How to Use an SBA Loan to Buy a Foundation Repair Business
Foundation repair is one of the most SBA-financeable specialty trades in home services — non-discretionary demand, strong margins, and recession-resistant revenue make these deals attractive to lenders. Here's exactly how to structure the financing.
Find SBA-Eligible Foundation Repair BusinessesSBA Overview for Foundation Repair Acquisitions
Foundation repair businesses are strong candidates for SBA 7(a) acquisition financing. Lenders favor the industry for several reasons: demand is non-discretionary and inspection-triggered (homeowners cannot defer structural repairs without risking property value or failing real estate transactions), gross margins on piering, wall stabilization, and crawl space encapsulation typically run 45–60%, and the fragmented market means established regional operators carry durable local brand moats. For buyers targeting a foundation repair company in the $1M–$5M revenue range with $500K+ EBITDA, an SBA 7(a) loan can cover up to 90% of the total project cost — including the business purchase price, working capital, and in some cases real estate — with repayment terms up to 10 years for business acquisitions and 25 years when commercial real estate is included. The typical deal structure pairs an SBA 7(a) loan (80–85% of deal value) with a 10–15% buyer equity injection and an optional seller note of 5–10% placed on 24-month standby, satisfying lender equity requirements while reducing the cash burden on the buyer at close.
Down payment: Most SBA 7(a) lenders require a minimum 10% equity injection for foundation repair acquisitions where the business has clean financials, transferable licenses, low warranty liability, and an EBITDA above $500K. In practice, buyers targeting foundation repair companies should plan for 10–15% down on the total project cost. For a $2.5M acquisition, that means $250,000–$375,000 in equity from the buyer. Lenders may require 15–20% when the deal carries elevated risk factors — such as a high volume of open or unresolved warranty claims, significant owner-dependence on referral relationships, or revenue concentration in fewer than five referral sources. A seller note of 5–10% of the deal value, placed on 24-month standby, is frequently used to bridge the gap between the SBA loan and the purchase price while meeting lender equity requirements — but the seller note must be formally subordinated and the lender must approve it as part of the capital stack before closing.
SBA Loan Options
SBA 7(a) Standard Loan
10-year repayment for business acquisition; 25 years if commercial real estate is included; variable rate typically Prime + 2.75% or fixed equivalent
$5,000,000
Best for: Full business acquisitions of foundation repair companies where the buyer is acquiring goodwill, equipment, trained crews, and customer relationships — the most common structure for deals in the $1M–$4M purchase price range
SBA 7(a) Small Loan
10-year repayment; streamlined underwriting with faster approval timelines; variable rate at Prime + 3.25%
$500,000
Best for: Smaller foundation repair acquisitions or add-on acquisitions where the deal value is under $500K — useful for buyers adding a second territory or acquiring a retiring owner-operator's book of business with minimal hard assets
SBA 504 Loan
10- or 20-year fixed rate on the CDC portion; requires 10% buyer equity injection, 40% CDC debenture, 50% bank first mortgage
$5,500,000 (combined CDC and bank portions)
Best for: Foundation repair acquisitions that include the purchase of an owner-occupied commercial facility — shop, warehouse, or equipment yard — where real estate constitutes a significant portion of deal value and the buyer wants long-term fixed-rate financing on the property component
Eligibility Requirements
- The foundation repair business must be a for-profit U.S.-based company operating as a sole proprietorship, LLC, S-corp, or C-corp and must meet SBA size standards — typically under $8M in average annual receipts for specialty trade contractors under NAICS 238990
- The buyer must inject a minimum of 10% of the total project cost from personal, non-borrowed funds; for acquisitions with higher intangible value or warranty liability exposure, some lenders will require 15–20% equity injection
- The business must show at least 3 years of tax returns with consistent or growing revenue and sufficient EBITDA to service the proposed debt — most SBA lenders require a minimum 1.25x debt service coverage ratio (DSCR) after buyer compensation
- Neither the buyer nor the seller can have active federal tax liens, unresolved SBA defaults, or pending litigation that materially impairs the business's ability to operate — warranty-related lawsuits must be disclosed and evaluated during underwriting
- The acquisition must be for a legitimate change of ownership; partial acquisitions of less than 51% of equity are generally ineligible, and any seller equity rollover must be subordinated to the SBA loan with lender approval
- All required contractor licenses, bonding, and insurance policies — including general liability and workers' compensation covering foundation crew operations — must be transferable or re-issuable to the buyer entity as a condition of loan closing
Step-by-Step Process
Establish Your Acquisition Criteria and Financial Profile
Before approaching lenders, define your target parameters for a foundation repair acquisition: minimum $500K EBITDA, established regional brand, trained crew with low turnover, and clean warranty and licensing records. Simultaneously, prepare your personal financial statement, 3 years of personal tax returns, a personal credit report (lenders target 680+ FICO for SBA approval), and a resume demonstrating relevant experience in construction, home services, or business operations. Lenders financing specialty trade acquisitions want to see that the buyer understands the operational realities of running a crew-based foundation repair business.
