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.

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.

Carpentry- 5 Jan 2025
Aaron initially impressed me with his commitment and fair pricing, delivering and installing staircases well. However, when he offered to tile a bathroom, things went downhill. Instead of handling it himself or assigning someone he trusted, he brought in a tiler he’d never worked with before. The results were disastrous—uneven tiles, poor grout work, and an overall lack of quality. Aaron offered to fix some issues but didn’t supervise the work, leaving it to me. His repairs only made things worse. After the job was finished, he ignored my detailed list of tiling mistakes and stopped responding altogether. I had to hire another tiler to fix some issues, but many problems remain because further repairs were too costly. While Aaron is an eloquent speaker and seemed committed initially, his actions didn’t match his words. I cannot recommend him and caution others not to be swayed by small talk or promises without clear oversight and proven reliability.
