Why Frozen Pipes Are Dangerous
When water freezes inside a pipe, it expands and pushes against the pipe walls. If the pressure builds up too much, the pipe can burst—sending gallons of water rushing into your walls, floors, and ceilings.
A burst pipe doesn’t just cause leaks; it can flood rooms, ruin insulation, short out electrical systems, and lead to mold growth within days. Even if the pipe doesn’t burst, restricted water flow and pressure changes can strain your plumbing system, causing long-term wear.
If left untreated, frozen pipes can:
- Cause expensive water damage requiring wall or flooring replacement
- Lead to mold and mildew, which pose health risks
- Disrupt your entire water supply
- Result in higher water bills due to hidden leaks once pipes thaw
Common Causes of Frozen Pipes
Houston isn’t known for harsh winters, but when a cold front moves in, unprotected plumbing becomes vulnerable. Here’s what typically causes pipes to freeze:
- Poor insulation in walls, crawl spaces, and attics
- Unheated areas, like garages or basements, with exposed pipes
- Sudden cold snaps following warm days (a Houston winter classic)
- Drafts from windows, vents, or foundation gaps
- Improperly sealed outdoor faucets or spigots
Warning Signs Your Pipes May Be Frozen
Catching the problem early can save you thousands in repairs. Watch for these telltale signs:
- Little to no water flow from faucets
- Gurgling sounds when turning on taps
- Frost buildup on exposed pipes
- Bulging or cracked sections on visible lines
- Unusual odors coming from drains or sinks (a sign of blocked pipes)
If you notice any of these issues, it’s time to act quickly—before the pressure causes a rupture.
How Professionals Thaw and Repair Frozen Pipes
Thawing a frozen pipe requires patience, technique, and the right equipment. A professional plumber will:
- Locate the frozen section using infrared tools or pipe inspection cameras.
- Shut off the main water supply to prevent flooding in case of a burst.
- Gradually apply heat using heat tape, warm air blowers, or specialized thawing tools.
- Inspect for cracks or leaks once water flow returns.
- Repair or replace any damaged sections of pipe.
- Insulate vulnerable areas to prevent the issue from happening again.
DIY thawing attempts—like using open flames or space heaters—can make matters worse by melting solder joints, damaging PVC, or even starting fires.
Why Timely Repairs Matter
A delayed repair can turn a manageable problem into a full-blown disaster. Quick action:
- Prevents water damage to walls, ceilings, and furniture
- Stops mold growth in damp areas
- Keeps your plumbing system reliable
- Reduces overall repair costs
- Helps conserve water by avoiding waste from leaks or bursts
Even a small crack in a frozen pipe can leak hundreds of gallons of water a day once it thaws—enough to damage drywall and flooring in just hours.
DIY vs. Professional Frozen Pipe Repair
It may be tempting to handle frozen pipes yourself, but without proper training, you can easily cause more harm than good. Common DIY mistakes include:
- Overheating pipes and causing them to burst
- Failing to identify secondary frozen areas
- Ignoring micro-cracks that worsen over time
Professional plumbers, like those at John Moore Services, use advanced tools and decades of experience to identify and fix frozen pipe issues safely and efficiently. They also ensure your plumbing system is insulated and ready for future cold spells.
How to Prevent Frozen Pipes
Prevention is always cheaper than repair. Before the next cold front hits Houston, take these steps:
- Insulate exposed pipes in attics, crawl spaces, and garages
- Seal gaps around windows and foundations to keep cold air out
- Keep faucets dripping during freezing weather to maintain water flow
- Maintain indoor heat above 55°F, even when you’re away
- Disconnect garden hoses and drain outdoor spigots
A few hours of preparation can save you thousands in water damage later.
FAQs About Frozen Pipe Repair
-
How do I know if a pipe has already burst?
You may hear running water behind walls, notice drops in water pressure, or see wet spots on ceilings and floors. If so, shut off your main water valve and call a plumber immediately.
-
Can PVC and copper pipes freeze equally?
Yes—but copper pipes are more likely to burst because they’re less flexible than PVC. Both need proper insulation to stay safe during freezes.
-
Will homeowner’s insurance cover frozen pipe repairs?
Most policies cover sudden water damage from a burst pipe, but not the repair of the pipe itself. Preventive maintenance is key.
-
How fast can John Moore Services repair a frozen pipe?
In most cases, same-day service is available for Houston homeowners, with full repairs completed within a few hours depending on damage severity.
-
How can I prevent frozen pipes in rental properties?
Keep thermostats above 55°F, insulate all exposed lines, and educate tenants about dripping faucets during cold snaps.
