Electrical- 30 Oct 2025
Since Steve and his team came on board, the progress on site has improved significantly. Their professionalism, efficiency, and strong work ethic have made a real difference. Steve provided a very fair and reasonable quote, and his approach to the job has been both proactive and solution-focused. Even though the work is still in progress, it’s clear that Steve’s expertise and leadership are helping to move things forward faster and more smoothly than before. His attention to detail and willingness to go the extra mile have been greatly appreciated. I’m very pleased with the results so far and have full confidence that the finished work will be of a high standard. I highly recommend Steve and his team for any electrical work, they’re reliable, skilled, and a pleasure to work with.

Groundwork & Foundations- 7 Nov 2024
From start to finish, Bogdan and his team were exceptional. After dealing with a previous builder who caused numerous delays, I found SBG Services. Bogdan came by the same day to assess the job and impressed me with his extensive knowledge. Given my tight schedule, he got to work immediately. I’ve never seen a builder work as hard as his team; they labored tirelessly from morning to night to ensure the project was completed promptly without compromising quality. Every trade I've had since has commented on their attention to detail. In just three weeks, they completed two extensions and transformed my garden. I will definitely be calling Bogdan back to handle my front garden early next spring.

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

I have my rear house extension completed and a brand new kitchen installed by this firm. The project went brilliantly from start to finish despite the bad weather. The workers always turn up on time, rain or shine. Mr Ram and his team were pleasant to work with and they were always willing to listen to suggestions for improvement. They have eye for details making sure the works are completed to the highest standard without compromising the budget. I am pleased with the work and would highly recommend this firm unreservedly.

Tiling- 6 Oct 2022
We are beyond shocked and disgusted by his awful behaviour. Initially, he acted professional and trustworthy, but he turned out to be exactly the opposite. On the 8th of July, he promised "3-5 working days" instead he pulled us along for two months of unbearable stress and waste of time because he kept on taking other jobs instead of doing ours. He wasted all of July as we had to meet him four times to finalize the design that he kept on rejecting until we agreed on the easiest option for him. He dragged out removing tiles and levelling 10 steps all of August, working 6 hours in total and leaving a job that is so appalling that it needs to be completely redone. He postponed the tiles' order for a month despite assuring us all August that he had done it in July; after numerous complaints, he sent the tiles' invoice, dated 31st of August. He gave us dozens of appointments but never came nor had the decency to cancel, despite dozens of calls, emails and texts, causing significant disruptions and loss to our life and work commitments. We asked him to reimburse the cost of the tiles and materials he didn't provide and for the work he didn't do, but he ignored our emails. We have removed him from the job and are reporting him to the relevant authorities.

Great service and value for money. We commissioned Paul to build a garden office. The job was completed in less time than originally expected and the quality of the workmanship was excellent. I have no hesitation in recommending Paul and we have already passed his details on to a neighbour who wants a garden studio built. We will also hopefully be using Paul's services again in the future on a loft conversion.

What experience do you have with similar extensions in Borehamwood?

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