Tropical Depression Luis made landfall in Isabela on August 3, and the southwest monsoon — enhanced by Tropical Depression Maymay — has kept dumping rain across Luzon since. Barangays in Macabebe, Pampanga went underwater as high tide met floodwater; homes across the region are only now starting to dry out. If yours was one of them, the instinct is to grab a mop, repaint, and move on. That instinct is what turns a ₱30,000 repair into a ₱300,000 one.
Floodwater doesn't just ruin paint — it saturates the soil under your footings, corrodes rebar inside CHB walls, and can hide structural damage behind a freshly repainted surface. Before you call a painter, run the checklist below. Then use the calculator to get a realistic repair budget.
If floodwater stood above 0.6m (knee height) for more than 24 hours, or you see new cracks, a lean, or a door/window that suddenly doesn't close right, get a structural inspection before any repair work starts. Cosmetic fixes over a compromised structure hide the problem — they don't solve it.
If the electrical panel itself was submerged, do not touch it — call your electric cooperative or a licensed electrician to de-energize the line from outside first. If the panel is dry and reachable, switch OFF the main breaker before wading into any room with standing water.
Walk the perimeter. Check for new diagonal cracks in walls, a visible lean in posts or walls, sagging in the roofline, or a gap that has opened between the wall and the floor/roof. Any of these means: do not enter, call an engineer.
If you smell gas, leave immediately and ventilate before re-entry. Watch for floating debris that may have battered walls or posts during the flood peak.
Open doors and windows for at least 30 minutes before spending extended time inside — trapped humid air accelerates mold growth and can carry contaminants from floodwater.
Foundation & Footings
Check for new settlement (a corner of the house that now sits lower than the rest), gaps opening between the foundation and the wall, or soil that has visibly washed away from around the footing. On sloped or backfilled lots, also check for signs the retaining structure moved. These are the highest-cost issues to miss — differential settlement gets more expensive to fix the longer it's ignored.
Walls (CHB, RC, or Wood Frame)
Look for cracks wider than a hairline (>3mm), especially diagonal cracks radiating from window/door corners — these can indicate movement, not just surface damage. White powdery residue (efflorescence) and paint bubbling below the waterline are expected and cosmetic on their own, but combined with cracking they point to a wall that absorbed more than surface moisture.
Columns, Posts & Floor Slab
Check columns and posts for a visible lean using a level or plumb line. On the floor slab, look for new heaving, cracking, or a hollow sound when tapped (a sign the slab has separated from its base). A slab that heaved during the flood and settled unevenly afterward is a red flag for soil movement below.
Electrical & Doors/Windows
Any outlet, switch, or panel that was submerged needs professional inspection before re-use — corrosion inside the housing is invisible from outside and is a fire and shock risk. A door or window that suddenly binds, won't latch, or has a new gap at the frame is often the first visible sign of frame racking from structural movement — worth flagging even if it seems minor.
Once you know whether you're looking at cosmetic repair or a structural fix, the next question is budget. This calculator gives a realistic 2026 Philippine price range based on flood depth, affected area, and finish type — separate from any structural engineering fee.

Flood recovery is a documentation problem as much as a construction problem. These three AEDO-built apps cover the parts homeowners and contractors struggle with most:
GPS- and timestamp-verified before/after photos of every damaged room — the documentation format insurers and LGU disaster assistance programs ask for. ₱1,499 lifetime, free tier available.
Get PhotoStruct →Dictate your inspection notes in Filipino, Cebuano, or English — it turns voice notes into a polished PDF report you can send straight to your engineer, contractor, or insurance adjuster. ₱499 lifetime.
Get Field Report →Turn the calculator estimate above into a full, room-by-room bill of quantities with 2026 Philippine unit prices — useful for comparing contractor quotes or supporting an insurance claim. ₱999 lifetime.
Get Unit Cost Analysis →Is it safe to re-enter a flooded house?
Only after power is confirmed off at the source and a visual check from outside shows no lean, large crack, or sagging. If the electrical panel was submerged, have a professional de-energize it — never handle a wet breaker panel yourself.
Does floodwater weaken a house's foundation?
Yes, potentially. Standing water saturates soil around footings and can reduce bearing capacity temporarily; fast-moving water can also scour soil away from footings entirely. Houses on backfilled or reclaimed lots are at higher risk and should be checked first.
How much does flood damage repair cost in the Philippines?
For moderate flooding (0.3–0.6m), expect roughly ₱800–₱1,500/m² for wall repair and ₱900–₱2,500/m² for flooring replacement, plus ₱15,000–₱60,000 if electrical work is needed. Use the calculator above for a range tailored to your flood depth and area.
How long should I wait before repainting or re-flooring?
Allow roughly 4 days of active drying per 0.3m of flood depth. Closing up a wall or laying new flooring over material that's still damp traps moisture and causes the repair to fail within months.
A cosmetic repair over a genuine structural issue doesn't fail immediately — it fails during the next flood, or the next earthquake.
