Spray Foam Insulation in Collegedale, Tennessee

Spray foam for Collegedale homes

Collegedale is a city of about 11,100 people in southeastern Hamilton County, about 19 miles east of downtown Chattanooga. It was founded in 1916 as the site of what is now Southern Adventist University and was incorporated in 1968. The city sits in the valley of Wolftever Creek, which cuts through White Oak Mountain at Collegedale Gap.

Homes we see

Collegedale’s neighborhoods include homes built for university staff over the decades, mid-century ranches, and many newer subdivisions on the slopes around the valley. Newer homes often have two stories, bonus rooms and HVAC in the attic. Older homes often have crawl spaces and modest attics.

Common problems

• **Hot upstairs and bonus rooms.** Very common in newer two-story homes with attic ductwork.
• **Damp crawl spaces.** Homes in the creek valley and on lower ground can have humid crawls.
• **Leaky rim joists.** Long runs of rim joist leak cold air into crawls and basements.
• **Hillside basements.** Some homes are built into slopes with partly buried basements.

Where foam helps

For newer homes, foam on the roof deck is often the biggest upgrade, especially if the second-floor HVAC is in the attic. For older ranches, closed-cell foam on the rim joist and attic floor air sealing with blown insulation is a strong, affordable combination. For crawls being sealed, closed-cell foam on the walls keeps floors warmer, as long as water problems are fixed first.

Creek-valley moisture

Homes near Wolftever Creek and other low areas can have high humidity in the crawl. We check for standing water, wet framing and drainage issues. Foam should not go on damp walls, and a crawl with water issues needs drainage before foam. See humidity, mold and spray foam.

University families and rentals

Many homes near campus are rentals or are owned by staff. Foam can cut tenant complaints about hot or cold rooms and lower utility bills. We can coordinate access with tenants.

Planning around cure time

Because people and pets need to stay out while foam cures, we plan jobs around your schedule. Many families book the work for a weekend away or a school break. If you work from home, let us know so we can plan the timing.

Hillside homes and basements

Homes on the slopes of White Oak Mountain and the ridges around the valley often have partly buried basements. The exposed rim joist on the downhill side catches the wind, while the buried walls stay cool and can sweat in summer. Closed-cell foam on the rim and on dry above-grade walls helps both. Buried walls that get damp need drainage checked first.
