Double glazing prices in Staines-upon-Thames & Egham

Staines-upon-Thames and Egham sit at the heart of the Surrey-Middlesex border, with a dense mix of 1930s semis, post-war estates and newer detached homes across Ashford, Stanwell, Laleham and Thorpe. The national double glazing companies are extremely active in this area — and the homeowners here are being quoted some of the most inflated prices we see.

The reason is simple: their salespeople work on commission. The less discount they give you, the more money they personally earn. That means the first price they quote you is not the real price — it is the price that earns them the most commission. The real price, the one they will accept if you know how to ask, is almost always significantly lower. Use the free Bottom Line Price Checker above and see for yourself.
