What uPVC sliding patio doors offer homes in Derry/Londonderry
These are the points a surveyor will go through with you when you choose uPVC sliding patio doors for a home in Derry/Londonderry:
If the windows on your Derry/Londonderry home are white or woodgrain uPVC, uPVC sliding patio doors in a matching finish keep the rear of the house looking uniform.
The rules for a replacement door in Derry/Londonderry are checked at survey, and your written quote says which approval route applies to your home.
- Multi-chambered uPVC profiles trap still air inside the frame, so the frame itself insulates well without needing a separate thermal break.
- As the least expensive sliding door material, uPVC lets you replace a draughty older patio door with modern double glazing on a modest budget.
- Compressible gaskets and brush pile seals along the interlock reduce the draughts and rattles that an older patio door with worn seals often suffers from.

Survey, manufacture and fitting around Derry/Londonderry
Surveys in the BT47 district are booked at a time that suits you. After you approve the quote, manufacture is typically 2–4 weeks from survey sign-off; on fitting day the old door comes out, the new frame is set level and sealed, and the panels are adjusted so they glide properly. Fitting usually takes 1 day for a straight swap in an existing opening. Derry/Londonderry is in an area we cover by arrangement: the survey is still free, and survey dates, delivery and any travel cost for delivery and fitting are confirmed in your quote before you order.
Do you need approval in Derry/Londonderry?
Building control in Northern Ireland is run by district councils under the Building Regulations (Northern Ireland). We take on work in Northern Ireland by arrangement and confirm what approval your door needs before anything is ordered.
Which options matter for uPVC sliding patio doors?
- Panel layout. Choose which side slides, or a three-panel layout for openings beyond about 3 m.
- Threshold. A standard threshold for a straight swap, or a lower threshold where the floor build-up allows.
- Trims and cills. A matching uPVC cill, add-on trims and internal finishing so the new door sits neatly against existing plaster and brick.
Questions about uPVC sliding patio doors in Derry/Londonderry
How soon can you survey in Derry/Londonderry?
Survey dates in the BT47 district are arranged individually when we reply to your enquiry. After you approve the written quote, manufacture is typically 2–4 weeks from survey sign-off.
How quickly can a uPVC patio door be fitted?
A uPVC sliding patio door is typically made in 2–4 weeks after you sign off the surveyed specification, the shortest lead time of the sliding door materials. A straight swap in the same opening typically takes 1 day, including removing the old door, fitting, sealing and making good inside. Times are typical rather than promised, and foiled colours can add a little time.
Should I choose uPVC or aluminium for a sliding door?
Choose uPVC if budget and a quick, simple replacement matter most, and aluminium if you want slimmer frames, bigger panels or a powder-coated colour. uPVC insulates well and costs less, but its frames are wider and its panels smaller. Aluminium suits openings over about 3.6 m and modern extensions. Our aluminium vs uPVC guide sets out the differences.
How much do uPVC sliding patio doors cost?
uPVC sliding patio doors start from a guide price of £1,695 for a 1.5 m two-panel door, fitted, inc VAT, at standard 2.1 m height. A 2.4 m door is a guide £2,195–£2,695, and a 3.6 m three-panel door is around £2,895. Coloured foils, glass upgrades and a low threshold move the figure up, and the final price is fixed in a written quote after survey.
