When temperatures drop to 28°F or below in the Dallas-Fort Worth Metroplex, unprepared homes face serious risks: burst pipes, water damage, and costly emergency repairs. Unlike northern climates, DFW homes, from Southlake to Arlington, Frisco to Mansfield, aren't always built for prolonged freezes, making winterization critical during North Texas cold snaps.
This comprehensive checklist covers everything DFW homeowners need to know to protect their investment when the mercury plummets.
Why Winterizing Your DFW Home Is Non-Negotiable
North Texas winters are unpredictable, 80°F one day, 20°F the next. When hard freezes hit neighborhoods across Colleyville, Keller, Grapevine, and Bedford, water inside pipes and irrigation systems expands by 9%, causing:
- ✗ Burst pipes and flooding
- ✗ Irrigation system damage (especially RPZ and DCA backflow devices)
- ✗ $5,000+ in emergency repairs
- ✗ Prolonged water service disruptions
Quick action saves thousands. Here's your room-by-room winterization plan.
1. Set Your Thermostat to Prevent Frozen Pipes (Critical First Step)
Occupied Homes:
- Minimum setting: 65°F (never lower, even when sleeping)
- Maintain consistent temperature 24/7, don't let it dip at night
- For homes in older DFW neighborhoods (Oak Cliff, Ridglea, Historic Downtown Fort Worth), consider 68°F minimum
Vacant or Vacation Properties:
- Never set below 55°F, this is the minimum freeze protection threshold
- If leaving for extended periods (snowbird season), consider shutting off main water supply
- Ask a neighbor in Southlake, Westlake, or Trophy Club to check your home during freeze warnings
During Active Freeze Warnings (Below 28°F):
- Drip all faucets on exterior walls (both hot and cold), a pencil-lead thin stream is sufficient
- Open cabinet doors under kitchen and bathroom sinks to allow warm air circulation
- Keep garage doors closed if plumbing runs through garage (common in DFW homes)
Pro Tip: Locate your main water shut-off valve now, don't wait until pipes burst. In most DFW homes, it's in the garage, utility room, or near the water heater.
2. Protect Exterior Plumbing & Water Lines (High-Risk Freeze Zones)
Plumbing along exterior walls, in attics, and in unheated garages is most vulnerable during DFW hard freezes.
Outdoor Faucet Protection:
- Disconnect and drain all garden hoses (standing water will freeze inside)
- Install insulated faucet covers on all outdoor spigots (available at Home Depot, Lowe's)
- Check for dripping faucets, replace worn washers now before they freeze and crack
Exposed Pipe Insulation:
- Wrap exposed pipes in attics, crawl spaces, and garages with foam pipe insulation
- Pay special attention to homes built before 2000 in Hurst, Euless, and North Richland Hills
- Use heat tape for pipes in unheated areas (follow manufacturer instructions carefully)
Laundry & Utility Rooms:
- Avoid running washing machines or dishwashers overnight during hard freezes
- Keep laundry room doors open if located in garage or along exterior walls
3. Winterize Irrigation Systems & Backflow Devices (Often Overlooked, Costly Damage)
This is where most DFW homeowners lose money. Irrigation systems and backflow prevention devices (required by Fort Worth, Southlake, and Colleyville) are highly susceptible to freeze damage.
Before Temperatures Hit 28°F:
Step 1: Turn OFF Irrigation Controller
- Locate your irrigation timer (usually in garage or exterior wall)
- Switch to "OFF" or "Rain Mode", do NOT rely on automatic scheduling
Step 2: Drain the System Completely
- Open all valves: Double Check Valves (DCA), Reduced Pressure Zone (RPZ) devices, and irrigation zone valves
- Allow all standing water to drain, trapped water will freeze and crack backflow assemblies
- Test cocks and drain ports on RPZ/DCA devices must be fully open
Step 3: Protect Backflow Devices
- Cover exposed RPZ and DCA devices with insulated backflow covers or wrapped blankets
- Never use plastic bags, condensation causes more damage
Need Visual Instructions?
Many DFW cities provide step-by-step guides:
4. Seal Doors, Windows & Draft Points (Energy Savings + Freeze Protection)
Cold air infiltration makes your HVAC work harder and exposes pipes to freezing temps.
Door & Window Weatherproofing:
- Install new door sweeps and weatherstripping on all exterior doors
- DIY Draft Stopper: Roll an old beach towel and place at door base (free and effective!)
- Apply window film or plastic sheeting to single-pane windows (common in older DFW homes)
- Close blinds and curtains at night to retain heat
Check Attic & Garage Insulation:
- Inspect attic insulation, R-30 minimum recommended for North Texas
- Seal gaps around attic access points where warm air escapes
- Keep garage doors closed during freezes (protects garage-located water heaters and pipes)
5. HVAC System Preparation (Don't Get Caught in a Cold Snap)
Your heating system is your first defense against frozen pipes and a comfortable home.
