I have just had my windows and doors installed by Callum Fraser, I would highly recommend this company Having just had my windows and doors installed by Callum Fraser, I am very happy with the whole process from the initial consultation right through to the fitting. No pushy salesmen, friendly and honest. The installation went smoothly, they have completed the job quickly and it looks great. They cleaned up afterwards. I would not hesitate to recommend this company to anyone.

Don't let these people over your front … Don't let these people over your front door. Didn't improve my home but left it in a worse state than it started. The affable Fraser turns up and promises you the earth but can't deliver as he doesn't know what he's talking about. It's all an act. And there's a reason he only deals in cash. Central heating still not properly installed from September and my home was an absolute mess when they left. We had to replace floor in living room as radiator not installed properly and left with a leak. Said they'd be back to finish but low and behold, they didn't return. No answer on the phone. Who knew! Please stay well away from this "company'.

Professional advice, attractive pricing, very good service Dealt with Martin, knowledgeable pleasant person and humble salesman. No pressure, no bs, just chat to a guy who is happy to help and ready to do his best.Good price so in the end we decided to replace all the windows and doors. Great delivery of service. The fitters (father and son) knew what they were doing so smooth pain-free experience. I am happy to pay and can recommend them.
