Commercial Exterior Cleaning Maintenance Guide
How Often Does Your Spokane Property Actually Need to Be Cleaned?
Commercial exterior cleaning maintenance is one of those topics we get asked about constantly. It’s always “how often should this happen?”
The answer is more often than you would think and at least twice a year as an absolute minimum for most commercial properties. But the real answer depends on three things. The foot traffic your property sees, the type of business you operate, and specifically what surface is being cleaned.
We see properties every week that have been putting off professional cleaning for years. The dirt and grime have been there so long they start to look normal. There is no judgment in that. We understand it. Getting started is the hardest part and a dirty project is genuinely satisfying for both of us when you see what it looks like clean.
For me, I do not like going to the dentist. Not because I have ever had a cavity. It is just sitting down and staying still that is the hard part. Getting a commercial property cleaned is similar. The anticipation is worse than the reality and the result makes you wonder why you waited.
Here is our maintenance guide by property type.
Why Commercial Exterior Maintenance Matters in Spokane
Downtown Spokane is a $1.63 billion commercial real estate market with 4.43 million leasable square feet and 8,700 employees working in the Business Improvement District according to the Downtown Spokane Partnership 2026 Q2 Report. The district generates more than $246 million in annual sales tax and attracts 2.4 million visitors each year.
That economic activity creates a specific competitive environment for commercial property owners and managers. With 26.9 percent office vacancy and 10.3 percent retail vacancy in downtown Spokane properties are competing for tenants and customers in a market with real alternatives. A well-maintained exterior is one of the most visible signals of professional property management. An unmaintained one is one of the fastest ways to lose a tenant comparison.
The guide below covers recommended cleaning frequencies for every major commercial property type in the Spokane market. Every recommendation is based on real cleaning experience across Spokane properties not generic national guidelines that do not account for Spokane’s specific climate, foot traffic patterns, and seasonal challenges.
Restaurants and Food Service Properties
Food service properties have the most demanding exterior cleaning requirements of any commercial property type. The combination of cooking grease, food waste, heavy foot traffic, and the specific health and inspection requirements that govern food service businesses means exterior cleaning is not optional maintenance. It is operational necessity.
Dumpster Pad | Quarterly
Quarterly is the minimum for any active restaurant or food service operation. Monthly is better for high volume locations. Dumpster pads accumulate grease, food waste, and biological material that creates odor and appearance problems that get worse every week they are not addressed. Also when staff come in and out from taking trash out or enjoying the employee lounge that grease gets tracked inside. A quarterly maintenance schedule prevents the pad from reaching a condition that requires restoration cleaning rather than maintenance cleaning. Restoration cleaning costs more and takes longer.
Windows | Monthly
Restaurant windows accumulate cooking grease, exhaust residue, and fingerprints from customers and staff that make them look perpetually dirty within weeks of cleaning. A monthly interior and exterior window cleaning route keeps the storefront looking the way it should and prevents grease buildup from bonding permanently to the glass surface.
Building Exterior | Annually or Bi-Annually
Washing the building exterior at least once a year keeps algae mildew and urban grime from establishing on the surface. Restaurants near trees or busy roads benefit from a bi-annual cleaning plan because tree coverage and vehicle exhaust accelerate buildup on siding and building surfaces.
Warehouses and Industrial Buildings
Large warehouses and industrial buildings have different cleaning requirements than customer facing commercial properties. The surfaces are more durable, the foot traffic is different, and the cleaning schedule can be more relaxed without significant consequence.
Building Exterior | Annually
Once a year is typically fine for most warehouse and industrial exteriors. Schedule it in summer to avoid the spring and fall rush when everyone else is trying to get on the schedule simultaneously. A summer cleaning gives you the best weather conditions and the most scheduling flexibility.
Windows | Twice Annually
Warehouse windows benefit from twice annual cleaning even when interior cleaning is not required for most of the building. The main entry windows and any customer or visitor facing glazing should be cleaned at least twice a year. Interior window cleaning on just the main entryway is typically all that is needed for the rest of the building.
Parking Lot and Concrete | Annually
Warehouse parking lots accumulate oil contamination from delivery vehicles and heavy equipment that benefits from annual hot water treatment. Letting oil leaks sit through multiple seasons makes removal more difficult and results begin to diminish too.
Apartment Complexes and Multi-Family Properties
Apartment complexes and multi-family properties balance resident satisfaction with operational efficiency. The goal is consistent maintenance that keeps properties competitive in the rental market without constant disruption to the people who live there.
Building Exterior | Annually
Once a year is a great option for most apartment complexes. It minimizes disruption to residents, keeps the exterior maintenance checklist current, and prevents the property from reaching a condition where a prospective tenant pulls up and drives away before they even get out of the car.
Window Cleaning | Annually or With Building Wash
Exterior window cleaning can be added to the same visit as the building exterior washing for efficiency. Scheduling both services together reduces the number of times equipment is mobilized and in most cases reduces the combined cost compared to scheduling separately.
Dumpster Enclosures | Quarterly
Apartment complex dumpster enclosures are some of the most neglected surfaces on any rental property and the ones that generate the most tenant complaints. Quarterly cleaning keeps the enclosure from becoming a property management headache and demonstrates to tenants that the property is being actively maintained.
Hotels and Hospitality Properties
Hotels never fully stop. The cleaning schedule has to work around occupancy patterns, event calendars, and the reality that guest areas cannot be wet or disrupted during peak arrival and departure windows.
