Water Damage Restoration in Cape May, NJ

The Weather Service runs two instruments here and they watch different water. CMAN4 is in the Delaware Bay; CAPN4 is in Cape May Harbor, round the point. The bay gauge calls 6.7 feet above mean lower low water minor flooding, 7.7 moderate and 8.7 major. The harbour gauge sits half a foot lower at every step: 6.2, 7.2 and 8.2. Neither publishes an action stage.

Both had their records set on one date in the middle of a January, and it was not a hurricane. On 23 January 2016 the bay gauge reached 8.98 feet and the harbour gauge 9.36 feet — the highest readings on a 57-entry crest list going back to 1972 and a 34-entry list going back to 2000 respectively. Sandy is second on both, at 8.89 and 8.67 feet. Behind Sandy on the bay gauge come 8.81 feet on 27 September 1985 — Gloria, the storm that wrote this city's worst year — and 8.67 feet on 25 October 1980. The bay gauge's list, at 57 crests, is among the longest published anywhere in New Jersey, tied with the Rockaway River gauge at Boonton and behind only the Atlantic City ocean front, Sandy Hook and Sea Bright.

The statements the two gauges publish are more useful than the records, and they overlap in a way worth knowing about. The harbour gauge publishes this at 7 feet: "Flooding begins on the access roads to the Ocean Drive bridge between Wildwood Crest and Cape May (Cape May County Route 621). Flooding begins along Beach Avenue, New Jersey Avenue and Wilmington Avenue in Cape May. Flooding begins around the Elmira Street bridge in Cape May. Flooding begins near Myrtle Avenue in West Cape May." The bay gauge publishes those same four sentences, word for word, at 7.5 feet. Same roads, same order, half a foot apart, because the two instruments are measuring different water.

Lower down, each has something the other does not. The bay gauge at 7.3 feet: "Flooding begins along Schellengers Landing Road and along Wilson Drive in Lower Township around NJ Route 109. Flooding begins along Washington Street, Yacht Avenue and Texas Avenue in Cape May." The harbour gauge carries that same pair at 6.8 feet and adds Park Boulevard in Wildwood Crest. And the bay gauge alone publishes the one statement about the western shore, at 6.9 feet: "Flooding begins along the Delaware Bay shoreline from Reeds Beach to North Cape May."

Above those readings both gauges switch to the Weather Service's standard coastal text, which is the same on every tide gauge along this shore with the town names changed. The sentences that teach you anything are the low ones.

More than a quarter of the housing here was built in 1939 or earlier and more than two-thirds before 1980, which puts almost everything in this city on the wrong side of both the federal lead-paint line and the years when asbestos was still routinely laid into flooring, mastic and pipe insulation. Those obligations are identical in every New Jersey municipality and are set out in full on the hub. What is particular to Cape May is how often they apply and how much is at stake in the removal, because in a building of this age the material that gets cut out is frequently original.

That sets up the decision that dominates the work here. In a modern house the question at the base of a wet wall is where to cut. In a nineteenth-century one it is whether to cut at all, and the answer depends on what the material is. Old-growth softwood framing, lath and lime plaster, and heart-pine flooring behave very differently in water from gypsum board and engineered timber: they absorb a great deal, they release it slowly, and they tolerate having been wet far better than modern materials do — provided they are actually dried rather than sealed up damp. The failure mode is not swelling, it is rot arriving quietly a year later in a cavity nobody opened.

So the sequence in an old Cape May building is slower and more instrument-led than it is elsewhere. Get the water out, get out whatever is genuinely unsalvageable, then open enough of the assembly to move air through it and take readings in the same places on the same schedule until they stop moving. A plaster wall that reads dry at the surface after two days can still be holding water in the lath behind it, and the only honest way to know is a meter and a second visit rather than a hand and an opinion.

Two more local facts shape the job. Roughly one claim in six here is on a non-residential building — the shops, the guest houses and the restaurants along the front and the walking streets — where the ground floor is the business and the drying happens around trade or instead of it. And the water is usually tidal rather than clean, which means the category of the water gets settled by inspecting the water and the building, not by reading a forecast, and that determination decides what leaves in a skip rather than being dried in place.

Finally, anything that changes the appearance of a building in the historic district is a preservation question before it is a construction one, and this city's rules are unusually specific about windows, doors and cladding. We have written that up separately on our Cape May windows and glass page; it is worth reading before a rebuild scope is agreed, because it can decide what the replacement material has to be.
