Platte City Homes: Which Utility Serves You, and What Your Attic Needs
Platte City, the seat of Platte County, has a different utility mix than most of the metro, so this page starts there. Sean, Caleb, and Luke of MyGreenKC® Insulation (Green Improvement Consulting) have handled insulation and air sealing in the Northland since 2009.
Two building booms: Census ACS figures (2020–2024) give Platte City a median build year of 1978. About 35% of homes date from the 1960s and 1970s, and another 22% from 2000–2009. These are survey estimates for a small city, so treat them as approximate. Homes from each boom fail in different ways, so every visit starts with a blower-door test, and spray foam goes into the leaks before any insulation is added.

Start With Your Utility Bill
- Electricity: the city lists two providers. The Missouri PSC’s locator shows Platte City on Evergy Missouri West, and the Platte County Landmark has reported that Platte-Clay Electric Cooperative (PCEC) serves some newer areas near the city’s southern limits.
- Natural gas: inside Platte City, the city’s Local Utilities page lists Liberty Utilities (Liberty/Empire), and the Missouri PSC locator shows Empire District Gas for the city. Spire is the gas company the same locator lists for many nearby Platte County communities, including Parkville, Riverside, Platte Woods and Weatherby Lake.
- Water and trash: the City of Platte City inside city limits. Public Water District #4 serves areas just outside.
This matters for rebates. PCEC’s weatherization rebate is tied to an energy audit by the co-op’s own Energy Use Specialist, which happens before any improvements are made. If PCEC is your electric provider, we’ll go through those steps with you before scheduling. If you’re on Evergy, we check that program’s current Missouri terms instead. Gas works the same way: Spire and Liberty Utilities are separate companies, so check the name on your gas bill and we’ll look up what that utility currently offers before anything is promised.
From an 1843 County Seat to 2000s Subdivisions
Platte City was incorporated in 1843 on the south side of the Platte River. A Union squad razed the town, courthouse included, on December 16, 1861. The Platte County Fair, held each year just outside town, began in 1863. Today the town lies along I-29 and Highway 92.
- 1960s–1970s homes: ranches and split-levels with original insulation that has settled, uninsulated attic hatches, and gaps around flues and plumbing stacks.
- 2000s homes: larger two-stories where air leaks at knee walls, recessed lights and bonus rooms matter more than insulation depth.
- Older homes near downtown (about 12% predate 1950): thin or missing insulation, open wall cavities and possible vermiculite, which should be tested before anyone disturbs it.
Same Town, Different Fixes: A 1960s Ranch Next to a 2000s Two-Story
The ranch: one big, open attic over every room, usually easy to reach. The work tends to be straightforward. We seal the light boxes, wall tops and the flue chase, put in eave baffles, and add a deep, even layer of blown insulation. The biggest comfort change is usually in winter.
The two-story: a smaller attic over the second floor, plus sloped ceilings, knee walls and maybe a bonus room over the garage. Here, sealing the walls and floor of the bonus room and the open bays behind the knee walls often matters more than adding insulation depth. The biggest change is usually in how the upstairs feels in July.
In both houses the basement rim joist is worth checking. It’s a long, leaky seam that runs around the whole foundation, and spray foam closes it.
What Clients Around the Metro Have Written on Angi
“Luke and his team did an outstanding job with all of the above! Knowledgeable, professional and they did a great job cleaning up the work site. Everyone was very friendly and the estimate for the work was less than other companies. I will definitely be referring them to friends and family!”

“It was great. They came on time for the initial assessment and professional. The quote was made for the things that needed done. They came the following week to get those things done. The house is much warmer since we made the change.”

How a Platte City Project Runs
- Call (816) 301-4448 (press 1 to skip the intro) and tell us whether your electric bill comes from Evergy or PCEC.
- Testing visit: blower door, infrared camera and an attic inspection with photos. If you’re a PCEC member, we’ll explain how the co-op’s own audit requirement fits in.
- Written proposal: sealing is listed first, then insulation, then any rim-joist or crawl-space work.
- Work day: we cover floors, seal the attic floor, install baffles and blow in the insulation.
- Retest: a second blower-door reading shows the change.

Is my Platte City home on Spire or Liberty Utilities gas?
Inside city limits it’s most likely Liberty Utilities: the city’s Local Utilities page lists Liberty/Empire, and the Missouri PSC locator shows Empire District Gas for Platte City. The same locator lists Spire for many nearby Platte County towns, such as Parkville and Riverside. Your gas bill settles it, and it tells us which rebates to check.
Can a PCEC member get help paying for insulation?
PCEC offers a weatherization rebate, but it’s tied to an audit by the co-op’s own Energy Use Specialist, done before the work. Read PCEC’s current terms, or ask us to walk through them with you, before work begins.
Do you serve homes outside Platte City limits?
Yes. We work throughout Platte County, and our shop is at 6114 MO-9, Kansas City, MO 64152.
