A car wash remodel is cars per day and membership attach rate, not a new logo. Vacuum islands that work, LED that sells the wash at night, and a membership kiosk that actually scans plates are mixed invoices. The tunnel conveyor has a serial number. The concrete apron does not.
Car wash renovation and buildout financing is an unsecured term loan from $50,000–$500,000 for that site work. Terms are 3, 5, or 7 years, often funded in 3–10 business days, with no lien on the property. Pricing is quoted per file in an approximate 6%–18% band.
Tunnel gear stays on equipment financing at 6%–14%. Buying the site or the business still starts on car wash and gas station financing at 8.99%–13.5% bridge when the deal is on the deed.
Jaken Finance Group originates property bridge on qualified car-wash files. Site remodel and express conversion pre-qualify on a separate unsecured application.
What the money is for in a car wash remodel
- Vacuum islands, lighting, and signage that lift ticket and membership conversion
- Membership kiosks, LPR, and app-pay when coin and legacy POS are the bottleneck
- Plumbing, electrical, and concrete the landlord or prior operator deferred
- Express conversion finishes — canopies, queue lanes, attendant booth — mixed on one GC bid
- Environmental cleanup shortfalls that still need a documented use of funds — not a substitute for Phase II on a purchase
If the invoice is a new tunnel line from one vendor, start on equipment. If the invoice is site, vacuum, and lighting, stay here. County opening permits and a spring grand reopening rarely wait on a 45–90 day SBA close — that timing gap is what this unsecured note is for.
Model extra cars per day against the note
Default load: a $128,000 site-and-lighting bid, 35 extra cars per day, $6 net per car after chemicals and labor, $5,200 current weekly net, and 2 weeks with the tunnel offline. A 5-year note at an illustrative 12.5% is about $2,878 a month. Use trailing T-12 cars/day, not the first sunny weekend after reopening.
Car wash remodel vs the payment
Test whether extra daily volume after tunnel lighting, membership kiosks, and vacuum islands covers the note after chemicals and attendants. Tunnel equipment with a vendor invoice stays on equipment paper. Estimates only. Pricing is quoted per file.

Unsecured vs equipment vs bridge vs intro 0%
| Need | Better first call |
|---|---|
| Site, vacuum islands, lighting, mixed GC | This page |
| New site, thin revenue, wants the 0% window | Intro 0% business financing |
| Tunnel, arches, pay stations with a vendor invoice | Equipment financing, 6%–14% |
| Buy the wash or the real estate | Car wash and gas station financing |
| Gas pumps and UST environmental | SBA gas station loans when you can wait |
Do not mash unsecured 6%–18% with bridge 8.99%–13.5% or equipment 6%–14%.
Worked example: membership kiosk and LED
An in-bay automatic has a $124,000 bid for LED, vacuum rebuild, and a membership lane. The core wash equipment is fine.
A $124,000 5-year note at an illustrative 12.5% is about $2,788 a month. If membership attach lifts 40 cars a day at $6 net, the note is a timing tool. If volume is already declining, LED will not reverse it.
Worked example: do not hide the tunnel in the GC bid
A $210,000 tunnel package with serial numbers is equipment or part of a car wash bridge file — not this unsecured remodel note. Split it.
What underwriting still wants
- Two years of personal tax returns and wash P&L if available
- FICO 8 — no published minimum
- Lease or deed — this note does not replace property debt
- GC bid with tunnel equipment pulled out
- Trailing cars/day or membership MRR that supports the payment
How to apply
- Split tunnel gear (equipment / bridge) from site work (this page).
- Run the buildout amount in the calculator on 5 years, then stress 3 and 7.
- Submit the unsecured financing form. Thin revenue: use the intro 0% button at the top of this page.
- Buying the site? Start from car wash and gas station financing.

