Frequently Asked Questions

Everything you need to know about the product and billing.

Do you manufacture both double-pane and triple-pane windows for Ontario homes?

Yes. Window Force produces both double-pane and triple-pane insulated glass units at our 80,000 sq ft production facility in Concord, Vaughan. Double-pane windows deliver excellent energy efficiency for most Ontario homes, while triple-pane units provide enhanced thermal performance and noise reduction suited to regions with more extreme temperature conditions. Our team can recommend the right glazing configuration based on your location within Ontario and your project goals.

What glass and glazing options are available for Ontario window projects?

We offer a comprehensive range of glass options including Low-E coatings engineered for Ontario's climate, argon gas fills for improved insulation, tempered safety glass, laminated glass for enhanced security and noise reduction, and decorative privacy glass with a variety of textures. Each configuration can be customized to match window orientation, room use, and performance targets.

Are Window Force windows custom-built to fit any opening?

Yes. Every Window Force window is custom-manufactured to the precise dimensions of your opening. From standard residential sizes to distinctive architectural shapes, our Concord facility produces each unit to exact specifications. Ontario homeowners receive windows that fit properly, perform to specification, and integrate seamlessly with their home's design.

What distinguishes the Ultraslim Series from the Classic Series?

The Ultraslim Series features a 4-9/16" frame depth and a 2-7/8" visible profile with a concealed gasket, creating a contemporary appearance while maximizing the glass area. It is well suited for new construction and larger openings. The Classic Series uses a 3-1/4" frame depth with a traditional profile, making it an ideal choice for retrofit and replacement installations where compatibility with existing conditions matters. Both series meet ENERGY STAR standards and are fully customizable.

Can Ontario homeowners purchase windows directly from Window Force?

Yes. While Window Force primarily operates as a B2B manufacturer serving builders, contractors, and dealers, we accept direct orders from homeowners across Ontario. Contact our team for a consultation, product recommendations, pricing, and professional installation if required. Call us at 905.761.2030 or submit a request through our website.

Are financing options available for Ontario homeowners?

Yes, financing programs are available to help manage your window investment. Contact our sales team to discuss current financing options, payment terms, and eligibility requirements for your project.

What provincial rebates or incentive programs apply to window upgrades in Ontario?

Ontario homeowners replacing windows with energy-efficient products may qualify for the Canada Greener Homes Initiative, the Enbridge Home Efficiency Rebate Plus program for eligible gas-heated homes, and various local utility rebates. Eligibility requirements and available amounts vary by program; our team can provide guidance on the certifications your selected windows carry to help support rebate applications.

Does Window Force comply with the Ontario Building Code?

Yes. All Window Force products are engineered to meet or exceed the requirements of the Ontario Building Code (2024 OBC), which sets out minimum performance standards for energy efficiency, structural loading, and air and water penetration resistance. Our windows carry CSA certification and meet ENERGY STAR standards applicable to Ontario's climate zones.

What spacer technology is used in Window Force windows?

Window Force windows use a metal-free, dual-seal warm-edge spacer system engineered to reduce heat transfer along the glass perimeter and minimize condensation buildup at the edges. This technology improves overall thermal performance, helps prevent premature seal failure, and contributes to long-term reliability across Ontario's variable climate.

Is the Window Force warranty transferable when selling a home?

Yes. The warranty transfers to subsequent homeowners when you sell your property, adding value to your home and providing confidence to future buyers. Coverage is structured as follows: full 100% manufacturer coverage for the first 25 years, then 80% manufacturer and 20% customer responsibility from years 25 to 30, and 25% manufacturer and 75% customer responsibility beyond 30 years.

Does Window Force install windows year-round across Ontario?

Yes. Installation services operate throughout the year, including winter months. Our installation crews are trained and equipped to complete projects in all weather conditions while maintaining proper sealing and performance standards. We take measures to minimize heat loss during the installation process.

What causes condensation on windows, and will new windows help reduce it?

Condensation forms when warm, moisture-laden indoor air contacts a cooler surface such as window glass, causing moisture to release. The windows themselves do not create condensation; they make visible the excess humidity already present in your home. High-quality vinyl windows with warm-edge spacer technology and proper Low-E glazing keep the interior glass surface warmer, substantially reducing condensation. Maintaining indoor relative humidity between 30% and 50% also helps; when outdoor temperatures fall below -10 degrees Celsius, targeting 30% indoor RH is recommended.

How do I care for and maintain my vinyl windows?

Vinyl windows require minimal ongoing maintenance. Clean glass and frames periodically using mild soap and water, avoiding abrasive products that may scratch surfaces. Wipe sliding tracks clean for smooth operation and lubricate hardware as needed. Inspect weatherstripping annually and keep weep holes clear of debris. With basic care, your windows will maintain their appearance and performance for decades.

What certifications do Window Force windows hold?

Window Force windows are CSA certified for quality and safety compliance and engineered to meet or exceed ENERGY STAR standards for all applicable Ontario climate zones. As a Canadian ENERGY STAR Partner, we manufacture products that deliver verified thermal performance and help reduce energy consumption in Ontario homes.

Should I select the same glazing for every window in my Ontario home?

Not necessarily. South- and west-facing windows often benefit from Low-E coatings that optimize winter solar heat gain while limiting summer overheating. North-facing windows generally prioritize insulation value over solar gain. Our team can recommend the appropriate glass configuration for each opening based on orientation and room use to maximize year-round energy efficiency.

What is the typical lead time from order to delivery?

Production and delivery generally take several weeks, depending on order volume, customization requirements, and current production schedules. Every window is built to order at our Concord facility, ensuring precision and quality control. Your specific timeline is confirmed during the ordering process, and we keep you updated throughout production.

What window styles are available for Ontario homes?

Ontario homeowners have access to the complete Window Force product lineup: casement windows for maximum ventilation and airtight sealing, awning windows for weather-protected ventilation, single and double hung windows for traditional operation, single and double slider windows for compact spaces, fixed and picture windows for unobstructed views, bay and bow windows for expanded living areas, and specialty architectural shapes. All types are available in both the Ultraslim and Classic Series.

What is the difference between new construction windows and replacement windows?

New construction windows are designed for installation in homes or additions where wall framing is exposed. They feature a nailing fin that attaches directly to wall studs before exterior cladding is applied. Replacement windows are precision-built to fit existing window openings without disturbing interior or exterior trim, making them the standard choice for upgrading windows in occupied Ontario homes. Window Force manufactures windows for both applications, and our team can advise which approach suits your specific project.

Why do Ontario homeowners and contractors choose Window Force?

Window Force has been manufacturing vinyl windows at our Concord, Ontario facility since 2007. Our products are CSA certified, ENERGY STAR qualified, and backed by a comprehensive transferable warranty. We serve both the trade network and direct homeowner clients, offering custom manufacturing, reliable lead times, and products specifically engineered for Ontario's climate demands. Our 80,000 sq ft production facility allows us to maintain quality control from raw material to finished unit.
