Extensions- 12 Jun 2020
Matt, Rob and the team have been absolutely brilliant in managing and building our extension. There were a lot of challenges around the build to manage; we had awful December weather with rain every day but the team worked weekends to keep to schedule, and there were issues with the structural engineers plans and the kitchen designers - not to mention the arrival of lockdown, but they dealt with every issue brilliantly and positively. The team are a pleasure to have around the house, and Rob found a solution every time we had a challenge. The work is of a very high standard - we are amazed how well they have matched the exterior and they offered good advice for us on how to make the most of interior space as well as being very collaborative in finding ways to be as efficient with the budget as possible. This was not a huge external build but it was very complex inside as we were reconfiguring rooms & knocking through rooms, and the team managed a complicated process expertly. I highly recommend the Groundforce team to anyone looking at residential building work. They have been first class.

Extensions- 8 Mar 2025
Charles and his team did a brilliant job on my double garage extension. Start to finish Charles and his team were really polite and clean workers. Charles was always in contact with me and giving me updates daily and always kept me in the loop at every stage. Project was completed to a really high standard, a very reasonable price and in good time! It wasn’t the easiest build due to a water leak from Thames water nearby causing a mud pool but it was still completed in a great time frame! I can highly recommend them for any works!

Painting & Decorating- 29 Apr 2026
After being let down by a previous tradesman, finding Eddie was a game-changer. He recently completed decorating, painting, and detailed woodwork at our property, and the results are fantastic. From the start, Eddie was professional and straightforward. He provided a fair quote and stayed true to it. Why we highly recommend him: Punctuality: He arrives exactly when he says he will. Incredible Work Ethic: He is extremely hardworking and dedicated. He even worked late and through weekends to get the job finished. Cleanliness: He is incredibly respectful of the home, leaving everything tidy at the end of every night. Knowledgeable: He clearly knows his trade inside and out. He even took the time to teach me a few things along the way! We are so impressed with his work that we are already planning to hire him for our upcoming bathroom and kitchen renovations. If you are looking for a builder who is reliable, skilled, and honest, Eddie should be the first person you call.

Andy built a large single story extension at the back of our house in 2013. It is a contemporary design with two sets of large bi-fold doors, two roof lights with a modern rubber roof and zinc fascia. The work included laying a new patio and tiling inside also. A number of internal walls had to be removed so quite a complex job. This is the fourth project that Andy has completed on our house - prior works were bedroom and office extensions, wall removal in kitchen and exterior retaining wall. I have always been delighted with Andy's work hence using him for all of our projects on this house. He is very skilled, sets very high standards for both himself and any trades he brings in, has an amazing work ethic and is a builder that you can trust. I am more than happy to be a reference for Andy.

Extensions- 11 May 2026
These guys are the real deal. So very impressed with the work that that have done. You can tell a lot about a building company with what condition they leave the building site and they left it spotless and very clean. Which lends itself to the high level of craftmanship they have put into converting my brick shed into a gym. Nothing is a problem for them and they turn up on time when they say they are and crack on with it. Mark offers recommendations for the work and due to this what I initially requested is even better than I expected. It has been a real pleasure having them on site and would offer them future work for sure.
