When you choose First Glaze you will receive a first class, personal service with one point of contact from start to finish. The tailored service that I provide allows you to benefit from my experience and knowledge. I am always happy to offer technical advice.

I don’t just replace or repair windows and doors, I go the extra mile to discover what caused the issue in the first instance to ensure a satisfactory resolution. I provide a customer service that I would expect to receive myself.

Why Buy New When a Repair Will Do?

At First Glaze, we put integrity and honesty above all else. We’ll never try to push a product onto you or try to upsell you into unnecessary installations.

As Steve likes to say, “Why buy new when a repair will do?” Instead of insisting on unnecessary upgrades, we’ll repair your current double glazing so it lasts as long as it can before you need to completely replace the unit. For more information on our double glazing repairs, give us a call or contact us through our online contact form.

Here's What Our Customers Have To Say

Wendy Smith

Steve did a great job replacing glass in bathroom windows at a great price as did not need whole windows replacing. He even sorted out my back door which kept sticking.

Angela Maher

A fantastic service from Jake and Kyran. They came out to fix a problem that was due to another company. Would highly recommend them.

Sweleni Costa

Amazing! My balcony door was bent at the bottom and didn’t fully close. I called First glaze and on the same day the guys came over to have a look. Thought I was gonna have to change the whole door, but rather than just selling me a new door Steve gave me the option to fix the bend and save some money. He’s done the whole thing on the same day and I was extremely happy about the final result. The guys were so professional and friendly, I would definitely recommend their service to anyone and call them again if I ever need it.


I'm really pleased with the work Steve did and would definitely recommend him and First Glaze. Steve's communication was very good, informing me of parts availability and arranging a fitting date. His workmanship is also very good too as Steve used quality, reliable parts that look smart and function perfectly. Thanks again.
