Is There Asbestos in Your Brentwood Home?

Homes and buildings built before 1980 are most at risk. Approximately 45% of Brentwood's housing stock predates 1980. Common locations include:

Popcorn/textured ceilings (common in homes built 1960–1978)
Floor tiles and tile adhesive (9" vinyl floor tiles are a major red flag)
Pipe insulation and duct wrap in older HVAC systems
Attic insulation, particularly vermiculite (gray, pebble-like material from Libby, MT)
Roof shingles and siding on pre-1980 construction
Drywall joint compound and textured paint used before 1980
Brentwood (East Contra Costa County) experienced rapid growth in the 1990s–2000s, but older structures along downtown and older neighborhoods contain pre-1980 asbestos materials including floor tile adhesive and textured drywall.
Bay Area AQMD Regulation 11, Rule 2 requires 10-day advance notification for qualifying renovation and demolition projects in Contra Costa County.
State-specific licensing requirements apply under Cal/OSHA 8 CCR 1529.

Questions to Ask Before Hiring in Brentwood

A legitimate contractor will answer all of these without hesitation.

Are you licensed and accredited in California?

Ask for their California Department of Industrial Relations, Division of Occupational Safety and Health (Cal/OSHA); contractors registered via ACRU; CSLB C-22 classification license number and verify it on the state licensing database. Federal AHERA accreditation is also required for supervisors and workers.

Will you file the required notification with Local Air Quality Management District — Bay Area AQMD (Regulation 11, Rule 2) for Contra Costa County (Brentwood); Sacramento Metro Air Quality Management District for Woodland; South Coast AQMD Rule 1403 for Arcadia/San Gabriel Valley; San Diego County APCD Rule 36 for Santee; Alameda County / BAAQMD for Dublin?

Yes — they must file at least 10 working days before work begins. Ask to see the filed notification or confirmation number.

How will the asbestos waste be disposed of?

Ask for the name and location of the licensed TSCA-permitted disposal facility they use, and request a copy of the waste manifest. Do not accept vague answers.

What containment methods do you use?

Proper abatement requires critical barriers, negative air pressure machines with HEPA filtration, and full-body PPE. Ask for their written work plan before signing any contract.

Do you carry liability insurance and workers' compensation?

Ask for a certificate of insurance naming you as an additional insured. Minimum $1 million general liability for residential projects; higher for commercial.

Will you provide a written clearance air sample report after abatement?

Post-abatement air clearance testing by a separate third-party industrial hygienist is best practice and often required for commercial projects in California.

Can you provide references from recent Brentwood-area projects?

Ask for three references from projects completed in the past 12 months. A reputable contractor will have them readily available.

What does your written contract include?

The contract should include: scope of work, start and end dates, containment plan, disposal facility name, payment schedule, and a clause requiring regulatory compliance. Never pay more than 30% upfront.
