Learn more from our FAQ

I have condensation between the glass in my window?

Moisture has gotten inside your sealed unit and the only remedy is a replacement glass unit, which is far less expensive than replacing the complete window or door.

When I close my window there is a gap and draft

There are 2 main reasons for this. Either the locking mechanism may need adjusting/replacing or the hinges may need replacing.

My door will not lock properly?

Most commonly, just an adjustment is required. But only if the door lock works when the door is in the open position.

The handle on my window is turning, but the window does not open

This could be due to the handle is faulty, or the locking mechanism inside the window is broken, but both can be repaired, just ask us for a free quote.

Do you give free estimates and advice over the phone?

Yes, if you can tell us about your double glazing problems, we can normally diagnose and supply you with a price over the phone. Same goes for other needed repairs.

What guarantee do I receive?

10 year backed guarantee insurance.
