Spray Foam Insulation in Johnston, IA
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

Quick, clean, professional work and reasonably priced! I am so glad he was recommended to mePosted on Google Jennifer WhiteTrustindex verifies that the original source of the review is Google. My husband and I moved into a new construction home on November 1st. We were not part of the building process; it was a quick move. We realized shortly after moving in that the garage was not insulated. I made some contacts with various insulation companies and Scott Todd was the only one that got back with me and assured me he could get the job done in a couple weeks. Scott stuck to his promise and did a great job. What stands out in my mind the most was how polite, honest and hard working Scott is. I’d definitely recommend his service for your insulation needs.Posted on Google Andrew OswaldTrustindex verifies that the original source of the review is Google. Scott was great to work with! The came and insulated my shop's attic space and it's done a great job retaining heat!Posted on Google Max MorrisTrustindex verifies that the original source of the review is Google.

We are more than satisfied with his work, and would happily recommend him to others.Posted on Google Gregg GossTrustindex verifies that the original source of the review is Google. I discovered Precision while scrolling through FB. I’m very happy that I did. Scott arrived at my home within hours- not days, to discuss our insulation project. He provided me with some thoughtful education and advice prior to my decision. In the end, they did a great job and I would gladly use Precision again and highly recommend.Posted on Google Tanner LynchTrustindex verifies that the original source of the review is Google. Very knowledgeable and seems really passionate about what he does.Posted on Google Mike HughesTrustindex verifies that the original source of the review is Google. We wanted our garage to maintain a decent temperature during the winters and realized our ceiling was not insulated and heat was escaping as it was onlydrywall screwed into the rafters. Scott, the owner over and gave us several options as how to make it hold the heat in the garage along withadding some more structural stability to the rafters. Here are the options he gave us 1. R49 blown fiberglass 2. Spay foam 2" closed cell foam 3.. Both 1 & 2 blown fiberglass over the cell foam What I really liked about these options is how he said Why don't we start with one and go with the closed cell foam first. Let's see how that works and if you're satisfied we won't need to do anything else. If it's still not holding the heat you want then could come back and put some blown-in fiberglass on top. So far the heater that's set in the garage is set at 50° and it runs 5 minutes every hour where it used to run 5 minutes every 15 minutes in an hour. Note: before we had the insulation installed We also installed green hinges on our garage doors that make our doors air tight because they're spring-loaded. I would highly recommend Scott and Precision insulation and heating if you're looking for an honest, responsive owner who won't oversell you and is reasonably priced and extremely professional. Here are a few pictures of before and after.Posted on Google Cory RiglerTrustindex verifies that the original source of the review is Google. Scott and his crew did an amazing job insulating our attic and the area above our garage using spray foam and blown-in fiberglass. We had plumbing above the garage that would slow down on extremely cold days, along with a few cold spots in the ceiling caused by gaps from poor original installation by the home builder. Since the work was done, those issues are completely resolved. The difference is noticeable, and we honestly wish we had done this sooner. I would highly recommend Scott and his company to anyone looking for high-quality insulation work.Posted on Google Kenneth KingTrustindex verifies that the original source of the review is Google. I had Precision Insulation out to inspect my attic and evaluate temperature issues in my home. Their technician was extremely knowledgeable, thorough, and honest. He used thermal imaging to show exactly where heat loss was occurring and explained everything in a clear, straightforward way that actually made sense. What I appreciated most is that he didn’t try to upsell anything or push unnecessary work. His recommendations were practical and realistic for my situation, and the findings aligned perfectly with what I was experiencing in my home. It’s rare to find a contractor who takes the time to educate you, answers every question, and is genuinely focused on what’s best for the homeowner. Highly recommend Precision for insulation evaluations and honest expertise. I felt confident and informed after the inspection, which is exactly what you want when dealing with home performance issues.Posted on Google Brian SchwartzTrustindex verifies that the original source of the review is Google. Scott was superb on our project. He stayed on budget with high quality work. Appreciate his craft and communication with me through the process.
