Plastering- 11 Apr 2026
Absolutely thrilled with the work carried out by Harman. The skimming has been completed to an exceptionally high standard - the finish is incredibly smooth and completely seamless. Harman and his colleague were professional throughout: tidy, courteous, and very polite. They took great care to properly protect and cover the surrounding areas, leaving everything clean and intact once the job was done. What really stood out is their attention to detail and commitment to getting everything perfect - even offering to return for any final finishing touches if needed. I honestly couldn’t recommend them highly enough. Brilliant job from start to finish.

Extensions- 15 Oct 2020
DPS were superb from start to finish. They were hired to build a single storey rear extension in North London including a new kitchen and bathroom fit. I met Ralph on site along with a number of other builders, Ralph was highly knowledgeable and clearly explained what was required with practical solutions. DPS clearly scoped out the timeline and cost for each stage of the build and kept to this. They completed several agreed extras throughout the job. Communication with Ralph and the whole DPS team was first class throughout. I own a number of rental properties and can comfortably say DPS are the best builders I've dealt with, I cannot recommend them highly enough, they will be my first port of call for future work.

I recently used PrimeUK Contractors Limited for conversion works at our studios in Camden, and I couldn’t be happier with the results. The project timeline was set at six weeks, and the team delivered right on schedule. Pavlo and his team had a clear understanding of the scope and what needed to be achieved, going above and beyond to make the project a success. The quality and attention to detail in their work were outstanding, and my entire team was thrilled with the final result. Their pricing was competitive and fair, which was another bonus. When we have more work in the pipeline, Pavlo and PrimeUK will definitely be my first call. Highly recommend!

Extensions- 10 Apr 2021
Although I posted for a kitchen extension quote I decided that I would proceed with this at a later date. I did have a lot of other building work such as chimney removal that was undertaken by A2Z Property Improvement Limited. I am happy with the the work that was carried out. I'll certainly be reaching out to A2Z again for the extension once I'm ready to proceed. I would definitely recommend this company.

Latest review:
I received planning permission for a 3m extension, garage conversion and garden office with a toilet/shower and the architect recommended Timall. We of course carried out all our due diligence before selecting Timall as our builder. I received around 8 final quotes from various legal and reputable builders, and gratefully we chose Timall after checking their previous projects. Timall renovated my townhouse, stripped to brick, repartitioned to be more functional for my family, moved bathrooms, new kitchen etc. The council building control said we needed piling for the 3m extension, and Timall were fantastic to change their plans to carry out other internal work whilst a piling specialist was called in, who Timall also liaised with. The garden office, 3m extension and garage conversion all went well. Parminder the director was very hands-on during the project daily, with his builders on-site daily, honest in his advice, and very experienced in his knowledge of the building industry.

Roofing (Pitched)- 8 Jul 2026
Really happy with the work James and the team did. From the start, James was easy to speak to, answered all my questions, and gave a fair quote. They changed our flat porch roof into a pitched roof and did a great job with the tiles, leadwork, fascia and guttering. The roof looks really good, everything was left tidy afterwards, and the whole process was straightforward. I’d happily recommend Ridgewell Roofing and Building Ltd.
