How do you winterize a Clarksville TN home before the first freeze?
Disconnect and drain outdoor hoses, protect exterior faucets and exposed pipes, service your heating system, clean gutters, inspect the roof and chimney, seal drafts, and keep the home heated during freezing weather. If you will be traveling or leaving Clarksville for a PCS, set the thermostat no lower than 55°F and arrange for someone to check the property regularly.
Clarksville and Montgomery County homeowners often have plenty of notice before winter weather arrives, but the first hard freeze can still catch you off guard. A single night below 32°F may damage an exposed pipe, outdoor faucet, irrigation component, or unprotected backflow preventer.
The most important preparation is simple: complete the plumbing and heating tasks before freezing temperatures arrive. Then address the roof, gutters, insulation, fireplace, and exterior drainage so your home is ready for cold weather, rain, wind, and freeze-thaw cycles.
The City of Clarksville’s cold-weather precautions provide useful local guidance for protecting pipes and maintaining safe indoor temperatures. Here is a practical Clarksville-focused winterization plan.
1. Protect outdoor faucets, hoses, and exposed pipes
Outdoor plumbing is one of the most vulnerable parts of your home during the first freeze.
Before temperatures approach 32°F:
- Disconnect every garden hose from exterior faucets.
- Drain hoses completely and store them in a garage, shed, or other protected location.
- Install insulated faucet covers where appropriate.
- Shut off and drain exterior water lines if your plumbing system has interior shutoff valves.
- Insulate exposed pipes in garages, crawl spaces, basements, and other unheated areas.
- Repair dripping outdoor faucets and visible plumbing leaks.
- Winterize irrigation lines according to the system manufacturer’s instructions.
- Protect irrigation backflow preventers from freezing.
- Keep the water meter lid closed.
- Locate your main household water shutoff valve.
Do not assume that a covered faucet is fully protected if water remains trapped in the connected pipe. Proper draining is important, especially when the line runs through an unheated crawl space or garage.
Clarksville homeowners should also review the City’s backflow, cross-connection, and thermal-expansion guidance before winterizing irrigation equipment or backflow devices.

2. Know what to do during an active freeze
Winterization is not finished when you install an outdoor faucet cover. During an extended freeze, take additional steps to keep vulnerable plumbing warm.
If temperatures are expected to remain below freezing:
- Keep your heat turned on and avoid large temperature changes.
- Open cabinet doors beneath sinks located along exterior walls.
- Keep interior doors open to encourage warm-air circulation.
- Allow a small trickle of water from vulnerable faucets if local conditions and your plumbing setup warrant it.
- Close foundation vents when appropriate for your crawl-space design.
- Seal openings that allow cold air to reach pipes, but do not block required combustion or ventilation openings.
- Check exposed plumbing periodically if temperatures remain unusually low.
If a pipe freezes, do not use an open flame, torch, or other unsafe heat source to thaw it. Shut off the main water supply if you suspect a burst, then contact a licensed plumber.
You should also know how to respond if a water or gas emergency occurs. Keep your utility provider’s emergency numbers and your plumber’s contact information in an accessible location.
3. Service your HVAC system before you need it
A heating system that worked last winter may still need maintenance before the first cold snap. Clarksville homes may transition quickly from air conditioning to daily heating, placing added demand on furnaces, heat pumps, and dual-fuel systems.
Schedule professional HVAC service and ask the technician to inspect:
- Heating performance
- Thermostat operation
- Electrical connections and safety controls
- Ductwork and airflow
- Heat pump operation
- Condensate lines
- Combustion components on gas systems
- Carbon monoxide risks around fuel-burning equipment
Replace or clean the air filter according to the manufacturer’s instructions. A dirty filter can restrict airflow, reduce comfort, increase energy use, and place extra strain on the equipment.
Test the system before freezing weather arrives. Make sure each room receives heat, listen for unusual sounds, and pay attention to unusual odors. If you have a gas furnace or fireplace, verify that carbon monoxide detectors are working and have fresh batteries.

