DSI

What DSI does

DSI (Door Sales & Installations) is a Tempe, Arizona-based specialty subcontractor that supplies and installs complete residential door and trim packages for production homebuilders. The company sources, kits, delivers, and professionally installs six core product categories for each home: fiberglass exterior doors, interior doors, architectural trim and millwork, builder hardware, custom shutters, and shelving. Serving 24 home builders across the Phoenix and Tucson metros, DSI packages roughly 7,000 homes per year and positions itself as a single-source alternative to multi-vendor procurement. Operations are supported by in-house pre-assembly, dedicated delivery logistics, and trained installation crews, with the company claiming industry-leading manufacturing efficiency and waste minimization.

The business model is B2B and sales-led, with direct field sales to enterprise residential builders, hands-on jobsite delivery, and installation wrapped into a single package delivered on schedule. DSI does not appear to monetize software, licensing, or aftermarket services; revenue is effectively one-time product-plus-installation fees tied to the new-construction cycle of its builder customers. The core technology stack is operational rather than digital: refined manufacturing workflows, logistics scheduling, and physical installation labor; there is no public API, SDK, or software product, and no disclosed AI, data, or platform capabilities. Pricing is not publicly disclosed.

DSI is structured as DSI LLC, an Arizona LLC, and operates as a division of Erickson Companies, which sits within the Synergos Companies family of integrated residential construction trades (framing, electrical, HVAC, concrete, plumbing, and others). Ownership is private with no disclosed venture, private equity, or public capital; leadership is long-tenured and promotes from trades through operations, and the company has been continuously operating since at least 1980. Its geographic footprint is single-state (Arizona), and its customer footprint is a concentrated roster of 24 builders, making its revenue tightly coupled to Phoenix/Tucson single-family housing starts.

Direct peers

• Metrie: Metrie is a leading North American manufacturer and supplier of interior millwork, doors, and finishing products for residential builders and remodelers. As one of DSI's core strategic suppliers, Metrie overlaps directly in product categories and target customer base.
• Lansing Building Products: Lansing Building Products is a national distributor and installer of exterior building products including doors, windows, trim, and specialty building products serving residential builders. Their combined supply-and-install model directly mirrors DSI's approach, making them the most operationally comparable peer.

Broad incumbents

• SRS Distribution: SRS Distribution is a national building products distributor focused on roofing, siding, windows, doors, and related exterior products for residential and commercial contractors. Their builder-facing supply model overlaps with DSI's distribution channel approach.
• JELD-WEN: JELD-WEN is a leading global manufacturer of windows, doors, and related building products serving residential builders. They compete in DSI's core categories with significant scale advantages and national builder account relationships.
• Builders FirstSource: Builders FirstSource is one of the largest U.S. suppliers of building products, prefabricated components, and value-added services to professional residential builders. They compete with DSI in residential new construction supply at significantly greater scale and product breadth.
• Masonite International: Masonite International is one of the world's largest manufacturers of interior and exterior doors. They operate at scale in DSI's core product category and represent both a potential supplier partner and competitive threat to DSI's installed base.
• ABC Supply Co. ABC Supply is the largest wholesale distributor of roofing, siding, windows, doors, and exterior building products in North America. While primarily a distributor rather than installer, they compete in adjacent building products categories serving similar builder customers.
• Cornerstone Building Brands: Cornerstone Building Brands is a leading manufacturer of exterior building products including siding, windows, and doors serving residential builders. They operate upstream of DSI as a supplier but compete for builder mindshare and product specification.
• BMC Stock Holdings: BMC Stock Holdings is a major U.S. building products supplier serving builders and remodelers with lumber, components, doors, and windows. Their scale, builder relationships, and product breadth make them a broad competitive threat to regional installers like DSI.