Identify an SBA-Preferred Lender with Home Services Experience
Not all SBA lenders understand the nuances of foundation repair acquisitions — specifically warranty reserve liabilities, crew certification requirements, and job costing structures. Seek out SBA Preferred Lender Program (PLP) banks or non-bank SBA lenders (such as Live Oak Bank, Newtek, or regional community banks with active home services lending practices) that have closed specialty trade deals. A lender familiar with NAICS 238990 trades will be better equipped to evaluate the business's goodwill value, understand the warranty liability schedule, and structure a loan that accounts for post-close working capital needs.
Submit Letter of Intent and Order Quality of Earnings Report
Once you identify a target foundation repair business, submit a non-binding LOI at a purchase price reflective of 3.5–5.5x EBITDA depending on crew quality, warranty record, and referral network depth. Simultaneously, engage a CPA or financial advisor to conduct a Quality of Earnings (QoE) analysis — this is increasingly required by SBA lenders on acquisitions above $1.5M. The QoE will normalize EBITDA by adding back owner compensation above market rate, personal vehicle expenses, and one-time costs, while flagging any warranty reserves that should be deducted from adjusted EBITDA. This document becomes the centerpiece of your lender package.
Submit SBA Loan Application with Complete Lender Package
Your lender package for a foundation repair acquisition should include: 3 years of business tax returns and CPA-prepared financials, year-to-date P&L and balance sheet, Quality of Earnings report, a detailed warranty obligations schedule with historical claim rates by repair type (piering, wall stabilization, waterproofing), crew roster with certifications and tenure, all active contractor licenses and insurance certificates, a customer and referral source concentration analysis, and a signed purchase agreement or LOI. Provide a written business plan outlining your 3-year growth strategy, including how you plan to maintain existing referral relationships with realtors and home inspectors post-close.
Lender Underwriting and SBA Authorization
During underwriting, the lender's credit team will stress-test the business's debt service coverage using adjusted EBITDA minus a market-rate management salary for you as the new owner-operator. For foundation repair businesses, underwriters will scrutinize warranty reserves carefully — expect the lender to apply a haircut to EBITDA if open warranty claims are significant or if historical call-back rates suggest above-average defect exposure. The lender will submit the approved loan to the SBA for authorization, which adds 2–4 weeks for standard 7(a) loans or can be faster under SBA Express or delegated authority programs used by PLP lenders.
Due Diligence, Environmental Review, and Pre-Close Conditions
Concurrent with underwriting, complete full legal and operational due diligence on the foundation repair business. Key focus areas: review all outstanding warranty claims and indemnification obligations; verify all crew certifications (Supportworks, Basement Systems, or equivalent franchisor-licensed systems); confirm contractor licenses are current and transferable; order Phase I environmental review if real estate is included; and audit job costing records to validate gross margins by service line. Address any pre-close lender conditions — which may include evidence of key-person life insurance on the seller during the transition, assignment of referral agreements, or escrow holdbacks for open warranty claims.
