The Room That Keeps Rebuilding Its Problem
Bathrooms are the smallest rooms in a Lethbridge house and the largest share of the regrowth we are called into. The reasons are structural. This city's water arrives already heavy in minerals, so grout and caulk lines rough up faster and hold grit that films over with soap residue — a growth bed, not a smooth wall. Houses here are sealed tight through cold snaps and chinook swings alike, and showers push a cloud of vapour into a room whose ceiling corners run cold all winter. And the exhaust fans in much of the city's housing are either undersized for the room or discharging somewhere nobody intended — a soffit, an attic bay, a duct that fell off the roof cap in a winter windstorm.
Cleaning is fine maintenance; it is not remediation. Spraying the ceiling corner each month is a treadmill, because the cycle that produces the stain — steam, cold surface, trapped air — runs daily and the ventilation that should break it is the broken part.
Our bathroom work reads the room first: airflow at the fan, the actual discharge path, wall cavity condition behind the toilet and along the tub's exterior wall. Removal is contained where demolition happens, surfaces are treated, and the report puts the ventilation correction in writing so the room stays dry after we leave.
