Amazing job and a brilliant team of tradespersons. An excellent job of the herringbone tile flooring with underfloor electric heating for the whole of my downstairs. The wall panels also complemented the flooring and were installed perfectly. Well done to Bujar and his team!

Extensions- 30 Jul 2019
Nathan from HCJ Building Service was excellent in all respects. He built an extension to our garage, which involved block-work, timber framing, roofing, cladding and installation of a door. When he visited the site to provide an estimate, he was enthusiastic and knowledgeable. His quote was competitive and he promptly answered a few questions we had about some of the technical details. When working on the project, he always arrived when he said he would and left the site tidy when he finished. My wife and I were impressed with how hard he worked, barely stopping to drink a coffee. When we interrupted him to find out how things were going he was happy to give us an update. He was always friendly and polite. He completed the project on time and left the site as he found it, removing all his waste. The work was done to a very high standard. We are really pleased with the result. This extension has freed up space in the garage for my woodworking hobby. We will definitely be coming back to Nathan to quote for future building projects. Now that I have my woodworking man cave my wife has started thinking about the kitchen...

Roofing (Flat)- 24 May 2026
Martin came and saw the job promptly. His quote was a little more than another I had had but he made a couple of suggestions and generally demonstrated he knew what he was talking about so I chose him. The job was done quickly and well in a day. It hasn't rained heavily yet but the roof seems perfect. Martin did say that if there were any problems to call him. I am sure everything will be fine but it's nice to have that kind of customer service. Highly recommended!

Extensions- 26 Jun 2018
Andy and his team came to build my single story extension. Could not recommend him highly enough for his high quality work and finished product. Finished all the work to the time scale he told me and turned up everyday from start to finish. Always communicated with me to understand what was going on with each stage and went above and beyond to help me. Very clean and tidy. I still have lots of work to do with a garage conversion for one, and will not hesitate to use Andy again. Brilliant. 10/10

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.

Garden Maintenance- 27 Aug 2015
Thames Garden Services gave a very competitive quote and delivered a lovely lawn and managed to fix a few other issues in my garden (poorly laid patio, fencing at side of house) with great results. Jim made sure we understood everything we needed to know, and went beyond the expected level of work (such as breaking up concrete to secure the fencing) at no extra cost. Jim even entertained my kids while fixing the pointing on my patio! Would definitely recommend Thames Garden Services for any landscape garden work, patios or fencing, and will be looking to use again in the future. Many thanks to Jim for all the hard work, rain or shine.

Windows & Doors (uPVC & Metal)- 28 Jan 2026
Very unhappy with how things went with Angle Construction overall. Poor comms during the transaction was the first red flag - no communication for 2 days the moment money was sent, however afterwards received an apologetic call - parts ordered and arrived in due course. Andrei turned up, and got to work on removing the old gate, but then started shaving down the post without saying anything -we were told after that the posts were not level. Eventually he said the door would need to be cut, which we agreed to. The door and posts were both cut to fit, but massive gap left at the bottom, and only half of the door fittings and no handles were installed! In addition, where the door was cut and the wood shaved made, a lot of mess was left all over the garden furniture and patio floor. Shocked at the lack of care and professionalism. He was clearly agitated and in a rush to leave. We have a working back door, but it looks like a real botched job. Not happy, and I would not recommend.
