Double Glazed Sealed Units

Double Glazed Sealed Units can breakdown and mist up. There are many causes of condensation build up inside a sealed unit such as poor manufacture, incorrect installation procedure, cheap components in the unit, age of the unit and lastly block drain holes in the UPVC Window. Although there are ways to fix an old or faulty sealed unit often the problem will just reoccur and you are back to square one.

Our team of glass engineers are highly trained in glass and sealed unit replacement. Getting a quote is easy and if you don’t know your sizes we can send a member of staff out to measure and give you a quote. We don’t employ salesmen, our staff are here to serve you not sell to you. If you want to know more call 01379 854445 now.

What our customers say

Excellent (10/10)

Great service and support.

I had got quotes for Windows & Doors from other companies in Diss and they were all about the same. I called Polytrade who were a little cheaper but the guys were so helpful. Really can't fault them, will use again.

Very helpful staff and good quality building supplies at a very competitive price.
