Painting & Decorating- 1 Nov 2025
These men have an idea of moulding installation but not to a professional standard. They did my job half-hazardly without professional finishing. Moulding full of gaps and rough eges, they started to paint it without filling or sanding. Moulding unfinished. Walking all in the house on a very cleaned carpet withheavily dirty shoes. Leaving the whole place they walked through very dirty and not proper cleaning after work. Insufficient material and equipment.?unprepared. Many more. Don't pick up a job in a rush , if you picked up a job, you should create time to finish it before scheduling for another. Or pick up a different date to come and finish what you have started. it is as simple as that. You are making me angry and disappointed because you made me feel like my job which i am paying you for, was less important than anyone else's. I was too nice and lenient to have payed you without involving the law.

Extensions- 13 Apr 2024
Jake was a pleasure to work with from start to finish. He maintains extremely high standards for his own work but also the other tradesmen he works with. It wasn't a straightforward extension and we always felt confident and reassured by Jake that everything would work out. And it did Despite some pretty brutal weather this winter Jake was here everyday to keep the project moving forward. Aside from the obvious high quality work he does, what stands out most for me is Jake's communication. He would always respond to texts or calls and we always felt we knew where we stood with the build and that the inevitable little problems were in safe hands. His quote was very competitive and the payment schedule was very manageable and straightforward. We have a young family and Jake and the lads became part of that family for the duration of the build. Our kids still ask when he is coming around. He was great with them. We are delighted with the work. Wouldn't hesitate in recommending.

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 Birmingham extension builder’s ability to deliver a result that meets your expectations.
