Bricklaying- 19 Apr 2016
We have always found it a problem trying to match the correct tradesman to any work we have needed doing, so much so that many jobs have been left undone. You either end up with a personality clash, or just plain bad workmanship, well not this time. The entire process was a joy from start to finish, from the initial quoting process, to the completion and the standard of work was exemplary. Nothing seemed to be a problem for them and they were very pleasant to have around. We are busy drawing up a fresh list of jobs we need doing and would certainly thoroughly recommend them. If you have had any bad experiences in the past, give them a try, you will be very satisfied.

Restoration & Refurbishment- 21 Nov 2023
Slawek and Andrew did an amazing job on the front and side of our terraced house. The quote was fair (and they stuck to it) and the attention to detail was refreshing. We were kept informed throughout the works - communication was excellent. I whole-heartedly recommend SM Refurbishment.

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.

Plastering- 25 Feb 2020
Rob provided a very reasonable quote and started work on time as agreed. He scraped the artex, boarded sections, prepped and plastered both ceilings over two evenings to a very high standard. Both ceilings were ready to paint after a few days drying and were smooth with no trowel marks or hairline cracks at all. Rob also assisted with measuring up my kitchen for a new kitchen to be installed, he provided a better quote than Wren to fit the new kitchen, I will be proceeding with Rob to fit my new kitchen units based on the advice he has given me and the high standard of work he has carried out for me over the past couple of weeks. I would highly recommend Rob to anybody and I will be contacting him again for any future work I need assistance with whilst refurbishing my new property.

Conversions - General- 8 Oct 2022
Valentin, Dan and Chris did a great job turning an old wooden shed into a beautiful teenage den / home office. They stripped the shed down to the original wooden frame, replaced the roof and cladding, subdivided the internal space into two rooms and a small shower room. The job was reasonably priced though there was a little scope creep much of it due to additions to the original specification that resulted in an increase in price. With hindsight we should have made sure we kept track of additional work. They were friendly, tidy and considerate in the work and the dog loved having them around. They were professional and hardworking and we were pleased with the final result which was excellent value for money. We would recommend Valentin and his team and will have them back to do more work for us.

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.
