Extensions- 30 Apr 2019
What can I say about Steve and his team. Being an ex builder and coming off a not so great experience of a loft extension was cautious in who we chose for our Kitchen extension. I chose SK Builders and their approach to our job was first class and we always had a say in how the job progressed. We had complete trust in Steve and he paid us back in spades. They worked bloody hard in the heat of last summer, always here and slogged their guts out. The work was to an excellent standard and everything was completed, ordered on time. Steve worked around our issues and helped us enormously when it came to the knock through and setting up the kitchen area for us. His team of electricians, carpenters, Paul the plumber and Simon the plasterer were first rate. And all lovely guys. Our job was outstanding and Steve and his team were thoughtful and respectful to our needs. Would easily recommend and have recommended Steve to many people asking who we used. Honestly we could not be happier with the job, which had no major issues at all. It flowed like clockwork. All and all SK Builders should be considered if you are thinking of taking this kind of project, you will not be disappointed with the results.

Decking- 1 Sep 2020
What a great experience we had with Louis. He is honest and gets the job done efficiently with great attention to detail. He did such a good job with our terrace. We had some problems that really needed a professional solution and Louis planned and executed it brilliantly. Instead of looking for excuses for things that could be a problem Louis had a great solution for everything we came across and was positive the whole time. Would highly recommend Louis, we already have him booked in for more jobs.

Highly recommend Kaylum, he ripped out the old sub-floor and fitted a new sub-floor along with new Engineered wood flooring in all of the bedrooms and hallway.

Sean and the team first sorted the foundations and new drainage for our extension. Once that was done, we got them back to give the garden a little makeover — fresh turf down and brand-new fencing in place. Big change for the space! Would have Sean and his team help on future projects. Thanks again!

Extensions- 27 Mar 2019
Luca & Team were very pleasant to work with. They suggested that we go for a bigger extension (3.6 x 8 m), which we eventually did as we had to go for planning permission anyway. Their quotation was reasonable and consistent, and we were impressed with a recent project they did which was a similar layout extension to our plans. They went an extra step always to make the project work for us. They built the rear extension, and then we asked them to add on the finishing (flooring, painting, decorating) and to install the kitchen that we purchased from Wren Kitchens. We were satisfied with their work on our project.
