The Exterior Building Maintenance Year, Season by Season
Mountain cedar in Central Texas begins producing pollen in mid-December, with the season running into early March and peaking in mid-January, according to Texas A&M, and it hits hardest in the Hill Country west of Interstate 35, where Ashe juniper grows thick. For anyone responsible for exterior building maintenance, that date matters more than New Year's Day. It means the first soiling event of the year lands on your glass, ledges and solar panels before the annual plan has even been approved, and every season after it brings its own predictable problem.
The calendar below follows that year from one cedar season to the next, for facility teams running commercial buildings in Texas and Oklahoma.
December to February: Pollen Arrives While the Plan Is Still a Draft
Cedar pollen is fine and yellow, and it settles everywhere. On dry days it sits as a dull film on glass and window ledges. The first rain turns it into streaks that run down from every sill. Oklahoma gets a different winter, with ice, freeze-thaw cycles and strong winds that push dirt onto exposed elevations, but the effect on the building is similar: the outside looks tired by February.
Winter is mostly an inspection and booking season. After hard freezes, walk the exterior for new cracks in stucco and masonry, displaced flashing and any leaks tenants report inside. Confirm that the responsible trade has winterized exterior water connections, irrigation and backflow assemblies. Keep shaded concrete at entries under watch for slick buildup.
Cleaning can still happen on mild, dry days, as long as wash water will not freeze on walking surfaces, so winter dates need to stay flexible. The most useful thing to do in January is book the spring visits while contractors' calendars are still open.
March to May: The Busiest Season for the Outside of the Building
Cedar gives way to oak and other tree pollen, and both states move into severe storm season, with high winds, heavy rain and hail. This is when most of the year's exterior work should land.
Wash the facade, then the glass
Make the first full clean of the year cover the walls and windows together, in that order. Removing pollen and grime from the facade first means there is nothing left to run onto clean glass at the next shower, so the windows stay presentable well into summer. Stucco, EIFS, painted surfaces and masonry call for low-pressure soft washing, and the glass finishes with purified water so it dries without spots.
Look at roofs and drains after winter
Check drains and scuppers for debris, and look for open seams, loose flashing and ponding. Membrane damage goes to the roofing contractor before any cleaning is booked. Our commercial roof maintenance guide walks through what to look for.
Treat hail and wind as their own trigger
Severe weather does not wait for the next scheduled visit, so the plan should not either. After a hail or wind event, document what you can see from safe vantage points, send roof, glazing and solar damage to qualified specialists, and keep the photos with the repair records. A clean roof or array also makes damage easier to see.
June to August: Heat and UV Work on Sealants and Finishes
Long hours of UV and surface temperatures far above the air temperature dry out caulking, fade coatings and make midday exterior work slower and harder on crews. Summer is a season for inspection, with any heavy cleaning kept out of the afternoon heat.
On sun-facing elevations, look for sealant joints that are splitting, pulling away or hardening, and send failures to a sealant contractor. Watch painted metal and coated panels for chalking or fading, which may call for coating maintenance rather than another wash. Check lower glass for hard water spotting where irrigation runs more often in the heat, and have sprinkler heads that hit the building adjusted.
Solar arrays can lose their shine quickly after a dry spell, with dust, leftover pollen and bird droppings building up. Our roof and solar cleaning rinses panel glass with purified water and puts no foot traffic on the roof.
Any summer cleaning works best early. Cooler walls and glass stop solutions drying too fast, crews avoid the worst heat, and flexible operating hours keep the work clear of tenants arriving mid-morning.
September to November: Water Paths and Holiday Traffic
Fall is about getting water off the building. Leaves, seed pods and debris left from summer storms collect in gutters, roof drains and scuppers right before the wetter months. Clear them, then check that the outlets at ground level are open too.
After the first good rain, walk the site and note where water overflows, ponds on walks or runs across entries. Clean entrances, loading docks and dumpster pads before holiday foot traffic picks up, and schedule the year's second semi-annual window visit (or the fourth quarterly one) so the building looks its best into December. Then sit down with the year's records and set next year's budget around what got dirty fastest.
A Year-Round Facility Maintenance Checklist
Organize the checklist by part of the building, with each item tied to a season or a trigger:
Glass and frames: cleaned quarterly or at least semi-annually, checked for streaking, spotting and failing seals after pollen season and storms.
Facade and joints: soft washed every one to three years (most commercial sites land on yearly or every other year), with spring and summer checks for organic growth, cracks and failed sealant.
Roof and penetrations: inspected in spring and fall and after significant storms, cleaned on debris and growth.
Solar arrays: cleaned on visible soiling and the array's performance data.
Gutters and drains: cleared in fall and after heavy debris or storms.
Walkways and parking: cleaned by traffic, checked in freeze season for slick or uneven surfaces.
Loading and service areas: cleaned around delivery schedules, with runoff controls for grease and oil.
Give every line an owner and a way to close it out, such as a dated photo, a contractor's report or a note that the item is being monitored.
Grouping the Year Into Fewer Visits
The calendar gets much easier to run when tasks that fall due together share a visit. A spring visit covering facade, glass and entries means one round of tenant notices, one safety setup and one day of disruption instead of three. Time those visits for the quietest hours of the building's week, and drone methods help further because crews work from the ground, walkways outside the active zone stay open and nothing heavy sits on the landscaping. Our exterior cleaning services can be set up as one recurring program, and we offer discounts both for bundling services and for committing to a schedule.
Turning the Calendar Into Next Year's Budget
Put the fixed dates in first: the spring facade and glass visit, the second window visit in fall, and the spring and fall roof inspections.
Add the triggers below them, with a named person who acts after hail, high wind or a heavy debris event.
Mark the elevations that soiled fastest this year and give them a shorter cycle than the rest of the building.
Book the spring work in January, before pollen season fills everyone's calendar.
Frequently Asked Questions
When should a Central Texas building get its facade soft washed?
Many properties plan it for late winter or spring, once the heaviest cedar pollen has passed. That clears the season's buildup and readies the building for summer, though shaded or damp elevations may need attention at other times of year.
Does exterior work stop during an Oklahoma winter?
Not entirely. Inspections, drain checks and planning carry on through the cold months, and cleaning moves to mild, dry days. Late-winter wind often leaves red dirt on exposed walls just before the first wash of the year, so it pays to have spring dates locked in.
Should exterior and interior work share one building maintenance schedule?
Yes, where possible. Lobby floor refinishing right after an entrance wash, or rooftop equipment service the week before a roof clean, saves trips and avoids one trade undoing another. Keeping both on one calendar, owned by one person, makes those overlaps easy to spot.
How far ahead should tenants hear about exterior work?
A few days' notice is the usual courtesy, with dates, times, affected entrances or parking and a contact for questions. Grouping the work into fewer visits also means fewer notices in tenants' inboxes.
What should change in the plan after a hail season?
Move a roof and solar inspection up the list, add a check of glazing and skylights on the storm-facing side, and review whether any damaged sealant or flashing needs repair before the next facade wash. Feed whatever the inspections find into next year's budget lines.
