Can You Paint uPVC Windows and Doors? Paint It, Have It Sprayed, or Replace

White uPVC is sold on never needing paint, so the question tends to come up for one of two reasons: the frames have yellowed or gone chalky, or the house wants a different colour and the windows are otherwise fine. Both have three answers. You can paint the frames yourself for the cost of a few tins, pay a sprayer, or replace the windows in the colour you want. This guide puts the three side by side, with what each one does and does not fix. For keeping unpainted frames clean, our double glazing aftercare guide covers the routine; this page starts where cleaning stops.

Can you paint uPVC?

Yes, according to every paint maker we checked. Rust-Oleum sells a uPVC door and window paint it describes as self-priming, with a "10 year performance" claim. Valspar sells a uPVC and composite paint with "no primer required", listed for uPVC windows, fascias and composite doors. Zinsser says its AllCoat Exterior is self-priming on plastic, and Dulux sells Weathershield Multi-Surface, which it says can go straight onto a uPVC door. Frenchic sells Al Fresco for uPVC and composites.

The people who make and fit the frames are warier. Eurocell, a profile maker, says that "as a general rule of thumb, no", painting uPVC windows is not recommended. Everest says uPVC doors can be painted "if it's done the right way", and then that you should not, because uPVC was not designed to be painted. Bear in mind who is talking: the "do not paint, replace" advice comes from companies that sell replacement windows, and the "paint it" advice from companies that sell paint. Both can be right about their own part of it.

Paint, spray or replace: the costs side by side

The three routes differ by an order of magnitude, and so does what they buy you. Painting or spraying changes the colour. Replacing changes the colour and everything else: glass, seals, hardware and frame. The figures below are dated and sourced; the replacement row is the site's own uPVC price.

Source: Checkatrade uPVC spraying (July 2026) and coloured uPVC window (July 2026) cost guides; MyJobQuote uPVC spraying guide (September 2026); DGCC 2026 price dataset for replacement. Research in lib/research/paint-upvc-windows-2026.md.

On those figures, a sprayed window at £150 is under a quarter of a typical £650 replacement, which fits Checkatrade's own estimate that spraying usually costs 20 to 25% of replacing. MyJobQuote puts the saving lower, "60% to 70% cheaper than replacement", and its own replacement figures start at £300 a window, below ours. The sources disagree on the ratio, not on the direction. For a semi-detached house, MyJobQuote's £1,000 to £1,800 to spray sits against £5,000 to £12,000 to replace in uPVC on our figures, and the uPVC window calculator prices replacement for your own house.

Two cautions on the table. The DIY paint figure is MyJobQuote's, and we could not check it against a named uPVC paint; the one maker price we saw, Dulux's Multi-Surface at £46, does not say which pack size it is for. And there is a fourth route the table leaves out, vinyl wrap applied to the existing frames. The only price we found is one wrapping firm's own, £80 to £500 a window with a finish it says lasts up to 10 years, so treat it as a single self-reported figure.

What paint and spray do not fix

MyJobQuote's spraying guide is plain about the limits: spraying will not fix damaged, cracked or warped frames, and will not improve the energy efficiency of old windows. Its signs that replacement is needed are frames that are warped or cracked, frames that are draughty and leak, and double glazing that has failed. One sprayer puts it in a line: spray good windows that look tired, replace bad windows that no longer perform. So check before you paint. A draught is usually a seal or a hinge, covered in our draughty windows guide; misting between the panes is a blown sealed unit, which a new unit fixes and paint does not. If several of those are true at once, the decision is the one in repair or replace, not a colour.

How to paint a uPVC door or window

The steps below are drawn from the makers' own instructions: Rust-Oleum, Zinsser's datasheet, Dulux and Frenchic. Where they disagree, we say so, and the answer is the same each time: do what the tin in your hand says.

1. Check the frame and the forecast

Paint only a sound frame. Foil-wrapped frames, the woodgrain or coloured laminate finish, are not a DIY paint job: Rust-Oleum says its paint is not suitable over vinyl-wrapped doors. One sprayer says stable foil may take a professional coating, but that a coating "cannot permanently secure foil that is already bubbling, shrinking or detaching". Then the weather. Rust-Oleum, Zinsser, Dulux and Frenchic all set a floor of 10°C. The upper limits differ: 25°C for Rust-Oleum, 32°C for Zinsser and Frenchic. Rust-Oleum adds no direct sunlight and no rain due; Frenchic says to check the forecast for the next 48 hours.

2. Clean and degrease

Take off what you are not painting. Dulux says to remove door furniture such as knobs, knockers and an ornate letterbox. Then wash the frame: Rust-Oleum and Frenchic both specify sugar soap and water, Frenchic says to rinse and dry with a clean cloth, and Rust-Oleum says to treat any mould or mildew with a fungicidal wash first. Zinsser wants the surface free of dust, grease, wax and mould. This is a degrease for paint, not routine cleaning; for that, and for what never to use on uPVC, see the aftercare guide.

