Keldan

What Keldan does

Keldan Ltd. is a privately held, family-style windows and doors sales and installation company headquartered at 17915 Leslie Street, Newmarket, Ontario, operating under Keldan since its founding in 1976. The company serves residential homeowners primarily across York Region, Ontario, with select commercial and heritage-building work (e.g., Newmarket Chamber of Commerce railway station, church installations). Its core offering is vinyl window and door replacement executed via a "Brick-to-Brick" installation methodology — full removal of the existing frame before installing the new unit — paired with a True Lifetime product warranty on most SKUs and a 5–10 year installation warranty.

Keldan's product portfolio is assembled through a multi-supplier channel-partner model: VinylGuard and VinylBilt supply vinyl windows, EntryGuard and MasterGrain supply entry/fiberglass doors, WindSpec supplies commercial-grade products, and VELUX Canada and Everlast Products supply skylights and aluminum products. The company employs full-time permanent installation and sales staff rather than subcontractors, and pairs a physical showroom with in-home measurement and consultation services. A small transactional e-commerce storefront (keldan.ca/shop) carries a limited number of in-stock SKUs.

The business model is direct-to-consumer, project-based, and regional. Revenue is generated from one-time product sales plus installation services priced via quote after on-site measurement. Marketing relies on the company website, Google reviews, BBB accreditation, and customer testimonials rather than paid performance channels. Pricing is not publicly disclosed at the project level, with the only published unit price being a $299.99 VinylGuard Casement window SKU. Geographic reach is confined to York Region, Ontario, and there are no disclosed funding events, acquisitions, or external investment.
