I deal with their London office and Dan and Armundo (SP?) and their team are top notch. Very professional and very "by the book". Clearly their business model is set up for large jobs but they are quick to fit in the smaller jobs if they can. For flat roofs or terrace waterproofing, these guys are my first call.

i have found them great to work with , slowed up a flat roof leak in the freezing cold and came back to do a permanent repair in warmer weather

This company has completely no sense of customer service. I called them in to check out a roof leak. The first visit was reasonably responsive. But the leak continued; there was probably more than one source of leak. They were not interested in further investigations. No response to phone/emails. How desperate are you?

Great company excellent work big on safety.

totally useless company, never replies back to phone calls or emails.I do not recommend to anyone even for a roof for a dog house, don't waste your time