Close, Fund, and Execute Transition Plan
At closing, the SBA loan proceeds fund the seller's purchase price, with the buyer's equity injection and any seller note proceeds applied per the agreed capital stack. Immediately post-close, execute a structured 30–60–90 day transition plan focused on three priorities specific to foundation repair businesses: (1) introduce yourself to the top 10 referral sources including key realtors, home inspectors, and insurance adjusters; (2) meet individually with each crew member and lead technician to assess retention risk and communicate your operational vision; (3) audit all open warranty files and establish a formal warranty management process so no claims fall through the cracks and create liability exposure in your first year of ownership.
Common Mistakes
- ✗Underestimating warranty reserve liability during due diligence — many foundation repair acquisitions carry multi-year or lifetime warranty obligations that never appear on the balance sheet. Buyers who fail to model historical call-back rates by repair type often discover in year one that warranty fulfillment costs are eroding the EBITDA margin they underwrote. Require the seller to provide a full warranty obligation schedule and build a reserve into your post-close working capital plan.
- ✗Failing to account for owner-dependent revenue in the SBA loan's DSCR calculation — if the seller is personally responsible for referral relationships with the top five realtors or a major insurance adjuster network, that revenue is at risk post-close. Lenders and buyers both make the mistake of treating historical revenue as fully transferable without validating how much is relationship-dependent. Structure an earnout or seller transition period to protect this revenue stream.
- ✗Approaching generic SBA lenders unfamiliar with specialty trade acquisitions — a lender without home services experience will struggle to underwrite crew-based EBITDA, evaluate warranty liability schedules, or value proprietary repair systems like helical pier programs. This leads to longer timelines, unnecessary documentation requests, and in some cases, declined loans that a home services-experienced SBA lender would have approved.
- ✗Neglecting to verify contractor license transferability before submitting the SBA loan application — foundation repair businesses operate under state and county contractor licenses that may not automatically transfer to a new legal entity. If the license is held personally by the seller and cannot be reassigned, the buyer faces a gap period during which the business technically cannot operate legally. Identify this early and factor license re-application timelines into the deal structure and closing conditions.
- ✗Using all available working capital for the equity injection, leaving no liquidity for post-close operations — foundation repair businesses have seasonal revenue patterns and may carry significant payroll for field crews between project cycles. Buyers who inject every available dollar to meet the 10% SBA equity requirement and close the deal often find themselves cash-constrained within 90 days. Request that the SBA loan include a working capital line or negotiate a seller note structure that preserves buyer liquidity post-close.
Lender Tips
- Seek SBA Preferred Lender Program (PLP) lenders with a documented track record in home services or specialty trade acquisitions — they can issue SBA authorization under delegated authority, cutting 2–4 weeks off your timeline compared to standard channel lenders. Ask any prospective lender directly how many foundation repair or specialty trade deals they have closed in the past 24 months.
- Present a clean warranty obligations package upfront — lenders will discover open warranty claims during underwriting regardless, so proactively preparing a warranty schedule with historical call-back rates, reserve methodology, and outstanding claim exposure signals that you understand the business and reduces lender skepticism about post-close liabilities.
- Structure the seller note correctly from the start — SBA guidelines require seller notes to be on full standby for at least 24 months post-close, meaning no principal or interest payments can be made to the seller during that period. Some buyers and sellers negotiate seller notes without understanding this requirement, which can derail the loan at the commitment stage. Confirm your lender's specific seller note standby requirements before finalizing deal terms.
- Demonstrate operational competence in your business plan — SBA lenders financing specialty trade acquisitions want evidence that the buyer can actually run a crew-based business. Highlight any prior construction management, home services operations, or field supervision experience prominently. If you lack hands-on trade experience, consider committing to a 60–90 day operational transition period with the seller as part of the deal structure to reduce lender concern about management continuity.
