You have gotten three quotes for foundation repair. The prices are similar. The proposed methods are similar. But one company offers a 1-year warranty, another offers 10 years, and a third offers a lifetime warranty.
Which one should you choose? And does the warranty actually mean anything?
After 50+ combined years of standing behind our own work across New England, we have opinions. Strong ones. And since we are not exactly unbiased — we offer a lifetime warranty on all our repairs — we will try to present this as fairly as possible while also being honest about what we have seen in the industry.
Why Warranties Matter More for Foundation Repair
Foundation repair is different from most home improvements. A kitchen remodel either looks right or it does not — you know immediately. But foundation repair has a delayed feedback loop. A crack injection might look perfect on day one and fail during the spring thaw three years later. A wall stabilization might hold for a year and then shift when the next record rainstorm hits.
You need a warranty that outlasts the testing period, and for foundations in New England, that testing period is measured in years and decades, not months.
Types of Foundation Repair Warranties
Lifetime Warranty
What it means: The repair is covered for as long as you own the home, and often transfers to the next owner.
What it should cover: Re-repair or replacement if the original repair fails — meaning the crack re-opens, the injection fails, or the stabilization does not hold.
What it does not cover (even in good warranties): New, unrelated problems. If you have one crack repaired and a different crack appears three years later, that is a new issue, not a warranty claim. Fair enough.
Limited Lifetime Warranty
What it means: Lifetime coverage, but with conditions that narrow over time. For example, full coverage for 10 years, then materials only, then declining coverage.
Watch for: What the limitations actually are. Some “limited lifetime” warranties become essentially worthless after the first few years due to exclusions and depreciation schedules.
Fixed-Term Warranty (5, 10, or 25 Years)
What it means: Coverage for a specific period, after which you are on your own.
The problem: Foundation issues often do not manifest until the warranty has expired. A 5-year warranty on a crack injection sounds reasonable until you realize the real test comes during the freak storm in year 7 or the unusual freeze cycle in year 12.
1-Year Warranty
What it means: The company is warranting their labor, not the long-term effectiveness of the repair.
Our take: A 1-year warranty on foundation repair is barely a warranty at all. It covers the installation period but nothing beyond. If a company is not willing to stand behind their work for more than a year, that tells you something about their confidence in it.
Red Flags in Foundation Repair Warranties
The Warranty Is Not in Writing
If a contractor verbally promises “we will take care of it if anything goes wrong” but will not put specific warranty terms on paper, walk away. Verbal promises are worthless when the company changes ownership, the salesperson leaves, or a dispute arises.
Fine Print Exclusions That Swallow the Coverage
Read the exclusions. Some warranties exclude:
- “Abnormal” water conditions (who defines abnormal?)
- Changes in soil conditions (soil conditions always change)
- “Acts of God” (every nor’easter qualifies)
- Failure to maintain proper drainage
The last one is reasonable. The rest can be used to deny virtually any claim.
The Company Has Not Been Around Long
A 25-year warranty from a company that has been in business for 3 years is a gamble. The warranty is only as good as the company’s ability (and existence) to honor it.
We have been fixing foundations in New England for over two decades. When we say lifetime warranty, there is a track record behind those words. Ask any company offering long-term warranties how long they have been in business and check their licensing, insurance, and reviews.
Pro-Rated Coverage
Some warranties are pro-rated, meaning you pay an increasing share of repair costs as the warranty ages. A “25-year warranty” that requires you to pay 80% of the cost in year 20 is not much of a warranty.
Warranty Only Valid with Annual Inspections (At a Fee)
Some companies require you to pay for annual inspections to keep the warranty active. This creates a recurring revenue stream for them and an ongoing cost for you. It is not inherently dishonest, but it is worth knowing about upfront.
What a Good Warranty Looks Like
Here is what we believe a foundation repair warranty should include:
Clear scope: Exactly what is covered. The specific repair (crack injection, carbon fiber, wall stabilization) and what constitutes a failure.
No ambiguous exclusions: The warranty should not be defeatable by normal New England weather conditions. If your crack repair warranty excludes water intrusion during heavy rain, what exactly is it covering?
Transferability: If you sell your home, the warranty should transfer to the new buyer. This protects the buyer, adds value to your home, and demonstrates the company’s confidence in their work. See our guide on foundation repair for home sellers for more on how this affects real estate transactions.
Written documentation: A physical or digital warranty document with specific terms, the company’s contact information, and the date and description of the work performed.
No recurring fees: The warranty should not require paid inspections or maintenance contracts to remain valid. Reasonable maintenance expectations (keep your gutters clean, maintain proper grading) are fair. Paid annual inspections are a revenue grab.
Our Warranty Philosophy
We will be transparent about where we stand. Attack A Crack provides a lifetime warranty on all foundation repairs, and that warranty transfers to new homeowners.
Why? Because we use the right materials for the right situations. We do not cut corners on injection materials to save 20% on supplies. We do not rush surface preparation for carbon fiber to squeeze in an extra job that afternoon.
When the repair is done correctly with quality materials, failure is rare. We know that from decades of data. Our warranty is not a liability we worry about — it is a reflection of the work we do.
Does that mean we never get a callback? No. Foundations are complex, and occasionally a repair needs attention. When that happens, we come back, we fix it, and we do not charge for it. That is what a warranty means.
How Warranties Affect Your Decision
When comparing quotes from different companies, the warranty should factor into your total cost calculation.
Example: Company A quotes $900 for crack injection with a 1-year warranty. Company B quotes $1,100 for the same repair with a lifetime transferable warranty.
If Company A’s repair fails in year 3, you pay full price again — now you are at $1,800 for two repairs with another 1-year warranty that might fail again. Company B’s repair fails in year 3, you pay nothing for the re-repair and still have a lifetime warranty going forward.
The $200 difference in the initial quote is not a cost — it is insurance.
Questions to Ask About Warranties
Before signing with any foundation repair company, ask these questions:
- Is the warranty in writing? Can I review it before committing?
- What specific conditions would void the warranty?
- Does the warranty transfer if I sell the home?
- How long has the company been in business?
- What is the process for filing a warranty claim?
- Are there any ongoing costs to maintain the warranty?
- Does the warranty cover just the repair, or also any damage caused by a failed repair?
- Can I speak with customers who have used the warranty?
A reputable company will answer all of these questions without hesitation.
The Bottom Line
A foundation repair warranty is not just a piece of paper — it is the company telling you how much they believe in their own work. Short warranties and narrow exclusions say “we hope this works.” A lifetime transferable warranty says “we know this works.”
