Used Advantage Foam for our basement remodel. Very impressed with their attention to detail and happy with the end result. They caulked double studs and can foamed for fire draft without being asked. Everything was clean when they left and noticeably warmer right away. Price was very competitive. Highly recommend.

Chris Monson★★★★★a year ago

Peter and his team did a great job. Peter stoped by my place 2 different times to answer questions before the job. His crew showed up on time and worked through lunch to get things done. 100% would recommend, so far my garage heater has yet to kick on to keep the temp above 50 degrees.

Evan, Tyler, and Rob did an excellent job for my project to dense pack insulation for my home. The entire experience was very good. Pricing was reasonable, assistance for rebates, scheduling, installation, and clean up.

Ron Ketcham★★★★★a month ago

We had Century Insulation insulate our garage prior to our installing a garage heater. Their price was very competitive and they even notified us that they had an opoening in their schedule and were able to compelte the job two weeks earlier than originally scheduled. The crew, Justin and Evan, were fantastic. They were very respectful of our property, worked quickly and cleaned up after they were done, leaving our garage and property immaculate! We can't recommend Century Insulation high enough! Thanks for a great job!

Seldom do I leave reviews because it takes a lot for us to feel obliged to share an experience at a high rating. That being said - the team at Century Insulation were incredible. We began inquiring on their insulation services as early as November 2021, and again in fall 2023 as we planned out how we wanted to renovate our upstairs, and lastly in 2024 debating if we would keep what we had and improve it, or completely remove and start from scratch. We were trying to decide between traditional fiberglass or taking the modern approach - closed cell spray foam. In 2025, we made the leap to proceed forward. We renovated our Attic space and it required a full demo and insulation project to bring our 1950s era home up to modern standards. Our R value prior was next to nothing - 2 inches of fiberglass from the 1950s or 60s that had degraded in our one and a half story home. Days were often spent being over 100 degrees in our attic. My wife and I were thoroughly impressed by the team’s attention to detail and authenticity to delivering value and quality. Now when we’re in our attic, it’s cooler than the downstairs which is an achievement in a one and a half story home. A handful of shoutouts to the crew: Crystal in the office went above and beyond in scheduling the team out and working with our project timetable. She also advocated for the offered rebates and helped us achieve a very positive outcome. Ryan was flexible and made several visits to quote us and answer any and all questions in a timely manner. He was flexible with our budget and helped us achieve a quote that fit with our project. Jesse as the business owner made himself available for all relevant concerns around permitting, HVAC questions, and how we could get the best bang for the buck being spent with the R-Value we were looking to achieve. He also helped us pass inspection and in speedy fashion adding a paint layer required by our city. I enjoyed working with each of them and their crew that came out. Century insulation is a down to earth group of folks looking to do business with good people. People want to buy from good people - and these are good people. I would gladly partner with them again on future projects and have gladly given their info to others we know. Give them a chance if you’re looking to do an insulation project, you’ll be happy you did.

Frequently Asked Questions — Spray Foam Insulation in Newport

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