Steel Doors
Crafted for longevity, our steel doors combine double-glazing with hand-finished patinas to enhance security and weather resistance. Ideal for modern and heritage properties, they offer enduring style while meeting bespoke aesthetic and functional requirements through precise manufacturing and installation.
Steel Windows
Slim-framed steel windows maximise natural light while ensuring energy efficiency and durability. Each unit is precision-engineered to complement architectural styles, featuring customisable finishes that maintain timeless appeal alongside modern thermal performance standards for residential and commercial spaces.
Refurbishment
Specialists in reviving original steel windows and doors, we combine heritage preservation with upgrades like improved insulation and security. Skilled artisans repair, refinish, and enhance existing installations, extending their lifespan while retaining historical authenticity and structural integrity.
Thermally Broken Windows
Thermally broken steel windows incorporate advanced insulation barriers within frames to prevent heat transfer. This innovation maintains aesthetic continuity with traditional designs while achieving year-round comfort and energy efficiency for both new builds and heritage renovations.

Designed for open-plan spaces, these doors feature minimalist profiles that allow light flow without compromising style. Customisable configurations enable seamless integration into interior layouts, offering acoustic separation and visual continuity through precision-engineered steel construction.

Absolute rubbish service. First contact made in January this year, after repeated calls and emails finally got the quote, measured up- signed the t and c and paid required deposit in March. Still waiting 6 months later for window to arrive/be fitted. Multiple calls and promises to get back not answered. No idea why anyone would consider using this company

REVIEW OF COTSWOLD CASEMENT CO.
By: Ivan Semenenko
I have just completed my new house which I wanted it to fit within traditional Cotswold country houses but with complementary modern and ancient features. The house structure has largely used reclaimed Cotswold, "honey", stone, mullions etc and reclaimed oak timbers- some of these have been dated as over 300 years old. I wanred the windows and doors to be as invisible as possible so plumbed for large uninterupted doors and windows set into metal frames as slender as possible. So most windows and doors were around 900mm X 2000mm with no cross

Having got 7 different quotes from similar companies I chose Cotswold Casement as they were the cheapest, they were local and my communication with Christine was brilliant. The service was excellent from the guidance on the different types of windows to a walk around the workshop to the installation of my new windows and doors. The overall experience was flawless and I am looking forward to working with this company again in the near future. They provide class, beauty and that timeless look to an affordable price.
