About IDI

Trusted by public agencies. Ready for your project.

Interior Demolition, Inc. has worked across Southern California since 1983, growing from a specialized interior demolition contractor into an integrated demolition, abatement, earthwork, crushing, and disaster debris cleanup company.

Our public-sector experience is documented by public record, including a 2024 Los Angeles County on-call cleanup and demolition award and prior City of Los Angeles Bureau of Engineering on-call demolition contracts. For general contractors and agencies, that means IDI is not just claiming capability — the company has been selected for accountable, on-call work.

How We Work

A predictable process.

No surprises mid-job. Same workflow whether you're a GC running a $40k strip-out or a public agency awarding a multi-phase debris recovery.

Walkthrough & Survey

On-site walk to scope structure, utilities, hazards, and access. Suspect ACM and lead are flagged for licensed sampling.

Quote & Schedule

Line-item proposal with timing, equipment, crew size, abatement, hauling, and recycling assumptions clearly stated.

Execute Safely

Cal/OSHA-compliant work plan. Negative-pressure containment for abatement. Owned equipment, in-house crews, daily reporting.

Document & Close

Waste manifests, recycling tickets, air-clearance reports, and a broom-clean site ready for the next trade.

Sustainability isn't a tagline — it's 65–100% of every load. LEED-Compliant Practices · Waste Management Recycling Program · On-Site Crushing
