Before any tool touches 9×9 floor tile, the first move is to find out what it’s made of, not to start prying it up. Vinyl composition tile in the 9×9 size was manufactured widely from roughly 1940 through 1980, and a share of it — along with the black mastic often found underneath — contained asbestos. Testing, not guessing, is the step that comes first.
Why does the 9×9 size matter?
Tile size is one of the few visual clues that narrows down an installation date without lab work. Manufacturers moved toward the 12×12 format later in the 20th century, so a 9×9 tile is more likely to be an older product. Size alone does not confirm asbestos content — only testing does — but it is a reasonable reason to treat the floor with more caution than a tile you know was installed last decade.
Pennsylvania’s housing stock makes this more than a trivia point. The median home in the state was built in 1965, and a quarter of homes predate 1940, according to the U.S. Census Bureau’s American Community Survey. In cities like Scranton, Lancaster, and Reading, where more than half the housing stock predates 1940, a 9×9 tile floor in a kitchen or basement is a routine find, not a rare one. The by-city housing stock figures lay out how this varies block by block across the state.
How do you find out if it contains asbestos?
The only reliable way to know is a laboratory test on a sample of the tile and, separately, the adhesive underneath it. A homeowner can collect a small sample without extensive disturbance, but the testing itself belongs with an accredited lab, not a guess based on age or appearance. The EPA publishes general background on asbestos-containing materials in older homes, and that is the right starting point for understanding the process — not a flooring article.
What happens if you just cover it instead of removing it?
Covering an intact 9×9 tile floor, rather than removing it, is a common and often reasonable path once testing has clarified what’s there. Laminate, luxury vinyl plank, and some tile installations can go over a sound existing floor if the subfloor and height transitions allow it. The problem comes from the opposite instinct — sanding, scraping, or dry-sweeping old tile to “get it ready,” which is exactly the kind of disturbance that turns a dormant material into an airborne one. Removal or encapsulation decisions are the reader’s own next step, guided by the lab result and, where work is substantial, the reader’s municipality.
Does removing it require a permit?
That depends entirely on the municipality, not the state. Pennsylvania enforces building permits locally under the Uniform Construction Code, so whether a given floor project needs one is a question for the reader’s own borough or township office, not a statewide rule this article can state. If a contractor is involved in removal, the Pennsylvania Office of Attorney General maintains a public register of home improvement contractors, and checking it is a reasonable step before any agreement is signed.
What does replacement actually cost?
Once a floor is cleared — whether that means safe removal or an approved cover-over — the cost moves to ordinary flooring math. Removing the old floor runs $1-$4 per square foot on its own, and new tile installed typically runs $9-$14 per square foot. Those are planning ranges this site publishes to compare materials, not a quote for any specific room; subfloor condition, tile size, and layout complexity all move the final number. The flooring cost estimator walks through those variables for a specific project, and the cost hub breaks ranges down by material and by city.
What’s underneath matters too
In houses old enough to carry 9×9 tile, what’s beneath it is rarely a simple plywood subfloor. Diagonal 1×6 plank subfloors are common in this era and change what can go on top of them, and joists built to older deflection standards can crack a rigid tile reinstalled a few winters later. Both are covered in detail in the diagonal plank subfloor guide and in why old floor joists crack tile two winters later. The old-house flooring hub and the old Pennsylvania houses archive cover the rest of what a pre-1960 floor tends to hide — including whether there’s hardwood sitting under it that’s worth more than the tile ever was. For a wider comparison of what belongs where, the flooring materials hub lays out what each option is actually good at.
PA Floors is an independent Pennsylvania flooring resource. We do not sell or install flooring, we do not quote jobs, and nobody from this site will call you. Cost figures here are published planning ranges for Pennsylvania, not quotes — what you actually pay depends on your rooms, your subfloor and the material you choose, and the final price depends on your project. Photography is licensed stock used to illustrate materials and rooms; it is not work by anyone connected to this site. Building code and permit requirements are enforced locally in Pennsylvania, so confirm anything regulatory with your own municipality before you rely on it.
