Landscaping- 20 Jun 2024
From even before the job started I knew I’d made the right choice. The communication was truly 10/10, not too common nowadays. After 2 long days of hard graft in the summer sun the place looks a thousand times better, we’re dead happy and have met two great guys in the process 👍

Plastering- 4 Apr 2019
Petre and his colleague arrived promptly and worked very fast and efficiently. They fitted a new plasterboard ceiling and plastered the whole kitchen in one day. They were polite and tidy. Their work is to a very high standard and I will definitely be using them again.

Bathroom Fitting- 2 Mar 2026
I can’t recommend him highly enough, in just three days, he identified and resolved my bathroom leak that could easily have become a much bigger issue. He took the time to thoroughly investigate where the water was coming from, clearly explained his findings and advised on the most sensible next steps before carrying out the work. From start to finish, his work ethic was exceptional. He arrived promptly at 8am every day and worked through until 6:00pm without a single complaint, no matter how demanding or time-consuming the job became. His efficiency was impressive but what stood out even more was the quality of the finish - the bathroom now looks brand new again. Professional, hardworking and meticulous in his standards, he delivered outstanding results in a very short timeframe. I wouldn’t hesitate to use him again or recommend him to anyone needing reliable, high-quality building work

Latest review:
Works consisted of hip to gable loft conversion under permitted development and a refurbishment of the first floor of a semi-detached house into a four bedroom/bathroom layout, including new windows, balconies, wiring and plumbing as well as sound proofing the walls. With 100m2 of works this was my first introduction to a major building project and I was worried by the horror stories I have heard about builders. From the outset Monika set my mind at rest, listening to what I wanted, making helpful suggestions, offering tips for instance on how to save on the scaffolding and always asking me when choices needed to be made. She took the trouble to ensure that I knew what was happening, with daily photos of progress without the need for me to climb scaffolding. I was working to a tight timescale and budget, which Monika understood, and even having accommodated a number of changes including some additions, the project came in on time and on budget. All of the workers on the site were very professional and the quality of the work and the attention to detail was exceptional. I have no hesitation in recommending Monika and her team - I went into this project apprehensive and not sure what to expect; thanks to Monika, I came out the other side delighted by and looking forward to working with her and her team again to renovate my ground floor.

What experience do you have with similar extensions in Hampstead?

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