Retro Green has been the best insulation company! Oren is amazing with his attention to detail and thorough inspection. He was able to find all the issues with the insulation in my house and quoted a reasonable price. Nick and Crew came out to install the foam insulation into my slanted ceilings and fix a bath fan. They were respectful and hard working. Nick showed pictures of their work afterwards. Overall, was the best experience I have had with any contractor. I have had many! Thank you for being a trustworthy company.

We hired Retrogreen Energy to complete a retro installation of foam insulation in our existing walls. We have an old house with orignal newspaper insulation that was just not cutting it to keep us warm in MN winters. The consultation and installation process went very smoothly. The company took care of the available rebate paperwork which was great The crew completing the installation was very professional and communicated well with me throughout the day. It took just over half a day to complete the work from arrival to completed cleanup. We have cedar shakes as siding, and after the installation, we could hardly tell the work had been done.

I had RetroGreen do the insulation in my attic and walls. I can already feel the difference with cooling and I have less humidity. The installation crew was top notch. All so professional, kind and informative. The cleanup job they did left my attic space and stairs cleaner than when they started. I couldn’t tell where they removed the siding for wall insulation. They were careful working around the garden and flower bed areas. Couldn’t tell they had been there! I would recommend this company for insulation. I am looking forward to lower heat bills this winter.

We called them last minute and they were able to accommodate the insulation for our remodel with a reasonable amount of money. Did not go over their estimate.

Frequently Asked Questions — Spray Foam Insulation in St. Cloud

These are the questions St. Cloud homeowners ask most about spray foam cost, R-value, and open- vs. closed-cell foam — with context for local pricing and roughly 40% typical energy savings. Compare the 3 verified St. Cloud contractors above for exact quotes.

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