Use this step-by-step exit readiness checklist to maximize your sale price, attract qualified buyers, and close a deal on your terms — whether you're 6 months or 3 years from the finish line.
Most waterproofing company owners spend decades building their business but less than a year preparing it for sale — and that gap costs them real money at the closing table. Buyers in the home services and trades space, including PE-backed roll-up platforms, SBA-financed owner-operators, and strategic acquirers like foundation repair or restoration companies, pay premium multiples of 3x to 5.5x EBITDA for waterproofing businesses that are clean, documented, and transferable. They discount or walk away from businesses with unresolved warranty backlogs, owner-dependent sales, inconsistent financials, or aging equipment. This checklist organizes your exit preparation into four phases across an 18-month timeline, giving you a clear action plan to address every issue buyers will scrutinize during due diligence. The earlier you start, the more leverage you have over both price and terms.

Buyers and SBA lenders require clean, auditable financials. Pull your P&Ls for the last three fiscal years and verify that every revenue and expense line reconciles to your bank statements and filed tax returns. If you use QuickBooks or similar software, ensure your chart of accounts is consistent year over year. Discrepancies between reported income and tax returns are one of the top deal-killers in waterproofing acquisitions.
Identify, document, and normalize all legitimate owner add-backs
Owner add-backs — personal vehicle expenses, above-market owner compensation, one-time equipment purchases, or family payroll — increase your adjusted EBITDA and therefore your sale price. Work with your accountant to compile a defensible add-back schedule. Buyers will scrutinize every add-back, so ensure each one is documented with receipts or payroll records and clearly non-recurring or personal in nature.
Eliminate or properly document cash transactions and unreported revenue
Cash payments for residential jobs are common in waterproofing but create enormous problems during due diligence. Buyers cannot include unreported revenue in their valuation, and cash-heavy books often disqualify businesses from SBA financing entirely. Begin running all payments through documented channels — checks, ACH, or card processing — and issue proper invoices for every job starting now.
Obtain a preliminary business valuation from a broker experienced in home services
Before you can improve your position, you need to know where you stand. Engage a business broker or M&A advisor who has sold waterproofing or adjacent trades businesses to provide a preliminary range of value based on your current financials. This baseline tells you which improvements will generate the highest return on your time and effort before going to market.
Audit all active warranties and document remaining terms, coverage scope, and historical claim rates
Warranty liability is the single most unique and scrutinized risk factor in waterproofing acquisitions. Buyers — especially PE platforms — will demand a complete schedule of every active warranty, including issue date, customer name, coverage type (interior drain tile, exterior membrane, crack injection, sump pump), and remaining term. Pull every warranty certificate ever issued, build a spreadsheet, and calculate your historical claim rate as a percentage of jobs completed. If your claim rate is below 5%, that is a selling point. If it is higher, address the underlying installation quality issues now.
Create written SOPs for estimating, installation, and warranty service processes
If only you know how to price a job, diagnose a wet basement, or manage a warranty callback, your business is not transferable — and buyers will price that risk into their offer or walk away. Document your estimating process, job costing methodology, installation standards for every system you offer (interior drain tile, exterior waterproofing, crack injection, sump pump installation), and your warranty service workflow. These SOPs do not need to be perfect — they need to exist and be usable by someone other than you.
Build or clean up your customer database with job history, revenue, and contact information
A buyer acquiring your waterproofing business is also acquiring your customer relationships, warranty obligations, and referral network. If that data exists only in your head or in paper files, it has no transferable value. Export your job history from your estimating or accounting software, add customer contact details, job types, revenue per customer, and date of last service, and organize it in a CRM or at minimum a clean spreadsheet. Flag your top 20 customers by lifetime revenue and identify any single customer exceeding 15% of annual revenue — that concentration will require a mitigation plan.
Develop a recurring revenue program if one does not exist
Buyers pay premium multiples for predictable revenue. If you do not already offer annual maintenance agreements, sump pump inspection contracts, or drainage system service plans, launch a basic program now and begin enrolling existing customers. Even 50–100 active service agreements generating $50,000–$150,000 in annual recurring revenue can meaningfully shift your buyer profile from SBA-only buyers to PE platforms willing to pay 4.5x–5.5x EBITDA.
