Spray Foam Insulation

South Pittsburg sits on the Tennessee River at the base of the Cumberland Plateau in Marion County, and the position of the town creates a set of insulation challenges that are unique to this specific geography. The river-level humidity in summer is substantial. The cold that settles into the river valley in winter comes off the plateau above town and pools along the water in ways that make an under-insulated building significantly more expensive to heat than the temperature alone would suggest. Homes along 3rd Street, the older neighborhoods near the historic downtown, and properties backing against the Tennessee River all deal with a moisture and thermal load that spray foam insulation addresses more completely than any other product. Prince Insulation has been serving Marion County since 1980.


The business added spray foam capability in 2010. Dewayne Hill runs the operation out of Decherd with three spray rigs and twelve full-time employees. When South Pittsburg homeowners search for spray foam insulation near me, Prince Insulation is the company with actual field experience in Marion County river-bottom building conditions.

What River-Bottom Living Does to Uninsulated Homes

South Pittsburg's position at the Tennessee River creates ground-level moisture conditions that don't exist in upland locations. River-adjacent soil stays saturated for extended periods after rain events, and that moisture finds its way into crawlspaces through inadequate vapor barriers and through foundation vents that weren't designed for the humidity levels present in this location. The homes along the river bluff in South Pittsburg have been managing this for generations. The solution isn't seasonal maintenance. It's a properly installed encapsulation system with closed cell spray foam at the foundation perimeter.

Closed Cell Spray Foam for Foundations and Crawlspaces

South Pittsburg's river-bottom moisture conditions make closed cell spray foam the right product for crawlspace and foundation applications. It doesn't absorb moisture, it provides vapor impermeability at the foundation perimeter, and it contributes structural rigidity to the rim joist framing where it's applied. Combined with a properly sealed ground vapor barrier and mechanical dehumidification, it creates a crawlspace system that holds stable conditions regardless of what the river and the soil are doing outside. Prince Insulation installs the full system.

Spray Foam Insulation for Attics

Marion County summers at river level are hot and humid, and South Pittsburg attics in older homes absorb heat through the day and release it into the living space through the evening. Spray foam insulation at the roofline converts the attic from an unconditioned heat reservoir into a semi-conditioned zone that moderates temperature swings and significantly reduces cooling loads. For homes with HVAC equipment or ductwork in the attic, the efficiency improvement from roofline foam is particularly substantial. Prince Insulation assesses each South Pittsburg attic before recommending the specific application approach.

Fiberglass Insulation for Floor Systems and Walls

Not every South Pittsburg application requires spray foam. Prince Insulation installs fiberglass batts correctly in wall and floor applications where spray foam isn't the appropriate solution. Four decades of fiberglass installation experience in this region means the details are handled: no compression, full coverage to the framing perimeter, penetrations addressed. Fiberglass installed correctly performs at its rated value. Most of what Prince Insulation finds in older South Pittsburg homes was not installed correctly.

Vapor Barriers and Moisture Control Systems

South Pittsburg's Tennessee River proximity means vapor barrier installation is one of the most important interventions available for many properties in this community. Prince Insulation installs heavy-gauge barrier material, properly lapped, sealed, and supported, as part of a complete crawlspace moisture management system. Dehumidifiers that are sized to the crawlspace volume and calibrated to target humidity ranges complete the system for properties where passive barriers alone aren't sufficient.

Why South Pittsburg Property Owners Choose Prince Insulation

The crew at Prince Insulation is made up entirely of full-time employees. No subcontracted labor is dispatched to South Pittsburg projects. The spray equipment is owned and maintained by the company. The workmanship is licensed, insured, and guaranteed by a business that has operated continuously in the region since 1980.


Spray foam insulation contractors who don't have experience in river-bottom building conditions bring approaches calibrated for different moisture loads. Prince Insulation's crew has been in South Pittsburg crawlspaces and knows what the Tennessee River bottomland does to building assemblies that weren't designed to handle it.

Key Benefits

South Pittsburg homeowners who address the foundational moisture and insulation issues in their homes through spray foam insulation see results that extend beyond utility costs. Crawlspace encapsulation stops the musty air and elevated humidity that river-bottom soil moisture produces in unencapsulated crawlspaces. Attic insulation and air sealing reduce cooling loads through a river-valley summer that runs hot for months. Properly applied spray insulation in a South Pittsburg home produces permanent building performance improvements that accumulate in value over time.
