Double glazed windows provide fantastic insulation against the cold and noise from the outside, and they are major contributors to lower heating bills. On the whole, windows only require minimal regular cleaning and maintenance but with natural wear and tear and use over time, some repairs will probably be required.

The repairs we are most often required to carry out to double glazed windows involve the areas where there are moving parts, that frequently come into contact with other parts of the window or the parts that perform a function like the window handles and window locks or window hinges, friction stays and restrictor hinges.

Double Glazed Window Repairs

We provide window repairs for all types of windows including uPVC, aluminium, timber and also secondary double glazing.

Misted And Foggy Windows

Window Repairs

If you have a misted and/or foggy double glazed window, this means that your sealed glass unit has broken down and condensation has built up inside between the two glass panes so frustratingly, you won’t be able to clean it. We can help you by replacing the misted glass unit as this is often a more cost-effective solution than replacing the entire window providing the frame is in good condition.

We can repair and replace a wide variety of window handles including cockspur handles, espagnolette/espag handles (left or

right hand cranked, in line or other handles used on espag locking systems), tilt and turn window handles, uPVC window handles of all kinds, and timber casement fasteners.

We can repair and replace window locks on uPVC, aluminium and timber windows including espagnolette window locks, deadbolts (Mila, Maco, Roto, WMS, Saracen Shootbolt), window latches, timber sash window locks and more.
