Vintage Rug Cleaning
If you have just bought an old rug secondhand in the Cape Fear coast, it has been sitting through damp spells that run to 39 days at a time, 211 days of the year in total. At 16 frosts a year against 17 days over ninety degrees, this is a one-season climate as far as a stored rug is concerned, and nobody in New Hanover County, NC watches that season accumulate.
Vintage, or Semi-Antique? Wilmington Sellers Use Both
The word on the tag is vintage, and in New Hanover County, NC it is the one that finds the rug. It is not the one that describes it.
The trade calls the same rug semi-antique: old enough that the dyes and the spinning are not modern, young enough that no New Hanover County, NC dealer is treating it as a museum piece.
The oldest housing we collect from in the Cape Fear coast goes back to the 1870s — Historic District and Forest Hills among them — and rugs of roughly that generation are still circulating across New Hanover and Brunswick counties. That generation is most of what gets sold as vintage around Sunset Park.
So the rug is tested before it is wetted. A semi-antique dye bleeds into undyed wool where a modern one will not, and a rug out of Carolina Place washed as though it were new is how a pale field goes pink.
What a Wilmington Listing Leaves Out
What you bought is the rug, not its last decade. An estate sale, an auction lot, a flea-market stall or a booth around Downtown Wilmington hands over no storage history at all, and in New Hanover and Brunswick counties that history ran through 55.6 inches of rain across 133 days a year.
That place took 211 damp days a year with only 16 frosts to interrupt them. A garage around Bald Head Island therefore never gets cold enough to stop anything and never dry enough to undo it.
Historic District, Wrightsville Beach and Carolina Beach include houses raised on piers, which ventilates the underside of a floor without drying it.
The air under a raised floor is outdoor air, so anything stored there tracks the outdoor figure directly, and the outdoor figure here is at or above the mold threshold 211 days a year with runs reaching 39 days. A rug put under the house, which is where many of them in New Hanover County, NC go, is outdoors with a roof.
Landfall and Porters Neck are close enough to water that the ground under a floor stays wet even across this market's 154 sub-threshold days, so the dry part of the year does less than the figure suggests.
What Wilmington Air Has Already Done to It
The days mold needs no patience for
Of this market's 211 damp days, 155 reach 80% relative humidity or higher, and in New Hanover County, NC that second figure matters more than the first.
At 75% mold is possible given weeks, which most storage does not get; at 80% it stops needing much time at all, which 155 days a year here do give it. So that is 155 separate opportunities rather than a slow background risk, and a rug out of a Middle Sound Loop outbuilding has sat through several years of them.
The level it never gets below
Mean relative humidity here is 75.1%, and the useful way to read that is as a floor rather than an average: wool in New Hanover County, NC is never allowed to get properly dry.
Wool sitting at equilibrium in 75.1% air holds a standing charge of moisture permanently, and for an old rug out of Sunset Park that has one specific consequence. The dyes of this period are the ones that move when wet, so a semi-antique rug already sitting at 75.1% is closer to bleeding than a modern one before anybody has touched it — which is why colors are tested on arrival from Ardmore before any water goes on, not after.
What happens overnight
The daily average understates New Hanover County, NC badly. Mean relative humidity of 75.1% sounds survivable, but the air reaches 95% at some point on 42.9% of days, and nearly all of that is overnight.
So a rug in an unconditioned space around Sunset Park takes a small wetting and a small drying every day of the warm season, on top of the 211 days that sit above the threshold outright.
Daily cycling is harder on an old foundation than a steady load, because each of those 42.9% of days is a dimensional change rather than a dose. The damage accumulates where the rug is fixed — the selvedges, and the knots holding the fringe in — which is why a rug out of New Hanover County, NC storage goes at its edges first.

Wash First, Then Price the Repairs — Wilmington
We wash first, then price the repairs, and the order is not administrative. Until the soil is out there is no telling what is damage and what is only dirt — and on a rug bought secondhand in New Hanover County, NC that distinction is the entire decision. A rug that looks ruined is often carrying years of Wilmington dust over sound wool; a rug that looks fine sometimes has nothing left to sew into.
In New Hanover County, NC the thing under the soil is usually mold that has already moved out of the pile and into the cotton, where washing reaches it and airing does not. Until it is out, a repair is being stitched to a foundation that may not hold the stitch.
So the order is: photographs first, then we tell you what is visible in them and what is not, then the rug is collected from Downtown Wilmington and washed, then it is read on the bench with the soil gone. The repair estimate lands where it is worth having — once the rug can actually be seen, and before anybody in New Hanover County, NC has committed to the work.
Send Photographs of the Rug
Front, back, and a close view of anything that looks wrong. Damage from 16 freezing nights a year tends to run in lines rather than patches, so a shot taken along the rug in raking light helps. Nothing but a way of reaching you is required.
