G W S Window Systems

Established in 1983, G W S Window Systems is a family-run business based on Hayling Island, Hampshire. With over four decades of experience, we specialise in the supply and professional installation of UPVC and aluminium windows, doors, conservatories, and orangeries for both domestic and commercial clients. Our services include replacing broken or misted sealed units, full repair solutions, and bespoke design projects tailored to enhance property value and energy efficiency. We pride ourselves on offering honest advice, transparent pricing, and a no-pressure approach, ensuring every customer receives the same high standard of service regardless of project scale. Our team of fully qualified installers guarantees precision and reliability, backed by comprehensive warranties and consistently positive customer feedback. By avoiding inflated pricing and commission-based sales tactics, we deliver cost-effective solutions that prioritise long-term durability and aesthetic appeal.

Our commitment to quality extends to using locally manufactured materials, including A-rated windows with Yale security features, argon gas insulation, and low-maintenance finishes. Whether upgrading a single window or undertaking a full home transformation, we focus on creating functional, energy-efficient spaces that meet modern living demands. Our expertise in classic and contemporary designs, from Victorian conservatories to minimalist aluminium orangeries, ensures every project complements the client's lifestyle and architectural style. This dedication to craftsmanship, customer care, and innovation has solidified our reputation as a trusted local provider in the region.
