Waterproofing Company EBITDA Valuation Multiples
What buyers are paying for waterproofing businesses in 2024 — and what drives your multiple up or down.
Waterproofing companies in the $1M–$5M revenue range typically sell for 3x–5.5x EBITDA. Buyers pay premiums for recurring maintenance contracts, diversified residential and commercial revenue, and crews that operate without owner involvement. Warranty liability, owner dependency, and inconsistent financials remain the top valuation suppressors in this fragmented, high-demand industry.
Waterproofing Company EBITDA Multiple Ranges by Tier
| Business Tier | EBITDA Range | Multiple Range | Notes |
|---|---|---|---|
| Entry-Level | $150K–$300K | 3.0x–3.75x | High owner dependency, inconsistent revenue, limited recurring contracts, aging equipment, or significant warranty backlog concerns. |
| Mid-Market | $300K–$500K | 3.75x–4.5x | Stable revenue mix, some recurring service agreements, licensed crew in place, clean books with modest add-backs. |
| Strong Performer | $500K–$750K | 4.5x–5.0x | Documented maintenance contracts, diversified client base, operational management layer, and consistent EBITDA growth over 3 years. |
| Premium Asset | $750K+ | 5.0x–5.5x | Scalable systems, branded waterproofing process, strong Google presence, recurring revenue exceeding 20% of total, and minimal owner dependency. |
What Drives Waterproofing Company Multiples
Recurring Revenue Contracts
Positive impactAnnual sump pump inspections, maintenance agreements, and drainage service contracts directly increase multiples by reducing reliance on one-time project revenue.
Warranty Liability Exposure
Negative impactUndisclosed warranty backlogs or high historical callback rates are the fastest way to reduce valuation or kill deals entirely during due diligence.
Owner Dependency
Negative impactIf the owner handles estimating, sales, and client relationships personally, buyers discount heavily due to transition risk and revenue continuity concerns.
Revenue Mix Diversification
Positive impactA healthy split between residential, commercial, and municipal contracts — with no single customer exceeding 15% of revenue — supports higher multiples.
Equipment and Fleet Condition
Positive impactWell-maintained injection rigs, vehicles, and drainage tools reduce buyer capex risk and support full-price offers, especially in SBA-financed transactions.
Recent Market Trends
PE-backed home services roll-up platforms are actively acquiring waterproofing contractors, compressing deal timelines and pushing multiples toward the higher end of the range for clean assets. SBA 7(a) financing remains the dominant deal structure for owner-operator buyers. Warranty liability management and recurring revenue documentation are now table-stakes diligence items that directly influence final pricing and deal structure.

Frequently Asked Questions
What EBITDA multiple should I expect when selling my waterproofing company?
Most waterproofing businesses sell between 3x–5.5x EBITDA. Recurring contracts, clean financials, and reduced owner dependency push multiples toward the higher end of that range.
How does warranty liability affect the sale price of a waterproofing business?
Buyers scrutinize warranty backlog carefully. Large undisclosed obligations or high callback rates often trigger price reductions, earnouts, or escrow holdbacks to offset post-close liability risk.
Can I use an SBA loan to buy a waterproofing company?
Yes. Waterproofing businesses are SBA-eligible. Most SBA 7(a) deals involve 80–90% bank financing, 10% buyer equity, and sometimes a 10% seller note to bridge any financing gap.
What makes a waterproofing company more attractive to PE roll-up buyers?
Roll-up platforms prioritize recurring revenue, scalable operations, licensed technicians, and strong local SEO. Branded systems and documented SOPs significantly accelerate deal interest and valuation.
