Corrections
The public record of claims this site published and later corrected, with the previous wording, the correction and what it changed for readers.
This page exists so that a factual error on this site leaves a trace. Every entry names what was published, what it says now, and what somebody who acted on the old version would have got wrong. Nothing is quietly edited out of a past mistake.
Three of the 13 entries below are this site correcting a claim about itself - what it offers, what it is, or where its own numbers came from. Two changed a price the site had already published. Those are the ones we would have the most reason to leave out, which is the only reason this page is worth reading.
This ledger covers everything published since the site went live in September 2026, reconstructed from the repository’s commit history. The site is new, so that is its whole life rather than a convenient starting point.

The standard
What goes in this ledger, and what does not
Published so you can hold the page to it. A corrections page padded with typo fixes hides the entries that matter, so cosmetic changes are deliberately excluded.
Recorded here
- A statement of fact about crawl spaces, soil, climate or construction that was wrong.
- A misstatement of what North Carolina code, statute or an agency requires.
- A published price or range that was wrong, or that did not come from the source it named.
- A claim about what this site is, what it does, or what it can deliver for you.
Not recorded here
- Typos, grammar, and rewording that does not change what a sentence claims.
- Design, layout and navigation changes.
- New pages, new internal links, and code refactors.
- Anything that was only ever wrong in a draft and never published.

Both guides listed a "Class I" ground retarder "sealed and taped at the seams" as a closed crawl space requirement. R409 requires 6-mil polyethylene or equivalent with 12-inch laps, and seam sealing only where the retarder is run up the walls as a full liner.
North Carolina crawl space code requirements; Vapor Barrier or Full Encapsulation?
What it said
"A Class I vapor retarder covering the ground, sealed and taped at the seams"
What it says now
"A ground vapor retarder of at least 6-mil polyethylene or equivalent over all exposed earth, with the floor graded to low spots and a drain or sump pump at each", with the optional sealed wall liner, the 3-to-4-inch inspection gap and all five drying methods now listed separately.
Why it mattered. The practical effect on what gets installed is small, but a reader was told the code names a vapor-retarder class and requires taped seams on the floor, neither of which it does, and was not told about the floor drain the code does require at each low spot.

The page said Old West Durham, Trinity Park and East Durham all grew up around the tobacco and textile mills from the early 1900s. Trinity Park grew beside Trinity College, and West Durham's mill village started in the 1890s.
Durham area page
What it said
Body: "In the older neighborhoods - Old West Durham, Trinity Park, and the mill-village districts of East Durham - housing grew up around the tobacco and textile mills between the early 1900s and the 1930s." Local notes: "Durham’s older neighborhoods - Old West Durham, Trinity Park and the mill-village districts of East Durham - grew up around the city’s early-1900s to 1930s tobacco and textile mills."
What it says now
The page now says West Durham became the Erwin Cotton Mills village from the early 1890s and was fully built out by the 1930s; Trinity Park was subdivided in 1901 beside the Trinity College campus, now Duke's East Campus; and East Durham grew as privately built housing beside the company mill villages.
Why it mattered. The advice about shallow, hard-to-inspect crawl spaces in these houses stands, but the history attached to it was wrong: Trinity Park is not a mill neighborhood, and West Durham's mill village is a decade older than stated.

The claim that the code requires a ground vapor retarder in every crawl space, corrected on four pages earlier the same day, was still on seven area pages.
Raleigh, Holly Springs, Knightdale, Wendell, Rolesville, Pittsboro and Garner area pages
What it said
Raleigh FAQ: "North Carolina's residential code requires a ground vapor retarder in a crawl space, and has for a long time". Raleigh: "Newer Raleigh homes were built with a code-required ground vapor retarder". Holly Springs FAQ: "North Carolina's residential code requires a ground vapor retarder in a crawl space, along with ventilation". Holly Springs notes: "A newer home meets the code-required minimum for crawl space moisture protection, which in North Carolina means a ground vapor retarder." Knightdale FAQ: "It will have had one installed, because the code requires it." Wendell FAQ: "built with a code-required ground cover". Rolesville: "built to a code requiring a ground vapor retarder". Pittsboro: "a code-required polyethylene ground cover". Garner notes: "since a code-required ground vapor retarder was not part of how houses were built".
What it says now
Each now says the code requires a ground vapor retarder in every closed crawl space, and in a vented one only when the builder uses the smaller vent area it allows (1 square foot per 1,500 instead of 1 per 150), or no longer makes the claim.
Why it mattered. A reader of those pages would still have treated a vented crawl space with bare soil as out of code in every case, the same misreading the earlier correction fixed on the code guide and service pages.

