Extensions- 13 Apr 2018
SMD Building and Joinery have just finished building a single storey extension and installing and tiling the new shower room for me, installing french doors and retiling my kitchen floor. Seamus and all his team were always professional, reliable and polite. All work has been completed to a very high standard and everything cleaned and tidied up afterwards. I always found Seamus to be very honest, reliable and easy to discuss the work with and he kept me informed at every stage. I would highly recommend Seamus to anyone and would have no hesitation in asking him to work for me again.

Emergency repair on a flat roof. Got Chris' name from a friend. He came to my house after completing his own work and spent a few hours in the darkness sussing out the problem. When he came off the roof, he saw I was working to put an electric shower in bathroom. He asked if I needed help doing it and had the new shower fitted in minutes. A very pleasant, easy going guy, I have no problems in recommending his work and pleasant demeanour.

Extensions- 8 Nov 2021
Nicky was the only builder to call out and view the site prior to giving a quote, which I’ll add was a fair quote landing in the middle of the 4 we received. Upon meeting Nicky and Darren we knew the job was theirs, they were friendly, approachable but to the point. They worked with us, understanding our budget and plans for the house, and advising us where necessary. Every step of the project they kept us in the loop, they were onsite everyday and the work was clean and tidy, they were very professional dealing with our neighbours also! I will 100% use Nicky, Darren & co again, and would strongly recommend them to others. I can’t fault them in any way! This was the biggest home project we have done to date, and it was They even left us a card and gift, which was a very nice touch!
