Flooring Installation Over Existing Floors
Installing over an existing floor saves removal costs of $1.50–$3.50 per square foot (tile $2–$7). It works in many cases, but only when the old floor is flat, solid and suited to the new material.
What can usually go over what
| Existing floor | New floating LVP or laminate | New tile | New glue-down vinyl |
|---|---|---|---|
| Sheet vinyl or vinyl tile (one layer, well bonded) | Often yes | Sometimes, with prep | Often yes, with prep |
| Ceramic tile (flat, solid) | Often yes | Sometimes, with a bonding primer | Usually needs leveling compound |
| Hardwood (solid, flat) | Often yes | Not usually | Not usually |
| Carpet | No; remove it | No | No |
General guidance only. The new product's installation instructions decide; following them keeps the warranty valid.
Check before you decide
- Flatness: many floating floors allow only a small variation, often around 3/16 inch over 10 feet. Check your product's instructions.
- Movement: squeaks, soft spots or loose tiles must be fixed first (subfloor repair).
- Moisture: concrete slabs and basements should be moisture-tested.
- Layers: most manufacturers limit how many old layers can stay.
Older vinyl tiles and sheet flooring (and the adhesive under them) can contain asbestos. Do not sand, scrape or break them up. Covering them in place is often the safer choice; have them tested if they need to come up.
Plan for height changes
- Doors may need to be trimmed to clear the new floor.
- Transitions to other rooms can become trip hazards; plan transition strips.
- Dishwashers and refrigerators may not fit back under counters.
- Stair nosings and the height of the first and last steps must stay consistent for safety.
- Baseboards may need to come off and go back on, or you may need quarter round.
