Wet Basements in Moultonborough, NH

Moultonborough's enormous shoreline means a large number of properties sit close to the water table, and a high proportion of them are seasonal — which means nobody is there in March when the melt arrives and nobody sees what happens until May.

Why Moultonborough Basements Get Wet

The seasonal pattern creates a particular Moultonborough problem: damage that runs unobserved for months. A sump pump that failed in January is discovered in May, by which point the basement or crawl space has been wet since the melt. A crack that started weeping in March has been weeping until somebody opened the door. And in a closed, unheated building, weeks of standing moisture with no ventilation produce exactly the conditions that grow mould in the framing above.

That is the argument for two things on seasonal property here: a sump pump with a battery backup and an alarm, and somebody checking the building during the melt. Power outages in a Lakes Region March are routine, and a sump pump without backup is a sump pump that will fail on exactly the night it is needed.

Back toward the Ossipee foothills, the picture changes to hillside water — seasonal seeps and runoff moving downslope against uphill foundation walls.

Moultonborough Note

On a seasonal Moultonborough property, a sump pump without battery backup is a coin toss. Outages during the March melt are routine, and the pump fails on the one night that matters — with nobody there to notice for two months.
