Extensions- 2 Oct 2024
He did the extension well, brick work is good, rendering on front of house good, terrace and wall with the neighbours good ,toilet under the stairs good, dividing wall in the living room with sliding doors good, kitchen installed good. Fence wall in front of house good brick work wrong bricks but it’s ok. Herringbone parchet wrong with gaps and lifted, rendering on the side of house wrong with marks, the new boiler took 2 months to make it work and the radiators still don’t work. Electrical work bad, after bringing another engineer to check we discovered at the boiler live cut cables that were loose and veri dangerous. Took 4 months to finish job we waited one month for the plumber who either way did a bad job. Laurentiu did not finish the job because of plumbing and rendering, and we ended in bad terms, he left us money to compensate for it. I would recommend him for extensions and any brick work, he needs to improve in pluming, electrical, flooring and rendering.

First class job by Kieren and the guys. They did 2 garden walls, 2 planters and a bbq and sink area for us, which included some not so standard details. They seemed as excited by the job as we were and its always great to have someone feel passion and pride in what they do. Reliable and nice guys too. We're so pleased with what they've done and would 100% recommend.

Extensions- 2 Aug 2023
JLita construction were hired after a competitive quote was agreed to carry out work on my kitchen extension project last year. Prompt and dependable Jetmir’s team worked productive long hours with a clear understanding of my wants and requirements. Where it was possible to accommodate they did. Any remedial work was quickly picked up and completed in good time to the required specifications. After completion of work each day, the space was swept and tidied and the space made as usable as possible. I am extremely happy with the work carried out and the attention to detail applied by Jetmir and his team and would, (and have already) happily recommend JLita Construction for any building works. More than satisfied. Many thanks Jetmir and team. Scott

Groundwork & Foundations- 5 Aug 2024
Des and Steve did an outstanding job digging for the foundation and pouring the concrete. They were professional, very tidy, and friendly throughout the process. I also want to express my appreciation for their plumber, Tony, who did a great job redoing the connection to the old cast iron water supply pipe and moving the stopcock. Their combined efforts were impressive and much appreciated. Now waiting for them to carry on with thd brick work.

Extensions- 6 Mar 2023
So glad we found Paul to conduct our house extension. Whilst work is still ongoing I have found Paul to be polite, considerate, and very experienced in the building trade, a big plus point is his costs and reliability. His knowledge is invaluable and has given us lots of ideas to consider during the build. Currently the team of builders conducting works to date have been lovely to be around and brickwork is amazing! Although still some way to go, looking forward to the next few months and the finished job.

What experience do you have with similar extensions in Chesham?

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