Andy is a very personable individual and clearly helps customers make the best choice for their situation, rather than the usual mercenary approach. He was punctual and thorough. Should be on your shortlist for a quote.

Used Sustainable Plastics twice now. Did a small job a flat roof above a bay window first time, and done the back windows including a French door since. Really knowledgeable lads that are professional and accountable. Highly recommended.
