Your Property's Exterior
Is Your First Impression.
Grime-covered siding, stained walkways, and filthy loading docks don't go unnoticed — by customers, tenants, or building inspectors. Cronin Sealcoating delivers professional commercial power washing that cleans thoroughly, protects surfaces, and keeps your property looking like the business you run.
Who We Work With
Built for the People
Who Manage Properties
Commercial power washing isn't a one-size situation. A retail plaza has different needs than a food service facility, and an industrial property requires a different approach than a medical office building. We work across property types and understand what each one demands.
Office & Commercial Buildings
Tenants and clients form impressions before they walk through the door. Clean building exteriors, bright entrances, and well-maintained walkways signal that the property is professionally managed.
Retail & Restaurant Properties
Customer-facing properties take a beating — foot traffic, spills, grease, and exhaust accumulate fast. We work early mornings and off-hours to keep your operation running without disruption.
Industrial & Warehouse Facilities
Loading docks, truck aprons, dumpster pads, and facility exteriors accumulate grease, oil, and biological growth that creates both safety hazards and compliance concerns. We handle the full scope.
HOAs & Multi-Family Properties
Common area walkways, building exteriors, pool decks, and parking structures serving residents. We coordinate with property managers and boards to plan work around resident schedules.
Schools, Institutions & Municipalities
Civic buildings, public facilities, and institutional properties with specific scheduling windows and compliance requirements. We understand how public-sector and nonprofit work operates.
Property Management Companies
If you manage multiple properties, a single reliable contractor who shows up, communicates clearly, and does work that holds up is worth more than a long vendor list. That's what we aim to be.
More Than Cosmetic
Why Commercial Properties
Need Professional Cleaning
Commercial exteriors accumulate contamination faster than residential ones — heavier traffic, more vehicles, food service operations, loading activity, and greater building mass all contribute. The results compound: what starts as cosmetic eventually becomes a liability, a code concern, or a surface that has to be replaced ahead of schedule.
Tenant & Customer Perception
A clean property signals competent management. Tenants renew leases in well-maintained buildings. Customers form opinions in the parking lot before they walk through the door. The exterior sets the tone for everything inside.
Liability & Safety
Algae and biological growth on walkways, steps, and loading areas create slip-and-fall hazards that property owners are responsible for. Regular power washing removes the growth and the liability risk it creates.
Surface & Asset Protection
Biological growth holds moisture against building exteriors and pavement. Grease penetrates concrete and asphalt. Salt residue accelerates corrosion and surface breakdown. Cleaning protects the materials underneath.
Compliance & Inspections
Food service facilities, healthcare properties, and municipal buildings face exterior cleanliness requirements. Grease trap areas, dumpster pads, and service entrances are common inspection points that cleaning keeps in order.
Pre-Painting & Maintenance Prep
Any exterior painting, caulking, or masonry work requires a clean substrate. Professional power washing before maintenance projects ensures the work bonds properly and lasts as long as the product is rated to perform.
Property Value & Marketability
A well-maintained exterior commands better lease rates, supports higher appraisal values, and makes properties easier to show and sell. Deferred exterior maintenance communicates the wrong things to prospective tenants and buyers.
What We Clean
Commercial Power Washing
Services We Provide
Every surface type and every contamination condition calls for a specific approach. We match pressure, technique, and cleaning agents to the surface at hand — high-pressure where concrete and masonry can handle it, soft-wash methods where cladding and painted surfaces require something gentler. No single setting applied to everything.
Building Exterior & Siding
Commercial building facades accumulate atmospheric grime, exhaust deposits, algae, mildew, and biological staining at a rate that residential properties don't match. We clean all commercial cladding types — from brick and precast concrete to EIFS, metal panel, and painted CMU — using the technique appropriate to each.
- Brick, concrete block, precast, and masonry cleaning
- Metal panel, EIFS, and composite cladding — soft-wash method
- Painted and stucco surfaces — pressure matched to substrate
- Algae, mildew, exhaust staining, and atmospheric deposit removal
- Soffit, fascia, canopy undersides, and trim cleaning
- Preparation for exterior painting and caulking projects
Parking Lots & Asphalt Surfaces
Commercial parking lots collect oil drips, fuel residue, tire rubber, road salt, and biological growth across large surface areas. When we're preparing a lot for sealcoating and observe contamination we believe will affect adhesion, we'll recommend power washing first and explain why — but only when we genuinely see the need.
