Diagnose first. Repair second.
Our repair-first approach starts with the symptom but does not stop there. A handle that feels stiff can be the result of a worn mechanism, poor alignment or a sash that has dropped. Replacing only the obvious part can leave the underlying fault in place, so we inspect the opening, hardware and alignment before specifying the repair.
Survey detail that helps get the repair right.
Where identification matters, the survey records measurements, hardware markings and photographs against the exact window at the property. That gives the office and engineer a reliable record for sourcing parts and means future work can refer back to the same physical asset.
One repair or a whole property.
We work on domestic, landlord and commercial properties and can deal with a single faulty window or survey multiple units across a property. If the glass has failed as well as the hardware, we can measure the sealed unit and include that in the same repair plan.
Frequently asked questions
Can a uPVC window be repaired without replacing it?
Often, yes. Hinges, handles, locks, espags, gaskets and other serviceable components can frequently be repaired or replaced while retaining the existing frame.
Why will my uPVC window not close properly?
Common causes include worn hinges, a dropped sash, misalignment or a locking mechanism that is not engaging correctly. The right repair depends on diagnosing which component is causing the problem.
Can you repair a window that will not lock?
Yes. We can inspect the handle, espag or other locking hardware, keeps and sash alignment and specify the failed component rather than assuming the whole window needs replacement.
Do you repair draughty uPVC windows?
Yes. Draughts can be caused by worn gaskets, poor compression, hinge wear or alignment problems. We assess the cause before recommending seals or adjustment.
