Dad has agreed to fix the wet basement. Good. That is consent to solve a defined problem, not consent to buy every drain, pump, liner, coating, and patented noun in the truck.

The paperwork has one job: connect the water Dad has seen to work the contractor will perform. If the contract says only “waterproofing system,” the connection is missing. A system can operate exactly as designed while the same corner gets wet.

Do not start by arguing about whether the proposal is expensive. Start by asking what the company is promising to keep dry.

Put the water problem on the first page

Walk the basement with Dad and the estimator. Mark every known entry point on a simple floor plan. Note whether water appears at the wall, the wall-floor joint, a crack, a window, a pipe opening, the floor drain, or beneath a finished wall. Photograph those places before boxes and panels hide them.

Then ask the contractor to add a sentence identifying the problem the proposed work is intended to correct. “Install interior drainage along north and east walls” describes labor. “Work is intended to collect water entering along the north and east wall-floor joints and direct it to the sump basin” describes the job.

If the contractor will not connect the proposed work to an observed entry point, Dad is being asked to buy equipment without a written statement of purpose.

Separate collection from prevention

Basement proposals often use “waterproofing” for very different work. One system may intercept water after it enters. Another may repair an exterior crack. Another may manage roof or surface water before it reaches the foundation. These are not interchangeable promises.

Ask the estimator to label each line item as one of four things: stopping entry, collecting entry, pumping collected water, or repairing damage already caused. Then check that the contract names:

  • The walls, cracks, joints, windows, or floor areas included.
  • The length and route of any drain channel.
  • The basin, pump, discharge pipe, outlet, and backup components included.
  • Where discharged water will go.
  • Who restores concrete, drywall, flooring, shelving, landscaping, or pavement disturbed by the work.
  • What known water paths are outside the scope.

A dry-looking liner is not the same thing as a dry wall. A working pump is not a promise that water cannot enter. Make the contract say which result Dad is buying.

Read the warranty as a claim form

Ignore the large number of years for a minute. Find the sentence that says what the company will do after a covered failure. “Lifetime warranty” is a label. The useful language is the remedy.

Ask these questions against the actual warranty document:

  • What event counts as a failure: visible water, standing water, pump failure, drain blockage, or damage to finished materials?
  • Does coverage apply only to the repaired section, or to the entire basement?
  • Does the company pay only for its own labor and materials?
  • Are diagnostic visits, excavation, concrete removal, access work, cleanup, and return trips covered?
  • Are drywall, flooring, furniture, stored property, mold work, and other resulting damage excluded?
  • Must Dad maintain a pump, battery, outlet, gutter, grading, or discharge line to keep coverage?
  • How quickly must a problem be reported, and by what method?
  • Who decides whether the failure came from covered work or an excluded cause?

Put every salesperson promise beside the warranty language. If the salesperson says, “We come back until it is dry,” ask for that sentence in the signed contract. Missouri consumer law treats deception, false promises, misrepresentation, and omission of material facts in a sale as unlawful practices, but a clean written record is far more useful than reconstructing a porch conversation later (Missouri Merchandising Practices Act, listed in Sources).

Circle the exclusions before Dad signs

Exclusions are not automatically crooked. They tell you where the contractor believes its responsibility ends. That is exactly why they matter.

Look for exclusions involving power loss, pump wear, clogged discharge lines, frozen outlets, groundwater pressure, plumbing leaks, sewer backups, foundation movement, new cracks, condensation, exterior grading, gutters, and work performed by someone else.

For each exclusion that could plausibly match Dad’s basement, ask one blunt question: “How would you distinguish that excluded cause from failure of your work?” Put the answer in writing.

If the company excludes foundation movement but plans to seal an active crack, ask how movement will be assessed before work begins. If sewer water is excluded, confirm that nobody is presenting the system as protection against a drain backup. If power failure is excluded, the contract should not imply that a standard electric pump protects the basement during an outage.

Find out who owns the warranty

The company that installs the system may issue the warranty itself, pass through a manufacturer warranty, or provide both. Write down the legal name, mailing address, telephone number, and email address of the party responsible for each promise.

Then check what happens if Dad sells the house, dies, moves out, or places the property in a trust. Ask whether the warranty transfers, whether notice is required, whether an inspection is required, and whether there is a transfer charge. Do not settle for “usually transferable.” Get the transfer procedure with the contract.

Also ask what survives if the installer closes. A manufacturer’s material warranty may remain while the labor promise disappears. That distinction belongs on Dad’s decision sheet.

Control changes once the wall is open

Basement work finds surprises. The contract should say that additional work requires a written change order describing the new condition, added work, price change, schedule change, and effect on the warranty. Dad or a person he names should approve it before the crew proceeds.

Do not sign a clause allowing unspecified work at an hourly rate without a cap or approval point. If the crew discovers a damaged footing, hidden pipe, unsuitable electrical supply, or blocked discharge route, stop and document it. A surprise is information, not automatic permission.

Match payment to visible stages

The proposal should state the deposit, progress payments, final payment, and the event that triggers each one. “Upon substantial completion” needs a definition. Better triggers include completion of excavation, installation of the specified drain route, pump testing, concrete restoration, cleanup, and delivery of warranty documents.

Before final payment, Dad should receive the signed contract, approved change orders, equipment information, warranty, maintenance instructions, and photographs of work that will be buried or covered. Ask for a demonstration using water so Dad can see where it travels and where it discharges.

The Missouri Attorney General’s consumer materials advise getting the price, warranty, and all conditions in writing (source list). That is not paperwork theater. It is how Dad knows when the contractor is finished.

Do not assume every signed contract has a cooling-off period

Missouri law provides cancellation rights for qualifying home solicitation sales, with a written notice requirement and exceptions. Federal rules also cover certain sales made at a home or another location away from the seller’s regular place of business. Coverage depends on how and where the sale happened, and some transactions are excluded (Missouri home solicitation statutes and the Federal Trade Commission Cooling-Off Rule, listed in Sources).

If a salesperson came to Dad’s house and obtained his signature there, find the cancellation notice in the papers immediately. Check the transaction date, cancellation deadline, seller’s address, and instructions. Keep a copy of anything sent and proof of delivery. If the notice is missing, unclear, or the contractor claims an exception, contact a Missouri consumer lawyer or the Attorney General’s consumer office before relying on a deadline.

Do not tell Dad he can sign now and sort it out later. A cancellation right, when it applies, is an exit procedure. It is not a substitute for reading the deal.

Give Dad one page he can use

Make a cover sheet for the contract. List the water entry points, included walls, promised result, exclusions most likely to matter, maintenance Dad must perform, claim contact, payment stages, and transfer procedure. Attach the marked basement sketch and photographs.

Dad keeps the decision. You make the decision legible. That is the side door when he refuses a broad takeover but will accept help checking the paper.

Tonight, put the proposal and warranty side by side. Circle every use of “waterproof,” “lifetime,” “covered,” and “excluded.” Then send the contractor one written request: identify the exact water entry covered, the remedy if it returns, and every condition Dad must maintain to keep that remedy. Do not schedule the work until those three answers are inside the contract.
