Frequently Asked Questions (FAQs)

Q: Do misted windows always need replaced?

No. In most cases, only the glass unit needs replaced, not the entire window frame.

Q: Why are my windows stiff or hard to open?

This is often caused by worn hinges, failed mechanisms, or dropped sashes. These issues can usually be repaired.

Q: Can draughty windows really be fixed?

Yes. Draughts are commonly caused by worn seals or poor alignment, both of which we regularly correct.

Q: How long do repairs usually take?

Many repairs are completed within a single visit, depending on the issue and parts required.

Q: Are your repairs guaranteed?

Yes. All repairs are covered by a 2-year warranty for peace of mind.

Q: Do you work on older uPVC windows?

Yes. We regularly repair older uPVC windows and doors, even those that are no longer manufactured.
