Why Pipes Freeze Around Glendale Heights

Winters in DuPage County bring sharp freeze‑thaw swings that push uninsulated or draft‑exposed pipes to the limit. Outdoor hose bibs, garage lines, crawlspace plumbing, and pipes against exterior walls are most at risk. When water freezes it expands by about 9 percent, which creates pressure inside the pipe. If that pressure exceeds the pipe’s strength or a weak joint, the line can split.

Two common scenarios cause trouble:

1. Prolonged subfreezing temperatures and wind that chill exterior wall cavities.
2. Sudden cold snaps after mild weather that catch uninsulated runs off guard.

Local trees can also invade shallow lines, and heavy winter road salt plus spring thaws stress older galvanized and cast iron. Even if a frozen pipe has not burst yet, thinning or corroded spots can fail during thawing.

"Summers always does a great job! Professional and polite and answers all of your questions. They came out and got the clog fixed with the best methods."

Safety First: Before You Attempt Any Thaw

Do a quick safety check. A careful start prevents costly water and electrical damage.

1. Find your main water shutoff. Make sure you can access and turn it quickly.
2. Inspect visible sections for bulges, cracks, or frost on the pipe. If you see damage, shut water off and call us immediately at (331) 294-8710.
3. Open the nearest faucet to the suspected frozen section. A small trickle relieves pressure.
4. Move flammables away from the area. Keep space heaters on a stable, dry surface.
5. Use GFCI‑protected outlets. Keep cords and tools dry. Never stand in water while using electric tools.

Summers PHC trains technicians on safe thawing procedures, including starting at the faucet end and working back toward the blockage. This reduces trapped pressure and lowers burst risk.

Tools You Can Use at Home

You do not need specialized equipment to thaw a simple freeze. Gather the following:

1. Hair dryer with a high heat setting and a focused nozzle.
2. Portable space heater or ceramic heater.
3. Towels for moisture and to drape over pipes to hold gentle warmth.
4. Thermometer or your hand to monitor temperature. Warm, not hot, is the goal.
5. Flashlight to inspect dark crawlspaces or cabinets.

Avoid open flames. Do not use a blowtorch, propane heater, or charcoal grill. These can crack pipes, ignite framing, or produce dangerous carbon monoxide.

How To Find the Frozen Section

Follow the symptoms to narrow the search.

1. Turn on cold water at each fixture. No flow or just a dribble signals a frozen supply line.
2. Check typically cold spots first: exterior wall cabinets under sinks, basements, crawlspaces, garages, and unheated additions.
3. Compare temperatures by touch. A section that feels very cold or frosty is the likely freeze point.
4. Listen for hissing or dripping behind a wall. That can mean a split pipe and hidden leak.

If you cannot locate the frozen section, our team uses non‑invasive video inspections for drains and advanced detection tools for supply lines to pinpoint issues with minimal opening of walls.

"Jason was very informative and helpful. He explained everything before he did it, and why he was doing it. I would definitely call and use him again."

Step‑By‑Step: Thawing With a Hair Dryer

This is the gentlest, most controlled DIY method and works well on accessible copper, PEX, or PVC supply lines.

1. Open the affected faucet. Start with cold, then open hot slightly if needed.
2. Set the hair dryer to high heat and low airflow to focus warmth.
3. Start at the faucet end of the frozen run. Warm the pipe evenly, moving slowly in 6 to 12 inch passes.
4. Work back toward the suspected blockage. Do not concentrate heat on one point for more than 15 seconds.
5. Use a towel draped loosely over the pipe to hold gentle warmth. Keep the towel dry.
6. Continue until water flows steadily. Let water run for a few minutes to clear slush.

Tips for different materials:

• Copper: Heats quickly. Keep the dryer moving to avoid overheating soldered joints.
• PEX: More flexible and tolerant to freezing but can kink if overheated. Maintain space between nozzle and pipe.
• PVC: Low heat only. Excessive heat can soften or warp fittings.

Step‑By‑Step: Thawing With a Space Heater

A space heater is ideal for cabinets, small rooms, or crawlspaces where the exact frozen spot is unclear.

1. Clear a 3‑foot radius around the heater. Place it on a level, dry surface.
2. Aim heat toward the wall cavity or cabinet containing the pipe, not directly at the pipe.
3. Open cabinet doors to allow warm air to surround the line.
4. Maintain constant supervision. Keep pets and kids away.
5. Check every 10 minutes. When water begins to trickle, keep heating until full flow returns.

