Window Force manufactures custom vinyl replacement windows at our Ontario production facility for homeowners, builders, dealers, and contractors across Toronto and Southern Ontario. Every unit is built to order, CSA-certified, and engineered to meet or exceed ENERGY STAR® efficiency standards — giving you factory-direct access to the same windows installed in thousands of Ontario homes each year.
Whether you’re upgrading aging windows in an established home or sourcing replacement units for a renovation project, our products are designed for precise fit, long-term thermal performance, and reliable operation through Ontario’s full range of seasonal conditions.
Replacement windows are custom-built units designed to fit directly into your existing window openings without altering the surrounding wall structure, interior trim, or exterior cladding. Unlike new construction windows, which attach to exposed wall framing with a nailing fin before siding or brick is applied, replacement windows slide into the current frame opening and are secured in place, making them the standard solution for upgrading windows in occupied homes.
This approach minimizes disruption to your home during the upgrade process. There’s no need to remove interior casings, disturb exterior finishes, or repair drywall after the work is done. For most homeowners in Toronto and across Ontario, replacement windows offer the most practical and cost-effective path to improved energy efficiency, comfort, and curb appeal.
The distinction matters when planning your project. Replacement windows are precision-manufactured for existing openings and install from inside the home with minimal structural work. New construction windows are intended for new builds or additions where wall studs are exposed, and they include a nailing fin for attachment to the framing before exterior cladding goes on. Window Force manufactures both types — your dealer or contractor can advise which approach fits your specific project.
Within the replacement category, there are two installation methods. A retrofit (or insert) installation fits the new window inside the existing frame, preserving the original frame structure. This is the faster, less invasive option and works well when the existing frame is in sound condition. A full-frame (or brick-to-brick) replacement removes the entire old window including the frame, allowing the new window to be installed directly into the rough opening. This method is more involved but provides the opportunity to inspect and address any hidden damage, improve insulation around the opening, and in some cases accommodate a larger glass area.
A window replacement is one of the most impactful upgrades you can make to an existing home. The benefits extend well beyond aesthetics:
Modern vinyl windows with Low-E coatings, argon gas fills, and warm-edge spacer systems substantially reduce heat transfer through the glass. In Ontario’s climate — where winters regularly drop well below −10°C and summers bring sustained humidity — this translates to measurable savings on heating and cooling costs. ENERGY STAR® certified windows, like those manufactured by Window Force, are independently verified to meet strict efficiency thresholds.
Eliminating drafts, cold spots, and temperature fluctuations near windows creates a more consistent indoor environment. Rooms that were previously uncomfortable during extreme weather become usable year-round.
Multi-pane windows with proper sealing significantly dampen exterior noise. For Toronto homeowners near busy streets, transit corridors, or construction activity, this can be a meaningful quality-of-life improvement.
Updated windows are one of the first things prospective buyers and home inspectors notice. New, energy-efficient windows signal a well-maintained property and can positively influence resale value and buyer perception.
Vinyl replacement windows require no painting, staining, or refinishing. Periodic cleaning with mild soap and water is all that’s needed to maintain their appearance and function for decades.
Modern windows feature multi-point locking mechanisms and reinforced frames that are significantly more resistant to forced entry than older single-latch designs. Laminated or tempered glass options add another layer of protection.
Low-E glass coatings filter out a significant portion of ultraviolet radiation, helping to protect interior furnishings, flooring, and artwork from fading and sun damage over time.
Window Force manufactures a complete range of vinyl window styles, each available as a replacement unit custom-built to your exact opening dimensions. The right style depends on the room, the wall orientation, ventilation needs, and your home’s architectural character.
Casement
Hinged on one side and operated with a crank mechanism, casement windows swing outward to provide full top-to-bottom ventilation. When closed, the sash compresses against the frame for an exceptionally tight seal — making them one of the most energy-efficient operable window styles available.
Awning
Top-hinged and opening outward from the bottom, awning windows allow ventilation even during light rain. They’re commonly used in bathrooms, kitchens, and basements, or paired with fixed windows for a combination of light and airflow.
Single Hung
A traditional design where the bottom sash slides up while the top sash remains fixed. Single hung windows offer a classic appearance, reliable operation, and cost-effective performance for bedrooms, hallways, and standard openings.
Double Hung
Both the upper and lower sashes operate independently, providing flexible ventilation options. Many double hung models feature tilt-in sashes for easy cleaning from inside — especially practical for upper-floor windows.
Single Slider
One sash slides horizontally while the other remains stationary. Sliders are ideal for wider openings and rooms where outward-swinging windows aren’t practical, such as along walkways or patios.
Double Slider
Both sashes slide horizontally, offering maximum ventilation flexibility for wide openings. Double sliders provide a clean, modern look and efficient space utilization.
Shapes
Custom geometric shapes — including arches, circles, trapezoids, and triangles — manufactured to match unique architectural features. These fixed units are typically installed above doors or standard windows as decorative accents.
Bay and Bow
Projecting outward from the wall, bay (three-panel) and bow (four or more panels) configurations create additional interior space, architectural interest, and panoramic views. They’re a dramatic upgrade for living rooms, dining areas, and primary bedrooms.
Picture Fix / Slim Fix
Non-operable windows designed to maximize natural light and views. With no moving parts, they offer the tightest possible seal and the most glass area for any given opening. Often used as centrepieces flanked by operable units.
Featuring a 4-9/16″ frame depth with a narrow 2-7/8″ visible sightline and concealed gasket, the Ultraslim Series delivers a contemporary, streamlined profile that maximizes glass area. Originally developed for new construction, its deeper frame also makes it an excellent choice for full-frame replacement projects where the entire old window assembly is being removed. The result is more glass, more light, and a clean modern aesthetic.
