Should you replace it?
A new window, door or sill is a much bigger job, and it may not match the rest after years of weathering. Repairing the damage leaves the unit in place. Repairs from £95, with every job priced individually. Most people are surprised how affordable a repair is, especially compared with replacing and refitting. Photos let us give you the exact figure.

What else we do in Castle
DIY kit or professional repair?
If you do try a kit, read the instructions carefully, make sure the area is clean and completely dry, and do not use it until it has fully cured. If it fails, we can still put it right.
For a hairline mark somewhere you will never see, a kit may be enough. For anything you look at every day, anything that has rusted, cracked or holed, or anything on a coloured surface, a professional repair is worth it.
Prices and what affects them
Repairs from £95. We charge the same across the UK, including Castle. What changes the price is:
- The size and number of damaged areas
- The colour and finish to match
- The material and finish
- Whether we combine several jobs
Compared with replacing, a repair is normally a fraction of the price, because there is no removal, plumbing or making good. Your fixed quote shows exactly what’s included.
Send pictures for a quote
The better the pictures, the more accurate the price. Here’s what helps:
- Your postcode, so we can check dates

- A close-up of the damage, in focus
- A coin or ruler next to the damage for scale
Most clients in Castle get their price from photos. Add a line about what happened and your postcode, and we will reply with a fixed quote and the earliest dates we have.