- Oil and fuel residue removal from high-traffic areas
- Road salt and de-icer deposit cleaning
- Biological growth removal from lot edges and drainage areas
- Concrete parking decks and structured parking surfaces
- Recommended before sealcoating when surface contamination warrants it
Walkways, Entries & Common Areas
Building entrances, tenant walkways, and common area hardscape are the highest-visibility surfaces on any commercial property — and the ones most likely to create slip hazards when biological growth establishes. We clean them thoroughly and safely, regardless of surface material.
- Concrete, brick, pavers, bluestone, and natural stone
- Algae and biofilm removal — eliminates slip hazard
- Building entry plazas and covered walkway surfaces
- Stairwells and exterior steps
- ADA access ramps and accessible pathways
- Prep for paver sealing or joint sand replacement
Loading Docks & Service Areas
Loading docks and service entrances accumulate grease, oil, organic waste, and heavy road contamination faster than any other area of a commercial property. Beyond the appearance issue, this creates real slip-and-fall liability and can trigger code concerns at food service and healthcare facilities. We clean these areas with the appropriate agents for the contamination type.
- Grease, oil, and hydraulic fluid removal from dock surfaces
- Dock leveler areas and pit cleaning
- Truck aprons and service drive approach surfaces
- Food service facility exterior service areas
- High-pressure cleaning with grease-cutting agents where needed
Dumpster Pads & Trash Enclosures
Dumpster pad areas are among the most contaminated surfaces on any commercial property — organic waste, grease, and liquid runoff accumulate in a concentrated zone. They're also among the most frequent exterior inspection points for food service, healthcare, and municipal tenants. We clean them to a standard that holds up to scrutiny.
- Heavy organic contamination and grease removal
- Concrete pad surfaces, curbing, and enclosure walls
- Odor reduction through thorough cleaning
- Drainage channel and catch basin perimeter cleaning
- Regular maintenance scheduling available for high-use facilities
Retaining Walls, Curbing & Site Hardscape
Retaining walls, concrete curbing, decorative masonry, and exterior site features accumulate staining, efflorescence, and biological growth that degrades both appearance and surface integrity over time. We restore them as part of a full-property clean or as standalone targeted work.
- Concrete and masonry retaining wall restoration
- Efflorescence treatment and removal
- Granite and stone curbing cleaning
- Decorative hardscape and site feature restoration
- Pool decks, amenity areas, and outdoor common spaces
Conditions We Address
What We See at
Commercial Properties
These are the contamination conditions we encounter most often at Massachusetts commercial properties. Each one has a specific cleaning approach — and some are more than just an appearance problem.
Atmospheric Staining & Exhaust Deposits
Commercial buildings near roadways accumulate exhaust particulate and atmospheric deposits that bond to masonry and cladding surfaces over time. This is distinct from biological growth and requires specific cleaning agents to address effectively.
Grease & Oil Accumulation
Loading docks, service drives, and food service exterior areas develop grease and oil buildup that standard pressure alone doesn't fully remove. We use appropriate degreasers for the contamination type — not just high pressure and water.
Algae & Biological Growth
Shaded walkways, north-facing surfaces, and areas near landscaping develop algae and biofilm that creates both a slip hazard and a staining problem. This is one of the more common reasons property managers call us — and one of the most straightforward problems to resolve.
Efflorescence on Concrete & Brick
White salt deposits migrating to the surface of concrete block, brick, and masonry — efflorescence — is a common condition on commercial buildings. It's not structural, but it looks like deterioration and responds well to professional cleaning and treatment.
Oil Spotting & Tire Rubber
High-traffic commercial parking lots develop concentrated oil spotting in parking stalls and tire rubber deposits at stops and turning points. This contamination is visible, looks poorly maintained, and in high-concentration areas can affect pavement performance.
Organic Waste & Dumpster Runoff
Dumpster pad areas at food service, healthcare, and multi-tenant retail facilities develop severe organic contamination from waste runoff. This creates odor, attracts pests, and is a consistent code and inspection concern. Regular cleaning is the only effective management strategy.
How We Work
Technique and Pressure
Matched to the Surface
Commercial properties present a wider range of surface types and contamination conditions than residential jobs — and applying the wrong approach to a commercial surface causes real problems. High-pressure washing on EIFS or synthetic stucco can fracture the surface coating and drive water into the wall assembly. The wrong cleaning agents on brick can accelerate spalling and staining. Pressure that's too aggressive on painted CMU can strip coatings that cost thousands of dollars to restore.
We evaluate each surface before anything gets turned on. Masonry and concrete get high-pressure treatment suited to the material and its condition. Metal panel, EIFS, and painted cladding surfaces get soft-wash technique — lower pressure with appropriate dwell time and cleaning solution for the contamination type. Grease-contaminated areas at loading docks and service spaces get degreasing agents selected for the specific contamination, not just pressure.
