Warning signs

Seven signs something is wrong below

You do not have to crawl under the house to know something is off down there. A crawlspace problem shows up in the rest of the home first, usually as a smell. One sign is enough reason for a free look.

  • Standing water or damp soil under the home
  • A musty smell in the rooms above
  • Insulation sagging or lying on the ground
  • Cupped, springy, or cold floors
  • Condensation on ducts or pipes
  • Visible mold or dark staining on the subfloor
  • A humidity reading upstairs that will not come down

Not sure which one you need?

That is what the free inspection answers. We read the crawlspace first and recommend second.

If your crawlspace only needs a vapor barrier, that is what we quote. We will not sell you an expensive and unnecessary encapsulation to solve a simple vapor barrier problem.

How it works

Inspect. Document. Fix.

Three steps from the first call to a crawlspace that stays dry.

Inspect.

A technician goes all the way under the home, not just to the hatch. Ground cover, piers, subfloor, ducts, insulation, and vents all get looked at, with wood moisture and humidity readings taken as we go.

Document.

You get labeled photos and the actual numbers, so you can see what we saw without crawling under there yourself. Nothing gets described to you that is not also shown to you.

Fix.

We write a scope for the work the readings support, at a flat price. We say what is urgent, what can wait, and what needs nothing at all.

Why it matters

The air in your crawlspace does not stay down there

A house breathes from the bottom up. Warm air rises and leaves through the top of the home, and the air that replaces it gets pulled up from below. In a vented crawlspace, that means the damp air under your floor ends up in the rooms you live in.

That is why the first sign is usually a smell, not a puddle. It is also why a dehumidifier upstairs never fixes the problem. The moisture is coming from the ground, so the ground is where we start.

Charleston makes it worse than most places. High water tables, long humid summers, and foundation vents at grade keep pulling wet air into a space that never gets a chance to dry.

The honest middle

We would rather lose the sale than sell you something you do not need

Scare quotes are common in this trade. A homeowner gets shown a few dark photos and a five-figure number for work nobody measured. We do it the other way around. The readings come first, and the scope follows the readings.

Sometimes the honest answer is that your crawlspace needs one thing. Sometimes it is that it needs nothing at all. You will get that answer either way, in writing, with the photos to back it up.

Inspections

Termite and CL-100 inspections, documented in photos

We inspect homes and we work under them. That is why our reports come with pictures and numbers instead of a paragraph of opinion.

Whole-Home Termite Inspections

Crawlspace, framing, trim, and the exterior at grade. Every termite inspection is documented with 30 to 60 labeled photos, shared with you.
