Carpentry- 10 Aug 2023
you will see I ask for experts in my job posting because my desired outcome of this job was quiet floor as you walk across. I hired LTDinchev and the 2 gentlemen were helpful, pleasant and friendly. The job was completed for the price quoted and in the time specified. my only disappointment is after the job was completed I still had SOME of the same floor noises. so although they work hard on my subfloor I did not get 100% my desired outcome.

Extensions- 5 Sep 2019
The builders did an incredible job refurbishing my house. For my house I wanted to break the internal wall to create a bigger living room and also for them to refurbish the toilet. In the beginning they’ve set a period when everything will be done and they’ve stuck to it so they are trustworthy. Seeing the progress, I could definitely tell that they were working incredibly hard and I know that they have been working long hours to ensure that they manage to finish it within the timeframe that they’ve set. I would definitely recommend them.

Extensions- 1 Jul 2021
Great job done by Naim and his team. He expressed interest in the job as soon as I posted. If it hadn't been for some wet weather the job would have been completed much sooner in the timescale he quoted. There was one small issue some time after the job was completed. I only called Naim once and he arranged a day to come fix it. We're very pleased with the finish, we would give future work to him and also recommend him to friends & family.

What experience do you have with similar extensions in Penge?

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