Heath Windows replaced 6 old failed units and door at the back of the house with modern ones and were chosen on the basis of internet reviews , (two other quotations were also sought for comparison). Not the cheapest but in the event the best value for money and one of my better decisions. Sales side not pushy but helpful and the advice given was good and accepted. Front door was apparently installed 10years ago incorrectly by another company but Heath Windows advised it wasn't necessary to replace it and they corrected the faults and it now fits properly. No charge was made for this.
The Install was very efficient, no mess and great care taken with the installation. An outstanding company that I wish the other trades, with the exception of the central heating installer, would copy.
A company I can recommend without hesitation.
