Signs You Need a Residential House Washing Pro in Longmont
Catch these early in Longmont's semi-arid highland climate.
01Visible green or black streaks on sidingThese are often algae or mildew, which thrive in Boulder County's humid mornings. If left untreated, they can cause permanent staining and even damage the siding material.
02Chalky white residue on your hands after touching the sidingThis is oxidation, common on aluminum and vinyl siding in Longmont. It not only looks bad but can also affect paint adhesion if you plan to repaint.
03Dirt splatters on lower walls after rainRain splashing dirt onto your home's exterior is a clear sign that the siding needs cleaning. In Longmont's semi-arid climate, this happens frequently during spring and summer storms.
04Cobwebs and insect nests under eavesSpiders and wasps love to build nests in soffits and fascia. Regular cleaning deters them and keeps your exterior looking tidy.
05Faded or dull exterior paintDirt, mildew, and oxidation can make even recently painted homes look old. A professional wash can restore color and extend the life of your paint job.
06Allergic reactions or musty odors near exterior wallsMold and mildew spores can trigger allergies. If you notice musty smells or increased allergy symptoms, it's time for a professional exterior cleaning.
Longmont problem patterns
Common Residential House Washing Problems in Longmont
The issues we fix most for Longmont homeowners, and why they happen here.
Green algae and mildew streaks on siding
Why it happens In Boulder County's warm, dry summers and low to moderate precipitation, moisture lingers on north-facing walls, giving algae and mildew a perfect place to grow. Longmont's semi-arid highland climate means these growths can spread quickly if not treated early.
Our approach We use a low-pressure soft wash with biodegradable solutions to kill algae and mildew at the root, then rinse gently so your siding stays intact. Our Longmont crews also treat surrounding areas to prevent regrowth.
Dirt and grime buildup from dust and pollen
Why it happens Longmont's dry, windy days carry fine dust and pollen that settle on exterior walls and bond with morning dew. Boulder County's semi-arid conditions make this a year-round issue for many homes.
Our approach We apply a gentle pre-treatment to loosen dirt, then use pressure washing at the correct PSI for your siding material. Our team also cleans soffits, fascia, and trim to remove every trace of buildup.
Oxidation and chalky residue on aluminum siding
Why it happens Aluminum siding oxidizes over time, leaving a chalky film that dulls the finish and streaks when it rains. In Longmont, this is especially common on older homes that haven't been professionally cleaned in years.
Our approach We use a specialized aluminum-safe cleaning solution that removes oxidation without damaging the surface. After treatment, we rinse thoroughly to restore shine and prepare the siding for paint if needed.
Cobwebs, insect nests, and debris under eaves
Why it happens Longmont's warm summers attract spiders and insects that build nests in soffits, fascia, and trim. These areas are often overlooked, leading to unsightly cobwebs and potential pest problems.
Our approach We include soffit, fascia, and trim cleaning in every full exterior wash, using extendable tools to reach high areas safely. Our Longmont crews also clear cobwebs and nests, leaving your home pest-free and clean.

Longmont through the year
Seasonal Residential House Washing Tips for Longmont
How Longmont's semi-arid highland climate changes Residential House Washing needs through the year.
Spring
Spring in Longmont brings low to moderate precipitation and pollen, which can leave your siding streaked and grimy. Algae and mildew start to bloom as temperatures rise.
Tip Schedule a spring wash to remove winter grime and pollen before summer. Check for any winter damage and treat early signs of mold.
Summer
warm, dry summers means intense sun and dry spells, but afternoon thunderstorms can splatter dirt and dust onto your exterior. Oxidation on aluminum siding becomes more visible.
Tip A mid-summer cleaning helps maintain curb appeal and prevents dirt from baking onto siding. Water your landscaping before and after to protect plants.
Fall
Falling leaves and cooler temperatures bring dampness, which can encourage mold growth on north-facing walls. Dust and debris accumulate in soffits and gutters.
Tip Get a fall wash to remove leaf stains and prepare your home for winter. Clear gutters and downspouts to prevent water damage.
Winter
cold, snowy winters brings snow and freezing temperatures, which can freeze dirt and grime onto siding. Ice dams and condensation may cause mildew in shaded areas.
Tip A pre-winter cleaning protects your siding from freeze-thaw damage. If you spot mold, call for a winter-safe soft wash - never use high pressure in freezing temps.
