Grey uPVC windows: sprayed from £275, or replaced for thousands
Spraying starts at £275 and is priced per property rather than per window, so a bay, a bathroom top-light and a front door do not arrive as three separate bills. Most whole-house jobs are two to three days on site, and a typical three-bedroom semi comes in around £1,100.
Every colour costs the same. Anthracite, agate, slate, graphite or a shade nobody has asked us for before — the RAL number you pick does not change the price. Choose the grey you actually want rather than the one you assume is cheapest.
Replacing the same windows in grey runs into thousands, takes weeks to order, and puts frames that are structurally fine into a skip. Spraying keeps the glass, the locks and the hinges exactly where they are.
You get a fixed written price before we start — not a range and not a day rate. It comes from your postcode and the number of windows, so for most houses there is nothing to measure up and nobody to let into the house to price it.

Anthracite grey, agate, slate, graphite — which grey?
Grey is not one colour, and the shade matters far more than people expect once it is on fourteen frames. These are the ones we spray most, each matched to a RAL reference so what you approve on paper is what turns up on the house.

Anthracite grey (RAL 7016)
The dark, near-charcoal grey used on most new-build windows, and the colour we are asked for more than any other. It reads almost black on a dull day and clearly grey in sun. It sits comfortably on red brick, render and stone alike, and it is what nearly everyone means when they say anthracite windows.
Agate grey and light grey
Agate grey (RAL 7038) is the soft, pale grey — closer to warm stone than to charcoal, and much quieter on a period property or a pale render. Light grey (RAL 7035) is paler again. Both are the usual answer when white feels stark but anthracite feels too heavy for the house.
Slate, graphite and pebble grey
Slate grey (RAL 7015) is the one people most often confuse with anthracite. It is a shade lighter and noticeably bluer; anthracite is darker and more neutral. Across a full elevation the difference is obvious. Graphite grey (RAL 7024) sits between the two and runs slightly warmer than slate. Pebble grey (RAL 7032) is the palest of the set, closer to a grey-beige.
We can spray any RAL colour, not only these — the full RAL colour chart is here — in matt, satin or gloss. Window frames, sills, doors and conservatory frames are all sprayed to the same reference in the same visit, so nothing is left mismatched.
Grey uPVC window spraying: before and after
White uPVC that has yellowed over fifteen years, and the same frames in anthracite grey. Same windows, same glass, same house, two days apart.
It is the quickest way to answer the thing everyone asks first — whether it will look sprayed. It should not. It should look like the frames came that colour.

