Services

uPVC Windows

Our uPVC windows combine modern insulation technology with classic aesthetics, available in casement, sash, and tilt & turn configurations. Each unit features multi-chambered profiles for superior thermal efficiency and reinforced frames for enhanced security. Homeowners benefit from reduced energy bills and noise pollution while maintaining traditional architectural styles.

Composite Doors

Manufactured with reinforced polymer skins over high-density foam cores, our composite doors offer exceptional strength and weather resistance. Available in contemporary and traditional designs with optional glazed panels and multi-point locking systems, they enhance security while improving property aesthetics and market value.

Bi-Fold Doors

Aluminium bi-fold systems create seamless transitions between indoor and outdoor spaces. Precision-engineered tracks ensure smooth operation while thermal breaks maintain energy efficiency. Custom configurations accommodate various aperture widths, with options for low thresholds and integrated drainage systems for commercial applications.

Triple Glazing

Our triple-glazed units feature two argon-filled cavities and low-emissivity coatings for maximum thermal retention. This technology reduces heat loss by 30% compared to standard double glazing while maintaining slim sightlines. Ideal for period properties requiring enhanced energy efficiency without compromising architectural integrity.

Commercial Windows

Tailored aluminium and uPVC systems for offices, schools, and public buildings. Products meet Part L building regulations with U-values as low as 1.2W/mK. Integrated blinds and bullet-resistant glass options available for healthcare facilities and educational institutions requiring both security and daylight optimisation.

We wanted to use a local company and DB Design were brilliant. Dominic was efficient and always very helpful and patient especially when we were choosing our front door! We had new windows installed too and the guys fitting them were great, very friendly, professional and tidy. Really pleased with the service and end result would definitely recommend.

Db designs fitted my final third stage Windows this year, 2021, spaced over a few years as I could afford. They are all lovely and the measuring, advice, fitting and final touches all perfect. Im delighted with the quality and the price but most of all Doms advice. One my first set of windows was to the rear, he advised a small change to ensure the new windows matched seamlessly with one existing, and when I look up Im so pleased he did, I would not have noticed until later and it would have niggled! On my last window survey, Dom suggested the kitchen window over the sink had a bottom

DB Designs replaced all our old aluminium-framed windows and patio doors with UPVC, new window boards throughout and replaced a warped wooden front door with a composite one. Dom is knowledgeable and his advice and guidance turned out to be spot on, from the type of pattern to obscure the toilet and bathroom panes, to the thickness and style of the front door. When we wanted bi-fold doors into the garden, Dom explained why this would require more cost and building work than replacement patio doors. His fitters were wonderful. Very polite, clean and tidy. There is hardly any making good to be done

We've used DB Designs in the past and had a very good experience with them. We would certainly go back to them again in the future.

Fitted windows, French doors and exterior doors on our property (March 2021). Great customer service from Dominic, who gave a lot of useful advice. No pushy double glazing hard sell and no high balling the quote, which was refreshing.
Installers were efficient and very tidy. I would definitely recommend them.
