Living in Bolton means dealing with a wide range of weather—from chilly winters with biting winds across neighborhoods like Palgrave and Bolton Mills, to warm, humid summers. Choosing the right windows and doors is crucial not only for comfort but also for energy efficiency and protecting your home against the elements. That’s where our expertise as Formcorex certified installers truly makes a difference. We specialize in installing ENERGY STAR certified Formcorex windows and doors that are designed to withstand Ontario’s climate while reducing your energy bills.
Our team installs a variety of options including durable vinyl, elegant fiberglass, and classic wood frames, each selected for their insulating properties and long-term performance. For example, our Formcorex High-Performance Vinyl Windows feature multi-chambered frames and Low-E glass, which minimize heat loss during winter and keep your home cooler in summer. This translates into real savings on heating and cooling costs—something our Bolton customers consistently appreciate. One recent client in the West Bolton area reported a noticeable drop in their monthly energy bills within just a few months of upgrade.

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.
Bolton'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.