Verify all contractor licenses, bonds, and insurance certificates are current and confirm transferability
Waterproofing contractors are licensed at the state and sometimes local level, and requirements vary significantly across jurisdictions. A lapsed license or non-transferable bond can delay or kill a closing. Pull every license, bond, and certificate of insurance your business carries, confirm renewal dates, and work with your attorney to understand which are personally held by you versus held by the entity. Licenses held by you personally — not the business entity — will need to be re-obtained by the buyer, which adds cost and delay they will price into their offer.
Create a complete equipment and vehicle inventory with current valuations and maintenance records
Buyers conducting due diligence on a waterproofing company will physically inspect every truck, trailer, injection rig, sump pump installation kit, dewatering equipment, and power tool in your fleet. Build a detailed inventory spreadsheet listing each asset, its year, make or model, current condition, estimated fair market value, and service history. Address any deferred maintenance now — a $4,000 repair on a spray rig that a buyer discovers during inspection can become a $20,000 price reduction request.
Transition customer relationships and sales responsibilities to a project manager, foreman, or sales manager
This is the hardest and most important step for most waterproofing owners. If customers call you directly, if you do all the estimates, if your crews rely on you to make daily decisions — you are the business, and buyers know it. Over the next 6–12 months, deliberately transfer customer relationships to a trusted employee. Start attending fewer site visits, copy your project manager on customer emails, and introduce them by name on estimates and invoices. The goal is that your best customers know and trust someone else before you go to market.
Assess key employee retention risk and implement retention incentives
Your licensed waterproofing technicians, crew leads, and any estimator or project manager on staff are core assets a buyer is acquiring. If any of them are likely to leave when you sell, that risk will be factored into deal terms. Identify your two or three most critical employees, have candid conversations about their future with the business, and consider implementing a retention bonus tied to staying through a post-closing transition period. Document employment agreements or at minimum written offer letters for all field staff.
Clean up the balance sheet — resolve any outstanding liens, disputed invoices, or deferred tax liabilities
Buyers purchasing your waterproofing company through an asset sale will want a clean balance sheet with no hidden liabilities. Resolve any outstanding mechanic's liens on completed jobs, collect aged receivables, settle any disputed vendor invoices, and work with your accountant to address any deferred tax obligations that could create post-close surprises. A business with a clean balance sheet closes faster and with fewer price adjustments.
Engage a business broker or M&A advisor with verified home services or trades transaction experience
Selling a waterproofing company is not the same as selling a retail store or software business. You need a broker who understands warranty liability, seasonal revenue patterns, SBA eligibility requirements for trades businesses, and how to position your mix of residential and commercial work to different buyer types. Ask any broker you interview for references from waterproofing, foundation repair, restoration, or similar trades transactions they have closed. A specialist will run a broader buyer process and negotiate better terms than a generalist.
Prepare a professional confidential information memorandum (CIM) highlighting your value drivers
The CIM is the primary marketing document a buyer receives after signing an NDA. It should present your waterproofing business clearly and compellingly — highlighting your recurring maintenance contracts, Google review reputation, crew licensing, geographic service area, equipment fleet, and financial performance. Work with your broker to present adjusted EBITDA with a clean add-back schedule, document your warranty management process, and show three years of revenue trend data. A well-constructed CIM positions you as a serious seller and attracts higher-quality buyers.
Establish your walk-away price and deal structure preferences before entering negotiations
Before your first buyer conversation, know your minimum acceptable price, your preferred deal structure (all-cash at close versus earnout), your transition availability (6 months versus 12 months), and any non-negotiables around employee retention or the business name. Sellers who enter negotiations without these anchors often accept below-market terms under deal pressure. Work with your M&A advisor to model out SBA deal structures, PE roll-up offers with equity rollovers, and earnout scenarios so you can evaluate any offer clearly.
Build and document your online reputation and inbound lead generation systems
A waterproofing company with 200+ Google reviews, consistent 4.5-star ratings, and documented inbound lead volume from organic search is worth meaningfully more than one that relies on owner referrals. In the months before going to market, actively solicit Google reviews from satisfied customers, verify your Google Business Profile is complete and accurate, and document your monthly inbound lead count, lead sources, and close rates. Buyers — especially PE platforms — place significant value on defensible, non-owner-dependent lead generation.

