10 Great garage conversion
Posted 22 February
Job location: SG1I have used Mason a couple of times for jobs around the house. The main one was a garage conversion and new kitchen entrance. He personal worked out how to best meet my requirements and did a great job of hanging new doors and making the floor ready for tiles. Installed a new partition to make a smaller garage and expand the kitchen area. Really great work and super impressed with his professionalism and dedication to getting the job done right.10 Expert service, very professional and friendly

Mason was very helpful and professional, it took him no time at all to build me some storage boxes for my garden tools and he was a pleasure to deal with. He made sure all of my needs were met and that I was happy with his work at each step of the way. I would highly recommend him for all your carpentry needs and I have already booked him in to do more jobs around our home. A* service!!!Verified reviewerJob location: SG310 Highly recommended Carpenter
