Carpentry- 19 Apr 2012
It was an absolute pleasure having Danny round to fit our new Front Door. He arrived promptly, worked extremely hard and completely the job to a very high standard. He always works with a smile on his face and is an extremely amiable person. You will not be disappointed if you hire him for the job and I'll certainly be using him again in the future.

I recently completed the building of an orangery extension (with skylight) to my semi-detached townhouse in NW London. The extension was to be used as a new kitchen while the existing kitchen converted to a living room. I awarded the contract of building the extension to Anthony and I was pleasantly impressed with the quality of work delivered. Anthony Project Managed the entire process from beginning to end and ensured that all my expectations were surpassed. His hands-on attitude to every detail of the work was quite reassuring. I am glad to say that Anthony and his team are very good professionals and they delivered the project on time and within budget, even going over and beyond the original scope of works in order to ensure that all my latter requests were addressed appropriately.

We were absolutely delighted with Lino and his services. He was incredibly patient , as our flat purchase was delayed. We required a total gutting off our flat, with new kitchen and bathroom, new flooring, painting, and all the rest. He had great communication throughout. He showed up on time with his team each day , and was so professional throughout. We went to Lino for advice throughout the process. He never said any of our plans were not possible- he always either said yes, or provided another option. This was such a great help. I would recommend Lino to anyone. We are absolutely delighted with our flat.

Bathroom Fitting- 25 Mar 2024
He was good when doing the job, and workmanship was very good, I cannot complain about that. I think what let down the entirety is aftercare & integrity of the builder. The fact we had given him multiple jobs in our house not just this one, and the first big issue we had within the first 2/3 months where our electrics stopped working in the bathroom for him to refuse to come unless I paid him £80? People usually give warranty with work and he claimed he doesn’t give more then a month which I find concerning especially with plumbing work, imagine a small leak getting worse over time before finding out. Luckily I had building insurance so when an electrician came out he said the builder had not tightened the pull switch which came loose, and I’d have had to pay to just tighten a switch. Now he’s blocked me on what’s app & for me that’s concerning and very unprofessional

Extensions- 10 Jun 2020
We had a one bedroom lower ground floor garden flat and did a side return and extension into the garden. The flat is in West Kensington area. We also did a full internal refurbishment and moved just about every wall, moved boiler, new Porcellanosa bathroom, new kitchen, new flooring throughout, a large bi-fold door in the living room to the garden. Chris and RAS Construction have been the best possible builders for this project. They were simply amazing. What we loved most about them: - speedy and no-nonsense communication (very important for us) - friendly and approachable - super professional and friendly team - very quick and helpful when a problem arose due to some architect's error - good aftercare - stayed in quoted budget - offered improvements and reasonable quotes - very easy to work with - only asked for partial payment every few weeks after job had moved along reflecting the amount charged This review was written about 8 months after the project was completed and we are still very happy with the quality. I would not hesitate to recommend Chris and his team at anytime. You hear so much about bad builders, we have been very lucky that we have found him. We are now house hunting for a bigger place and will re-engage with them for the next project.
