Rotted Deck Joists Aren't Cosmetic. Epp Replaces Before Collapse

Yes. Deck joist rot is one of the failure modes the Consumer Product Safety Commission tracks for collapse injuries. Epp Foundation Repair treats any rotted deck joist as urgent because deck collapses almost always happen during a gathering when the load is highest. Dave Epp's protocol is to recommend the deck be unloaded. Furniture, grill, occupants. Within 48 hours of confirmed rot and not used until structural repair is complete. About 1 in 6 rotted-deck inspections Epp performs ends with a written recommendation to take the deck out of service until repair.

Epp Foundation Repair anchors pricing to joist count and access. Sister-joist installation on a deck runs $300 to $600 per joist. Replacement runs $400 to $800 per joist. Hanger and hardware upgrades add $20 to $40 per connection. Most rotted-deck joist projects involve 4 to 12 joists because rot rarely affects a single member. Typical project totals are $2,000 to $8,000 for joist and hanger work, with deck-builder coordination for ledger and surface work running an additional $2,000 to $10,000. Written estimate after on-site inspection reflects your scope.

No. Epp Foundation Repair is a structural framing contractor. Sister joists, replacement joists, hangers, posts, beams. Deck-board removal, replacement, fastening pattern, railing replacement, stair tread replacement, and surface restoration are a licensed deck builder's scope. Epp completes the structural repair, signs off in writing, and refers to a deck contractor for the surface restoration. This scope boundary is part of why the BBB awarded the Integrity Award in 2011 and 2016.

Sometimes, but it requires a licensed deck builder, not Epp Foundation Repair. The ledger-flashing replacement involves removing decking back 24 to 36 inches from the house wall, removing the siding above the ledger, installing new flashing membrane and Z-flashing, and re-installing siding and decking. Dave Epp recommends a deck builder do this work and stays in scope on the structural joist repair. Epp coordinates the schedule when both trades work the same project.

Usually not. Standard policies exclude gradual deterioration, wood rot, and lack of maintenance. Which covers more than 95 percent of rotted-deck cases Epp sees. Sudden events like a tree falling on the deck or vehicle damage sometimes qualify. Check with your carrier; Epp Foundation Repair has worked with most major insurers on the rare covered claim and can document the damage cause for the adjuster.

Epp Foundation Repair categorizes deck rot in three severity tiers. Tier 1. Localized rot under 30 percent cross-section, hangers intact. Allows continued use at normal loads while waiting up to 30 days for repair. Tier 2. Rot exceeding 30 percent, hangers showing corrosion. Requires limiting use to two people and no heavy items until repair within 1 to 2 weeks. Tier 3. Joist ends rotted into hangers, multiple joists affected, visible deflection. Requires immediate removal from service until structural repair is complete. Dave Epp writes the severity tier and use restrictions in the Customized Repair Estimate.
