Commercial Building Winter Maintenance: Is Your Property Ready for Winter Weather?

Winter building problems rarely begin with the first snowfall.

Many of the conditions that create headaches during winter are already developing in late summer and early fall: clogged drainage systems, deteriorating sealants, dirty glass, worn exterior surfaces, standing water, and maintenance projects that have been postponed one season too long.

Once temperatures drop, those existing conditions may become more difficult to address.

That’s why commercial building winter maintenance should begin before winter arrives.

For property managers and facility teams, fall provides an important opportunity to inspect the exterior, complete seasonal cleaning, address appropriate maintenance concerns, and identify conditions that require further evaluation.

The goal isn’t simply to prepare for snow.

It’s to send the entire property into winter in the best condition possible.

Why Commercial Winter Preparation Starts in the Fall

Commercial buildings are exposed to changing conditions throughout the year.

Rain, UV exposure, wind, pollution, biological growth, dirt, mineral deposits, and normal material aging all affect exterior surfaces. By late summer, months of exposure may have left behind buildup or revealed areas that deserve attention.

Then fall adds leaves and seasonal debris.

Winter follows with freezing temperatures, snow, ice, road salt, deicing materials, and repeated freeze-thaw cycles in many parts of the country.

Waiting until then to evaluate the property limits your options.

Fall gives facility teams time to identify what needs to be cleaned, what needs routine maintenance, what should be monitored, and what requires evaluation by an appropriate building professional.

1. Clear Gutters and Roof Drains Before Leaves Accumulate

Water management should be near the top of any commercial property’s winter preparation list.

Gutters, downspouts, roof drains, scuppers, and exterior drainage systems are designed to move water away from areas where it shouldn’t collect.

Leaves and debris can interfere with that process.

A drainage system that is partially obstructed in September may become completely clogged as leaves continue to fall.

What Property Managers Should Check

Before winter, inspect accessible drainage areas for:

• Leaves and organic debris
• Dirt and sediment
• Obstructed gutters
• Clogged downspouts
• Blocked roof drains
• Debris around scuppers
• Standing water
• Evidence of previous overflow
• Areas where water repeatedly collects

Pay attention to the entire drainage path rather than only the drain itself.

Where does the water come from?

Where is it supposed to go?

Where does it actually collect?

Repeated standing water or overflow may indicate a condition that requires additional investigation.

Why Drainage Matters Even More During Winter

Once temperatures begin dropping below freezing, water accumulation introduces another concern: ice.

Water that doesn’t drain appropriately can freeze on walking surfaces or in other areas of the property.

Snowmelt also needs somewhere to go.

Clearing drainage systems in the fall doesn’t guarantee that winter drainage problems won’t occur, but it eliminates one very preventable cause: accumulated seasonal debris.

2. Inspect the Building Exterior for Cracks, Failed Sealants and Potential Water Entry Points

Your building envelope spends the entire year protecting interior spaces from exterior conditions.

Fall is an ideal time to walk the property and look for visible changes.

This doesn’t need to be a technical building-envelope inspection. Property managers can begin with a visual assessment and document anything that appears different, deteriorated, or concerning.

Exterior Conditions to Look For

• Cracked or deteriorating sealants
• Gaps around windows or exterior joints
• Visible cracks in exterior surfaces
• Loose panels or components
• Missing or deteriorated materials
• Recurring water stains
• Rust or oxidation runoff
• Biological growth
• Areas of persistent moisture
• Unusual façade discoloration

Take photographs and record the exact location of anything unusual.

If a condition involves possible structural issues, water intrusion, or building-envelope failure, have it evaluated by an appropriately qualified professional.

Don’t Ignore Small Changes

A small exterior condition doesn’t automatically indicate a major building problem.

But it is useful information.

If a crack, stain, or deteriorating joint is documented this fall, you can compare it during future inspections.

Has it changed?

Is the staining spreading?

Does moisture continue to appear in the same area?

Documentation turns a one-time observation into useful maintenance history.

3. Clean Commercial Glass Before Shorter Daylight Hours Arrive

Fall window cleaning isn’t only about curb appeal.

Clean glass can improve the appearance of a commercial property while maximizing available natural light as daylight hours become shorter.

Summer can leave exterior windows covered with:

• Dirt and dust
• Pollen
• Pollution
• Hard water deposits
• Mineral buildup
• Irrigation overspray
• Bird activity
• Construction residue
• Oxidation runoff

Routine commercial window cleaning removes normal surface contamination and gives property teams a clearer view of the condition of the glass and surrounding components.

Look Beyond “Dirty Windows”

Pay attention to glass that remains cloudy, stained, or discolored after routine cleaning.

Persistent hard water deposits, mineral staining, or oxidation runoff may require commercial glass restoration rather than standard window cleaning.

Addressing these conditions earlier can provide more options than allowing them to remain on the glass through another season.

For high-rise and multi-story buildings, professional window cleaning also puts trained technicians in proximity to exterior areas that may rarely be observed closely from the ground.

4. Prepare Sidewalks and Entrances for Changing Weather

Entrances and sidewalks experience some of the heaviest pedestrian traffic on a commercial property.

