Castle Impact Windows

What Castle Impact Windows does

Castle Impact Windows Doors & Shutters is a family-owned South Florida hurricane protection installer headquartered in Riviera Beach, Florida. Originally founded in 1969 as Folding Shutter Corporation, the company has rebranded to a multi-product provider serving Palm Beach, Broward, and Martin counties with a claimed installed base of more than 100,000 units over its history and a 4.6-star Google rating.

The company's core offering spans impact windows, impact doors, impact shutters (accordion, roll-down, bahama, colonial), condo shutters, and shutter repair and motor-replacement services. It operates in-house shutter manufacturing in addition to licensed installation crews, and supplements its own shutter line with impact window and door products sourced through distribution partnerships with PGT Innovations, ES Windows, and CGI. A Hurricane Protection Grants advisory service helps homeowners identify and apply for state and federal mitigation funding, feeding installation demand.

The business model is project-based residential and multi-family contracting: homeowners and condo boards purchase installed hurricane envelope solutions priced per opening, with no disclosed subscription or recurring SaaS component. The company runs an in-house Castle Cares 0% interest financing program and current promotional discounts (15% off hurricane solutions) to lower purchase friction. Operating with approximately 6 employees, Castle is a small, privately held local operator rather than a scaled regional platform.

Revenue model

1. Impact Window and Door Sales & Installation: Revenue is generated through the sale and professional installation of impact-rated windows and doors sourced from brand partners (PGT, ES Windows, CGI). Each installation project is custom-quoted based on property size, opening count, product selection, and labor requirements. Projects are sold as one-time purchases with in-house financing options available through Castle's financing program.
2. Hurricane Shutter Sales, Manufacturing & Installation: Shutters (accordion, roll-down, Bahama, colonial, storm panels) are manufactured in-house and sold with professional installation. Shutters can also be sold as standalone products for properties that only need exterior storm protection. This stream benefits from in-house manufacturing control, reducing dependency on third-party suppliers and enabling faster delivery timelines for the shutter portion of projects.
3. Shutter Repair Services: Post-installation revenue is generated through shutter repair services for stuck, bent, misaligned, or damaged existing systems. Repair services address aging or malfunctioning shutters across the company's installed base, providing recurring service revenue and strengthening customer retention.
4. In-House Financing (Castle Cares): Castle offers in-house monthly financing with 0% interest promotional payments, enabling customers to afford higher-ticket installations through installment payments rather than full upfront payment. This financing product drives conversion for higher-value multi-opening projects.
