Disposing of Asbestos Tiles: A Homeowner’s Guide

We may earn commission from links on this page. Lead-form submissions are forwarded to local inspector partners. How we research and review.

Old 9×9 and 12×12 floor tiles are among the most common asbestos-containing materials in American homes, and they tend to surface at inconvenient times: a basement finish, a kitchen remodel, a water leak that lifts a few squares. Once tiles are suspected or confirmed to contain asbestos, the question shifts from “what is this?” to “how does it leave the house without creating a hazard or breaking a rule?” Disposing of asbestos tiles is not like hauling remodeling debris to the curb. Breaking, sanding or dry-scraping tiles can release fibers, and asbestos waste generally has to be wetted, sealed, labeled and taken to a landfill that accepts it. This guide covers testing first, the options for dealing with tile (leave it, cover it or remove it), how removed tile is usually packaged, where it can go, what to do about the black mastic underneath, how federal and Colorado rules come into play and what affects cost. It is general information for Colorado Front Range homeowners, not legal advice; confirm current state and local requirements before starting any work.

Start With Testing, Not a Scraper

You cannot tell whether a tile contains asbestos by looking at it. The EPA’s Protect Your Family page says that, generally, you cannot tell whether a material contains asbestos simply by looking at it unless it is labeled, and that if in doubt you should treat the material as if it contains asbestos and leave it alone. The same page recommends that samples be taken by a trained and accredited asbestos professional, noting that sampling done incorrectly can be more hazardous than leaving the material alone.

Age and appearance offer clues. Tile from roughly the 1950s through the early 1980s, especially 9×9 squares and some 12×12 styles, deserves suspicion, and so does the black adhesive often found under it. The guide on how to tell if floor tiles contain asbestos lays out the visual and historical clues, and the guide to asbestos tile testing explains sampling and lab options.

Test the tile and the mastic separately when possible. They are different materials and can produce different results. A negative tile over a positive mastic changes the removal plan, and so does the reverse. If the tile tests negative and the mastic tests negative, ordinary demolition and disposal rules usually apply.

What OSHA assumes about old flooring

OSHA’s construction asbestos standard, 29 CFR 1926.1101, says asphalt and vinyl flooring material installed no later than 1980 must be considered asbestos-containing unless the employer or building owner determines that it is not, and that resilient flooring including associated mastic and backing is to be assumed asbestos-containing unless an industrial hygienist determines it is asbestos-free using recognized analytical techniques. That rule governs employers and workers, not homeowners doing their own projects, but it is a strong signal that older flooring should be treated with caution until tested.

Your Options: Leave It, Cover It or Remove It

Disposal is only necessary if tiles are actually coming out. In many homes, they do not have to.

Leave intact tile in place

EPA’s homeowner guidance says that, usually, the best thing is to leave asbestos-containing material alone if it is in good condition, and that material in good condition that will not be disturbed will not release asbestos fibers. Intact tile that is not cracked, crumbling or lifting can often stay where it is.

Cover it with new flooring

EPA’s do’s and don’ts list says that when asbestos flooring needs replacing, install new floor covering over it if possible. Floating floors, underlayment with new vinyl plank, or carpet over intact tile avoid disturbing it entirely. This is often the cheapest and lowest-risk option, though it adds floor height and the tile remains in the house for future owners to manage and, in many cases, to disclose at sale.

Professional removal

Professional abatement is the usual path when tiles are damaged, when they are in the way of a remodel that requires a bare subfloor, or when the area is large. A licensed or certified contractor handles containment, wet removal, packaging, transport and disposal. EPA advises that removal and major repair be done by people trained and qualified in handling asbestos. The guide on asbestos floor tile removal describes what that process looks like.

Homeowner removal where locally allowed

Some jurisdictions allow homeowners to remove limited amounts of asbestos flooring from their own single-family residence, subject to conditions. In Colorado, asbestos in renovations and demolitions is regulated by the state under Air Quality Control Commission Regulation No. 8, and rules can include inspection, certification, notification and disposal requirements that depend on the amount of material and the type of building. Local landfills also set their own acceptance rules. Do not assume homeowner removal is allowed; confirm current requirements with the state asbestos program and your intended landfill before touching a tile. Even where it is allowed, it may not be wise for large areas, damaged tile or households with children or people with lung conditions.

