The process
We work cleanly and quietly, so you can carry on at home. Protection goes down first, then the work takes a morning or an afternoon. At the end we talk you through the curing time and the aftercare.
- First the frame or panel is cleaned.
- We fill scratches, chips and holes.
- We smooth the repair.
- We match the colour, including woodgrain finishes.
- The repair is blended into the surface around it.
Preparing for the visit
- Let us know about parking or access
- Keep pets and children out of the room while we work
- Avoid using the area for a few hours before we arrive

How do I book?

DIY repairs versus a professional job
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.
DIY kits are sold for most surfaces, and they can make a small mark look better. The trouble is colour and preparation: kits come in a few standard shades, and without proper cleaning and keying the filler often lifts.
What a repair can’t fix
Not everything can be repaired, and we’ll tell you before we start. We can’t fix:
- Failed or misted double glazing units
- Broken locks, hinges or mechanisms
- Frames that are warped or out of square
Send us pictures and we’ll tell you honestly before you book.
Materials we repair
- Conservatory frames
- White uPVC
- Coloured and woodgrain uPVC