4. Clean gutters and inspect the roof
Gutters are especially important in Montgomery County neighborhoods with mature trees. Leaves, twigs, and roof debris can block drainage and send water toward the foundation.
Clean gutters after most leaves have fallen, then inspect for:
- Sagging sections
- Loose fasteners
- Separated joints
- Cracks or holes
- Damaged end caps
- Overflow marks beneath the roofline
- Clogged downspouts
- Downspouts discharging too close to the foundation
Inspect the roof from the ground using binoculars, or hire a qualified professional if you see missing, cracked, curled, or lifted shingles. Look closely at flashing around chimneys, vents, skylights, and roof penetrations.
Also check soffits, fascia, siding, exterior trim, and porch structures. Small gaps can allow cold air and moisture into the home. Repairing them before winter rain and freezing temperatures can help prevent larger problems.
Do not climb onto a wet or icy roof. If roof work is needed, use an experienced roofing professional.
5. Check insulation and seal drafts
Good insulation helps your heating system work efficiently and reduces the chance of cold air reaching vulnerable plumbing.
Inspect the attic, crawl space, basement, and exterior doors for:
- Damp or compressed insulation
- Drafts around windows and doors
- Gaps around plumbing and wiring penetrations
- Missing weatherstripping
- Damaged door sweeps
- Openings around vents
- Unsealed attic access panels
- Cold floors caused by crawl-space air leakage
Use exterior-rated caulk around appropriate window and trim gaps. Replace worn weatherstripping and install door sweeps where cold air enters beneath exterior doors.
Be careful around combustion appliances and crawl-space ventilation. Do not seal openings that are required for safe appliance operation or proper building ventilation.
If your home has a vented crawl space, ask a qualified professional whether additional insulation, air sealing, or moisture-control work is appropriate. Every home has a different construction design, so avoid covering vents or modifying insulation without understanding how the system is intended to operate.
6. Inspect the chimney and fireplace
If you plan to use a wood-burning fireplace or stove, schedule a professional inspection and cleaning before the first regular fire.
A chimney professional can check for:
- Creosote buildup
- Blockages
- Damaged flue liners
- Masonry deterioration
- Damaged flashing
- Problems with the chimney cap
- Proper damper operation
Clean the fireplace box and remove excess ash. Keep a properly rated fire extinguisher nearby, use a sturdy screen, and never leave a fire unattended.
Gas logs and other fuel-burning appliances also require appropriate inspection and ventilation. If you smell gas, leave the home and contact the utility provider or emergency services from a safe location.

7. Prepare before traveling or leaving for a PCS
If you are traveling during the winter or preparing for a PCS from Clarksville or Fort Campbell, do not leave winter protection to chance.
Before departure:
- Set the thermostat no lower than 55°F, consistent with local utility guidance.
- Ask a trusted person to check the home daily during freezing weather.
- Provide that person with the location of the main water shutoff valve.
- Leave contact information for your HVAC company, plumber, insurance agent, and property manager.
- Confirm smoke and carbon monoxide detectors are working.
- Disconnect outdoor hoses and protect exterior faucets.
- Consider whether your plumber recommends shutting off the home’s water supply while you are away.
- Keep cabinet doors open beneath vulnerable sinks during severe cold.
- Make sure gutters and downspouts are clear.
- Secure the garage, crawl-space access, and exterior doors.
If the property will be vacant during a military move, document its condition before leaving. Take photos of the water heater, HVAC system, utility meters, shutoff valves, and areas that have previously experienced leaks.
A vacant property can develop significant damage before anyone notices it. Daily checks are especially important after a hard freeze, winter storm, power outage, or extended period of below-freezing temperatures.

Frequently asked questions
What temperature should I leave my Clarksville home at during winter travel?
Set the thermostat no lower than 55°F when you are away, and arrange for someone to check the property daily during freezing weather.
Should I leave an outdoor faucet dripping?
A small trickle may help protect vulnerable interior plumbing during an extreme freeze, but it is not a substitute for disconnecting hoses, draining exterior lines, and insulating exposed pipes. Ask a licensed plumber if you are unsure about your home’s plumbing design.
Do I need to winterize a home in Clarksville every year?
Yes. Winter conditions vary, and a home that was protected last year may have a new leak, damaged faucet, aging insulation, or HVAC issue. A short annual inspection is less costly than discovering freeze damage after it occurs.
What should I do if I am selling my Clarksville home before winter?
Complete maintenance before listing photographs and showings. A pre-listing inspection, HVAC service, gutter cleaning, and professional staging can help you address concerns early and present the property with greater confidence.
