Wet basements in Larchmont
Larchmont is a village in the Town of Mamaroneck on Long Island Sound, about 18 miles from Midtown. Many of its Victorian cottages from its resort era still stand as homes. The small Premium River runs along Willow and Woodbine Park on the way to the Sound.
Low-lying streets near the water and the Premium River have high groundwater, and older homes may have masonry basement walls. Sump pumps, interior drains and careful attention to grading are the common fixes.
A contractor who serves Larchmont will contact you, inspect the basement and the outside of the house, and give you a written proposal. Look for one that names where the water gets in and why, then recommends a fix that matches: sealing a crack, extending downspouts and regrading, adding a sump pump, or installing an interior drain.
Before the visit, note which walls get wet, how soon after rain it starts and if you have a sump pump. Check that gutters are clear and downspouts discharge away from the house. Those two steps alone fix some basements and help the contractor see what is left.
Ask any contractor working in Larchmont for their Westchester County home improvement license number, proof of insurance, the warranty in writing and where any pumped water will be discharged. If the walls show long horizontal cracks or bowing, ask for foundation crack repair advice and consider a structural engineer before any waterproofing goes in.
