Had Profoamers insulate ½ of basement’s upper box sills with closed cell spray insulation. I was able to handle everything on-line providing the job’s measurements and receiving back a quote. I felt it to be a very fair price. Insulators arrived on time, in fact early. Their truck was very clean and with all the equipment extremely organized. While showing them the scope of the project they stopped me often to ask detailed questions of my exact wishes of how I wanted each portion applied. The process did not take long and upon my inspection, I was pleased to notice everything was cleaned and the floors were swept spotless. It was evident they were pros at doing this and were very proud of the completed job. I would certainly call them in the future and recommend them to anybody that asks me.

Pro-Formers did a great job on my projected. They showed up early and finished on time. Nice job cleaning up after the job was done. I had not sealed some area like I should have, which resulted in some over spray. They kept a positive attitude and cleaned up my miss. Great team of guys. I will use them again.

Pro-Foamers is a great company! They did an amazing job on my basement! Sealed the outside concrete, spray foamed the basement walls inside. Kelly’s recommendations are spot on! They did the work very fast and cleaned up everything when finished. Would highly recommend them. Thank you Pro-Foamers!!

Dan and his workers were great do work with. Dan was very responsive and proactive. He returned my calls in a timely manner, showed up when he said he would, did quality work and had fair pricing. My project was a 900 sq. foot exterior building building and they blew insulation into the attic.

Tom is very thorough and down to earth. He came out, inspected and gave an estimate within a couple days of calling. The estimate was given on a Friday and by Monday afternoon he was here to do the job. The house was cleaned up perfectly afterwards. This company is top notch in my opinion! If you want a knowledgeable man at a very affordable rate look no farther.

Worked with Tom on adding insulation to my attic. Awesome guy to work with, provided excellent service and knowledge and did an amazing job! My A/C unit no longer runs 24/7 and it is 100x more quiet inside my home. Great price, great work, and great people. Definitely go with these guys if you need some insulation work!

When building our new modular home we decided to have a 32x32 attached garage built with an attic for storage with access from a typical stairway. Driving to and from our place we would see the Comfort Pro building from the highway. I did some checking and found good reviews on this very same google platform so I called. I was put in touch with Gary, who has since retired, and he was absolutely great to work with. He was timely in providing an estimate and was very honest about timing since this was at the height of covid. Gary indicated several times that it would happen on short notice, and it did indeed, but with Gary continually keeping in contact kept us at the ready by having electrical etc., completed. The applicator(s) were awesome having covered everything as well as working with a couple of other contractors on-site to move a few things around. Outside of foaming two sets of rolled up wires for outside lights (my fault) the job was perfect. We would definitely use them again. December 2023 Update: We used Comfort Pro once again to work on our Box Sills all around the basement. The two guys were on time and did an awesome job removing the Fiberglass Bat insulation then spraying the same foam insulation as we had installed in our garage. Again, I can't say enough about the two gentleman who came to do our project as well as Sean Capelle who provided the estimate and scheduled the work with us. Very accommodating. Thank You!!!

Great experience with Comfort Pro Insulators. Sean was quick to respond to my calls, met me at my cabin and we discussed that I was having an issue with the duct work under the house and the AC not working properly. His guys showed up on time and sprayed the whole underside of the cabin including the duct work. Twenty minutes after they finished, I turned on the AC and it now works like it should as they spray sealed all of the underside duct work!

Connor Chrisman★★★★★a week ago

Sean and the Comfort Pro team were great to work with for my insulation project. They were very thorough when walking through the different options for me in order to turn my exterior garage into a comfortable space in the summer/winter. Always easy to get ahold of for any questions I had during the process as well!

I called Dan at the recommendation of the Focus on Energy contact at my local utility. I own an apartment building built in 1880s and issues in old buildings can be complex and complicated by the myriad of material ages and fixes over the years. Dan is incredibly knowledgable and practical. An insulation and energy nerd, and I mean that as the biggest compliment I could give someone in the field. The solution he proposed fixed my issue and will help protect my building for the next 100 years. He explained everything to me in a manner where I felt informed. He does not oversell and you can trust that he will guide you to the best decision for your goal. While doing the work, he and his crew were exceptionally clean and professional from audit to last screw. I would not trust anyone else with insulation, home comfort or energy needs.

Kate LeMieux Espinosa★★★★★4 weeks ago

I highly recommend Dan and his team! We had a moisture issue and lack of insulation in the attic of our 70 yr old home. Dan provided a comprehensive solution at a fair price. His team was very polite and professional. update: We were still experiencing an issue that hadn’t been properly addressed by a previous contractor. Dan, the owner, came back to the house multiple times until the problem was fully resolved. That kind of dedication and integrity is hard to find. It gave us a lot of confidence knowing the owner was personally invested in getting it right. Highly recommend.

Jennifer Ellenbecker★★★★★4 months ago

Dan did an exceptional job explaining the necessity of proper attic insulation and the benefits it would provide to our family. He took time to point out what immediate needs were and how his team could address them effectively and efficiently. Dan and his crew are friendly, professional, and good around both dogs and kids! We appreciate their time, hardwork, and thoughtfulness. We will highly recommend Home Energy Solutions of Wisconsin to others! Thanks again! 🏡

Delivery Appt time 5am they opened overhead door at 4:30, I backed in, by 4:45 they were already unloading me. Yes I backed down driveway easy enough, and parked overnight to the side so others could get by me. Didn’t mind delivering to this place at all.

TRUCKERS: Don’t pull into lot. Turn left then back down the driveway half way and be sure to stay as far to one side as possible so their work trucks can get through. They had no problem with me parking here overnight. The dock will be the overhead door directly behind you if you backed down the driveway. Super friendly people and they unloaded me an hour before my appointment and I was gone in 20 minutes. My photo is from the vantage point of the dock. That’s the driveway you need to back down.

Frequently Asked Questions — Spray Foam Insulation in Green Bay

Why is spray foam insulation especially important in cold climates like Green Bay?
In cold climates like Green Bay, WI, proper insulation is critical to preventing heat loss, ice dams, and frozen pipes. Spray foam's air-sealing properties stop the cold air infiltration that traditional insulation cannot address. It also prevents the moisture buildup inside walls that leads to mold in cold-weather freeze-thaw cycles. Homeowners in WI typically save 25–35% on heating costs. Note: in tightly sealed homes, proper mechanical ventilation is commonly recommended to maintain fresh air exchange without losing the heat you've paid for.
Does spray foam insulation prevent ice dams in Green Bay?
Yes — spray foam insulation is one of the most effective solutions for preventing ice dams in cold climates like Green Bay, WI. Ice dams form when heat escapes through a poorly insulated attic, melting snow that refreezes at the eaves. By creating an air-tight thermal barrier in the attic, spray foam eliminates the heat loss that causes ice dams in the first place.
What R-value do I need for spray foam insulation in Green Bay?
For cold climates like Green Bay, WI, the Department of Energy recommends attic insulation of R-49 to R-60. Closed-cell spray foam provides R-6 to R-7 per inch, meaning 8–10 inches achieves code-minimum performance. Open-cell foam at R-3.5 per inch requires greater thickness. A local contractor familiar with WI building codes can recommend the exact specification for your home.
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?
Spray foam insulation typically costs $1.00–$3.00 per square foot installed, depending on the type and your location. 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 costs $2,000–$6,000. Most 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?
Look for contractors 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 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 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.
