I have now used Maxwells on numerous occasions, both for improvements and emergencies. They respond promptly and professionally whatever the situation. I could not fault them on anything. My daughter lost ridge tiles in recent storms and Graham resolved the problem same day at a competitive price. I recommend without reservation

We have just used Maxwell and Son for extensive work for exterior and interior work for many various work tasks over the past weeks and they have been excellent with all work completed beautifully and top class and all within good price . Also we were so pleased with the communication with Graham, his wife and work teams at all times with no delays, prompt work timing etc and advice from them. Planning with them was excellent and no have the house exactly as we had hoped to be. A huge thank you and we would recommend to everyone considering any work to be carried out to contact Graham as your first

Graham & his team built an extension to our bungalow in 2000. We were (& still are) very pleased with the quality of work involved. Since then, we have been very impressed with the way he has come to our aid with any job (large or small) we have asked him to undertake. From constructing most attractive raised beds & re-building a collapsed pergola (without harming the climbing plants) in the garden, to plumbing jobs & solving any number of electrical problems in & around the house. He & his team are efficient, helpful & above all - considerate & hard working. My husband & I highly recommend
