Testimonials

I found Clapham construction service on Youtube, when I was browsing, trying to educate myself on the process of a loft conversion. I was seduced by some lovely videos to be honest but invited them to quote for the works. To be honest without sounding so enthralled like some other reviews I’ve read… they did and acted exactly as they represented on the videos and website. I couldn’t complain about anything because they did exactly what they said on the tin. Having spoke to the owner a few times it seems they limit the number of jobs they do per year to ensure they the management can personally manage each job, that’s a good business model.

Clapham Construction Service completed our loft conversion. We are extremely pleased with the results. The work is of extremely high standards. It was important to us to have people we can trust. We are so happy – Thank you Dangis and Alfred. A word of caution for other builders - Originally, we took on another contractor who was £2000 cheaper, however it turns out that all they do is sell the project and sub contract the work to a 3rd party. When we received the contract to sign the first payment goes to the company and the remainder goes to the builders. The contract was actually between us and the builders… not the company. When I asked the company what this was about and what happens if the builders go bust… I couldn’t get a straight answer. Clapham Construction Service were straight and honest start to finish

I used this company for a complete house refurb and loft conversion in Battersea and was not disappointed by my decision. The quality of work was extremely high, with the project manager/ owner proved to be honest, resourceful, straight-talking and personable to deal with. Even when I had overpaid by £1000 they alerted me and paid it straight back. I particularly liked the teams working on my property: they were hard working, polite and had very high standards. I would strongly recommend this company for any project large or small.
