How Abraham finds what's missing in a Johnston house
- 1
Wait for the right weather
An infrared camera reads best when it's very hot or very cold outside, so a thermal scan isn't part of every estimate. In midsummer or midwinter, it can be, and it's worth asking about if one room in your Johnston house never feels right.

Scan the walls and ceilings
The camera picks up missing insulation and air leaks without opening anything up.
- 3
Look at the attic floor
Pipes, flues and wall tops pass through the attic floor even in a house built in 2015. Those gaps get sealed before anything else, so warm, damp air from the house can't get through them.

Fix what turned up
Depending on the scan and the attic, that can mean topping the attic up to R-49 with cellulose, dense-packing a wall, or air sealing plus insulation over the garage.

From Johnston Station in 1905 to 24,000 people
Johnston started in 1905 as Johnston Station on the Des Moines & Central Iowa Railway and incorporated in 1969. It's home to the Camp Dodge military reservation, and it sits entirely in Polk County.
The town nearly tripled between 2000 and 2020, from 8,649 people to 24,064, and the housing shows it. The median home was built in 2004, about 6 in 10 date from 2000 or later, and only about 7 in 100 are older than 1980.
About 27 minutes from Des Moines

Before you book in Johnston
Our Johnston house was built in the 2000s. Could the attic have settled?
It could. Blown-in insulation settles, which is why Abraham accounts for it in the depth he installs. If the insulation went in when the house was new, it's worth checking whether it still reaches R-49.
Can the estimate be on a Saturday?
Saturday hours are 8:00 AM to noon, and weekday hours are Monday to Friday, 7:30 AM to 5:00 PM. Call or text to set a time that works.
Do I need a permit from Johnston for insulation work?
Abraham hasn't needed permits for insulation work in the towns he serves, Johnston included.
