Lovely father son business, professional, friendly guys. I asked them to build a plasterboard wall in order to create an extra bedroom in my house, the wall was finished well, within two days and they charged me a very reasonable rate, as a young women in business I find that tradesmen often try to overcharge me but these gentleman did not. They also took a look at leak that had occured which another professional plumber failed to solve and tried to charge me over £200 just to take a look! I have and will book them on a number of other jobs.

Restoration & Refurbishment- 15 Feb 2016
Pawel and his team modernised our two bedroom house from top to bottom. They installed central heating in every room, they removed our old warm air heating, made an open plan for the kitchen and living room area, installed new bathroom and kitchen units and did the tiling too, they updated our electrics and sockets and also plastered and painted the walls and fitted our wooden flooring for downstairs. The job was completed within 12 weeks. We were very happy with the modernisation, our home looks completely different and has a new modern fresh feel. We will definately be using Pawel and his team for future jobs. Thanks again Khalima

Extensions- 4 Jul 2026
We posted our building project on MyBuilder for the construction of a new outbuilding. We received a number of responses and quotes and selected EDSS Ltd. My elderly mother had used EDSS Ltd previously to do a number of renovations to her house and we found EDSS Ltd’s quote competitive and fully broken down. The work completed to date has been high quality with a high level of attention to detail. Stefan and his team managed the project from start to finish. This has included liaising with building control and other parties. We did not have to worry about any detail and Stefan always goes the extra mile to reduce any inconvenience. Stefan and his team were reliable, hardworking, approachable and always willing to discuss any questions we had during the build. The work was completed to a very high standard and we were kept informed throughout the project. We have no reservations in recommending EDSS Ltd and are happy for customers to see the work.
