What Our Customers Say

Hundreds of satisfied customers across Santa Ana and surrounding areas.

★★★★★

"Plastic laid from the front door to the attic hatch and they vacuumed the hallway afterward."

Danielle Hoffman
Danielle Hoffman Santa Ana, CA · July 2026
★★★★★

"Installed baffles at the soffits so the new insulation didn't block the ventilation, which the previous contractor apparently never considered."

Yolanda Martinez
Yolanda Martinez Santa Ana, CA · December 2025
★★★★★

"Spray foam in the rim joists in the basement. The cold floors above them are gone."

Nisha Sharma
Nisha Sharma Santa Ana Area · July 2026
★★★★★

"Told me the crawlspace didn't need doing and only the attic did. Half the job, half the money."

Ramon Herrera
Ramon Herrera Santa Ana, CA · May 2025
★★★★★

"He did a blower door test before and after and gave me the numbers. I like being able to see the difference rather than being told about it."

Sana Rao Santa Ana, CA · June 2025
★★★★☆

"Work is good and the house is noticeably more comfortable. There was insulation debris left in the hall closet under the attic access that I had to clean up."

Kristen Miller Santa Ana Area · April 2026
★★★★☆

"Solid job. It's hard to verify what's up there once they've gone, so I'd suggest asking for photos, which they did provide when I asked but didn't offer."

Neil Bennett Santa Ana, CA · February 2026
★★★★★

"Found and sealed a gap around the chimney chase that was basically an open chimney to the attic."

Rafael Vargas Santa Ana, CA · September 2025
★★★★★

"Straight answer to a straight question: yes it can be fixed, no you don't need a new one, here's what it costs. Took four minutes on the phone. The other place wanted to send someone out for a "consultation"."

Malik Prince Santa Ana Area · June 2026
★★★★★

"Attic was at maybe R-11 from the 1970s and blown in over the top would have just buried the problem. They removed the old material, air sealed the top plates and penetrations first, then blew in to R-49. The upstairs is a completely different house in August."

Steven Kim Santa Ana, CA · January 2025
★★★★★

"Handled the utility rebate paperwork, which knocked a real amount off the final cost."

Daniel Delaney Santa Ana, CA · March 2026
