Precision Insulation and Coatings did a great job with spray foam insulation in our Des Moines home. Scott Todd made the whole process feel natural and easy, and the results are fantastic. Highly recommend!

Chad Martin★★★★★5 months ago

I had the absolute pleasure of meeting Todd and his family! He helped us every step of the way to fully insulate our horse barn! We needed a solution to keep our horses cool in the summer and warm in the winter. Todd walked us through step by step from cleaning instructions to paint. We couldn’t be happier with his service and expertise. Give him a call for all of your insulation needs!

I've had AFI out twice to my home. They've blown insulation into 2 separate attics, used an open-cell foam on a master bedroom tray ceiling and closed-cell foam in a shared wall for sound purposes, by drilling down into the wall plate from the attic and filling the wall cavities. Both experiences were very positive--professional crew, courteous, clean operation, timely...the list could go on. They were incredibly responsive, and I found the value of pricing to be great. On top of that--it has shown a utility savings from historical comparisons and has led to a more comfortable and quiet home. We're in a 15-year old house that had what was deemed "adequate" insulation--so adding more won't hurt anyone, and you can't go wrong working with AFI. Thanks to Kane and his team for another good job.

Great job!!! They had to remove part of our siding to blow insulation into our outside walls and put it back. No one would ever know the siding was ever disturbed! Very reasonably priced, professional and friendly. They were respectful of our property and cleaned up well after themselves. Mike and Keven were great to work with! I would highly recommend this company.

We used AFI for our 2700 barn restoration project. Darren and his team were great to work with. Excellent quality work, safe work habits, fair price, and great attention to detail. I’ve used AFI twice in the last three years, and will use them again when I have the need. I highly recommend Darren and his team at AFI.

I called in looking for help with a project for my home and I had to say that Janelle was the epitome of class and professionalism helping out this little old lady who knows diddly squat about insulation and remodeling. She listened to me and helped me with terms she was as sweet as an Iowa cob of sweet corn. She got me to a salesman named Jr who was also very good. Thank you both.

Frequently Asked Questions — Spray Foam Insulation in Ames

These are the questions Ames homeowners ask most about spray foam cost, R-value, and open- vs. closed-cell foam — with context for local pricing and roughly 35% typical energy savings. Compare the 5 verified Ames contractors above for exact quotes.

How much can spray foam insulation save on heating and cooling bills in Ames?▼
Homeowners in mixed climates like Ames, IA typically see 20–30% reductions in total energy costs after spray foam installation. The savings come from both reduced heating in winter and reduced cooling in summer. The exact savings depend on your home's current insulation, size, and local energy rates, but most homeowners recoup the investment within 3–6 years.
Is spray foam better than fiberglass insulation for homes in Ames?▼
For most homes in Ames, IA, spray foam outperforms fiberglass significantly. Fiberglass batts insulate but do not air seal — meaning conditioned air still escapes through gaps. Spray foam both insulates and creates an airtight seal, addressing the root cause of energy loss. While spray foam costs more upfront, the performance difference in mixed climates makes it the better long-term investment for most homeowners.
Is spray foam insulation worth the cost?▼
For most homeowners, yes. Spray foam creates an air-tight seal that traditional insulation cannot match, reducing energy bills by 15–35% annually. It also adds structural rigidity, acts as a moisture and vapor barrier, reduces outside noise, and can increase home resale value. The higher upfront cost compared to fiberglass is typically recovered within 3–7 years. One important note: because spray foam creates a very tight building envelope, proper mechanical ventilation is important to maintain healthy indoor air quality and prevent interior moisture buildup. This is typically handled by an Energy Recovery Ventilator (ERV) — a system that brings fresh outside air in while pushing stale air out, recovering the energy from the outgoing air so you don't waste what you paid to heat or cool — or a Heat Recovery Ventilator (HRV), which works similarly but is optimized for cold climates. A qualified contractor will assess whether your home needs ventilation upgrades as part of the installation.
How much does spray foam insulation cost in Ames, IA?▼
In Ames, IA and the surrounding area, spray foam insulation typically costs $1.00–$3.00 per square foot installed, depending on the type and your home's specifics. Open-cell foam runs $0.44–$0.65 per board foot, while closed-cell foam costs $1.00–$2.00 per board foot. A typical 2,000 sq ft home attic in Ames costs $2,000–$6,000. Most Ames homeowners recoup this investment within 3–7 years through energy savings of 15–35% annually.
What is the difference between open-cell and closed-cell spray foam?▼
Open-cell spray foam is softer, less dense, and less expensive. It expands significantly and is ideal for interior walls, attics, and soundproofing. Closed-cell spray foam is denser, stronger, and provides a moisture barrier — making it better for exterior applications, crawl spaces, and areas prone to flooding or humidity. Closed-cell also has a higher R-value per inch (R-6 to R-7 vs R-3.5 to R-4 for open-cell). One key difference: open-cell foam allows some vapor movement, while closed-cell acts as a vapor barrier — an important consideration for your home's ventilation needs.
How long does spray foam insulation last?▼
Spray foam insulation is one of the most durable insulation options available, with a lifespan of 80+ years when properly installed. Unlike fiberglass batting which can sag and settle over time, spray foam maintains its shape and insulating properties indefinitely. It will typically outlast the building it is installed in.
How do I find a qualified spray foam insulation contractor in Ames, IA?▼
When searching for a spray foam contractor in Ames, IA, look for ones who are licensed, insured, and have verifiable reviews. Spray foam requires specialized equipment and training — improper installation can cause off-gassing, adhesion failure, or fire hazards. Ask for references, verify their insurance, and get at least 2–3 quotes. A qualified Ames contractor will also assess your home's ventilation needs — a tightly sealed spray foam installation requires adequate mechanical ventilation to prevent moisture and indoor air quality issues. FoamMatch pre-screens all listed contractors in Ames for licensing and insurance so you can compare verified professionals in your area.
How long does spray foam installation take?▼
Most residential spray foam jobs take 1–2 days depending on the size of the area. A standard attic takes 4–8 hours. After spraying, the foam cures within 24 hours, though most contractors recommend waiting 24–72 hours before occupying the space due to off-gassing during the curing process.
Does spray foam insulation need to be replaced?▼
No — spray foam insulation does not need to be replaced under normal circumstances. Unlike fiberglass insulation which degrades over time, spray foam maintains its R-value and air sealing properties for the life of the building. The only reasons to remove or replace spray foam are water damage, renovation work, or improper original installation.
