Oshawa's housing stock reflects its long industrial heritage — from early-20th-century workers' homes near the city core to post-war suburbs and modern developments in the north end. Each property type has distinct window requirements. Window Force manufactures every unit to your exact dimensions at our 80,000 sq ft Ontario facility, including casement, awning, hung, slider, picture, bay, bow, and custom architectural shapes.

Our team works with builders, contractors, and homeowners to ensure the right product and customization for every project.

New Construction Windows

Oshawa's northern growth corridor continues to bring new residential construction to the city. For new builds with exposed framing, the Window Force Ultraslim Series provides a 4-9/16" frame with a narrow 2-7/8" visible profile, delivering generous glass areas and a contemporary look.

The optional nailing fin enables direct stud attachment before exterior cladding is applied — a dependable installation approach for builders and contractors.

Oshawa has a large inventory of mid-century and late-century homes where windows have reached the end of their practical lifespan. Our Classic Series addresses this head-on: each unit is precision-manufactured to fit existing openings, with a 3-1/4" frame depth designed for retrofit compatibility — no changes to interior or exterior trim needed.

Professional installation is available through our network of dealers and contractors.

Lake Ontario's proximity moderates winter extremes in Oshawa but also introduces moisture-laden air and wind exposure along the waterfront.

Frequently Asked Questions

Everything you need to know about the product and billing.

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

Yes. Window Force produces both double-pane and triple-pane insulated glass units at our Toronto manufacturing facility. Double-pane windows deliver excellent energy efficiency suitable for most Oshawa residences, while triple-pane options provide enhanced thermal performance and superior noise reduction, particularly beneficial for homeowners seeking maximum insulation during Ontario's cold winters. Our specialists can recommend the optimal glazing configuration for your property.

What glass and glazing options can I choose for my Oshawa window project?

We provide an extensive selection of glass options including energy-efficient Low-E coatings, argon gas fills between panes, tempered safety glass, laminated glass for security and sound dampening, and decorative privacy glass featuring artistic textures. Each glass configuration can be tailored to your performance needs and the specific orientation of windows in your home.

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

Absolutely. Every Window Force window is custom-manufactured to match your exact opening dimensions. From standard sizes to distinctive architectural shapes, our 80,000 sq ft Toronto production facility crafts each unit to precise specifications. Oshawa homeowners receive windows that fit perfectly, perform optimally, and complement their home's architectural style.

What distinguishes the Ultraslim Series from the Classic Series?

The Ultraslim Series is designed with a deeper 4-9/16" frame and a narrower 2-7/8" visible profile featuring a hidden gasket. This creates a contemporary appearance while maximizing the glass viewing area that is well-suited for new construction and expansive openings. The Classic Series provides a time-tested 3-1/4" frame depth with a traditional profile, making it an excellent choice for retrofit and replacement installations in existing homes in Oshawa, ON. Both product lines deliver outstanding thermal efficiency and extensive customization possibilities.

Can homeowners purchase windows directly from Window Force?

Yes. Although Window Force operates primarily as a B2B manufacturer serving builders, dealers, and contractors, we also accept direct orders from homeowners in Oshawa and throughout Southern Ontario. Reach out to our team for a personalized consultation, product recommendations, pricing, and installation options if required.

Are financing programs available for window purchases?

Yes, financing options are available to help homeowners manage their window investment. Please contact our sales team to learn about current financing programs, payment terms, and qualification requirements for your specific project.

What spacer technology is used in Window Force windows?

Our windows incorporate a metal-free, dual-seal spacer system engineered to minimize heat transfer along the glass perimeter and reduce condensation buildup. This warm-edge spacer technology enhances overall thermal performance and helps prevent premature seal failure, ensuring your windows perform great in Oshawa's variable climate for years to come.

Can I transfer the Window Force warranty if I sell my Oshawa home?

Yes, our warranty transfers to new homeowners when you sell your property. This transferability adds resale value to your home and gives future owners confidence in the windows' quality. Coverage is structured as follows: full 100% coverage during the first 25 years, then 80% manufacturer coverage (20% customer responsibility) from years 25-30, and 25% manufacturer coverage (75% customer responsibility) beyond 30 years.

