Work we're proud to put our name to

Fantastic experience from start to finish. The team was incredibly fast, helpful and clearly took real pride in their work. The windows were installed with great care, and they even proactively swapped out a few that didn't meet their own high standards. Michael kept us in the loop every step of the process and made sure everything was completed to the highest standard. Highly recommend!

Fantastic service, a pleasure to deal with from the initial measuring up to the delivery of the large window I had installed. Work and installation was perfect. Very neat and tidy after, no mess. O'Sullivan did my aunt's house and I highly recommend them. When I'm getting the rest of the house done, there is nobody else I will be calling on.

I chose Paddy to install my triple glazing based on his excellent reputation, and I was not disappointed. The quote was fast and accurate, the price was competitive, and Paddy's guidance on my options was invaluable. Delivery time was perfect and his workers were a joy to have in our home. If you're after windows and doors, look no further.

I had my windows all replaced and a new front door fitted by Paddy and his team. They were excellent to deal with and did a fantastic quality job. A pleasure to deal with, would highly recommend.

First class service from O'Sullivan Glazing. We got a new front door which I am delighted with. Very quick and clean. The two men who work for Paddy were polite and helpful. I can't recommend them enough. Thank you.

O'Sullivan Glazing are one of the best companies to deal with. Excellent service and no problems when following up any snags that may occur. I highly recommend them. Paddy, Michael and the crew, thanks for great service.

Michael was amazing! Came to just have a look at a leaky window. Stayed and fixed it, then fixed more! Went above and beyond. Thanks again!
