“Sureseal were brilliant. Called them for a quote and Darren came out to measure. He told us he would call later with the quote. There was no hard sell (completely different attitude that safe style). Price was really reasonable and the guys who came out cleaned up after themselves every day. Really happy with the job and I recommend them to anyone who asks”
