Feldco Windows, Siding and Doors

What Feldco Windows, Siding and Doors does

Feldco Windows, Siding and Doors is a privately held home exterior renovation company headquartered in Rosemont, Illinois, founded in 1976 and operating as Feldco Factory Direct, LLC. The company designs, manufactures, and installs custom-built replacement windows (vinyl, multiple styles), vinyl and LP SmartSide engineered wood siding, fiberglass and steel entry doors, patio doors, storm doors, garage doors, and Owens Corning roofing systems for residential homeowners in the Midwest. Products incorporate energy-efficiency features including LowE glass coatings, DuraLite spacer systems, double-pane insulated glass units, and argon fills, and are custom-fit to exact opening dimensions before installation by Feldco-certified crews.

The company runs a direct-to-consumer, sales-led go-to-market combining 14 retail showrooms across Illinois, Wisconsin, Indiana, Iowa, and Michigan, in-home consultation by Product Specialists, phone sales, and an online quote-request funnel. Pricing is quote-based, supported by aggressive promotional financing (e.g., 50 months no interest, 25% off roofing) routed through third-party lending partners. A $100 referral rewards program and the myFeldco customer portal add a structured post-sale engagement layer. The company claims more than 500,000 homes served, "Midwest's #1 home exterior company" positioning, and 12 consecutive Chicago Tribune Top Workplaces awards.

Feldco has no disclosed funding, no parent company, no public listing, and no acquisition history in the source data. Revenue is not publicly disclosed; the 101-250 employee range and 14-showroom regional footprint are consistent with a $100M-$250M annual revenue band. Product innovation centers on material durability (DuraLite, T3-LOK, SmartGuard) and weather-resilience tuned to Midwest climate extremes, with no meaningful AI, software platform, or API offerings.
