If you have lived in the Temple-Killeen area for more than a year, you have already seen what Bell County weather does to a home exterior. Spring cedar pollen coats every surface in yellow. Summer brings 100-degree heat, daily humidity, and the occasional pop-up storm. Fall drops leaves and mountain cedar pollen all over again. Winter brings the freezes and the cycle restarts.
The result is that homes in Temple, Killeen, Belton, Harker Heights, and Salado need pressure washing more often than national averages would suggest. Here is the schedule we use with our customers, broken down by surface, after seven years of work in this exact climate.
The Quick Answer for Most Bell County Homes
For a typical single-family home in Temple, Killeen, or the surrounding area:
- Driveway and concrete: Every 12 months
- House siding: Every 12 to 18 months
- Roof soft wash: Every 18 to 24 months
- Wood fence: Every 12 to 18 months
- Wood deck: Every 12 months
- Gutters: Twice a year (after pollen season and after leaf drop)
Properties with mature live oaks, properties out near Lake Belton, and older homes in central Temple need the more frequent end of these ranges. Newer construction in Wildflower, Yowell Ranch, or the Killeen subdivisions can usually stretch to the longer side.
Why Bell County Is Tougher Than National Averages Suggest
Cedar Pollen Season
From late December through February, mountain cedar (Ashe juniper) releases massive amounts of pollen across central Texas. Temple sits in the heart of cedar country. The pollen coats every horizontal surface, sticks in cracks and crevices, and feeds mold growth for months afterward. We covered this in detail in our cedar pollen pressure washing guide. The short version: a thick post-cedar cleaning in March is non-negotiable for most Temple-Killeen homes.
Red Clay Soil
The soil across most of Bell County is iron-rich red clay. Foot traffic, pet paws, and tire treads carry that clay onto driveways, sidewalks, porches, and patios. Once it dries it leaves rust-colored stains that get harder to remove with each passing month. Annual cleaning prevents permanent staining.
Storm Debris
Bell County averages 60 thunderstorm days per year. Each storm deposits leaves, twigs, dust, and runoff against siding, fences, and concrete. After hail or high-wind events, the damage compounds fast.
Heat and Humidity
Temple summers run 95 to 105 degrees with afternoon humidity in the 60% range. That combination grows mold, mildew, and algae faster than most people realize. The north side of any home in Bell County will develop visible biological growth within 12 months of the last cleaning.
Surface-by-Surface Schedule
Driveways and Concrete: Every 12 Months
Bell County driveways pick up red clay tracks, oil drips, mold from shaded areas, and tire marks. Annual cleaning is the right cadence. Wait longer and the staining starts to set. We've seen Temple driveways that were never cleaned in 5+ years where 80% of the staining could still be removed, but it took us twice the time and twice the cost compared to a routine annual visit.
House Siding: Every 12 to 18 Months
Brick is the most common siding in Temple and Killeen, and it actually holds dirt and mold longer than vinyl or Hardie. The mortar lines collect mildew, the bricks themselves get a dingy cast on the north side. Annual cleaning keeps it crisp. Newer Hardie or vinyl homes can sometimes go 18 months between cleanings.
Roof: Every 18 to 24 Months
Asphalt shingle roofs in Bell County develop the same Gloeocapsa magma bacteria that causes black streaks elsewhere in the country. Our hot, humid summers feed it. A soft wash every 18 to 24 months keeps the roof clean. Importantly, never let anyone pressure wash an asphalt roof. The high pressure strips the protective granules and shortens shingle life by years. Soft wash only.
Wood Fences: Every 12 to 18 Months
Cedar and pine fences in central Texas weather faster than you might expect because of the UV exposure and humidity combination. A soft wash with a wood-safe detergent restores the original color. If you stain or seal after cleaning, you can stretch the cycle to 18 to 24 months.
Decks: Every 12 Months
Decks take direct sun, foot traffic, and the occasional grill grease. Annual cleaning is the minimum. Shaded decks (especially under live oaks) sometimes need cleaning twice a year because mold and mildew colonize them faster.
Gutters: Twice Per Year
Once after cedar pollen season (late February or early March) and once after leaf drop (mid to late November). Clogged gutters cause overflow, which leads to the brown streaks you see running down siding from the roof line.
Properties That Need More Frequent Cleaning
- Homes shaded by mature live oaks or post oaks
- Homes near Lake Belton or Stillhouse Hollow Lake
- Homes in older central Temple neighborhoods (lots of trees, older paint)
- Homes with HOA appearance requirements
- Rental properties or military housing where appearance matters for inspection
- Homes with swimming pools (chlorine + humidity = faster algae growth)
- Homes more than 20 years old
For these properties, twice-a-year cleaning is usually the right answer. We offer maintenance plans that automate the schedule so you don't have to track it yourself.
Best Times of Year to Schedule
Late February to Early April
The single best window. Cedar pollen season is winding down, mountain laurel and live oak pollen are about to start. Cleaning now removes the winter buildup and gives surfaces a clean baseline going into spring.
Late October to Early December
The second-best window. Storm season has wound down, summer heat has eased, and pollen is months away. This is when you address everything that built up during the long Texas summer.
Worst times: July and August (constant heat, brittle vegetation, poor working conditions) and December through January (active cedar pollen season means you'd just need to clean again immediately).
Signs You've Waited Too Long
- Green or black streaks on siding visible from the street
- Roof shingles look dark or stained
- Concrete driveway looks gray instead of white
- Fence has gone from brown to gray
- Cobwebs and bug nests under every eave
- Slippery walkways after rain
- Visible red clay staining on patio or pool deck
- Front door area looks tired and uninviting
Two or more signs means it's time. All the way down the list means you're at least a year overdue.

Frequently Asked Questions
Is once a year really enough for a Temple home?
For a complete property cleaning, yes. The key word is "complete." If you only do the driveway one year and only the house the next, the parts you skip will look two years old when you finally get to them. A full property visit once a year is the minimum.
Can I just rinse my home with a garden hose?
A garden hose maxes out around 50 PSI, which won't remove biological growth that has rooted into pores. It can rinse off loose dirt but won't kill mold or algae. You need either chemistry (soft wash) or pressure (pressure wash) to actually remove the growth.
Should I clean before or after cedar pollen season?
After. Cleaning in November or December is wasted work because cedar pollen will coat everything within weeks. Wait until March, after the worst of cedar season has passed, to do a deep clean.
Do you offer a maintenance plan?
Yes. Brothers Pressure Washing offers annual and bi-annual maintenance plans for Bell County homeowners. We schedule the visits, you don't have to remember. Plans include scheduling priority, locked-in pricing, and discounted rates. Call (254) 555-0319 to set one up.
Do new construction homes need cleaning right away?
Yes. New construction homes typically have construction dust, mortar splatter, paint overspray, and yard debris that should be cleaned within the first few months. We covered this in our new construction pressure washing guide.
What about homes near Lake Belton or Stillhouse Hollow?
Lakefront properties need more frequent cleaning. The constant moisture from the lake increases mold and algae growth, and the boat traffic kicks up additional dirt and water spray. We typically recommend twice-a-year cleaning for lake properties. Read our Lake Belton property maintenance guide for the full breakdown.
