Bathroom Fitting- 2 Mar 2026
I can’t recommend him highly enough, in just three days, he identified and resolved my bathroom leak that could easily have become a much bigger issue. He took the time to thoroughly investigate where the water was coming from, clearly explained his findings and advised on the most sensible next steps before carrying out the work. From start to finish, his work ethic was exceptional. He arrived promptly at 8am every day and worked through until 6:00pm without a single complaint, no matter how demanding or time-consuming the job became. His efficiency was impressive but what stood out even more was the quality of the finish - the bathroom now looks brand new again. Professional, hardworking and meticulous in his standards, he delivered outstanding results in a very short timeframe. I wouldn’t hesitate to use him again or recommend him to anyone needing reliable, high-quality building work

Extensions- 14 Mar 2024
We had the best experience with Paul and team from the beginning and would 100% recommend him for any job. From the beginning the communication was great, he gave a quote and then didn't chase us for an answer as there was a couple months in between before we confirmed. Once confirmed, he booked a date in. Tim and James turned up at 7.45am every morning, lovely guys who got on with the job and were always polite and friendly. They were also extremely clean and tied up everything as it was before they left. So happy with the finished job and definitely use again for any further work. Thanks Paul, Tim and James!

Bricklaying- 16 Dec 2021
I'm very pleased with the repair that Jack carried out on my garden wall. Even though it was a small job he took the time to do it properly and ensured the bricks that had fallen down were put back straight. It started raining a little on the day causing the cement to run. Jack returned a couple of days later to tidy it up like he said he would. On inspecting the wall today I noticed that the cement on the bricks on the inside of the wall did not look as neat as how it looks on the outside of the wall. Maybe the rain caused the cement to run too much, I don't know. Overall I am pleased though and I've asked Jack to quote for another job.
