Our Promise

Why Homeowners and Building Contractors Choose Us

Made to Measure, Never Off the Shelf

Whether you’re restoring a period home or managing a new-build project, every window and door we make starts with your measurements and your property’s architecture. We’re the manufacturer, not a middleman, so you get straight answers from the joiners who actually build your frames.

Joinery That’s Built to Last

Carefully selected timber, precision joinery and long-lasting finishes give our timber windows & doors decades of reliable service. And unlike plastic alternatives, a timber frame can be repaired and refinished rather than ripped out and replaced.

One Team, From Survey to Fitting

The people who measure your home are the same people who design, build and install your timber windows and doors. For homeowners, that means no surprises. For building contractors, it means one reliable point of contact, clear quotes and a tidy, well-organised installation.

Survey Free When You Order

For period properties and homeowners who value character, yes. Timber gives a natural, authentic look, can be repaired and repainted rather than replaced, and is a more sustainable choice when responsibly sourced. uPVC is usually cheaper upfront, but it can’t be refinished or repaired in the same way.

Well-made wooden windows can last for many decades. The secret is regular maintenance and repainting, which keeps the timber protected and the frames working smoothly year after year.

Quality factory-applied finishes typically last several years before a maintenance coat is needed. Exposed or south-facing windows may need attention sooner, while sheltered ones can go longer.

Often, yes. Requirements vary by council and property, so it’s worth checking with your local planning authority early. To make the process easier, we can supply like-for-like specifications and drawings to support your application.

Yes. We can closely match your existing profiles, glazing bar patterns and proportions, so your new windows look as if they’ve always belonged to your home.

Yes, we provide a complete supply-and-fit service. As timber window manufacturers in London, we look after every step in-house, from the first survey and manufacture through to expert wooden window installation.

Yes. Our timber doors include front doors, French doors, bi-fold doors and stable doors, each made to order to complement your home and your new windows.
