Window Frame Reconstruction

Fast Response

A badly damaged window frame doesn’t always mean the complete window needs replacing. Depending on the location and extent of the damage, suitable sections of an existing frame may be repaired or reconstructed while retaining as much of the original installation as practical.
Window Doctor provides professional window frame reconstruction and repair through our nationwide network of local branches, covering suitable uPVC, aluminium and timber windows in homes and commercial properties.
Our experienced engineers can assess damage caused by attempted break-ins, accidental impacts, vandalism, poor installation, deterioration and other problems. Where reconstruction is suitable, the aim is to restore the damaged section and return the window to safe, secure and reliable operation without unnecessarily replacing the complete installation.

Common Reasons For Window Frame Reconstruction or Repair:
Window frames can become damaged for many different reasons. Some faults remain largely cosmetic, while others can affect the security, weather resistance or operation of the window.
Common reasons for window frame reconstruction or repair include:
- Burglary damage – forced entry can crack, split, distort or otherwise damage sections of the window frame.
- Attempted break-ins – screwdrivers, crowbars and other tools can cause significant damage around opening sections and locking points.
- Jemmy and crowbar damage – deeper gouges or distortion may require more substantial repair than a cosmetic surface restoration.
- Vandalism – deliberate impact or physical damage can affect individual sections of the frame.
- Accidental impact damage – knocks, tools, ladders and other impacts can crack, dent or distort window frames.
- Poor installation – incorrectly fitted frames or fixings can contribute to movement, distortion and operational problems.
- Damaged window fixings – failed or unsuitable fixings can affect the stability and positioning of the frame.
- Frame distortion – movement or physical damage can prevent the window from sitting correctly within its opening.
- Cracked or split frames – localised cracking or splitting may require reconstruction or replacement of the affected section.
- Damaged locking areas – forced entry or repeated mechanical problems can damage the frame around keeps and locking points.
- Weather-related damage – severe weather and prolonged exposure can contribute to deterioration or movement in suitable window materials.
- Temperature-related movement – expansion and contraction can contribute to alignment or joint problems in some installations.
- Timber deterioration – localised deterioration in wooden frames may require repair or reconstruction where the remaining material is suitable.
- Previous poor-quality repairs – unsuitable fillers, fixings or alterations can sometimes require corrective work.
- General deterioration – ageing or damaged sections may eventually require more substantial repair than routine adjustment or maintenance.
The appropriate repair depends on the extent and location of the damage. A small surface defect may only require a cosmetic repair, whereas damage affecting the structure, fixings or security of the frame can require reconstruction.

Frequently Asked Questions - FAQs
Can a damaged window frame be repaired without replacing the whole window?
Yes, in many cases. Localised cracks, forced-entry damage, damaged fixing areas and other faults may be suitable for repair or reconstruction while retaining the rest of the window. The extent and location of the damage need to be assessed first.
Can you repair a window frame damaged during a burglary?
Yes. Window Doctor can repair suitable window frame damage caused by burglaries and attempted forced entry, including damage around locking areas. We can also assess associated damage to the glass, locks and other window components.
Do you repair uPVC, aluminium and wooden window frames?
Yes. Window Doctor repairs and reconstructs suitable uPVC, aluminium and timber window frames. The repair technique will depend on the frame material, construction and extent of the damage.
What's the difference between window frame reconstruction and cosmetic damage repair?
Cosmetic repair is generally appropriate for surface damage such as scratches, small holes, chips and minor dents. Reconstruction is intended for more substantial localised damage such as cracks, splits, distortion or damage around important fixing and locking areas.
When does a damaged window frame need replacing?
Complete replacement may be appropriate where damage is too extensive for a reliable reconstruction, the frame has significantly deteriorated or the wider installation is no longer suitable for continued use. Where the damage is localised and the remainder of the window is serviceable, repair or reconstruction may be possible instead.
