Can a cracked uPVC cill be repaired instead of replaced?
Often, yes. Where the cill is still sound and secure and the damage is localised, the section can be rebuilt and refinished in place without disturbing the window above it.
Windows, doors & trims
Damage to a uPVC frame or cill is rarely a reason to take a window or door out. Where the profile is sound and the damage is on the surface, we repair in place — so the glazing, sealant and surrounding plaster or brickwork stay exactly as they are.
We work on white, coloured and foiled woodgrain-effect uPVC across window frames, door frames, cills, trims and add-on profiles. Foils and textured finishes vary considerably, so the profile and the finish are always identified at assessment before any work is agreed.

Scope
Damage
How it works
You send clear photographs of the damage and a wider shot of the frame or cill. We identify the profile and finish and confirm whether an in-place repair is suitable before anyone travels.
Glazing, seals, sills and surrounding decoration are masked and protected, and the damaged area is cleaned back to sound, stable material.
The chip, dent or damaged section is rebuilt in layers and shaped back to the original line and profile of the frame, cill or trim.
Colour, sheen and texture — including woodgrain effect where present — are matched to the surrounding surface as closely as the materials allow.
The repair is checked with you in daylight, the area is left clean, and we explain curing time and aftercare before the window or door returns to normal use.
Where we work
Honest advice
Every surface is assessed before work is agreed. Where a repair is not the right long-term answer, we will say so.

We work with white, coloured and foiled woodgrain-effect uPVC. Because foils and textures vary, we identify the finish from your photographs and confirm suitability first.
No. Our work is surface and profile repair. Glazing, sealed units, hinges, handles and locking mechanisms are a glazier's or installer's work.
Yes — frame and cill damage found at snagging is a large part of our construction work. Send photographs of the affected plots and we will confirm what is suitable to repair.
