Cary by the numbers

Cary sits mostly in Wake County, with parts in Chatham and Durham counties. The 2020 census counted 174,721 residents, and the Census Bureau's July 1, 2025 estimate (PEP Vintage 2025) is 183,582, roughly 5% more in five years.

The American Community Survey (ACS 2020–2024 5-year) describes the housing like this:

Median year built: 1999
About 12% of homes built before 1980, and only about 1.4% before 1960
About 26% built in 2010 or later
About two in three homes owner-occupied (33.4% rented)
Median home value: $580,200

That is a different mix from Durham, where about 30% of homes predate 1980. In Cary, the usual mold story is less about old plaster and more about air conditioning, attics and plumbing in homes that are 20 to 40 years old.

Where Cary mold calls tend to start

Weather at Raleigh-Durham International Airport averages about 46 inches of rain a year, with July and September the wettest months, about 52 days at 90°F or hotter, and summer dew points in the upper 60s (NOAA 1991–2020 normals). These are general patterns, not findings about any home.

Vents, ducts and air handlers

An AC that runs all summer pulls water out of humid air. A clogged condensate line, a sweating supply duct or an oversized unit that cools without drying can leave spotting around ceiling vents.

HVAC and duct mold

Attic roof decking

Roofs on homes built in the 1990s and 2000s are reaching replacement age. Small leaks at flashing, and bath fans that dump moist air into the attic, can stain the decking long before a ceiling shows it.

Attic mold

Crawl spaces

Where a Cary home sits over a crawl space, summer air matters. A field study funded by the U.S. Department of Energy found that wall-vented North Carolina crawl spaces often stayed above 80% relative humidity in summer, conditions it tied to mold growth.

Checking a company before you hire

NC rules box. North Carolina does not license mold inspection or remediation companies, so checking credentials is up to you. Look up IICRC certification on the IICRC Global Locator and ACAC credentials at acac.org/find, ask for a current insurance certificate, and for rebuild work of $40,000 or more, check the general contractor license at portal.nclbgc.org (G.S. 87-1). State health guidance advises hiring a consultant who does not also do the remediation. That is best practice, not a legal requirement.

Ask for a written scope
It should say what gets removed, how the area is contained, and how the moisture source will be fixed.
Ask who checks the result
Independent clearance testing after the work is a common best practice. See post-remediation verification.
Read the warranty terms
Get them in writing, including what voids them if the leak comes back.
Know your cancel right
If you sign in your home, G.S. 14-401.13 generally gives you until midnight of the third business day to cancel sales of $25 or more. Whether it applies depends on the sale.

Mold cleanup and like-for-like drywall replacement in a single-family home usually need no building permit if the job is $40,000 or less and does not touch load-bearing framing, plumbing design, or HVAC or electrical work (G.S. 160D-1110(c)). Your contractor should confirm with the inspections office that covers your address. For published price ranges, see the mold remediation cost guide.

Cary mold questions

Which county is my Cary home in?

Most of Cary is in Wake County, but the town also reaches into Chatham and Durham counties. Mold rules are the same statewide because North Carolina has no mold license. County lines matter more for property records, flood maps and which inspections office handles a rebuild permit, so give your street address when you ask for quotes.

My Cary house was built in the late 1990s. Is that old enough for asbestos?

It is less likely than in a pre-1980 home, but age alone does not settle it. If a company plans to cut out flooring, ceilings or old duct wrap, ask whether an asbestos inspection is needed first. The NC Health Hazards Control Unit answers questions at 919-707-5950.

Do I need mold testing before I get quotes in Cary?

Not always. The CDC says it does not recommend routine mold testing, and state health guidance puts a careful visual inspection first. Testing helps when you smell mold but cannot find it, or when you want independent clearance after the work. Ask who would do that testing and whether they are separate from the remediation company.
