Customer Testimonials
Marcus T. — Wood Ranch, Attic Insulation Upgrade
We had our attic insulation completely replaced by Thermal Nest last summer, and the difference in our energy bills was immediately noticeable. The crew arrived on time, protected our belongings, and left the space cleaner than they found it. The technician walked me through every step of the process and explained exactly what R-value we needed for our home in Wood Ranch. I would not hesitate to recommend them to anyone in Simi Valley looking for reliable insulation work.
Linda C. — Berylwood, Spray Foam Insulation
I called Thermal Nest after getting three quotes for spray foam insulation in my garage walls and crawl space. Their price was fair, their estimate was detailed, and there were no surprise charges when the bill came. The technicians were courteous and clearly knew what they were doing. Our garage is noticeably cooler in the summer heat now, which has made a huge difference for our family. Five stars without question.
Robert and Susan M. — Simi Valley Central, Blown-In Insulation
We bought an older home near the center of Simi Valley and knew the insulation needed updating. Thermal Nest sent an inspector who gave us a thorough assessment and recommended blown-in insulation for our existing walls — no major demo required. The installation was fast, tidy, and exactly as described in the quote. Our home stays much more comfortable during those hot valley summers, and we have already seen savings on our utility bills. Worth every penny.
Jenna P. — Oakridge Estates, New Construction Insulation
We used Thermal Nest for the insulation package on our new build in Oakridge Estates and could not be happier. They coordinated seamlessly with our general contractor and met every scheduling deadline without issue. The crew was professional and took the time to explain how each insulation type would benefit the different areas of our home. Our house passed inspection on the first try, and our HVAC system is running far more efficiently than we expected. Highly recommend for any new construction project in Simi Valley.
David H. — Bridle Path, Crawl Space Encapsulation
I was having moisture issues under my home in the Bridle Path neighborhood and Thermal Nest came highly recommended by my neighbor. They assessed the crawl space, identified the problem areas, and completed the encapsulation work in just two days. The crew was respectful of my property and communicated every step of the process clearly. Six months later, the moisture problem is gone and the floors above feel more comfortable. Outstanding service from start to finish.
Angela R. — Sinaloa Lake Area, Insulation Removal and Replacement
My older home had damaged insulation in the attic that was affecting our air quality. Thermal Nest handled the removal and full replacement professionally and quickly. They used proper containment procedures during the removal phase, which I really appreciated as a homeowner with young children. The new insulation has made a dramatic difference in air quality and temperature control throughout the house. I would use them again without hesitation and have already referred two of my neighbors.
Tom K. — Royal Aviation Park Area, Basement Wall Insulation
Thermal Nest insulated the basement walls of our home and the results have been fantastic. The team was punctual, courteous, and extremely knowledgeable about which insulation products would work best for our specific situation. They answered all my questions patiently and never made me feel rushed. The finished work looks great and the space is far more comfortable year-round. This is a company that truly takes pride in what they do.
Michelle O. — Erringer Road Neighborhood, Whole-Home Insulation Audit and Upgrade
After years of high energy bills, I finally called Thermal Nest for a full home insulation audit. They identified multiple areas where we were losing heated and cooled air and presented a prioritized plan that fit our budget. The upgrade was completed over two days with minimal disruption to our family. Our energy bills dropped significantly in the very first billing cycle. The team was professional, clean, and a genuine pleasure to work with from the first call to the final walkthrough.
