Cost to Remove Old Flooring — and When the Subfloor Is the Real Bill

Removal is the half of a flooring project nobody budgets for, and it is the half that decides whether your new floor lays dead flat or telegraphs every dip for the next fifteen years.

Removal cost by material

Existing floor	Per sq ft	Why
Carpet and pad	$0.50 – $1.25	Fast, but tack strip and every staple must come out
Laminate / floating	$0.75 – $1.50	Snaps apart quickly
Sheet vinyl, loose laid	$0.75 – $1.75	Easy unless it is glued at the perimeter
Glue-down vinyl / VCT	$1.50 – $3.00	Adhesive scraping is the slow part
Nailed hardwood	$1.75 – $3.50	Labor heavy, and often reveals subfloor damage
Ceramic tile and mortar	$2.50 – $5.00	The hardest tear-out in residential remodeling
Tile over backer board	$3.00 – $6.00	Backer is screwed every 8 inches
Multiple layers	Add 40 – 70%	Very common in older Twin Cities homes

Plus disposal: $300 to $900 per project for a dumpster, more for tile and mortar because it is heavy and priced by weight.

For a 500 square foot room, that means removal alone ranges from about $550 (carpet) to about $3,400 (tile with mortar and disposal).

Why tile removal costs what it does

Tile is not really the problem — the mortar bed is. Removing tile means jackhammering or chiseling the thinset off the subfloor, or cutting out the backer board and screws entirely. It generates enormous amounts of dust and it takes hours per hundred square feet.

Older homes sometimes have a mud-set tile floor — a two-inch reinforced mortar bed poured over the subfloor. That is demolition, not flooring removal, and it can double the number.

We use dust-shrouded equipment, plastic containment, and negative-air fans. That controls most of it. It does not control all of it, and anybody who promises dust-free tile removal has not done much of it.

The subfloor is where budgets actually break

You do not know what is under a floor until the floor is up. Common finds and what they cost:

Problem	Fix	Cost
Subfloor out of flat	Self-leveling underlayment	$2.00 – $5.00 / sq ft
Soft or rotted subfloor	Cut out and replace sections	$3.50 – $8.00 / sq ft
Squeaky subfloor	Screw down to joists	$1.00 – $2.50 / sq ft
Failed joist or water damage	Sister the joist	$300 – $1,200 each
Uneven layers / height mismatch	Add underlayment or plane	$1.50 – $4.00 / sq ft
Missing vapor barrier on slab	Install vapor retarder	$0.50 – $1.50 / sq ft

Where rot shows up most: around toilets, under dishwashers and refrigerators with ice makers, at exterior doors, and under any window that has leaked. If your house has had any of those, assume there is a chance.

Flatness matters more than people think. Most new flooring requires the subfloor to be flat within 3/16 inch over 10 feet. Luxury vinyl plank is especially unforgiving — over a dip, the planks flex, the locking joints work loose, and eventually they separate. That is almost always a subfloor problem being blamed on the flooring.

Asbestos — test before you disturb it

In homes built before roughly 1985, two materials are the classic suspects:

• 9-inch vinyl floor tile (and sometimes 12-inch)
• Black cutback adhesive under old sheet linoleum

Both can contain asbestos. Intact and undisturbed, they are not a hazard. Dry-scraping or sanding them is what creates one.

A lab test on a small sample costs $50 to $150 and takes a few days. If it comes back positive, abatement by a licensed contractor runs $8 to $18 per square foot — which is the kind of number that changes a project plan. Sometimes the right answer is to encapsulate: leave it in place and float the new floor over it.

Do not let anyone start ripping without knowing.

Can you leave the old floor in place?

Sometimes, and it saves real money:

Usually fine to cover:

• One layer of sound, well-adhered, flat sheet vinyl
• Sound ceramic tile, if the height increase works at doors and transitions
• A well-bonded slab

Never cover:

• Carpet
• Anything soft, hollow-sounding, or loose
• Anything with water damage or mold
• Multiple existing layers already stacked

The tradeoff is floor height. Every layer raises the finished floor, which means doors need trimming, appliances may not slide under counters, and transitions to adjacent rooms get awkward. Above about 3/8 inch of buildup, removal is usually the better answer.

How we quote it

We quote removal with an allowance for subfloor repair, and we do not spend the allowance without showing you what we found. Photos, the cost, and the options — before the work continues. Any contractor who gives you a firm all-in number on a tear-out sight unseen is either padding heavily or planning a change order.