Building Exterior | Annually or Bi-Annually
Most Spokane hotels benefit from at least annual exterior washing. Downtown properties near high vehicle traffic and urban exhaust accumulation benefit from bi-annual cleaning. Schedule cleaning during low occupancy periods and coordinate directly with operations to avoid conflict with event calendars. Bloomsday and Hoopfest in Spokane create occupancy spikes that close scheduling windows fast. Book before those events not after.
Entry and Sidewalks | Quarterly
Hotel entry areas, porte cocheres, and adjacent sidewalks see constant foot traffic and benefit from quarterly cleaning to keep the guest arrival experience consistent. Gum removal, organic staining, and exhaust residue accumulate quickly on surfaces that never get a break from use.
Windows | Monthly or Quarterly
Street facing hotel windows benefit from monthly exterior cleaning in high traffic downtown locations. Property facing windows and upper floor glazing can typically be maintained quarterly. A monthly route for the most visible windows and a quarterly schedule for the rest balances cost with appearance standards.
Parking Lots | Twice Annually
Spring and fall parking lot cleaning removes the winter accumulation and the summer contamination that comes from the spike in event and tourism traffic during peak Spokane season.
Colleges and Educational Facilities
Educational facilities have scheduling constraints that no other commercial property type deals with. The academic calendar determines what is possible and when.
Building Exterior | Annually
Summer break is the ideal window for major exterior cleaning on college and university campuses. The property is as empty as it will get, facilities access is straightforward, and the work can happen without routing around thousands of students and their schedules.
Sidewalks and High Traffic Concrete | Twice Annually
Campus sidewalks take more foot traffic than almost any commercial surface. Spring cleaning after the academic year removes the winter accumulation. Fall cleaning before the new academic year starts gives incoming students and prospective visitors the best first impression of the campus.
Dumpster Pads and Dining Areas | Quarterly
Campus food service dumpster pads require the same quarterly attention as any restaurant operation. The volume is higher and the compliance requirements around health and environmental standards make regular cleaning a necessity rather than a preference.
Windows | Twice Annually
Natural light matters in educational environments. Twice annual exterior window cleaning on academic buildings and student housing keeps light transmission consistent through both semesters.
Medical Buildings and Healthcare Facilities
Medical facilities have cleanliness standards that extend beyond aesthetics. Patient populations notice the exterior condition of a facility before they ever walk through the door and regulatory oversight creates documentation requirements that other commercial property types do not face.
Building Exterior | Twice Annually
Bi-annual exterior washing for most medical facilities. Spring cleaning after winter and fall cleaning before the winter season keeps the building looking the way a healthcare facility should look year round.
Entrance Walkways and Accessible Routes | Quarterly
The most safety critical surfaces on any medical property. Algae and organic growth on walkways creates genuine slip hazards for patients with mobility challenges. Quarterly cleaning prevents growth from establishing and keeps the most visible patient facing surface in consistently good condition.
Windows | Monthly or Quarterly
Medical office buildings and clinic windows benefit from monthly exterior cleaning in high traffic locations. Natural light in patient areas and waiting rooms affects the patient experience in ways that dirty windows undermine regardless of how clean the interior is.
Parking Lots | Twice Annually
Medical facility parking lots see continuous vehicle traffic. Twice annual hot water cleaning removes petroleum contamination and keeps the surface the patient walks across looking as maintained as the facility it leads to.
Gas Stations and Fuel Service Facilities
Gas stations are among the highest demand exterior cleaning properties because the contamination profile is aggressive and the regulatory environment around petroleum runoff is specific.
Fuel Island Concrete | Quarterly
Quarterly is the minimum for fuel island concrete. Monthly is better for high volume locations. Oil and gas bonds into concrete over time and becomes significantly harder and more expensive to remove as it accumulates through multiple seasons. Quarterly maintenance keeps the contamination manageable and the cleaning cost predictable.
Canopy and Bonnets | Twice Annually
Spring and fall canopy cleaning removes cobwebs, exhaust residue, and the general buildup that makes even a well maintained station look neglected from the road.
Entry Sidewalks and Convenience Store Windows | Monthly
Monthly interior and exterior window cleaning and monthly sidewalk cleaning keeps the customer facing surfaces looking the way they should at a high traffic commercial location.
The General Rule for Every Commercial Property
If you are not sure where your property falls here is the simple version.
Customer facing surfaces that people see and touch daily need more frequent attention than building exteriors that accumulate slowly over seasons. Surfaces near grease, food waste, or petroleum contamination need more frequent cleaning than surfaces that only see weather and foot traffic. Properties near trees or busy roads accumulate faster than properties in less exposed locations.

Bundling Services for Efficiency and Cost
The most efficient commercial cleaning programs bundle related services into the same visit rather than scheduling each one separately.
Building exterior washing and exterior window cleaning together. One mobilization, one visit, both services completed before the crew leaves. In most cases bundling reduces the combined cost compared to scheduling separately.
Dumpster pad cleaning and parking lot cleaning together. Both require hot water equipment. One setup, two surfaces cleaned in the same visit.
Roof cleaning and gutter clearing together. We are already up there. Adding gutter clearing to a roof cleaning visit is a fraction of what a separate gutter cleaning visit costs.
Ask about bundling when you call for a quote. We build cleaning programs that make sense for your operation not ones that maximize our visit count.
Getting Started When It Has Been a While
We see properties every week where the cleaning has been deferred long enough that the dirt looks normal. The algae on the north face of the building blends into the background. The dumpster pad has been that way for years. The windows have not been professionally cleaned since the previous tenant.
There is no judgment. Getting started is the hard part. The result makes you wonder why you waited.
