Gelu is hard working and dependent guy, will not fuss about the job like many do, but will crack on with it. Stayed late to finish it at many times. I am quite happy with the finish and work. shower fit, washbasin, toilet, tiling all done to my satisfaction. After seeing the work I asked him to do more like kitchen cabinets and skirtings.

Extensions- 18 Sep 2019
To start off with the job went reasonably well - we were happy with the workers and the progress. but when we neared completion the work slowed up we waited 3 months for a response from Jordan. we had an issue where his plasterer hid the plumbing access in the wall. - This cost us £500 to sort and re-decorate so we came to an agreement that this was fine and at the time i presumed that Jordan was going to sort out the building control. so we then chased and chased but obviously since he had his money he wasn't interested he answered the phone and hung up. so we called building control and there are 2 small bits to fix which are all due to his work not being up to scratch. obviously i will be paying out for this - so please be careful when using him and dont pay him until you have all of the documents as he will not resolve any issues after being paid. i have had 2 previous building projects and this was by far the worst experience going. avoid dont use him thanks

What to ask a Shefford extension builder before hiring?

What experience do you have with similar extensions in Shefford?

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