The town began as Duncan Switch when the railroad arrived in 1880, took the name Duncanville two years later, and incorporated in 1947. Growth took off after World War II, when an Army Air Corps field and later an Air Force station brought people to southwestern Dallas County. The population jumped from 3,774 in 1960 to 14,105 in 1970 and kept climbing; the 2020 census counted 40,706 residents and about 14,200 homes.

Southwest Dallas County weather and property hazards
The city sits at roughly 715 feet, with Interstate 20 crossing its north side and U.S. 67 running along the east. Spring and early summer bring the typical North Texas mix of hail, straight-line wind, tornadoes and sudden downpours, while summer heat keeps air conditioning running for months.
Dallas County has been named in seven major disaster declarations since 2000, including Hurricane Rita (2005), the Extreme Wildfire Threat (2006), storms and flooding in 2015 and 2016, Hurricane Harvey (2017), the 2021 Severe Winter Storms and the 2024 storms, tornadoes and flooding. In February 2021, DFW Airport spent 139 consecutive hours at or below freezing and bottomed out at -2°F.
Half-century-old plumbing and other leak sources
Homes from the 1960s and 1970s often still have original drain lines, aging shut-off valves and water heaters that have been replaced several times in the same closet, sometimes without updated drain pans. Slab leaks beneath the foundation are another concern as pipes age, along with roof leaks after hail and frozen lines during long cold snaps like 2021.
Water damage restoration in Duncanville usually begins with finding and stopping the leak, followed by water extraction, moisture testing in walls, cabinets and flooring, and several days of drying with fans and dehumidifiers. The pages on emergency water removal and water damage restoration cover each stage.

Handling smoke and fire damage in established neighborhoods
Older electrical systems, space heaters during freezes and kitchen fires are frequent ignition sources in mature housing. Smoke and soot reach well beyond the burned room, clinging to textured ceilings, cabinets and HVAC returns.
A reputable restoration company will usually stabilize the structure, remove debris, test which surfaces can be cleaned, and then wash, seal or replace materials before deodorizing. If you need more, our fire damage cleanup page and the smoke odor removal guide go further.
Storm and flood cleanup after North Texas downpours
Intense spring rain can flood streets and push water into garages and low rooms, and hail can crack aging roof shingles that were already near replacement. The county's 2015, 2016 and 2024 declarations each listed flooding along with tornadoes or straight-line winds.
After storms, contractors commonly tarp roofs, remove fallen limbs from the structure, extract water and cut away wet drywall and insulation that outside water reached. Learn more under storm water damage restoration and flood cleanup.
Spotting and stopping mold
Slow leaks in older bathrooms and kitchens, combined with humid summers, are a recipe for hidden mold. Watch for musty smells, soft drywall around tubs, and stains on ceilings below the attic air handler.
Following EPA guidance, a homeowner can generally clean an area under about 10 square feet after fixing the moisture problem. For anything larger, growth in ductwork, or mold after sewage backup, look into professional mold remediation.
Safety guidance for Duncanville residents
- Call 911 for any fire, injury, gas odor or fallen power line.
- Close the main water valve, and keep away from wet electrical outlets and sagging ceilings.
- Get county alert and preparedness information from Dallas County Homeland Security and Emergency Management.
- Monitor National Weather Service Fort Worth warnings during storms and freezes.
- Document damage with photos and video and keep receipts.
- Ask your insurer or agent which damage your policy includes; coverage varies.

Duncanville restoration FAQs
Why do so many Duncanville homes have plumbing issues?
The city's population grew nearly sevenfold between 1960 and 1980, so many homes are roughly 45 to 60 years old. Original drain lines, valves and supply pipes in houses that age are more likely to fail.
How long did the 2021 freeze last around here?
The National Weather Service recorded 139 straight hours at or below freezing at DFW Airport, from February 13 to 19, 2021. That stretch caused frozen and burst pipes across the region.
Do contractors from Cedar Hill or DeSoto work in Duncanville?
Often, yes. Cedar Hill and DeSoto are each about five miles away, and restoration firms commonly set service areas that span several neighboring suburbs. Ask any contractor to confirm your address is within their area.
Can Fire & Water Energy deal with my insurer for me?
No. We are a referral service only and do not deal with insurers. Coverage depends on your policy, so speak with your agent; we can try to connect you with an independent contractor at (866) 937-3230.
