Smartly Designed Windows in Horsham

Windows in Horsham

Window Mart offers beautifully designed windows for homes in Crawley. All our windows have been crafted to suit the UK’s unique architectural requirements, with each frame coming in 70mm deep. Our tradespeople will help you find the window that will improve your home’s security and enhance its visual appeal.

As window system specialists, we offer two types of window designs for residential properties:

  • Casement (chamfered and sculptured)
  • Vertical Slides

Choose from either one and have them modified to suit your preferences.

Sturdy PVCu Framework

Window Mart uses unplasticised Polyvinyl Chloride (PVCu) for the window frameworks. This material was chosen for its ability to withstand the common issues that result from wear and tear. Additionally, PVCu’s durability and longevity make it ideal for external architectural applications.

Cost-efficient Glazed Glass

Window Mart applies glazing units to the internal side of all windows to drive up the home’s energy efficiency rate. Glazing can deflect external heat in that it provides windows with an additional layer of tint and reflectivity. We use Heatguard® for our window glazing needs.


Double-glazed Windows

Aside from single-glazed windows, we offer double-glazing services that have been recognised by the British Fenestration Ratings Council for its energy efficiency. This service has even earned us an ‘A’ rating from the council.

Dependable Window Security

We use a variety of Homeguard™ locks and handles to secure our window systems. These smartly designed components can effectively support our multi-locking systems. Each window is tested prior to being sold to confirm its security system.

Why Choose Window Mart?

Window Mart takes home safety seriously. As such, all windows are designed to be stylish yet highly practical. We work with fully trained tradespeople who have the knowledge and expertise to create quality window systems.
