Extensions- 9 Mar 2018
Kenny has just finished building a porch at my address. From the beginning, Kenny has been excellent with regards to providing advice, arranging the job to suit us and providing a very competitive and reasonable quote. Whilst on site, Kenny arrived early, was always extremely polite and the finished job was even better than we imagined it would be. On a scale of 1-10 we would honestly give Kenny an 11 and will definitely use his company again. Would definitely recommend him to others.

Carpentry- 8 Aug 2023
Chris was quick to respond to my post and attended only a couple of days later to quote. The quote was very reasonable and I chose him for the job, based on his competitive quote, his evidenced standard of work and general personality. Chris has kept true to his word throughout the works needed (new door frames, all skirting boards - porch and living room, new floor in porch and new front door). He has unbelievable pride in his own workmanship and is incredibly trustworthy & reliable. I live in a very old property, that doesn't have a straight wall/floor in it - Chris' knowledge shone through with dealing with what may seem small to those of us untrained - he used all his 'tricks' to ensure everything was fully secure and gap free, everywhere (including his personal pride). I was able to have very honest conversations throughout, regarding the work and also additional costs to the quote (n.b. this was not significantly more, but absolutely reasonable due to additional materials) and his expectations were never unrealistic or beyond my budget, nor the conversations difficult or confrontational. I genuinely can't praise or sing Chris enough. His quality of workmanship, personal pride and outstanding personable style is a breath of fresh air. My final comment would be is that he is to be fully trusted, both professionally & personally and he will deliver you an outstanding job, whilst keeping you informed throughout, in an honest and open style. I'll recommend 100%

My Mum is soo pleased with the completed job, Tommy has made good of a previous bad job by somebody that I hired off of this site.
