UPVC Window Spraying vs Replacement: The Surrey Homeowner’s Guide
If you’re weighing up UPVC window spraying vs replacement in Surrey, you’re probably looking at faded, discoloured frames and wondering what the sensible move is. I’ve been asked this question hundreds of times since we started in 2004. My honest answer: for most Surrey homeowners, spraying wins — not because it’s cheaper, but because when it’s done properly, the result is better than most people expect and the disruption is a fraction of what replacement involves. This guide will walk you through both options clearly, so you can make the right call for your home.
Why UPVC Fades in the First Place
UPVC doesn’t last forever in its original colour. UV exposure breaks down the surface pigment over time, especially on south-facing elevations. White frames turn grey or yellow. Coloured frames lose their vibrancy. The UPVC itself is structurally fine — the frames, seals, and hardware are doing their job. It’s purely a surface issue. That’s exactly what spray painting is designed to fix.
Understanding this is important. If the structure is sound, there’s no logical reason to rip out and replace. You’re solving an aesthetic problem. Spray painting is an aesthetic solution.
What UPVC Window Spraying Actually Involves
This isn’t a coat of paint and hope for the best. Professional UPVC spray painting is a multi-stage process. Here’s how we do it at Ultimate Décor.
Preparation
Preparation is where quality is won or lost. We degrease the frames thoroughly to remove years of grime, polish residue, and contamination. Any chalking or degraded surface material is addressed. We sand where necessary to give the coating a mechanical key. Surrounding glass, brickwork, and sills are masked carefully — this takes time and it’s worth it.
The Coating
We use Kolorbond and Tikkurila coatings — specialist formulations designed for UPVC. These aren’t general trade paints repurposed for the job. They bond directly to the UPVC surface, flex with the material as temperatures change, and resist UV degradation. You can learn more about the science behind these coatings at kolorbond.co.uk. We apply by spray — not brush, not roller — which means no lap marks, no texture, no brush strokes. The finish is even, consistent, and factory-smooth.
Colour Options
We can match virtually any colour, including Farrow & Ball shades. Anthracite grey frames are the most popular request right now, but we do everything from heritage cream to contemporary black. If you’re updating the exterior of your home, we can spray UPVC windows, doors, fascias, and soffits in one visit to give a completely cohesive result.
What Window Replacement Actually Involves
Full replacement means removing the existing frames from the brickwork, making good any damage to the surrounding structure, installing new frames, and resealing. It’s a significant building job. For a typical Surrey semi, you’re looking at days of work, tradespeople in and out, dust, debris, and the associated disruption. There’s also the environmental cost — UPVC is not straightforward to recycle, and manufacturing new windows carries a significant carbon footprint.
There are circumstances where replacement is the right answer. If frames are warped, if seals have failed consistently, if the glazing itself is beyond repair — then replacement makes sense. But if your frames are structurally sound and the problem is colour, you’re looking at a more expensive, more disruptive solution to a problem spraying can fix.
Comparing the Two: What Surrey Homeowners Actually Care About
Disruption
UPVC spraying is low-disruption. We work on the exterior in most cases. You don’t need to be home for much of it, your home is secure throughout, and we’re typically finished in a day or two depending on the property size. Window replacement is a building job with all the disruption that implies.
Quality of Finish
Done properly, spray painting produces a factory-quality finish. New replacement windows also look good — but the critical word is “properly.” A poor spray job will peel and fade quickly. That’s why the preparation stage and the coating specification matter so much. We back our work with a 10-year guarantee. That reflects our confidence in the process, not just the product.
Environmental Impact
We use water-based, low-VOC coatings wherever possible. Extending the life of existing UPVC frames is meaningfully better for the environment than disposing of them and manufacturing replacements. If sustainability matters to your decision, spraying is the more responsible choice.
Planning Considerations
In conservation areas — and Surrey has many — window replacement can require planning consent, particularly for changes to frame colour or profile. Spraying existing frames rarely triggers the same restrictions. If you’re in an area with conservation or Article 4 restrictions, it’s worth checking with your local authority before going down the replacement route. Which? has useful guidance on planning considerations for windows if you want to understand the rules.
When to Choose Replacement Over Spraying
I said I’d be honest, so here it is. Spraying isn’t always the answer.
- If your frames are structurally compromised — warped, cracked, or water-damaged — replace them.
- If your glazing is single-glazed and you want to upgrade to double or triple, that’s a replacement job.
- If seals are failing repeatedly and causing condensation between panes, replacement is worth considering.
- If handles, hinges, and hardware are beyond repair, factor that cost in before deciding.
But if your frames pass the structural test and the issue is cosmetic, spraying is the right tool for the job.

FAQ
Q: How long does UPVC window spraying last compared to new replacement windows in Surrey?
A professionally sprayed UPVC window, using a specialist coating like Kolorbond or Tikkurila applied over a properly prepared surface, should hold its colour and finish for 10 years or more. We guarantee our work for 10 years. New replacement windows will also last many years, but the finish of replacement windows is also subject to UV degradation over time. The longevity of a spray job comes down to the preparation quality and coating specification — which is why we don’t cut corners on either.
