Just for clarity, I've never used Marshland Spray Foam's services. That said, I was calling around the area to get some insulation work done and while Marshland didn't offer the services I needed, they actually took the time to connect me with someone who did and I was able to get my job completed in a timely fashion. In a day and age when it is usually just a "We don't do that *Click*", the fact that I was so well treated even though they weren't going to make a dime off me, says a lot about the level of service and care they wish to provide!

John Cimermancic★★★★★a year ago

Insulated my 30x40 garage and could not be happier. The price, the prep work, the communication, the cleanup, and last but not least the end result were all top notch. You can't go wrong with Marshland. The guy doing the quotes, Neal, is also the person doing the work with a small crew so there aren't any surprises and he was great to work with.

When we moved into our place in Milwaukee, we knew the insulation was bad but didn’t realize how much it was costing us until that first winter hit. A coworker told me about Seal Tight Spray Foam, so I gave them a call. They came out, did a full inspection, and explained where we were losing heat and how spray foam could help. The crew was super professional and took care of everything in just one day. Since then, the house has stayed way warmer and our energy bills have been way lower. Honestly one of the best home upgrades we’ve made. Huge thanks to the Seal Tight team for taking care of us.

Rythm Huddleston★★★★★a year ago

The whole process with Thermal Comfort has been great. Dason was the only person to actually come out and look at my remodel before quoting the spray foaming out of several other quotes I got. Then the day came and the team came. They did a great job, and it was not a simple job. It was a remodel with a bunch of harder to spray areas. They got in as many nooks and crannies as they could. I am very happy with the work done.

Jk Power Systems★★★★★5 years ago

We have been in a 2 year long build with many facets. I reached out to Dason at the very beginning about the project and his professional insight was spot on. I had very specific engineering requirements for our build to achieve a very high performance, Thermal comfort gave us what I required. I had a previous Spray foam contractor from a prior build and received 3 additional bids for this 2020 project. I choose Thermal comfort from the 4 companies for several reasons and I am very pleased that I did. Closed cell IMO is the only way to go, that said the install is critical and the site crew was fantastic. George, was the lead and listened to my install concerns and did an excellent job. Rich and Walt were also on hand and also did great. They accommodated us the best possible in the timing of our project. They were thorough, conscientious and and their site prep and clean up was excellent. We have future projects and they will be our insulation contractor from now on.

Aaron Wilson★★★★★5 years ago

If you’re looking for a spray foam guy, look no more. Dason and his team are outstanding! Very flexible schedule wise and very competitive pricing wise. I will be using Thermal Comfort for all my future spray jobs. Highly recommend!

Intec came recommended to me through a Reddit post asking about insulation companies and peoples recommendations. I had my attic insulated, bathroom exhaust fan installed, and a rim seal done in my basement. The difference was noticeable right away with the furnace not running nearly as often and the heat staying in. I sent the quotes and photos of the work done to my friend in Missouri who owns their own insulation company and they were thoroughly impressed with the work and agreed with all the recommendations! Today, Focus On Energy, which is a group that verifies the standard of insulation meet quality parameters inspected the work done and passed the work with flying colors! The work itself was done in 1 day for my 700 sqft home and the office worked with me through a financial plan that made sense. Overall, I can’t recommend them enough as a first time home-buyer!

Dave Purcell★★★★★2 months ago

Intec insulated the second floor of our Cape Cod and sealed off areas where air was leaking. Eric was terrific to work with in learning about our needs and giving an estimate and follow-up explanations. The office staff were helpful in scheduling, and the onsite work team were professional and friendly. Terrific work all around!

George Hamzik★★★★★2 months ago

I was not sure of the impact that getting my attic re-insulated and my upstairs sealed up was going to have this winter. After going through this recent cold spell I can say it was well worth it. I have an older house and the work they did helped hold in the heat extremely well even when temperatures were below zero for a few days. The project manager who came out for the initial consult walked me through everything they proposed and how it was beneficial from either a heating or cooling standpoint. The estimate provided was detailed out and easy to understand. The team that came out to do the work was prompt and professional. Everything in my house was protected before they started and cleaned up before they left. If I ever have insulation needs again INTEC will be #1 on my call list.

