What We Do

Complete Home Protection — Below the Floor & Beyond

From crawlspace encapsulation and radon mitigation to mold remediation and basement waterproofing — we identify the root cause and fix it right the first time.

Mold Inspection & Remediation

Excess moisture creates ideal conditions for mold growth in crawlspaces, basements, and wall cavities. Our certified mold remediation team locates the source, removes contaminated material, and treats affected areas to restore safe indoor air quality throughout your home.

Crawlspace Encapsulation

A properly encapsulated crawlspace seals ground moisture, controls humidity, and protects your home's structural integrity and air quality. We install heavy-duty vapor barriers, seal foundation vents, and condition the space to keep it clean, dry, and energy-efficient year-round.

Radon Testing & Mitigation

Radon is an invisible, odorless gas and the second leading cause of lung cancer in the US. We conduct certified radon testing and install sub-slab depressurization systems that continuously vent radon safely out of your home — protecting your family's long-term health.

Basement Waterproofing

Standing water, damp walls, and seepage cracks are early warning signs of a failing moisture barrier. We install interior drainage systems, sump pumps, and exterior waterproofing solutions designed for the specific soil conditions and hydrostatic pressure patterns of the Appalachian region.

Crawlspace Insulation

Damaged, wet, or missing crawlspace insulation drives up energy costs and allows cold floors, pest intrusion, and moisture damage throughout the living space above. We remove old insulation, treat for moisture, and install high-performance insulation systems built to last in mountain climate conditions.

Know the Warning Signs

Homeowners Often Know Something Is Wrong Before They Know What It Is

Most crawlspace, basement, and radon problems go undetected for years — not because the signs aren't there, but because they start below the floor and out of sight. Clean & Dry helps you identify the root cause so you can protect your home and your family's health before the damage gets worse.

  • Musty or earthy odors coming from the crawlspace or basement
  • Standing water, damp walls, or visible seepage after rain
  • High indoor humidity, condensation on windows, or poor air quality
  • Visible mold or dark staining on joists, insulation, or walls
  • Sagging, wet, or missing insulation beneath the floor
  • Allergy symptoms or respiratory issues that worsen at home
  • Elevated radon test results or an untested home in a high-risk area
  • Soft spots in the floor, wood rot, or pest activity below the home

From basement waterproofing and crawlspace encapsulation to mold removal and radon mitigation, we recommend the right fix for what we actually find — not a one-size solution. Every assessment starts with a free inspection and an honest conversation about what your home needs.

We had elevated radon levels and a damp crawlspace and didn't know where to start. Clean & Dry came out the same week, explained everything clearly, and had both issues resolved within a few days. Professional, honest, and genuinely focused on doing the job right. Highly recommend to anyone in the High Country.

Common Questions

Answers Before You Call

Most homeowners come to us with the same questions. We've answered the most common ones here — honestly, without the runaround.

The most common signs include a persistent musty or earthy odor, visible dark staining on wood joists or insulation, increased allergy symptoms or respiratory issues indoors, and high humidity readings in the living space above. Mold in crawlspaces often goes undetected for years because most homeowners rarely go below the floor. If you notice any of these signs, a free inspection will confirm whether mold is present and how far it has spread before recommending a remediation plan.
The terms are used interchangeably by most homeowners, and both refer to the same professional process. Mold remediation is the industry term — it covers inspection, containment, removal of contaminated materials, antimicrobial treatment, air filtration, and post-clearance testing. Mold removal is simply how most people search for the same service. What matters is that the underlying moisture source is identified and corrected — otherwise mold returns regardless of how thoroughly it was cleaned.
It depends on the cause. If mold resulted from a sudden covered event — like a burst pipe or storm damage — most policies will cover remediation. If mold developed due to long-term moisture, neglected maintenance, or flooding, it is typically excluded. We work with homeowners to document the scope and cause of mold damage so you have the best possible information when filing a claim. We recommend calling your insurance provider before scheduling work to understand your specific coverage.
For most homes with a vented crawlspace, yes — particularly in the Appalachian region where humidity, seasonal temperature swings, and ground moisture create ideal conditions for mold, wood rot, and pest activity. A properly encapsulated crawlspace typically reduces indoor humidity, lowers energy bills, eliminates odors, and prevents structural damage that would cost far more to repair later. Most homeowners recoup a significant portion of the investment in energy savings alone within a few years, and the improvement in air quality throughout the living space is immediate.
Crawlspace encapsulation typically ranges from $3,000 to $8,000 for a standard residential crawlspace, depending on size, accessibility, existing moisture damage, and whether a dehumidifier or drainage system is included. Larger or more complex crawlspaces with standing water, significant mold, or damaged insulation that needs removal will fall at the higher end. We provide a written, itemized quote after a free on-site inspection — cost estimates without seeing the space are rarely accurate in this work.
Radon is a naturally occurring radioactive gas produced by the breakdown of uranium in soil and rock. It is invisible, odorless, and tasteless — undetectable without a test. When radon seeps into a home through foundation cracks, crawlspace vents, or soil contact and accumulates in enclosed spaces, long-term exposure significantly increases the risk of lung cancer. Radon is the second leading cause of lung cancer in the United States, responsible for approximately 21,000 deaths annually according to the EPA. Western NC, Northeast Tennessee, and Southwest Virginia are all in elevated radon risk zones due to the local geology.
A standard radon mitigation system installation costs between $800 and $2,500 for most homes, making it one of the most cost-effective health investments available. The most common approach — sub-slab depressurization — involves installing a PVC pipe through the foundation and a continuously running fan that vents radon safely outside. Most installations are completed in a single day. Radon levels are re-tested 24–48 hours after installation to confirm the system is working. We aim to reduce indoor radon to below 2 pCi/L — well below the EPA's 4 pCi/L action level.
Wet basements are caused by a combination of hydrostatic pressure, failed waterproofing, improper grading, or overwhelmed drainage systems. In the mountain region, freeze-thaw cycles accelerate foundation cracking and allow water intrusion that worsens each season. The fix depends on the source: surface water problems are addressed with grading corrections and downspout extensions; seepage through walls or floor cracks typically requires interior drainage systems and a sump pump; chronic hydrostatic pressure may need exterior waterproofing. The right solution starts with identifying where and how the water is entering — which is what the free inspection determines.
For most services — crawlspace encapsulation, radon mitigation installation, and basement waterproofing — you do not need to leave your home. Our crews work in the crawlspace or basement with minimal disruption to living areas. For active mold remediation, we may recommend that sensitive individuals (those with respiratory conditions, young children, or immunocompromised family members) stay elsewhere during the containment and removal phase as a precaution. We'll advise you specifically based on the scope of work before scheduling.
Yes. While our home base is Boone, NC, we serve homeowners across a wide regional footprint including Asheville and Western NC, Charlotte and the surrounding metro, the Tri-Cities region of Northeast Tennessee (Johnson City, Kingsport, Bristol), and Southwest Virginia including Abingdon and Bristol, VA.
