Bathroom Fitting- 14 Apr 2023
Jordan and his team did a first class job of renovating our small cloakroom. Punctual clean and professional workers. We are both elderly and it was quite a daunting prospect inviting workmen into our home to have this refurbishment carried out. Both we and our home were treated with the greatest respect at all times. We felt we were in safe hands and cannot thank him and his team enough for all the help they gave us . Would have absolutely no hesitation in recommending him to anyone. Thanks again guys … you did a great job here .
