Restoring Masonry: How Much To Power Wash A House with Brick?
Brick and stone homes are prized for their durability and timeless look. However, even masonry gets dirty. Moss, algae, and atmospheric pollution can turn vibrant red brick into a dull, blackened mess. Homeowners often ask how much to power wash a house with masonry, fearing that the cost might be prohibitive or, conversely, that they can just blast it themselves with a rental machine. Cleaning masonry requires a delicate touch. Brick is porous, and mortar is softer than stone; using high pressure can destroy the surface.
This article focuses on the specialized needs of masonry cleaning. We discuss why brick gets dirty, the dangers of high pressure on mortar joints, and the soft-wash techniques that restore the stone without causing structural damage.
The Porous Nature of Brick
Unlike vinyl siding, brick is like a hard sponge. It absorbs moisture and holds onto dirt and biological growth deep within its pores. “Black algae” (Gloeocapsa Magma) creates dark streaks that make the masonry look aged and neglected. Green moss can grow in the mortar joints, sending tiny roots into the cement. If you try to blast this growth out with high pressure, you force water deep into the brick. In winter, this trapped water freezes and expands, causing the face of the brick to pop off (spalling). Professional cleaning uses detergents that soak into the pores to kill the algae gently, allowing it to be rinsed away without saturating the core of the brick.
Protecting the Mortar Joints
The mortar between your bricks is the glue holding your house together. It is much softer than the brick itself. A concentrated high-pressure stream can cut into mortar like a knife, blasting it out and leaving gaps. This leads to the need for “re-pointing”—an expensive masonry repair process. A professional soft wash uses low pressure (similar to a heavy rain) that cleans the surface without eroding the mortar. Preserving the integrity of these joints is the most critical part of masonry cleaning. It ensures the wall remains structural and watertight.
Removing Efflorescence and Carbon Stains
Masonry is prone to specific types of staining. Efflorescence is a white, powdery salt deposit that appears when water moves through the brick. Carbon staining comes from car exhaust and pollution. These stains do not wash off with simple water pressure; they require specific chemical treatments to dissolve. A professional understands masonry chemistry. We use the right acidic or alkaline cleaners to neutralize these stains safely. Attempting to scrub these with the wrong chemical can set the stain permanently or bleach the brick color. Professional knowledge is key to a restoration-quality clean.
The Value of Restoration Cleaning
Cleaning masonry is one of the most dramatic home transformations possible. A freshly washed brick walkway or chimney looks brand new, instantly boosting curb appeal. It reveals the true colors of the stone that may have been hidden for decades. For homeowners considering selling, this restoration cleaning offers a massive ROI. It creates the impression of a solid, well-cared-for structure. The cost of a professional wash is a tiny fraction of the value added to the home’s appearance.
Conclusion Brick and stone require respect. Brute force cleaning damages them, but chemical soft washing restores them. By investing in professional masonry cleaning, you preserve the character and structural health of your home’s most durable feature.
