A Small Town Turned Subdivision Hub
Spray foam insulation in McCordsville is mostly about newer homes. Wikipedia lists 1,134 residents in 2000, 4,797 in 2010 and 8,503 in 2020, with a 2025 estimate of 13,094. Housing units nearly doubled from 1,717 in 2010 to 3,028 in 2020, with only 2.9% of them vacant. The town was platted in 1865 but did not incorporate until 1988, so most of what stands today was built in the last twenty-five years.
Young homes, young families
The 2020 census put the median age in McCordsville at 35.6. A lot of homeowners here bought new and plan to stay, and they call us when a few rooms never feel right: the bonus room, a bedroom over the garage, or a basement that stays chilly. Those complaints usually trace to a handful of spots the builder could not seal well.
The usual new-home fixes
We check the rim joist in the basement or crawl space, the floor over the garage, the attic hatch or pull-down stair, recessed lights and bath fans in the top-floor ceiling, and any knee walls around upstairs rooms. Closed-cell foam on the rim and garage ceiling, weatherstripping and an insulated cover on the hatch, and sealing around fixtures fix most of it. If the attic is accessible, adding blown-in above the builder's level is a cost-effective upgrade; the Department of Energy recommends up to R-60 in Climate Zone 5.
Open land around town
McCordsville sits in Vernon Township with farmland still around many subdivisions. Open fields mean more wind against the house, and wind pushes air through every gap. Sealing pays off a little more on an exposed lot.
Slab-on-grade and crawl space homes
Not every McCordsville house has a basement. Homes on crawl spaces should have their crawl space checked for a sealed vapor barrier and insulated walls or floor. Slab homes lose heat at the slab edge, which is hard to fix after the fact, so attic sealing and depth become even more important.
Keep the receipts
If you are adding insulation to a newer home, keep the quote and invoice with the material, R-value and area. They are useful when you sell and for any utility rebate paperwork.
Basements
If you have an unfinished basement and plan to finish it, have the rim joist and walls insulated before framing. The Insulation Institute's summary of the 2020 Indiana Residential Code lists R-13 or R-10 continuous for basement walls in Zone 5, and Hancock County is in Zone 5A, per OpenEI. Get a free estimate

McCordsville Questions
Why is the bedroom over my garage cold?
The floor sits over an unheated garage and is often poorly sealed. Foam in the garage ceiling usually fixes it.
Should I add attic insulation to a newer McCordsville home?
Often it is worth it. Code calls for R-38; DOE recommends up to R-60 in this zone. We seal first, then add depth.
Can you insulate my basement before I finish it?
Yes. That is the best time for the rim joist and walls.
My home is on a slab. What can be improved?
The attic usually offers the most. Sealing the attic floor and adding depth reduces heat loss and summer heat gain.
