Composite Front Doors
Our composite front doors combine a solid timber or foam-filled core with high performance outer layers for maximum strength, insulation and style.
They’re one of the most secure front door options available and come in a wide range of colours and finishes, including traditional and modern styles. If you want something that looks great, feels solid and keeps your home safe and warm, this is a great choice.
uPVC Doors
Our uPVC doors are a popular choice for both front and back entrances. They’re energy efficient, easy to clean and come with multi point locking systems as standard.
Available in a variety of styles, colours and glazing options, including traditional panels, timber effect finishes and modern designs. Ideal if you’re looking for a reliable and cost effective upgrade that still delivers on appearance and performance.
Patio Doors
Open up your living space with a set of beautifully made patio doors. Choose classic French doors for a timeless feel, or sleek sliding doors for wide openings and uninterrupted views of the garden. Available in uPVC and aluminium, all options come with high performance glazing, smooth operation and enhanced security.
Bifolding Doors
Bifold doors are perfect for large openings, extensions or anyone wanting that open plan feel. The panels fold neatly to one side, creating a wide, unobstructed transition from inside to out. Ideal for kitchen diners, garden rooms or rear renovations, they’re available in a range of finishes and can be configured to suit any space.
