Moss makes your home look unkempt

Moss clinging to siding traps moisture against the surface. This dampness can cause the material to warp, crack, or rot, especially in our wet climate. Left unchecked, the issue spreads to trim and window frames.

Walkways, patios, and driveways also collect algae and moss, becoming slick and hazardous. A professional pressure washing restores traction and brightens the entire property.

Effective Grime Removal

The green-black buildup on your siding traps moisture and slowly damages paint and wood. A thorough exterior wash removes it all before rot or stains can set in.

Our team uses soft washing and hot water to lift moss, algae, and dirt without harming the siding. The result is a clean exterior that looks freshly painted—even when it isn’t. For homeowners in the Lower Mainland, pressure washing in Vancouver is the quickest way to improve curb appeal.

Importance for Coquitlam Homes

Coquitlam’s mix of coastal mist and mature trees creates constant damp shade on north-facing walls and walkways. This makes moss and slippery biofilm a regular problem for local property owners.

Older wood-sided homes and newer HardiePlank houses both collect the same stubborn film. A seasonal rinse protects the siding and keeps concrete paths safe—especially on sloped driveways that can freeze lightly in winter. We’ve seen the difference it makes for Coquitlam homes year after year.

Soft Washing Process

Soft washing uses a low-pressure spray with a sodium hypochlorite solution. This solution removes moss and algae from the root. It sits for ten to fifteen minutes before we rinse it off with water at under 500 psi. For oily stains on driveways, we use hot water extraction. This method lifts grime without harming the concrete.

On cedar siding, we use a wider fan tip and keep the nozzle moving. This prevents damage to the wood fibers. For HardiePlank, we apply a gentle soft wash to protect its factory finish. North-facing walls often need extra algaecide treatment to stop regrowth in Coquitlam’s damp climate.

Managing Moisture in Coquitlam

Moss and biofilm hold moisture against siding. This can block the capillary gap that lets water evaporate. If not cleaned, it can cause paint failure and wood rot, especially on the north walls in Coquitlam that get a lot of rain. Regular cleaning removes this organic layer and helps the siding shed water.

When washing, we spray at a downward angle to stop water from getting behind lap joints or flashing. Around windows and doors, we use lower pressure and a fine spray to protect the sealants. In a place with frequent wind-driven rain, keeping the building dry during cleaning is very important.

Coquitlam Pressure Washing Regulations

From May 1 to October 15, outdoor pressure washing in Coquitlam must follow regional water use restrictions. During Stage 3 limits, washing home exteriors, driveways, and patios is allowed only for health and safety reasons, to prepare for painting or sealing, or if a commercial service performs the work. If restrictions tighten, non-essential residential pressure washing may be further limited.

Coquitlam’s Noise Control Bylaw No. 1233, 1982 limits pressure washing noise to Monday to Friday from 7 a.m. to 8 p.m. and Saturday from 9 a.m. to 6 p.m. Homeowners can wash during those hours on Sundays and holidays, but contractors cannot operate for profit on those days. We schedule all our exterior washing within those permitted hours.

The City’s Good Neighbour Construction guidance clarifies that any noises from operating machines or construction equipment fall under construction noise rules. Loud pressure washers used for exterior cleaning must follow the same permitted hours: 7 a.m. to 8 p.m. on weekdays and 9 a.m. to 6 p.m. on Saturdays, with homeowners allowed similar hours on Sundays and holidays.
