What GS Services LLC does

GS Services LLC is a family-owned home improvement contractor founded in 2004 and domiciled in Wisconsin, operating under legal name GS Services LLC (previously Gorlewski Specialized Services LLC). The company serves residential homeowners in southeast Wisconsin through three service lines: General Contracting (project management, subcontractor coordination, permit handling, timeline and budget oversight), Complete Remodeling (kitchen, bathroom, basement, and interior reconfigurations), and Outdoor Living Spaces (custom decks, patios, pergolas, outdoor kitchens, and multi-level decking). Execution relies on standard construction techniques combined with premium materials sourced from named brand partners including TimberTech (Advanced PVC composite decking), AZEK Exteriors (PVC trim and post wraps), Westbury (aluminum railings; GS Services holds Certified Master Pro installer status), Owens Corning (GLAS-POWERED composite lumber framing), Trex, Kohler, Moen, and RP Lumber.

The business operates on a sales-led, consultative go-to-market model. Customers reach out through website estimate request forms or phone, after which John Gorlewski conducts an on-site consultation, takes measurements, and issues detailed written quotes with 30-day validity; clients may source materials themselves or through company suppliers. Revenue is generated exclusively through one-time project-based contracts, with no recurring or subscription components. Marketing channels are organic and reputation-driven: company website and blog, email newsletter, project gallery, client testimonials, and BBB Accredited Business status (A+ rating). The company has no disclosed parent, subsidiaries, institutional investors, or funding rounds, and operates as an independently controlled single-entity LLC.

Others

• Trex Company: Leading composite decking manufacturer and competitor/alternative to TimberTech. Adjacent to GS Services through the decking material value chain; relevant for understanding supplier-side dynamics in GS Services' outdoor living service line.
• TimberTech: Composite decking and railing manufacturer listed as a brand partner of GS Services. Adjacent supplier rather than a competitor, but represents the material ecosystem GS Services operates within for outdoor living projects.

Broad incumbents

Comparable as a residential remodeling services provider, though operating at vastly greater scale with a different lead-generation and sales model than GS Services.

Emerging players

• Bath Fitter: National acrylic bathtub and shower liner franchise. Overlaps with GS Services' bathroom remodeling offering but specializes in a narrower product category and franchise delivery model.
• Mr. Handyman: National home repair, maintenance, and remodeling franchise with locations across the Midwest. Comparable to GS Services on residential service delivery, though operating under a franchise model with broader service breadth.
• Re-Bath: National bathroom remodeling franchise network offering full-service bath remodels. Comparable to GS Services' bathroom remodel service line, though delivered through a franchise model rather than local owner-operator.

Direct peers