- Order the Quality of Earnings report before submitting the full lender package — attempting to submit an SBA loan application for a foundation repair acquisition above $1.5M without a QoE report will slow underwriting significantly as the lender's credit team rebuilds the EBITDA normalization themselves. A QoE completed by a reputable CPA accelerates lender review, reduces back-and-forth information requests, and often results in a higher adjusted EBITDA figure that supports a better loan-to-value ratio.

Frequently Asked Questions
Can you use an SBA loan to buy a foundation repair business?
Yes. Foundation repair businesses are highly SBA-eligible under NAICS code 238990 (specialty trade contractors). They generate strong EBITDA margins, have non-discretionary demand, and typically meet the SBA's size standard of under $8M in average annual receipts. SBA 7(a) loans are the most common financing tool for foundation repair acquisitions in the $1M–$5M revenue range, covering up to 90% of the total project cost.
How much money do I need to put down to buy a foundation repair business with an SBA loan?
The SBA requires a minimum 10% equity injection from the buyer's personal funds — not borrowed money. For a $2.5M foundation repair acquisition, that means at least $250,000 out of pocket. Lenders may require 15–20% if the deal carries elevated risk factors such as significant warranty liability exposure, heavy owner-dependence, or revenue concentration in a few referral sources. A seller note of 5–10%, placed on 24-month standby, is commonly used to reduce the buyer's cash requirement at close.
How does SBA underwriting handle warranty liabilities in a foundation repair acquisition?
Warranty liabilities are one of the most scrutinized elements in foundation repair SBA underwriting. Lenders will require a complete schedule of open warranty claims, historical call-back rates by repair type, and an assessment of the adequacy of any existing warranty reserves. If outstanding warranty exposure is material, the lender may require an escrow holdback, reduce the loan amount to account for contingent liabilities, or require the seller to indemnify the buyer for pre-close warranty claims through the purchase agreement.
What EBITDA multiple should I expect to pay for a foundation repair business, and will SBA lenders finance it?
Foundation repair businesses in the lower middle market typically trade at 3.5x–5.5x EBITDA depending on crew quality, warranty record, referral network depth, and geographic market strength. SBA lenders evaluate the deal based on the business's ability to service the proposed debt at the acquired purchase price — they require a minimum 1.25x debt service coverage ratio after paying a market-rate salary to the new owner-operator. Deals at the high end of the multiple range (5x+) require particularly clean financials, low warranty exposure, and strong recurring revenue from waterproofing or service contract components to pass lender underwriting.
What is the typical timeline to close an SBA loan for a foundation repair acquisition?
From signed LOI to closed deal, most SBA-financed foundation repair acquisitions take 60–90 days. The primary variables are lender underwriting speed (PLP lenders with delegated authority are faster), the complexity of warranty liability documentation, and whether real estate is included (adding a Phase I environmental review and appraisal can add 2–3 weeks). Buyers who engage an experienced SBA lender early, prepare a complete lender package including a Quality of Earnings report, and resolve due diligence issues quickly can close in as few as 45 days.
Can a seller note be used as part of the equity injection in an SBA foundation repair deal?
No. The SBA requires that the buyer's equity injection come from personal, non-borrowed funds. A seller note does not satisfy the equity injection requirement and cannot be counted toward the minimum 10% down payment. However, a properly structured seller note — subordinated to the SBA loan and on full standby for 24 months — can be layered into the capital stack in addition to the buyer's equity injection, effectively reducing the gap between the SBA loan amount and the total purchase price.
What happens to existing warranties after I acquire a foundation repair business?
Outstanding warranty obligations transfer with the business as a legal liability of the acquired entity unless specifically carved out in the purchase agreement. As the new owner, you become responsible for fulfilling all pre-close warranty commitments unless you negotiate specific indemnification protections, escrow holdbacks, or warranty liability caps with the seller. This is one of the most important negotiating points in a foundation repair acquisition — buyers should insist on a full warranty obligation schedule, historical claim data, and a warranty reserve funded by the seller as a condition of closing.
