We recently had an extension built at our property and Lee and Rob were amazing throughout the build. The price was better than all the other quotes we received, they were thorough, professional and personable during the build and finished the extension to a high standard. All the other trades they used were at an equal standard and it was a pleasure to have a builder that cared as much about our property as we do.

Lee was the only local builder I found willing to take on the job. His calm and expert knowledge was very reassuring. He co-ordinated his team seamlessly to get the work done and was always reliable and contactable until the work was completed. Can't recommend enough.

Wow! We got in touch with JB HOUSE to quote on extending our home and the service we received was second to none. They were able to provide drawings, arrange the necessary planning application and building regulations and the complete build itself! The extension to our home is fantastic, we cannot believe the difference it has made and can't recommend Lee and his team highly enough. If you are looking to have works carried out on your home then try JB HOUSE they were clean and tidy, courteous and considerate during the works. An extremely professional and reputable building and roofing service
