Opening up after six weeks

Illustrative example. Not a real job or customer.

Illustrative example. A host's townhome in LoHi has a garden-level bedroom and bathroom partly below grade. After six weeks without bookings, the cleaner arrives the day before a new guest and reports a musty, slightly sewer-like smell in the lower bedroom and bath.

  1. The cleaner runs water in the lower bathroom sink, shower and the laundry floor drain. The sewer note fades within minutes.
  2. The musty smell remains. The cleaner pulls the bed away from the exterior wall and finds the carpet edge damp along the baseboard.
  3. The host checks the bathroom on the other side of the wall and finds a slow drip at the toilet supply valve, which has wet the bottom of the shared wall.
  4. A plumber replaces the valve that afternoon. The host sets up a dehumidifier and fans in the bedroom overnight and moves the guest's arrival to a later check-in time, with their agreement.
  5. By the next afternoon the carpet edge is dry and the smell is faint. The host books a moisture check of the wall for after the guest's stay.

The guest arrived to a fresh room. The moisture check found the wall had dried without needing removal, because the leak was caught within weeks rather than months.

Two smells, two causes

Sewer-like smell

  • From the dry shower and floor drain
  • Gone after running water
  • Prevented by running drains during gaps

Musty smell

  • From damp carpet and drywall
  • Stayed after drains were filled
  • Needed the leak fixed and drying

Why gaps hide problems

When guests use a unit every few days, small problems get noticed: a running toilet, a wet bath mat, a door left open. During a long gap, nobody flushes, showers or opens the windows, the heat may be set low, and a slow leak can soak into carpet and drywall undisturbed. Garden-level rooms with cooler walls are where musty smells show up first.

A visit every week or two during quiet stretches, even a short one, catches most of these before a guest does.

Quiet-stretch visit list

  • Run every drain and flush every toilet.
  • Look under sinks, behind toilets and around the water heater.
  • Smell lower-level rooms with the door closed for a few minutes.
  • Check the thermostat is holding a safe temperature.
  • Open blinds or windows briefly to air out if the weather allows.

Common questions

Would an air freshener have solved it?

It would have covered the smell for the guest's first hour and left the leak running. Finding the source mattered more than the smell itself.
