Extensions- 5 Oct 2022
These guys came and did an awesome job. They finished a job that another builder left me in a real mess with. So many other builders weren't interested at all. I was told nobody would finish another's job. A bodge job at that. But Reno renovations did just that. And, did an awesome job! Look forward to them doing the rest of my projects.

Conversions - General- 17 Aug 2026
Excellent Builder – Garage Conversion, Shed & Loft Boarding. We’re really pleased with the work carried out on our garage conversion, garden shed and loft boarding. From start to finish, the whole team were friendly, professional and extremely cooperative. They were very accommodating when we made changes or came up with new ideas during the project, and they were always happy to discuss options and find a solution. Nothing felt like too much trouble, which made the whole process much easier and less stressful. The quality of the work was excellent, and they also helped us with obtaining the Building Regulations certificate, which was a huge help. We would definitely recommend them to anyone looking for reliable, professional and approachable builders. We’re very happy with the finished work and would happily use them again.

When I was looking for quotes, Lukasz was the only builder who provided a fully detailed breakdown. From the start, he was professional and punctual, arriving exactly on time for our first meeting. He offered great recommendations on the best ways to approach the refurbishment and was flexible enough to let me source my own materials. Most importantly, he provides a warranty which he has already honored to fix a minor fault from another professional. It has been a pleasure trusting Lukasz and his team with my full house renovation.

Extensions- 27 Jul 2023
I would be happy to use RDS buiding services again. They turned up every day worked efficiently and kept the mess created by the construction out of the way of the neighbours. The budget we agreed was followed and the stage payments schedule worked throighout the build. I am very happy with the quality of the work and more importantly the attitude of the builders who worked with us when inevitable snags came along. We invited RDS to do some additional work (landscaping in the garden) which did not detract from the main job. Thanks RDS for a job well done.

Extension Builder in Southam
I am a builder with 20+ years of experience, which has allowed me to specialise in pretty much every field of the sector; from tiling to fitting kitchens and bathrooms to painting etc... I am very meticulous in every job I do and always try my very best to please costumers. What I believe makes me stand out from other tradespeople is that I acquired most of my experience in Italy which is where I lived before moving here 4 years ago. This has helped me achieve different techniques and skills.

Bathroom Fitting- 7 Oct 2022
Initially did a good job but then rushed the silcon round the bath/ shower that then leaked. Kept telling us he would fix it but after more than a month I gave up and fixed it myself. Shame really, another tradesman that is fine until things go wrong!

Diako and Ali Raza did several things in our house- changed radiators, put in engineered oak floors and also made us an under stairs storage. They finished in 3 weeks and the quality of work was to a good level. They can do good carpentry, plumbing, painting and electrical work. I highly recommend them.
