Highlights
"Jonathan quickly identified and fixed the fault. He’s prompt, friendly, and competitively priced. I’ve used him before to fix issues with other doors."
"Twice now I’ve used Diamond locksmiths and windows and cannot recommend Jon enough - very professional, prompt and extremely knowledgable- great job done both times - 1st was replacement and repair of door panel and then 2nd was a brand new replacement of glass patio door along with cat flap fitting. Both times he exceeded expectations and did an amazing job. Thankyou Jon"
"Jonathan did a great job to repair a few windows that either cannot be opened or have loose handles. The job has been completed in high quality with a very reasonable price."
