uPVC window spraying recolours your existing window frames with a specialist coating instead of replacing them. The frames are deep-cleaned, keyed, masked and primed, then sprayed with a UV-stable polyurethane finish that bonds to the plastic. A typical house takes one to two days and the finish is guaranteed for ten years.
If your uPVC windows are structurally sound but look tired, yellowed or simply the wrong colour, spraying gives you a factory-grade recolour without the cost and upheaval of replacement. It is the single most requested service we provide, and this guide explains exactly what happens on the day, why preparation matters more than the paint itself, and what results you should expect.
Why spray instead of replace?
Most uPVC frames fail cosmetically long before they fail mechanically. The plastic discolours in sunlight, the surface chalks, and white frames date a property — but the hinges, seals and glazing are usually fine. Replacing windows that still work means paying for manufacture, removal, disposal and installation of an entire new set. Spraying reuses everything you already own and changes only the thing you dislike: the colour and finish.
Professionally sprayed uPVC typically costs 60–75% less than replacement, takes days rather than weeks, and creates almost no waste.
The process, step by step
Survey & colour choice
We inspect every frame, agree the RAL colour and sheen, and check for any repairs needed before coating.
Deep clean & degrease
Frames are washed with specialist cleaners to strip dirt, grease, silicone and oxidised residue that would stop the coating bonding.
Key the surface
Each frame is lightly abraded to give the primer a mechanical grip on the smooth plastic.
Precision masking
Glass, rubber seals, brickwork, sills and surrounding surfaces are fully masked for crisp, clean lines.
Adhesion primer
A PVC-specific primer chemically bonds to the frame — the foundation of a finish that will not peel.
Spray the topcoats
Multiple thin coats of UV-stable polyurethane are sprayed for an even, factory-grade colour and sheen.
De-mask & inspect
Masking comes off, every edge is checked, and we walk the job with you before we leave.
What makes the finish last
Longevity comes from chemistry and preparation. The coatings we use are engineered specifically for rigid PVC: they remain slightly flexible so they move with the frame through hot and cold weather rather than cracking, and they contain UV absorbers so the colour does not fade or chalk. But no coating survives poor preparation — if grease, silicone or oxidised surface is left behind, adhesion fails. That is why cleaning, degreasing and keying take up more of our day than spraying does.
Applied correctly, the finish will not peel, flake or fade in normal service, which is why we back every window respray with a manufacturer’s guarantee.
Popular colours
Anthracite grey (RAL 7016) is by far the most popular choice — it modernises almost any property instantly. Black, cream, Chartwell green and agate grey follow behind. Because the colour is sprayed, you can choose any RAL shade in matt, satin or gloss, and match doors, garage doors, fascias and gutters to complete the look. See our guide to choosing the right RAL colour.
Frequently asked questions
Can all uPVC windows be sprayed?+
Almost all. Frames need to be structurally sound and free of major damage. Heavily degraded or brittle frames are the rare exception — we assess every job honestly and will tell you if spraying isn't suitable.
Do you remove the windows to spray them?+
No. Everything is sprayed in place. Glass, brickwork, sills and seals are precision-masked, so overspray never touches the rest of your home.
How long before I can open my windows?+
The coatings we use are touch-dry in under an hour and windows can normally be used the same day. Full cure takes a few days, during which the finish keeps hardening.
Will sprayed windows look painted?+
Not when done professionally. Spray application lays down a thin, even, factory-style coat with no brush marks. Most visitors assume the windows are new.
