Southwest Exteriors

What Southwest Exteriors does

Southwest Exteriors is a privately held, San Antonio-based home exterior remodeling contractor founded in 1989 that serves residential homeowners across the San Antonio metropolitan area and the Texas Hill Country. The company designs, sells, and installs replacement windows, siding (primarily James Hardie fiber cement plus vinyl), entry and patio doors, exterior painting, and ancillary construction and remodeling services. It positions as a quality-focused provider, explicitly accepting that it may not be the lowest-cost option and self-selecting against house-flippers and short-term sellers. Core technology is the physical installation craft and process discipline rather than a software platform; the company cites industrial-grade preparation (e.g., 600-pound diamond grinders for concrete coating) and standardized multi-step paint systems using Sherwin-Williams Duration.

The company offers a multi-brand product portfolio rather than a single OEM relationship. Windows span premium (Marvin Essential, Elevate, and Signature collections), mid-market (ProVia Aeris/Endure/ecoLite, Anlin Del Mar/Coronado), and Texas-made value tiers (Vistamark with Cardinal glass, Don Young). Siding centers on James Hardie HardiePlank lap siding with ColorPlus Technology, supplemented by vinyl. Door products come from Marvin (fiberglass sliding patio), ProVia (fiberglass front/entry and sliding with Amish-grade craftsmanship), and Anlin (vinyl composite). A distinctive proprietary offering is the "Best by Southwest" (BxSW) transferable extended warranty bundling lifetime labor coverage on manufacturer defects, 10 years of foundation/settling adjustments, 10 years of complimentary re-caulking, and accidental glass breakage.

Go-to-market is direct-to-consumer and two-channel: (1) field sales via no-pressure in-home consultations with design consultants who provide quotes valid for 30 days, often with same-day or weekend availability; and (2) inside sales via phone (210-625-7865) and web contact forms, with stated same-day response discipline. Pricing is unit-based and varies materially by project scope and brand selected (e.g., windows from $1,100-$2,800 per opening; siding ~$2,456 per 100 sq ft and $27K-$45K for 1,500 sq ft; single hinged doors $4,189-$9,900). Revenue is one-time project revenue with optional customer financing (0% APR short-term, 2.99% fixed long-term, up to $100,000). The company employs 11-50 people, is BBB-accredited, holds James Hardie Preferred Remodeler and Alliance Elite Contractor status, and has received the yourSA Readers' Choice 2026 award and GuildQuality GuildMaster recognition. No venture, private equity, or strategic ownership is disclosed.