3. Sand and prime only if the tin says so

This is where the makers split, and no single answer is right.

Source: maker product pages, guides and the Zinsser datasheet (issued June 2026), read 19 September 2026. Research in lib/research/paint-upvc-windows-2026.md.

Some guides go further than the makers. HomeBuilding says that although many paints say no primer is needed, one is "essential" for a durable finish on a uPVC door, and Screwfix says to use a primer made for plastics. That contradicts the makers of the self-priming paints; where the two disagree, the tin is the instruction written for that paint. If you do sand, HomeBuilding suggests 180 grit, lightly, just to take the sheen off, and Frenchic says to wipe the dust off with a lint-free cloth afterwards.

4. Mask everything that moves or seals

Frenchic says not to paint silicone seals or beading. One installer's masking list covers glass edges, brick and render edges, rubber seals and gaskets, and trickle vents and hardware you are not removing. Paints4Trade adds that paint must not get into hinges, locks or drainage channels. The drainage slots along the bottom of the frame matter most: they let rainwater out, and a frame whose slots are painted shut holds water where the sealed unit sits.

5. Apply two coats

Rust-Oleum and Zinsser both call for two coats, and Zinsser suggests an extra one on sills and other exposed spots. Leave the recoat time in the table between them. If you are spraying rather than brushing, Rust-Oleum says to thin its paint with 10 to 20% water, and Frenchic says a sprayed finish needs at least three coats, two hours apart. The makers put coverage at about 8 to 14 square metres a litre per coat, depending on the product.

6. Let it cure

Touch dry is not finished. Dulux says newly painted doors and windows should not be closed until the paint has fully hardened. Full cure is 7 days for Zinsser and three weeks for Frenchic, which asks for gentle treatment for the first 48 hours. Plan the job for a spell when the windows can be left alone.

One household's account is a useful check on all this. The writer at Moral Fibres painted a front door in Zinsser AllCoat, anthracite grey, and reported it still looking good after six years. The matt version developed a white bloom on a north-facing, exposed door, and Zinsser advised that the satin would have suited it better. Sheen matters as well as colour.

Dark colours on white uPVC

Anthracite grey and black are the colours people most often want, and they are the ones with a problem the tins mostly leave out. Of the paint makers' product pages we checked, only Dulux's warns about it: its Multi-Surface page recommends "light colours only, particularly on south facing elevations", to avoid solar heat damaging the uPVC. Frenchic's blog says uPVC doors can warp in hot conditions and suggests avoiding dark colours on a south-facing door. Zinsser, by contrast, sells its uPVC-capable paint ready-tinted in anthracite grey and black.

The physics is simple: dark colours absorb more sun and turn it into heat. RegaLead, which makes building-product paints, measured the heat build-up above the surrounding air on uPVC profile: 22.33°C for white, and 42.22°C with standard black paint, which it calls "more than enough to warp a frame". Its own infrared-reflective black came in at 24.91°C. It puts uPVC's expansion at about 1.2 mm per metre for every 20°C. Three caveats: RegaLead sells the reflective paint it tested; the same page gives other figures for standard black, up to 44°C; and it says steel or aluminium reinforcement in the profile improves on those numbers. Still, the direction is not in dispute. The industry fitting guide already allows coloured and foiled uPVC a bigger fitting gap than white because it expands more in sun, as our guide to fitting a double glazed window sets out.

Factory colour can avoid some of this. Foil maker RENOLIT uses infrared-reflecting pigments in its window films to cut heat build-up. We found no retail DIY uPVC paint sold as solar-reflective, and no sprayer that says it uses one. If you want a dark frame on a sunny elevation, that is an argument for replacing in a factory colour rather than painting white frames dark.

Professional spraying: what you are paying for

A sprayer is not using the tins above. Checkatrade (July 2026) says most uPVC needs "a two-pack spray coating applied with a professional spray gun", and that rattle cans rarely bond properly and tend to peel. One Birmingham sprayer lists what its quote includes: masking of brickwork and glass, degreasing and abrading the frame, a flexible adhesion primer and two coats of 2K polyurethane top coat. Another removes opening sashes where needed so the edges can be finished. The preparation is most of the value: Checkatrade warns that sprayers who skip it get paint that peels within a few years, and the Birmingham firm says cheap quotes that skip prep typically peel within 18 months.

The work is quick. Checkatrade says a standard semi, windows and front door, takes one to two days, and a single door a few hours; the masking goes on the day before or that morning, so expect limited use of the windows on the day. MyJobQuote puts a detached house at two to three days. The Birmingham sprayer says frames are touch-dry within an hour, can be opened gently the next day, and are fully cured within 7 days.

