Air Clearance Testing After Asbestos Abatement in Somerville
Post-Abatement Air Clearance and MassDEP Closeout Documentation
Air clearance testing is the final step in every asbestos abatement project. After containment is removed and the work area is cleaned, an independent air sample is collected and analyzed to confirm that airborne asbestos fiber concentrations are below the regulated threshold. This clearance test is required by MassDEP before the work area can be re-occupied and is the basis for project closeout documentation.
We provide air clearance testing as both a standalone service and as the final phase of our abatement projects. For property owners who hired a different abatement contractor and need independent clearance testing, we offer scheduling flexibility and fast turnaround on results so projects can close out on time.
What's Included in our Air Clearance Testing service?
Post-Abatement Air Sampling
We collect aggressive air samples from the work area after abatement and cleaning using PCM or TEM methodology as required by the project specification. Samples are submitted to an accredited laboratory and results are delivered with a written clearance report.
Phase Contrast & TEM Analysis
Air clearance sampling methodology is selected based on project type and regulatory requirement. Phase contrast microscopy is standard for most abatement clearances; transmission electron microscopy is used when more specific fiber identification is required.
MassDEP Closeout Documentation Package
Upon air clearance, we deliver a complete closeout documentation package including the clearance test report, laboratory analysis, and project summary — meeting MassDEP requirements and providing the property owner with a permanent record of the abatement project.

Frequently Asked Questions
Asbestos Removal can be complex, and we’re here to provide answers to common questions. Here are some frequently asked questions from our clients.
Frequently Asked Questions about Asbestos Removal Somerville MA
What types of asbestos-containing materials are common in Somerville homes?
Somerville's pre-1920 triple-deckers commonly contain asbestos in floor tiles, pipe insulation, plaster, roofing materials, and asbestos cement siding. Pre-1978 homes may also have it in joint compound and textured coatings. A professional inspection before any renovation is the safest approach.
What is the MassDEP 10-day notification requirement for asbestos abatement in Massachusetts?
Massachusetts requires contractors to submit a 10-day notification to MassDEP before most abatement projects begin. This applies to renovation projects that disturb asbestos-containing materials above threshold quantities. We handle this notification process on behalf of our clients as part of every qualifying project.
Is asbestos in my home dangerous if it hasn't been disturbed?
Asbestos-containing materials in good condition that are not being disturbed generally do not release fibers. The risk increases significantly when materials are cut, drilled, broken, or renovated. If you're planning any renovation in a Somerville home built before 1980, testing before demolition is strongly recommended.
How long does a residential asbestos abatement project take in Somerville?
Most residential abatement projects in Somerville take one to three days depending on scope. A single-room floor tile removal might be completed in a day. A larger project involving pipe insulation across a triple-decker may take two to three days plus time for post-abatement air clearance testing.
Do I need a licensed contractor to remove asbestos in Massachusetts?
Yes. Massachusetts law under 454 CMR 22.00 requires that asbestos abatement above certain thresholds be performed by a licensed contractor. All workers must hold a current DLS asbestos abatement license. Hiring an unlicensed contractor can result in regulatory violations and liability for the property owner.
What happens after asbestos is removed from a Somerville property?
After abatement is complete, an independent air clearance test confirms that fiber levels are below the safe threshold. We then deliver a full closeout documentation package including the disposal manifest and clearance report — required for MassDEP compliance and important for future property transactions.
Frequently Asked Questions about Air Clearance Testing
What is air clearance testing and why is it required after asbestos removal?
Air clearance testing measures airborne asbestos fiber concentrations in the work area after abatement and cleaning. Massachusetts regulations require the area to pass air clearance before re-occupancy. It is the final confirmation that abatement was successful and fibers are below safe thresholds.
How long after abatement can air clearance testing be performed?
Air clearance sampling is typically conducted after the work area has been cleaned and final visual inspection is complete. The aggressive sampling protocol agitates the air before samples are taken to represent worst-case conditions. Laboratory results typically return within one to three business days.
What happens if a Somerville property fails air clearance testing?
If air clearance sampling results exceed the regulated threshold, the work area must be recleaned and re-sampled before occupancy is permitted. We notify clients of any failing results immediately and coordinate next steps to get the project across the clearance threshold.
Can I use the same contractor for both abatement and air clearance testing?
In Massachusetts, air clearance testing can be conducted by the abatement contractor or by an independent industrial hygienist depending on project type. For projects where independent clearance is preferred, we provide clearance testing services separate from abatement work by other contractors.
