Koala Insulation did an outstanding job on my home project. They added R-50 blown insulation to the attic over the garage, sealed the top plate between the garage and living area, and replaced the insulated duct to our master bath fan. The team was professional, efficient, and represented Koala Insulation exceptionally well. They completed everything in under two hours and left the area spotless. Highly recommend Koala Insulation for anyone looking for quality, reliable insulation work!

Everyone did a great job from consultation to install. Matt and John treated my home with respect and actually found a way to cut some cost for me while resolving my issue. If you need any attic/insulation work I would whole heartedly recommend Koala.

First, I’ll start off saying I was looking at reviews koala came up very well. So when I call them young man named Kayden came out and did a very good inspection he came back with his results. The results were a little worse than I was hoped for mainly because there were signs of potential mold starting up there, but he said everything could be handled. give me a detailed list itemized everything out. It’s a pretty good price, but it was a lot of work. I tried to get some other companies to give me an estimate off off of his inspection, but none of them would take that up. So we simply scheduled to work and a gentleman named Ryan and another coworker who I am sorry to say I don’t have his name came out. They were at the house pretty much at the time described little after seven got right to work and absolutely it was an all day job for sure they had to remove every bit of old insulation a sprayed all the wood that was looking black from potential mold. they had to put baffles in everywhere cause there were none and they had to go around and check every eve vent, and every one of them had to be enlarged. Some of that was due to the construction type of the house. I couldn’t be more satisfied with the workmanship with the two men who worked all day, a gentleman by the name of Matt 1 of five with the company I believe also came out. We discussed adding a ceiling exhaust fan in the bathroom which we had never had. We upgraded to a different one which was fine very nice man and Ryan suggested maybe we should call a roofer out. He had a friend that was in the business so we did that and that gentleman showed up another very nice young man with Shamrock roofing the roof is basically OK from the outside of the plywood was getting soft so next roof will have that fixed but overall I think the guys did a top notch job on a job that was probably not the easiest one they come across and I’m very very satisfied with what they did

Our experience with this company was nothing but positive. We were referred to this company when another contractor stood us up. We worked with Chad and he was prompt with responding to our request for a quote to re-insulate our attic and a space in our kitchen that was having issues.We received our quote within a week and the job was scheduled and done within another 2 weeks. The other companies we got quotes from wouldn't even address the issue in our kitchen. The insulators were here when they said they would be and the job was done in the timeframe they promised. Chad came by afterwards and inspected the work. From start to finish he was friendly and informative. We would recommend them to anyone needing insulation work done in a timely manner at a reasonable cost.

We had a great experience with Cornhusker Insulation. Chad was great to work with and was very educational and honest about bringing our insulation level in our attic up to standards. Also, the crew that performed the work was so quick and efficient! Would highly recommend!

Terrible to work with. After the estimate is prepared, you will never see that person again and the crew that shows up, if they show up, will have no background in your project. After two days of no-call, no-show they arrived 4 hours late. They left our house a complete mess and didn’t tell us they were leaving. They apparently don’t carry vacuums or even trash bags with them to clean up their mess. If you loan them one, expect it to be left in the middle of your living space and not carried outside. They even used our tools and never put them back. There are plenty of other insulation companies you should try before you call this one.

Frequently Asked Questions — Spray Foam Insulation in Waterloo

These are the questions Waterloo 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 2 verified Waterloo contractors above for exact quotes.

How much can spray foam insulation save on heating and cooling bills in Waterloo?▼
Homeowners in mixed climates like Waterloo, NE 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 Waterloo?▼
For most homes in Waterloo, NE, 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 Waterloo, NE?▼
In Waterloo, NE 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 Waterloo costs $2,000–$6,000. Most Waterloo 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 Waterloo, NE?▼
When searching for a spray foam contractor in Waterloo, NE, 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 Waterloo 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 Waterloo 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.
