Commercial Power Washing & Sealing in Toronto

Seal Tech Inc has been supplying commercial power washing Toronto property owners and managers rely on for more than 15 years. From a low-rise office building in Scarborough to a condo walkway in North York, we use the right equipment and cleaning process for each surface so concrete, brick and stone come back looking clean, safe and well cared for.

Every commercial job starts the same way: we look at the surface, explain what we will do and provide a free written quote before any work begins. Ryan Leonard, the owner and president, is on site for jobs, so the person you talk to is the person who stands behind the result. We serve Scarborough, Toronto, North York, Markham, Vaughan and the rest of the Greater Toronto Area, and we hold an A+ rating with the Better Business Bureau.

Commercial Buildings

Commercial buildings take constant exposure: road salt, rain, exhaust residue and foot traffic all work their way into exterior concrete and stone. Regular commercial power washing in Toronto helps shed that buildup before it stains or degrades the surface, and sealing afterward helps the building stay cleaner longer. We clean the exterior of low-rise commercial buildings, along with walkways, entry pads and loading areas. A clean entrance makes a stronger first impression on customers, tenants and employees, and regular washing is a simple form of preventative maintenance that can help avoid bigger repairs later.

Apartments and Condominiums

Apartment and condo properties have a lot of shared surface: walkways, patios, parking areas and fencing. Tenants notice when those areas look neglected, and graffiti or heavy staining can make a whole building feel uncared for. We wash walkways, driveways and parking lots with high-pressure equipment, hand scrubbing where needed to lift salt, dirt and stains. We also clean and seal interlock and natural stone walkways so they hold their colour and resist staining. After cleaning, we can apply a slip-resistant sealer to hard surfaces to help keep walkways safer when wet.

Retail Plazas

Retail plazas depend on a clean, safe property to keep shoppers coming back. Before we start work in a public area, we complete a risk assessment and identify the hazards and precautions needed so customers and employees stay safe. We remove dirt, gum, stains and salt from storefront walkways and parking areas, then offer a slip-resistant sealer for stone and cement surfaces. The result is a plaza that looks maintained and is less slippery when it rains, and we schedule the work at times that cause the least disruption to the businesses on site.

Fences and Decks for New and Existing Subdivisions

Fences and decks are often the first thing visitors see at a subdivision or commercial property, so they need to look as cared for as the buildings themselves. We power wash, stain, seal and paint wood decks, and we clean and seal concrete, stone and brick fencing as well. For new builds, sealing or staining soon after construction helps protect the wood from sun, rain and snow before weathering sets in. For older fences and decks, a thorough wash removes grey weathering, dirt and staining so the surface is clean and ready to seal. For subdivisions that need a consistent finish across many homes, our commercial fence staining keeps the look uniform from lot to lot.

Underground Parking Garage Cleaning

Underground parking garages collect salt, oil, exhaust soot and tire marks that ordinary sweeping does not remove. We power wash garage floors to lift that buildup, then apply the appropriate sealer or coating so the concrete is easier to keep clean. Regular cleaning also helps protect the concrete from the salt and moisture that cause spalling and cracking over time. We can work floor by floor or in sections so the garage stays partially open while we clean.

Gum and Graffiti Removal

Gum and graffiti are two of the most visible forms of mess on a commercial property, and both send the wrong message to customers and tenants. We remove gum from walkways and plazas and take graffiti off concrete, brick and stone surfaces, including fences and building exteriors. Because the surface is cleaned and restored rather than simply painted over, the area looks consistent when we are done. Prompt removal is also one of the simplest ways to discourage repeat tagging and keep the property looking managed.

WSIB Compliance

Seal Tech is WSIB compliant, which means our crews are covered by workplace safety insurance while they work on your property. That protection matters on commercial sites, where a property manager should not be left responsible if a worker is hurt. We also complete a risk assessment before jobs in public areas and choose cleaning products and procedures that are safe for the surrounding property. Compliance and safe work habits are part of why commercial customers trust us with occupied buildings, plazas and parking structures.

Commercial Power Washing Toronto Property Managers Can Schedule Around Tenants

We know a commercial property cannot simply shut down for a cleaning. We work with property managers to plan commercial power washing Toronto tenants and shoppers barely notice, using early mornings, weekends or section-by-section work so everyone can go about their day. Before we start, we confirm access points, where to stage equipment and how to keep walkways usable. We also give property managers a clear picture of the timing up front, so there are no surprises partway through the job.

Frequently Asked Questions

How long does commercial power washing take?

It depends on the size of the property and how many surfaces we are cleaning. A single storefront walkway can often be done in a morning, while a plaza, condo complex or parking garage is usually scheduled in sections over a few days. We give you a clear timeline with your free written quote.

How long does the surface need to dry before sealing?

We power wash first, then let the surface dry before applying any sealer. Concrete and stone need a dry window before sealing, and how long depends on the weather and how porous the surface is. Sealing a surface while it is still damp stops the sealer from bonding properly and shortens its life.

How long does the sealer last?

It depends on traffic, sun exposure, salt and how the surface is used. Walkways, parking areas and other high-traffic surfaces generally need resealing more often than walls and fences. We can look at your property and recommend a realistic resealing schedule rather than a one-size-fits-all answer.

Do we need to do anything to prepare?

Not much. Clear the area of movable items such as planters, mats and loose equipment so we can reach the full surface. We handle the rest, including protecting nearby surfaces and planning how to keep walkways and entrances usable while we work.

Can you work in rain or cold weather?

Power washing can be done in most conditions, but sealing needs a dry surface and a reasonable temperature to cure properly. If the forecast calls for rain or freezing temperatures, we will reschedule the sealing portion so the finish is not compromised.

What happens during the visit?

We arrive, review the job with you, set up our equipment and complete a risk assessment where needed. We wash the surfaces, let them dry, apply the sealer or coating if it is part of the job, then walk the property with you to make sure you are happy with the result.