Built on a proven 3-1/4″ frame depth with a standard sightline profile, the Classic Series is purpose-built for retrofit replacement projects. Its dimensions are specifically calibrated for compatibility with existing frame openings in Ontario homes, making it the go-to choice for insert-style replacements where the original frame remains in place. Dependable thermal performance, a familiar look, and broad installation compatibility.
Not all replacement windows are built to the same standard. When evaluating options for your Toronto or Ontario home, these are the features and certifications that separate quality products from the rest:
Multi-chamber vinyl (uPVC) frames provide superior thermal insulation compared to aluminum and require none of the ongoing maintenance that wood demands. Look for fusion-welded corners — where the frame pieces are melted together rather than screwed or glued — as this creates a stronger, more water-tight joint that resists air and moisture infiltration over the life of the window.
Double-pane insulated glass is the baseline for Ontario homes, with triple-pane configurations offering enhanced thermal and acoustic performance. Low-E (low-emissivity) coatings reflect heat energy while admitting visible light, and argon gas fills between panes slow heat transfer through the glass unit. The combination of these technologies determines your window’s U-factor (heat loss rating) and Solar Heat Gain Coefficient (SHGC) — the two metrics that matter most for energy efficiency.
The spacer bar separating the glass panes is a critical but often overlooked component. Metal spacers conduct heat and create cold edges that promote condensation. Warm-edge spacer systems — like the metal-free, dual-seal spacers used in Window Force windows — minimize heat transfer at the glass perimeter, reduce condensation risk, and help prevent premature seal failure.
CSA certification confirms the window has been independently tested for structural integrity, air tightness, water penetration, and wind resistance. ENERGY STAR® certification means the product meets or exceeds Natural Resources Canada’s efficiency standards for your climate zone. Both certifications are meaningful third-party validations of quality — not marketing claims. Window Force products carry both.
A comprehensive warranty reflects the manufacturer’s confidence in their product. Look for coverage that addresses the sealed glass unit, frame, hardware, and finish separately, with clearly stated terms. Transferable warranties add resale value to your home. Window Force offers a tiered Lifetime Warranty: 100% coverage for the first 25 years, 80% manufacturer / 20% customer from years 25–30, and 25% manufacturer / 75% customer beyond 30 years — fully transferable to subsequent homeowners.
The cost of replacement windows varies depending on window style, size, glazing configuration, and the scope of the installation. The table below provides general price ranges to help you budget your project. These are estimated per-window costs for standard sizes and do not include installation.
| Window Type | Avg. Price Min | Avg. Price Max |
|---|---|---|
| Casement window | $390 | $950 |
| Awning window | $390 | $950 |
| Single or double hung | $270 | $850 |
| Sliding window | $260 | $790 |
| Bay or bow window | $2,500 | $6,000 |
| Picture / fixed window | $250 | $700 |

Most replacement window companies in Toronto are retailers or installers who source products from third-party manufacturers. Window Force is the manufacturer. When you choose Window Force — whether through a dealer, contractor, or directly — you’re getting windows built at our 80,000 sq ft Ontario facility by the same team that controls every step from raw material to finished product.
This matters because it means consistent quality control, the ability to produce truly custom sizes and configurations without outsourcing, shorter lead times compared to imported products, and pricing that reflects factory-direct economics rather than multi-layer distribution markups.

VitalyHigh-quality vinyl replacement windows typically last 25 to 30 years or more with basic maintenance. The sealed glass unit, frame integrity, and hardware all contribute to the overall lifespan. Window Force backs our products with a comprehensive Lifetime Warranty — 100% coverage for the first 25 years, with continued tiered coverage beyond that.
Savings vary depending on the age and condition of your current windows, your home’s overall insulation, and the glazing configuration you choose. According to Natural Resources Canada, replacing single-pane windows with ENERGY STAR® certified units can reduce window-related energy loss significantly. Most homeowners notice an immediate improvement in comfort and a measurable reduction in heating and cooling costs.
Retrofit (insert) installation places the new window inside the existing frame, which is faster and less invasive. Full-frame (brick-to-brick) replacement removes the entire old window including the frame, allowing inspection of the underlying structure and typically providing a slightly larger glass area. The right method depends on the condition of your existing frames and the scope of your project.
In most cases, a straightforward window replacement using the same size opening does not require a building permit in Toronto. However, if you’re changing the size or location of window openings, or if structural modifications are involved, a permit may be required. Check with your local municipality or building department to confirm requirements for your specific project.
Yes. Professional window replacement can be performed year-round in Ontario, including during winter months. Experienced installers work efficiently to minimize the time each opening is exposed, and modern installation techniques ensure proper sealing regardless of outdoor temperature. Window Force windows and installation coordination are available throughout all seasons.
Low-E (low-emissivity) glass has a microscopically thin metallic coating that reflects heat energy while allowing visible light to pass through. In winter, it helps keep heat inside your home; in summer, it reduces solar heat gain. For Ontario’s climate, Low-E coatings are highly recommended and are standard on most ENERGY STAR® qualified windows.
Double-pane windows provide excellent energy efficiency for most Ontario homes and represent the most common choice for residential replacement. Triple-pane windows offer superior thermal performance and enhanced noise reduction, making them ideal for very exposed locations, north-facing walls, or homeowners who prioritize maximum insulation and sound dampening. Our team can help you determine which configuration makes the most sense for each window opening in your home.
Yes. Every Window Force window is manufactured to your exact opening dimensions at our Ontario facility. We do not sell stock sizes — every unit is built to order, ensuring precise fit and optimal performance.
Manufacturing lead time is typically several weeks depending on order size and customization. The on-site replacement itself varies by project scope: a few windows can often be completed in a day, while a full-home project may take two to three days. Your dealer, contractor, or our team will provide a specific timeline during the planning process.
