In Laval: Facade washing — soft washing matched to every siding
Laval, across the Rivière des Prairies, lines up houses built from 1975 to 2000 with vinyl fences everywhere. The facade is first read as a material: vinyl, brick, stucco or engineered wood each change the product and the angle.
Siding and Facade Washing in Laval: what the inspection reveals
In Laval, most fences are vinyl and regain their white after a measured degreasing. The black streaks on vinyl are Gloeocapsa colonies, algae feeding on the siding's limestone filler.
The diluted fungicidal treatment works on contact, and the next day's rain finishes carrying off the dead deposits. Soft washing runs under 500 PSI, ten times below the threshold that forces a vinyl joint.
Siding and Facade Washing in Laval: the method, pass by pass
Interlock driveways, common in Laval's newer areas, need a rinse that respects the polymeric sand. The low-pressure wand applies foam from the bottom up, then rinsing runs from the top down.
No pressure bears on stucco or on joints: that is what keeps water from getting in. Treating every two years keeps pale vinyl looking new without any scrubbing.
Siding and Facade Washing in Laval: protecting the result afterwards
The cedar decks of Laval houses turn grey by the fourth winter without oil. Plants at the foot of the wall are watered before and after, because clean water dilutes what runs off.
Every sensitive element is flagged with tape at the quote, then protected at wash time. Light brick recovers its tone after a single twenty-minute contact.
Frequently asked questions
How long does washing a facade in Laval take?
Half a day for a cottage, a full day for a two-storey duplex. Detergent contact time accounts for half the visit.
Does bleach damage vinyl?
Diluted to the right ratio and rinsed the same day, no. It is an overdosed product left unrinsed that yellows siding — never our protocol.
Do windows need to stay closed during treatment?
Yes, while the product dwells, about an hour. The final rinse cleans the frames along the way.
