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.

Agim and his team were great - communicated what they would do at each stage, the timing, materials needed etc., no major surprises. The building is quite old and wonky in places so they had to work with that and the finished result looks great. Very happy and have would recommend Agim again!

Simon & his team have done a rear extension & loft conversion for us. The work has been carried out to a high standard and was completed ahead of schedule. Simon has been professional throughout and we had a very positive working relationship. He gave us good advice & suggestions throughout the project which improved on the plans from our architect. He also listened to our ideas and was always willing to add in extra bespoke details, for example, a bar in our kitchen based off a Pinterest picture. His team are all polite & hard working. Overall a very positive experience!

Kitchen Fitting- 24 Oct 2016
Kris, Gustav and their team have been absolutely amazing, cannot praise them enough. First of all - the job ended up being a lot larger than initially thought- as decided to replace old ceilings and flooring, walls -everything was uneven to start with. So took everything back to 'bare bones' and pretty much built it up again as a new house. New electrics, water pipes, completely new kitchen and bathroom. I really appreciate they were very straightforward with the estimated costs from the beginning - it did run slightly over budget but nothing too bad as had some contingency funds prepared. I would have hated to be quoted one price then half way through the project to discover it escalates out of control. Thankfully they are really honest and reliable. They were always easy to reach and replied any question I might have had in a timely manner. This was particularly important to me as I was between uk and us at the time so couln't be 'looking over their shoulder' so to speak. Last but not least the finish and quality of works is absolutely amazing! They couldn't have paid more attention to every little detail if it was their own home. For instance I remember last day of work when they were tidying up Gustav came back to put up door stoppers for me, completely on his own initiative. It's just a little touch but goes to show the dedication they've put into the project and care about the finished product.

Bathroom Fitting- 4 Jul 2026
Fred is not only friendly but is also a great tiler / plumber. In the end we decided to redo the whole bathroom. Fred advised throughout, remained available for questions and was able to fit us in quickly. He did a great job tiling and re fitting our unusual sunken bath which involved going into a crawl space others had refused to go into. His quote was very reasonable compared to others we had gotten. We would highly recommend

I was very pleased with this company so much so that they are starting a new job for me November 15. The building firms carried out a full loft conversion for me installing bathroom, brickwork, joinery, plastering, Roofing and installation of windows and double glazed doors. I have high standards and want everything to be completed in the same way, the workmen respected my home and always left if clean. My main contact was with the owner of the company Dwight Lynch, he was very flexible and Nothing was too much for him to do. He has an attitude which I like in a builder "customer not always right but must be happy" he provided me with ideas along the way and where things did not go to plan due to my own instructions he worked around the issue and provided suitable alternative options. I was very happy with the pricing of the job and feel that certainly I would recommend him and also I would use him again. He and his workmen were all trust worthy and I gave them keys to my house to carry-out work whilst I went on holiday. I had no concerns when I came back everything was as I left it.
