Where Our Windows and Doors Company Began

The Belgravia Group is a premier windows and doors company dedicated to enhancing your living spaces with modern elegance and unparalleled craftsmanship. Our story began in 2011 when Mariusz and his wife Justyna founded a building and construction company that has since evolved into the dynamic enterprise you see today.

With over 20 years of industry experience, Mariusz has a deep-rooted passion for construction and glazing. As demand for our services grew, we opened a joinery in London, specialising in timber-framed glazing. To meet increasing demand, we moved our timber window and door fabrication to a workshop near the German border in Poland, where each piece is handmade with precision and care.

Expanding Our Aluminium Glazing Product Range

Recognising the growing need for aluminium glazing, we expanded our product range to include high-quality aluminium windows and doors. We partnered with reputable factories across the UK and Europe to ensure we deliver exceptional products that meet our clients’ diverse needs.

Originally operating under the name Belgravia Hardwood, we rebranded to Belgravia Windows & Doors to reflect our broader product offering more accurately. In 2020, we consolidated our operations under the name The Belgravia Group, merging with the original construction company to form a unified brand known for excellence in the glazing industry.

What truly sets The Belgravia Group apart is our exceptional on-site team. Many of our team members, including key figures like Karol and Bartek, have been with us since the inception of The Belgravia Group.

Our team’s dedication and skill make them our greatest asset, ensuring each project is completed to the highest standards.

We visited the showroom at IQ Glass and Mariusz and his team fitted our beautiful sliding aluminium doors. We had an issue with them and they came and sorted it – they are great … More guys and we love our doors. I recommend this company.

Mariusz and his team at Belgravia replaced all our sash windows, as well as some doors with beautiful and robust perfect replicas of the Victorian originals. They all fit very well, … More are easy to use and have made the house much warmer. They were installed with minimal disruption by a very pleasant team. Repairs to outside window sills were also done to the highest standard. I recommend them highly.
