Stylish Doors for Homes in Lancashire & the North West

Great Harwood Window’s range of entrance door styles are more than ready to keep up with the demands of the modern homeowner, whether required for use towards the front or back of the home. Comprised from some of the industry’s most respected door systems including Rockdoor, Solidor, Veka, Liniar and others, all deliver excellent style, operation, and protection for nearly every project requirement.

What is a composite door?

A composite door combines all the best elements of multiple materials, fused together under high-pressure conditions to create a door that is incredibly strong, secure and energy-efficient.

Glass Reinforced Plastic (GRP) skin keeps them resistant to scratches and marks. Meanwhile, their foam or timber insulating cores significantly slow the rate of thermal transfusion, helping the door to prevent heat loss. The result is a door that not only looks beautiful, but also saves your money on your energy bills in the long term.

Quality doors in a range of styles

Whether it's bifold, stable, french or patio doors, all our products are manufactured with quality at their core. Whatever the style of your Lancashire home, we're confident that we can install the perfect door for you.

Homes in the more rural parts of Lancashire, for example, may benefit from the ornate and traditional style of the stable door. Meanwhile, properties in more metropolitan areas like Preston and Blackburn may prefer the sleek, modern aesthetics of our stuning sliding patio doors.
