Ervins done a great job. The wardrobe is now repaired and sturdy. In fact it is much more solid than it was before. He was also able to attend at short notice as everything had been taken out of the wardrobe so needed the job done urgently. Would not hesitate to use him again.

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.

Mohsen went above and beyond with our kitchen face lift. He did exactly as asked, to a very professional standard. Mohsen is very hard working, has high standards and was reliable. He also suggested ways to improve our kitchen, and corrected some previous poor work from other builders! We love the job and will definitely use Mohsen and his team again for future work.

Sean did a full refurbishment on our house. He is the most organised and customer friendly builder I have ever used. From start to finish there was a plan of action and then a great group of qualified tradesman to execute. Like every refurbishment, we asked for changes and he always made us feel like the extras were no problem. I have no hesitation in recommending CG Carpentry. They are now our go to builders and in our next move he will be the first person I call.
