Power washing is a high-pressure cleaning process that removes dirt, mildew, chalking, and biological growth from masonry, siding, wood, and concrete surfaces — when matched to the right pressure and technique for each substrate. At Fortune Restoration, we’ve been power washing Chicago homes, commercial buildings, and historic landmarks since 1979. Done correctly, it transforms a property’s curb appeal and prepares surfaces for paint or masonry work. Done incorrectly, it can blast mortar out of brick joints, gouge softwood, and force water behind siding. The difference is experience.
If you’re planning an exterior project — a paint job, a tuckpointing repair, a stucco refresh, or just a deep clean before spring — start with the right wash. Request a free estimate or call us at 847-647-2500.
What Power Washing Actually Does (and Doesn’t Do)
Pressure washing forces water through a narrow nozzle at pressures ranging from 1,500 to 4,000+ PSI. That force lifts surface contamination — dirt, mildew, chalking paint, atmospheric soot, salt residue, biological growth — off porous and non-porous surfaces alike. On the right substrate at the right pressure, it’s the most efficient surface preparation method available.
What it doesn’t do is fix structural problems. Spalling brick, deteriorated mortar, rotted wood, and failing stucco need masonry repair or carpentry work — not more pressure. Aiming a 3,500 PSI tip at a soft historic brick wall to “clean it up” will accelerate the damage you were trying to manage. The first job of a Chicago power washing contractor is knowing what each surface can take.
Power Washing vs. Soft Washing: The Distinction That Matters
Soft washing uses lower pressure (under 500 PSI) combined with cleaning solutions — surfactants, mildewcides, algaecides — to clean delicate surfaces without mechanical damage. It’s the right approach for historic brick, soft limestone, older stucco systems, painted wood with existing finish, and roofing materials. High pressure on those surfaces causes more harm than the cleaning is worth.
Most Chicago residential and commercial buildings need a mix of both methods on a single property. Concrete driveways and walkways tolerate aggressive pressure cleaning. Vinyl and aluminum siding respond well to moderate pressure. The brick facade above grade and the painted wood trim around windows almost always need a softer hand. We assess each elevation before we touch a trigger.
Surfaces We Power Wash in Chicago
Our crews are trained on the pressure ranges, tip selections, and chemistry appropriate for each substrate found across Chicagoland’s housing stock and commercial inventory:
- Brick and masonry — modern brick tolerates more pressure than historic brick or lime mortar. We adjust accordingly. For severely soiled or stained masonry, our masonry services include chemical cleaning systems beyond what pressure alone can address.
- Stucco — older three-coat lime stucco is fragile. Aggressive pressure delaminates it. We use soft washing on virtually all stucco surfaces and follow up with targeted stucco repair as needed.
- Vinyl and aluminum siding — moderate pressure with the right cleaners removes algae, mildew, and grime without driving water behind the siding system.
- Wood siding, decks, and porches — softwood like pine and cedar gouges easily under high pressure. We use the lowest effective pressure and the right tip distance. For damaged wood, our porch and deck restoration and siding replacement services pick up where cleaning leaves off.
- Concrete driveways, sidewalks, and patios — the ideal surface for high-pressure cleaning. Embedded oil, rust, organic stains, and tire marks come right up.
- Patio pavers and natural stone — clean effectively at moderate pressure. Re-sanding the joints after cleaning is part of doing it right.
- Roofing materials — asphalt shingles should never see high pressure. Soft washing only.
- Fences, garden walls, and outbuildings — depending on the material, we calibrate accordingly.
Power Washing as Paint Preparation
One of the most common reasons Chicago property owners call us for power washing is as the first step of an exterior painting project. You cannot get good paint adhesion on a dirty surface. Atmospheric grime, mildew, chalking, and pollen that look invisible to the eye are the reason a paint job peels in two years instead of holding for ten.
A thorough wash before paint prep removes the contamination, opens the substrate for primer adhesion, and exposes any underlying problems — peeling areas, failing caulking, rotted wood — that need to be addressed before the first coat goes on. Our complete paint preparation process treats washing as the foundation of the work, not an afterthought. The National Park Service’s preservation guidance on painting wood emphasizes that surface preparation accounts for the vast majority of any paint job’s longevity, and the principle holds for modern construction too.
If the project involves disturbing paint on a home built before 1978, lead-safe work practices are required. Fortune Restoration is RRP-certified per the EPA’s Renovation, Repair and Painting Rule, and we contain wash water and debris appropriately on lead-presumptive jobs.
Why Power Washing Matters in Chicago’s Climate
Chicago’s combination of humid summers, freeze-thaw winters, and dense urban air loads more contamination onto building exteriors than most US cities deal with. The result is accelerated mildew growth on shaded north-facing elevations, sooty atmospheric deposits in dense neighborhoods, salt residue from de-icing chemicals tracked onto driveways and lower walls, and biological growth on porous surfaces year-round.
