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.

Handyman- 26 Jun 2026
Hired Madelin recently for home renovations which included removing wood chipped wallpaper, plastering/skimming from living room + hallways. Was so impressed with Madelin's tireless hardwork, attention to detail, and craftsmanship that I also added replacing laminate flooring too. Quotes were transparent with breakdown on services and materials. Madelin also accommodated extra work too for a fair price and very small things free of charge which I appreciated. Overall, I was extremely pleased with Madelin's tidiness, punctuality, transparency/ honest communication and final finish of my home renovations. Would highly recommend and have favourited for future home renos.

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.