Before you commit
Are grey windows going out of fashion?
Honestly? Possibly, one day. Grey has been the default exterior colour for over a decade, and no colour holds that position forever. Anyone who tells you it is permanent is usually selling you something with a twenty-year commitment attached to it.
Which is the whole point.
Buy new grey windows and you are betting several thousand pounds, and the next twenty years, on a colour staying in favour. Have the windows you already own sprayed grey and you are spending from £275 — and if the fashion moves, or you simply go off it, the same frames get sprayed again.
That is the difference, and it is not one a window company can offer you. They have to hope grey lasts. We do not. Anthracite is what we are asked for most today; if in fifteen years that has become sage green or off-white, it is the same job on the same frames.
So choose the shade you actually want to look at, rather than the one you think will still be correct in fifteen years’ time. Changing your mind later costs a fraction of getting it wrong the first time.
Our 10-year insurance-backed guarantee
Every window we spray carries a 10-year insurance-backed guarantee against peeling, cracking and flaking.
Insurance-backed matters more than it sounds. It means the cover is underwritten — it does not rest on us still being here in year nine. The paperwork follows by email once the job has been inspected and signed off, so it is on file rather than in a drawer.
“I was a little anxious about having a re-spray rather than replacing existing doors. However, from my initial chat with Kapre, choosing the colour, booking a date and the work completed, the whole process was faultless.”
— Debbie, Google review
Do sprayed grey uPVC windows fade?
This is the fair question, and it is really a question about who does the work.
We spray a two-pack industrial uPVC coating, applied by airless sprayer in thin, even coats. It cures hard and bonds into the frame rather than sitting on top of it. That is what separates it from a tin brushed on at the weekend — and brush-on jobs are the ones that lift at the edges after a couple of summers.
Darker colours do work harder. Grey window frames absorb more heat than white ones and take more UV with it, which is why the coating is specified for exterior use rather than picked off a shelf, and why the preparation underneath it matters as much as the paint.
Nothing outdoors is permanent. The difference is whether it is in writing: ours is guaranteed for ten years against peeling, cracking and flaking.
Grey outside, white inside — yes, we can do that
A lot of people want anthracite grey on the outside of the house and white left on the inside, so the rooms stay light. It is one of the few things spraying does more easily than replacing.
Sprayed, it is simply a question of which faces get masked. It works the other way round too, and the inside can be a different grey again if that is what suits the room. The join runs where the frame turns, so it is a clean line rather than a compromise.
Worth deciding before the quote rather than after, because it changes the masking and the time on site.
How we spray uPVC windows grey
- Free fixed quote. Your postcode and the number of windows is enough. You get a fixed written price, no visit needed for most houses, and the figure does not move once work starts.
- Preparation. Frames are cleaned, degreased and lightly abraded so the coating has something to key into. This is the part that decides how long the finish lasts, and it is the part a rushed job skips.
- Masking. Glass, handles, hinges, seals, sills and brickwork are all masked off. Nothing is removed and no scaffolding goes up on a standard house — you keep the windows, the glass and the locks you already have.
- Spraying. Two-pack uPVC coating goes on by airless sprayer in thin, even coats, in matt, satin or gloss.
- Inspection and guarantee. We walk the job with you, take the masking off, and the 10-year guarantee paperwork follows by email.
How long it takes
Two to three days on site for a typical house, start to finish. There is no manufacturing lead time, because there are no frames to order — the only wait is for a slot in the diary.
The same process, in more detail, is on our uPVC window spraying page.

Can you spray white uPVC windows grey?
Yes — it is the most common job we do. White frames, woodgrain frames and frames that have yellowed with age can all be sprayed grey where they stand, along with conservatories, front and back doors, garage doors, and sash, casement and bay windows.
The one condition is that the frames still work. If they open, close and seal properly, the colour is the only thing wrong with them and spraying is the fix. If a unit has blown or a frame is failing, that window needs replacing, and we will tell you so rather than spray over it.

Grey uPVC window spraying FAQs
Are grey uPVC windows more expensive than white?
When you buy new, grey is usually a paid-for option on top of white. Sprayed, every colour costs the same — the price comes from your property and the number of windows, from £275.
Can you spray white uPVC windows grey?
Yes, and it is the job we do most. If the frames still open, close and seal properly, white, woodgrain and yellowed uPVC can all be sprayed grey in place.
Are grey windows going out of fashion?
Grey has led for more than a decade and is still what we are asked for most. It may not lead forever — but sprayed frames can be sprayed again, so it is not a twenty-year decision.
Do grey uPVC windows fade?
Sprayed and cured properly, a two-pack industrial coating holds its colour for years. Dark greys take more heat and UV than white, which is why ours carries a written ten-year guarantee.
How much does it cost to have uPVC windows sprayed?
From £275, priced per property rather than per window. A typical three-bedroom semi is around £1,100, and any RAL colour is the same price. You get a fixed written price before anything starts.

RAL 7016. Slate grey is RAL 7015, agate grey is RAL 7038, graphite grey is RAL 7024 and pebble grey is RAL 7032.
What is the difference between slate grey and anthracite grey?
Anthracite (RAL 7016) is darker and more neutral; slate (RAL 7015) is a shade lighter and noticeably bluer. Across a full elevation anthracite reads almost black in dull weather.
How long does spray painting uPVC windows last?
Years, when the preparation is done properly — cleaning, degreasing and abrading is what the finish stands or falls on. The guarantee runs for ten years against peeling, cracking and flaking.
