After shopping around, we allowed ourselves to be convinced that Cambridge would be able to deliver windows of good quality and that they would not only perform a quality installation but also stand behind it with a good warranty.... On all counts we were sadly mistaken... The installation was done in a haphazard fashion from the outset with the installers cutting massive gaps of drywall around the window frames, then filling it with foam and slapping on extremely wide trim around it to hide their mess, and used the cheapest grade MDF trims where there had been high quality solid wood trim before... Explanation? Drywall repair was not included in the price; they didn't seem to have an issue including unnecessary damage in the price... although they were good enough to cover the installers coming back to correct 2 windows they installed in inverted locations.
Less than two years into a 25 year warranty I contacted the company to request service for one of the Windows which had obviously lost its seal, given the massive amount of condensation between the panes of glass... Several calls went unanswered before we finally decided to simply budget to have the window replaced by a more competent company next year...
At least we only let them touch one floor and not all 3...
Definitely, absolutely, unequivocally, WOULD NOT RECOMMEND.!
