McDermott windows were recommended to me and I am so glad I found them as a company! I have so far only had one bay window fitted by the company but the rest of the house is also being done in the coming weeks. Stephen is brilliant at his job and also keeps you informed regarding your order. Stephen had a really nice colleague with him called Jordan who worked so hard in an extremely cold environment!
My 6 new bay windows look beautiful and really change the look of my house. The windows came in cheaper than other quotes and they are extremely high quality. I would highly recommend McDermott windows

We can not recommend McDermott Windows highly enough. We have had new windows, doors and fascia on our property, and the service we have received is impeccable. Stephen and Emma (and Jordan) were brilliant throughout the project keeping us updated at all times. The finished job looks great, and very happy. If you need windows and doors, contact McDermott Windows....you will not be disappointed.

Would definitely recommend McDermott Windows. We have had all new windows and doors and cannot fault them at all. From design to installation and aftercare, everything has been second to none. Queries are responded efficiently, installation is timely and tidy and a huge effort is made to ensure the final look is perfect. Cant thank Emma, Stephen and the team enough.
