Custom Vinyl Windows,
Built to Your Exact Specifications

Window Force has manufactured custom vinyl windows at its Concord, Ontario facility since 2007 — over 18 years of production experience in an 80,000 sq ft plant built specifically for custom uPVC fabrication.

Exact-Size
Manufacturing

Every window leaves the Concord facility built to the exact dimensions of the opening it is made for. There are no stock sizes and no off-the-shelf units adapted to fit. Builders supplying multi-unit developments, contractors retrofitting established homes, and homeowners upgrading individual openings all receive the same manufacturing process: every frame cut, welded, glazed, and checked against the specification submitted.

Engineered for
Every Application

All window types are available across two product series: the Ultraslim Series, with its 2-7/8" visible profile and 4-9/16" frame depth for new construction and larger openings; and the Classic Series, with a proven 3-1/4" frame depth suited to replacement and retrofit conditions. Both series are manufactured from lead-free uPVC with fusion-welded corners, fitted with a dual-seal metal-free warm-edge spacer, and produced to CSA certification standards. Window Force holds ENERGY STAR Partner status and manufactures to NAFS-11 performance requirements.

I am the principal of Window Depot Canada, a windows-and-doors sales and installation company. We have had an account with Window Force since 2018. After new management took over in 2023, Window Force's results have been remarkable. The company dramatically increased production and developed new products that are in high demand in the industry. One of them is a slim-profile casement window that is so popular on the market. The next will be a triple glass slider window. As a result, they moved to a new location with space that greatly exceeded the previous one and became the fastest-growing window company in Ontario. Their leadership, professionalism, and dedication to quality should give you confidence in their work. Product delivery is always on time, customer service is fast and efficient, and communication is very easy. The business owner, Sergey, possesses great knowledge, honesty and professionalism that inspires those around him to strive for excellence.

Window Force has been a true partner to our company, and we fully stand behind them. The quality of their work is outstanding, but what really sets them apart is how quickly they deliver on orders. Having worked with other window manufacturers in the past, I can say the experience isn't even comparable. Window Force operates on a completely different level in terms of reliability and efficiency. Whether it's a small order of three windows or a large project with hundreds, they handle everything with the same level of care and professionalism.

Thank you to Sergey, Anthony, and Jonathan — I know I can always rely on you.

I've worked with manufacturers across the industry for many years. While we produce our own line of windows, there are projects — particularly custom cottage builds — where we partner with Window Force for specialty configurations, oversized openings, and architectural shapes that call for a manufacturer who can execute precisely to spec. What stands out about Window Force is the consistency. Lead times are reliable, the build quality matches what was ordered, and the communication is straightforward — which matters when you're coordinating a custom project with a tight installation window. Their facility has the capacity to handle the work, and Sergey and his team genuinely care about the details, whether it's a one-off shape or a larger custom run. For any builder or contractor looking for a manufacturing partner who can deliver on custom and architectural requirements without the runaround, Window Force is a company I'm happy to put my name behind.

Frequently Asked Questions

Everything you need to know about the product and billing.

Are all Window Force windows custom-made to size?

Yes. Every window produced at the Concord facility is built to the exact rough-opening dimensions submitted with the order. Window Force does not manufacture stock sizes or pre-built inventory for retail distribution. Each unit is cut, welded, and glazed to specification before shipment.

Can I buy custom windows directly from Window Force as a homeowner?

Yes. While Window Force operates primarily as a B2B manufacturer serving builders, dealers, and contractors, the company also accepts direct orders from homeowners. Contact the team for product selection, sizing guidance, and pricing. For projects that require installation, Window Force can connect buyers with authorized installation partners.

What materials are Window Force windows made from?

Frames and sashes are manufactured from lead-free uPVC (unplasticized polyvinyl chloride). All corners are fusion-welded for structural integrity and long-term weatherproofing. The spacer system is a dual-seal, metal-free warm-edge design that minimizes heat transfer at the glass perimeter and reduces the likelihood of edge condensation.

What is the difference between a custom window and a standard window?

Standard windows are produced in fixed sizes and stocked by retailers for general use. Custom windows are manufactured to the exact dimensions of a specific opening, which eliminates shimming, adapted frames, and the performance gaps that come with approximate sizing. For replacement projects with non-standard openings, or new construction where design calls for specific proportions, custom manufacturing is the correct approach.

How much does a custom vinyl window cost in Canada?

Pricing depends on size, profile series, glass configuration, colour selection, and order volume. Window Force supplies both individual homeowner orders and large builder volumes, with pricing structured to each project type. Contact the team directly for a project-specific quote.

Are Window Force windows certified for Canadian climate zones?

Yes. Window Force holds ENERGY STAR Partner status and manufactures windows to meet the requirements of the Canadian ENERGY STAR program, which sets performance thresholds across climate zones. All windows also carry CSA certification and are rated to NAFS-11 structural and performance standards. For specific ER ratings, U-factor, and SHGC values, refer to the Ultraslim Series or Classic Series pages, or contact the team for specification sheets.

Does Window Force ship custom windows across Canada?

Yes. Windows are manufactured at the Concord, Ontario production facility and supplied to builders, dealers, and project sites across Canada. For projects outside Ontario, buyers work through the regional dealer and freight network. Regional contact information is listed on the provincial pages.

What warranty covers Window Force custom windows?

Window Force provides a 25-year transferable warranty. Coverage runs in three tiers: full 100% manufacturer coverage for years 1-25, 80% manufacturer coverage (20% customer responsibility) for years 25-30, and 25% manufacturer coverage (75% customer responsibility) after 30 years. The insulated glass unit carries a separate 10-year non-prorated sub-warranty. The warranty transfers to subsequent owners when the property is sold.