They are also directly exposed to rain, falling leaves, snow, ice, dirt, and winter deicing products.

Before winter arrives, walk all primary pedestrian routes.

Inspect:

• Main entrances
• Secondary entrances
• Sidewalks
• Steps
• Ramps
• Loading areas
• Curbs
• Exterior drains
• Building overhangs
• Entry glass
• High-traffic transition areas

Look for dirt, biological growth, staining, debris, standing water, and other visible conditions.

Commercial pressure washing and soft washing can help remove seasonal buildup from appropriate exterior surfaces before winter.

Cleaning these areas in advance also gives property teams a better opportunity to observe the underlying condition of walking surfaces before snow and ice begin covering them.

5. Don’t Forget the Parking Structure

Parking garages experience a significant change when winter arrives.

Vehicles begin bringing moisture, road salt, deicing chemicals, slush, dirt, and road debris into the structure.

If the garage already contains months of accumulated dirt and contamination, another winter simply adds to the buildup.

Fall Parking Garage Checklist

Before colder weather arrives:

• Remove accumulated dirt and debris
• Inspect drains for obvious obstructions
• Look for standing water
• Check corners and low-traffic areas
• Review pedestrian walkways
• Inspect stairwells
• Check entrances and exits
• Look for oil and vehicle-fluid staining
• Document visible cracks, leaks, spalling, or other conditions requiring professional evaluation

A planned parking garage cleaning can help reset the structure before another season of winter contamination begins.

It also makes existing surface conditions easier to observe.

6. Address Exterior Surface Buildup Before Winter

Exterior façades collect contamination gradually.

Pollution, biological growth, dirt, bird activity, mineral deposits, rust staining, and environmental residue can remain on exterior surfaces season after season.

Depending on the building material and condition, professional façade cleaning, building washing, pressure washing, or soft washing may be appropriate.

Fall is a useful time to assess these surfaces because weather conditions may still allow exterior work to be completed before winter limits scheduling options.

Pay particular attention to areas with recurring buildup.

If staining repeatedly returns to the same location, the pattern itself may be worth investigating.

7. Review Roof Anchors and Exterior Access Systems

If your property uses permanent roof anchors or other façade access equipment, don’t wait until exterior work is scheduled to determine whether required inspections are current.

Exterior access systems are critical to safely completing work on many multi-story and high-rise buildings.

Including roof anchor inspection and certification in the property’s maintenance calendar can help prevent scheduling delays when window cleaning, façade maintenance, or other exterior services are needed.

Fall maintenance planning is a good opportunity to review inspection records and determine whether any upcoming requirements should be incorporated into the building’s maintenance schedule.

8. Complete Exterior Maintenance While Conditions Are Still Favorable

One of the simplest reasons to handle exterior maintenance in fall is flexibility.

Once winter weather arrives, exterior work may be affected by:

• Freezing temperatures
• Snow
• Ice
• High winds
• Shorter daylight hours
• Unsafe surface conditions
• Limited scheduling windows

Waiting doesn’t necessarily make the project disappear.

It may simply make it harder to complete.

Property managers who review maintenance needs early have more time to prioritize projects and coordinate appropriate service before weather becomes a limiting factor.

Your Pre-Winter Commercial Property Checklist

Before winter arrives, walk your property and review these areas:

• Clear gutters and downspouts.
• Check accessible roof drains and scuppers.
• Look for standing water or recurring drainage problems.
• Inspect exterior sealants and joints for visible deterioration.
• Document cracks, loose components, or unusual façade conditions.
• Check exterior glass for dirt, hard water, and mineral deposits.
• Identify glass that may require restoration.
• Clean entrances and high-traffic exterior surfaces.
• Inspect sidewalks, steps, ramps, and pedestrian areas.
• Review exterior drains near entrances.
• Inspect parking garage drains and traffic areas.
• Address accumulated parking structure debris.
• Review façade surfaces for heavy buildup or staining.
• Confirm applicable roof anchor inspections are current.
• Photograph and document conditions that need monitoring.
• Schedule appropriate exterior maintenance before winter conditions arrive.

Create a Winter-Ready Maintenance Plan

After completing the inspection, divide your findings into four categories.

Address Now

Conditions requiring immediate attention or evaluation.

Complete Before Winter

Cleaning and routine maintenance that should ideally occur while weather conditions remain favorable.

Monitor

Items that don’t currently require action but should be documented and reviewed again.

Budget for Later

Larger restoration, repair, or capital projects that should be incorporated into future planning.

This prevents every observation from becoming an emergency while ensuring important items aren’t forgotten.

Winter Preparation Looks Different Across a National Portfolio

Winter readiness isn’t identical in every market.

A commercial property in Milwaukee or Chicago faces different seasonal conditions than a building in Phoenix or West Palm Beach.

Even properties in warmer climates can experience seasonal rainfall, storms, environmental buildup, drainage concerns, and changing maintenance needs.

For multi-location portfolios, the goal shouldn’t necessarily be an identical maintenance schedule at every property.

It should be a consistent process for evaluating each property’s needs and scheduling the appropriate services for its location, building materials, environmental exposure, and operating requirements.
