What the buildings here are like.
Thorntown is one of 5 towns we cover in Boone County, and half of its 480 homes were standing before 1950. That is the era we do most of our retrofit work in, and it is why we usually start with the attic and the crawlspace.
Population and housing figures: US Census Bureau, American Community Survey ACS 2024 5-year. Boone County is in climate zone 5, the colder of the two zones Indiana spans.

Old houses, and a lot of them.
49.8% of Thorntown's homes were built before 1950 — 239 of roughly 480. Houses that old were framed before anyone was sealing them: the attic is usually vented with batts thrown over the joists, and the crawlspace is open to the outside. Foam in those two places is the change people feel first.
What is around Thorntown.
From Thorntown, Lebanon is 10.8 miles south-east, Frankfort is 11.5 miles north-east, Jamestown is 13.8 miles south. Lebanon is the larger of them at 17,812 people against Thorntown's 1,212.

A small town, and we quote it like one.
Thorntown has about 1,212 people and 480 homes. In a town this size the work is word of mouth: we do one building, the neighbour sees the trailer, and we end up doing three that week. Ask us who else we have worked for nearby and we will tell you.
The oldest housing stock in Boone County.
Of the 5 towns we cover in Boone County, Thorntown has the oldest housing: the middle of it dates to 1950, against 2014 in Whitestown. Older stock is where foam makes the biggest difference, and where we find the most that was never sealed at all.
Manufactured homes and the buildings around them.
10.4% of homes in Thorntown are manufactured. We are usually called out for the pole barn, garage or shop beside one rather than the home itself, and for skirting and crawlspace work where the build allows it. Tell us what you have and we'll say honestly whether foam is the right answer.

My Thorntown house is old. Does foam still work?
It usually works better. 49.8% of homes here pre-date 1950, and buildings from that era were never sealed, so there is more to gain. We do have to look first: knob-and-tube wiring, an old roof leak or existing insulation that needs to come out all change the job. That is what the visit is for.
What does spray foam cost in Thorntown?
It depends on the building, the foam and the thickness, so we quote every job rather than publish a price. Our minimum job is $2,000. Tell us about the building and we'll come out and measure.
Which foam is right for a Thorntown building?
Boone County is in climate zone 5, the colder of the two zones Indiana spans. Open cell (R-3.8 to 4.2 per inch) is the usual choice for attics and interior walls. Closed cell (R-7.6 to 8.1 per inch) goes where moisture matters, like crawlspaces, rim joists and metal buildings. We tell you which one the building needs when we quote it.
