How to Winterize Your Plumbing in Maryland: A Step-by-Step Guide

Winter in Maryland brings beautiful snowscapes, but it can also come with frozen pipes, burst plumbing, and expensive water damage if your home isn’t prepared. A little preparation ahead of winter can go a long way to prevent frozen pipes and plumbing emergencies. In this guide, we’ll show you how to winterize your plumbing, when to get started, and why F.H. Furr’s plumbing services are the best choice for your peace of mind this winter.

Why Winterizing Matters

Frozen pipes can crack or burst under pressure, sending water flooding into your home and causing significant damage. This risk is even higher in older Maryland homes with drafty basements, crawlspaces, or exterior walls with little insulation.

By winterizing your home, you can avoid:

  • Expensive pipe repairs and drywall restoration
  • Water damage to floors, furniture, and valuables
  • Emergency plumbing calls during peak winter months
  • Extended disruptions to your water supply

When to Start

It’s best to start your frozen pipe prevention efforts early—before temperatures dip below freezing. In Maryland, this usually means preparing in late October or early November. Give yourself enough time to inspect key areas, gather materials, and schedule any necessary repairs with your trusted local plumber. Once the first cold snap hits, frozen pipes can become a reality fast—especially in under-insulated homes or vacant properties.

Key Steps: How to Protect Pipes in Winter

Use the checklist below to prepare your plumbing before winter hits:

 

Winter Plumbing Prep Task

Why It Matters

 

Insulate exposed pipes in unheated areas.

Prevents freezing in basements, attics, garages, and crawlspaces.

 

Disconnect and drain outdoor hoses.

Stops water from backing up into pipes and freezing.

 

Shut off and drain outdoor faucets.

Protects spigots and attached lines from damage.

 

Seal gaps around pipes with caulk or insulation          

Keeps cold air from reaching indoor pipes.

 

Inspect your water heater.        

Ensures it’s operating efficiently before peak usage.

 

Check for slow leaks or drips.  

Even small leaks can worsen in cold weather.

 

Locate your main water shut-off valve.

Being able to shut off water quickly can prevent major damage in case of a burst pipe.

Special Cases & Extra Tips

Some homes need a little extra attention during the colder months. If you’re heading out of town, live in an older property, or have pipes near exterior walls, these tips can help:

Homes with Crawlspaces

Crawlspaces are especially vulnerable during winter, since they’re often poorly insulated and exposed to outside air. Pipes running through these areas can freeze quickly when temperatures drop. To protect them, seal vents with insulated covers and consider adding rigid foam or thermal insulation along the crawlspace walls. In especially cold conditions, safe heating options like heat tape or low-wattage pipe heaters can offer added protection.

Older Homes

Maryland’s older homes often have less insulation and aging plumbing systems, which makes winter prep even more important. Pipes located in exterior walls or unheated areas are particularly at risk for freezing. Installing foam pipe insulation is a simple and effective way to reduce that risk. It’s also a good idea to schedule a plumbing inspection to identify any outdated components or minor leaks before cold weather makes them worse.

Heading Out of Town for the Winter?

Leaving your home unoccupied during winter? Don’t skip plumbing prep. Shut off your main water supply and open faucets to drain the lines. Add a small amount of RV antifreeze to toilets and drains to keep standing water from freezing. If you’ll leave the heat on, keep the thermostat at 55°F or higher to maintain a safe indoor temperature. Taking these steps before you go can prevent major headaches while you’re away.
