Crawl Space Mold Removal in North Myrtle Beach, SC

"Very punctual and thorough."

Mike K. · Google review

Take the screen off a foundation vent behind a Cherry Grove channel house in August and the smell reaches you before the flashlight does, which is where Crawl Space Mold Removal in North Myrtle Beach, SC usually begins.

Owners rarely go under their own floor, so the news travels upstairs: a smell in the hallway after the house has been shut up a week, or carpet on the water side that stays clammy through three days of sun.

Twice a day, the water comes up the channel.

Parts of Cherry Grove sit on made ground. The inlet between Futch Beach and the Nixon land was filled in 1950, and the 1970s turned the marsh behind the beach into a grid of channels with house lots between them. Those channels are the finger canals the docks and back yards line up on today, and on a lot like that the tide sits close under the floor and moves twice a day.

The older lots toward the Intracoastal Waterway behave the same way. Windy Hill was built by Conway investors after World War II, and the state encyclopedia describes the layer before it plainly: simple frame houses, some built on stilts, along the oceanfront. Little River, farther north on the Waterway, takes the heaviest rain totals on this end of the coast. A house on piers has an open void underneath, and whatever the ground and the air are doing out there, the joists are doing too.

The city’s hazard notes say North Myrtle Beach floods from the Atlantic, from the Intracoastal Waterway and inland from the Waccamaw, and they define tidal flooding as low ground going under during exceptionally high tides, at full and new moons. Those notes are written about streets. The water reaches the crawl space on the same tide.

June through September, the vents work against you.

The weather record for North Myrtle Beach comes from a station inside the city, at Grand Strand Airport. Ten years of observations there put the average daily high dew point at 77.2°F in July and 76.2°F in August, with the average overnight low holding above 65°F from June until the end of September. An average of 134.4 days a year reach a dew point of 70°F or higher.

Foundation vents were drawn on the assumption that outside air dries a crawl space out. Through a coastal summer it does the opposite. Research on hot, humid climates is direct about it: the outdoor air is usually damper than the framing under your floor is cool, so the water condenses on the wood instead of leaving with the breeze (Building Science Corporation on crawl spaces). Run a cold supply duct through air like that and you get beads on the metal, dark streaks on the joist above, and insulation that never dries out.

The week after a storm tide.

On the north end, surge does more damage than rainfall. Isaias in August 2020 was a light-rain storm that still put 12 to 18 inches of tide water over Sea Mountain Highway, four blocks in from the beach, and two years later Ian pushed water through the Cherry Grove streets again. Neither one needed a hurricane’s worth of rain to fill a crawl space.

A crawl space takes that water first and gives it back last. Salt water wicks into the bottom of batt insulation and stays there. A vapor barrier that should shed water holds it in a low spot. Duct wrap dries on the outside and stays wet in the lining. The street is dry by morning; the space under the floor is still damp in November, when the smell reaches the hallway.

If you have never checked which zone your lot sits in, the county publishes a lookup: Horry County flood maps. It tells you how often the water is expected to get to you, which is worth knowing before you decide what to fix first.

The day we treat, and what still holds a year later.

Our VaPURE process is patented, and because the sterilant goes in as a vapor it reaches band joists, wall cavities and the inside of duct runs that a spray wand never gets to. A protectant then goes onto surfaces to help the wood resist regrowth once the water is dealt with. That minimizes tear-out in most cases, so insulation, ductwork and subfloor generally stay put, and most crawl space jobs finish in a single day.

You stay out of the house while we treat and for a short stretch afterward, and that goes for pets and houseplants as well. Every job carries a workmanship guarantee, and that is the only guarantee we make.

Before we put a number on the job.

Nothing goes on paper until someone has been down there with a light and a moisture meter. Footprint matters, and so does headroom, because a space you can kneel in works quicker than one you drag equipment through flat. The insulation counts too: batts that are sagging, soaked or lying on the ground take handling that dry ones do not.

Then there is the water. Standing water has to be pumped out and traced back to where it came in before treating makes sense, and a crawl space that floods on spring tides is a different proposition from one that got wet once in a named storm. Duct condition moves the number as well, since that is the route between the ground and the rooms upstairs.

We treat what is growing; we do not seal. Encapsulation, drainage, a dehumidifier and bulkhead repair belong to other trades, and under a North Myrtle Beach house a closed crawl space is the researched answer rather than more vents. What we will do is tell you where the water is arriving, because the treatment lasts as long as the dry does.

Frequently Asked

Crawl Space Mold Removal questions, answered.

Get the standing water out and the space dried first, by a drying company if it is more than a wet-vac job. Photograph the insulation and the duct runs before anything is pulled. Then call us. Treating a surface that is still wet, or due to get wet again on the next spring tide, buys you nothing.

If contractors are due within a few weeks to dig, pump or open the ground, let them finish. Treating and then letting machinery churn the same space wastes the work. If the repair is months out and the smell is already in the house, treat now, on the understanding that the moisture source decides how long it holds.

A vapor barrier that is intact, lapped and turned up the piers, not a sheet with tears in it. Gutters and grade that carry rain away from the footing. Duct joints that are not leaking cold air. Clemson puts indoor moisture between 30 and 60 percent; a vented crawl space here rarely gets near that in August without help.
