10 Replacing old sealed units in double glazed windows. Very happy to recommend CRK
Posted 6 days ago
Once one has discussed requirements with the CRK sales team, the personnel on site are prompt and efficient. The installations have been of high quality and have worn well over the years. CRK installed our double glazing over 20 years ago, and more recently we have renovated the double glazed units at the front of the house replacing with what we think are the latest more thermally efficient and sound proof units that fit into the older frames easily. Also, the company have repaired 3 seized window-locking mechanisms, all now working well. We have found CRK very helpful and recommend them.Verified reviewerJob location: HP310 Quality work

Posted 21 November 2025
We had a new conservatory that required the removal of the old one. From the first visit to the showroom until the final installation day, everything was handled very professionally. The installation team showed up on time each day, without any loud music playing or shouting among themselves. It was a delight to work with CRK, and I wholeheartedly recommend them for all your installation needs.Verified reviewerJob location: HP3
