Let our team recommend the perfect glazing configuration for your project.

The Ultraslim Series employs a deeper 4-9/16" frame with a refined 2-7/8" visible profile and concealed gasket system. This produces a contemporary design while maximizing the glass area for viewing, ideally matched to new construction and large window openings.

Both series deliver remarkable thermal efficiency and wide-ranging customization choices.

Our windows integrate a metal-free, dual-seal spacer system created to minimize heat transfer around the glass boundary and reduce condensation occurrence. This warm-edge spacer technology amplifies overall thermal performance and helps avoid premature seal failure, ensuring your windows perform reliably in Markham's variable climate for many years to come.

Yes, warranty coverage transfers to new owners when you sell your home. This transferable benefit adds to your property's resale value while giving future homeowners peace of mind about window quality. Coverage tiers include: full 100% coverage for the first 25-year period, then 80% manufacturer coverage (20% customer portion) during years 25-30, and 25% manufacturer coverage (75% customer portion) after year 30.

Yes, we install windows year-round, including during Ontario's winter months. Our qualified installation crews are trained and supplied to complete installations in any weather conditions while ensuring proper sealing and product function. We apply strategies to minimize heat loss in your house during window installation activities.

Condensation happens when warm, humid indoor air touches a cooler surface like window glass, prompting moisture to condense. Windows don't produce condensation; they just expose the excess humidity that's already in your home. High-performance vinyl windows with warm-edge spacer systems and proper Low-E glazing sustain warmer interior glass surfaces, substantially lowering condensation frequency. Keeping humidity levels indoors between 30-50% also helps prevent this situation.

Vinyl windows call for minimal continuing maintenance. Wipe down glass and frames periodically with mild soap and water—avoid abrasive cleaners that may cause scratching. Keep tracks clear and clean for optimal operation, and lubricate hardware occasionally. Check weatherstripping each year and ensure weep holes stay clear. Adhering to these simple steps, homeowners in Markham can trust their windows will maintain their appearance and performance for many years ahead.

Window Force windows include CSA certification establishing quality and safety conformance, and are engineered to achieve or exceed ENERGY STAR® specifications for energy efficiency. As an ENERGY STAR Partner, we produce windows supplying excellent thermal performance that cut energy consumption—essential benefits for homes navigating Ontario's seasonal temperature swings.

Not required. Windows facing various directions gain from different glass treatments. South and west exposures frequently perform optimally with Low-E coatings calibrated for winter solar heat capture while minimizing summer heat. North-facing windows generally prioritize insulating properties rather than solar concerns. Our team can identify the perfect glazing setup for every window opening to maximize energy conservation throughout your property.

Production and delivery generally take several weeks, depending on order quantity, customization elements, and current manufacturing timelines. Each window is fabricated to order at our Toronto facility, ensuring precise craftsmanship and quality control measures. We'll offer customers a specific timeline when placing orders and communicate regularly during the production phase.

Markham residents and construction professionals rely on Window Force for Canadian-produced quality, certified performance, and consistent service. Our windows meet CSA and ENERGY STAR criteria, feature a comprehensive warranty, and are manufactured locally in Toronto, ensuring consistent quality, dependable lead times, and products tailored specifically for Ontario's climate needs.

New construction windows are created for new home construction or additions where wall framing is visible at installation. These windows include a nailing fin that connects directly to structural studs before exterior siding or brick goes up. Replacement windows, on the other hand, are precision-manufactured to install into existing window openings without disturbing interior or exterior trim work, making them the optimal choice for window replacement in existing Markham homes. Window Force builds windows for both project types, and our team can advise which option best matches your project whether building new or renovating an existing structure.
