Preventing Frozen Pipes at Work: How Businesses Can Help Reduce Winter Damage and Downtime

Why Frozen Pipes Can Be a Serious Risk for Businesses

Winter weather doesn't just bring snow and wind. Depending on where you live, it also brings freezing temperatures that can affect your workplace in costly ways. A significant seasonal risk is frozen pipes. When water in a pipe freezes, it expands. That pressure can cause pipes to crack or burst, sending water into office spaces, warehouses, production areas, electrical rooms, or customer-facing areas.

Water damage is a common and expensive commercial property claim during the winter months. Even a small crack in a pipe can release hundreds of gallons of water in minutes, potentially leading to damaged equipment, ruined inventory, electrical hazards, slippery floors, and operational downtime.

Frozen pipes aren't just a facility problem; they're a bottom-line problem. That's why proactive prevention is one of the smartest winter steps a business can take.

Where Frozen Pipes Tend to Occur in Commercial Buildings

While every workplace is unique, frozen pipes tend to occur in the same types of areas:

Cold or Drafty Areas

• Basements
• Crawl spaces
• Utility rooms
• Warehouses
• Loading docks
• Mechanical rooms

These areas typically experience more outdoor air exchange and less consistent heating.

Exterior Walls and Uninsulated Spaces

Pipes routed near outside walls or windows are more vulnerable, especially if insulation is missing or thin.

Vacant or Low-Traffic Areas

Offices or sections of a building that aren't regularly monitored can drop in temperature without anyone noticing.

Unheated or Partially Heated Spaces

Storage areas, attics, sheds, garages, and annexes commonly host piping for fire suppression, restrooms, or break rooms.

Understanding your building's cold spots can help you prioritize where preventive measures matter most.

How to Help Prevent Frozen Pipes at Work

Preventing frozen pipes is a combination of building maintenance, monitoring, and good winter preparedness. Below are steps businesses of all sizes can take:

1. Maintain Adequate Heat Throughout the Building

Keeping indoor areas above freezing is essential.

• Maintain thermostats at 55°F or higher—even during closures or overnight.
• Avoid drastically lowering heat in unused areas as a cost-saving measure.
• Ensure HVAC systems receive seasonal maintenance so they can keep up with temperature drops.
• A few degrees of warmth can make the difference between safe pipes and a costly water leak.

2. Insulate Vulnerable Pipes

Insulation is one of the simplest and most effective prevention tools.

• Use pipe insulation sleeves, especially in cold rooms or along exterior walls.
• Seal gaps around foundations, door frames, windows, and wall penetrations to reduce drafts.
• For severe climates, consider heat tape or heat cables designed to keep pipes warm.
• Insulated pipes retain heat longer and freeze less quickly.

3. Let Water Drip When Temperatures Plunge

A slow trickle keeps water moving, reducing the chance of freezing.

For businesses, this matters most when:

• Temperatures fall below 20°F
• Your building closes for a weekend or holiday
• Extreme cold snaps are forecasted
• Maintenance teams are unavailable

It's a simple action that helps relieve pressure before ice can build.

4. Open Interior Doors for Better Air Circulation

When pipes are inside walls or cabinets—such as breakroom sinks, restrooms, or kitchenette plumbing—airflow helps warm them naturally.

• Encourage staff or facilities teams to open:
• Cabinet doors
• Mechanical room doors
• Storage room doors with plumbing inside
• Warm air movement reduces temperature drops in localized areas.

5. Keep Cold Air Out

Even small openings can let frigid air reach pipes.

Check for and seal:

• Cracks in walls and foundations
• Gaps around utility line penetrations
• Loose or damaged weatherstripping
• Open dock doors staying up longer than necessary
• Poorly insulated overhead doors in warehouses

Every seal and insulation upgrade can add an extra layer of protection.

6. Monitor and Maintain Fire Protection Systems

Many commercial buildings have fire suppression systems routed through areas where temperatures can fluctuate. Preventing frozen sprinkler lines is crucial because a burst line could release far more water than a standard pipe.

Facilities teams should:

• Maintain heat levels in mechanical and overhead areas
• Inspect dry systems and ensure dry pipe valves function correctly
• Monitor antifreeze levels where applicable
• Ensure attic spaces, mezzanines, and stairwells stay above minimum temperatures

Regular winter checks can help prevent costly system failures.

How to Tell if Pipes Are Frozen

Recognizing the signs early can help prevent a costly rupture. Watch for:

• Little or no water flow: A sudden trickle—or no water at all—is the most common indicator.
• Frost or ice on exposed pipes: Any visible frost in cold areas like basements or utility rooms is a warning sign.
• Unusual odors: Blocked pipes can push smells back through sinks or floor drains.
• Cold or bulging spots on walls: Pipes freezing behind walls may cause cold patches, warping, or dampness.
• Strange noises: Banging, clanging, or gurgling sounds can signal pressure building inside frozen lines.

If you notice any of these symptoms, take action quickly to help reduce the risk of a burst pipe.

What to Do if a Pipe Freezes

Quick, safe steps can include:

• Turn off the main water supply.
• Thaw accessible pipes.
• Open faucets to restore movement once ice clears.
• Contact a licensed plumber or facilities professional.
• Document any damage for insurance purposes.

The faster a pipe is thawed, the lower the chances of a burst. Acting fast—shutting off water, warming pipes safely, or calling a professional—can help prevent a rupture.

How to Thaw Frozen Pipes

If you suspect a pipe is frozen, acting quickly—and safely—can help prevent it from bursting. Here are some tips:

• Turn on the faucet: Even a small trickle helps relieve pressure as the pipe warms.
• Apply gentle heat: Use a space heater, heating pad, warm towels, or a hair dryer on low. Never use open flames or torches.
• Start closest to the faucet: Warm the pipe section nearest the faucet first, then work your way back toward the frozen area.
• Open cabinet doors: Let warm air circulate around kitchen or restroom pipes hidden in cabinets.
• Increase building heat: Raise the thermostat to help warm cold rooms or wall cavities.
• Know when to call a professional: If you can’t locate the frozen section, can’t safely access it, or the pipe won’t thaw, bring in a licensed plumber.

If a pipe has already cracked or you see water leaking, shut off the main water supply immediately and contact a professional before thawing further.

How Frozen Pipes Can Affect Business Insurance

While the terms and conditions of each policy vary, generally, most standard commercial property insurance policies (or a business owner's policy) cover sudden and accidental damage resulting from events like freezing pipes. However, coverage might be denied if losses result from negligence, such as inadequate heating maintenance or ignoring known issues.

To fully understand the extent of coverage, including any exclusions or maintenance requirements, it's crucial to review your policy terms carefully. Consulting with an insurance advisor can also offer detailed insights tailored to your specific policy.

Frozen pipes can result in:

• Water damage claims
• Inventory loss
• Equipment replacement
• Temporary closures
• Business interruption

Consulting with an insurance advisor can help you understand what your policy includes and whether you need additional coverage such as:

• Business interruption insurance
• Equipment insurance
• Commercial property insurance endorsements
• Flood insurance

Conclusion: Winter Protection Starts with Preparation

Frozen pipes may seem like a simple maintenance issue, but the fallout can be significant, especially for businesses that rely on technology, inventory, customer access, or tight production schedules. By taking proactive steps, improving insulation, maintaining heat, and knowing the warning signs, you can help protect your workplace from costly winter damage and unexpected downtime.
