We began life as a small family firm, eventually growing to be the largest supplier and installer of windows, doors, and conservatories in the North East. However our company has never lost its family feel, which is why when you visit our close knit team you will find that we are warm and friendly, and that we always put the customer first.

At Warmseal we are proud to be able to provide you with the highest standard of product knowledge, advice and service, thanks to the investments we make in our dedicated team of experts.

We keep ahead of the game in product development because we work so closely with our suppliers. Just like many other firms, we have all the necessary British Standard accreditations. However, what sets us apart is that we strive to do better than these standards with every single product we supply. At Warmseal we go above and beyond because we care about the safety of our customers.