Does Window Force install windows during winter months?

Yes, our installation services operate year-round, including throughout Ontario's winter season. Our skilled installation crews are trained and equipped to complete installations in all weather conditions while maintaining proper sealing and product performance. We implement measures to minimize heat loss in your house during window installation process.

Why does condensation form on windows, and will new windows help reduce it?

Condensation develops when warm, moisture-laden indoor air meets a cooler surface like window glass, causing the moisture to condense. The windows themselves don't create condensation as they simply make visible the excess humidity present in your home. That said, premium vinyl windows equipped with warm-edge spacer systems and proper Low-E glazing keep the interior glass surface warmer, substantially reducing condensation occurrence in homes. Keeping indoor humidity levels between 30-50% further helps prevent this issue.

How should I care for and maintain my new vinyl windows?

Vinyl windows demand very little ongoing maintenance. Periodically clean the glass and frames using mild soap and water - steer clear of abrasive products that may scratch surfaces. Keep sliding tracks clear and wiped down for smooth operation, and apply lubricant to hardware as necessary. Check weatherstripping each year and ensure weep holes stay unobstructed. Following these simple steps, homeowners in Oshawa can expect their windows to retain their beauty and functionality for many years.

What certifications and standards do Window Force windows meet?

Window Force windows carry CSA certification confirming quality and safety compliance, and are engineered to meet or surpass ENERGY STAR® requirements for energy efficiency. As an ENERGY STAR Partner, we manufacture products delivering excellent thermal performance that help reduce energy consumption which are important benefits for homes facing Ontario's seasonal temperature extremes.

Should every window in my home have identical glazing?

Not necessarily. Windows facing different directions benefit from different glass configurations. South and west-facing windows may perform best with Low-E coatings optimized for winter solar heat gain while limiting summer heat. North-facing windows typically prioritize insulation properties over solar considerations. Our team can suggest the ideal glazing setup for each window opening to maximize energy savings throughout your house.

How long does it take from placing an order to receiving my windows?

Production and delivery generally require several weeks, varying based on order volume, customization details, and current manufacturing schedules. Every window is built to order at our Toronto facility, guaranteeing precision craftsmanship and quality control. We'll provide customers with a specific timeline during the ordering process and maintain communication throughout production.

Does Window Force offer installation, or is it supply-only?

Window Force functions primarily as a manufacturer and supplier, partnering with builders, dealers, and contractors across Ontario and beyond. However, professional installation services are also available for projects in and our broader service area. Whether you need windows supplied to your contractor or require complete installation support, contact our team to determine the best solution for your project.

Getting started is straightforward. Request a quote through our website or call us directly at 905.761.2030. Our team will help you select window styles suited to your Oshawa home, confirm measurements and specifications, and walk you through customization options including colours, glass types, grills, and hardware.

Homeowners have access to the complete Window Force product lineup, including casement windows for excellent ventilation and sealing, awning windows ideal for weather protection, single and double hung windows for traditional operation, single and double slider windows for compact spaces, picture and fixed windows for maximum views, bay and bow windows for expanded living space, and custom architectural shapes.

Our windows meet CSA and ENERGY STAR standards, come backed by a comprehensive warranty, and are manufactured locally in Toronto, ensuring consistent quality, reliable lead times, and products engineered specifically for Ontario's climate demands.

What distinguishes new construction windows from replacement windows for Oshawa projects?

New construction windows are intended for newly built homes or room additions where wall framing remains exposed during installation. These windows include a nailing fin that secures directly to the structural studs before siding or brick is installed. Replacement windows, by contrast, are precision-manufactured to slide into existing window openings without disrupting the interior or exterior trim surrounding them, making them the preferred choice when upgrading windows in established Oshawa homes. Window Force produces windows for both scenarios, and our specialists can advise which solution best fits your project depending on whether you're constructing new or retrofitting an existing residence.
