Highly recommend! Their customer service was A plus from the moment I contacted them for a bid throughout the entire process. I had only 2 weeks to get my business insulated & even with such short notice THEY MADE IT HAPPEN! I would definitely choose them for any insulation project I need from here on out. Thanks you guys!

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!
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.
These guys need a 6th STAR! Father & Son dynamic duos. I have meant many in the trades, this team is absolute top notch; Price / Quality / Service. Contact Neil ASAP for your spray foam needs - you WILL NOT be disappointed!

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.
For top-notch commercial insulation in Waukesha, WI, Seal Tight Spray Foam is a great choice. Their crew was efficient and handled the job with expertise. The insulation has made a big difference in our energy use and comfort level. Highly recommend their services!
I’m really impressed with the residential insulation work done by Seal Tight Spray Foam in Mequon, WI. The team was friendly, on time, and did a fantastic job. My home feels much warmer and I’ve noticed a drop in my energy costs. They really know their stuff!

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.
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.
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!
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!
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.
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!
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!

Very professional and courteous. As a contractor I have confidence in their abilities. Fyi Cheeto, 99.9999% of the time a subcontractor doesn't choose what time they start.
Great customer service and good work.

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.
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.
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.
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.
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
