Shawnee & Lenexa Insulation Upgrades Backed by Blower-Door Numbers
In Shawnee and Lenexa, homes from the 1970s sit beside homes from the 2010s. MyGreenKC® Insulation (Green Improvement Consulting) has served these neighborhoods since 2009. Sean, Caleb, and Luke answer the questions, do the testing and stand behind the work.
Mostly 1970s-and-later homes: ACS estimates (2020–2024) put the median year built at 1990 in Shawnee and 1992 in Lenexa. The 1970s account for about 17% of Shawnee homes and 20% of Lenexa homes, and in Lenexa another 18% went up in the 2010s. Every era leaks in its own way, so we measure first and seal with spray foam before adding any insulation.

Case Notes: Testing, Sealing and Communication
“… He hooked up some kind of vacuum seal on the front door, and showed me how much air was leaking around the house. He looked at the attic to check the insulation, and it was deficient as well. Sean sent me a very detailed report, with pictures, and gave me his suggestions along with the prices. … I had them foam the rim joists in the basement, did the whole home air seal and added much needed insulation. … I was very impressed, and would encourage anyone that is wanting to save money on utilities and have a more energy efficient home to contact them. …”

“I was very impressed with the work Luke and his team performed. … I have also seen monthly savings on my electric bill. … The thing I was most impressed with is the their communication skills. GIC was running 15-20 minutes to our initial appointment, however I was notified by a team member in a timely manner which allowed me to accommodate my schedule. Coming from the service industry, this is something that I was greatly appreciative of. …”

Reading Linda’s Review as a Case Study
Linda D.’s review walks through the whole process. Here is each step in order, with what we were checking for:
- The vacuum seal on the front door is the blower door. It turns “the house feels drafty” into a single leakage number that can be retested later.
- The attic check confirms whether the existing insulation is too thin, uneven or damaged. In her house it was deficient.
- The detailed report with pictures sets out options and prices so the homeowner decides, not the crew.
- Rim-joist foam, a whole-home air seal and added insulation come in that order: leaks first, then insulation.
- “Encourage anyone … to contact them” is the outcome we’re after: a house that feels tighter, and a homeowner who’d send a neighbor. Evergy’s Kansas program adds its own steps, explained below.
Matt R.’s note about a heads-up call when we were running late matters too. Good communication is part of the job.
Shawnee and Lenexa, Neighborhood by Neighborhood
A Shawnee Indian mission was set up here in 1831, and Shawnee was laid out as a town in 1857. Quantrill’s raiders burned it in October 1862. Lenexa was platted in 1869 by railroad engineer Octave Chanute and named for Na-Nex-Se, the widow of Shawnee Chief Black Hoof. In the 1930s Lenexa called itself the Spinach Capital of the World, and it still holds a Spinach Festival every September.
- 1950s–70s ranches and split-levels: about a third of Shawnee’s homes. Expect settled insulation, unsealed top plates and open soffits.
- 1980s–90s subdivisions (roughly a third of homes in each city): vaulted living rooms, recessed lights and partly finished basements with open rim joists.
- 2000s–2010s construction (about 28% of Shawnee and 37% of Lenexa): two-stories with bonus rooms over the garage and cantilevered floors.
Shawnee Mission Park, at 79th and Renner in Shawnee, covers 1,600 acres and has a 120-acre lake. Local history goes back further than the houses: in 1857, twelve years before Lenexa was platted, James Butler Hickok (later known as Wild Bill) staked a 160-acre claim at what is now 83rd Street and Clare Road.
Gas Company, Electric Company, and the Rebate Rules
Both city websites list Evergy for electricity. For gas, Lenexa and Shawnee each list both Kansas Gas Service and Atmos Energy; your gas bill shows which one serves your house. Both cities list WaterOne for water. Spire doesn’t serve this side of the state line.
Evergy’s Kansas rebates cover air sealing, ceiling insulation, rim joists and duct sealing, but only after a qualifying audit and only if the contractor is authorized before installation. You can check our status on Evergy’s contractor finder. We’ll confirm the current terms for your house before any work is scheduled.
Shawnee & Lenexa Solutions
1. Deep Blown-In Attic Insulation
Once the leaks are sealed, we blow insulation to an even depth, from ranch attics to the low spaces above bonus rooms.
Explore Attic Insulation →2. Attic Insulation Removal
Insulation damaged by squirrels or mice, or soaked by an old roof leak, gets vacuumed out and the attic cleaned before anything new goes in.
Explore Insulation Removal →3. BPI Air Sealing & Spray Foam
We foam cantilevered floors, garage ceilings and rim joists. We also seal can lights and top plates in the attic.
Explore Air Sealing →4. $499+ Blower-Door & FLIR Audits
Audits use a blower-door test, which pulls air through the house to reveal leaks, and an infrared camera. Both are repeated after the work so you can see the change.

My gas bill says Atmos, not Kansas Gas Service. Does that change anything?
Not for the insulation work. Gas-company programs differ, so we look up the current terms for whichever company is on your bill.
Do you need to test before quoting a newer home?
We recommend it. Newer homes tend to leak around garages and cantilevers rather than through the attic floor, and the test shows exactly where.
Can you work around a finished basement?
Yes. If the rim joist sits behind drywall, we can often reach it from a utility room or a soffit. Where we can’t, the report shows the leak so you can plan for it during a future project.
