Services
Composite Doors
Our composite doors combine durability with advanced security features, including PAS23/PAS24 certification and multi-point locking systems. Designed for thermal efficiency, these doors reduce energy bills while offering bespoke options for glass, colour, and hardware. Ideal for enhancing home security and aesthetic appeal.
Energy Efficient Windows
Energy-efficient UPVC windows utilise Planitherm glass to reflect heat inward, achieving U-values as low as 0.8 W/mK. These windows eliminate condensation, reduce draughts, and lower energy costs by up to 25% compared to standard double glazing, ensuring year-round comfort.
Conservatory Roofs
We install thermally efficient conservatory roofs with 28mm double-glazing and low-threshold systems. These structures maximise natural light while maintaining optimal temperature control, ideal for extending living spaces with modern, durable materials.
Porch Installations
Custom-designed porches enhance home aesthetics and protect against the elements. Constructed with durable UPVC or composite materials, our porches offer weatherproof solutions with optional glass panelling and colour-matched finishes for seamless integration.
French Doors
French doors provide elegant access to gardens with thermally sealed frames and multi-point locks. Available in white, rosewood, or antique oak finishes, they feature easy-glide systems and low thresholds for accessibility and energy efficiency.

Report
Excellent I would definately recommend this company. Had new windows and French doors fitted today they cleared away any mess and all the old Windows. Dan and Josh worked non stop all day and have done a brilliant job we are well pleased. Had a cowboy to fit two windows at the front a few years ago wish I had known about Ainsworth Windows then it would have saved me a lot of disappointment. If your thinking about Windows and doors give them a call you wont regret it.

We've just had a lovely new back door fitted. Really good price, didn't have to wait long between ordering and installation and when we thought there was a problem (Which it turns out there wasn't) he came round the next day to check. Definitely recommend and would use again. Thank you

Thankyou Daniel and colleague for another cracking job today. I'm really pleased with my new patio doors. Wouldn't go anywhere else.
