Often found in attics, this insulation looks like loose, pebble-like, grey-brown, or silver-gold gravel and sparkles slightly under light. It was typically poured between attic floor joists rather than installed in rolls. The vast majority of vermiculite sold in the U.S. until the 1990s came from a mine contaminated with asbestos and must be treated as hazardous material.
Common in basements, around boilers, and in utility spaces, this insulation looks like white plaster or corrugated cardboard wrapped around hot water pipes, furnaces, and heating ducts. As it ages, it becomes extremely brittle and can release fibers with the slightest vibration or contact.
If your attic has Zonolite vermiculite insulation, you may be eligible for a significant rebate on your project cost.
Our Role As Your Expert Guide:
At Alberca Construction, we don't just safely remove the material; we also provide all the detailed documentation and guidance necessary to file your claim with the ZAI Trust. Our goal is to make your home safe while helping you maximize your rebate.
The removal of friable insulation requires the highest level of care and specialized equipment.
We create a full airtight containment and use powerful negative air pressure systems to ensure air flows into the work zone, not out.
For loose vermiculite, we use specialized HEPA-filtered vacuums that capture material directly into sealed waste bags. For pipe wrapping, we wet it and remove it in sections, immediately wrapping it to prevent fiber release.
Once the main material is removed, all surfaces within the containment are meticulously cleaned with HEPA vacuums and wet cleaning methods
We coordinate third-party air quality testing to certify that the area is completely clean, safe, and ready for new insulation installation.
Asbestos is a naturally occurring mineral composed of microscopic fibers. Due to its heat resistance and durability, it was heavily used in building materials until the 1980s. It is dangerous because, if disturbed, it releases these fibers into the air. When inhaled, they can become lodged in the lungs and, over time, cause serious illnesses like asbestosis and cancer.
It's impossible to know just by looking. Generally, if your home was built before 1985, there is a chance it contains asbestos in materials like attic insulation (vermiculite), floor tiles, popcorn ceilings, exterior siding, or pipe wrap. The only way to be 100% certain is through laboratory testing.
No, never. Taking a sample yourself without the proper equipment and protocols can be very dangerous, as it can release a high concentration of fibers in a small area. You should always contact a certified professional for inspection and sampling. We coordinate this service with independent firms to ensure your safety. (You can read more on our [Asbestos Inspection & Testing] page).
It depends on the scope and location of the project. For small, well-contained jobs, it may be possible to remain in the house. For larger projects, especially those in high-traffic areas or involving the HVAC system, we recommend arranging to be off the property. Your family's safety is our #1 priority, and we will always give you a clear and honest recommendation for your specific situation.
The duration varies depending on the size and complexity of the job. A small project in a basement might take 1-2 days. A full attic abatement could take 3-5 days or more. Your detailed estimate will include a projected timeline.
Asbestos is a regulated hazardous waste. All material is placed in sealed and labeled bags or containers according to EPA and CT DEEP regulations. It is then transported by licensed haulers to a specific landfill that is licensed to receive asbestos waste. We provide you with all disposal documentation for your records.
The cost varies and depends on several factors: the amount of material to be removed, its location and accessibility, and the type of material (loose vermiculite is different from floor tiles). This is why we cannot give a price without seeing the site. What we do guarantee is a detailed, transparent estimate with no hidden costs.
Yes, absolutely. Our initial site visit to assess the project and provide you with a detailed estimate is completely free and without obligation.
Yes! The most notable case is the ZAI Trust, which can reimburse homeowners for a significant portion of the cost of vermiculite insulation removal. We are very familiar with this process and can guide you through it. (You can read more on our Rebates & Cost-Saving Programs page).
Yes. Alberca Construction Company LLC holds all required licenses from the state of Connecticut for asbestos and hazardous material abatement. We also carry full general liability insurance and a specific pollution liability insurance policy for your complete protection and peace of mind. (You can see more on our Certifications page).
We serve the entire state of Connecticut from our base in Hartford.
We try to be as flexible as possible. Generally, once an estimate is approved, we can schedule work to begin within 1-2 weeks, depending on our current workload. For emergency situations, we will do everything we can to assist you sooner.
