Newer Doesn’t Mean Tight: Air Sealing & Attic Insulation for Olathe’s 1990s–2000s Homes
From air sealing to blown insulation, Sean, Caleb, and Luke at MyGreenKC® Insulation (Green Improvement Consulting) have worked on Johnson County homes since 2009, serving Olathe’s 66061 and 66062 ZIP codes. Olathe was founded in 1857 by Dr. John T. Barton and has been the Johnson County seat since 1859, but most of the houses standing today are far younger than the town.
Olathe has some of the youngest housing in the metro. Census estimates (ACS 5-year, 2020–2024) show a median build year of 1994, and almost a quarter of all homes were built in the 2000s alone. Builder-grade attics from those decades met the code of their day, but energy codes have asked for more insulation and tighter construction with each new edition. That’s why our crews close the gaps with BPI-certified foam first and only then top up the insulation.

How the Evergy Rebate Math Works for an Olathe Attic
Evergy supplies electricity in Olathe, and its 2026 Kansas program pays insulation and air-sealing rebates by the measure. Air sealing and R-38 ceiling insulation are priced per square foot of attic, each with a cap. Duct sealing is paid as a share of the cost, rim-joist insulation has a flat amount, and the chart lists a separate credit toward the audit. In practice, the larger the attic floor you seal and insulate, the larger the rebate, up to each cap.
Qualifying hinges on two things: Evergy wants a comprehensive energy audit on file beforehand, and it only pays when an Evergy-authorized contractor does the install. We go through Evergy’s current Kansas chart line by line with you before you sign.
Where the savings show up: most Olathe homes are on Kansas Gas Service for natural gas, though a few parts of town are on Atmos Energy. If you heat with gas, the winter savings from air sealing appear on the gas bill and the summer cooling savings appear on Evergy’s.
Olathe by Decade: What We Check in Each Era of Home
Percentages are from the Census Bureau’s housing-units-by-year-built table (ACS, 2020–2024). The checklists are the first things we inspect in homes of each age.
- Before 1960 (about 6% of homes): missing or very thin attic insulation, open wall tops, and possible vermiculite, which the EPA says to leave undisturbed and treat as if it contains asbestos.
- 1970s–1980s (about 32%): settled fiberglass, open framing gaps where walls meet the attic, and bath fans that dump moist air into the attic.
- 1990s–2000s (about 42%): two-story foyers, vaulted ceilings, knee walls and rooms over garages, where air leaks matter more than insulation depth.
- 2010 and newer (about 15%): can-light housings, the attic access panel and duct joints. Newer homes are tighter, but the gaps that remain are concentrated in a few places.
Olathe’s frontier history is still close by: the Mahaffie Stagecoach Stop & Farm is the only stagecoach stop on the Santa Fe Trail open to the public, and Black Bob Park is named for the Shawnee chief Black Bob.
Inside a First Visit to an Olathe Home
Until a specific Olathe customer gives us permission to publish their job, here is what every first visit covers. We depressurize the house with a blower door to measure air leakage, then scan the ceilings and walls with an infrared camera to find the leaks. In the attic we measure insulation depth, check the attic hatch, bath fans and duct joints, and photograph what we find. You get a written quote that puts air sealing before insulation and names the Evergy rebate measures the work fits. When we finish, we test again so the improvement is measured rather than promised.

My Olathe house was built in the 2000s. Can it really need more insulation?
It can. A 2000s attic was insulated to the code of its year, and air leaks around knee walls, vaulted ceilings and recessed lights are common in that era. The blower-door test shows whether sealing, insulation or both will help.
Which gas company serves my Olathe address?
Kansas Gas Service covers most Olathe addresses; Atmos Energy covers a minority. Your bill, or the county’s address-lookup tool, settles it.
Will air sealing lower my gas bill or my electric bill?
Usually both. If you heat with gas, the winter savings appear on your gas bill. Summer cooling savings appear on your Evergy bill.
