Entry / your first ninety days
The New Homeowner Crawl Space Checklist
You bought a Hampton Roads house, so you also bought the dirt room underneath it. Ninety days of small tasks now prevents the expensive kind of surprise later.
Why ninety days
Because everything you see in month one is baseline, not symptom.
A crawl space in April and the same crawl space in late July are two different rooms. You need to have met both.
Walkthroughs cover the kitchen twice and the crawl space never. Yet the crawl space is where houses in this region quietly go wrong: high water tables, long humid summers, and framing that sits a few feet above damp soil. Whether your deed says Chesapeake on the Dismal Swamp side or a tidal street in Poquoson, the first 90 days are your window to learn the space while everything you observe is still baseline, not symptom.
Days 1 to 7
Week one
Orientation, done standing up. Nothing on this list needs a tool you do not already own.
- 01 An access you cannot open is an inspection that never happens
Find the access and make it usable
It is a hatch in a closet floor, a panel in the foundation wall, or occasionally a mystery. Locate it, clear whatever is stacked on top, and confirm it opens without a pry bar.
- 02 Month one is the only true baseline
Take baseline photos
Phone flashlight on: shoot every foundation wall, each pier line, the ductwork, and both directions from the access. Dated photos from month one turn every future question into a comparison instead of a guess about what normal looked like.
- 03 Chase the treatment paperwork too
Pull the WDI report from your closing folder
Your packet almost certainly includes an NPMA-33 wood destroying insect report. Read the findings section, note the inspection date, and file it somewhere findable. If the seller had a termite treatment done, chase the paperwork: qualifying liquid treatments carry re-treatment guarantees that transfer with the house, including our 10 year one.
- 04 Condensation on the plastic is normal, wet soil is not
Grade the vapor barrier
The plastic on the soil should cover most of the ground with seams overlapped and edges fairly tight. Note bare earth, tears, and sections shoved into corners by whoever was under there last.
Grade level
The next two months happen down here, because a crawl space only tells the truth after the weather has had a turn at it. The gap between April and July is the whole story of why Hampton Roads crawl spaces stay wet.
Days 8 to 90
By day 90
Ninety days from closing you will know this house better than the seller did.
- 01 Cheaper than dinner out
Buy a moisture meter and log readings
Probe the sills, band joists, and a few floor joists in different corners, and write the numbers down. In our market, 20 percent wood moisture is the flag line; healthy framing usually reads well below it.
- 02 Do not rush to open them all
Map the vents and note their state
Count the foundation vents and record which are open, closed, or blocked by shrubs and soil. Summer air here carries dew points in the 70s, and venting that air onto cool framing can add moisture rather than remove it.
- 03 Dry after a downpour is the best news available
Go back under after the first serious rain
Within a day or two of a real storm, look again. Standing water, puddled low spots, or a wet band along one wall tells you how the lot drains and whether the water table is part of your life now.
- 04 Cellulose on damp soil is termite food
Haul out the debris
Form boards, cut-off lumber, cardboard, old poly scraps. Builders and past owners leave cellulose under houses constantly. Bag it out once and the space stays easier to inspect for good.
- 05 Decide from your own readings
Pick your long term moisture plan
By day 90 you know whether you own a dry space to maintain or a damp one to correct. Options run from fresh vapor barrier and drainage correction up to full encapsulation with a dehumidifier. Decide from your own numbers, not from a slideshow.
If something down there worries you
Readings creeping toward 20 percent, a musty smell upstairs, white growth on a joist, or anything that looks like a mud tube: that is the moment to stop guessing. Homeowner inspections are free when a problem is suspected, and 757-583-4444 reaches us Monday through Friday, 8 AM to 5 PM. For homework in the meantime, our guides to crawl space moisture readings and encapsulation vs vapor barriers cover the numbers and the options in detail, and the moisture control and encapsulation pages show what correction actually involves.
