Stair lifts

Stair Lift Cost Estimator

Rail type does more to your price than any other choice. Add the options a salesperson will offer and see the range.

Estimated installed cost

$2,800 – $5,200

This is the range we expect a written quote to fall within, including equipment and standard installation. If your quote is above the high end, ask what is different about your staircase.

An estimate is not a quote. Curved rails are custom fabricated, so a site measurement is the only way to get a firm number.

Most whole-home projects land in the lower half of this range because not every room needs the most expensive option.

Ranges are national installed estimates. Sequence work by risk: bathroom and entry first, stairs next, cosmetic changes last.
