What is the cost of patio door replacement?

On average, a patio door replacement costs somewhere between £1,000 – £5,000.  The exact quote will depend on a number of factors, such as:

• Type of frame – uPVC doors are typically at the cheaper end of the spectrum at around £900, while aluminium door frames costs start at £1,800.
• Type of glass – Tempered or laminated glass solutions are recommended for privacy and security, but this material will cost a bit higher than regular glass.
• The mechanism of the door –  French doors are a popular choice for patio doors, and prices can range from £500 up to £1,500.
  A sliding door glass replacement will cost around £900 for a double-panel door and £2,700 for a three-panel door. A bi-fold four-panel door will cost upwards of £3,000. 
• Your location – Prices tend to skew higher in London and big cities compared with quotes in rural areas.

If you only require the glass of your door replaced, this will significantly lower your costs. If you have experience with replacing glass doors safely, you may be able to save on costs by conducting the labour-intensive task yourself. Just keep in mind that incorrect installation could make your property vulnerable to break-ins, not to mention an increase your heating bills.

FAQs

Can you replace the glass on a patio door?

Broken glass in a patio door is a security risk that requires urgent action. If you’re happy with the overall design, you can get a quote for the replacement of the glass alone. If you measure the size of the glass required, order and fit it yourself, this will cost around £100. However, if you don’t feel confident, a qualified tradesperson can help with installation. They will usually charge a day rate of between £150 to £200 on top of material costs.

How much does a double glazed patio door cost?

Double-glazing is essential in insulating your property for maximum energy efficiency. You can expect the costs for double-glazed patio doors to range between £150 per square metre for double-glazed glass and £175 per square metre for low emission glass.

Can patio door windows shatter on their own?

Improper installation can make patio doors vulnerable to cracking and shattering by themselves. If your glass door has broken without warning, it’s likely because the edges of the glass were chipped during fitting, causing the glass to be loose in the frame. Glass can be replaced by a professional and will only take a matter of hours to complete.

Can I replace a patio door by myself?

If you don’t have previous experience replacing patio doors, we recommend you contact a professional tradesperson for this task. Home safety is a priority for all homeowners and should not be risked by improper installation. A professional can also advise if you are modifying/creating an opening for patio doors, although this usually requires the input of a structural engineer.
