Just had a draughty 25 year old upvc door replaced by this company. The unit was fitted a month after the original estimated time which is understandable with the current Covid restrictions. Very pleased with the finished result after they were recommended by a neighbour who recently had a large renovation completed. I was particularly pleased with the attention to detail in making good the exterior rough cast rendering to match the existing wall. When painted I think it will be difficult to tell that it’s a newly installed unit. Not the cheapest but worth the extra for a sound solid result.
