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.

I had the pleasure of working with Romeo and his team on my kitchen renovation, and I couldn't be happier with the results! From start to finish, his work was great. The kitchen looks fantastic, and they even finished the project ahead of schedule! Romeo and his team were very professional, always on time, and always kept me updated on the progress of the project. They also kept the flat clean and tidy every night, which made it much easier to live in the flat while the project was being done. I highly recommend them to anyone looking for a kitchen renovation!
