Serving Cambridge homeowners with trusted window and door solutions, we understand how the local climate—from cold, snowy winters to warm, humid summers—demands energy-efficient, durable products. That’s why we specialize in installing Formcorex windows and doors, known for their superior thermal performance and lasting quality. As Formcorex certified installers, our trained in-house crews ensure every project meets the highest standards, backed by a lifetime workmanship warranty for your peace of mind.
Our selection includes ENERGY STAR certified windows and doors that significantly reduce heat loss during the harsh Ontario winter and minimize heat gain in the summer months. For example, our vinyl and fiberglass window options feature multi-chambered frames and double- or triple-pane Low-E glass, which can improve your home’s insulation and lower energy bills—an essential consideration for homes in neighborhoods like Hespeler and Blair. One satisfied customer in Preston recently shared how their new fiberglass windows helped cut their heating costs by nearly 15% last winter.
Custom Contracting is Ontario's exclusive provider of FoamCoreX™ - the most advanced foam-filled window technology that eliminates air pockets and thermal bridging for maximum energy efficiency.

Traditional windows have hollow chambers in their frames that allow air to circulate, creating thermal bridging and energy loss. FoamCoreX™ technology fills every chamber with high-density polyurethane foam, creating a continuous thermal barrier that revolutionizes window performance.
Custom Contracting is the only certified FoamCoreX™ installer in Ontario, ensuring you get authentic technology with factory-trained installation and full warranty protection.
Cambridge's rich tapestry of architecture calls for a diverse range of window styles. Whether you reside in a historic property or a contemporary family home, our extensive collection offers designs that perfectly blend with your property's unique character.
