TL;DR
Add the stairs. Stairs carry the highest soil concentration in the house and typically cost $2 to $5 per step, so a standard flight adds roughly $30 to $75 to a job. Skipping them leaves the dirtiest surface in the home untouched, and it is immediately visible next to freshly cleaned floors on both levels.
Why Are Stairs Priced Separately?
Because they take longer per square foot than any other surface. A technician on open floor moves a wand in long passes and covers area quickly. On stairs, the work is done with a small hand tool, on the riser and the tread and the nosing separately, kneeling and repositioning every step.
There is also the hose management problem. Running a solution line and a vacuum line up a staircase without dragging them across freshly cleaned carpet is genuinely awkward, and it slows the job further.
Add the soil load. Stairs concentrate all the foot traffic in the house into a narrow strip. Every person going up or down uses roughly the same twelve inches of each tread. Our piece on why stairs cost extra covers the full breakdown.
What Do Stairs Cost to Clean?
Industry Baseline Range
| Item | Typical published industry range |
|---|---|
| Per step | $2 to $5 |
| Standard flight, 13 to 16 steps | $30 to $75 |
| Two flights | $60 to $150 |
| Landing, when charged as a step | $2 to $5 |
| Landing, when charged as a small room | $10 to $30 |
| Pet urine treatment on stairs | $40 to $150+ |
These figures reflect published industry averages. Current market pricing varies significantly and actual quotes may fall well outside these ranges based on site-specific conditions, material costs, and project complexity.
Current Market Reality
Per-step rates have moved up alongside labor costs, since stair cleaning is almost pure technician time with very little equipment leverage. That also means stair pricing is one of the least negotiable line items in a quote. A company discounting stairs steeply is usually planning to work them fast, which on stairs means a single quick pass rather than the multiple passes the surface actually needs. Our comparison of flat rate or per square foot pricing covers how stairs sit outside both models.
Why Skipping Stairs Looks Worse Than Skipping a Room
A skipped bedroom is behind a door. A skipped staircase sits between two freshly cleaned levels, in the most visible circulation space in the house, in direct comparison with the carpet at the top and bottom.
The contrast effect is severe because the stairs were already the dirtiest surface. Cleaning the hallway above and the entry below and leaving the connector between them produces the most noticeable possible result: a dark ribbon running through a clean house.
If budget is the constraint, it is almost always better to skip a low-traffic bedroom and keep the stairs than the reverse.
Where the Soil Actually Sits on a Staircase
Knowing this helps you judge the work.
The tread nose, the front edge of each step, takes the most abrasion and the most soil. It is also the hardest part to clean because the tool has to wrap the curve.
The center of each tread, in the walking path, holds the general soil load.
The riser, the vertical face, collects scuffs, pet hair, and splash from shoes. Many fast operators skip risers entirely, which is a good thing to ask about.
The perimeter and the corner where tread meets riser accumulates the fine soil that vacuums miss. On stairs with a runner over hard flooring, the edges are where it collects.
Ask specifically whether risers are included. It is one of the most common silent exclusions in stair pricing.
Can Stairs Be Cleaned Safely?
Yes, with two cautions worth knowing.
Wet stairs are a slip hazard, and they stay damp longer than open floor because airflow across a staircase is poor. A well-run job leaves stairs damp rather than wet, and a fan positioned at the top or bottom helps considerably. Plan on not using the stairs in socks for several hours.
Over-wetting a staircase is worse than over-wetting a floor, because water runs downhill. Excess moisture migrates to the bottom step and the landing, where it can sit in the pad. That is why stair cleaning uses less liquid and more dry passes. Our guide on can you steam clean carpeted stairs covers the method question.
When Skipping Stairs Is Reasonable
There are a few honest cases.
The stairs are not carpeted. Obvious, but worth confirming in the quote, since some companies quote a house template that assumes they are.
The stairs are hardwood with a removable runner, which may be better cleaned as a rug.
The stairs are scheduled for replacement in the next few months.
The staircase is genuinely unused, such as a back stair in a large house that nobody takes.
Beyond those, skipping is usually a false economy. You save $30 to $75 on the surface that most visibly represents whether the house was cleaned.
Can You Do the Stairs Yourself?
You can, and it is one of the more practical DIY carpet jobs because the area is small and a portable spot machine handles it reasonably well. The technique matters more than the equipment: vacuum thoroughly first including the corners with a crevice tool, work top to bottom, use minimal solution, and make several dry passes on each step.
The two mistakes to avoid are over-wetting, which sends water to the bottom of the flight, and scrubbing the nose of the tread, which untwists the yarn on the part of the step that is already the most worn. Our guide on how to clean carpeted stairs walks through the sequence.
If there is pet urine on the stairs, the situation is different, because urine runs down and collects at the back of the tread and inside the riser joint. That is covered in pet urine on carpeted stairs.
The Decision Rule
Add the stairs to any job that includes carpet on both levels. Add them to any job before a listing, a showing, or a move-out inspection. Add them if there are pets, because stairs collect hair and dander at a rate no other surface matches.
Skip them only if they are uncarpeted, unused, or being replaced. And if the budget is tight, drop a bedroom instead. Nobody notices an unclean guest room. Everybody walks the stairs.
FAQ
How much does it cost to clean carpeted stairs?
Typically $2 to $5 per step, which puts a standard 13 to 16 step flight at roughly $30 to $75. Pricing is per step because stairs are hand-worked rather than cleaned with a wand, and they take substantially longer per square foot than open floor.
Are stairs included in carpet cleaning?
Almost never in a base price or an advertised room package. Stairs are a separate line item in nearly every pricing model, and landings are handled inconsistently. Confirm the step count, the rate, and whether risers are included before booking.
Are carpeted stairs dirtier than the rest of the house?
Generally yes. Every trip between floors passes through the same narrow strip of each tread, which concentrates soil and abrasion far more than an open room. Stairs are also harder to vacuum thoroughly, so dry soil accumulates in the corners.
How long do carpeted stairs take to dry?
Usually longer than open floor, because airflow across a staircase is poor. Expect several hours before walking on them in socks, and position a fan at the top or bottom to help. A properly cleaned staircase should be left damp, not wet.
Should risers be cleaned too?
Yes, and they are one of the most commonly skipped surfaces. Risers collect scuffs, splash from shoes, and pet hair, and a staircase with clean treads and dirty risers looks obviously half done. Ask whether risers are included in the per-step price.
Can I clean stairs with a rental machine?
You can, and stairs are one of the better DIY carpet jobs because the area is small. Use the upholstery or hand tool rather than the floor head, use minimal solution, and make extra dry passes so water does not run down and collect at the bottom of the flight.
