Question 1

What is the difference between soft washing and pressure washing?

Accepted Answer

Soft washing uses low pressure combined with specialized detergents to deeply remove mold, algae and dirt. It is ideal for house siding, roofs and delicate surfaces. Pressure washing uses high mechanical pressure to dislodge embedded dirt, and is better suited to robust surfaces like concrete, asphalt and stone. At Aqua-Net, we choose the appropriate method based on the surface to clean to guarantee optimal results without damaging your property.

Question 2

How often should I have my house washed?

Accepted Answer

We recommend having your house washed once a year to maintain its appearance and protect the siding. However, if your property is located near a body of water, in a wooded area or heavily shaded, washing every 6 months may be necessary as humidity promotes mold and algae growth. On Montreal's North Shore, the humid climate and significant temperature variations accelerate contaminant buildup. Regular washing extends your siding's lifespan and prevents costly damage.

Question 3

How much does house washing cost on the North Shore?

Accepted Answer

The cost of house washing varies based on several factors: house size, siding type, dirt level, accessibility and additional services (roof, deck, driveway). Generally, a residential house wash on Montreal's North Shore costs between $300 and $800. We offer combined packages that include multiple services at a reduced price. The best way to get an accurate price is to request a free quote, which we provide in 24h with no obligation. Call us at (514) 506-7043 or fill out our online form.

Question 4

Why are there black streaks on my roof?

Accepted Answer

Black streaks on your roof are caused by a bacterium called Gloeocapsa Magma, which feeds on the limestone granules in asphalt shingles. This bacterium, along with moss and lichen, thrives in humid climates like Montreal's North Shore. Besides the unsightly appearance, these organisms degrade your shingles, reduce their lifespan and can cause leaks. Aqua-Net's soft roof washing eliminates these organisms at the root with a biocidal treatment, without using high pressure that would damage your shingles.
