Extensions- 29 Jul 2026
I rarely leave negative reviews, but I believe in honesty. Paul started out great, very helpful and a quality job up until the finishing. Extremely poor internal 2nd fix carpentry all had to be redone, constantly promised arrival of trades that didn't turn up and all of a sudden, Paul became barely contactable. Then when I asked about building control which Paul had said was taken care of, no answer. I contacted the council to find out no submissions had ever been made, despite being told they have. It's not impossible to get sign off as I don't have evidence of the correct stages being completed. Now, 6 months on, the whole porch has sagged and after an intrusive inspection, half of the timber joists aren't even fixed! The front door was supposedly ordered, 6 months later we were still waiting and endure a winter with makeshift door! Honestly Paul, if you'd talk I'd have an honest conversation because most of you work is quality. My advice to others, avoid!

What experience do you have with similar extensions in Tewkesbury?

Ask to see examples of their previous work, or view examples of their work on MyBuilder. Ideally projects similar to yours in scale and design. This helps you assess the Tewkesbury extension builder’s ability to deliver a result that meets your expectations.
