Services
Narrowboat Windows
Our narrowboat windows are crafted from toughened safety glass and aluminium frames, designed to meet E11 R43 standards. Available in standard or bespoke sizes, they offer durability and aesthetic appeal for canal boats and Dutch barges. The bonded and framed options ensure watertight seals and customisation for privacy, thermal efficiency, and ventilation.
Horsebox Windows
Horsebox windows combine strength and safety, using 5x stronger glass than standard panes. Compliant with E11 43R standards, they feature bonded or framed designs for secure installation. Options include tinted glass for sunlight protection and theft deterrence, alongside a 12-month warranty for peace of mind.
Land Rover Windows
Specialist windows for Land Rover Defender 90 and 110 models, manufactured to MOT-compliant E11 R43 standards. Available in flange, concealed flange, or bonded panoramic styles, they offer custom frame finishes and glass tints for aesthetic and functional versatility.
Glass Products
We produce toughened glass, mirrors, splashbacks, and CNC-machined items like balustrades and shower screens. Our in-house processing plant enables precise cutting, edging, and drilling, with options for fire-resistant and double-glazed units tailored to client specifications.
CNC Glass
Using advanced Denver CNC machines, we create bespoke glass components including stair balustrades, shower screens, and splashbacks with cut-outs. This technology ensures accuracy for complex shapes and sizes, enhancing both residential and commercial spaces.

Report
I needed a replacement pane of glass for a narrowboat window, as a matter of urgency. The team at Caldwells were fantastic with processing my order really quickly. After sales service absolutely top class, cannot be faulted. I will certainly continue to use Caldwells as and when required myself and would highly recommend to anyone.

Great service from Hannah. We were looking for a van window to be fitted. Caldwell's don't fit these themselves. She rang another company who in turn recommended another company that would come out and do it at our home. She then sent us a WhatsApp with all the details. I mean this is excellent service.

From the outset, the staff in the office on the telephones were extremely polite and helpful. The customer focus is excellent, and the technical team provided very accurate details and dimensions to facilitate the manufacturing of my windows to the exact measurements I gave them.
An excellent finish and they matched the other windows perfectly, making an amazing difference to the appearance of my canal boat. Caldwell's are an amazing team of people, and I highly recommend their services to anyone considering manufacturing or replacing windows. Thank you so much to every one at Caldwell's.
