I hired Assured Insulation to improve the insulation and efficiency of my attic space. After the initial installation, I had concerns regarding portions of the airflow, baffle coverage, and overall quality control.
To their credit, Craig, the owner, personally reached out, listened carefully, and took the concerns seriously. The company agreed to return, install additional baffles and ventilation improvements, and review the work more thoroughly.
One thing I learned through this process is that homeowners should stay actively involved during insulation projects, especially in attic spaces where much of the work becomes covered quickly. Asking questions and reviewing the work before insulation is blown can make a significant difference in the final outcome.
No company is perfect, yet I appreciated the responsiveness, professionalism, and willingness to work toward a resolution. I still believe there is room for improvement in onsite verification and quality control, yet I do believe the owner made a sincere effort to address the concerns and improve the outcome.
I hired Assured Insulation to spray foam my garage attic. The goal was to better regulate the garage temperature and reduce noise from the garage door for a bedroom that shares a wall with the attic space. From the very first interaction, the experience was noticeably different from other contractors I've worked with.
The estimate: Josh came out to assess the job and was refreshingly honest. I had specifically requested a spray foam quote, but he gently tried to steer me toward cellulose insulation, explaining it would likely be overkill for my use case. He walked me through the different R-values, the pros and cons of each option for things like rodent control, and even made sure I understood the fumes involved with spray foam. Despite thinking it might be more than I needed, he respected my preference for a long-term solution and quoted both options so I could compare. That kind of honest, no-pressure guidance is exactly what you want from an estimator.
The overcharge: After the initial estimate, I went up into the attic and noticed that a second-floor bedroom extended into the attic space, meaning the attic square footage was smaller than the garage footprint Josh had used for his measurements. When I pointed this out, Josh came back, re-measured the attic, and calculated a fair refund for the difference. No pushback, no runaround. When I ultimately decided not to proceed with a second phase of work and asked for the $380 credit as a refund instead, they sent a check without hesitation. That says a lot about a company's integrity.
The install: The crew was efficient, professional, and neat. When they first assessed the attic, they identified that the soffits needed to be sealed before spraying and headed out to pick up materials on their own. While they were gone, I went up to take a look myself and realized that sealing those soffits could create a ventilation issue since they were essentially the only vents in the attic. When the crew returned and I shared my concern, they didn't get defensive about the wasted trip — they listened, agreed with my reasoning, and adjusted their approach. Before packing up their ladder and lights, they gave me the opportunity to inspect the finished work and sign off on it. Small gesture, but it made me feel like a valued customer rather than just the next job on the list.
The results: The garage temperature is noticeably better regulated, and the bedroom that extends into the attic space is significantly quieter — we can now open and close the garage door without waking the person sleeping in that room, which alone was worth the investment. The spray foam application looks good overall, though it appears they foamed over some debris on the attic floor that could have been swept up first.
The real star of the show: Lindsey in the office deserves special recognition. Every time I called, she knew me by name. She was kind, professional, and incredibly patient as I went back and forth between options and asked countless questions about pricing. The quoting process involved multiple revisions and estimate changes over the course of several weeks, and she never made me feel like I was being difficult. That level of personal customer service is rare and made the entire experience feel like I was working with a small team that genuinely cares.
Bottom line: This is a company that does honest work at fair prices and treats customers the way you'd hope every contractor would. Would absolutely hire them again.

Thanks so much for giving us a five star review! We strive for excellence and are glad to hear that you are a satisfied customer. Thanks for choosing us for your insulation needs!
They added more insulation to my attic that was in desperate need. The team arrived around 45 minutes late, but the office did call me that morning to let me know they were running behind, which I appreciated (not everyone does that). The men finished a lot quicker than I expected and shared pictures with me after the work was completed. So, overall I'm happy with their service and would use them again if needed.

The guys actually stapled the baffles to the roof boards before adding the blown-in insulation. They did a great job and cleaned the area. The team was friendly and answered all my questions!

We had them come do the for both crawlspace encapsulation and adding attic insulation. After looking, they said we were good on the attic insulation. They came and did the encapsulation and were here on time, efficient, and communicated well. Would recommend for your needs.

Assured did an assessment on my home as part of Ameren's energy efficiency program. It was set for September 16th, between ten and eleven A.M. I was already impressed because it wasn't some crazy 4-6 hour window!
Josh arrived on time, was polite and professional, and was done in about ten minutes. He was knowledgeable and even pointed out some spots in my ceiling that I hadn't noticed. We shot the breeze for a moment before he left, and I could tell he was a stand up guy. Loved his American flag tattoo, too!
And the lady that runs the place, Tracy I think, was very friendly when scheduling the assessment, too. She even knew my neighbors from church! I'll be going to Assured first for any work I need done on my home, and I'll be recommending my family and friends do the same.

Thank you for the 5 star review, such kind words and recommendations! We appreciate it so much.
Do not hire. They are very messy with spray foaming and leave you the clean-up. They are not experienced. I also hired them to clear old insulation out of my attic. Check their work because they are very dishonest. I had to call them back twice to finish cleaning out my attic and they still didn't get it done right. Each time they said it's all cleaned out. Don't trust them! They wasted my time and money. Don't make the same mistake that I did by hiring them.

David and Matt did an excellent job on my building! They asked great questions to level set what I was doing with the building. They nailed the installation of the foam and the clean up was awesome as well. I also appreciated the great communication with Trish.

Assured Insulation placed a vapor barrier and spray foam insulation on the walls of my crawl space. The work was done on time and on budget. I would recommend Assured Insulation.
