About Us

At Weller Green, we specialise in the manufacture and installation of timber windows and doors. Whether you need replacement timber windows, doors, frames, or draught-proofing and overhauling services, our expert team is here to assist you.

With over fifteen years of experience, we offer high-quality bespoke products, focusing on exceptional service to our customers across London and its surrounding areas. Everything we produce is made in-house, allowing us to cater to your individual preferences. We use traditional British joinery techniques paired with only the best materials, including Accoya timber, which comes with a 50-year anti-rot guarantee.

As FENSA-registered installers, we adhere to the strictest standards for safety and performance in the industry. This certification ensures that our installations comply with building regulations and that our windows and doors meet energy regulations.
