Extensions- 4 Aug 2019
Very constructive input throughout the whole process. We were given a clear idea of timescales for every step of the build, what to expect and how they would minimise disruption to our household which was all done effectively as promised. For the beginning he made clear that the process would allow us to still have a family home running (almost) as normal for most of the build, which was really helpful with our young children! Baz would always answer any questions and welcomes feedback. He would be flexible and find ways to work around problems to ensure the design was achieved and did so beyond our expectations. The build was completed to schedule and to a high standard. He would work with you to make sure everything was done properly and around schedules you have with other services if you are using separate glazing or kitchen suppliers as we did. We’re very happy with choosing Smiley building services and would definitely use again. All his staff are friendly, polite and considerate. Friends and family who have seen the work on our house have already asked for Smileys details for their own build work due to the great finish.

Carpentry- 31 May 2017
Was really impressed with these guys. Helped me order the correct garden door and then went to pick up extra bits when the order didn't turn up correctly, for no extra cost and couldn't have been nicer about it, even though it was a pain for them. Really cheerful and helpful - nothing was too much trouble. Would use them again, for sure.

Gerti completely renovated both of our bathrooms, and the final results were absolutely amazing—exactly what we wanted. He was extremely flexible, offered valuable advice for other aspects of our home, and consistently went above and beyond. Having done a lot of work on our house, we can confidently say he is the best builder we’ve worked with. His pricing was very reasonable, and we will definitely use him for future projects.

Extensions- 5 Nov 2016
Leslie carried out the following works: chemical damp injection to walls on rear extension, reroute down-pipe, repair fracture on rear wall, install gutter hedgehog. Hopefully, this will resolve some of the issues we had with damp, a blocked down-pipe and an overflowing gutter. Leslie arrived on time on the first day but was delayed a few hours the next day. However, the work still was done within two days as expected. Thank you!

Jess painted my hall way and put laminate flooring in my lounge. He was prompt and reliable, I was impressed with the how quickly and professionally it was done, he was extremely tidy and put my sofa back so I could still access my lounge in the evenings whilst the work was going on. He was professional at all times, and even helped me with the colors, I would highly recommend him.