Most waterproofing businesses with $1M–$5M in annual revenue sell for 3x to 5.5x adjusted EBITDA. Where you land in that range depends on several factors specific to your business: whether you have recurring maintenance contracts or rely entirely on project revenue, how much of the business depends on you personally for sales and estimating, the size and documentation of your active warranty backlog, the condition of your equipment fleet, and the consistency of your financials over the past three years. A business with clean books, documented recurring revenue, transferable licensing, and an operating team that functions without the owner will consistently command multiples at the top of that range. A business with owner-dependent sales, cash revenue, or unquantified warranty exposure will see meaningful discounts. The best way to get a specific number is to engage a broker with home services transaction experience for a preliminary valuation before you begin your exit process.
Warranty liability is one of the most closely scrutinized issues in any waterproofing acquisition. Buyers will want a complete schedule of every active warranty — customer name, installation type, coverage terms, and expiration date — along with your historical warranty claim rate. Most buyers address this in one of three ways: they price a warranty reserve into the purchase price (typically a percentage of active warranty exposure), they require you to maintain a warranty escrow account for 12–24 months post-close, or they purchase their own warranty liability insurance through a specialty carrier. The best thing you can do before going to market is document all active warranties completely and be able to show a low historical claim rate. Sellers who cannot produce this documentation often face 10–20% purchase price reductions or escrow holdbacks to compensate buyers for the unknown liability.
Yes — owner dependency is consistently one of the top discount factors in waterproofing and home services acquisitions. If you handle all the estimates, manage all the customer relationships, and your crews rely on you for daily direction, a buyer is essentially buying a job rather than a business. SBA lenders will scrutinize this as a repayment risk, and PE platforms will either reduce their offer significantly or require a longer transition and earnout period to protect against revenue loss when you leave. The solution is not to hire a CEO — it is to systematically transfer customer relationships to a trusted project manager or estimator, document your estimating and sales process in writing, and demonstrate over 6–12 months before going to market that the business operates predictably without you in the field every day.
It depends on what 'not clean' means. Minor inconsistencies in how you categorize expenses, a few years of owner add-backs that were not formally documented, or some variance in annual revenue are all manageable with proper preparation and a good M&A advisor. What becomes difficult — and sometimes fatal to a deal — is unreported cash revenue, significant discrepancies between P&Ls and tax returns, or personal expenses run through the business that were never documented. SBA financing, which most buyers of waterproofing businesses rely on, requires 3 years of tax returns that support the purchase price. If your tax returns significantly understate your actual earnings because of unreported cash or aggressive deductions, your buyer pool may be limited to all-cash or PE buyers who can accept more complexity. Starting now to run all transactions through documented channels and working with an accountant to normalize your financials over the next 1–2 years will meaningfully expand your buyer options and sale price.
Plan for 12–18 months from the time you begin preparation to the time you close. The first 3–6 months should be spent on financial cleanup, warranty documentation, and operational improvements before you go to market. Once listed with a broker, finding and qualifying a buyer typically takes 3–6 months. Due diligence, SBA loan approval, and closing paperwork add another 60–120 days. Sellers who try to rush this process — going to market before their financials are clean or their warranty obligations are documented — typically either fail to close or accept significantly below-market terms. Sellers who invest 12 months in proper preparation before listing consistently achieve better prices and cleaner closings.
That depends on your revenue size, financial profile, and how transferable your business is. If your waterproofing company generates $1M–$2.5M in revenue with clean SBA-eligible financials, your most likely buyer is an owner-operator from a construction or trades background — often someone from foundation repair, restoration, or general contracting who wants to add waterproofing to their existing service offerings and will use an SBA 7(a) loan for 80–90% of the purchase price. If you are generating $2.5M–$5M with documented recurring revenue, a trained crew, and a project manager in place, you become attractive to PE-backed home services roll-up platforms that are actively consolidating regional waterproofing operators. These buyers often pay higher multiples but may include equity rollover components or earnouts tied to post-close performance. Strategic acquirers — drainage contractors, foundation companies, restoration firms — can also be strong buyers at any revenue level if your service area or customer relationships are complementary to their existing business.
