Supreme is quite unique in the double glazing industry, we supply and install the best quality product and some of our installers have been fitting for Supreme for 15+ years, with an unblemished trading history since 1986 when it was first formed. Buying double glazing is a big investment. There are still a lot of hard sell companies in the industry, no price will be given on the first visit, so you do not have the pressure to sign on the night, you make your decision in your own time. What we do is. Give you the choice, on our first visit we would go though the details of the product you require, take measurements, this very often only takes about 20 to 30 minutes, then we will prepare a detailed quotation at our office, which we can e-mail, post or hand deliver to you. Or you can. Call in to our showroom or e-mail photos with the sizes, style/s and colour etc of the product, and we will quote on the information you havegiven.
