Spray Foam Insulation in Johnston
A lot of times, it’s the insulation causing the problem. Around Johnston, the weather’s all over the place , one day it’s freezing, next it’s hot — so regular insulation doesn’t always cut it.
That’s why we started using spray foam. At Precision Insulation & Coatings, we’ve been helping people make their homes more comfortable without blowing up their energy bills. Whether you’re tired of drafts, want the air inside to feel cleaner, or just want your place to feel better overall, we know what works around here—and we’re happy to help.
Why Spray Foam Insulation?
You know how air sneaks in through little cracks and gaps, making your house drafty or stuffy? Spray foam insulation pretty much stops that in its tracks. It spreads out and seals everything — even those tiny corners you’d never think about. That means less outside air, moisture, dust, and even noise getting in.
The benefits include:
- Bills that don’t make you flinch every season
- A house that doesn’t feel like a rollercoaster of hot and cold spots
- Less worry about damp walls or mold
- Insulation that just stays where it’s supposed to — no sinking or sagging
- Breathing cleaner air inside

Why Choose Precision Insulation & Coatings?

Concrete Leveling
Do you have uneven sidewalks or a sinking driveway? Our concrete leveling service is quick, efficient, and far more affordable than a complete replacement.

Fiberglass Insulation
If you’re looking for an economical option, fiberglass is ideal for attics and crawl spaces. It delivers solid performance and can complement spray foam insulation in key areas.

Atomic Suits
For industrial or agricultural buildings that require heavy-duty protection, we offer Atomic Suits—specialized coatings designed to withstand the toughest environments.

ROOF COATINGS
Our reflective coatings reduce roof temperatures in the summer, easing the strain on your cooling system and lowering electricity costs.

Waterproof Roof Coating
Protect your roof against Iowa’s heavy rain, snow, and sun. Our coatings extend roof life, stop leaks, and help your home stay weather-resistant.
