What affects the cost of installing a patio door?
The cost of putting in a patio door will depend on a few key factors. Here’s what can influence the final price.
Type of patio door
The style you choose makes a big difference. Sliding doors tend to be more affordable, while French and bi-fold doors often cost more due to their design and hardware.
Size of the door
The bigger the opening, the higher the cost. Larger doors require more materials and more time to install, which pushes the price up.
Material
Patio doors come in a range of materials, including uPVC, aluminium, and timber. uPVC is the most budget-friendly, while aluminium and wood typically sit at the higher end of the price range due to their finish and durability.
Glass type
The type of glazing you choose matters. Double glazing is the most common, but if you’re after improved insulation or soundproofing, triple glazing is available. Just expect to pay more.
Single glazing is rare for external doors and often doesn’t meet building regulations.
Location
Where you live can affect labour and material costs. Homes in London and the Southeast, for example, tend to face higher rates compared to other parts of the UK, due to higher labour and material costs.
Installation complexity
Straightforward jobs will cost less. But if your opening needs structural work or your home is older and requires adjustments, you may pay more for installation. The experience and reputation of your installer can also influence the final price.
