Wet Lobby Floor Cleaning Portland: October to May

RKA Cleaning keeps lobby floors clean, dry and safe in Portland office and apartment buildings from October through May. This page is the wet lobby floor cleaning Portland plan our crew runs in the rainy season. It is for the property manager with 1 or more buildings in the city. Portland gets about 36 inches of rain a year, and most of it falls across the 8 months from October through May. The page gives you 1 schedule table, the order of a visit, how we set the price, and what you get after each visit.

Why Portland lobby floors fail between October and May

Water and grit come in on every shoe. The entry zone takes most of it. Our janitorial service in Portland page says it plainly: entry mats hold water by 9:30 AM, and hard floors become slip risks before lunch. Downtown buildings near MAX stops get thousands of wet feet. See our commercial cleaning in Portland page for the routes we run.

Wet grit does the damage. Our commercial cleaning page puts it this way: Portland rain means constant moisture abuse from October through May. A daily mop does not remove embedded dirt or restore a worn finish.

The season also closes the repair window. Portland’s humidity slows wax cure. A recoat in November does not cure the way a recoat in September does. Our hard floor care page lists what a lost finish costs: VCT runs $2 to 5 per square foot installed to replace. Commercial floor cleaning Portland managers buy for the wet months must keep water and grit off the finish.

What the crew does on a rainy-season lobby visit

This is the order of work on 1 visit. The periodic floor work, such as a buff or a recoat, is a separate job. The schedule section covers it.

1. The crew checks in on the digital log.
2. The crew lifts each entry mat and vacuums the grit under it with a ProTeam HEPA vacuum. Then it vacuums the mat face.
3. The crew rotates the entry mats.
4. The crew dust-mops the hard floor from the door inward. This lifts dry grit before any water touches the floor.
5. The crew sets wet-floor signs before the mop touches the floor.
6. The crew wipes the door glass, the push bars and the mat edges with color-coded microfiber cloths. Glass and hardware come before the floor so nothing drips onto a pass the crew already finished.
7. The crew damp-mops the finished floor with a neutral cleaner, 2-bucket or a flat mop with a fresh pad per zone. In winter it uses salt-residue chemistry on the entry zone.
8. The crew checks the transition strip from tile to carpet. Entry carpet extraction is a separate job on a quarterly rotation, the interval the Carpet and Rug Institute sets for heavy-traffic areas.
9. The crew logs a loose mat edge, a cracked tile or standing water as a maintenance issue for the property manager.
10. The crew photographs the entry, the lobby floor and the mat station. It removes the wet-floor signs when the floor is dry, then checks out.

The crew uses EPA Safer Choice certified cleaners where one exists for the job. Safer Choice does not cover disinfectants; EPA certifies those under its Design for the Environment logo. See what a cleaning scope includes for how mat rotation and a higher mop frequency fit into a wet-month scope.

The rainy-season lobby floor schedule

Copy this table into your scope. Use the Copy table button to paste it into Excel or Google Sheets, or click Download CSV. The rows are the floor maintenance program RKA runs on a Portland lobby from October through May.

Office lobbies and apartment lobbies do not carry the same load. An apartment lobby gets foot traffic 7 days a week, so it gets the monthly high-touch pass on top of daily cleaning. Our janitorial Portland page puts it this way. High-traffic apartment buildings need monthly high-touch passes, especially in the rainy October-to-May window when entry mats stay saturated. An office lobby gets most of its traffic Monday to Friday. That leaves the weekend open for the periodic work, such as the strip and wax or a buff.

Entry mats stop the water at the door

A mat that is wet by 9:30 AM protects nothing after 9:30 AM. That is why RKA rotates mats each visit, not each week. Our Portland location page says it the same way: entryway mats need daily attention, not weekly. Buildings near MAX stops need the daily rotation most.

Mat length does the work, not rotation alone. A 3-foot mat rotated daily still passes most of the water and grit onto the finished floor behind it. ANSI/NFSI B101.6 is the standard covering selection, installation, inspection and maintenance of commercial entrance matting. RKA runs a scraper mat outside the door and a wiper mat inside, sized to the door width and the traffic, and rotates both each visit.

