Restoration & Refurbishment- 13 Aug 2019
David and his team were excellent. They are always on time and very professional. They always cleared up at the end of the day thereby leaving very little dust or dirt around the house. No query or issue was ever insurmountable; the answer was always "no problem", which was a joy to hear when having such a large project to do. Each different team i.e. electrician, plumber, arrived exactly on schedule so there were never any delays. The end result was amazing. I highly recommend David and his team.

Carpentry- 19 Sep 2015
Not only was Ian's quote to do the loft conversion very reasonable, he was very reliable, tidy & very helpful when we had a difficult situation. The work was done in a quick time, when he said he was going to be on site he was, at no time did he let me down. The standard of work was excellent, I would recommend Ian & wouldn't hesitate to use him in the future.

Ahmad and the Beam Developers team did an amazing job on my rear extension. We were very particular with our requests and are generally picky people but they were very patient and accommodating to our every request. We were shown the drawings, made adjustments and managed to tailor the project exactly to what we wanted. The finished results were amazing. No big project for us soon but should we plan to do the loft will definitely use Ahmad and his team again.

Jason and his team built to exact specifications an outhouse with in ground swim spa and decking. I am actually in love with the build and how it has positively impacted our lives. Jason and his team were great communicators and everything was built exactly how I envisaged. Building Control and council signed off everything with great ease and we now have pretty much a holiday home in our back yard. We've got a purpose built studio flat with private access, a spa style shower room and a large gym/games room. The team came up with innovative ideas to store the tank and the electrical cabling and it is a beautiful space to have. Would highly recommend them and would welcome working with them again in the future.

Extensions- 30 Nov 2020
A really excellent set up of builders. Peter was great in evaluating the work and what we needed done. Sue was clear in her communication on costs, and then execution of the works by Taras and his team was superb. The extension was built in fantastic time-frame, and the end result is great. The work-ethic of the builders is what really makes them so good. They are on-time every day, and relentless with working hard each day.

Carpentry- 8 Apr 2026
I’m really happy with the work carried out. He came in to fix my steps after a previous builder had damaged them and left them unstable, and the difference is night and day. Everything now feels solid, secure and properly finished. He also fixed the skirting boards and installed my desk, all to a very high standard. What I really appreciated was how professional he was throughout and the advice he gave along the way, which showed real experience and care for the job. Overall, a really high-quality finish and a great attitude. I wouldn’t hesitate to recommend him.

Hello to all visitors to my profile. My name is Przemek, I deal with interior renovation, bathroom finishing and kitchen installation. I owe this to my acquired experience. I have been working in UK for 7 years, of which for 1.5 years I was a bathroom and kitchen fitter at the "WICKES" store. I am a precise and aesthetic person. I love order at the workplace and I like seeing a smile on a customer's face.

Groundwork & Foundations- 7 Nov 2024
From start to finish, Bogdan and his team were exceptional. After dealing with a previous builder who caused numerous delays, I found SBG Services. Bogdan came by the same day to assess the job and impressed me with his extensive knowledge. Given my tight schedule, he got to work immediately. I’ve never seen a builder work as hard as his team; they labored tirelessly from morning to night to ensure the project was completed promptly without compromising quality. Every trade I've had since has commented on their attention to detail. In just three weeks, they completed two extensions and transformed my garden. I will definitely be calling Bogdan back to handle my front garden early next spring.

Restoration & Refurbishment- 19 Apr 2025
Positively, certain aspects of the finishing, particularly tiling, were carried out to a good standard. However, the overall experience was mixed due to significant issues. There were notable challenges during the project involving basic logistics and site management, leading to considerable inconvenience that seemed avoidable. Furthermore, the quality of workmanship was inconsistent; while some parts were good, other areas involving fittings and fixtures showed a lack of attention to detail in the finish, requiring later adjustments. Communication during the process could also be difficult, particularly regarding problem-solving and planning for materials. While we appreciated the parts done well, the project was let down by these inconsistencies and process issues, leading to some ongoing snagging and disappointment.