Checkatrade's table does not make clear whether VAT is included. Research in lib/research/paint-upvc-windows-2026.md.

The outlier is Plastic Surgeon, the national repair firm, at around £80 to £120 a window. It is also the only one we found offering a 12 month guarantee rather than the 5 to 10 years Checkatrade calls standard, so the two prices are not for the same thing. Get the guarantee in writing, with what it covers: MyJobQuote says some coatings carry 10 years against the paint coming away and 5 against excessive fading. Custom and RAL colours, such as anthracite grey, can add to the price, and upper floors may need scaffolding. One sprayer adds £80 to £150 for a bespoke colour match and says London and the South East run 20 to 30% higher, but those are its own figures, with no second source.

Ask a sprayer what the preparation is before you ask what the price is. Every source that explains peeling blames skipped preparation, and every cheap quote has to save the money somewhere.

Does painting uPVC void the guarantee?

It can, but nobody we checked publishes the clause that says so. We read the guarantee pages of Eurocell, Everest and Safestyle. Eurocell gives a 10-year guarantee whose full terms sit in PDFs we could not open. Everest covers parts and materials for 10 years with no mention of paint. Safestyle says "exclusions apply" and does not publish them on the page. The only direct warning is on Everest's advice page, not its guarantee: it says DIY painting "can void the warranty" and to check with the supplier first. Everest and Safestyle are the same company, and both sell replacement windows.

So do not take it as settled either way. If the frames are still inside their guarantee period, read the terms, then ask the installer or the profile maker in writing before you paint. One thing is written down: Eurocell's care guide says solvents such as white spirit damage the surface finish of its frames, which matters if you choose a solvent-based paint thinned with white spirit. Once the frame is painted, the finish rests on the paint's or the sprayer's own promise instead: Dulux guarantees 6 years of weather protection, Rust-Oleum and Valspar claim 10, and Zinsser says up to 15.

Planning permission, conservation areas and listed buildings

In England, painting the outside of a building is permitted development. Class C of Part 2 of the General Permitted Development Order 2015 covers "the painting of the exterior of any building or work", and defines painting to include "any application of colour"; the only exclusion is painting for advertisement, announcement or direction. The Planning Portal lists "repainting window and door frames" among work that does not usually need permission.

The exceptions:

• Article 4 directions.A council can remove the right with an Article 4 direction, and the Planning Portal says so. Brighton & Hove's direction for the Queen's Park conservation area, in force since June 2022, needs permission to paint street-facing elevations that have not been painted before or in a significant change of colour, and says window frames "must be painted white". Class C itself has no conservation-area exception, so it is the Article 4 direction that bites; your council will tell you if one covers your street. If you are weighing new windows instead, our guide to replacing windows in a conservation area covers those rules.
• Listed buildings. The Planning Portal says listed building consent is needed for any significant works, inside or out, and councils read colour differently. Mid Suffolk says you do not need consent to change the external colour of a listed building or its windows and doors, unless you are painting a surface that has not been painted before or the colour would affect its special interest. Bare uPVC has not been painted before. MyJobQuote simply says you will need consent. Ask your council first.
• Flats and leaseholds.The Planning Portal says a leaseholder may need the landlord's or management company's permission first.

The Planning Portal notes that Wales may differ; these are the rules for England.

The 12-month rule you will read about

Some guides say never to paint uPVC less than a year old, because it goes on "secreting" manufacturing resins that stop paint bonding. Everest and Homebase both say so, in almost the same words, and neither cites anything. None of the paint makers' pages or datasheets we read mentions a waiting period. The nearest is Zinsser's instruction that new or unweathered plastisols must be degreased and carefully sanded. Treat the 12 months as unproven, and new frames as a case for following the preparation on the tin to the letter.

Once painted, always painted

The case for uPVC in the first place is that it needs no paint, and our uPVC windows guide still holds for unpainted frames. Painting ends that. Everest and one Essex installer both warn that painted uPVC brings repainting with it, and they sell replacements, but the paint makers' own figures say the same: a finish rated for 6 to 15 years is a finish you will redo. A replacement uPVC window, by contrast, lasts 20 to 25 years with nothing but cleaning. Painting is the right answer for sound frames in the wrong colour. It is the wrong answer for frames that are near the end of their life, which our window lifespan guide helps you judge.

If the frames are past painting

Paint and spray change the colour and nothing else. If the frames are warped, the units are misting or the windows are near the end of their life, the money is better spent on replacement, and coloured frames cost 10 to 20% more than white from the factory. The door cost calculator prices a new door, and uPVC vs composite doors sets the two materials side by side.
