After the Storm: What to Check on a Grand Strand Mobile Home

September 3, 2026

The dangerous thing about storm damage to a manufactured home is that most of it is not visible when the storm ends. Wind damage announces itself. The damage that costs the most is done to the ground under the home while the water is standing, and the home does not react to it for months.

This is the walkthrough worth doing in the week after a named storm or a heavy rain event, before the connection between the two gets forgotten.

First, the delay problem

Horry County’s soil is coastal-plain sand over a high water table. A manufactured home sits on piers, each concentrating a very large share of a fifteen-thousand-pound-plus structure onto a footprint about the size of a dinner plate.

Saturated sand under that load compacts and migrates. It happens while the ground is wet, which is to say during and immediately after the storm. But the home does not visibly respond, because the frame is stiff enough to bridge a pier that has dropped half an inch. The water goes down, the yard dries, everything looks normal.

Then in the spring a door stops latching, and nobody connects it to last September.

This is why post-storm checks are worth doing on homes that took no obvious damage at all. Florence in 2018 dropped 23 inches of rain on the county, put the Waccamaw at a record 21.16 feet at Conway, and flooded around 2,000 homes, many outside mapped flood zones. Ian in 2022 pushed 5 to 6 feet of surge across the Grand Strand and left up to three feet of sand on South Waccamaw Drive in Garden City. Both left a long tail of homes that settled quietly afterward.

The outside walk

Do this first, and do it before the ground dries out, because the evidence disappears.

Look for washout channels. Where did water run? Follow the scour marks. A channel that ran near a pier line has carried sand out from under a pad, and the home has not dropped yet only because the pier is still bearing on what is left. This is the most urgent finding on the list.

Check for new low spots or holes anywhere around the perimeter, especially at corners and along the long sides.

Look at the skirting. Buckled panels, gaps opened at the top, panels pushed in or floated out. Skirting damage is mostly cosmetic, but a new gap is how animals get to your belly wrap, and a gap that opened because the home dropped toward the ground is telling you something else entirely.

Check the grade. Storms move dirt. A lot that used to shed water away from the home may not anymore, which turns a one-off event into a permanent drainage problem.

Look at the anchors. Every strap should be tight. Grab each one. Check the anchor shaft where it enters the ground for corrosion and for any sign it has pulled or tilted. Near the beach, salt corrosion at the ground line takes anchors out while the visible parts still look fine.

The under-home look

If you can safely get under, or when someone does:

Standing water. Note where it is and how long it stays. Water that clears in a day is a grading problem; water that sits for weeks is a drainage problem with a bigger number attached.

Pier pads. Sunk, tilted, cracked, or with the sand scoured out from beside them. Reset runs $75 to $150 per pier, rebuild $150 to $400.

Piers. Push on them. Anything you can rattle by hand is carrying nothing.

The belly wrap. Storm water gets into a belly through existing tears and then has nowhere to go. Wet insulation sealed inside a belly does not dry, it holds moisture against your subfloor, and that is the beginning of a floor replacement. Patch $300 to $800, full re-wrap $1,200 to $4,500. This is the check most worth doing and least often done.

Ductwork. Water in the belly plus ducts running through it is how you get a home that smells wrong for two years.

The inside walk, now and again in six months

Right after the storm, note the baseline: which doors latch, whether any floor slopes, whether the marriage line on a doublewide is tight. Do the marble test in three rooms and write down which way it rolled.

Then do it again in six months. The change between the two readings is the storm’s actual bill, and having the first reading is what turns a vague suspicion into something you can act on.

The settling self-check is the same list, scored, if you want it structured.

What to do about insurance

Two things worth knowing, and neither is legal advice.

Document before you clean up. Photographs of washout channels, standing water, and displaced skirting are worth having whether or not you end up filing. Once the ground dries and the yard gets tidied, the evidence is gone.

Understand what a policy typically covers. Sudden events are generally covered; gradual deterioration generally is not. Post-storm settling sits awkwardly between the two, which is exactly why documenting the storm event and the condition immediately afterward matters. Ask your carrier the question directly rather than assuming either answer.

Getting on a schedule after a storm

Be realistic about this. After a named storm, every crew in Horry County books out at once, and it stays that way for weeks. Post-Florence the wait stretched badly.

Two things follow from that. The homes seen soonest are the ones that called soonest, so if you have found a washout, call rather than waiting to see whether it gets worse. And the best time to have the straps and piers checked is before the season, not during it. Hurricane season peaks in September, which means the useful version of this article is the one you read in May.

The honest summary

Most homes come through most storms fine, and we would rather tell you that than sell you a check you do not need. The under-home inspection is free, it takes about half an hour, and if your piers, pads, straps, and belly are sound you will be told so and there will be no follow-up call.

What is not fine is assuming a home that looks normal a week after a flood is a home that came through it. The sand under your piers moved whether or not anything creaked.
