and larger glass areas
- Greater structural strength
- Better suitability for wide openings
- Low maintenance requirements
- Modern appearance that complements extensions and renovations
For homeowners investing in kitchen extensions or garden room projects, aluminium often delivers the best balance of performance, appearance and longevity.
Anthracite Grey remains one of the most popular colour choices, although black, white and dual colour options are increasingly requested.
3. Older St Albans Properties Often Present Unique Challenges
St Albans contains a wide range of property styles, many of which present installation challenges that are not immediately obvious.
Older homes frequently have:
- Uneven brickwork
- Non standard openings
- Settlement movement
- Out of square walls
- Inconsistent floor levels
These issues are particularly common in Victorian and Edwardian properties.
An experienced installer will identify these challenges during the survey stage and account for them during installation. Precision is essential because even small inaccuracies can affect how smoothly bifold doors operate over time.
4. Planning and Building Regulations May Apply
Many homeowners are surprised to learn that bifold door projects can sometimes involve additional approvals.
In most cases, replacing existing doors does not require planning permission.
However, approval may be necessary if:
- Structural alterations are being made
- The property is listed
- The property is located within a conservation area
- Significant changes are being made to the external appearance
Building Regulations compliance is equally important.
Any new bifold door installation must meet current requirements relating to:
- Structural safety
- Thermal efficiency
- Safety glazing
- Ventilation where applicable
Choosing a FENSA registered installer helps ensure compliance and provides the certification required when selling your property in the future.
5. The Cheapest Quote Is Not Always the Best Value
When comparing quotations, it can be tempting to focus purely on price.
However, bifold doors are precision engineered systems that rely heavily on installation quality.
We have visited properties where homeowners experienced issues shortly after installation due to poor workmanship, including:
- Doors that no longer align correctly
- Difficult operation
- Water ingress around thresholds
- Draughts around the frame
- Premature hardware wear
Correcting these issues often costs significantly more than investing in an experienced installer from the beginning.
When comparing quotations, ask:
- What bifold door system is being supplied?
- Is installation included?
- Are structural works included?
- Is certification provided?
- What guarantee is offered?
6. What Do Bifold Doors Cost in St Albans?
The cost of bifold doors varies considerably depending on size, specification and installation requirements.
As a general guide:
uPVC Bifold Doors
£2,500 to £4,500
Aluminium Bifold Doors
£4,000 to £8,000+
Structural Alterations
£1,000 to £3,000+
Installation
£800 to £2,000
Factors affecting price include:
- Number of panels
- Door width and height
- Glazing specification
- Colour options
- Integral blinds
- Structural work requirements
- Site accessibility
The most accurate way to understand costs is through a professional site survey and detailed quotation.
7. Professional Installation Makes All the Difference
Bifold doors operate differently from standard doors.
Large glazed panels must move smoothly, align perfectly and remain weather resistant throughout the year.
To achieve this, installers must carefully manage:
- Frame alignment
- Track positioning
- Expansion allowances
- Drainage management
- Weather sealing
- Load distribution
Even a few millimetres of error during installation can affect long term performance.
This is why experience matters.
A properly installed bifold door system should operate smoothly, remain energy efficient and provide reliable performance for many years.
Questions We Recommend Asking Before Choosing an Installer
Before making your decision, ask any installer the following questions:
- Are you FENSA registered?
- How long have you been installing bifold doors?
- Can you show examples of local installations?
- What guarantees are included?
- Who manufactures the doors?
- Will structural work require Building Control approval?
- Is certification included after installation?
A reputable company should be able to answer these questions clearly and confidently.
