Do you want a door which looks like a wooden door, but requires extremely low maintenance? Then choose a composite door. We offer an extensive range of composite doors at very competitive prices. When you choose a door from Seal uPVC, you can be sure that you will be happy with both our product and price.

We are helping more and more of our customers save money each year by reducing heat loss through having more thermal efficient windows fitted. All our uPVC products are custom made in our workshop and are independently tested and kite marked. Not only do we work closely with homeowners, we also work closely with commercial building owners and housing associations on large projects on a regular basis. Offering uPVC windows in a range of styles, sizes and finishes, our highly experienced professionals can offer advice on which type of windows will best suit you.
