SEASONAL INSPECTION RECOMMENDATIONS FOR LONG ISLAND WATERFRONT

Spring — March through May

Water roughly 40 to 58°F. Growth minimal. The best structural work window of the year, and the cleanest bucket test window since evaporation is low.

• Walk the lawn edge behind bulkheads for settling, depressions, or sinkholes indicating washout
• Inspect dock framing, through-bolts, cleat mounts, and pile caps for winter displacement or freeze splitting
• Sight down the pile line for members at differing heights or out of plumb — the signature of ice jacking
• Inspect thru-hull fittings, ball valves, transducers, and strainers before commissioning
• Pressure test pool lines before filling; inspect plaster or liner for frost damage
• Inspect and service moorings before boats go on, not after

Summer — June through September

Water roughly 65 to 74°F. Peak biofouling, peak vessel traffic, peak swim-area exposure.

• Interim hull cleanings on a regular cycle rather than one heavy scrub
• Mid-season anode check and replacement at 50 percent consumed
• Running gear inspection and line entanglement removal
• Clear intakes and strainers before growth becomes an overheating event
• Inspect swim line anchors, float spacing, and hardware
• In-season pool dye and pressure testing

Fall — October through November

Water roughly 50 to 65°F and dropping. Atlantic hurricane season runs through November 30, with nor'easter exposure building.

• Deploy bubblers or de-icers around deep-water pilings to prevent ice lock and ice jacking
• Clear bulkhead weep holes of debris before the ground freezes
• Pool line blowout with high-volume air, winter expansion plugs, non-toxic antifreeze
• Pre-haul-out hull inspection while there is still yard time to schedule work
• Pull swim lines, anchors, and hardware before ice forms
• Take baseline photographs so spring storm damage is provable

Winter — December through February

Water roughly 38 to 45°F. Peak ice risk.

• Confirm de-icers are running and open water is holding around vulnerable piles
• Post-storm inspections after any significant nor'easter, particularly on structures already flagged
• Turn fall inspection findings into scoped, bid-ready work before the season opens
