Impressive and trustworthy Company Callum Fraser UPVC are at the top of their game. They provided us with an excellent service and excellent product. I don't normally do reviews but I thought these guys were worth taking the time to give a review. I would not hesitate in recommending them.

Dreadful company Dreadful company. Avoid at all costs.

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'.
