What Custom Window Systems does
Custom Window Systems (CWS), founded in 1986 and headquartered in Ocala, Florida, designs and manufactures impact-resistant and non-impact vinyl and aluminum windows, doors, sunroom enclosures, and garage door screens engineered specifically for Florida's hurricane-prone coastal climate. The company's core technology centers on laminated glass with polymer interlayers tested to ASTM E1996 missile D ratings, multichambered vinyl frames with fusion-welded construction, and corrosion-resistant aluminum assemblies. Its portfolio is structured across five sub-brands—Hurricane Guard (highest-rated impact), StormStrong (vinyl impact and non-impact), Comfort Shield (vinyl non-impact), Fortify (aluminum non-impact), and WeatherLite (sunrooms in glass, acrylic, and soft-vinyl)—each targeting distinct price-performance and application segments within the coastal fenestration market. CWS operates 700,000+ sq. ft. of manufacturing facilities across Ocala, Miami, Medley, and Jacksonville, with Florida Product Approvals and Miami-Dade County NOAs certifying compliance with High Velocity Hurricane Zone requirements.
CWS generates revenue exclusively through sales of finished fenestration products to residential and commercial construction and replacement customers, distributed via an authorized dealer network rather than direct-to-consumer channels. Pricing is set at the dealer level and is not publicly disclosed. The company is privately held and operates as a subsidiary of Pella Corporation, a leading national window and door manufacturer, which provides corporate backing and brand credibility. Dealers are supported with a dedicated portal, marketing resources, technical documentation, and a customer service operation that answers calls within 30 seconds. Geographic reach spans Florida, Georgia, North Carolina, and South Carolina, with products sold for both new construction and replacement projects across residential and commercial segments.

Custom Window Systems competitors and assessment
Company assessmentDirect peers
- WinDoor Inc. Florida-based manufacturer of impact-resistant and non-impact windows and doors serving the same coastal Florida market. Closely comparable in product mix (vinyl and aluminum), certifications, and dealer-channel distribution.
- CGI Windows & Doors: Florida-based manufacturer of impact-resistant and non-impact windows and doors, now owned by MITER Brands. Direct competitor in the Florida coastal impact fenestration segment with overlapping Miami-Dade NOA-certified product lines targeting the same dealers and homeowners.
- Eastern Architectural Systems: Florida-based manufacturer of vinyl and aluminum impact windows and doors, now part of MITER Brands. Direct competitor in Hurricane Guard and StormStrong's core market, competing on similar product specs, certifications, and dealer relationships.
- PGT Innovations (now MITER Brands): Florida-headquartered impact-resistant window and door manufacturer and CWS's most direct competitor. PGT Innovations acquired CGI Windows & Doors and Eastern Architectural Systems, consolidating the Florida impact fenestration segment that overlaps almost entirely with CWS's Hurricane Guard and Fortify lines.
Emerging players
- Therma-Tru Doors: Leading fiberglass and steel door manufacturer (part of Fortune Brands Innovations) with growing impact-rated door offerings. Comparable in door product engineering and Florida-market presence but focused on entry and patio doors rather than CWS's broader fenestration portfolio.
Broad incumbents
- Andersen Windows & Doors: Largest U.S. window and door manufacturer with national distribution and broad product portfolio including impact-rated lines. Overlaps with CWS in coastal replacement markets but competes across the full spectrum of residential and commercial fenestration nationally.
- JELD-WEN: Global manufacturer of windows, doors, and related building products serving residential and light commercial markets. Broadly comparable in fenestration products though JELD-WEN's portfolio extends to interior doors and other categories beyond CWS's scope.
- Marvin Windows and Doors: Premium national manufacturer of windows and doors including impact-rated coastal product lines. Comparable in manufacturing depth and certification programs but positioned more toward the premium and custom architectural end of the market than CWS's volume coastal focus.
- MI Windows and Doors: Large U.S. vinyl and aluminum window manufacturer serving replacement and new construction across multiple regions. Overlaps with CWS in vinyl window manufacturing but at broader national scale and without CWS's hurricane-rated certification concentration.
- Pella Corporation: CWS's parent company and one of the largest national window and door manufacturers. Comparable product categories (vinyl, aluminum, impact-rated windows and doors) but operates nationally across new construction, replacement, and commercial segments well beyond CWS's coastal focus.
