Chicagoland Masonry & Concrete
Power Washing & Siloxane Sealing for Masonry & Concrete in Chicagoland
Cleaning and sealing masonry and concrete before winter is the single most cost-effective preventive maintenance investment you can make on your Chicagoland property.
Dirty, Unsealed Masonry Is Vulnerable Masonry
The older brick and masonry homes of Oak Park, River Forest, Hinsdale, and Elmhurst are architectural assets, but they require periodic cleaning and protection to hold their value and resist the aggressive Chicagoland climate. Biological growth (algae, mold, lichen) etches into porous masonry surfaces. Atmospheric soiling embeds into open pores. Unsealed masonry absorbs significantly more water per freeze-thaw cycle than properly sealed masonry, accelerating joint erosion and spalling. Power washing removes the embedded soiling and growth; professional-grade siloxane sealing closes the pores against further water penetration.
Biological Growth
Algae, mold, lichen, and moss grow into masonry pores, etching the surface and creating moisture-retaining layers that accelerate freeze-thaw damage.
Atmospheric Soiling
Urban particulates, road film, and carbon deposits embed in masonry pores and concrete surfaces, creating persistent staining that cannot be removed without pressure washing.
Efflorescence
White mineral deposits on brick and concrete surfaces are removed by cleaning and addressed long-term by reducing water infiltration through proper sealing.
Unsealed Masonry Vulnerability
Unsealed brick absorbs up to 10 times more water than properly sealed surfaces, dramatically increasing freeze-thaw damage over successive winters.
Concrete Surface Deterioration
Driveways, patios, and flatwork left unsealed absorb deicing salts and moisture that accelerate scaling and spalling from below the surface.
What We Do & How We Do It
Low-Pressure Masonry Washing
We wash masonry at controlled pressures appropriate to brick age and condition, never the high pressure used on concrete that damages historic brick faces and erodes mortar joints.
High-Pressure Concrete Cleaning
Driveways, patios, sidewalks, and concrete flatwork are cleaned at pressures appropriate to the surface type and condition.
Efflorescence Treatment
Efflorescence deposits are treated with dilute acid cleaning solutions prior to washing to neutralize the mineral deposits before pressure removal.
Siloxane Penetrating Sealer Application
We apply professional-grade penetrating siloxane water repellents (Prosoco, ChemMasters, and equivalent systems) that penetrate the masonry matrix and chemically line the pores, repelling liquid water while remaining vapor permeable. These are not film-forming coatings and do not change the appearance of the masonry.
Concrete Surface Sealing
Driveways and flatwork are sealed with penetrating concrete sealers appropriate to the surface use and condition, protecting against salt infiltration and freeze-thaw damage.
Preventive Maintenance vs. Reactive Repair
Cleaning and sealing a standard Chicagoland brick facade costs a fraction of the tuckpointing and spalling brick repair that unsealed masonry requires over a 10-year period. Professional siloxane sealing on sound, clean masonry is the highest-leverage preventive maintenance investment available to masonry homeowners. Homeowners in Hinsdale, Western Springs, La Grange, and Clarendon Hills who establish a 5–7 year cleaning and sealing cycle maintain better-condition masonry that requires less corrective repair over time.
