DIY repairs versus a professional job
If you’ve already tried a DIY fix, that is fine. We remove the old filler and start again, so it will not stop us repairing it. It does add a little time, so tell us about it when you send pictures.
The difference between a kit and a professional repair is mostly in the preparation and colour. We clean and key the area properly, mix the colour to your surface and finish it to the same sheen, and the work is guaranteed.
uPVC repair in Blaencwm, done in place
Builders and developers use us for snagging repairs too. The damage is filled and refinished so it blends into the frame, woodgrain finishes included. Our repair technicians work on conservatory frames, white uPVC and window frames & sills, and common reasons people get in touch are holes from removed fittings and alarms and damage during building work.
Big or small, you get the same one-year guarantee in Blaencwm and across Rhondda Cynon Taff. Warm soapy water and a soft cloth are all it needs. Don’t use solvents or scourers.

For landlords and businesses
Rental properties take more wear, and replacing things at every changeover adds up. Repairing between tenants keeps the property presentable for less.
For anyone letting property in or around Blaencwm, we can repair and quote for several addresses together. Send pictures for each one and we will price them together.

Repair or replace: which is better?
A new window, door or sill costs far more, and it may not match the rest after years of weathering. A repair leaves the unit in place. Repairs from £95, with every job priced individually. Rather than charging by the hour, we price the whole job up front. It depends on the damage, the material and access, and doing several items at once reduces it.

What uPVC repair costs
Repairs from £95. A fixed quote means you know the cost before you book. We look at:
- The type of damage
- The colour and finish to match
- Access to the area
- Whether we combine several jobs
No two jobs are quite the same, 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.
Getting a price from pictures
You can typically get a fixed price without us visiting. To help us price it:
- A coin beside the damage so we can judge size
- One sharp close-up of the damage
- A wider photo showing the entire window, door or sill
- Natural light rather than flash
The quickest way to a price is to send a couple of photos through our quote form or ring us. We’ll say immediately if a repair is the right fix.
