Foundation Warranty Guide

What to Verify in Writing Before Signing

• Length: 25 years is standard for pier installation. Lifetime is sometimes narrower.
• Scope: covers materials, workmanship, or both?
• Transferability: transferable to subsequent owners? Within what window? Fee amount?
• Performance guarantee: does the warranty guarantee “no further settlement” or only “no installation defect”?
• Exclusions list: read all listed exclusions, ask about anything ambiguous.
• Dispute resolution: arbitration clause? Where? Under whose rules?
• Bond backing: is the warranty backed by a manufacturer bond or an insurance policy? A small installer’s verbal warranty has different durability than a national-brand product warranty.

Common Warranty Exclusions

• Acts of God: earthquakes, floods, tornadoes, lightning strikes
• Neglect: failure to maintain proper drainage that caused new settlement
• Post-installation foundation modifications: added structural loads, new construction, removal of supports
• Plumbing leaks beneath the foundation that produce new settlement
• Consequential damage: cracked drywall, damaged flooring, harmed finishes
• Damage from underground utility work performed by others
• Foundation issues outside the original repair area

These exclusions track standard homeowners insurance, where the Insurance Information Institute confirms a standard policy will not pay for damage caused by a flood, earthquake, or routine wear and tear. Neither the warranty nor the policy substitutes for maintaining drainage around the foundation.

Lifetime vs 25-Year Warranties

“Lifetime” warranties sound longer but often have narrower scope than 25-year warranties. A typical lifetime warranty covers material defects in the pier system as long as the homeowner owns the property. A typical 25-year warranty covers material defects plus workmanship and may include performance guarantees (“no further settlement of the repaired area”). Read both before assuming lifetime is the better deal; sometimes the 25-year offers stronger actual coverage despite the shorter named term.

What Chattanooga Homeowners Should Verify in a Warranty

Standard warranty terms apply nationwide, but a few Chattanooga-specific points are worth checking explicitly before signing.

Hillside-installation warranty scope

Some manufacturers warrant their pier systems differently when installed on slopes above a certain grade. If your Chattanooga home is on a hillside lot in the city’s Ridge-and-Valley terrain (Lookout Mountain, Signal Mountain, Missionary Ridge), ask whether the warranty terms differ from the flat-lot standard. A 25-year warranty that excludes slope-driven movement on grades over 15 percent has substantially different value than one without that exclusion.

Transferability with Tennessee disclosure law

Tennessee sellers must disclose known foundation repair work on the property disclosure form. A transferable warranty makes this disclosure a selling point rather than a buyer concern. Confirm: is the warranty transferable, what is the transfer fee, what is the notification window after sale, who pays the transfer fee at closing (typically the seller). All four matter at resale.

Local-installer continuity

Manufacturer warranties survive the installer going out of business; installer-workmanship warranties do not. Ask whether the contractor’s workmanship warranty is backed by the manufacturer’s bond program (some manufacturers offer this), or whether it depends on the installer’s continued operation. A 25-year installer warranty from a contractor only 2 years in business carries different risk than one from a manufacturer-bonded program. When you collect quotes, ask every bidder the same warranty questions and weigh the answers against typical repair pricing.
