Excellent service by Beni, Henry and others at Pure Eco. They completed the job really quickly, cleaned, rodent proofed and reinstalled insulation in our attic. They made sure to section off the work area so that the rest of the house clean. I would definitely recommend them.

Pulling my former 5 star review because PureEco was great until I asked them to pull a permit in order for me to get the DWP rebate. (Mind you, all attic insulation in Los Angeles requires a permit.) I faced a steady barrage of phone calls from upper management, arguing with me why they couldn’t do it, even had the project manager tell me it wouldn’t pass (it did.) Another major issue with them to be very aware of is Warren the VP and Beni the project manager stated they have a “minimum charge” which appears to be about $3300K — so it didn’t matter that my 1180 square foot project should have pencilled out to $1770, with their ads stating attic cleaning included which was verified by two other staff members. So ignore the $1.89 a square foot (they did lower mine to $1.50 because I supplied the insulation) because they’re going to charge you what they’re going to charge you regardless. False advertising! They also claimed there’s a disclaimer, but I could find zero disclaimers in their ads and in their contract. Henry led a great and probably underpaid work crew, no issues with them, but management leaves much to be desired. Pay attention; get everything in writing; and ask if cleaning is included in the price as the ads and their website states. I withheld $500 for my time dealing with them which I thought was fair given that I was overcharged and that work stated as included in their ad was not performed or I was charged for it (attic cleaning and vent sealing), only to have VP Warren threaten me with collections and a mechanics lien. So I paid it and wrote this review so others may be aware of their tactics.

FAQ: Attic Insulation in Chatsworth

Short answer: the one that stops your attic from auditioning as a pizza oven. Practical answer: start with air sealing, then add blown-in cellulose or fiberglass to at least R-38 to R-49 (go R-60 if you want your AC to whisper thank you). Spray foam is the premium pick for unvented or complex roofs, and a radiant barrier can help with Valley heat. Pure Eco Inc. will inspect, seal, add baffles, and recommend the combo that fits your roof, budget, and sweat tolerance.
Review counts change faster than LA gas prices, so check Google, Yelp, and the BBB for the live number. Trust the patterns: lots of recent reviews, detailed write-ups, job photos, and professional responses to the occasional hiccup. Then verify the CSLB license and insurance, and ask for a couple of local references. If Pure Eco Inc. checks those boxes, you can trust them without crossing your fingers.
Yes. Pure Eco Inc. regularly serves Chatsworth and the greater San Fernando Valley, plus much of Los Angeles County. If your home is within normal LA driving reality, you are probably covered; call with your ZIP and a time that avoids the 101's mood swings.
Use this cheat sheet: insist on an in-attic inspection; get an itemized scope that includes air sealing, baffles, damming, and proper R-value (aim R-38 to R-49+); confirm CSLB license, workers' comp, and liability; ask about rodent remediation, bath-fan venting, and meticulous cleanup; request before-after photos and depth markers; check local rebates from LADWP or SoCalGas. Pure Eco Inc. can walk you through every step so your attic goes from haunted to insulated.
