- Weatherproofing checks
- Perimeter fault assessment
- Combined hardware and seal repairs
Diagnose first. Repair second.
Replacing gasket without checking the opening can hide the real issue. If the sash has moved away from the frame because the hinges are worn, or a door is no longer pulling evenly into its keeps, a new seal alone may not restore proper compression.
Survey detail that helps get the repair right.
We inspect the condition of the existing gasket, the gap and the way the opening closes. Where a replacement seal is appropriate, the existing profile needs to be matched rather than choosing by colour or appearance alone.
One repair or a whole property.
Draught and weatherproofing work can be combined with lock, hinge, glass or handle repairs during the same survey, giving a single scope for the affected unit.
Frequently asked questions
Why is my uPVC window draughty even though the seal looks fine?
The sash may not be compressing evenly against the frame because of hinge wear, alignment or locking adjustment, so the gasket can look intact while still allowing air through.
Can all uPVC window seals be replaced?
Many can, but gasket profiles vary and the correct replacement needs to suit the frame. We inspect the existing seal and the underlying closing condition first.
Will adjustment stop a draught?
Sometimes. If the cause is poor alignment or compression rather than degraded gasket, adjustment may be part of the correct repair.
Can you check several draughty windows at once?
Yes. A survey can record each affected room and unit so repairs and parts can be quoted together.