Pre-Winter HVAC Checklist:
- Schedule professional inspection before first freeze (call Enoch at 817-769-3712)
- Change air filters monthly during winter (dirty filters reduce efficiency by 15%)
- Test your heater now, don't wait until you need it
- Small burning smell for 2-3 minutes is normal (dust burn-off)
- If smell persists longer than 5 minutes or you notice odd noises, call immediately
- Ensure air vents are not blocked by furniture or curtains
Ceiling Fan Trick:
- Reverse fan direction to clockwise (most fans have a switch on motor housing)
- Run on low speed to push warm air down from ceiling
- This simple step saves 10% on heating costs in vaulted ceiling homes (common in Keller, Colleyville)
6. Fireplace & Chimney Safety (Essential for Wood-Burning Homes)
Many DFW homes in Trophy Club, Westlake, and Highland Village feature fireplaces, ensure safe operation.
Before First Use:
- Hire a certified chimney sweep to remove creosote buildup and debris
- Inspect for cracks in mortar, bricks, and flue liner
- Test the damper, ensure it opens/closes fully
- Check for animal nests (common in unused chimneys)
During Use:
- Never leave fires unattended
- Use a fireplace screen to prevent ember escape
- Dispose of ashes in metal container (ashes stay hot for days)
7. Carbon Monoxide & Smoke Detector Testing (Life-Saving Step)
Winter heating increases carbon monoxide risks, especially in homes with gas furnaces (common across DFW).
Detector Checklist:
- Test all smoke alarms monthly (press test button)
- Replace batteries annually, do it when you change clocks for daylight saving time
- Upgrade to combination CO/smoke detectors with digital displays
- Replace detectors older than 10 years
Homes in Plano, Carrollton, and Flower Mound with natural gas heating should prioritize CO detector placement near bedrooms.
8. Exterior Home & Landscape Protection
Gutters & Downspouts:
- Clean gutters of fall leaves before first freeze
- Flush with water to ensure proper drainage
- Inspect for leaks and loose fasteners
- Ensure downspouts direct water 6+ feet from foundation (prevents ice dams and foundation damage)
Roof Inspection:
- Check for missing or damaged shingles
- Trim tree limbs that overhang roof (ice buildup causes branch breaks)
- Remove dead or damaged limbs that could fall during ice storms
Protect Plants & Landscaping:
- Move potted plants into garage or covered patio
- Cover delicate plants with frost cloth or burlap (not plastic!)
- Water plants before freeze, moist soil retains heat better than dry soil
- Mulch around plant bases for insulation
9. Pest Prevention (Cold Weather Invites Unwanted Guests)
When temperatures drop in Arlington, Grand Prairie, and Irving, rodents and pests seek warmth inside your home.
Seal Entry Points:
- Inspect foundation, windows, and doors for cracks/gaps
- Apply caulk or weatherstripping to seal openings
- Check utility line entry points (HVAC, plumbing, electrical)
- Install door sweeps on garage doors
Remove Attractants:
- Store food in airtight containers
- Take out trash regularly
- Don't leave pet food out overnight
Older homes in Oak Cliff, Fairmount, and historic neighborhoods are especially prone to pest infiltration.
10. Water Heater Maintenance (Improve Efficiency Before Heavy Use)
Winter is hard on water heaters, prepare yours for increased demand.
Annual Flush:
- Drain sediment from tank bottom (reduces efficiency and lifespan)
- YouTube tutorials available or call Enoch at 817-769-3712 for service
- Inspect temperature/pressure relief valve, ensure it's not dripping
- Set temperature to 120°F (prevents scalding and saves energy)
Insulate Older Units:
- Wrap water heater in insulation blanket if located in unheated garage
- Insulate first 6 feet of hot water pipes leaving tank
11. Emergency Preparedness (Be Ready for Extended Freezes)
Remember the 2021 Texas freeze? DFW lost power and water for days. Be prepared.
Emergency Supplies:
- ✓ Flashlights & batteries (LED flashlights last longer)
- ✓ Bottled water (1 gallon per person per day for 3 days)
- ✓ Non-perishable food
- ✓ Battery-powered or hand-crank radio
- ✓ First aid kit
- ✓ Blankets & warm clothing
- ✓ Cell phone power banks
Never Do This:
- ✗ Never use ovens, grills, or generators indoors to heat your home (carbon monoxide poisoning)
- ✗ Never operate generators in garages (even with door open)
- ✗ Never completely shut off water if heat is turned off
- ✗ Never use space heaters unattended or near flammable materials
Final Thoughts: Stay Warm, Stay Safe, Stay Protected
Texas winters may be unpredictable, but your preparation doesn't have to be. By following this comprehensive DFW winterization guide, you'll protect your home, save money on emergency repairs, and enjoy peace of mind when the next hard freeze hits.