How Federal Rules Apply to a House

The EPA asbestos laws and regulations page describes the asbestos National Emission Standards for Hazardous Air Pollutants (NESHAP). According to that page, the NESHAP specifies work practices for asbestos during demolitions and renovations of all structures, installations and buildings, excluding residential buildings that have four or fewer dwelling units. It also requires the owner or operator to notify the appropriate state agency before any demolition, or before renovations of buildings that could contain a certain threshold amount of asbestos-containing material.

So, in plain terms, the federal NESHAP work-practice rules generally do not cover a typical single-family home or small multiplex as described on that page. That is not the same as “no rules apply.” State rules can be broader than the federal ones, OSHA’s standard applies whenever an employer’s workers do the job, and landfills have their own requirements. Treat the federal residential exclusion as one piece of the picture, not permission to skip precautions.

OSHA Class 2 work practices for flooring

OSHA’s standard defines Class 2 asbestos work as removal of asbestos-containing material that is not thermal system insulation or surfacing material, specifically including floor tile and sheeting, roofing and siding shingles, and construction mastics. For vinyl and asphalt flooring, the standard’s work practices include the following:

• Flooring or its backing shall not be sanded.
• Floors are cleaned with vacuums equipped with HEPA filters, disposable dust bags and a metal floor tool with no brush.
• Scraping of residual adhesive or backing is performed using wet methods.
• Dry sweeping is prohibited.
• Mechanical chipping is prohibited unless done inside a negative-pressure enclosure.
• Tiles are removed intact unless the employer shows that intact removal is not possible; when tiles are heated and can be removed intact, wetting may be omitted.

These rules bind employers, but they are a sensible model for anyone near the work. The guide explaining how asbestos floor tile behaves when disturbed adds context on why intact removal matters.

Step-by-Step: Removal, Packaging and Disposal

The table below summarizes the typical sequence used for asbestos tile removal and disposal. Professional crews follow their own procedures and state requirements, which may be stricter. It is shown so homeowners know what to expect and what to ask about, not as a substitute for training.

Packaging details

Keep tiles wet until sealed. Avoid overfilling bags; heavy, sharp-edged tiles can tear plastic, which is one reason double-bagging is standard. Some landfills or rules call for a specific bag thickness, a warning label or wrapping larger pieces in sheeting rather than bagging them. Disposable coveralls, plastic sheeting from containment and used respirator cartridges usually go into the waste bags too.

Respiratory protection

A paper dust mask is not adequate for asbestos. The guide to masks for asbestos removal explains respirator types, filter ratings and fit. A respirator only works if it fits and is used correctly, and it does not make a poor removal method safe.

Where Asbestos Tiles Can Go

Asbestos tile cannot go in household trash, a curbside bin or a general construction dumpster. It belongs at a landfill or facility approved to accept asbestos waste. Practical points:

• Call ahead. Ask whether the facility accepts non-friable asbestos flooring from homeowners, what packaging and labeling it requires, whether an appointment is needed and what it charges.
• Ask about paperwork. Some facilities ask for a waste manifest, test results or contact details. Professional contractors usually handle this as part of the job.
• Transport carefully. Keep sealed bags in a truck bed or trailer rather than the passenger area, and secure them so they do not tear.
• Keep records. Save receipts and any disposal documents with your house records.

The general guide on asbestos disposal covers other materials such as pipe wrap and siding.

Friable versus non-friable

Intact vinyl-asbestos tile is generally treated as non-friable, meaning the asbestos is bound in the material and does not crumble under hand pressure. Tile that has been broken up, burned or ground can become friable and is often subject to stricter handling. That is another reason to remove tile whole. The guide to vinyl asbestos tile covers the material in more depth.

The Mastic Question

Black cutback adhesive under old tile is a frequent complication. It may contain asbestos even when the tile does not, or the other way around. Mastic is also hard to remove cleanly. Scraping it dry, grinding it or using a sander can release fibers, and OSHA’s flooring practices call for wet methods for any scraping of residual adhesive. EPA’s homeowner list adds that you should not sand or try to level asbestos flooring or its backing.

Options include leaving the mastic in place under new flooring, covering it with a compatible leveling compound or underlayment, or professional removal with chemical or wet methods. Some solvents used on mastic carry their own fire and fume hazards, so professional handling is often worth it. The asbestos mastic guide covers testing and removal choices.

