Jack has been amazing from the very start to finish with our extension project. He explained everything every step of the way, was clear about pricing, agreed to do extra work for us too like our garden patio and fences. Nothing was ever a problem and we couldn’t be happier with our kitchen extension - would recommend Jack to anyone!

RS Building successfully delivered two full back-to-brick refurbishments and a new-build development for us in Greenwich, including demolition and construction of four new dwellings. Their level of workmanship is exceptional, and their attention to detail is second to none. As experienced property developers, we’ve worked with many contractors—but RS Building stand out for their reliability, quality, and professionalism. We have since recommended them to several colleagues, all of whom have been equally impressed. Our only regret is not finding them sooner. We look forward to working with them again on future projects.

Extensions- 24 Jun 2017
We had a large piece of work done by Johan and his team. It was a 4m single storey rear extension with new kitchen installation, converting the old kitchen into a downstairs bathroom and utility room, plus other bits and bobs like new boiler, rear patio. We got quotes from a few builders, Home Renovations weren't the cheapest, they were actually towards the higher end. But we went and saw their previous work and spoke to some of their other clients. The work was done to a high quality and the clients seemed to be happy so we decided to go with them. Johan's team are very hard working, professional and polite. Pawel and his team of builders, bricklayers, plumbers, electricians, etc. would turn up before 8am and finish at 6pm working solidly throughout the day. There is Magda as the project manager who keeps you in the loop, and answers any of your questions (which we had many). There is Michaela on the finance side who keeps you up to date with the budget. Our budget went over by 5% with "variations" (extra work or materials) but it was always communicated why and the work wasn't done without our approval. Pawel would give his recommendations but the final word would always be ours. But these things can add up. Overall we were very happy with the build, it was done to a very high standard. They also finished it before time. They said it would take 12 weeks in fact they finished it in 10 weeks which was amazing as you would normally expect these things to go over.

Extensions- 16 Oct 2023
Mariusz & his team are amazing, from start to finish they have been fantastic & we cannot recommend them enough. We met with a couple of builders for quotes & felt like our project would be in good hands with Mariusz, we instantly liked him & had a good feeling. He was happy to talk through everything with us, answer our questions & nothing was a concern or a problem, this continued throughout our whole project. Communication was faultless throughout, which in our past experience is unheard of & Mariusz was on site multiple times a week. The team were polite, hard working, tidy & professional. Andrew & Pavel were the main guys on our build & they were amazing. They arrived the same time every morning & worked so hard 6 days a week. We cannot believe how quickly & professionally they carried out each stage of the build, which ensured all timelines were met. There was no cutting corners, the quality of work was excellent, with many of our neighbours coming over to comment on their craftmanship, especially the brick work. Our local council building inspector assigned to our project was satisfied & complimentary of the build throughout, no concerns were raised. Doing any size home renovation project & finding someone you can trust & rely on can be daunting. However, Mariusz & his guys really are who you hope to work with. If you are looking for a team then look no further, you will be in safe hands. It's been an amazing journey & a pleasure to work with Mariusz. Thank you

Loft Conversion- 29 Apr 2023
My house was totally renovated by this company. I was very satisfied with much of the work. I was informed that I would be given the buildings certificate and the electrical certificate for works completed once final payment was received. I was given the buildings certificate. I was not given the electrical certificate, although the house had been fully rewired as part of the work. I chased up for the certificate but my requests were ignored. I was aware an electrician had come to inspect the works, and the builder who had been on site indicated it appeared to go well. I have now just recently had the electricity in the house inspected by an electrician and have found there were issues that required rectifying.

What qualifications and experience do you have as an extension builder in Addlestone?

An extension builder in Addlestone should have a strong track record with similar projects and relevant building qualifications or trade memberships, such as the Federation of Master Builders (FMB) or TrustMark.

Will my home extension meet all building regulations and planning requirements?

What experience do you have with similar extensions in Addlestone?

Ask to see examples of their previous work, or view examples of their work on MyBuilder. Ideally projects similar to yours in scale and design. This helps you assess the Addlestone extension builder’s ability to deliver a result that meets your expectations.

Do you offer a guarantee for your work? Most Addlestone extension builders offer a guarantee or warranty on their work, often between 1 and 10 years depending on the project and materials used. This gives you assurance that any issues will be resolved after completion.
