Mold Remediation in Burnaby

Heights bungalows still sit over dirt that was never covered. The crawl stays cool and damp, and the joists take that moisture all winter. Edmonds bungalows from that era repeat the pattern. Wipe the wood in March and the fuzz can be back by July, because the soil never stopped feeding it.

Fogging the hatch doesn't dry soil. We contain the opening, remove colonized insulation and any wood that's too far gone, clean what can stay, and move air through the bays until the joists actually dry. If the ground stays open and wet, the return path is still there.

Capitol Hill basements are cut into the slope, and the wet side is the wall against the hill. After a long wet winter the footing keeps the bottom plate damp even when the floor looks fine. South Slope houses do this too. The stain is small. The cavity behind the paint is where the mold is living.

Painting that wall locks the moisture in. We open the wet line, contain the dust, take out colonized board and batts, and dry the plate and the concrete behind it. If the footing is still weeping, the colony has a return path and new drywall won't change that.

In a Metrotown tower the flood is usually the suite above. Water runs down a party wall, soaks the cavity, and the paint on your side looks dull while the paper behind it stays wet. The neighbour may have fixed the supply line. The wall can still be damp enough to grow mold later.

Wiping the stain and fogging the living room leaves that cavity wet. We contain the suite, open the wet section of the party wall, bag the colonized board, and dry the bay. The return path is the leak that started it. If that line is still dripping, the wall gets wet again.

Sullivan sits on the flats, and groundwater reaches the footing when the soil is loaded. It doesn't always show as a puddle. The bottom of the wall stays cool and damp, and mold grows on the plate and the back of the baseboard. A sunny week doesn't stop a footing that wicks.

We don't fog the bungalow and call the smell gone. The wet lower wall gets contained, colonized board comes out, and the plate is dried with air in the cavity. If groundwater is still reaching that footing, we'll say so. One dry-down doesn't hold the water back.
