Thermal Nest Insulation of San Diego helped me apply for a local rebate and I got money back.

Made a noticeable difference in our home's comfort right away.

I called Thermal Nest Insulation for a second opinion after another company quoted me an astronomical price for spray foam. The estimator was refreshingly honest and explained that for my home and San Diego's climate, high-density fiberglass batts would perform almost as well at half the cost. He showed me comparable R-values and let me make an informed decision without pressure. I saved over a thousand dollars and got excellent results. Integrity like this is rare.

I was skeptical about whether new insulation would justify the cost. Thermal Nest Insulation proved me wrong. They installed radiant barrier in our attic and added blown-in insulation on top of the existing material. Our second floor, previously unusable on hot afternoons, is now perfectly comfortable. The attic temperature dropped significantly immediately. The crew was efficient, respectful, and the price was substantially lower than two other quotes.

I manage several rental properties in San Diego and have used Thermal Nest Insulation for multiple attic projects this year. Every job has been handled with the same professionalism. Their office coordinates seamlessly with my tenants, crews show up when promised, and the work is always clean and thorough. Detailed invoices make tracking costs simple. Rare to find contractors this reliable. They've earned my ongoing business.

We added a sunroom last year and despite having insulation during construction, the room was always either freezing or blazing hot. Thermal Nest Insulation came out, inspected the existing work, and discovered large gaps where insulation had been improperly fitted around roof rafters. They corrected the issues, added material where needed, and sealed everything properly. The room is now comfortable year-round. Very fair charge for a small diagnostic job.

We purchased a 1970s home in Normal Heights and the original insulation was completely inadequate. Thermal Nest Insulation came highly recommended and delivered. The estimator spent time answering all our questions patiently and didn't push the most expensive option. The crew wore shoe covers, worked carefully around our attic storage, and even helped move a few boxes. The temperature stability throughout our home has improved dramatically and our heating bill was noticeably lower this winter.

I don't usually write reviews this detailed but Thermal Nest Insulation of San Diego genuinely exceeded my expectations. From the easy online booking to the clear estimate, punctual arrival, methodical workmanship, immaculate cleanup, and follow-up call—every step was professional. Our home has never been more comfortable and our energy bills are already trending downward. This is exactly the kind of local business I want to support and recommend to friends and family. Five stars without hesitat
