The Allura siding lawsuit was a nationwide class action alleging that certain Allura fiber cement siding cracked, warped, and split within a few years of installation, far short of its 50-year warranty. The case was consolidated as a multidistrict litigation in federal court in South Carolina and resolved by a $12.5 million settlement that received final approval on May 21, 2021. The claim-filing window closed on June 21, 2023, and Judge David C. Norton granted final reversion and closure of the settlement fund in December 2025.1PACER Monitor. Kenney v. Allura USA LLC et al
What Homeowners Alleged
Allura was sold as a durable, weather-resistant alternative to wood and vinyl, backed by a 50-year warranty. Homeowners began reporting cracking, splitting, peeling, warping, and gapping between boards within just a few years of installation.
The complaints traced the problem to a manufacturing choice. Plaintiffs alleged that Allura used fly ash, a byproduct of coal-burning power plants, in place of the grain and silica sand formulations more common among competitors. Fly ash, they said, made the boards porous enough to absorb water; freeze-thaw cycles then expanded and contracted the trapped moisture until the siding cracked and failed.2Truth in Advertising. Guinn v. Allura Complaint Engineering experts retained by the plaintiffs supported the theory with microscopy and other testing on siding samples.3Angeion Group. Motion for Preliminary Approval
Allura maintained throughout the litigation that failures were caused by improper installation, not manufacturing defects, and has continued to take that position in warranty disputes outside the class action.4ABC 7 Chicago. Naperville Cracked Siding Fiber Cement
Which Siding Was Actually Covered
The settlement class was narrow. It covered only single-family homeowners whose Allura fiber cement siding came from one of two plants during specific production windows:
- White City, Oregon: manufactured between February 1 and May 7, 2014.
- Roaring River, North Carolina: manufactured between February 1, 2014, and February 18, 2015.
Multi-family buildings, commercial properties, and Plycem employees were excluded. To verify eligibility, homeowners had to remove a board and check the stamp on the back for the plant of origin and manufacturing date.5Siding Solutions. Allura Class Action Settlement Status
The damage also had to match specific criteria: cracking, bowing, shrinking, warping, breakage, or gapping greater than 3/16 of an inch. Claims where installation errors, such as overdriven nails or missing flashing, were the primary cause were disqualified.6Angeion Group. Allura Long Form Notice
How the Case Reached Settlement
The first suit was filed in South Carolina state court in August 2018, and additional cases followed in North Carolina, New York, and elsewhere.3Angeion Group. Motion for Preliminary Approval On April 2, 2019, the Judicial Panel on Multidistrict Litigation consolidated the cases as In Re: Allura Fiber Cement Siding Products Liability Litigation, MDL No. 2886, before Judge Norton in the U.S. District Court for the District of South Carolina.7GovInfo.

What Claimants Could Recover
Eligible homeowners could choose one of three payment options.
The replacement-and-repair track paid $1.00 per square foot for materials and $4.75 per square foot for labor and related costs. If 30% or more of a wall elevation was damaged, the entire elevation qualified. Homeowners received 30% of the repair award upfront and had to submit proof of completed repairs within nine months to collect the remaining 70%; failure to do so forfeited that balance. A $200 bonus applied to small projects of 20 boards or fewer, and a $1.00-per-square-foot paint allowance was available when the replacement area covered less than 30% of an elevation.8ClassAction.org.

The quick-cash option paid $4.25 per square foot of damaged area within 30 days of approval, with no requirement to show that repairs were done.9Bloomberg Law. Plycem $12.5 Million Allura Siding Class Deal Gets Final Nod
A third option paid $4.25 per square foot on approval and an additional $4.25 per square foot for remaining portions of a wall elevation once the homeowner submitted proof that repairs were completed.6Angeion Group. Allura Long Form Notice
Individual payouts varied with the size of the damaged area. Homeowners posting to a settlement tracking site in mid-2023 reported checks of roughly $4,900 and $5,200.10Top Class Actions.

Is It Too Late to File
Yes. The settlement was administered at PlycemSidingSettlement.com with a toll-free line at 1-844-530-0355, and homeowners had 24 months from the effective date to open a claim.

If Your Allura Siding Wasn’t Covered
Because the class covered only two plants and narrow production windows, many homeowners with cracked Allura siding never qualified. The gap became visible in Naperville, Illinois, where an ABC 7 Chicago investigation in 2023 documented new homes with widespread cracking. Some of those homeowners were told their product fell outside the settlement class and were left to pursue individual warranty claims instead.4ABC 7 Chicago. Naperville Cracked Siding Fiber Cement
Four Naperville homeowners took a different route and sued their developer, Oak Hill Builders and Developers, alleging the builder had substituted Allura for the James Hardie siding specified in their contracts. Oak Hill said the materials were consistent with the contract specifications and offered each homeowner $15,000 toward replacement, which the homeowners rejected as inadequate. James Hardie, which had no connection to the alleged defects, donated free replacement siding to the four families, and a local contractor called Style Exteriors installed it at a reduced cost. Oak Hill later acknowledged that eight homes in total were affected.11ABC 7 Chicago. Naperville Cracked Siding Fiber Cement Oak Hill Developers
Homeowners whose siding falls outside the class definition have no path through the closed settlement fund. Options that remain are individual warranty claims against Allura, claims against a builder who chose or substituted the product, and any state-law consumer or construction remedies available where the home is located.
