GS Exterior Experts

What GS Exterior Experts does

GS Exterior Experts is a family-owned and operated exterior remodeling contractor headquartered in Littleton, Colorado, with a secondary office in Denver. Founded in 1999, the company sells and installs siding, roofing, windows, and decks for residential and multi-family/commercial customers across the Denver metro and Colorado Front Range (20+ markets). Its core technology is craftsmanship and installation process rather than software: a 25+ year "Gold Standard" installation methodology with owner on-site involvement, plus specialized expertise in Colorado-specific climate conditions including hail, high-altitude UV, freeze-thaw cycles, and wildfire risk (with explicit Colorado Wildfire Resiliency Code compliance). The company carries certified status with a broad set of premium building product manufacturers — James Hardie (where it is Colorado's #1 Elite Preferred Contractor and a four-time President's Club Award winner), LP SmartSide, Owens Corning, GAF, CertainTeed, Andersen, Marvin, Pella, TimberTech, Trex, EverLog, DECRA, Boral, Nichiha, and others — and offers an online estimator and design tools that allow homeowners to obtain instant price ranges prior to a free on-site consultation.

The business model is project-based professional services revenue: each job is quoted and completed with company-employed installation crews, with pricing on a per-square-foot basis (e.g., vinyl $8-$12, fiber cement $14-$18, LP SmartSide $18-$22) and flexible financing available for qualified customers. Three revenue streams are documented: (1) full exterior remodeling installation services (siding, roofing, windows, decks) for residential homeowners, (2) storm restoration services bundled through homeowner insurance claims, often combining multiple trades into a single insurance-funded job, and (3) commercial and multi-family exterior projects for HOAs, apartment complexes, condominiums, and townhome communities. GTM is sales-led and multi-channel: a website with estimator and design tools drives top-of-funnel leads; phone, email, and online contact forms feed inside sales; on-site estimates and insurance-claim navigation convert at the bottom of the funnel; and a referral program generates post-sale leads. Marketing leverages Google Business, Facebook, Instagram, Houzz, LinkedIn, Pinterest, YouTube, and Twitter; awards and reputation (BBB A+, Google 5-star) are heavily emphasized as trust signals. The company is privately held with no disclosed institutional investment, parent entity, or subsidiaries, and no financial details (revenue, headcount, funding) have been publicly disclosed.
