Frequently Asked Questions

Getting a quote is quick and easy. Simply call us, complete our online quote form or send us a few clear photos or a short video of the problem via WhatsApp.

To help us provide the most accurate quote, include:

  • A photo of the entire window
  • Close-up images of the faulty area
  • Your postcode
  • A brief description of the problem

In many cases, we can provide an initial assessment and fixed-price quote without the need for a site visit.

Yes, many older uPVC windows can still be repaired if the main frame remains structurally sound. Handles, hinges, locks, mechanisms, seals and double-glazed units are separate components and can often be replaced individually.

Repair is usually the practical option when the frame is in good condition and the fault is limited to a handle, hinge, locking mechanism, alignment problem, seal or glass unit.

Replacement may be more appropriate if the frame is severely warped, extensively damaged or no longer structurally sound.

There are several possible causes. Your window may have dropped over time, the hinges could be worn, the locking mechanism may be faulty, or the sash could be out of alignment.

Avoid forcing the handle, as this can cause additional damage. We recommend sending us a photo or short video so we can help identify the problem before arranging a repair.

This usually indicates a fault with the internal locking mechanism rather than the handle itself. Common causes include a failed gearbox, broken spindle or damaged locking strip.

Our engineers can diagnose the exact cause and replace the faulty component where possible without replacing the whole window.

No. We do not charge a call-out fee to inspect your window. Once we have diagnosed the fault, we’ll explain the repair options and provide a clear fixed-price quote before any work begins.

Yes. All repairs are backed by our 1 Year workmanship guarantee, and replacement parts are covered by the applicable 1 Year  manufacturer’s warranty. New sealed double glazed units include a 10-year guarantee against internal condensation.

Yes. A draught doesn’t always mean the rubber seal needs replacing. Worn hinges, poor alignment, damaged gaskets or faulty locking points can all allow cold air to enter around the window.

We inspect the entire window to identify the real cause before recommending a repair.

Yes. All double glazed glass replacements are covered by our 10 -year anti fog guarantee. Every hardware repair is covered by a 1-year guarantee on parts and workmanship.

Yes, in many cases. Windows can become stuck due to failed locking mechanisms, broken handles, worn gearboxes or dropped sashes.

Our engineers use specialist techniques to safely open the window, identify the fault and carry out the necessary repair.

If condensation has formed between the panes, the sealed unit has usually failed. The glass itself cannot normally be repaired, but the double glazed unit can be replaced while keeping the existing uPVC frame.

This is usually much more affordable than replacing the entire window.

Most common repairs, such as replacing handles, hinges, locks or realigning a dropped window, can often be completed within a single visit.

Repairs involving made-to-measure double glazed units normally require an initial survey followed by a second appointment once the new glass has been manufactured.

Yes. We repair most styles of uPVC windows, including casement windows, tilt and turn windows, top-hung windows and side-hung windows. We also repair many aluminium window systems used in residential and commercial properties.

Usually not. Most window faults are caused by individual components such as hinges, locks, handles or sealed glass units. Replacing only the faulty part is often much quicker and significantly more cost-effective than installing a completely new window.