Never leave a space heater unattended. Always follow the manufacturer’s clearance and safety instructions.

What Not To Do

• Do not use open flames. They can ignite framing and damage pipes.
• Do not strike or bend a frozen pipe. Ice is rigid and can crack fittings.
• Do not close the faucet while thawing. Keep it open to relieve pressure.
• Do not overheat PVC or PEX. Gentle, even warming is the goal.

Signs a Pipe Has Already Burst

Knowing the warning signs can save you thousands in water damage.

• Hissing behind a wall followed by loss of pressure.
• New water stains on ceilings or drywall, or paint that bubbles.
• Unexpected sound from the water meter when all fixtures are off.
• A sudden spike in the water bill after a cold snap.

If you suspect a burst:

1. Shut off the main water valve immediately.
2. Turn off the water heater’s cold inlet. For tank‑type gas heaters, set to pilot. For electric, switch off at the breaker.
3. Open low faucets to drain the system.
4. Call Summers PHC at (331) 294-8710 for emergency service. We are available 24/7.

"They removed concrete and gravel to get to a broken cast iron pipe, replaced and lined another 20 feet, and cleaned up very well. I will call them for future needs."

When DIY Is Enough vs When To Call a Pro

DIY thawing is appropriate when:

• You can access the frozen section safely.
• There are no signs of leaks, bulges, or splits.
• You restore flow in under 45 minutes with gentle heat.

Call a professional when:

• You cannot locate the freeze or it sits behind finished walls.
• You see a bulge, crack, or ongoing drip.
• Thawing fails or flow remains weak after warming.
• Multiple fixtures are affected, which suggests a main line issue.

Our licensed specialists use targeted methods that reduce damage and downtime:

1. Non‑invasive video inspections to check drains before digging.
2. Advanced leak detection tools to locate hidden supply breaks.
3. Sectional replacement to fix only the damaged segment with code‑compliant materials.
4. Pipe relining in suitable drain cases to strengthen from the inside without excavation.
5. Hydrojetting to clear ice‑related debris and buildup safely without harsh chemicals.

Preventing Frozen Pipes Next Time

A few low‑cost upgrades protect your Glendale Heights home all winter.

1. Insulate exposed pipes in garages, crawlspaces, and exterior walls with foam sleeves.
2. Seal air leaks around sill plates, hose bibs, and cable penetrations.
3. Add heat tape with a thermostat for problem runs. Follow the manufacturer’s instructions.
4. Let faucets drip during hard freezes, especially on exterior walls.
5. Open cabinet doors under sinks on exterior walls to circulate warm air.
6. Disconnect and drain garden hoses. Install frost‑proof hose bibs where possible.
7. Keep the thermostat at a steady setting, day and night, during cold snaps.

Summers PHC also offers routine pipe inspections. We look for corrosion, weak joints, and hidden risks before leaks develop. We can advise on winterizing exposed plumbing and adding insulation tailored to your specific layout.

Local Insight: DuPage and Northwest Suburbs

Homes in Glendale Heights, Carol Stream, Lombard, and Wheaton often have supply lines routed through garage ceilings or cantilevered sections that cool quickly. Split‑level and ranch homes can hide long runs in exterior soffits. During deep cold, a small drip at the kitchen sink or powder room on an exterior wall can prevent a freeze. If your home has a history of winter clogs, a video inspection can confirm whether roots or an offset joint are compounding the issue.

Frequently Asked Questions

How long does it take to thaw a frozen pipe with a hair dryer?

Most simple freezes thaw within 15 to 45 minutes using gentle, continuous heat. Keep the faucet open. If nothing changes after 45 minutes, call a professional.

Is it safe to use a space heater to thaw pipes?

Yes, if used carefully. Keep a 3‑foot clearance, place it on a dry, level surface, and never leave it unattended. Warm the area, not the pipe directly.

Should I shut off water before thawing?

Keep the faucet open, but leave the main on unless you see leaks or hear hissing. If you suspect a burst, shut the main off immediately.

Can PVC or PEX pipes be thawed with heat?

Yes, with low, even heat. Do not overheat. PEX tolerates freezing better than rigid pipe, but fittings and valves can still crack.

What if a pipe bursts while I am thawing it?

Shut off the main water valve, protect electrical circuits if needed, and call Summers PHC at (331) 294-8710. We provide 24/7 emergency service.
