Our experience with Foam Tek was top notch all of the way around. Ryan was out promptly to provide an estimate, which was exactly what we paid when the work was completed. Damon and Matt performed the work and the result is exactly as we hoped and expected it to be. Communication was great, everyone arrived when they said they would, and they cleaned up when they were done.

Foam-Tek came out to level driveway and sidewalk filling a large void under both. They were very responsive from start to finish. Great company to work with would highly recommend using them.

Foam-tek leveled our front steps. They had been total lop sided for over 30 some years. So we contacted Foam-Tek. The came gave us a free estimate which was reasonable. Plus they were able to get us on the calendar quickly. One of the many reasons that we loved working with Foam-Tek was that they stayed in communication with us the whole way through. When all of us were thrown a curve ball and we had a very unique set of steps but, that is a whole other story. Foam-Tek handled it even with this unique step situation. Foam-Tek Matt found and got the equipment to level our steps. Matt and his assistant were very friendly and were very efficient. In the end our front steps are level and looking fabulous.

Wonderful business and good culture. The owner Donna was very helpful and was kind enough to help a smaller non competing business with some suggestions about team building and operations. It says a lot about the integrity of an organization when the owner is willing to help other companies in the industry with regards to coaching and elevating the industry. - Mike Comfort 1st

Joe and his team foam insulated under the floor of our sun room, drilled and filled our garage walls, hung a vapor barrier on the garage ceiling and blew fiberglass insulation in the garage attic. They were easy to work with, returning multiple times to accommodate other steps in wiring and hanging wallboard. They also kept the work areas neat. Joe's pricing was reasonable and he went out of his way to help us complete our project. I commend Spray Foam tech.

Wonderful service from Joe and his Crew! Joe was responsive, friendly and professional. He came right away and gave a very fair quote to spray an unfinished room. I did some demo/removal of old insulation and when I realized there would be some complications Joe came out right away again to problem solve. He gave an incredibly reasonable revised estimate and there were no surprise costs once the job started. His crew were on time, respectful and committed to doing the job right. I will definitely call again for my next insulation job.

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.

jen lahren★★★★★2 months ago

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 had an outstanding experience with Metro Home Insulation. They insulated our home & garage 2 years ago. When going through the estimating process, we felt they had the most knowledge and the best approach. They completed the work on time and on budget. Our heating and cooling bills have been lowered dramatically. We were very pleased with their attention to detail and the end results.

Alan Bauer★★★★★a year ago

Excellent fast service! Metro Home installed a fireplace in our home, we needed service and Dave took care of us the next day. I highly recommend.

Laura Weis★★★★3 years ago

We used Metro Home to install a new fireplace we purchased with them. Mary, the fireplace rep, was a joy to work with as she was quick to reply via phone and email with any questions I had. The install crew was also great! Very knowledgeable and got the job done quickly. We love our fireplace and would definitely recommend Metro Home to anyone in the market for a fireplace at a competitive price.

Frequently Asked Questions — Spray Foam Insulation in Elk River

These are the questions Elk River 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 5 verified Elk River 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 Elk River, MN?▼
In Elk River, 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 Elk River costs $2,000–$6,000. Most Elk River 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 Elk River, MN?▼
When searching for a spray foam contractor in Elk River, 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 Elk River 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 Elk River 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.
