A Postwar Boom City
Spray Foam Insulation in Shawnee serves a city that grew suddenly. Shawnee had 845 residents in 1950, 9,072 in 1960 and 20,946 in 1970, and it reached 67,311 at the 2020 census. Its roots go back much further: a Shawnee Indian mission was set up here in 1831, the town was laid out in 1857, and Quantrill's raiders burned it in October 1862.
Housing by decade
Point2Homes data shows 9.3% of Shawnee homes from the 1960s, 16.8% from the 1970s and 13.6% from the 1980s, with more since. The older homes need attic sealing, blown-in and rim foam. Newer western subdivisions have larger homes with bonus rooms and vaulted ceilings.
Homes rarely empty
The 2020 census counted 26,465 housing units, with a homeowner vacancy rate of 0.7%. About 73.7% of homes are owner-occupied. Most Shawnee houses are lived in and heated year-round.
Space and parks
Shawnee covers about 42.86 square miles, and Shawnee Mission Park takes up 1,600 acres with a 120-acre lake. Many homes sit on larger lots with detached garages or shops, which we can insulate too.
Evergy rebate
If Evergy supplies your electricity, its 2025 Kansas chart lists rebates for air sealing, ceiling insulation and rim joist insulation through December 31, 2027.
Typical Shawnee plan
For a 1970s Shawnee house, a common plan is: seal the attic floor, blow insulation to depth, foam the rim joist and seal cantilevers. For newer western subdivisions, it is usually bonus rooms, vaulted ceilings and specific attic spots. Each area is priced separately.
Shops and garages
Shawnee's larger lots mean more detached garages and shops. If you heat yours, closed-cell foam on the walls and ceiling seals and insulates in one step. If it is metal, foam also stops condensation drip.
Owners who stay
With 73.7% of homes owner-occupied and almost no empty houses, most Shawnee owners plan to stay put. Air sealing and insulation pay back over time and make the house more comfortable from the first season.
