Posted 07 February
Dan was at my house within a few hours of me talking to him, he is the most politest of people I have come into contact with, he was very professional and helpful. Well done Dan. Highly recommended to everyone who requires work done.Verified reviewerJob location: CM1310 Misted Double Glazing Repair

Gave Lockseal a call to provide a quote for a number of misted double glazing units. Dan arrived on time and provided a very competitive quote which I decided to go with. He then arrived on time and did a great job, leaving me with mist-free windows which made me wonder why I had not got them replaced sooner. I would definitely hire Dan again for an glazing work and highly recommend himVerified reviewerJob location: SS15- DDrew G
10 Conservatory & Broken lock on bedroom window..
Posted 17 September 2025
Job location: SS14Just to further expand on the work that Daniel did for me; he came to fix various leaks in the conservatory that were happening. Since he did the job a couple of weeks ago, it hadn’t rained much. Now it has rained quite a lot, I can see he has rectified the problem. He also was able to fix a lock on the bedroom window, rather than replacing it. I definitely recommend his services. 10 Reliable & Fair.

Daniel visited within 3 hours of contacting him and quickly resolved the problem. I have used his services once before, as has my daughter at her house. He has been reliable and competent in the work done.Verified reviewerJob location: RM1110 Bedroom and living room window repair
