Wet Basements in Center Harbor, NH

Center Harbor is compact, largely seasonal along the shoreline, and sits where Winnipesaukee meets the road to Squam. Its basement work clusters at opening in May, for the same reason the dock work does: nobody was there over the winter.

Why Center Harbor Basements Get Wet

The seasonal-discovery problem is acute in Center Harbor because the town is so heavily seasonal for its size. Whatever happened during the March melt is found in May, and by then a wet crawl space or basement has had weeks of standing moisture in a closed, unheated, unventilated building. That is precisely the condition that produces mould in the framing above, and it is the main reason we push battery-backed sump pumps and simple water alarms on seasonal property here.

Geographically, the harbour-side and Waukewan-side properties sit near a high water table, which puts water at the floor-wall joint rather than down a wall. Higher ground toward the Squam road is a different proposition, with the hillside seep pattern.

The village core holds older housing on stone foundations, and as everywhere in this region those want managing rather than sealing.

Center Harbor Note

On a seasonal Center Harbor property, fit a water alarm in the basement or crawl space even if you have a sump. A cheap alarm that texts you is the difference between a wet weekend in March and a mould problem discovered in May.
