Remove Buildup Before It Causes Damage

Pressure washing services for homes and buildings in San Francisco

Your property in San Francisco collects dirt, mildew, and grime from coastal moisture and urban pollution that darken siding, stain walkways, and accelerate the breakdown of exterior coatings. Left untreated, buildup holds moisture against wood and stucco, shortening the life of paint and creating conditions for rot. mg simms painting and decorating provides pressure washing to remove surface contaminants and prepare exteriors for painting or routine maintenance.

The process uses controlled water pressure to clean siding, concrete, decks, and fences without damaging underlying materials. Techniques are adjusted based on surface type, with lower pressure applied to wood and stucco and higher settings used for concrete and masonry. Pressure washing is often paired with exterior painting to ensure coatings bond properly and last longer.

Request pressure washing as part of a full exterior refresh for your San Francisco property.

Safe Techniques That Protect Surfaces and Landscaping

mg simms painting and decorating assesses each property in San Francisco to determine the correct pressure level, nozzle type, and cleaning agent for the surface being treated. Equipment includes gas-powered washers for large areas and electric units for detail work around windows, trim, and plantings.

After pressure washing, you will see clean siding free of dark streaks and mold, bright walkways without embedded dirt, and wood surfaces that show their original color without staining. Water runs off cleanly instead of pooling in areas where buildup once trapped moisture, and exteriors look maintained rather than neglected.

The service includes setup, washing, and rinse-down of surrounding areas to prevent soap or debris from damaging plants or staining adjacent surfaces. It does not include repairs to cracked siding, broken boards, or damaged masonry, though visible issues are noted for follow-up. Pressure washing helps extend the life of exterior coatings and improves curb appeal without requiring a full repaint.

What Property Owners Ask Before Scheduling

Property owners often want to know how often pressure washing is needed, whether it damages paint or siding, and what kind of results to expect on different materials.

What surfaces can be safely pressure washed?
You can have siding, concrete, brick, stucco, wood decks, and fences cleaned using appropriate pressure settings. Delicate surfaces like painted wood or older stucco require lower pressure to avoid damage.
How often should a San Francisco property be pressure washed?
You should schedule pressure washing every one to two years depending on exposure to moisture, shade, and traffic. Properties near the coast or under tree cover may need more frequent cleaning to prevent mildew buildup.
When should pressure washing be done before painting?
You should pressure wash at least one to two days before painting begins to allow surfaces to dry completely. This removes contaminants that prevent primer and paint from bonding properly.
What kind of buildup does pressure washing remove?
You receive removal of dirt, mildew, mold, algae, pollen, and surface stains caused by moisture and pollution. Heavily embedded stains or rust may require additional treatment or scrubbing.
Why is pressure washing important for Bay Area homes?
Coastal moisture and fog create conditions that promote mildew and organic growth on exterior surfaces. Regular cleaning prevents these contaminants from holding water against siding and accelerating deterioration.
