Why Regular Cleaning & Maintenance Are Essential
Why Coastal Properties Face Unique Risks
- Coastal regions experience higher humidity, salt exposure and baking sun/ultraviolet rays- ideal conditions for biological and chemical degradation.
- Buildings in our area are a to airborne contaminants and moisture, leading to accelerated decay.
Threat #1 – Mildew
What is it?
Mildew is a fungal growth that thrives on damp surfaces, particularly in shaded and humid areas.
It appears as white or gray patches on siding, roofs, and decks.
Scientific Data & Damage:
Mildew feeds on organic materials, causing degradation of paint, wood, and porous surfaces.
If left untreated, it leads to staining, weakening of structures, and health issues (respiratory irritation, allergies).
Solution:
Regular soft washing eliminates mildew and prevents regrowth.
Threat #2 – Mold
What is it?
Mold is a fungus that penetrates deep into porous surfaces like stucco, concrete, and wood.
It appears as black, green, or blue patches and spreads rapidly.
Mildew is essentially an early-stage mold that hasn’t deeply embedded itself yet
Both mold and mildew thrive in humid coastal environments, degrade surfaces, and require professional cleaning to prevent long-term damage.
Scientific Data & Damage:
The EPA states that mold exposure can cause severe indoor air quality issues.
Mold can cause rotting, material breakdown, and structural damage in just a few months.
Solution:
Hi/Low pressure washing with antimicrobial treatments stops mold from damaging surfaces.
Threat #3 – Algae
What is it?
Algae are microscopic plant organisms that form dark streaks and green patches on roofs, walls, and sidewalks.
Scientific Data & Damage:
The Gloeocapsa Magma algae strain, common in humid climates, causes roof staining, leading to reduced reflectivity and increased energy costs.
Algae make surfaces slippery and hazardous (walkways, patios, driveways).
Solution:
Soft washing and pressure washing prevent buildup and reduce energy consumption by keeping roofs clean and reflective.
Threat #4 – Corrosion
What is it?
Corrosion is the chemical breakdown of metal surfaces due to salt exposure, moisture, and pollutants.
Scientific Data & Damage:
The National Association of Corrosion Engineers (NACE) reports that coastal properties deteriorate up to 5x faster than inland properties due to airborne salt.
Corrosion causes rust on railings, gutters, metal roofs, and fasteners, leading to expensive replacements.
Solution:
Regular salt-neutralizing washes extend the life of metal components.
Threat #5 – Oxidation
What is it?
Oxidation is the gradual breakdown of painted and metal surfaces due to UV exposure and oxygen exposure.
It appears as chalky residue on siding, metal, and plastic.
Scientific Data & Damage:
Prolonged oxidation weakens coatings, leading to fading, chalking, and premature aging of materials.
The Paint Quality Institute states that oxidation can shorten paint life by 50% in high-exposure areas.
Solution:
Oxidation removal techniques restore surfaces and extend their lifespan.
Threat #6 – Hard Water Build Up and Staining
What is it?
Hard water contains high levels of calcium and magnesium that leave behind mineral deposits when water evaporates.
Common sources: Irrigation overspray, sprinkler systems, hose bib leaks, condensation and rainwater runoff.
If untreated, buildup can lead to permanent etching, especially on glass, metal, and polished surfaces.
Prevention & Solution:
Regular cleaning with professional-grade removers before buildup occurs.
Hydrophilic glass coatings to reduce water adhesion.
Adjusting irrigation systems to prevent overspray.
Threat #7 – Environmental Staining: Organic & Acid Rain
What is it?
Overhanging tree canopies and irrigation overspray's causes stubborn stains on underlying surfaces
Acid rain is caused by air pollution mixing with moisture, creating sulfuric and nitric acids that etch and stain surfaces over time.
Contributes to black streaking and discoloration on windows, roofs, siding, and stone surfaces.
Accelerates oxidation and corrosion of metals.
Prevention & Solution:
Frequent washing to neutralize acidic residues before they cause damage.
Use of pH-balanced cleaning solutions to counteract acidity.
Protective sealants and coatings to prevent etching on glass and masonry.
Threat #8 – Tree Canopy and Impeding Landscape
Trees add beauty and shade but create several maintenance challenges:
Clogged Gutters – Leaves, twigs, and debris accumulate, leading to water overflow, roof leaks, and foundation issues.
Increased Biological Growth – Shaded areas retain moisture, creating the perfect environment for mildew, mold, and algae to thrive.
Tree Sap & Pitch – Sticky resin from certain trees (pines, oaks, maples) bonds to surfaces, attracting dirt and making removal difficult.
Roof & Siding Damage – Falling branches, excessive moisture, and root intrusion near foundations can lead to costly repairs.
Prevention & Solution:
- Regular gutter cleaning to prevent blockages.
- Routine pressure washing and soft washing to remove buildup.
- Tree trimming to reduce shade coverage and debris accumulation.
- Specialized cleaning for tree sap removal before it causes staining or surface damage.
The Cost of Neglecting These Threats
Increased repair costs
Corrosion and Oxidation damages building materials leading to re-painting, repairs and replacement costing thousands of dollars.
Higher energy bills
Algae on roofs reduces reflectivity, increasing cooling costs.
Reduced property value
Mildew, Mold and Algae literally eats away surfaces and is unsightly in the process, decreasing curb appeal and resale value.
Safety risks
Mold and algae can create slippery surfaces and health hazards.
