What Clients Say
Don't take our word for it, check out what our clients think of us:
I went with Centiam to replace our fasicias, soffits and gutters as well as putting a new flat roof on the extension at the back of the house. From the initial interaction with Paul to discuss the work required and quote for the job through to the work itself carried out by Nathan, Martin and another Paul I couldn’t have been happier with the end result. It’s made a big difference to the house and the guys couldn’t have been easier to deal with and they did a brilliant job. It’s the first time I’ve ever reviewed anything online but I decided to make an exception in this case.

Carlo from Centiam responded quickly to our post to replace fascias, soffits and gutters. He came out same day and priced job. Agreed installation date. The guys came on arranged date and carried out the work, cleaning up as they went. Did a really good job, and have no hesitation in recommending them.

Once job was started the tradesmen were very good and tidied up after themselves at every stage of the job. Communicated well throughout the job and were no hinderance whatsoever. Would absolutely recommend the company to anyone looking for a similar job without hesitation.
