    Dave built a garden room for us . It turned out better than we could have ever imagined . We also landscaped our garden . It has gone from being a complete eyesore to being a beautiful addition to our home and a great space for our family . He's friendly , professional and extremely good at what he does . Would recommend .

    We were recommended to use Dave by a family member and we couldn’t be happier with the work carried out. Everything thing was done to a very high standard. We would 100% use Dave for future worksnand would be confident in recommending him to friends and family.

  • En-suite installation and waste pipe and draining installation to main drain.

    10Verified Review

    Dave did a great job in getting an en-suite installed in the room above our garage. A trench was dug and the waste pipe was installed to the main drain. The enclosure for the en-suite was installed, and he organised the plumbing, electrical work, and plastering that needed doing. All the guys involved finished their work to a high standard, and within budget. Thanks again ??

  • Extension

    10Verified Review

    We took a chance on Dave, we didnt know him just a facebook recommendation from someone we didnt know either ! What a talented,hardworking,diligent young man. He basically built the complete extension on his own as he was continually let down by labourers. Dave couldnt do enough for us, consulted us and explained the process and helped with building regs along the way. His reputation is built on people being 100% satisfied and we are truly satisfied! We couldnt have picked a better man for the job. Absolutely over the moon ! Thank you so much Dave. Youve become a friend.

  • Cladding and Rendering


    David and his team worked extremely hard every day they were at my home. It took a day longer than expected due to him being rained off but he informed me he wasn't able to come. After the end of each day, he would explain exactly what he had done and would be doing the following day. He worked above and beyond my expectation and even removed my kitchen door simply because I mentioned I was thinking of removing it. I'd describe David as a perfectionist who loves his job! His quote was very reasonable and I've asked him to quote a few other jobs. Id happily recommend David to my family and friends.
