    UPVC Window & Door Spraying in London

    Transform tired, faded UPVC windows and doors with a professional spray finish. Any colour, weather-resistant, and backed by a 10-year coating warranty.

    Why Spray Your UPVC Windows & Doors?

    Over time, UPVC windows and doors can become faded, yellowed, or simply outdated. Replacing them is expensive and disruptive — but professional UPVC spraying delivers a brand-new look at a fraction of the cost.

    Using specialist UPVC coatings designed to flex with the material, our spray finish is incredibly durable, weather-resistant, and available in any colour you choose — from classic anthracite grey to bold heritage colours. The coatings we use are UV-stable and won't peel, crack, or fade.

    UPVC window spraying is one of the most cost-effective exterior upgrades you can make. It's ideal for homeowners who want to modernise their property's kerb appeal without the cost and disruption of full window replacement. Most projects are completed in 1–2 days.

    Why UPVC Fades and What Spraying Fixes

    White UPVC does not stay white. Years of UV exposure break down the surface of the plastic, and the result is the familiar yellowed, chalky, blotchy look that makes an otherwise sound window frame drag down the appearance of the whole property. The frames themselves are usually still perfectly functional — the seals hold, the units are intact, the mechanisms work — and only the surface has aged.

    Replacing windows purely because the frames look tired means throwing away serviceable double glazing at a cost that easily runs into five figures for a whole house, plus scaffolding, disruption and making good internally. Spraying addresses exactly the problem you actually have, at a fraction of the cost and in a fraction of the time.

    It also unlocks colour options that were never available when the windows were installed. Anthracite grey, black, cream and heritage shades transform the character of a façade, and are frequently what buyers and neighbours read as 'new windows' even though the frames are the original ones.

    The Coatings and Why They Last

    UPVC is a difficult substrate. It is smooth, non-porous and it expands and contracts noticeably with temperature, which is why ordinary masonry or gloss paint cracks and peels off it within a season or two. The coatings we use are formulated specifically for plastics: they bond chemically to the surface via a dedicated adhesion promoter and they remain flexible enough to move with the frame through the seasons.

    The topcoats are UV-stable, so they hold their colour rather than chalking and fading the way the original UPVC did. They are also weather-resistant and self-cleaning to a degree, shedding dirt with rainfall and wiping clean easily.

    The finish is sprayed, not brushed, so there are no brush marks along the frames and no build-up in the corners. Applied correctly it looks factory-coated, which is the standard the work has to meet given how closely windows are examined from both inside and out.

    Our Process and Timescales

    We start by washing the frames thoroughly to remove years of atmospheric grime, then degrease to strip out any silicone or polish residue. The surface is abraded to key it, and any minor damage is made good. Glass, brickwork, sills, ironmongery, seals and surrounding surfaces are all masked precisely — the crispness of the line where the coating meets the glass is the detail that gives away a poor job.

    An adhesion promoter is applied first, followed by multiple thin topcoats in your chosen colour. Thin coats sprayed in sequence cure harder and more evenly than a single heavy application, and they avoid the runs that would be immediately visible on a vertical frame.

    Most projects are completed in one to two days. Because the work is external and the coatings dry quickly, disruption inside the house is minimal — no rooms are out of action, there is no dust internally, and nothing needs to be removed or made good afterwards. Work is weather-dependent, so we schedule around forecast rain.

    What We Can Spray and What It Costs

    Alongside windows and doors we spray conservatory frames, fascias, soffits, bargeboards, guttering, garage doors and cladding. Doing the whole exterior at once is what produces the biggest visual change, since mismatched white guttering above newly greyed windows undermines the effect.

    Any RAL colour is available. Anthracite grey (RAL 7016) remains by far the most requested in London, followed by black, cream and dark green for period properties. We can also spray only the exterior faces or both sides depending on whether the internal white finish is still acceptable to you.

    Costs depend on the number of frames, their accessibility and the extent of the work. A typical whole-house window colour change costs a fraction of replacement. Every estimate is free and fixed in writing, and the coating carries a ten-year warranty.

    Frequently Asked Questions

    How long does sprayed UPVC last?

    The coatings are UV-stable and formulated to flex with the frame, and the work carries a ten-year coating warranty. They will not peel, crack or fade the way ordinary paint on UPVC does.

    What colours can I have?

    Any RAL colour. Anthracite grey (RAL 7016) is the most popular in London, followed by black, cream and heritage dark green for period properties.

    How long does UPVC spraying take?

    Most projects are completed in one to two days. The work is external, so there is no internal dust or disruption. Scheduling is weather-dependent.

    Can you spray fascias, soffits and guttering too?

    Yes. We spray conservatory frames, fascias, soffits, bargeboards, guttering, garage doors and cladding. Doing the whole exterior together gives the most coherent result.

    Is spraying cheaper than replacing my windows?

    Considerably. A whole-house colour change costs a fraction of replacement, and you keep your existing double glazing units and mechanisms, which are usually still perfectly serviceable.

    Can you spray the inside of the frames as well?

    Yes, we can spray exterior faces only or both sides, depending on whether you want to keep the internal white finish.
