We all know how you generally pay for what you get. We also stress to all of our customers that we do not employ sales people, and our surveys and quotations are “no obligation free of charge”.

When you recieve your quotation it wont be an over inflated unrealistic price, to be lowered at a later stage, often the tactics used by so many window companies out there! We will give you, “Our price! That is our best price! Our only price!” This has worked for us for Three decades and we believe, its the only way to carry out business.

We take pride in offering to you, a workforce that are qualified craftsmen, giving a high standard of workmanship in a what can sometimes be a “Cowboy Competetive” market. A dedicated aftersales department that will continue to support you and your product throughout its lifespan, and to top it off, all this comes from a local family business, that takes great pride in each and every installation.

The quality and strength of the uPVC can differ greatly between companies. Carnforth windows ensure we only install optimum colour, brightness and quality for our replacement windows. You can see this for your self by watching this short film clip
