Cassidy Glazing & Locks

Really pleased with the work carried out by Cassidy Glazing. Luke and Gary did a great job replacing the three blown sealed units in our second bedroom window, installing trickle vents to help with condensation, and adjusting the balcony door.

They were professional, friendly, punctual, and left everything clean and tidy afterwards. The work was completed to a high standard and the pricing was fair too.

Would definitely recommend Cassidy Glazing and would happily use them again in the future.

I moved into my new home and need a catflap fitted into my double glazed patio door. It was an added bonus that Cassidy Glazing also does locks. The glass was installed a week later and the patio doors, that had been a bit tricky to close and were catching, was fixed as well as the catflap installed. They also changed the locks on my front door. Really reasonably priced and lovely people to deal with. I highly recommend their services. From start to finish, a pleasure to do business with.

I used cassidy for new French Windows with a cat flap in them.

Very pleased with both the quality of the doors and professionalism of the fitters.

James did a survey and gave me a quote for the required works on a property I'm in the process for buying - all free of charge. Gave me good confidence going forward with the purchase. Will likely be using them more in the future

We had a 5 star treatment from the people at Cassidy Glazing and Locks. Our upstairs windows in the house we bought had multiple window panels that needed replacements. The two men who came out to measure everything up were very efficient and friendly and the firm was back with an estimate and offer of times that the work could be done. The team of 2 came out to install the replacement glass and again the men were friendly, answered any questions I had and the job was completed well and on time. I am happy to recommend this business.
