Repairs

UPVC Doors and UPVC Window Repairs Division.

Our PVC repairs division opened in 2010 as a separate division from our manufacturing and installing arms, as previously PVC window repairs and PVC door repairs were carried out by the installations teams, however with our ever growing repairs business taking off in its own right we now have many main insurers on board with us and many have appointed us as specialist contractors.

Specialising in double glazing and conservatory repairs, we pride ourselves in providing a high standard of service which is both cost effective and reliable.

Catering for both domestic and commercial customers, over the years we have built up a loyal customer base. These include UK main Insurers, councils, schools, housing associations, nursing homes and hospitals and over 30,000 loyal domestic customers (references available).

Any job large or small is carried out with the same care and attention. All UPVC repair parts supplied come with a full manufacturer’s warranty.


If you cannot see the service you require, please contact us and we will endeavour to help you.

Misted Double Glazing

If a double glazed sealed unit has gone misty inside the seal on the glass has failed, and moisture is getting inside and between the two panes of glass, the glass unit cannot be repaired although it can be replaced without the need to remove the whole window this type of damage normally appears in the springtime after a hard winter.

We can replace sealed units of any age and type.

As temperatures change moisture will turn into liquid, which cannot escape. When sealed units are manufactured they are not designed to be taken apart again, hence when it has failed it will need replacing.

Sealed Unit Failure 

The most common cause of sealed unit failure is due to the unit not being sealed correctly during manufacture or indeed old age and occasionally impact damage. If a unit is not fully sealed all the way round, the unit is likely to fail within a relatively short time scale, and this will be normally within a year or so.

We can replace sealed units of any age and type.

French and Patio Door Repairs

As standard the maximum width for a pair of double French doors is said to be 5ft wide. One or two manufacturers make doors up to 6ft without any problems, but most are not strong enough to go over 5ft.

French doors are heavy and should have a re stricter fitted to prevent the wind straining the hinges, plus the wider the doors are the more quickly nylon wheels will wear out unless you have stainless steel wheels and track on your patio doors.
