How long after water damage can mold develop?

Mold can begin growing within 24-48 hours in Louisiana's humid climate. Prompt water extraction and professional drying are critical. If water damage isn't addressed quickly, mold remediation may be required before structural repairs. We coordinate with water mitigation companies to ensure proper dry-out before beginning structural work.

Will my insurance cover water damage repairs?

Coverage depends on the water source. Sudden pipe bursts and storm damage are typically covered; gradual leaks and flood damage may not be (flood requires separate insurance). We provide detailed documentation of all damage for insurance claims and work directly with adjusters when needed to ensure claims reflect actual repair needs.

How do you know if structural wood needs replacement?

We use moisture meters, probe testing, and visual inspection to assess wood condition. Wood that's soft, crumbling, or shows significant rot requires replacement. Sometimes sistering (adding new lumber alongside existing) is appropriate for partially damaged members. We err on the side of structural safety.

Can water-damaged wood dry out and be reused?

It depends on the extent of damage and how long the wood was wet. Short-term exposure that's quickly dried can leave wood structurally sound. Prolonged saturation often causes permanent weakness, rot, or mold that requires replacement. Professional assessment determines what can be salvaged versus what must be replaced.

Water Damage Repair

When Water Gets In, the Structure Pays. We Rebuild It.

Rotted joists, soaked sheathing, hidden mold — we repair the structural damage water leaves behind and restore your home's integrity. Serving homeowners across Metairie, New Orleans, Kenner, and Southeast Louisiana.

Step 1 · Recognize the Problem

Restoring Water-Damaged Structures

In Louisiana, water damage is constant. Hurricanes, heavy rains, plumbing failures, and chronic leaks soak framing, subfloors, and sheathing — leading to rot, mold, and structural weakness. Here's what to look for and how we fix it.

Water-damaged hardwood flooring with dark staining requiring structural repair and replacement

Water-stained hardwood flooring — a common sign of underlying structural moisture damage.

After proper dry-out and remediation, Cajun Home Services restores structural integrity by replacing or reinforcing damaged framing, subfloors, and other affected components — then puts the finishes back so the room is whole again.

Signs of Water Damage

Warped, buckled, or soft flooring
Staining on walls, ceilings, or floors
Musty or moldy odors
Peeling paint or wallpaper
Visible mold or mildew growth
Swollen or deteriorating wood trim
Sagging ceilings or soft spots
Rust stains near metal components

Spotting one or more? Catching it early limits both the structural repair scope and the cost.

South Louisiana Context

Why Water Damage Hits So Hard in Southeast Louisiana

Between hurricane-season rain bands, slow-moving tropical systems, year-round humidity above 70%, sub-grade slabs in Old Metairie and parts of New Orleans, and pier-and-beam crawlspaces along the river parishes, water finds a way in almost every home we work on. Wind-driven rain pushes past aging flashing on roofs; failed caulk and rotted trim let water behind siding and exterior envelopes; chronic shower-pan and supply-line leaks rot subfloors beneath bathrooms and kitchens; and post-hurricane storm damage often hides structural rot for months before it shows on a ceiling. By the time most homeowners call, what looks like a paint problem is usually a framing problem.

Cosmetic vs. Structural Water Damage — How to Tell the Difference

Not every water stain means the house needs structural repair. Use this as a quick decision guide before you call.

Likely Cosmetic

• Dry, isolated ceiling or wall stain from a leak that has already been fixed
• Bubbled paint with firm drywall behind it
• Discolored grout or caulk with no soft spots underneath
• Surface mold on a non-load-bearing wall, contained to one small area

Usually resolved inside a bathroom or kitchen refresh, or paint and drywall patching.

Likely Structural — Call Us

• Soft, spongy floors near tubs, toilets, dishwashers, or exterior walls
• Sagging ceilings, doors that won't latch, new cracks above openings
• Visible rot, frass, or dark stains on joists, sill plates, or rafters
• Recurring stains that come back after paint — water is still active
• Mold inside wall cavities or on framing, not just the surface

These need structural assessment and likely framing or subfloor replacement before any finishes go back. Storm-related cases often overlap with insurance-claim work.

Not sure which side you're on? That's what an assessment is for. Every project we take runs through our standard construction process — documented, permitted, and photographed daily.

Project Spotlight · Destrehan, LA

Engineered Hardwood & Subfloor Replacement After Water Rot

The existing engineered hardwood and plywood subfloor had deteriorated from prolonged water rot around plumbing in multiple wet areas. We demoed the failed flooring, replaced the rotted subfloor, sourced matching engineered hardwood, and installed new flooring across each affected room — making sure every subfloor seam was properly taped before the finished floor went down.

Leaking Toilet, Rotten Studs: Wall Retrofit & Rebuild

A slow toilet leak had been seeping into the wall cavity for years. When we opened the wall, the studs and bottom plate were rotten and mold had taken hold of the framing. We cut out the failed framing, retrofitted new pressure-treated studs and plate, installed new insulation, and hung, taped, and finished the drywall — ready for paint.

Project Spotlight · New Orleans Historic Building

Long-Term Water Intrusion in a Historic Heavy-Timber Structure

During a structural investigation on a historic New Orleans building, the bigger story above the ceilings was water. Decades of roof leaks and slow plumbing seepage had stained the original tongue-and-groove roof deck, darkened the heavy-timber rafters, and rotted the bearing ends where rafters and joists tie into the masonry walls. Below, the lower-level ceilings showed widespread mold and saturated framing around every pipe penetration. We documented the water damage from deck to bearing plate so the owner had a clear picture of what moisture had done to the structure before any repair scope was priced.

This same building was also evaluated for active termite activity — water rot and termite damage almost always travel together in old New Orleans framing. See the full termite scope on our termite damage repair page.

Water Damage and Termites: A Combined Repair Scope

In Louisiana — especially in older New Orleans buildings — water rot and termite damage feed on each other. Soft, wet wood is exactly what subterranean and Formosan termites look for, and termite galleries create new paths for water to track deeper into the framing. When we evaluate one, we evaluate both, and we price the repair as a single structural scope so nothing is left behind the finishes.
