Kitchen Fitting- 25 Jun 2026
It was a pleasure to deal with Florin. He came quickly to give a competitive quote. He then did the work in a professional and friendly manner. He is assiduous in his preparation, checking some tricky measurements at least a couple of times before starting. He kept me informed of progress and checked in to ensure I was happy with the job. He turns up when he says he will and works hard to make sure things go to timeframe.

Groundwork & Foundations- 13 Jun 2024
Artan is punctual and professional. Did a great job on gravelling my front garden and tidying up afterwards. This involved laying weed membrane, gravel grids and then gravelling. He also built up the borders using paving slabs to avoid the gravel runoff. The finished job was very good. He charged a good price for two days work. I wouldn't hesitate to hire Artan again as he's reliable, professional and very personable too. Which makes him very easy to work with.

Extensions- 26 Aug 2021
SSS BROTHER, They worked incredibly hard to transform our house in a timely and efficient manner, all whilst being responsive to our concerns and preferences. The SSS BROTHER did a great job extending our kitchen and backroom to create a beautiful space that we love hosting family and friends in. The job was completed to a high standard and with good communication. Throughout the work, the workers were calm and knowledgeable and - importantly for us - helpful and offered their opinion of how the extension should be built.

Restoration & Refurbishment- 31 Mar 2025
J&G did a fantastic job of renovating my kitchen, including removing the old units, altering a chimney breast according to Planning Permission guidelines, plastering, painting, moving the radiator, laying a new floor, running new electrics and fitting new units and appliances from Wren. Jurgen is an excellent communicator, always taking the time to explain what was going on and answering questions. I particularly appreciated his honesty about the structural challenges of altering an Edwardian chimney breast, proposing alternative solutions which were cheaper and less disruptive. The quality of the finish was really good - from the electrician and plumber to plasterers and painters, all his team took great pride in their workmanship, and were all polite and friendly. Although the overall length of the project got extended, Jurgen made sure all the snagging was thoroughly completed. Overall, highly recommended and a pleasure to deal with. I'd definitely hire Jurgen again.

Khin and Senh did an amazing job redoing all the skirting in our home. Their quote was competitive and their workmanship outstanding. They helped us source the materials to our specification for a great price, handling all the delivery details and were happy to pick up any bits and bobs to get the job done. Each day they arrived on time and often worked late to accommodate the fact we had carpets coming in the following week. After each day tools and materials were squared away and they would send updates on progress. The final product was top quality and has nicely finished off our home as part of a large book of renovations. Finally any snags that I did notice they were happy to come back and address, I couldn’t have wished for any more from these guys. All the best !

Insulation- 28 Feb 2023
A Great British company who I will call first for all future work. I have multiple properties and seen many traders. Workmen never give compliments to others but two of my regulars were there and both told me his work/team were very good. DBMP treat the work like it is their own property. Good quality work, neat, thoughtful of other workmen/tenants, took all the rubbish away. No mean feat as he replaced skirting & floorboards, installed rock wool and rubber mats, re-fitted carpets, painted woodwork and moved furniture in & out; all while I had tenants in the house. This site is a gamble but I highly recommend this team.
