Customer Testimonials

Maria T. — Wood Ranch, Attic Insulation Upgrade

We noticed our upstairs bedrooms were unbearably hot every summer, so we finally called Next Level Insulation for an attic assessment. The team arrived on time, explained exactly what was lacking in our current insulation, and gave us a written estimate the same day. The installation was completed in one morning with zero mess left behind. Our energy bills dropped noticeably the very next month, and we wish we had done this years ago.

David R. — Bridle Path, Spray Foam Insulation

I hired Next Level Insulation to spray foam my garage and the bonus room above it, which had always been the coldest space in the house during winter. The crew was incredibly knowledgeable and walked me through the entire process before starting work. They protected all my belongings and finished ahead of schedule. The difference in temperature regulation is night and day, and every neighbor who visits comments on how comfortable the room is now.

Jennifer L. — Simi Valley Central, New Construction Insulation

Next Level Insulation handled all the insulation for our home addition, and I couldn’t be more impressed with the entire experience. From the first phone call to the final walkthrough, the communication was outstanding — I always knew what was happening and when. The team worked seamlessly alongside our other contractors without causing any delays. The quality of the work passed inspection on the first visit, which speaks for itself.

Carlos M. — Knollwood Estates, Crawl Space Insulation

Our crawl space was a nightmare — drafty floors and moisture issues had been bothering us for two winters. A neighbor recommended Next Level Insulation, and the recommendation was spot on. They assessed the space thoroughly and recommended the right solution without trying to oversell me on anything. The crew was professional, respectful of our property, and finished the job cleanly. Our hardwood floors no longer feel cold in the morning, which has made a huge quality-of-life difference.

Susan K. — Oakridge Estates, Blown-In Insulation

I was skeptical about blown-in insulation after hearing mixed things, but the team at Next Level Insulation thoroughly explained why it was the best fit for our older home’s attic structure. They answered every question I had with patience and no pressure. The installation was quick, and they sealed everything up perfectly before leaving. I can honestly say my HVAC system runs far less often now, and my utility bills reflect that savings every single month.

Tom and Rachel B. — Berylwood, Full Home Re-Insulation

We purchased an older home in Berylwood that had outdated insulation throughout, and Next Level Insulation came in and transformed the comfort level of the entire house. The project was large, but the team managed it efficiently over two days with minimal disruption to our daily routine. Pricing was transparent from the start — what they quoted is exactly what we paid. We’ve already referred three friends, and all of them have had the same great experience we did.

Angela S. — Santa Susana Knolls, Attic Air Sealing and Insulation

Next Level Insulation did both air sealing and insulation in our attic, which had been losing conditioned air for years. The technician took the time to show me exactly where the gaps were before any work began, which gave me complete confidence in their diagnosis. The work was done neatly and professionally, and the results were immediately noticeable. Our home holds temperature so much better now, and the team’s attention to detail really set them apart from other contractors I interviewed.

Brian H. — Royal Industries Area, Insulation Removal and Replacement

After discovering old, contaminated insulation in our attic, I needed a company I could trust to handle removal and replacement safely. Next Level Insulation was upfront about the process, the timeline, and the cost with absolutely no hidden surprises. Their crew was professional and kept the work area contained throughout the entire project. I felt confident the job was done right, and the new insulation has made a measurable difference in how efficiently our home heats and cools.
