Extensions- 11 May 2018
After a rogue builder left me with 18 (eighteen) structural issues. Lez and his crew came in transformed my failed extension into a masterpiece. All aspects of the job was done to the highest quality and utmost care and attention to detail was shown to building control needs. They cleaned up after every day and made sure the house was habitable, as I had to live there. Every aspect of the build, from the carpentry, plastering and tiling was first class and their recommend electrician and plumbers were from the same stock. Total professionals. My only regret is that I did not use this builder the first time. The prices were reasonable and even building control had good word to say about their work. Thanks Lez

Blueline completed the work to the exact high standard i was hoping for, while remaining on budget and estimated timescales - the three things that were most important to us! They were punctual, practical, knowledgeable and willing to give advice when either needed or when something could potentially be improved. They were always available to talk through what was happening at every stage of our job, with any complications arising, and importantly solutions to any problems. They knew their stuff and got the job done without any hassle either. They even came back after the job was finished to shift some pipework which i had an extra requirement for. The best feedback i could give is that we will go straight to them for any work we require in the future, and have already recommended them to friends.

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.

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.

Chris recently stripped and rebuilt two bathrooms in my flat, and I couldn’t be happier with the result. From the start, he took the time to understand my preferences and worked with my requests while providing expert advice on what was (and wasn’t) necessary from both a safety and future-proofing perspective. His extensive experience and knowledge gave me complete confidence to trust him with the entire project. What really stood out was how approachable he was throughout the process. Chris made it easy to ask questions and was open to last-minute tweaks when needed. He handled everything with real professionalism, from tidying up daily to managing disposal of all rubbish, and he kept my flat in excellent condition with proper floor and surface protection. Renovations are never entirely disruption-free, but Chris ensured everything ran smoothly and with minimal inconvenience. On top of that, his pricing was very competitive, especially compared to other tradesmen who seemed to overinflate or play the system. Overall, I can’t recommend Chris highly enough for his skill, honesty, and professionalism.

I recently hired Daniel to remove the fence in my front drive, and I couldn't be happier with the service. Not only was he incredibly friendly, but he also didn't charge an arm and a leg for the job. What really impressed me was how quick he was in completing the task. I would wholeheartedly recommend daniel to anyone looking for similar services. A great experience all around!
