Very informative

I contacted the company about retrofitting my 70’s bungalow. Ray was very informative and
had lots of advice on how to improve the BER. We have just completed the first stage –
replacing the windows and upgrading the insulation.

Professional quote

I wanted a quote to upgrade my windows before the winter to compare with a company
that I had used previously. I was impressed with the professional quote which included u
values and glazing options. I was making a saving on the old quote so I chose a better heat
loss performing window frame and glazing. Very Happy.

Excellent quality

The Lads arrived on site and had they didn’t remove the old windows until they were sure
the new windows fit! Fantastic service and excellent quality product. They left the place
clean and tidy and I’ve already ordered the doors to be changed.
