Roofing (Pitched)- 8 Jan 2026
Suad was straightforward and professional to deal with. He inspected the issue, explained the likely cause of the leak, and carried out the agreed repair without suggesting unnecessary additional work. Communication was clear, costs were as discussed, and access was arranged safely. The scaffold was left in place to allow the repair to be checked after rainfall. Overall, a satisfactory experience.

Conversions - General- 9 Dec 2016
Andrei and his team did an amazing job with my house. They refurbished it to the minutest detail, and made sure everything was executed as requested. They worked consistently and efficiently for 4 1/2 months, in order to deliver. They started around the second week of April, and I was able to move in on the 3rd of August. They did wiring, pipping and flooring. They knocked off a wall to create an open plan lounge/dining area. They removed chimneys to make more space, and re-plastered and re-painted the whole house. I am very happy with my new home and I am already thinking of hiring Andrei and his team to convert the loft. Working with Andrei was a pleasure. During the last month, I was in touch with him everyday and would visit the property 2 or 3 times a week, to check on updates and see how things were being done. It is very difficult to find trustworthy builders, but Tudor Constructions are professional and always happy to listen to their clients. I would definitely recommend Tudor Constructions.

Demolition- 24 Nov 2021
We employed A.V Structures for the building of an external wall around our property, the removal of a garage and the installation of railings and gates. Throughout the 4 week programme we could not have been happier with their work. Arrival was prompt, their pace of work displayed energy and purpose. They were mindful of us and our neighbours and made sure the area was left clean and tidy at the end of each days work.in addition the workmen were courteous and kept us fully informed. Alex, the owner of the company, kept in close contact with us to assure himself of our satisfaction. He came on site at intervals to check that all was going according to plan. We therefore felt completely confident that quality and outcomes were important to him. Employing A.V Structures was a decision we were pleased to have made. We would use them again without hesitation and recommend them highly to anyone considering similar work.

Bathroom Fitting- 27 Mar 2024
Driton was able to give me some great advice, fix the problem on the spot and stop me paying out for a new cistern and toilet. So he saved me a lot of money and the inconvenience of having my bathroom turned upside down with building work, re-tiling etc. I'm very grateful.

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.

Alton and his team at Bluelime have been incredibly helpful and enthusiastic throughout our design and planning process. From the start, Alton took his time to understand our needs and propose several cost-effective ways to improve my home and create more space for my growing family. The design process was completed efficiently and submitted for planning permission, which was granted without a problem. Since then, his team have continued to be helpful and communicative despite my need to delay to the building works due to unfortunate complications with my freeholder.

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!
