First floor extension on existing ground floor extension to create master bedroom with ensuite. Also to fit some extra new windows on existing house, also new guttering, facias and sofits on entire property. I cannot fault Dean and his team one bit. From the quality of their work to their cleanliness it was always exemplary. I've recommended Dean and team to countless clients and some family members who needed a reliable builder and have only had positive feed back since. I'll be using Dean and team again on my next project 100%.

Damp Proofing- 12 Jan 2016
Tony and his team were superb. They assessed the work, drew up clear plans so I understood what the job entailed and completed the interior work to a very high standard. Every day they swept and mopped to reduce my workload and for the first time in my experience of builders, every last scrap of rubble was removed. A very happy customer; cannot recommend them highly enough.

Conversions - General- 7 Feb 2025
Stephen and his Team were utterly professional, their work was faultless and we couldn't be happy with the job. We had a wall removed in the kitchen which needed a support putting in, and a wall removed in the bathroom and a doorway sealed up. Right from my initial contact with Stephen we got got a good feeling, his quote was the most competitive but we had already decided to go with Stephen anyway as his experience, expertise and integrity were obvious as talked us through the job and what would be required. Their work was fast and to a great standard. We were very impressed with how clean Stephen and his Team managed to keep the house throughout all the work (especially as we have black mortar in the walls), they cleaned up throughly every evening and it made life so much easier on us.

I HIRED ANDY TO RENDER SIDE & BACK OF MY HOUSE. THE PRICE WAS FAIR . ALL STARTED WELL , IS LABOUR DAVE WAS VERY HARD WORKING DOING MOST OF THE WORK. WHEN ANDY TURNED UP TO PUT THE COATS OF RENDER ON THE BACK , THERE WAS AFEW MISSES & A WAVE GOING FROM ON END TO THE OTHER. WHEN HE DONE SIDE WALL AGAIN THERE WAS MISSES , NOT ONLY THAT BUT THROUGH OUT HE LEFT THE PLACE UNTIDY . DID NOT PUT THE DOWN PIPE BACK ,DID NOT REPLACED THE BROCKEN TILES , DID NOT REPLACE BROCKEN STEP, DID NOT PUT THIRD COAT ONE LIKE HE SAID HE WOULD . AFTER TELLING ANDY ABOUT ALL THE SAID ABOVE, IS REPLY WAS IT WILL COST ME TO PUT IT RIGHT. SO MUCH FOR THE AGREED PRICE FOR THE WORK UNDERTAKEN. NOT VERY HAPPY BECAUSE IT COST ME MORE MONEY TO GET A NOTHER BUILDER IN TO FIX IS MESS , WOULD NOT RECOMMED HIM.

Landscaping- 21 Apr 2019
Very happy with completed job. Took a little longer than expected due to size of task. Felt comfortable with leaving Jason Johnathon and crew to complete when called away from home for couple days. Time discussing details before hand ensured team were clear with what we wanted. Workforce was punctual, courteous ,professional and helpful with suggestions! Would definitely call on them again and have no hesitation in recommending.
