Most homeowners know they should clean their home’s exterior — but very few know how often they should actually do it. The answer in Texas is different from most other parts of the country, and understanding why helps you protect your home and budget maintenance the right way.
The Short Answer
For most homes in Arlington and the DFW area, here’s the basic schedule:
- Home exterior / siding: Once per year
- Gutters: Twice per year (spring and fall)
- Driveway and concrete: Every 1–2 years
- Roof: Every 2–3 years
Why is this more frequent than what you might read in general home maintenance advice? Because Texas climate is harder on home exteriors than most.
Why Texas Homes Need More Frequent Cleaning
Humidity. The Dallas-Fort Worth area doesn’t have the extreme humidity of coastal states, but it’s humid enough — particularly from late spring through fall — to create ideal conditions for mold, mildew, and algae growth on exterior surfaces. These organisms need only moisture, warmth, and a surface to cling to. Your home’s siding, roof, and concrete provide all three.
Heat. Texas summers bake organic matter onto surfaces. Pollen, dust, algae, and bird waste bond more aggressively to surfaces at high temperatures and become harder to remove the longer they’re left.
Pollen season. North Texas has one of the most intense pollen seasons in the country, running from late February through April. The yellow-green film that coats everything during this period — your car, your porch furniture, your siding — is not just cosmetic. When moisture is added, pollen becomes a food source for mold and algae.
Storm activity. Spring storm season in the DFW area brings wind, rain, and debris that coats and stains exterior surfaces. Gutters fill up with organic matter. Algae gets a fresh water source to accelerate growth.
Recommended Frequency by Surface
Home Exterior (Siding, Brick, Stucco)
Frequency: Once per year
Annual house washing removes mold, mildew, pollen, algae, and general grime before it has the chance to etch into surfaces or get behind them. For most Arlington homes, spring cleaning — after pollen season wraps up in May — is the ideal timing.
If you have significant tree coverage shading the north or west sides of your home, you may notice faster mold and algae growth in those areas. Homes with heavy canopy nearby sometimes benefit from cleaning every 9 to 10 months on shaded elevations.
Gutters
Frequency: Twice per year — spring and fall
Spring cleaning (April–May) clears out the pollen and debris accumulated over winter and early spring. Fall cleaning (October–November) removes leaf buildup after trees drop, so your gutters are clear heading into winter rain season.
Homes with heavy tree coverage — particularly large oaks or pines — may benefit from 3 or 4 cleanings per year. When gutters fill up and overflow, the water damage to fascia boards, foundations, and landscaping happens quickly.
Driveway and Concrete Surfaces
Frequency: Every 1–2 years
Concrete driveways and patios don’t need annual cleaning unless they have heavy vehicle traffic, significant oil drips, or large shaded areas that develop algae quickly. For most Arlington homeowners, every other year is sufficient to keep concrete looking good and prevent deep staining.
If you’re planning to sell your home or want your property looking its best for a specific reason, annual driveway cleaning makes sense regardless of the standard maintenance schedule.
Roof
Frequency: Every 2–3 years
Because proper roof cleaning uses soft washing (not pressure washing), it’s gentler on the surface and the results last longer. Most Arlington-area roofs develop visible algae growth and black streaking on a 2 to 3 year cycle.
Homes with large trees hanging over the roof, or north-facing rooflines that stay shaded and damp, may develop growth faster. If you can see dark streaks or green patches from the ground, it’s time to schedule a cleaning regardless of when the last one was done.
Signs It’s Time to Clean Sooner
Beyond the regular schedule, a few visual cues tell you it’s time to book a cleaning regardless of timing:
- Green or black growth on siding, particularly near the roofline or foundation
- Dark streaking on your roof shingles
- Gutters overflowing or visibly full of debris
- Driveway looking significantly darker or stained in vehicle parking areas
- A general dullness or discoloration on your home’s exterior
- You’re preparing to list your home for sale
The Cost of Waiting Too Long
Every year you skip your home’s exterior cleaning is a year that mold, algae, and grime are working deeper into your surfaces. What costs $350 to clean now can cost considerably more after years of neglect — both in cleaning fees and potential surface repair or replacement.
The most expensive exterior cleaning job we do at Stegmeier Pressure Washing is always on homes that have gone 4 or 5 years without any maintenance. The most affordable jobs — with the best results — are on homes that stay on a regular annual schedule.
