Cool mornings and shorter days are your cue that fall has arrived in Dallas. If you want fewer surprises when the first cold snap hits, a focused maintenance checklist can save you time, money, and stress. Whether you plan to stay put or list your home soon, a little prep now pays off all winter. This guide walks you through what to do and when to do it for our North Texas climate. Let’s dive in.
Know your Dallas fall timeline
Dallas usually sees its first freeze around late November, with the National Weather Service listing the average first 32°F day near November 22. Plan projects that depend on warm soil or dry weather several weeks before that date. Keep an eye on the forecast, since timing varies year to year. Check the NWS Fort Worth page for local freeze trends and updates to fine-tune your schedule. View average freeze dates and outlooks.
Roof and exterior essentials
Clean gutters and downspouts
Clear leaves and debris so water can flow away from your home. Clogged gutters can lead to roof leaks, fascia damage, and even ice buildup during rare cold spells. Consider gutter guards if trees overhang your roof. See when and how to clean gutters.
Inspect roof and flashing
Scan for missing shingles, cracked seals, and loose flashing around chimneys and vents. Small fixes now can prevent bigger leaks during winter rain and wind. If you notice cupping shingles or soft spots, schedule a professional inspection.
Seal windows, doors, and trim
Walk the exterior and touch up caulk where it has separated. Add weatherstripping to drafty doors to improve comfort and energy efficiency. A quick bead of sealant around penetrations can keep moisture out.
Check attic insulation and ventilation
Look for damp spots, uneven insulation, or blocked soffit vents. Balanced ventilation and adequate insulation help regulate temperature and reduce moisture issues. It also supports better heating performance inside.
Heating, fireplace, and safety
Schedule your HVAC tune-up
Book a heating check early in the season and replace filters per manufacturer guidance. Test your thermostat on heat mode and update batteries if needed. Routine maintenance boosts reliability and efficiency. Get ENERGY STAR’s seasonal HVAC tips.
Prep chimney or fireplace
Before the first fire, have a professional inspect and clean your chimney or gas logs. Creosote and blockages create fire risks, and an annual check helps catch issues early. Learn how often to clean a chimney.
Test smoke and CO alarms
Press the test button on each unit and replace batteries if needed. Replace smoke alarms that are past their service life, and install CO alarms near sleeping areas if you use gas appliances. For placement and replacement timing, review standards-based guidance. See code-aligned alarm recommendations.
Review gas safety basics
If you smell gas or suspect a leak, leave the area and contact your gas provider’s emergency number. Atmos Energy publishes emergency contacts and safety guidance for Dallas customers. Find Atmos Energy emergency contacts.
Water, pipes, and sprinklers
Protect pipes and faucets
Insulate exposed pipes in garages, attics, and exterior walls. Cover outdoor spigots and know how to locate and operate your private water shutoff valve. The City of Dallas shares winter weather steps for pipe protection and shutoff basics. Read the City of Dallas cold-weather guide.
Winterize your irrigation
Shut down or set controllers to minimal cycles as temperatures cool. Drain or blow out irrigation lines if your system requires it, and confirm freeze sensors work. If you are unsure about your setup, hire an irrigation pro. See how to winterize sprinklers in Texas.
Yard, trees, and pests
Trim trees and limbs
Remove dead or overhanging branches that could fall during wind or ice. Keep limbs clear of the roofline to reduce damage and debris. Hire a qualified arborist for work near power lines.
Lawn care and overseeding
Most Dallas lawns use warm-season grasses that go dormant in winter. Many homeowners overseed Bermuda with ryegrass for winter color in mid September through mid October, timed with soil temperatures. Plan aeration and a final fall fertilizer several weeks before the average first freeze. Get Dallas fall lawn care guidance.
Mosquito prevention
Fall can still bring mosquito activity during mild spells. Follow the local “4 Ds” approach: drain standing water, avoid dusk and dawn when possible, dress in long sleeves, and use repellent with DEET. Review Dallas mosquito control FAQs.
Keep pests out
Seal gaps larger than a quarter inch at the foundation, vents, and plumbing penetrations. Store firewood away from the house and keep screens and door sweeps in good repair. Reducing moisture and clutter helps deter termites and rodents.
A practical Dallas fall checklist
Early fall (September to mid October)
- Schedule your HVAC tune-up and change filters.
- Clean gutters once leaves start falling and check the roof.
- Aerate and overseed Bermuda if desired, and mulch beds.
- Book chimney inspection and cleaning.
Mid fall (late October to early November)
- Winterize irrigation or confirm freeze sensors work.
- Touch up caulking and add weatherstripping where needed.
- Reduce standing water and move firewood away from the house.
Pre-freeze (1 to 3 weeks before the first freeze)
- Insulate exposed pipes and cover exterior faucets.
- Locate and test your private water shutoff valve.
- Finish exterior painting or repairs ahead of winter weather.
During a freeze event
- Open cabinet doors for warm air flow to indoor plumbing.
- Let vulnerable faucets drip slightly.
- Avoid big thermostat setbacks that can stress your system.
- Follow local utility and city guidance for outages and safety.
