uPVC Windows
Our uPVC windows combine thermal efficiency with security features, offering casement, sash, and tilt-and-turn options. Available in multiple colours and woodgrain finishes, these windows reduce energy bills while maintaining aesthetic consistency with property styles. The lead-free profiles and multi-point locking systems ensure durability and enhanced security for Hampshire homeowners.
Composite Doors
Solidor-approved composite doors provide superior thermal insulation and security. These doors feature reinforced frames, multi-locking systems, and customisable glazing options. The durable finish resists weathering, maintaining aesthetic appeal while offering exceptional energy efficiency and security enhancements for residential properties across Surrey and Hampshire.
Conservatories
Our uPVC conservatories create year-round living spaces with energy-efficient glazing and insulated bases. Offering lean-to, Edwardian, and P-shaped designs, these extensions incorporate modern roofing systems for optimal thermal performance. The modular Durabase construction ensures quick installation while maintaining structural integrity and aesthetic compatibility with existing architecture.
Aluminium Windows
Slimline aluminium windows deliver contemporary aesthetics with exceptional durability. These corrosion-resistant frames accommodate large glass areas for maximum natural light. The thermally broken profiles improve insulation while maintaining sleek sightlines, making them ideal for modern properties and heritage renovations requiring slimline period-appropriate windows.
Roofline Renewal
Our UPVC roofline solutions include fascias, soffits, and guttering that enhance property aesthetics and thermal performance. The low-maintenance system prevents water ingress while improving insulation. Customisable colour options ensure seamless integration with existing architecture, providing long-lasting protection against weather damage and reducing energy consumption for Surrey and Hampshire homes.

Had all our windows and doors replaced by Hart over the years and always had great service and great quality windows. Theyre a great team so installation is quick and they take great care to tidy up and not leave a mess.

Walked into shop and said I was desperate to find someone to fit double French doors, they came back quickly with a quote and sent over surveyor promptly but surveyor could not confirm whether there was a lintel (surely that is the purpose of the surveyor visit?). When I rang for a quote including a lintel installation this was not provided and on a follow-up call I was told they were waiting for the builder to confirm a price, but then never heard anything further. If they are not interested in the job why can they not be honest. I would save yourself the bother and avoid this company and go somewhere

Came by our place to replace the hinges on a couple of windows. When leaving the house the person doing the job noticed our front door wasn't opening very well, which had been the case for years. Without charging anything extra he repaired it in a couple of minutes. Also extremely polite and pleasant throughout all the contacts I have made with them, but especially the person that came to our house.

I had broken hinges on my 15+ year old double glazing. One firm couldn't fix it, one didn't work in this area and another wanted to replace the windows. The lovely knowledgeable gentleman from Hart Windows looked, said what was needed and the cost very reasonable, they are fixed and as good as new. Thoroughly trustworthy!

This firm has the worst customer service ever. Measurement quick, 11 days and a phone call to get a price. Still no paper quote as promised three days ago! Avoid.
