Nearly every page explaining basement waterproofing warranties is published by a company that issues basement waterproofing warranties. You can guess how that shapes the coverage of exclusions, transfer fees and insolvency.
This page takes the opposite approach and starts from the regulations and the court record. We sell nothing and refer no one, so there is no version of this that ends in a quote.
General information, not legal advice. Warranty and contractor law varies significantly by state, and your contract governs. For a specific dispute, talk to a lawyer or your state consumer protection office.
“Lifetime” — whose life?
This is the word the entire industry markets on, and it has no fixed meaning. In practice it resolves to at least four different things depending on the contract:
- The life of the structure
- The life of the original purchaser
- As long as you own the home
- As long as you keep paying an annual service agreement
All four are advertised with the identical word. The federal rule on this (16 CFR § 239.4) is that if an advertisement uses “lifetime” to describe a warranty’s duration, it should disclose:
with such clarity and prominence as will be noticed and understood by prospective purchasers, the life to which the representation refers.
Absent that clarification, the presumption is the life of the original purchaser — not the building, and not the next owner. Worth checking whether the page selling you a “Lifetime Transferable Warranty*” actually has a footnote where that asterisk points. Some do not.
The fourth version deserves its own warning. At least one national franchise’s own warranty page describes free service “for the period of a year”, extendable yearly, with transferability conditional on the service agreement being current. That is a subscription, not a warranty term — and a lapsed subscription can take the transferability with it.
The federal law gap nobody mentions
Most homeowners assume the Magnuson-Moss Warranty Act — the federal law that governs consumer product warranties — backs them up. For the waterproofing system itself, it largely does not.
Under 16 CFR § 700.1, building products are consumer products when sold over the counter, but:
An interior drain system, an exterior membrane, or crack injection is integrated into the realty at the time of sale. So the federal statute people reach for generally does not cover it. The same rule notes that separate items of equipment attached to the realty are consumer products — which is how your sump pump and dehumidifier can be covered by it even when the system they are part of is not.
One place the Act does reach you usefully: the Pre-Sale Availability Rule (16 CFR § 702.3) requires warranty terms to be available to you before purchase. A salesperson who will not hand over the complete warranty document until after you sign is doing the exact thing that rule exists to prevent.
Read the verb: mechanism, not outcome
This is the most consequential sentence in most of these documents and almost nobody reads it carefully. One company’s life-of-structure interior drain warranty promises — in its own words — to eliminate standing water.
“Eliminate standing water” is not “keep your basement dry.” Damp walls, seepage, humidity and mould are all outside that sentence.
Ask which one you are being sold. A warranty on a component not failing is a very different product from a warranty on a dry basement, and they cost roughly the same.
“Lifetime” sits on top of much shorter terms
The headline term covers one part of the job. Here is a real published term stack from one contractor, component by component:
| Component | Warranty term |
|---|---|
| Interior drain system | Life of structure — conditional on drain lines being clear and the pump operational |
| Wall anchors | 25 years — straightening not guaranteed; periodic tightening is the customer’s responsibility |
| 16-mil moisture barrier | 15 years, against rips and tears only |
| Dehumidifier | 5 years |
| Carbon fibre stitch weld | 5 years |
| Sump pump | 3 years |
| Electrical, masonry, demolition, rebuild | 1 year |
| Plumbing and HVAC | 60 days, in the repaired area only |
| Silicone joint and crack sealants | No warranty at all |
Exclusions that quietly gut the coverage
These are real clauses from published contractor warranty pages, not hypotheticals:
| Clause | What it means in practice |
|---|---|
| “Warranty is void if any other work is done by another contractor or individual which can directly or indirectly have an impact on any work done by…” | Read literally: landscaping, a new patio, regrading, or a plumber touching the discharge line could void it. The word doing the work there is indirectly. |
| “In no event shall you be entitled to consequential damages.” | They will redo the repair. They will not pay for ruined flooring, drywall, furniture or belongings — which is the loss you actually care about. |
| Partial system: “cove seepage only in the area serviced” | If they treated two walls and water later enters at an untreated wall, that is not a warranty failure — by the contract it was never covered. This is the most common real denial, and the salesperson sized the job to the wall that was wet. |
| Exclusions for hydrostatic pressure, soil movement, settlement, flood, acts of God | These are the mechanisms by which basements actually leak. |
| Void if water “discharges to daylight” | Most systems discharge to daylight. |
| “Warranty is not in effect unless payments are made as specified.” | Withholding final payment over defective work can extinguish the warranty covering that same work. |
Transferability — the clause that matters years later
The industry markets transferability as resale value, and terms vary more here than anywhere else in the document. Across published warranties you will find:
- No fee, unlimited transfers, tied to the address — the best version, and it exists.
- A single transfer only, after which coverage ends.
- A notification window, commonly 30 days from closing, after which transfer rights lapse.
- Conditional on a current service agreement — so a seller who stopped paying years ago has nothing left to pass on.
A seller whose basement has been dry for eight years is exactly the person who lets an annual agreement lapse, and exactly the person who then advertises a transferable lifetime warranty in the listing.
