Customer Testimonials
Maria G. — Ramona Boulevard Area, Attic Insulation Replacement
We had old, compressed fiberglass insulation in our attic that was doing absolutely nothing for us during the summer heat. Next Level Insulation came out, gave us a thorough inspection, and explained exactly what we needed without any pressure. The crew was professional, fast, and left the attic and the rest of our home completely clean. Our electricity bill dropped noticeably the very next month — we could not be more satisfied with the results.
James T. — North El Monte, Spray Foam Insulation
I had several contractors look at my crawl space before calling Next Level Insulation of El Monte, and they were the only ones who gave me a straightforward, itemized quote. The spray foam installation was completed in one day, and the difference in drafts and noise was immediate. The technicians were courteous and kept everything protected while they worked. I would recommend them to every homeowner in the area without hesitation.
Sandra L. — Tyler Avenue Neighborhood, New Construction Insulation
We hired Next Level Insulation for the insulation work on our home addition, and they coordinated perfectly with our general contractor. Scheduling was easy and they showed up exactly when they said they would, which is rare in my experience. The blown-in insulation they installed in the new walls is already making a huge difference in temperature control. I appreciated that they walked me through every product choice and why it was the right fit for our project.
Robert M. — El Monte Historic District, Wall Insulation Upgrade
Our 1950s home had virtually no wall insulation, and summers were miserable. Next Level Insulation found a way to add blown-in insulation through small holes in the drywall, minimizing damage to our home’s original interior. The patches they made were smooth and the entire process was cleaner than I expected. Our HVAC system is no longer running constantly, and our home finally feels comfortable year-round.
Tina and Carlos R. — South El Monte, Radiant Barrier Installation
After getting several quotes, we chose Next Level Insulation because they were honest about what a radiant barrier could and could not do for our home — no overselling. Installation was quick and the crew was respectful of our space and our schedule. Within a few weeks we noticed our upstairs rooms were significantly cooler in the afternoon. We have already told our neighbors about them and two families on our street have since called for their own estimates.
Kevin A. — Cogswell Road Area, Garage and Interior Insulation
I wanted to convert part of my garage into a home office, and proper insulation was the first priority. Next Level Insulation helped me select the right combination of materials for sound reduction and temperature control. The installation was neat and the crew answered every question I had throughout the day. The finished space is quiet, comfortable, and everything I hoped for — well worth every dollar.
Angela P. — Ferris Avenue Corridor, Blown-In Attic Insulation
I was dealing with uneven temperatures throughout the house and sky-high summer cooling bills before contacting Next Level Insulation. Their team did a full attic inspection and identified several areas where we were losing conditioned air. The blown-in installation was completed in just a few hours and the crew cleaned up every trace of material before leaving. My home is dramatically more comfortable and my energy costs have come down significantly since the work was done.
David N. — Garvey Avenue District, Full Home Insulation Audit and Upgrade
Next Level Insulation did a comprehensive audit of our entire home and prioritized the work so we could phase the investment over time. They were honest about what was urgent and what could wait, which I deeply respected. When we did the full upgrade, the work was done on schedule and exactly on budget. The team communicated every step of the way and the final results speak for themselves — our home feels like a completely different house.

Across more than 100 reviews and years of service in El Monte, certain themes emerge again and again in what homeowners say about working with us. These are not talking points — they are patterns pulled directly from customer feedback:
Questions About Our Work and Reputation
How can I verify that your reviews are genuine?
Our reviews are posted on open third-party platforms including Google, Yelp, and the Better Business Bureau, where they cannot be edited or selectively removed by our company. Each review is tied to a verified account, and many include specific project details, neighborhood references, and follow-up comments. We encourage every prospective customer to read our full review histories on each platform before making a decision.
What does your workmanship warranty cover?
Our workmanship warranty covers installation defects and performance issues directly related to how the insulation was applied. This is separate from any manufacturer warranty that applies to the materials themselves. If you experience a problem with settling, gaps, or coverage inconsistencies after our work is complete, contact us and we will schedule a return visit to evaluate and correct the issue at no additional charge within the warranty period.
What happens if I am not satisfied with the results?
Customer satisfaction is the standard we hold ourselves to on every project. If you have a concern about your installation, call us directly at (626) 469-7656 and we will schedule a follow-up inspection as quickly as possible. We investigate every concern thoroughly and work with the homeowner to reach a resolution that addresses the issue completely. Our review record reflects a consistent pattern of following through when customers reach out.
How do I verify your licensing and insurance in California?
Next Level Insulation of El Monte operates as a fully licensed contractor in the state of California. You can verify our license number through the California Contractors State License Board website by searching our company name or license number, which we are happy to provide upon request. We also carry full liability insurance and workers’ compensation coverage, protecting both our crew and your property throughout every project.
Do you offer a satisfaction guarantee on your insulation services?
Yes. We stand behind every project we complete in El Monte with a satisfaction guarantee tied to both workmanship and professional conduct. If the installation does not meet the specifications outlined in your project agreement, we will return to correct it. Our goal is not simply to finish a job — it is to earn the kind of review that our existing customers have already left for us across every major platform.
Can I speak with a past customer before hiring you?
While we respect the privacy of our past customers and do not share contact information without permission, we encourage you to reach out to reviewers directly through Google or Yelp if their profiles allow it.
