Local risk profile
Schenectady County covers 205 square miles of eastern New York, with about 160,369 residents and 71,244 homes. Schenectady is the county seat; Rotterdam, Niskayuna and East Glenville are the next largest communities. It has some of the oldest housing in the state: the median home went up in 1956.
72/100 Water Damage Risk Index: High Schenectady County ranks 3 of 57 New York counties. See the statewide ranking and method.The three factors where Schenectady County ranks highest compared with other New York counties.
For frozen pipes, Schenectady County is a typical New York county, which is still plenty. In the 2015–2024 record the county logged about 56 nights a year at or below 20°F (24th of 57) and 138 below freezing. Twenty degrees is roughly where uninsulated pipes start to freeze.
Cold snaps are the real risk. The worst in the record lasted 28 days below freezing (ending February 2015), and the low bottomed out near -14°F on February 14, 2016.
Most freezing nights fall from November to March, peaking in January. Disconnect garden hoses and shut off outdoor spigots before the first hard frost, and keep the heat at 55°F or higher if you'll be away.
On average the first fall freeze arrives around Oct 25 and the last spring freeze around May 1.
Heavy rain is a bigger factor here than in most of New York. Of roughly 40.7 inches of yearly precipitation, the damage comes from the 6.8 days a year with an inch or more, ranked 19th of 57. August, September and October see the most. The single wettest day in the record: 3.14 inches, September 30, 2015. Multi-day storms matter most for basements; the wettest three days on record here totaled 3.9 inches (through October 1, 2015).
About 102 days a year swing from below freezing at night to above freezing by day. Those freeze-thaw cycles feed ice dams on roofs, open cracks in foundations and driveways, and stress pipes that are already marginal.
Housing
75% of homes in Schenectady County predate 1980, above the New York county median of 66.8%, which ranks 9th of New York's 57 counties.
In Schenectady County 57% of homes are older than 1960. If yours is one of them and the plumbing has never been replaced, expect galvanized steel supply pipe and cast iron drain lines, the two materials most likely to fail quietly.
Renters occupy 36% of homes. If you rent, the building is usually the landlord's to repair, but your belongings are only covered by renters insurance.
Beyond water
Schenectady County averages 16 warm, muggy nights a year (lows of 65°F or more) and gets the most rain in August. Mold grows when indoor humidity stays above about 60%, the EPA's ceiling. A basement dehumidifier set to 50% and drying anything wet within 24 to 48 hours prevents most problems.
Mold remediation: what to expectBy main heating fuel, Schenectady County homes break down as 69% utility gas, 18% electric, 5% propane and under 1% wood. Fires here are likelier to start in the kitchen or the wiring than in the furnace. After any fire, keep the HVAC off until ducts are checked, or soot will travel through the house.
