Restoration & Refurbishment- 2 Apr 2026
My property needed major work in a number of areas; 1/ internal plumbing, within the roof and below had caused leaks internally, 2/ The old rendering had significant cracks and had allowed water ingress causing damp, 3/ The old roof lacked a membrane and had gaps which was allowing water through and 4/ The old electric fuse board needed replacement and electrics to be checked. Stefan and his team work tirelessly on all aspects of the work and he ensures that everything is done to a high standard. Stefan is a professional and trustworthy builder who will advise on what is right and he always works in partnership with his customers. I recommend him without any reservation.

Conversions - General- 29 Jul 2015
Found John to be extremely helpful in giving ideas for problems which came up. Would Highly recommend them, they were very happy to come back and sort out a few snags even after full payment was give. When a wall was been taken down a lot of dust and mess was created as you would expect and we came home to the guys mopping the floor to try and tidy everything up! Other positives were how flexible they were with working times such as early/late on weekends and evenings in the week. Can't recommend them enough, great price and it felt like they treated the job as if it was in their home. Will use on our next project for sure.

Roofing (Pitched)- 18 Jun 2025
I was in need of a quick roof inspection to make sure that the works carried out by another roofer were to a good standard. Shilhaad was very prompt to get back to me and had outstanding communication from quotation through to delivery. He was fair and impartial, turning around a report on the same day. He was very friendly, approachable and knowledgeable. Thanks to Shilhaad, I can go back to our initial roofers with some evidence on work that needs to be redone. My only regret was not using Shilhaad and his team to carry out the roof works in the first instance. Thanks again!

Conversions - General- 30 Sep 2020
Agim gave us a very reasonable quote for the removal of a chimney breast in our downstairs utility room. Although it's normally a very messy job, they took care to keep the amount of dust and mess to a minimum. Everything was finished to a very high standard, they didn't cut any corners or rush anything. I would definitely recommend A&B - they are an excellent, reliable company.

Loft Conversion- 5 May 2017
Artjom and his team have done a wonerful job on our loft conversion and house renovation. We are very pleased at the transformation. Although not the cheapest quote we obtained, they were highly professional, kept the noise down and cleaned up after themselves. We also added several other jobs to our initial quote and they undertook these as requested. It is important to keep a record of everything you ask to be done. They worked very fast and were able to complete everything within 2 months - it helped that our house was empty at the time, so they didn't have to deal with us living there at the same time as the works were being carried out. Overall, I would highly recommend Adam Renovations for any building works you need done to your property.
