A cleaning contract is only useful if the same scope shows up on the nights you paid for. Contract cleaners from Strong Tower put daily janitorial, weekly cleaning, bi-weekly service, and monthly deep cleans in writing — floors, restrooms, breakrooms, and trash — with a crew lead you can actually call. We serve office buildings, property managers, retail centers, medical facilities, and schools across Portland, Beaverton, Hillsboro, Tigard, Aloha, and Lake Oswego. You are not buying a mystery visit. You are buying a commercial cleaning contractor relationship with a schedule, a checklist, and room for inspections when you want them.

Janitorial contracts and cleaning service agreements should say what happens when you add a floor, change a key code, or pause a suite for a remodel. We price by square footage, frequency, and soil load, then adjust scope in writing when the building changes. Quality inspections run on a cycle so a facilities manager can see that restrooms and entries are actually being done. Cancellation terms and notice periods are in the proposal before you sign, not discovered after a missed week on the route. That is the difference between a route vendor and a partner who stays accountable after month one.

Portland companies looking for contract cleaners usually want one vendor for the nightly clean and a clear path to floor care or disinfection when the building needs it. Strong Tower can hold those services on the same agreement so you are not re-bidding every specialty job that comes up later in the year. Most proposals follow within a day of the site visit, and onboarding is typically inside a week of a signed scope, a key handoff, and a confirmed start date you can put on the calendar. You will have a crew lead name before the first night of service starts.

Questions

What terms are in a janitorial contract?

Cleaning service agreements list frequency, areas, access, price, and how scope changes are approved. Contract cleaners at Strong Tower put cancellation notice in the proposal before you sign so the term is not a surprise.

How do contract cleaners price the work?

Pricing models follow square footage, visits per week, and soil load. A medical suite and a retail center are not the same rate. You get a written number after the walkthrough, not a per-square-foot guess from a web form.

What is your cancellation policy?

Notice periods are stated in the janitorial contract. We do not hide cancellation terms. Ask for them on the proposal, or call 971 516 0787 and we will walk through them before you commit.

Can we change the scope after the contract starts?

Yes. Scope changes — a new suite, fewer visits, added floor care — are written into the cleaning service agreement so both sides are pricing the same work. Contract cleaners should update the checklist, not improvise.

Do you inspect quality on contract accounts?

Yes. Quality inspections run on a set cycle for commercial cleaning contractor accounts. You can walk the site with us or review notes so restrooms, entries, and floors stay on the standard you bought.