We are very impressed with the quality of their work and the professionalism of the crew. They were on our property 4 days, were minimally intrusive and cleaned up every day before leaving! We already feel the effects of better insulation in our 1929 bungalow.

Steve Steinhaus★★★★★9 months ago

Crew did great work, laid down plastic and drop cloths to protect my furniture and floors, they were even mindful of my cat making sure he didn’t try to escape out the front door. Very satisfied with the quality of the job. Due to the way my old house was built, a portion of the job was physically impossible to execute. Shiela immediately updated my invoice to reflect that. No complaints!

Amy★★★★★a year ago

S & E did our attic & knee wall insulation back in Dec 2023. We’ve had their work inspected twice by Focus on Energy, and the inspector said they did an excellent, thorough job, and our attic is now completely dry and mold-free! After decades of problems with this, it is finally resolved, thanks to S & E. Great job, guys!

The crew they sent were fantastic. They really took pride in your home and the interior and exterior very polite very knowledgeable. They walked you through everything. It was a pleasure to do business with them outstanding and not to write a review, but these people did deserve it.

Mary Bacovsky★★★★★a month ago

I had three quotes done for my attic basement and crawlspace. I also had my old Insulation extracted. I chose USA Insulation because that’s all their company does and it soon became apparent that in this case, this was important. From my first contact with the office I was greeted with a pleasant knowledgeable employee. Well done Lexi. Mike did the estimate. He was very thorough and I had my itemized quote done before he left. I did not feel pressured. USA Insulation is also well versed with energy rebates. I was anxious about the process so I asked a lot of questions. Emily was accessible and reassuring throughout the process. The work took two days and each morning I was greeted by the foreman that explained the day’s event. All workers were considerate and respectful of my home and my comfort. (The install was on the coldest days of the year.) I was fortunate to have access to my attic from my garage so I hardly knew they were there. When they were done it was like they were never there. Every mess was cleaned up. It’s important to know that if you have foam insulation done, (which as a toxic odor), you don’t have to be concerned because they ventilate during the insulation. This is not the case with some other contractors. My post energy blow test is yet to be scheduled, but I’m hoping I see a significant difference in numbers, especially since I had very little insulation in my attic.

Ben Schlehlein★★★★★a month ago

Parker and his crew did an awesome job despite our siding (and the cold) kicking their butts! We already are feeling an improvement both in temperature and sound dampening from the outside. They were prompt and cleaned up just as good if not better than before. HIGHLY recommend having your house insulated by Parker and the crew!

Tony and his crew did a thorough and professional job insulating the attic. The work was completed cleanly and to a high standard. He responded promptly, proposed a comprehensive long-term solution, and did not attempt to upsell unnecessary services. Pricing was fair and transparent.

Tim Joost★★★★★2 years ago

I had Tony bring my insulation up to current recommended spec. He was very prompt to respond to my initial inquiry and explained what he does and his experience. Once he came out he gave me detail on what was needed and had a quote back to me the next day. His pricing was very competitive and we were able to get the job on the books immediately. He also was able to get me scheduled quickly due to a change in his schedule and worked with my needs. Him and his team made quick work of the job and made sure I understood what they did. He covered everything with tarps and cleaned up prior to leaving. I would recommend Whole House Insulation to anyone considering using them.

Uliana Heron★★★★★10 months ago

Tony gave us a fair quote and did work within a week. Our house feels a lot warmer now. We will definitely hire Whole House Insulation again for future projects

Frequently Asked Questions — Spray Foam Insulation in Milwaukee

These are the questions Milwaukee homeowners ask most about spray foam cost, R-value, and open- vs. closed-cell foam — with context for local pricing and roughly 37% typical energy savings. Compare the 10 verified Milwaukee contractors above for exact quotes.

Why is spray foam insulation especially important in cold climates like Milwaukee?
In cold climates like Milwaukee, 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 Milwaukee?
Yes — spray foam insulation is one of the most effective solutions for preventing ice dams in cold climates like Milwaukee, 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 Milwaukee?
For cold climates like Milwaukee, 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 in Milwaukee, WI?
In Milwaukee, WI 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 Milwaukee costs $2,000–$6,000. Most Milwaukee 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 Milwaukee, WI?
When searching for a spray foam contractor in Milwaukee, WI, 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 Milwaukee 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 Milwaukee 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.
