A Railroad Town With Houses Of Every Age
Matthews grew up around a railroad depot in the 1870s and has kept growing since. That means one town holds crawl spaces under very different kinds of homes.
The first train arrives in what was then a small stop on the Carolina Central Railway line.
The Matthews Depot is established by this year on the Carolina Central Railway.
Matthews is incorporated as a town. The Massey-Clark House, now the Matthews Heritage Museum, also dates to 1879.
The depot, which later served the Seaboard Air Line Railroad, is closed by this year.
The census counts 29,435 residents, up from 22,127 in 2000.
Older homes need a careful look first
The Massey-Clark House, built in 1879 and now home to the Matthews Heritage Museum, is described as one of the oldest structures in historic downtown Matthews. Crawl spaces under older homes commonly have older plumbing, ductwork, and wiring and sometimes tight access, so the inspection comes before any liner goes in.

What the Local Climate and Soil Do to a Crawl Space
Matthews sits in the Piedmont, next to Charlotte. These are the conditions that put pressure on the space under your house.
Hot, humid summers
Matthews borders Charlotte, which has a humid subtropical climate. Charlotte’s normal July high is 90.3°F, and hot, humid days can arrive as early as May and last until the end of September. That humid outdoor air is what a closed, controlled crawl space is meant to keep out.
Rain through the year
Charlotte averages about 43.6 inches of precipitation a year, spread evenly across the seasons. Water that is not carried away from the foundation by gutters, downspouts, and grading can end up in the crawl space.
Piedmont clay subsoil
The USDA soil series named Mecklenburg, first established in Mecklenburg County, is a Piedmont upland soil with a clay subsoil that the USDA rates as moderately low in saturated hydraulic conductivity. Soil changes lot to lot, so the inspection tells us what is under your home.
Humidity is a long season
Because humid weather runs for months, the moisture does not come and go. A crawl space that stays damp for a season can show up inside the house as a musty smell, sagging insulation, or condensation on ductwork and pipes.
Climate figures are for Charlotte, which borders Matthews. Soil information is from the USDA’s official series description for the Mecklenburg soil series.
Signs It Is Time To Look Under the House
You do not have to crawl under the house to spot a problem. Two or more of these is a good reason to have the crawl space inspected.
In the house
- Musty or damp smell, worse in summer
- Floors that feel cold, soft, cupped, or buckled
- Higher cooling bills than you expect
Under the house
- Insulation sagging, wet, or falling down
- Condensation on ductwork and pipes
- Standing water or damp soil after rain
- Dark, soft, or stained wood
- Pests or signs they have moved in
On paper
- A home inspection report that flagged the crawl space
- Notes about damp soil, wet insulation, or a missing ground cover
- A buyer or lender asking for the crawl space to be addressed
What a Crawl Space Encapsulation Includes
The exact scope is set at your inspection, but a typical project works through these six parts.
Inspection and moisture assessment
We look at soil, standing water, humidity, ductwork, plumbing, insulation, framing, vents, and access, and check the outside for gutter, downspout, and grading problems.
Ground liner
A heavy-duty liner goes over prepared soil across the crawl space floor to block ground moisture.
Wall liner
The liner runs up the foundation walls so the whole space, not just the floor, is covered.
Sealed seams, piers, and penetrations
Seams are sealed and the liner is fitted around piers and penetrations so the barrier works as one system.
Vents and access sealed
Foundation vents are closed off and the access is sealed so humid outdoor air is no longer pulled through the space.
Moisture control that fits the home
One of the approved methods keeps the air in the space dry. The right choice depends on the home, and permits and licensed trades are coordinated when required.
Five Ways a Closed Crawl Space Gets Dried
Under the 2018 North Carolina Residential Code, a closed crawl space is kept dry with one of five moisture-control methods. The NC Office of State Fire Marshal has published which of them call for H-3 licensure.

H-3 licensure listedPermits in Matthews
Matthews is in Mecklenburg County, not Union County. Mecklenburg County Code Enforcement works with municipal and state authorities on local construction projects. Which method fits your home, and whether your project needs a permit or licensed trades, is decided at the inspection, and Revamp coordinates both as part of the project. The State Fire Marshal interpretation covers the 2018 codes, and codes are updated over time, so we confirm what applies when we inspect.

Straight answers to what Matthews homeowners ask us most. Do not see yours? Call 980-259-4548.
How much does crawl space encapsulation cost in Matthews?
It depends on the size of the crawl space, how much of the floor and walls need lining, whether there is standing water or damp soil, what drainage work is needed, and which moisture-control method fits the home. We do not quote a flat price over the phone. Revamp inspects the crawl space and gives you an estimate before any work is approved.
Does Revamp work in Matthews?
Yes. Revamp is based in Monroe and takes crawl space jobs in Matthews, NC. Matthews is in Mecklenburg County, right next to Union County, and it borders Stallings, Mint Hill, and Charlotte. If you are a little outside Matthews, call anyway and we will tell you what is possible.
My house is near historic downtown Matthews. Can an older crawl space be encapsulated?
Often, yes, but older homes call for a careful inspection first. Matthews was incorporated in 1879, and its historic downtown includes houses from the 1800s. Older crawl spaces commonly have older plumbing, ductwork, and wiring and sometimes tight access, so we look at what is actually there and scope the work around it instead of using a one-size-fits-all package.
Do I need a permit to encapsulate a crawl space in Matthews?
It depends on the project. Matthews is in Mecklenburg County, and Mecklenburg County Code Enforcement works with municipal and state authorities on local construction projects. The North Carolina Office of State Fire Marshal has published an interpretation of the 2018 state codes on closed crawl space moisture control. It lists five approved methods and notes that the supply-air and conditioned-space methods call for H-3 licensure, while the dehumidifier, house-air, and exhaust-fan methods do not list it. We confirm what applies to your property and coordinate permits and licensed trades when they are needed.
Will encapsulation help with Matthews humidity and a musty smell?
A sealed, controlled crawl space is designed to keep outdoor humidity and ground moisture from reaching the air under your house, and that is often what drives a musty smell. Charlotte-area summers are hot and humid, and humid days can start as early as May and last into September. Results depend on the condition of the home and the source of the odor, so we do not promise a specific humidity number or a guaranteed outcome.
Will encapsulation stop water from coming into my crawl space?
Not by itself. Encapsulation controls humidity and ground moisture, but it is not a drainage system. If water is reaching the crawl space, the fix may start with gutters and downspouts, grading, drainage, or water removal, and then the liner work. We look at where the water is coming from during the inspection so the plan fits what is really happening.
What is the difference between a vapor barrier and encapsulation?
A vapor barrier is a liner over the ground. Encapsulation is a complete system: the ground liner plus wall liner, sealed seams, piers, and penetrations, closed-off vents, and a way to keep the air in the space dry. If you only need a ground liner installed or replaced, tell us when you call and we will scope that instead.
Does encapsulation remove mold?
Encapsulation controls the moisture that mold needs, but it does not remove mold that is already growing. Mold testing and mold remediation are outside what Revamp provides for this service. If you suspect mold, a qualified mold professional should evaluate it, and we can coordinate the moisture-control work around that.
I am buying or selling in Matthews and the inspection flagged the crawl space. Can you help?
Yes. Inspection reports commonly note damp soil, wet or fallen insulation, a missing or damaged ground cover, or standing water. Send us the report with your request and we will look at the crawl space items and scope them for you.
