History
In 2024 our production and technology teams achieved a breakthrough by developing a solution that significantly lowers the U-value of timber windows.
We now offer timber sash and casement windows with a U-value below 1, a milestone once considered unattainable.
In 2022 we proudly became the official distributor of Velfac and Rationel products, further enhancing our offerings.
In 2020 we relocated to a new office and launched a stunning showroom in South Wimbledon to display our complete product range.
In 2018 we diversified our product portfolio by introducing internal steel doors and partitions.
In 2014 we expanded our offerings to the commercial sector, providing high-quality aluminium glazing solutions.
In 2012 we changed our company’s name to DM Window Solutions.
In 2010 we tightened our business relationships with Wimbledon Builders Merchants, IBB Building Wholesale in Park Royal, A Builders Store in Brentford, DoBuild Direct in Kenley and many more.
All retailers have showrooms with a range of our products displayed there.
From 2010 we widened our windows and doors offer by aluminium products including flat roof skylights.
Since 2009 we offer premium quality windows and doors in timber.
On top of that, we are especially proud of undertaking new and unique projects involving bespoke glass and aluminium structures.
Since 2006 we operate as a Limited Liability Company offering much wider range of services.
