Our uPVC Window Installation Process

Here's the full process Glassterr follows to install your uPVC windows, from measurement to handover.

How it works

Our installation process starts well before fitting day — with accurate measurement — and ends only when every window is tested and handed over.

The steps

1
We measure each opening on site
2
Windows are fabricated to those measurements
3
Fitting is scheduled around your convenience
4
Old windows are removed cleanly on the day
5
New units are seated true and fixed securely
6
All gaps are sealed against weather and dust
7
Every window's operation is tested
8
The site is cleaned and windows handed over

What this means for you

Controlling the whole process — measure, make, fit — means nothing falls between parties, and the result is windows that fit and seal as they should.