What happens if the company goes out of business
Most of these are direct contractual promises from the installing contractor. They are not insurance-backed and not bonded to the promise. If the company closes, is sold, or files for bankruptcy, there is generally no obligor left and the warranty is unenforceable in practice.
The realistic backstop is a state recovery fund, and the caps are worth knowing before you rely on them:
| State fund | Limits |
|---|---|
| Maryland Home Improvement Commission Guaranty Fund | Up to $30,000 per claimant; $250,000 aggregate per contractor across all claimants, prorated if claims exceed it. Contractor must have been licensed at the time of the work. Claim within 3 years of discovery. |
| Virginia Contractor Transaction Recovery Fund | $30,000 per claim; $100,000 aggregate per contractor per biennium. Requires an unpaid court judgment for improper or dishonest conduct first. |
Other states run comparable funds with their own caps and rules. Your state licensing board or attorney general’s office is the place to check.
What courts have actually found
Two matters of public record are more instructive than any amount of warranty advice:
A “lifetime warranty” at $40 a year
In an Indiana appellate case, the state Attorney General’s Consumer Protection Division investigated whether a national waterproofing franchise had violated the Indiana Deceptive Consumer Sales Act by misrepresenting the characteristics or benefits of warranties. The consumer complaints concerned failure to honour “lifetime warranties” offered for forty dollars annually. The court affirmed enforcement of the investigative demand.
The promise that mattered was the one not in writing
In a Wisconsin case, a salesperson told homeowners they would never have water in their basement again. They did — a later storm left it several feet deep. At trial the jury rejected the breach of express warranty, breach of contract and negligence claims. It found for the homeowners only on the state home improvement practices claim, based on the false oral sales representation. The award was $7,000, doubled to $14,000 by statute, plus roughly $41,000 in attorney fees.
The written warranty was the contractor’s shield. The unwritten promise was the homeowner’s sword. That is the reverse of what most people assume.
The practical lesson: whatever the salesperson tells you verbally, ask for it in the contract as an express warranty. If they will not write it down, that tells you what it was worth.
The failure mode nobody warns you about
Reading exclusion lists prepares you for a formal denial. In practice, complaint patterns across this industry point somewhere else: warranty work delayed for years, unreturned calls, missed appointments, and discretionary non-renewal of the service agreement that coverage depends on.
None of that requires the company to ever deny a claim, and none of it appears in any exclusion clause. Which is why the most useful question you can ask is not about coverage at all — it is about response times and what your remedy is when nobody shows up.
Questions to ask before you sign
| Ask this | What it defuses |
|---|---|
| “Whose lifetime — mine, the structure’s, or my ownership’s? Show me the sentence.” | The four meanings of one word |
| “Is any recurring payment required to keep this in force? What if I miss a year — does it reinstate or die?” | The subscription warranty |
| “Does transfer require the agreement to be current? What fee, how many transfers, how many days after closing?” | The lapsed-transfer trap |
| “Hand me the complete warranty document now, before I sign.” | Pre-sale availability — refusal is itself the answer |
| “Does this promise a dry basement, or that a component will not fail? Point to the verb.” | Mechanism vs outcome |
| “Draw on this plan exactly which walls are covered, and tell me who pays if water enters elsewhere.” | The partial-system map |
| “Write the term for each component separately: pump, dehumidifier, liner, sealant, rebuild.” | The term stack |
| “Which future projects void this — landscaping, regrading, a patio?” | ‘Directly or indirectly’ |
| “If it fails and ruins my finished basement, do you pay for contents or only redo the repair?” | Consequential damages |
| “Is this insurance-backed or your own promise? If you close, who honours it?” | Insolvency |
| “What is your licence number, and will you be licensed on the day the work is done?” | Guaranty fund eligibility |
| “Everything you just told me verbally — put it in the contract.” | The oral promise that courts actually enforce |
| “Median response time on a warranty call, and my remedy if you do not show?” | Denial by attrition |
FAQ
Is a lifetime warranty worth paying more for?
Only once you know which lifetime, whether it needs an annual payment, what it actually promises, and whether it survives the company. A shorter warranty with clear terms from a solvent contractor can be worth more than a lifetime warranty conditional on a subscription.
Does a transferable warranty add value when I sell?
It can, if it is genuinely transferable at no cost and you meet the notification window. Check whether it requires a current service agreement before you advertise it.
The company went out of business. Do I have anything?
Usually not against the warranty itself. Check whether it was administered by a franchise or third party, and check your state contractor recovery fund — caps are typically around $30,000 and often require the contractor to have been licensed.
They say the leak is not covered because it is a new spot. Is that legitimate?
If you bought a partial system, quite possibly yes — look for language limiting coverage to the area serviced. If you bought a full perimeter system, it is worth pushing back in writing and escalating to your state licensing board.
Should I get a home warranty instead?
Home warranties generally exclude pre-existing conditions and structural water intrusion, so they are rarely a substitute here. Read the water damage exclusions before assuming otherwise.
