What Is Subfloor & Framing Repair (Rot / Water Damage)?

A standards-led program to remove compromised wood, correct the underlying moisture cause, and rebuild structural members to code and manufacturer tolerances.

Immediate Actions (What to Do Now)

  1. Limit foot traffic over soft, bouncy, or visibly damaged areas.

  2. Shut water to suspected fixtures and mark the affected rooms.

  3. Save mitigation records (photos, moisture logs)—they guide scope and insurance.

  4. Call our 24/7 dispatcher for a structural assessment and temporary stabilization if needed.

Common Scenarios We Handle

  • Toilet, tub, or shower leaks rotting OSB/Plywood and joists below

  • Dishwasher/ice-maker leaks under kitchens causing soft spots and sag

  • Slab or crawlspace humidity wicking into subfloor and rim joists

  • Washing-machine overflows damaging laundry platforms and adjacent rooms

  • Window/roof leaks traveling through walls to plates and rim areas

  • Historic/older homes with undersized spans and chronic moisture

Our Structural Repair Process (Step-by-Step)

Source Diagnosis & Safety

Identify plumbing/roof/HVAC causes; secure utilities; temporary shoring if needed; map affected assemblies (thermal + moisture meters).

Mitigation & Dry-Down

Extract and dehumidify; chamber the area with LGR dehumidifiers + directed airflow; daily RH/GPP and wood moisture readings to local baseline.

Selective Demo & Assessment

Remove failed finishes and compromised subfloor/plates/joists; evaluate spans, bearing, corrosion, and insect/pest evidence; plan repairs.

Structural Repairs & Upgrades

Subfloor: Replace with correct thickness/grade, glue + ring-shank fasten, stagger seams, meet flatness tolerances.

Framing: Sister or replace joists, repair rim/sill/plates, add blocking/bridging; install hangers, straps, and anchors as required.

Moisture/Envelope Corrections

Replace gaskets/pans/valves, improve venting and drainage, add vapor barriers, seal penetrations, and address crawlspace conditions.

Finish Readiness & Close-Out

Install underlayment where specified (tile/stone), plane high spots, fill lows, perform squeak and deflection checks, and deliver a close-out packet (photos, readings, materials).

What’s Included

  • Leak/source repair and moisture control plan

  • Chambered dry-down with logged RH/GPP and moisture readings

  • Selective demolition of damaged subfloor/framing to sound edges

  • Code-correct carpentry (joist sistering/replacement, blocking, hardware)

  • Subfloor install & leveling to finish tolerances (adhesive + fasteners)

  • Documentation packet (photos, materials, readings, finish readiness)

Costs & Timelines (What to Expect)

  • Typical duration:
    Small bath or laundry area: 1–3 days structural + dry times.
    Kitchen/multi-room or crawlspace work: 3–6+ days depending on access and scope.

  • Key cost drivers: Size/thickness of subfloor, number/length of joists to sister/replace, hardware quantity, access (crawlspace vs. open), moisture mitigation runtime, and required underlayment for tile/stone.

  • Clear estimate: Line-item scope separating source repair, structural work, and finish prep—easy to share with adjusters.

Insurance & Claims Help

  • Carrier-ready evidence: Before/during/after photos, moisture logs, framing/subfloor material specs, and a narrative tying cause → damage → repairs.

  • Supplements: Hidden rot at plates/rim or extended spans uncovered mid-repair are documented promptly.

  • Coverage notes: Policies vary on long-term seepage vs. sudden events. We provide clean separation of resulting damage and any code upgrades.

Risks of Waiting (Why Act Now)

  • Structural sag and bounce worsen, cracking finishes and grout.

  • Mold/odor growth in wet wood and insulation.

  • Pest intrusion via softened plates and gaps.

  • Higher costs as damaged areas spread and finishes must be re-done.

Methods, Materials & Quality Standards

  • Moisture targets: Wood to local baseline before close-in.

  • Subfloor materials: Correct plywood/OSB grade & thickness, APA stamps, adhesive + ring-shank/screw schedule.

  • Flatness/deflection: Meet ⅛″ in 6′ / 3⁄16″ in 10′ (typical) and L/360 for tile (L/720 stone, project-specific).

  • Hardware: Code-listed hangers, straps, anchors, corrosion class matched to environment; proper nails/fasteners—not drywall screws.

  • Underlayment systems: Cement board or uncoupling membranes for tile; approved vapor/underlayment for LVP/engineered wood.

  • Site controls: Soft containment, HEPA air support, clean egress, and daily housekeeping in occupied spaces.

Frequently Asked Questions

Can we patch the subfloor without pulling all the tile?

Only if damage is localized and structure allows a backed, glued, and fastened patch to sound edges. Many cases require full-area replacement to meet flatness/deflection.


Do you always sister joists?

We sister or replace based on decay depth, span, and load. Sometimes blocking/bridging and hardware upgrades are added for stiffness.


Will you coordinate with my flooring installer?

Yes—we deliver finish-ready tolerances and share flatness readings so your installer can proceed confidently.


What about crawlspace moisture?

We address vapor barriers, vents, grading, and leaks, and can add dehumidification where needed.


Is this covered by insurance?

Sudden/accidental losses often are; long-term seepage may not be. We provide the documentation your adjuster expects.


Can we stay in the home?

Usually. We phase work, set containment, and keep egress clean. For large spans or structural shoring, brief access limits may apply.
