Brick is one of the most durable materials on a home, but it is also porous. Dirt, mildew, algae, moss and efflorescence settle into the surface and the mortar, especially on shaded walls in East Tennessee. Here is how brick walls, foundations, chimneys and walkways are cleaned safely, and why too much pressure does more harm than good. For a professional clean, see our house washing service for brick homes and our concrete and hardscape cleaning service for walkways and patios.

Why Brick Needs a Careful Approach
Brick faces can chip and mortar joints can erode under high pressure, and water forced into cracks can lead to moisture problems behind the wall. Harsh acid-based cleaners can discolor brick. The safest approach relies on the right cleaning solution and controlled, low pressure rather than force.
How Brick Is Cleaned Safely
- Inspect first. Look for loose bricks, cracked or crumbling mortar and damaged areas. These should be repaired before cleaning.
- Protect the area. Cover plants, close windows and doors, and protect outlets and fixtures.
- Pre-wet the brick. Saturating brick first keeps cleaning solution from soaking in too deeply.
- Apply a brick-safe solution. Let it dwell to loosen dirt and organic growth, and use a soft brush on stubborn spots.
- Rinse with low pressure. Use a wide spray pattern from a safe distance, working top to bottom.
- Let it dry. Allow the brick to dry fully before any sealing.
Brick Homes
A brick exterior benefits from the same gentle approach as siding. A professional wash removes dirt and growth from walls and trim together, and our guide to cleaning different types of siding covers brick alongside vinyl and wood.
Indoor Brick and Fireplaces
Pressure washing is not appropriate indoors. Interior brick and fireplaces should be cleaned by hand with a brush and a gentle cleaner, protecting nearby floors and furnishings.
Keeping Brick Clean Longer
Trim plants and branches that keep brick shaded and damp, keep gutters flowing so water does not run down walls, and address mortar repairs promptly. Sealing can add protection. The M.O.O.R.E.S. Maintenance Club keeps your outdoor surfaces on a regular cleaning schedule. For patios, read our guide to cleaning a brick patio.
