uPVC sliding patio doors in Dunoon: what to know
Here is what to weigh up if you are considering uPVC sliding patio doors for a home in Dunoon:
Where a patio door in Dunoon opens onto a conservatory or narrow side return, a sliding panel avoids the clash a hinged door can have with furniture or a gate.
Replacing a tired patio door in Dunoon? A uPVC slider usually fits the existing opening, so the job is a straight swap rather than building work.
- 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.
- Steel reinforcement inside the main profiles keeps the frame rigid, holds the locking hardware firmly and stops the sliding panel flexing over the years.
Daylight in Dunoon and what it means for your glass
Daylight in Dunoon runs from about 6 h 57 min in December to 17 h 36 min in June, with the noon sun at roughly 11° and 57° respectively. Use that to choose your glass: standard low-E double glazing for north and east elevations, and consider solar-control or triple glazing for sunny south and west walls.

Timescales for uPVC sliding patio doors in Dunoon
Surveys in the PA23 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.
Do you need approval in Dunoon?
Scottish building standards still apply to a replacement door even where no warrant is needed, so the door must meet the energy and safety glazing requirements. If the opening is being formed or widened, a building warrant is required before work begins.
Options to consider for your uPVC sliding patio door
- Threshold. A standard threshold for a straight swap, or a lower threshold where the floor build-up allows.
- Foiled colours. Anthracite grey, black, cream or woodgrain foils on one or both faces, for an extra charge.
- Glass. Toughened double glazing as standard, with laminated, obscure or solar-control units available.
Questions about uPVC sliding patio doors in Dunoon
Can you match other doors and windows in my Dunoon home?
Usually, yes. Most aluminium and uPVC systems come in standard RAL colours and finishes, and we can quote dual colour where the inside and outside need to differ. Bring photos of existing frames to the survey.
What sizes do uPVC sliding doors come in?
uPVC sliding doors are made to measure, so they come in any size within the system limits rather than set sizes. Our uPVC range covers overall widths from about 1.5 m to 3.6 m at standard 2.1 m height. Two panels cover most openings up to about 3 m, and beyond that a third panel is added. For larger openings, aluminium carries bigger panels.
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.
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.
