At DM Windows, we’ve spent more than two decades helping homeowners across Bristol, Bath, and surrounding areas improve their properties with high-quality windows, doors, and glazed extensions. We manufacture many of our products ourselves, right here in Bristol at our 40,000 sq ft factory site in Bishopsworth.
We offer a series of products, including the Residence Collection, beautifully crafted timber-alternative windows and doors that combine authentic period styling with modern performance. Alongside this, we manufacture a full range of uPVC and aluminium windows and doors. We off quality control, fast turnarounds, and competitive pricing. When you choose us, you’re working directly with the people who care about your home and install with the highest standards.

Our installers are fully accredited, so you can trust that every installation meets current Building Regulations.
Every project is bespoke. Whether it's a single window replacement or a full home renovation, we'll design and build exactly what your property needs.
From timber effect windows to aluminium doors, we install a huge range of home improvement products.
From heritage properties in conservation areas to modern new builds, we supply and install windows, doors, outdoor structures and glazed extensions to suit every style of home.
Our product range includes casement windows, sliding sash windows, bay and bow windows, tilt and turn windows, and flush sash windows, available in uPVC, aluminium, or as part of the premium Residence Collection (R9, R7, and R²). Our windows are available in double and triple glazing, and we also offer secondary glazing.
For doors, we offer composite front doors from Distinction Doors, aluminium bi-fold doors, French doors, stable doors, and entrance doors in both uPVC and aluminium.
Every product can be tailored with your choice of colours, glazing options, hardware, and finishes. With over 60 colours available for uPVC and any RAL colour for aluminium, your windows and doors will match your home perfectly.
Arrange A Free ConsultationWe've been installing windows and doors across the South West for over 20 years. Our team is CERTASS accredited, which means every installation complies with the latest safety, security, and energy efficiency regulations. You get full certification for Building Regulations and the peace of mind that comes with it.
We work with the industry's leading systems, Spectus for uPVC, Smart Systems for aluminium, and we're approved installers of the Residence Collection. Our partnerships with Origin, Distinction Doors, and Korniche mean you're getting products from manufacturers known for quality and innovation. But because we also manufacture in-house, we can offer shorter lead times and more flexibility than most competitors.
Whether you're in Bristol, Bath, Keynsham, Clifton, or anywhere across the surrounding areas, we're your local experts for home improvements.

Contact UsI’ve just had my bi-folds and window fitted by DM windows. They look great, the service was excellent and they took away my old patio doors and window.

Brilliant company, I can’t recommend them enough. The process from start to finish has been professional and friendly, they are super helpful and have gone above what I expected.
Helen Daw
The surveyor, office and installation team were very good. I would recommend and use them again.
Worked well and tidy. Very helpful and nothing was any trouble. Will use again for the rest if work that needs doing
Fitted new front door, frame, panel and window, great service start to finish.