The site said every North Carolina crawl space must have a 6-mil ground vapor retarder. In a vented crawl space the code requires one only when the builder uses the reduced vent area it allows.
North Carolina crawl space code requirements; Vapor Barrier or Full Encapsulation?; vapor barrier service page FAQ; Holly Springs area page
What it said
Code guide: "This baseline applies whether or not the vents stay open, and it is the minimum every crawl space in the state is expected to meet". Comparison guide: "That is the minimum every crawl space in North Carolina is expected to meet, whether the vents are open or closed." Vapor barrier FAQ: "The 2018 NC Residential Code (Section R409.2.1) requires a minimum 6-mil polyethylene ground vapor retarder covering all exposed earth". Holly Springs: "Every house here was built to a code requiring a ground vapor retarder".
What it says now
The pages now say a vented crawl space needs at least 1 square foot of vent per 150 square feet of ground; the vent area may drop to 1 per 1,500 where the ground is covered with an approved vapor retarder, and when that option is used, Section R408.2 requires 6-mil polyethylene or equivalent lapped 12 inches. Every closed crawl space needs one under R409.2.1.
Why it mattered. A reader would have concluded that a vented crawl space with bare soil was out of code in every case, and could have treated a ground cover as a compliance requirement rather than a moisture decision. The vapor barrier FAQ also cited the closed crawl space section for a vented crawl space rule.

The site said North Carolina’s 2024 Residential Code became mandatory in July 2025. Its effective date has been postponed; the 2018 edition is the one in force.
Encapsulation service page FAQ; North Carolina crawl space code requirements; the source registry on the North Carolina reference and bid checker pages
What it said
Encapsulation FAQ: "North Carolina's 2024 Residential Code (Section R409, mandatory since July 2025) sets specific requirements for how it has to be done". Code guide: "falls under a separate section of the code (Section R409, closed crawl spaces), updated in North Carolina's 2024 Residential Code with a mandatory effective date of July 1, 2025." Source caveat: "North Carolina adopted the 2024 Residential Code with a mandatory date of 1 July 2025."
What it says now
The pages now say the 2018 North Carolina Residential Code is the edition in force, as the Office of the State Fire Marshal lists it, and that the 2024 edition has been adopted but postponed, with the state plumbing and heating licensing board giving May 1, 2027 as the earliest possible date. Code citations now point at the 2018 text.
Why it mattered. A reader, or a contractor checking a bid against the site, would have looked up the 2024 edition as the enforceable code. For closed crawl spaces the two editions are nearly identical, so the requirements themselves were not materially misstated, but the edition and date were wrong.

The page labelled Raleigh's close-in neighborhoods "pre-1930s". The city's own district histories date their lot sales and plats from 1907 to 1920, with building continuing to 1952.
Raleigh area page
What it said
Heading "Pre-1930s: the close-in neighborhoods", over "Hayes Barton, Bloomsbury, Boylan Heights, Cameron Park and Vanguard Park were platted between roughly 1907 and the early 1920s. Houses from that period sit on brick pier or continuous masonry foundations".
What it says now
Heading "1907 to the 1950s: the close-in neighborhoods". The page gives the City of Raleigh's dates (Boylan Heights lots on sale 1907, Cameron Park 1910, Bloomsbury platted 1914, Hayes Barton's plat filed 1920), notes that building went on to 1952, and describes foundations in the words of the city's historic district design guidelines.
Why it mattered. A reader in a 1940s or early-1950s house in Hayes Barton, Bloomsbury or Vanguard Park - nearly 50 houses went up in Vanguard Park between 1945 and 1952 - was told the neighborhood predated 1930.

The page said Hurricane Florence produced major flooding along the Neuse in Johnston County. At both of the county's river gauges it stayed below major flood stage.
Smithfield area page
What it said
"The Neuse River runs through Smithfield, and the town has a documented history of river flooding, including during Hurricane Matthew in 2016 and Hurricane Florence in 2018, both of which produced major flooding along the Neuse in Johnston County." The local notes carried the same sentence.
What it says now
The page now gives the National Weather Service gauge figures: major flooding at Smithfield begins at 20 feet; the record crest was 29.09 feet on October 10, 2016, after Hurricane Matthew; Florence crested at 18.91 feet in September 2018, moderate flooding. The Clayton page adds that gauge's figures, where Florence reached 10.62 feet, minor flooding.
Why it mattered. A reader would have ranked Florence with Matthew as a major Johnston County flood. Matthew was major at both gauges; Florence was moderate at Smithfield and minor near Clayton.

The site named Wake County as the office that issues building permits in four towns. The towns take the application and issue the permit; Wake County reviews and inspects under contract.
Knightdale, Rolesville, Wendell and Zebulon area pages; the community dataset page, CSV and JSON; North Carolina crawl space code requirements
What it said
All four area pages and the dataset gave the permit office as "Wake County Permits and Inspections (by contract with the town)", linked to wake.gov/departments-government/permits-and-inspections. The code guide's table read "| [Knightdale](/areas/knightdale/) | [Wake County Permits and Inspections (by contract with the town)](https://www.wake.gov/departments-government/permits-and-inspections) |", with the same row for Rolesville, Wendell and Zebulon.
What it says now
Each now names the town and says who inspects: Town of Knightdale Development Services, Town of Rolesville Planning (Wake County does code review and inspections), Town of Wendell Planning Department, and the Town of Zebulon, with Wake County doing the inspections in each. The code guide explains the arrangement and the reverse one in Hillsborough, Pittsboro and Youngsville.
Why it mattered. A homeowner or contractor would have gone to Wake County to apply. Wake County's own FAQ tells anyone inside those towns' limits to apply through the town, and Knightdale says its permits are reviewed, invoiced and issued by town staff. Only the inspections are the county's.

