A picks-and-shovels position on a consolidating, automation-heavy, mechanically exposed market — equipment installation, control-wiring, and recurring service for car wash operators nationwide.
The U.S. car wash sector is large, fragmented, capital-intensive, and mid-way through a structural shift from owner-operators to private-equity-backed multi-site platforms. That combination is what makes the equipment-install, control-wiring, and service trade — not the wash operation itself — an attractive place to stand.
The modern express tunnel is no longer a building with brushes; it is a synchronized machine: conveyor, tunnel controller, pay stations, membership recognition, chemical dosing, water reclaim, RO/spot-free, vacuums, blowers, safety interlocks, and remote reporting. Every new build, conversion, and acquisition needs that system set, plumbed, wired, and integrated — and every operating tunnel needs recurring preventive maintenance to protect the membership revenue that now underpins valuations.
Operators carry the real-estate, traffic, and debt risk. An independent, brand-agnostic, nationwide install-and-controls crew sells into the capex cycle, the retrofit cycle, and the recurring uptime cycle — winning on coverage, speed-to-uptime, OEM neutrality, and price against a service landscape dominated by the equipment makers themselves.
Published estimates vary by definition; the engine underneath a flat headline is express-exterior and subscription, both growing far faster than the overall market.
Authoritative site counts come from the International Carwash Association's commissioned census. The installed base splits across three operating formats:
Equipment & install share of spend. A new express tunnel is a $3–7M+ project. Wash equipment alone runs $1.4–2.1M, with electronics, pay stations, and tunnel controls at $150–400K and water treatment at $50–250K. The U.S. equipment market is put at ~$1.8B (2024), growing to ~$2.6B by 2031 at ~5% CAGR. Installation, control-wiring, and commissioning labor — the layer Car Wash Protocol monetizes — is not separately reported publicly; it is modeled below.
High-throughput tunnels (100+ cars/hr) now lead new construction and are the most controls-heavy format.
Of wash sales at the largest operator come from memberships — making uptime mission-critical and downtime expensive.
Institutional ownership of the express segment by site count, 2019→2025. Multi-site owners want one accountable vendor.
Functional obsolescence cycle; belts replaced every 4–5 years. Recurring, non-discretionary maintenance.
Of payments are cashless and rising — driving LPR, RFID, POS, and tunnel-controller turnovers industry-wide.
Water recovered per wash; increasingly mandated or cost-driven, each retrofit is plumbing + controls work.
In-bay-to-express conversions rebuild a site's throughput — a full install & controls job, not a tune-up.
The operator's business is washing cars; Car Wash Protocol's business is keeping the iron running. Four revenue lines, sized directionally from published per-site and install-base inputs.
| Segment | What it is | Annual U.S. value* |
|---|---|---|
| New-build install & controls | Rigging, plumbing, electrical, controls integration, commissioning on new tunnels & conversions | $0.8–1.5B |
| Recurring maintenance | Scheduled PM, parts, and break-fix across the operating tunnel + in-bay base | $1.0–2.0B |
| Controls & POS retrofits | PLC upgrades, kiosks, LPR/RFID, tunnel controllers, water-system integration | $0.25–0.8B |
| Emergency / breakdown | Rapid-response repair where downtime bleeds membership revenue | $0.2–0.4B |
| Combined addressable opportunity | ~$1.5–3B+ | |
Maintenance is counter-cyclical-ish: when rates rise and new builds stall, operators defer capex and nurse existing equipment — shifting the mix toward the highest-margin recurring line rather than shrinking the opportunity. Gross margins on maintenance contracts typically run 40–60%, with low capital intensity.
The OEMs build and service their own ecosystems. Consolidated operators inherit mixed fleets — and want a neutral crew that works across all of them.
| Edge | Why it matters to a multi-site operator |
|---|---|
| Coverage | PE platforms run 20+ states and need one accountable partner, not 20 local contractors. |
| Speed-to-uptime | Membership revenue makes downtime expensive; SLA response beats OEM scheduling backlogs. |
| Neutrality | Services mixed OEM fleets without pushing proprietary parts or software lock-in. |
| Price | No equipment-sales markup on labor — commonly 15–25% under OEM-direct service. |
| Rollout discipline | Standardized installs, labeling, cutovers, and documentation across every site. |
Electricians and controls techs are scarce — the biggest constraint, but also the moat for a crew that trains and retains at scale.
Higher rates slow new builds and M&A (Zips' 2025 Chapter 11 is the cautionary tale) — but recurring service is rate-agnostic.
Saturation in some metros slows greenfield — and raises retrofit, conversion, and distressed-asset service demand.
Proprietary controls and warranties can fence out third parties; mitigated by multi-brand certification and post-warranty focus.
An install-and-controls service company sits at the intersection of secular growth, consolidation, and a continuous technology-upgrade cycle. The base is huge and aging; consolidation creates ideal multi-site customers; the growth is concentrated in the controls-heavy express and subscription segments; and the recurring maintenance core holds up even when new construction slows.
The best version of Car Wash Protocol is not a handyman crew and not a commodity electrical sub. It is a national, brand-agnostic car wash infrastructure company — recurring maintenance revenue, retrofit revenue, emergency-response pricing power, and exposure to both the installed base and future express development. Built for operators. Designed to scale.
*Dollar figures for the install + controls + service layer are directional estimates modeled from published per-site economics, equipment-market sizing, and installed-base counts — no single published study isolates this sub-segment at this granularity. They are order-of-magnitude scoping for investor discussion, not audited figures. Headline market-size estimates vary materially by source definition (services-only vs. services + detailing vs. per-site census); ranges are shown where sources diverge.
