External Timber French Doors

We manufacture and install traditional timber French doors to suit the period character of your home.

Also referred to as patio doors, balcony doors, or French windows, wooden French doors are a double set of doors located at the rear of the property.

As specialists, we offer a wide range of styles of French doors to suit VictorianEdwardian; and Georgian period properties.

Made to Measure Traditional Back Doors

Established in 1994, we have 30 years experience manufacturing and installing timber doors to suit period properties.

Operating from our workshops in Berkshire, all our new French doors are made to measure to your requirements. We can either match the style of your existing external doors or provide a bespoke design to your precise requirements. Where necessary, we can conform to conservation area and listed property requirements.

We use a sustainable timber called Accoya, which is both durable and stable, requiring minimum maintenance.  Accoya also comes with a 50 year anti-rot guarantee.

Energy Efficient, Double Glazed French Doors

All our replacement timber doors come double glazed as standard to help keep your home warm during the winter months.

We can also manufacture our French doors to be single glazed or use heritage double glazing when required for listed buildings or Conservation Areas.

We offer bespoke glazing specifications and our wide range of suppliers enables us to cater for a large range of applications and styles, such as patterned, obscure, safety and laminated glass.

High Quality, Sustainable French Doors

The quality of the timber that used in your wooden French doors are of paramount importance to the lifespan and performance of your doors.

We recommend using Accoya, which is a sustainable modified wood, for your timber French doors.  Accoya is reasonably forgiving of any subsequent lack of maintenance or neglect and is designed to last a lifetime, coming with a 50 year anti-rot guarantee.

All our bespoke French doors have at least three factory-applied coats of paint comprising base-coat primer, preservative, undercoat and a white semi-gloss topcoat finish. We can also offer a large range of coloured paints, as well as bespoke plain and waxed hand coated finishes, if required, at an extra cost. Find out more about our paint and stain finishes.

We also offer a range of ironmongery options with our French doors, including polished brass, antique brass, polished chrome, and satin chrome. 

In additional to wooden French doors, we also manufacture and install complete new sash windows, casement windows, external bi-folding doors and front doors, alongside offering a draught proofing service for timber windows.