Commercial jobs also require attention to operational continuity. We schedule around your business hours, work in sections where needed to maintain access, and communicate clearly with facility contacts and property managers throughout the job. The goal is a clean property with minimum disruption — and we plan from the beginning to deliver both.
What to Expect on Every Job
Our commercial power washing process, in plain terms:
- Property walk and surface assessment before any work begins — every surface type identified, every contamination condition noted
- Pressure and cleaning agents selected for the specific surface and condition — not a single setting applied to the whole property
- Soft-wash on all cladding, EIFS, painted, and sensitive surfaces — no moisture intrusion, no surface damage
- Scheduling around your business hours — early morning, after-hours, and phased work available
- Facility contacts and property managers kept informed throughout the job
- Property left clean on completion — no detergent residue, no displaced debris
- Honest assessment of what we find — if a surface needs something beyond washing, we'll tell you directly
What to Expect
Our Commercial Power Washing
Process
Commercial power washing jobs require more coordination than residential work — multiple surfaces, active operations, tenant or customer access to maintain. Our process is built around delivering clean results without disrupting yours.
On-Site Assessment & Written Estimate
We visit the property, walk every surface in scope, and document conditions — contamination type, surface materials, drainage considerations, and any areas that need special attention or a different technique. You receive a written, itemized estimate before anything is scheduled.
No obligationScheduling & Operational Coordination
We work with the facility manager or property contact to plan the job around your business operations. Early morning starts, after-hours scheduling, and phased access plans are all available depending on what your property requires. We communicate the schedule clearly and stick to it.
Minimal disruptionSetup & Site Preparation
On the day of the job, we set up equipment, address any protective measures needed for landscaping or adjacent surfaces, and do a final walkthrough to confirm scope before starting. Drains and site features that need protection are handled before the first nozzle is turned on.
Careful preparationSurface-by-Surface Cleaning
We work through each area systematically — adjusting pressure, technique, and cleaning agents as we move from surface to surface. Building cladding gets soft-wash treatment. Concrete and masonry get high-pressure surface cleaning. Grease-contaminated areas get appropriate degreasers. We don't rush; thorough commercial cleaning requires working each surface properly, not passing over it quickly.
Technique matched to surfaceFinal Rinse & Property Review
All surfaces are rinsed clean of cleaning agents and residue. We do a full property walkthrough with the facility contact to review results and note anything we observed during the job — surface conditions, drainage concerns, or areas that may benefit from follow-up attention.
Transparent communicationCleanup & Documentation
Equipment is packed out, the property is left clean, and any areas temporarily blocked during the job are restored to normal access. If the scope included parking lot or driveway washing as part of a sealcoating project, we coordinate the follow-up timeline so surfaces are fully dry before the next phase begins.
Clean property, every timeThe Full Picture
Power Washing &
Commercial Sealcoating
If a commercial parking lot is scheduled for sealcoating, power washing may be part of the conversation — but only when we actually see a reason for it. When we assess a lot and find oil-heavy areas, significant biological buildup, or contamination we believe will interfere with sealcoat adhesion, we'll recommend washing first and explain our reasoning. If the surface looks clean and ready to seal, we say so and move forward.
Sealcoat applied over a heavily contaminated surface won't bond the way it should — and that's a waste of the investment. Our goal is to give each lot the preparation it genuinely needs, not to add services that don't make a difference.
Commercial power washing is also available as a fully standalone service — for building exteriors, walkways, loading areas, dumpster pads, and any other surfaces that need attention independent of any sealcoating work.

Planning Ahead
Scheduled Around
Your Operation
Commercial power washing has to work around your tenants, your customers, and your business hours — not the other way around. We build scheduling flexibility into every commercial job from the start.
-
Early Morning & After-Hours Scheduling Retail, restaurant, and high-traffic properties can be scheduled for early morning starts or evening work — whatever keeps your operation running with the least disruption.
-
Phased Work for Large Properties Large facilities and multi-building properties can be completed in phases — cleaning one section at a time while the rest of the property remains accessible.
-
Written Scope & Timeline Every commercial job comes with a written estimate, scope of work, and projected schedule before we start. No surprises during the project.
-
Recurring Maintenance Scheduling High-use facilities — particularly food service, healthcare, and industrial properties — benefit from scheduled recurring cleaning. We can set up a maintenance schedule that keeps conditions under control year-round.
Spring & Summer Schedules Fill Early
The bulk of commercial exterior cleaning happens in spring and early summer. Property managers and facilities directors who reach out in late winter get first access to preferred scheduling windows. A free estimate costs nothing and gets you in the queue.
