New Haven Water DamageRestoration

New Haven's housing is mostly old, and that matters more than almost anything else on a water call. The city covers only about 17 square miles, so much post-1950 building went to neighboring towns and the older stock stayed.

Key facts: New Haven

  • The city covers only about 17 square miles, so much post-1950 building went to neighboring towns and the older stock stayed.[1]
  • The 1938 hurricane, Carol and Gloria all hit this area, so low streets near the water deserve a flood policy check before storm season.

Plaster ceilings: dry it or take it down?

Wet plaster on wood lath stains and softens but often holds together and can dry where it is.[5] A sagging ceiling is another matter, because the keys holding it to the lath may have failed. Stay out from under it. Tap nearby areas: a hollow sound suggests the bond has let go.

Test before anyone cuts

Buildings of this age can contain lead paint and asbestos, so opening a wall without checking can spread a worse problem than the water.[3][4] Ask the contractor how they test before demolition and how they contain the work.

Harbor and Quinnipiac exposure

New Haven faces the Sound at the head of its harbor, and the Quinnipiac reaches that harbor east of downtown.[1][2] The 1938 hurricane, Carol and Gloria all hit this area, so low streets near the water deserve a flood policy check before storm season.

New Haven home checklist from these records

  • Don't rely on recent quiet years. Only 4% of New Haven County claims date from 2015 or later, so older floods still show what can happen.
  • Insulate exposed pipes before 20-plus hard-freeze nights arrive, and know your main shutoff.
  • Test any sump pump before December, since New Haven averages 12 days a year with an inch or more.
  • Keep dated photos of each room. After Hurricane Sandy, 1,779 insured New Haven County owners filed claims at about the same time.

What to tell the New Haven contractor

  • The age of the building, if you know it
  • Whether the wall or ceiling is plaster or drywall
  • Whether any ceiling is sagging

Questions

New Haven water damage questions

Can wet plaster in a New Haven home be saved?

Often, yes, if it is still bonded to the lath. Sagging, bulging or hollow-sounding sections usually need removal.

Should I worry about lead after a leak?

In a pre-1978 building, assume lead paint may be present until tested, and keep children away from peeling or cut surfaces.[3]
