PCI Builders

What PCI Builders does

PCI Builders, operating under the legal entity Plumb Crazy, Inc., is a privately held, woman-owned general contracting firm headquartered in Monrovia, California, serving residential and commercial clients across Southern California. Founded in 2008, the company provides design, remodeling, and new construction services spanning kitchen and bathroom remodels, custom spaces, outdoor living areas, accessory dwelling units (ADUs), home additions, and commercial buildouts including offices, retail spaces, and high-rise tenant improvements. Revenue is earned through project-based, fixed-price general contracting contracts acquired primarily via direct sales, referrals, and an established portfolio of completed work showcased across social media channels (Facebook, Twitter, Pinterest, Instagram, Houzz). Pricing is quoted per-project and not publicly disclosed.

The company's most strategically significant capability is its introduction of 3D Concrete Printing (3DCP) to the Southern California market, using a large computer-controlled robotic printer and a proprietary concrete mix supplied by core technology partner Sika. The technology forms structural walls layer by layer from a digital design, producing non-combustible, seismically rated, and hurricane-rated structures that are described as roughly twice as energy efficient as conventional stick-built construction. PCI Builders received its first 3DCP building permit in February 2026 for a home and detached garage to be printed in Altadena, a community impacted by the January 2025 Eaton Fire, with printing scheduled to begin in June 2026. The firm also offers Sonic Fire Tech, an acoustic fire suppression solution. The product portfolio therefore combines traditional general contracting services with emerging automated construction and fire-resilience technologies, targeting both homeowners and commercial property owners in a regional SoCal market.

Scale indicators1 record

Recent moves5 records

Expansion highlights4 records

Emerging players

• Blu Homes: Blu Homes is a precision-engineered, prefabricated home builder using factory-built steel-framed modules for custom and modern residential designs. It is an emerging player in the same innovative residential construction space, with overlapping tech-forward approach but a different material system.

Others

• Sika AG: Sika is a global specialty chemicals company supplying the proprietary concrete mix used in PCI Builders' 3DCP technology. It is an adjacent ecosystem participant and core technology partner rather than a competitor, but materially shapes PCI's 3DCP offering.
• COBOD International: COBOD is a leading manufacturer of construction-scale 3D concrete printers and supplies gantry-based 3DCP systems globally, including to many U.S. printed-building projects. It is an enabling technology supplier and adjacent ecosystem participant rather than a direct competitor.

Broad incumbents

• DPR Construction: DPR Construction is one of the largest U.S. general contractors, with significant presence in California and a track record of adopting innovative construction methods. It is comparable as a broad incumbent in the same nonresidential building construction category, though at far greater scale and breadth.
• Swinerton: Swinerton is a 135-year-old national general contractor with deep West Coast roots and California headquarters. It is comparable as a broad incumbent serving both commercial and residential construction in the same regional market.

Direct peers

• Mighty Buildings: Mighty Buildings is a 3D-printed home and building startup, originally based in Oakland, California, that uses proprietary materials and robotic printing to produce prefabricated residential structures. It is the most directly comparable peer in both technology (3D printing for buildings) and target market (California residential construction).
• ICON: ICON develops large-scale 3D construction printing technology and has delivered printed homes across the U.S., including community-scale projects. It is a direct technology peer using robotic concrete printing for residential structures, though at much larger scale and with proprietary Vulcan printer systems.
• Plant Prefab: Plant Prefab is a California-based prefabricated and sustainable home builder using factory-built components for custom residential projects. It is comparable as a Southern California builder applying innovative off-site/modular construction methods to the custom home market.

Regional players

• Habitat for Humanity of Greater Los Angeles: Habitat for Humanity Greater LA builds affordable and workforce housing in the Los Angeles region, including post-disaster rebuilding efforts. It is a regional peer in residential construction serving the same SoCal geography and increasingly relevant in fire-rebuild contexts.
• The New Home Company: The New Home Company is a California-focused homebuilder specializing in attached and detached for-sale residential communities. It is a regional peer in California residential construction with a similar geographic concentration, though focused on production homebuilding rather than custom/remodel.
