Testimonials

What our clients says

  • We used Chris and his team to build a 40 square metre single story extension. Despite encountering problems with soil conditions when putting in foundations Cris and his team quickly found a solution that satisfied building control. Very pleased with the finished result. Would highly recommend.

  • After i spoke to Chris Baker the owner at Earthstone about the renovation project for the whole of my house i was convinced he was the right man for the job and after the various quotes i had from other builders his was very competitive. And now the job is completed i can say throughout the process Chris and his team were fantastic

  • We couldn’t be happier with the service we’ve received from Chris and his team. They’ve worked tirelessly in all weathers to keep everything on track and meet our finish date, always with a positive attitude. Nothing has been too much trouble, and they’ve regularly gone above and beyond to help us with extras. What really stood out was their honesty and reliability

  • Chris was brilliant from day one. I had an extension above my garage & study creating 2 bedrooms and a bathroom. He was easy to communicate with, really helpful and very reassuring. I hadn’t embarked upon anything this big or expensive before and Chris helped me at different stages offering to pick up showers/ toilet/ vanity unit etc.
