Clean masonry isn't just about curb appeal. Removing organic growth and surface contaminants protects the brick and is the essential first step before any sealing or restoration.

What Masonry Power Washing Is

Masonry power washing — done correctly — is the controlled cleaning of brick, block, and stone to remove built-up dirt, atmospheric grime, efflorescence, and biological growth like algae, moss, and mildew. The goal is a clean, restored surface, not a stripped one.

The phrase "power washing" is misleading on masonry. The right method usually isn't high pressure at all. It's a soft-wash process: appropriate cleaning solutions do the work of breaking down growth and grime, and controlled low pressure rinses it away. The cleaner does the lifting, not brute force.

Why High Pressure and Sandblasting Damage Brick

This is the most important thing to know before anyone points a wand at your masonry.

Brick has a hard, fired outer skin that protects the softer, more porous body underneath. High-pressure washing and sandblasting erode that fired surface. Once it's gone, the exposed inner brick soaks up water far more readily — which means more staining, more efflorescence, faster deterioration, and accelerated freeze-thaw damage in Naperville winters.

High pressure also blows out mortar joints, carving out the very material that keeps water out of the wall. Sandblasting is worse: it permanently roughens and pits both brick and stone. We see masonry across the suburbs that was "cleaned" this way and ended up needing tuckpointing or brick repair because of it. The damage is irreversible.

Gentle soft-washing avoids all of this. It cleans the surface thoroughly while leaving the protective fired skin and the mortar joints intact.

What We Remove

• Dirt and atmospheric grime — years of dust, traffic film, and pollution buildup
• Efflorescence — the white, chalky mineral staining that moisture leaves behind
• Organic growth — algae, moss, mildew, and the green or black biological staining common on shaded north-facing walls
• Surface stains — runoff streaking, rust bleed, and general discoloration

When we find efflorescence, we'll also tell you whether it points to an underlying moisture issue, since cleaning the surface alone won't stop salts that keep being pushed out by water moving through the wall.

Cleaning as Prep Before Sealing

If you're planning to seal your masonry, cleaning isn't optional — it comes first. Applying masonry sealing over dirty brick traps grime, organic growth, and contaminants under the sealer, which looks bad and undermines the protection you're paying for.

A proper soft-wash gives the sealer a clean, sound surface to bond to so it can do its job: shedding water and resisting future staining. Cleaning and sealing together is one of the most cost-effective ways to extend the life of brick and stone in our climate.

Our Process

1. Assessment — We inspect the masonry, identify what's staining it, and check the condition of the brick and mortar before choosing a cleaning approach.
2. Protection — We protect plantings, fixtures, and adjacent surfaces around the work area.
3. Soft-wash cleaning — We apply the appropriate cleaning solution for the type of soiling, let it work, and rinse with controlled low pressure that won't harm the surface.
4. Inspection and touch-up — We check the results and address any stubborn areas.
5. Walkthrough — We walk you through the finished work and flag any masonry repairs the cleaning may have revealed.

What Affects the Price

We quote after seeing the property, because every building is different. The main factors are the total square footage of masonry, the number of stories and the access required (taller facades may need extra equipment), the type and severity of the staining, whether organic growth requires extra treatment, and whether you're combining cleaning with sealing or repairs. We provide a free on-site estimate so you get a real number for your specific property. Emerald Masonry LLC has a $5,000 project minimum.

Local Context: Naperville Masonry

Naperville's housing stock is a mix — from historic brick homes near the downtown and the Naper Settlement area to the large brick-and-stone subdivisions built through the later decades of growth in DuPage County. Brick facades, stone accents, and full masonry chimneys are common across the city.

DuPage County's mature tree canopy and humid summers mean a lot of Naperville masonry collects algae and organic growth, especially on shaded and north-facing walls. Combine that with the freeze-thaw cycles of local winters, and keeping masonry clean and properly sealed becomes real maintenance, not just cosmetics. Cleaning the wrong way — with high pressure — only speeds up the damage those winters cause.

Frequently Asked Questions

Will power washing damage my Naperville brick?

High-pressure washing and sandblasting can absolutely damage brick by stripping the fired surface and eroding mortar joints, which leaves the masonry more porous and prone to water damage. We use a gentle soft-wash approach with appropriate cleaners and controlled pressure that cleans the surface without harming it.

Can you remove the white chalky staining (efflorescence) on my brick?

Yes. That white residue is efflorescence — mineral salts carried to the surface by moisture. We can clean it off, but because it signals moisture moving through the masonry, we'll also point out whether an underlying issue like failing mortar or drainage should be addressed so it doesn't keep returning.

Should I clean my masonry before sealing it?

Yes. Sealing dirty masonry traps dirt, organic growth, and contaminants under the sealer and gives a poor result. A proper gentle cleaning is the first step before any masonry sealing so the surface is clean and the sealer can bond and perform as intended.

Do you clean both homes and commercial buildings in Naperville?

Yes. We soft-wash residential brick and stone as well as commercial masonry facades throughout Naperville and DuPage County. Call (708) 288-1696 to schedule a free on-site estimate.
