Upgrade your home with energy-efficient replacement windows and beautiful entry doors. Reduce energy costs, increase comfort, and boost curb appeal.
Custom Contracting has been installing replacement windows and doors in Hamilton for over 25 years. We're an ENERGY STAR® certified partner and authorized dealer for leading manufacturers including Pella, Andersen, and North Star.
Our expertise spans all window styles—casement, double-hung, awning, slider, bay, bow, and picture windows. For doors, we install entry doors, storm doors, patio doors (sliding and French), and garage doors. We handle both new construction and replacement projects.
Hamilton's climate extremes make window efficiency crucial. Old single-pane or failing double-pane windows can account for 25-30% of your home's heat loss in winter. They also let in excessive heat in summer, overworking your AC.
Modern triple-pane windows with Low-E coatings and argon gas filling can reduce heat transfer by up to 50%. Many Hamilton homeowners see $300-$500 annual savings on heating and cooling after upgrading their windows.
Proper installation is as important as window quality. We use the "European" or brickmould replacement method for a completely weather-tight seal. Every window gets spray foam insulation in the gaps, proper shimming for square operation, and exterior caulking with premium polyurethane sealant. Our installations meet or exceed Ontario Building Code requirements.

Window prices in Hamilton range from $300-$1,200 per window installed, depending on size, style, and features. A typical Hamilton home with 10-15 windows costs $5,000-$15,000 for a complete replacement. Triple-pane and specialty windows cost more. We provide free in-home estimates.
For Hamilton's climate, we recommend triple-pane windows—the extra pane significantly reduces heat loss in our cold winters. Triple-pane costs about 15-20% more but pays back in energy savings within 5-7 years. They also reduce noise noticeably.
Most window replacements take 1-2 days for a typical Hamilton home. We install 8-12 windows per day with our experienced crews. Your home remains secure and weather-tight throughout—we never leave openings overnight.
We offer a lifetime workmanship warranty on all window installations. Manufacturer warranties vary: most vinyl windows have lifetime warranty on glass seal failure, hardware warranties of 10-20 years. We handle all warranty claims for you.