What Removal and Disposal Cost

Costs vary widely with area, condition, mastic, access, state requirements and local disposal fees. Professional abatement for a small room can carry a minimum charge that makes per-square-foot comparisons misleading, while large open areas may price more efficiently. Disposal itself is usually a smaller part of the total than labor, containment and mastic removal, but landfill fees and hauling still add up.

Main cost drivers include:

• Square footage and the number of rooms involved.
• Whether the mastic contains asbestos and must also be removed.
• Tile condition: intact tiles come up faster than broken or brittle ones.
• Containment needs, including HVAC isolation and negative air.
• Testing and any clearance or air sampling.
• Disposal fees, distance to an approved landfill and minimum job charges.

For ranges and examples, see the guides on asbestos tile removal cost and the broader asbestos removal price guide. When comparing professional quotes, check that each one includes disposal, mastic handling, containment and cleanup, so you are not comparing a full job with a partial one.

Hiring an Abatement Contractor

For most homeowners, especially with larger areas, damaged tile or asbestos mastic, hiring a professional is the simplest way to get the tile out and properly disposed of. EPA’s Protect Your Family page describes asbestos professionals as trained and accredited, and it suggests that homeowners check credentials and avoid conflicts of interest, such as hiring the same firm to both assess and remove material without an independent check. A few questions help separate careful contractors from casual ones:

• Are you certified or licensed for asbestos work under Colorado’s program, and can you show current credentials?
• Will you file any notification the state requires for this job?
• How will you contain the work area and protect the HVAC system?
• Will tiles be removed intact and wet, and how will mastic be handled?
• Where will the waste go, and will you provide disposal documentation?
• Is air monitoring or a clearance check included, and who performs it?

EPA’s page also points out that federal law does not require people who inspect, repair or remove asbestos-containing materials in detached single-family homes to be trained and accredited, but that some states and localities do, and it advises homeowners to make sure the workers they hire are trained and accredited anyway. It recommends using two different firms for assessment and removal to avoid a conflict of interest, and checking a firm’s past performance and any safety violations with local agencies. State agencies keep the most current lists of accredited professionals.

Ask for the answers in writing, and compare at least two bids. A noticeably low quote sometimes leaves out mastic removal, disposal fees or cleanup, which tend to reappear later as change orders.

Colorado Considerations

Colorado manages asbestos in buildings through its state program under Air Quality Control Commission Regulation No. 8. Depending on the amount of material, the building type and who is doing the work, the rules can involve inspection by a certified inspector before renovation or demolition, the use of certified abatement contractors, state notification, permits and specific disposal practices. Some provisions for single-family homes differ from those for commercial and multifamily buildings, and thresholds and procedures change over time, so read the current rules or contact the state program instead of relying on a summary or an older forum post.

Local factors matter too. Front Range landfills differ on whether they accept asbestos from homeowners at all, what packaging and paperwork they require and what they charge. Some cities and counties also have their own building-permit requirements for remodels that involve asbestos. A few phone calls before starting can save a wasted trip with a truck full of sealed bags.

Mistakes to Avoid

• Breaking tiles to get them up faster. Broken tile releases more fibers and can make waste friable.
• Using a floor sander, grinder or power stripper. EPA warns never to use a power stripper on flooring that may contain asbestos.
• Dry sweeping or household vacuuming. Both put fine dust back into the air.
• Mixing asbestos tile into regular demolition debris. It can contaminate the dumpster load and may violate disposal rules.
• Skipping the call to the landfill. Showing up unannounced with asbestos bags can mean being turned away.
• Tracking debris through the house. EPA advises against tracking possible asbestos material through the home; wet-mop any unavoidable pathways.
• Forgetting the mastic. A clean tile result does not clear the adhesive.

Living With Tile You Decide to Keep

If testing confirms asbestos but the tile is intact and staying, a few habits keep it that way. Avoid dragging heavy furniture or appliances across it, keep it dry, and do not wax-strip it with abrasive pads. Note the location and test results in your house records so future contractors know before they cut or drill. When selling, check what disclosure your contract and state forms require. If tiles start to crack or lift, revisit the cover-or-remove decision rather than letting damage spread.
