I would not hesitate in recommending Fortress to anyone.

Many thanks Peter, I am looking forward to the benefits during the winter.

I chose Fortress Doors and Windows to replace my front door following recommendations from family members and have not been disappointed. The service from Peter and his team has been excellent, from initial enquiry, through ordering and installation, to follow up after the job was completed. The actual door looks fantastic and of a very high quality. I would have no hesitation in recommending Peter and his company to other potential clients. thank you.

Had all my windows replaced by Fortress Windows and Doors. Excellent service from start to finish. No hard sell, told Peter Murray what we wanted, took on his professional advice and very pleased with the finished product.. tradesmen very professional and very neat and tidy. They were very helpful and all the rubbish was uplifted straight away. Would recommend to family and friends.
