As winter storms move closer to Long Island, homeowners and drivers are shifting into preparation mode to avoid costly damage and dangerous conditions.

Real estate salesperson Ted Kritikos says one of the first steps starts with protecting what you cannot see, including weather stripping.

“Anywhere air can come in, you want to make sure you have a good seal,” Kritikos said, explaining that proper sealing keeps cold air out and heat inside.

Kritikos recommends several simple steps before a storm hits: stocking up on food, checking winter tools like shovels and ice melt, testing smoke detectors, trimming overhanging tree limbs and protecting exposed pipes.

Plumbers say frozen and burst pipes are one of the most common, and expensive, problems during winter storms.

“Everybody should know where their water main is in their house,” said Gregory Martino, of Martino Plumbing. “That’s the difference between a small mess and your house being destroyed.”

Martino says homeowners should shut off outdoor hoses and keep heat set to at least 65 degrees to help prevent pipes from freezing.

Drivers are also urged to prepare before heading out in winter weather.

AAA Northeast’s Robert Sinclair says checking tire pressure and switching to winter washer fluid can help prevent breakdowns on icy roads. If a vehicle does break down, he recommends keeping an emergency kit with warm clothing, extra socks and blankets.

Taking a few minutes to secure your home and car before the snow starts falling can help keep you safe and prepared for the upcoming winter storm.
