Insulation in Parsons, TN

A railroad town has a particular building stock. The older part of Parsons was laid out on a grid around the rail line, and the homes there date from the late railroad era through the early twentieth century and onward in layers. The oldest were built before insulation was a consideration at all: pier and beam floors over open crawl spaces, balloon framed walls with nothing in them, attics with a token layer of material that has been sitting there for decades. Decatur County itself was created in November 1845 from the part of Perry County west of the Tennessee River, and like several counties west of the river it was substantially pro-Union during the Civil War. Settlement here is old, and so is much of the housing.

The river is the other factor. A town 5 miles from the Tennessee River lives with humid air for much of the year, and a vented crawl space in that humidity never truly dries. Cold floors in winter, musty rooms in summer, and floor structures slowly taking on moisture: that is the standard condition of an older Parsons home that has never had crawl space work. It is fixable, and fixing it changes how the whole house feels.

Then the floor and crawl space. We insulate the crawl space walls and rim with closed-cell spray foam, which seals and insulates in one pass and does not absorb the river valley humidity. Where the crawl space has a persistent moisture problem, we lay out a full crawl space encapsulation scope in writing. Open wall and floor cavities get fibreglass batt insulation fitted to fill the space properly rather than stuffed into it.

• The attic in pre-war and early railroad era homes. Air sealing here does more than any other single step.
• The crawl space and rim joist. River valley humidity makes vented crawl spaces a year round moisture source.
• Floors over open crawl spaces. Pier and beam floors with nothing under them are the reason the front room is cold.
• Uninsulated walls. Many older Parsons homes have empty wall cavities. We will tell you honestly whether filling them is worth the disruption.
• Outbuildings and shops. Bare metal buildings sweat, and foam on the steel ends it.

Once we are on site, the standard is the same as it is 5 miles from our shop. We go into the crawl space and the attic, we look rather than assume, and we write the quote with the reasoning in it. Insulation only performs when it is installed without gaps, compression or missed air leaks, and that does not change with the postcode.
