IICRC Certified Crawlspace Specialists Serving Middle Tennessee

Owner Colton Grimsley brings five years of technical training from an industry-leading restoration franchise to every job, now operating without corporate overhead so that every dollar you invest goes directly into quality materials and hands-on, owner-led work.

Middle Tennessee's Owner-Operated Choice
Franchise-Level Training. Independent-Level Care.
Colton Grimsley founded Advantage Crawlspace and Air after years of running a high-volume Servpro franchise in Crossville, TN. That experience built deep technical knowledge in moisture remediation, mold removal, and structural drying. What it also revealed was a simple truth: homeowners deserve direct access to the person doing the work, not a rotating crew managed from a distant corporate office. By stepping away from the franchise model, Colton eliminated mandatory royalties and rigid corporate oversight. The result is a certified water damage expert and mold removal specialist who personally inspects, repairs, and stands behind every project. When you call Advantage Crawlspace and Air, you work directly with the owner from the first conversation to the final walkthrough.

Why It Matters in Middle Tennessee
Your Crawlspace Is the Foundation of Your Home's Air Quality
Nearly 40% of the air circulating through your home originates in the crawlspace. That means moisture, microbial growth, and musty odors lurking beneath your floors are not just structural problems; they are air quality problems that affect every room and every person living inside. Advantage Crawlspace and Air addresses this reality through professional home restoration services that include crawlspace encapsulation with 12 to 20 mil reinforced polyethylene systems, vapor barrier installation, commercial-grade dehumidifier setup, sump pump installation, and thorough photo-documented inspections. Our eco-friendly moisture control methods rely on plant-based, anti-microbial treatments that are safe for children and pets, a meaningful distinction for the health-conscious families and retirees we serve across communities like Fairfield Glade, Lebanon, Cookeville, and Mt. Juliet. Every inspection includes photo documentation so you can see exactly what is happening beneath your home, giving you clear, honest findings before any repair begins. We hold a Tennessee Department of Agriculture License (Charter No. 132999) and carry a two-year workmanship warranty plus a five-year factory warranty on dehumidifier installations, because doing things the right way means standing behind the work long after the job is done.
Questions About Our Company
What Homeowners Ask Before Hiring Us
What makes Advantage Crawlspace and Air different from a large national restoration franchise?
The core difference is direct owner involvement. Colton Grimsley personally inspects, performs, and warrants every project rather than assigning work to a rotating crew. Because the company operates independently, there are no corporate royalties built into the cost of your job. That independence also means Colton can use eco-friendly, plant-based chemicals and 12 to 20 mil reinforced encapsulation systems chosen for quality rather than corporate vendor agreements. You get franchise-level technical training paired with the accountability of working directly with the person whose name is on the business.What does it mean that the company is an IICRC Certified Firm?
The IICRC, or Institute of Inspection Cleaning and Restoration Certification, sets the professional standards for the moisture remediation and mold removal industry. Being an IICRC Certified Firm means the company has met those standards for technical training, equipment use, and professional conduct. For homeowners, it means the person working on your crawlspace has been trained to industry-recognized benchmarks. It also provides credibility for realtors and property managers who need documented, certified remediation work to satisfy inspection contingencies or buyer concerns during a property sale.Is Advantage Crawlspace and Air licensed to operate in Tennessee?
Yes. The company holds a Tennessee Department of Agriculture license, Charter No. 132999. This licensing covers the application of anti-microbial treatments used during mold removal and remediation work. Combined with IICRC certification and general liability insurance, it provides homeowners with confidence that the work meets state regulatory requirements. Colton Grimsley's background includes five years of technical and operational experience at an industry-leading restoration franchise before he founded this independent company.Why does the company use plant-based chemicals instead of conventional treatments?
Conventional chemical treatments can leave residues that are harsh on treated surfaces and potentially problematic for people and pets living in the home. Advantage Crawlspace and Air uses eco-friendly, plant-based anti-microbial treatments as part of its mold removal process. This approach is particularly important for the retirees and health-conscious families the company primarily serves, including residents of communities like Fairfield Glade where indoor air quality and personal health are top priorities. The plant-based products still meet the technical requirements for effective microbial treatment while reducing unnecessary chemical exposure.What areas in Middle Tennessee does the company serve?
Advantage Crawlspace and Air serves a broad area extending roughly one to one and a half hours from Carthage and Crossville in all directions. This includes Lebanon, Cookeville, Fairfield Glade, Smithville, Hartsville, Gainesboro, McMinnville, Gallatin, and the east side of Nashville including Mt. Juliet. The company focuses specifically on Middle Tennessee because local knowledge of the region's moisture conditions and home construction patterns directly improves the quality of the work performed.What warranties come with the work performed?
Advantage Crawlspace and Air provides a two-year workmanship warranty covering the labor and installation quality of completed projects. Dehumidifier installations also carry a five-year factory warranty on the equipment itself. Transferable warranties are available as well, which is a meaningful benefit for homeowners who may sell their property, since the warranty can pass to the new owner and help satisfy buyer concerns during a real estate transaction. All findings and completed work are photo-documented to support any future warranty claims.How is pricing determined for crawlspace and mold removal work?
Pricing is determined by the job rather than a fixed service menu. Each quote accounts for the materials required, the labor involved, and the complexity of the space being treated. A crawlspace encapsulation using 20 mil reinforced polyethylene in a large or irregularly shaped space will carry different costs than a targeted vapor barrier installation in a smaller area. The company does not publish set price tiers because the variables genuinely affect the final cost. All pricing is communicated transparently with no hidden fees before any work begins.What happens during a crawlspace inspection?
Inspections are thorough assessments of moisture levels, structural integrity, and air quality conditions beneath the home. Colton conducts each inspection personally and documents findings with photos, so you receive a clear visual record of what was observed rather than a verbal summary. Moisture readings are taken and recorded as part of the process. This photo-documented approach is especially useful for realtors who need documentation to address inspection contingencies, and for homeowners who want an honest baseline before deciding on any repairs.
