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.

Frequently Asked Questions

Often, yes especially for San Fernando Valley homes. Blown-in or high-density fiberglass batts deliver a strong balance of performance, cost, and installation speed. They reach the R-38 to R-49 levels typically recommended for our climate, are non-combustible, and are less prone to settling than cellulose when installed to manufacturer specs. Pair fiberglass with thorough air sealing and proper ventilation for the best results. That said, cellulose can be great for sound control, and spray foam excels at air sealing (at a higher price). Pure Eco Inc. will evaluate your attic’s access, wiring, ventilation, and moisture conditions to recommend the right fit—not just a one-size-fits-all material.
Review counts change over time, but Pure Eco Inc. is widely reviewed across Google, Yelp, Angi, and the BBB. The best way to build trust is to verify: check our live profiles, ask us for recent Chatsworth references, and request proof of licensing and insurance. We’re also happy to share before/after photos, scope details, and (when applicable) permit and testing documentation so you can validate quality not just read ratings.
Yes Chatsworth is in our core Los Angeles County service area. Our crews work the Valley daily, so assessments are often available within a few business days, with installations typically scheduled shortly thereafter. Timing depends on attic size and access, but travel and mobilization to Chatsworth are routine for Pure Eco Inc.
Use these checkpoints: 1) Target R-value: in our area, R-38 to R-49 is commonly recommended for attics. 2) Product: consider formaldehyde-free fiberglass with third-party certifications and a solid manufacturer warranty. 3) Scope: insist on air sealing, eave baffles, bath-fan ducting to exterior, damming around hatches, and depth markers for verification. 4) Contractor vetting: verify active license and insurance, ask for recent local references and job photos, and get a written scope with line-item pricing and a workmanship warranty. 5) Rebates: ask about available utility or state incentives and who handles the paperwork. Pure Eco Inc. provides a documented scope, photos, and warranty on every attic project.
