High-Pressure Cleaning Services in Montreal
Industrial-grade pressure washing that strips dirt, mould, algae and grime from driveways, patios, siding and building exteriors — surfaces restored to their original condition.
Surfaces That Look New Again
Pressure washing (power washing) uses high-pressure water spray to remove accumulated dirt, mould, mildew, algae, paint chips and grime from exterior surfaces — restoring original appearance without chemicals or abrasion.
Montreal winters leave their mark: salt stains on concrete, mould on siding, algae on patios. Spring reveals months of accumulated grime that no garden hose can touch. Professional pressure washing uses industrial-grade equipment to strip years of build-up in hours.
Our technicians calibrate pressure levels and nozzle types for each surface — too much pressure damages wood and soft stone, too little fails to clean. The right equipment and expertise make the difference between a surface that looks washed and one that looks new.
Why Pressure Washing Pays for Itself
Property value. A clean exterior makes an immediate impression — critical for homes going to market, businesses greeting customers, or rental properties between tenants.
Preventive maintenance. Mould and algae eat into surfaces over time. Regular pressure washing prevents the degradation that leads to repainting, resurfacing or replacement.
Health and safety. Mould, mildew and algae create slip hazards on walkways and degrade air quality near building entries. Removal eliminates both risks.

Frequently Asked Questions
Will pressure washing damage my siding?
We calibrate pressure for each material. Vinyl and stucco require lower pressure than brick or concrete. Our technicians know the limits for every surface type.
How often should I pressure wash?
Annually for most properties. Montreal's salt and freeze cycles mean spring washing is especially important for driveways and walkways.
Do you use chemicals?
We use biodegradable cleaning solutions for mould and algae pre-treatment, then rinse with clean water. No harsh chemicals remain on your surfaces.
Can you clean my roof?
We offer soft-wash roof cleaning — low-pressure chemical application that removes algae without damaging shingles. High-pressure roof cleaning is not recommended.
What areas do you serve?
All of Montreal island, Laval, Longueuil and the South Shore.