Quick answer: car wash renovation financing
Car wash renovation financing is an unsecured term loan from $50,000–$500,000 for site work, vacuum islands, lighting, signage, tunnel enclosure, and plumbing on a wash you operate. Terms are 3, 5, or 7 years, often funded in 3–10 business days, with no lien on the real estate. Pricing is quoted per file in an approximate 6%–18% band.
Tunnel conveyors, pay stations, and chemical panels with serial numbers stay on equipment financing at 6%–14%. See also car wash and gas station financing for property-level bridge.
Typical car wash buildout and refresh costs
| Scope | Typical range | Product |
|---|---|---|
| Site / concrete / drainage | $30,000–$80,000 | This page |
| Vacuum canopies and plumbing | $18,000–$45,000 | This page |
| Tunnel enclosure and lighting | $35,000–$95,000 | This page |
| Signage and pay lanes | $12,000–$35,000 | This page |
| Tunnel equipment (vendor) | Separate | Equipment |
An express tunnel facade and vacuum lane refresh often lands $95,000–$180,000 before conveyor gear is split out.
Membership, fleet, and cars per day
Membership recurring revenue helps the lift story if churn is stable. Size the note from net per car after chemicals, water, and labor — not gross tunnel revenue on a sunny Saturday.
County opening permits and a spring grand reopening rarely wait on 45–90 day SBA — that timing gap is why operators use this unsecured layer first.
Mistakes that stall car wash remodel files
- New tunnel line on the unsecured bid — equipment paper.
- Lift model uses peak summer only in a four-season market.
- Environmental / water reclamation costs missing from scope.
- Use this note to buy the land — wrong product; see car wash financing.
- Blend bridge 8.99%–13.5% with unsecured 6%–18% in one rate cell.
- Weeks with tunnel offline not in the cash-flow plan.
Documents to gather before you apply
- Two years personal tax returns and wash P&L if available
- T-12 cars per day or membership reports
- GC bid with equipment vendor quotes split out
- Water reclamation / permit docs if municipal
- Lease or deed for the site
- Use-of-funds listing vacuum vs tunnel vs site work
Payment stress test on $128,000 site-and-lighting work
At 12.5% over 5 years: about $2,878 monthly. 35 extra cars per day at $6 net must cover the installment after chemicals and labor — haircut for weather weeks.

Scenario: vacuum island and LED before membership push
An express tunnel does 1,100 cars a week; membership is 22% of revenue. Scope: vacuum canopies, LED tunnel wrap, pay-lane signage — $128,000, no new conveyor.
Owner models 35 extra cars a day at $6 net after chems and labor, 2 weeks at 60% volume during canopy work. 5-year $128,000 at 12.5% ≈ $2,878 monthly.
Water reclamation permit renewal is attached. Tunnel gear stays in place — if the vendor tries to bundle a $400k conveyor, split it off before apply.
Glossary: car wash renovation financing terms
- Site work: Concrete, drainage, and vacuum plumbing — unsecured when no serial numbers.
- Tunnel enclosure: Structure and lighting around existing conveyor — not the conveyor itself.
- Net per car: Revenue minus chemicals, water, and labor — use in the lift model, not gross tunnel sales.
- Membership mix: Recurring plans help the story if churn is stable — show processor reports.
- Property bridge: Buying the land or building — car wash financing, not this note.
Timeline: bid to funded for a car wash site refresh
Week 1: Split tunnel vendor packages from site-and-vacuum GC bid. Week 2: Submit with T-12 car counts and membership report. Week 2–3: Underwriting on net-per-car math. Week 3–4: Fund before seasonal push; phase canopy work in weather windows. Reclamation permit renewals should be cleared before draw if municipal inspection is required.
Why finance the site refresh instead of waiting on tunnel cash
Membership pushes need a clean vacuum lane and lighting before you sell annual plans — members notice canopies, not slogans. Draining $128,000 from distributions delays the membership campaign a full season. If extra cars and memberships clear the 5-year payment after chems and labor, the note buys the season. If volume is capped by location, not presentation, fix pricing and routing first.
