What STS Construction Services does

STS Construction Services is a privately held, full-service general contractor founded in 2000 and headquartered in the Seattle, Washington area, with operations spanning the Seattle and Los Angeles metropolitan markets. The company delivers residential remodeling, custom home building, commercial tenant improvements, condominium renovations, multifamily ground-up development, mitigation and restoration, and waterproofing services, supported by in-house electrical and plumbing trade teams. Notable project deliveries include the 74-unit Keystone Apartments mixed-use development in West Seattle, the 115-unit Harbor Flats development near Alki Beach, and a portfolio of commercial buildouts for clients such as Compass, Oiselle, Hotworx, and Lake Washington Physical Therapy.

The business operates a project-bidding revenue model in which contracts are awarded through proposals, referrals, and inbound 'Get a Bid' inquiries via the company website and phone line. Customer segments span residential homeowners, commercial enterprises (healthcare, fitness, apparel, real estate), multifamily developers and housing organizations (notably Housing Diversity Corp), and condominium associations. Pricing is custom-quoted per project based on scope, materials, and timeline; no public pricing or subscription tiers are disclosed. The firm's go-to-market relies on a sales-led motion anchored by an SEO/portfolio-driven website, Google Reviews social proof, and regional award visibility through the 'Best in the PNW' voting program, with no branded mobile app, API product, or proprietary software platform.

STS participates in co-development partnerships for multifamily housing, working alongside Housing Diversity Corp as co-sponsor and Atelier Drome as architect on flagship projects. The company is independently owned with no disclosed private equity, venture capital, or parent holding company, and maintains a leadership team led by President Craig Haveson alongside CFO Dennis Calkins and CTO Jacob Haney. The firm celebrates 25 years of operation in 2025 and has accumulated five concurrent PNW Best award nominations across customer service and trade categories, signaling brand strength in its core Pacific Northwest market.
