A lake house has its own problems. Sand and grit get tracked in from the water, humidity keeps bathrooms and closed-up rooms damp, and mildew starts in showers, window frames and around patio doors far faster than it does inland. We treat wet areas with mildew in mind rather than just wiping them, pay attention to window tracks and door frames, and if a house has been shut up for weeks we will tell you honestly whether it needs a deep clean first.