A curled or loose mat edge is a trip hazard. The crew logs it the same visit and sends the note to you. Commercial floor cleaning Portland buildings need in winter starts at the mat, not at the mop bucket.

Strip and wax in September, not in November

Our commercial cleaning page states the rule. Fall is the worst season for buildup, so we recommend the annual strip and wax in September, before the rains set in. Portland’s humidity slows wax cure, so the crew brings air movers and dehumidifiers to the job.

VCT gets 3 to 5 coats of finish, an annual strip and quarterly buffing. Ceramic tile gets grout restoration and a sealer. Polished concrete gets a sealer. Commercial hardwood gets pH-neutral products. Low-VOC, Green Seal-certified finishes are available for buildings with air quality requirements.

If the building missed September, book the walkthrough anyway. RKA will check the finish and send a written quote for the work it needs. See hard floor care for each floor type.

How we set the price for lobby floor care

RKA gives no price over the phone. RKA walks the building first, about 20 minutes, then sends a written quote. RKA sets the price from square footage, business type and cleaning frequency.

For a lobby, 6 items set the number:

• Lobby square footage.
• Number of entries.
• Visits per week.
• Floor type: VCT, stone, polished concrete or carpet.
• Mat sets, and who supplies them.
• Periodic work: whether the buff, scrub and recoat sit inside the monthly price or on a separate line.

3 things raise the number: an entry next to a MAX stop, a 7-day apartment lobby, and a carpet transition zone that needs extraction. A floor that missed its September strip and wax also raises it.

The quote includes labor, supplies, equipment and insurance. There are no hidden fees and no introductory rate that rises later. Recurring work runs on a 12-month rate lock. If RKA misses a visit, or fails to respond to a flagged issue by the next business day and re-clean it at no charge, you can cancel on 30 days’ notice with no fee.

For a range, the Portland cleaning rates guide lists $0.07 to $0.20 per square foot per month at roughly weekly service for recurring janitorial. Frequency scales it. It also lists $35 to $85 per hour per technician. If you send the work out to bid, put floor care in the bid scope as its own line. Then each bidder prices the same job.

What you get after each visit

Every RKA account runs under the CleanAssure Standard: a dedicated crew, documented SOPs, digital quality reporting, and a satisfaction guarantee with a same-day or next-business-day response.

After each lobby visit, the account manager receives:

• A digital checklist for that visit, with each task marked done.
• Timestamped photos of the entry, the lobby floor and the mat station.
• A note of each maintenance issue: a loose mat edge, a cracked tile, standing water, or a door sweep that lets water in.
• The check-in and check-out log for the crew.

If an item fails your inspection, tell RKA. You get a same-day or next-business-day response, and the crew re-cleans the area at no charge. Read how the satisfaction guarantee works. A missed visit shows up the same night in the check-in log.

Apartment lobbies and office lobbies carry a legal duty

For apartments, ORS 90.320 puts the lobby inside the landlord’s duty. Subsection (1)(f) covers “all areas under control of the landlord”. It requires them “kept in every part safe for normal and reasonably foreseeable uses, clean, sanitary”. A wet lobby also costs leases. 1 vacant 1-bedroom in a Portland apartment building costs about $1,400 a month in lost rent, on Zumper’s September 2026 figure. Read what Oregon law says about common areas.

For offices, Oregon OSHA adopts the federal walking-working surfaces rule, 29 CFR 1910.22, under OAR 437-002-0020 in Division 2, Subdivision D. The rule requires each employer to keep walking-working surfaces clean, orderly and sanitary, and free of hazards such as leaks, spills, snow and ice.

The visit photos and the maintenance log are your record that you met the duty. RKA carries general liability insurance at $1 million per occurrence and $2 million aggregate, and RKA is bonded. RKA sends a Certificate of Insurance on request. Read more on proof of insurance.
