They re-insulated our crawl space under our dining room. From the appointment with Jon to getting an estimate and Uriah and his team to install was smooth and seamless. Jon was very responsive and answered any questions we had quickly. He also provided options for the work if cost was a concern. We felt their price was fair and reasonable and proceeded with the full crawl space. Uriah and one other came to install the insulation. I didn’t get his partners name, but they worked quickly and efficiently. Finished everything in a couple of hours and there was virtually no mess left. We had concerns about the dust that might be created by removing the old insulation, but they sealed the opening and there was no dust at all. Bagged up all of the old insulation and sprayed the new. We would recommend Koala for any of your insulation needs! They are also one of the few insulation installers who do crawl spaces on top of everything else.

We needed whole house insulation and choosing Koala was the best decision we made. Blow-in from exterior holes, then a total clean out and reseal in the attic, and then the garage as it’s a tuck under. A lot of work but a fair price and excellent service. Recommend.

I like to think a company is best judged not by when everything goes perfectly, but when there are issues. Everyone makes mistakes, miscommunications occur - it's impossible to *always* create a perfect experience. How we choose to react to those instances speaks to our merit. Koala insulation came to re-insulate my attic. Before the job, they had told me we couldn't be present while spraying due to fume risk, but otherwise we should be fine. When they were finishing up for the day, one of them made a comment to my roommate that was slightly misconstrued about the safety of being there. I had assumed I would recieve a message from them when they finished foe the day - they had let me know theyd text me when the job was *done* done, which wouldn't be for another day. So suddenly I found myself with my roommate (very reasonably) worried it might not be safe to go inside, after hours when no one was working to clarify. Not gonna lie, I was *extremely* angry. Thankfully, their automated system caught that I had a sensitive concern, and forwarded it to the person in charge. He called me directly, answered all my questions in detail, and confirmed we were safe to go in. Just a miscommunication, and one he took extremely seriously given the nature of the comcern it caused. I cannot tell you how much I appreciate how seriously they took that concern, rather than brushing it off or getting back to me the next day. All in all, they did a phenomenal job and were professional, courteous, and way faster than I expected. Cannot reccomend them highly enough.

Frequently Asked Questions — Spray Foam Insulation in Roseville

Below are common questions Roseville, MN homeowners ask about spray foam insulation cost, types, and installation. For local pricing and to compare verified contractors in Roseville, browse the listings above.

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 Roseville, MN?
In Roseville, MN 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 Roseville costs $2,000–$6,000. Most Roseville 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 Roseville, MN?
When searching for a spray foam contractor in Roseville, MN, 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 Roseville 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 Roseville 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.
