What affects the price in Caswell
Prices start from £95. We price every job individually, from your pictures. The main factors are:
- What kind of damage it is
- How much damage there is
- How hard the colour is to match
- What the surface is made of
Set against the cost of replacement, repairing generally costs far less, because nothing has to be taken out, refitted or made good. The quote lists exactly what you’re paying for.
Quotes from your pictures
Photographing the damage takes a minute, and it saves a visit. Please include:
- Daylight if possible, and no flash reflection
- A coin beside the damage so we can judge size
- Where you are, by postcode
- What it’s made of, if you know
The quickest way to a price is to send a couple of photos through our quote form or ring us. We will tell you honestly if a repair is the right fix.
Repairing versus replacing in Caswell
A new window, door or sill costs far more, and it may not match the rest after years of weathering. Repairing the damage leaves the unit in place. Our uPVC repair starts from £95. Every job is a little different, so each one is priced on its own. What’s damaged, how badly and how easy it is to reach all make a difference, and combining jobs on one visit brings the cost down.

Landlord and trade work in Caswell
We carry out planned and one-off repairs for housing associations and facilities teams in Swansea and across the UK. Repairing in place avoids the disruption of a replacement, which matters when someone is living in the home.

Common problems we fix in Caswell
uPVC is hard-wearing, but it does get damaged: ladders, tools and building work scratch and chip it, candles and cigarettes mark sills, and removed fittings leave holes.
Keep an eye out for any of the following:
- Holes from removed fittings and alarms
- Scratches from ladders and furniture
- Chips and dents
- Burns on sills
Questions to ask before you book
- When it can be used again
- How to look after the finish
- If travel is included in the price
- Whether the colour is mixed to match
Can I fix it myself?
The difference between a kit and a professional repair is mostly in the preparation and colour. We prepare the area properly, mix the colour on site and polish the finish to match, then guarantee it for a year.
You can buy a DIY kit for most repairs, and they can tidy up a tiny mark. The trouble is colour and preparation: they come in a handful of shades, and if the surface is not prepared the repair won’t last.
