Customer Testimonials

Maria T. — Anaheim Hills, Attic Insulation Upgrade

We had Thermal Nest come out to replace decades-old blown-in insulation in our Anaheim Hills home, and the difference was immediately noticeable. The crew showed up exactly when they said they would and walked me through every step before touching anything. They installed new blown-in fiberglass insulation and sealed several air gaps we didn’t even know existed. Our energy bill dropped noticeably within the first month. I couldn’t be happier and have already recommended them to two neighbors.

Derek and Susan P. — Platinum Triangle, New Construction Insulation

We hired Thermal Nest for spray foam insulation on our newly built condo near the Platinum Triangle area, and they exceeded every expectation. The team was professional, courteous, and incredibly detail-oriented throughout the entire project. They helped us understand the R-value requirements for our climate zone and recommended the most cost-effective solution for long-term savings. The finished work was flawless and passed inspection on the very first visit. We would not hesitate to call them again for any future project.

James L. — West Anaheim, Crawl Space Insulation

My older home in West Anaheim had no crawl space insulation at all, and the floors were cold every winter. Thermal Nest sent out a technician for a free assessment who gave me a clear, no-pressure quote the same day. The installation crew was efficient, respectful of my property, and cleaned up completely before leaving. The floors are noticeably warmer now and I feel like the whole house holds heat much better. Great value for the price and outstanding customer service from start to finish.

Angela R. — East Anaheim, Spray Foam Wall Insulation

After getting three quotes for spray foam insulation on my East Anaheim home, Thermal Nest stood out because they actually explained what they were doing and why. The other companies just handed me a number with no real context. The installation was done in one day and the crew was polite and tidy throughout. My home stays cooler in the summer now without the AC running as long, which is a huge win. I left a five-star review on Google and I meant every word of it.

Tom and Linda G. — Anaheim Colony Historic District, Batt Insulation Replacement

Renovating a historic home in the Colony District comes with a lot of unique challenges, and Thermal Nest handled them all with care and expertise. They were sensitive to the age of our walls and used the right batt insulation products that wouldn’t damage the original structure. The project manager kept us updated throughout and made sure we understood everything that was happening. Our home is quieter and more comfortable than it’s been in years. We’ll definitely be calling them again when we tackle the attic next year.

Kevin M. — Stadium District, Attic Air Sealing and Insulation

Thermal Nest did a full attic air sealing and insulation job for our place near the Stadium District and the results were fantastic. The technician found several spots where conditioned air was escaping that we had no idea about and addressed them all before installing the new insulation. The team worked quickly and left no mess behind whatsoever. My wife was especially impressed by how professional and friendly everyone was. Our home feels like a completely different place in the best possible way.

Rosa C. — South Anaheim, Insulation Removal and Replacement

I called Thermal Nest to remove old, damaged insulation from my South Anaheim home and replace it with a modern blown-in solution. The team handled the removal safely and thoroughly, taking care to protect the rest of my home during the process. They explained the differences between insulation types and helped me choose the option that made the most sense for my budget and my home’s needs. The new insulation has already made a difference in how cool the house stays on hot afternoons. I recommend Thermal Nest without any reservation at all.

Brian H. — East Anaheim Hills, Garage and Interior Wall Insulation

We had Thermal Nest insulate our garage and a few interior walls in our East Anaheim Hills home to help with both temperature and noise control. From the first phone call to the final walkthrough, every interaction was professional and clear. The crew was on time, worked cleanly, and finished faster than expected without cutting any corners. The noise reduction between rooms is remarkable and the garage stays so much cooler now. This company clearly takes pride in doing the job right the first time.