The page said Wendell's housing falls into two eras, early-1900s and recent, with very little in between. Census figures put about three in ten homes in the decades between.
Wendell area page
What it said
Hero: "Two housing eras with almost nothing in between, and a good number of properties where the drainage is entirely yours to manage." Body: "Over the past decade, large subdivisions have gone up on the edges of town. In between those two eras there is not much - which means a contractor's day here tends to alternate between houses a century apart." Local notes: "Large subdivisions have been added on the edges of town over the last decade, so the town now has two distinct housing eras with very little in between."
What it says now
The page now says the Census Bureau counts about half of Wendell's homes as built in 2010 or later, but about three in ten from 1960 through 1999 and roughly one in ten before 1960, so most of a century of construction is represented.
Why it mattered. A reader in a 1960s-1990s Wendell house - about three in ten homes there - was told that kind of house barely exists in the town, and advice framed around two extremes skipped the crawl spaces most likely to have decades-old ground cover.

The encapsulation range corrected in the cost table the previous day was still quoted, unchanged, in two guides and one city page. The cost guide also linked the statewide page as the source of the Triangle figure.
What Crawl Space Encapsulation Costs in the Triangle; Vapor Barrier or Full Encapsulation?; Raleigh area page FAQ
What it said
"For a full encapsulation system, the figure used is roughly $5,200 to $9,200 for a crawl space of about 1,200 square feet, from CrawlSpaceCosts.com's North Carolina cost guide" (linked to crawlspacecosts.com/costs/north-carolina/), with the same $5,200 to $9,200 repeated on the other two pages.
What it says now
$5,000 to $8,500 on all three pages, with the cost guide now linking the page that prints the Triangle figure (crawlspacecosts.com/guides/crawl-space-cost-north-carolina/), re-checked on 16 September 2026.
Why it mattered. For a day after the table was fixed, a reader of those pages saw a range $200 higher at the bottom and $700 higher at the top than its source, and a reader who followed the cost guide's link landed on a page with no Triangle figure at all.

The site described Piedmont clay as inherently poorly drained, and gave a drying time that no source supported. The USDA classes the soil as well drained.
Why Raleigh-Durham crawl spaces stay humid, homepage, and several service pages
What it said
"Clay soil does not drain the way sandy or loamy soil does; it absorbs water slowly and then holds onto it. A single inch of rain can keep clay soil saturated for 10 to 14 days before it fully dries out." Elsewhere: "Piedmont red clay that drains slowly and holds rainwater against the foundation for a week or more".
What it says now
The pages now say that the USDA classes undisturbed Cecil as well drained, and that the problem is what grading does to it: stripping the topsoil, compacting the clay beneath, and concentrating roof and driveway runoff at the foundation. The Triassic basin soils of Durham County and western Wake County are named separately as genuinely slow to absorb.
Why it mattered. A reader would have concluded that Triangle clay is naturally poor-draining and that nothing about their own lot mattered. The opposite is closer to true: the soil drains until a building lot is graded, which means grading, gutters and downspouts are often the actual fix - and those are far cheaper than anything installed under the house.

- Sourcing Our own claim
The headline encapsulation range was attributed to a cost guide that published a materially lower figure. The number had been adjusted upward with no record of it.
Cost table, shown on the homepage, the encapsulation service page and /cost/
What it said
$5,200 - $9,200 per home for a ~1,200 sq ft crawl space, attributed to "CrawlSpaceCosts.com, North Carolina cost guide (Triangle regional range)".
What it says now
$5,000 - $8,500, which is the Raleigh-Durham-Triangle figure the same publisher actually prints for a typical 1,200 sq ft crawl space, with the full spread across all four sources now shown in the row itself.
Why it mattered. Anyone who checked the cited page would have found $3,315 - $7,395 and no Triangle breakout, and been right to conclude the site had adjusted a number and kept the attribution. Every other row in the table matched its source exactly, which is what made this one worth finding.

- Disclosure Our own claim
The site promised a free inspection it had no ability to deliver, and no contractor had agreed to provide.
Homepage, quote form, and every service page
What it said
Get Your Free Crawl Space Inspection / "Answer a few quick questions to get your free inspection scheduled." The homepage meta description ended "Free inspection.", its hero read "tell us what you are seeing and get a free inspection from an experienced local pro", and its body read "Tell us what you have noticed and a free inspection gets booked".
What it says now
The form was retitled "Tell Us About Your Crawl Space", and the homepage offered "Free to ask, no obligation" in place of the inspection. The free inspection returned on 3 October 2026 only once it could be provided at no charge on every request it applies to.
Why it mattered. A reader would have believed a free inspection was already arranged when nobody had yet committed to providing one at no charge. What was actually free at the time was asking.