Regular cleaning slows down the underlying damage. Mildew and algae aren’t just cosmetic — they retain moisture against the substrate, which feeds rot in wood and accelerates freeze-thaw damage in masonry. Salt residue on lower brick walls draws moisture into the brick, where it freezes and expands. Efflorescence — those white salt deposits on brick — is a downstream symptom that often gets cleaned off without the underlying water source being addressed. Cleaning is part of maintenance; it isn’t a substitute for repair.
Most Chicago residential properties benefit from a thorough wash every two to three years. High-traffic commercial properties, north-facing exposures with chronic biological growth, and buildings near heavy traffic corridors often need annual cleaning to stay ahead of the staining cycle.
Power Washing for Property Managers and Commercial Buildings
For property managers responsible for Chicago’s flat-roofed courtyard buildings, multi-unit greystones, and commercial structures, power washing is part of a proactive building envelope maintenance program. Visible facade soiling drives tenant complaints and reduces marketability. Worse, the contamination that accumulates on parapet walls and coping holds moisture against the masonry — accelerating the deterioration that leads to City of Chicago violations.
Our property management clients use power washing in coordination with masonry waterproofing and sealing work, since the sequence matters: clean first, repair what the cleaning reveals, seal last. Reversing that order traps contamination behind the sealer and guarantees rework.
Contact our property management team to discuss multi-building cleaning programs, scheduled maintenance, and emergency response for graffiti or post-incident cleanup.
Power Washing for Historic Buildings and Landmarks
Historic masonry — the brick, terra cotta, limestone, and sandstone that define Chicago’s pre-war architectural character — does not tolerate the pressures used on modern construction. The National Park Service preservation brief on cleaning historic masonry is the definitive reference for this work, and it makes the case clearly: the gentlest method that produces acceptable results is always the right one. We’ve applied that principle on properties including the Grosse Point Lighthouse, the birthplace of Walt Disney, and Frank Lloyd Wright homes throughout Oak Park.
For these projects, we typically use very low pressure combined with carefully selected cleaning chemistry — sometimes nothing more than water and a soft brush — and we always run a test panel on an inconspicuous area before treating any larger surface. See our full historical landmark restoration portfolio for examples of this work.

Frequently Asked Questions About Power Washing in Chicago
How much does power washing cost in Chicago?
Residential power washing in Chicago typically runs from $300 to $800 for a single-family home, depending on the size of the property, the surfaces involved, and the level of soiling. Commercial buildings, multi-unit properties, and projects requiring boom lifts or scaffolding price separately based on access requirements. We provide free estimates with on-site assessment.
Can power washing damage my brick or siding?
Yes — incorrect pressure or technique can damage virtually any building surface. Historic brick and lime mortar are especially vulnerable to high pressure, which can blast mortar out of joints and erode soft brick faces. Wood siding can be gouged, and water can be forced behind vinyl or aluminum siding into the wall assembly. Professional power washing is about matching pressure and technique to the substrate — not about maximum force.
How often should I power wash my Chicago home?
Most Chicago residential properties benefit from a thorough wash every two to three years. North-facing elevations with chronic mildew growth, properties near busy streets or industrial areas, and buildings with significant biological staining may warrant annual cleaning. Commercial properties typically schedule cleaning annually or biannually as part of facade maintenance.
What’s the difference between power washing and pressure washing?
The terms are used interchangeably in everyday language, and most contractors don’t distinguish between them. Strictly speaking, power washing uses heated water while pressure washing uses unheated water — heat improves cleaning of greasy or oily contamination. In practice, the equipment, techniques, and applications overlap so heavily that the distinction rarely matters for residential or commercial buildings.
Is power washing necessary before painting?
Yes. Surface contamination — dirt, chalking paint, mildew, atmospheric pollutants — prevents primer and paint from adhering properly to the substrate. Skipping the wash is the single most common reason exterior paint jobs fail prematurely. A thorough cleaning is the first step of any quality paint preparation sequence, followed by scraping, feathering, caulking, and priming.
Can I rent a pressure washer and do this myself?
For concrete driveways and sidewalks, yes — DIY pressure washing is feasible and often economical. For building surfaces, especially historic masonry, stucco, or painted wood, we strongly recommend professional application. The risk of permanent damage from incorrect pressure settings, wrong tip selection, or improper technique is real, and repair costs typically exceed what you’d have paid for the wash.
Will power washing remove efflorescence from my brick?
Power washing removes the surface deposits, but efflorescence is a symptom of water moving through the wall and depositing soluble salts on the surface as it evaporates. Cleaning without addressing the water source means the deposits will return. The right sequence is to identify and repair the water entry points — failed mortar joints, cracked coping, deteriorated flashing — then clean, then seal. See our guide to efflorescence on Chicago brick for the full picture.
Do you offer power washing for commercial properties and HOAs?
Yes. We work extensively with property managers, HOA boards, and commercial building owners across Chicagoland on scheduled cleaning programs and one-time projects. Multi-building rates and recurring service contracts are available. Contact us to discuss your portfolio.
