JMB Windows is a very well established company, and after 15 years of trading we are known throughout London and the Home Counties for working with top quality products and offering exceptional service.

An enviable reputation

JMB Windows is different from most other double glazing companies. We have earned an enviable reputation for providing quality and a service that’s hard to beat.

We do not engage in high pressure sales tactics, we do not offer ‘false incentives’ or ‘fantastic giveaways’. Neither do we inflate our prices or offer discounts to encourage you to sign on the dotted line.

We might not be the cheapest around, but with JMB Windows you get what you pay for.

We will provide a competitive price that offers real value for money, quality products, skilled and experienced installation teams with a reliable after sales service.

There’s a reason nearly 80 per cent of our new business comes from existing customer referrals!
