Power Washing & Exterior Cleaning in Greater Boston
First impressions start at the front door — make sure your building's exterior lives up to what's inside.
A clean exterior signals a well-managed property
Before a prospective tenant steps through the front door, before a resident returns home, before a client walks into your office — they see the outside of your building. Dirty siding, stained walkways, algae-covered entryways, and neglected exteriors signal to everyone who approaches that a property isn't being actively maintained. A clean, well-maintained exterior signals exactly the opposite.
Beyond aesthetics, exterior surfaces accumulate algae, mildew, pollen, road salt, and urban pollutants that cause real structural damage if left untreated. Boston's coastal air and winter road salt create one of the harshest exterior environments for commercial buildings in the Northeast — annual power washing isn't a cosmetic choice, it's maintenance.
78-Clean's power washing crews service Greater Boston properties year-round — removing the buildup that accumulates between seasons and keeping building exteriors in the condition that property managers, residents, and owners expect.
Power Washing Services
Building exterior washing
Our building exterior washing service removes dirt, exhaust residue, algae, and mildew from siding, brick, stone, and concrete — restoring your building's original appearance and protecting the surface underneath from the cumulative damage that biological growth and urban pollutants cause over time. Building awnings are also within scope — fabric and metal awnings accumulate grime, mildew, and staining that power washing restores without damaging the material.
Walkway and entrance cleaning
Walkways and building entries accumulate staining, biological growth, and surface buildup that routine cleaning can't address. Our power washing service removes this buildup from concrete, brick, and stone surfaces — creating a clean, welcoming first impression and reducing the slip risk that algae-covered surfaces create.
Slip-and-fall claims from dirty or algae-covered walkways are among the most common premises liability cases in Massachusetts — regular cleaning reduces both the risk and your exposure.
Parking garage and lot cleaning
Oil stains, tire marks, debris, and biological growth accumulate on parking surfaces and create both appearance and safety concerns. 78-Clean power washes parking lots and garage levels where conditions allow — and where garage ventilation doesn't permit power washing, our crews sweep and clean the surface thoroughly. Knowing the difference between a garage that can be safely power washed and one that requires an alternative approach is the kind of operational experience that matters in a dense urban market like Greater Boston.
Waste bin and dumpster washing
Trash and recycling bins accumulate bacteria, odors, and organic residue that attract pests and create health concerns for building residents. Our bin washing service pressure-cleans and sanitizes bins and dumpsters on a scheduled basis — keeping your property hygienic and odor-free.
For multi-unit residential buildings, quarterly bin washing is the minimum recommended frequency to prevent fly and rodent activity — monthly service is common during warmer months.
Graffiti Removal
78-Clean provides professional graffiti removal from a variety of surfaces — responding quickly to restore your building's appearance before the situation escalates.
Prompt graffiti removal is the single most effective deterrent against repeat vandalism on a property.
Post-winter exterior clean
Boston's winter leaves a residue that most property managers underestimate. Road salt, sand, and biological growth accumulate on building exteriors, walkways, and parking surfaces throughout the cold months — and the damage is cumulative.
Road salt begins degrading concrete and masonry within weeks of exposure — and the damage is cumulative. A single post-winter wash can prevent years of surface deterioration.
78-Clean's post-winter exterior clean removes corrosive salt deposits and winter buildup before they cause long-term structural damage — timed for early spring when temperatures consistently support effective washing.
Seasonal Scheduling
78-Clean recommends power washing at minimum twice per year for Greater Boston properties — once in spring following winter, and once in fall before temperatures drop. For high-traffic or high-visibility properties, quarterly service delivers the most consistent results.
78-Clean offers scheduled power washing programs as part of ongoing facility services agreements — exterior maintenance coordinated alongside your cleaning, trash, and landscaping programs so nothing gets deferred or forgotten between seasons. Your Relationship Manager tracks your schedule and ensures service happens when it should, without you having to initiate it.
78-Clean crews are trained to identify exterior maintenance issues beyond the areas being cleaned — surface deterioration, drainage concerns, and visible damage get flagged back to your Relationship Manager before they become expensive repairs.
Standalone service or part of a broader program
Power washing is available as a one-time service or as part of a scheduled maintenance program. Properties that combine power washing with 78-Clean's cleaning, landscaping, and facility services programs benefit from a single Relationship Manager coordinating all exterior and interior service delivery — one schedule, one invoice, one point of accountability year-round.
