Graffiti Removal in Quebec City
Chemical Graffiti Removal in Quebec City, Quebec — with 65 freeze-thaw cycles annually and an average winter temperature of -12.8°C, local conditions directly impact graffiti removal methods and costs.
Quebec City's heritage stock (including Vieux-Québec (UNESCO)) typically requires pH-neutral chemical gel (pH 6.5–7.5) with 30–60 minute dwell time — acidic strippers dissolve mortar calcium and leave white efflorescence on stone. We pre-test an inconspicuous patch before treating the visible area, with all rinse water captured to meet local stormwater rules.
Quebec City receives 1230mm of annual rainfall, which causes spray paint to penetrate porous surfaces like stone, heritage materials, brick rapidly — making prompt removal essential before paint bonds permanently.
Under the Règlement de la Ville de Québec sur l'entretien des propriétés, property owners must remove graffiti within 10 days of notification. Our hourly rate in Quebec City ranges from $38–$75.
