How it benefits you:
If you smell gas, leave the house right away and call 911. For a burst pipe or major leak, shut off your main water valve first, then call us at (903) 449-1677 for a fast response. While you wait, try to mop up water to protect your floors, or if it’s winter, turn the heat up and increase airflow to protect against pipe freezes. We offer same-day emergency service throughout Texoma and DFW.
Because of our expansive clay soil, Dallas–Fort Worth homes built on slab foundations with copper pipes are especially prone to slab leaks. The most common warning signs are the sound of running water when all your faucets are off, warm spots on the floor, or an unexplained jump in your water bill. You might also notice a lingering moldy smell, damp flooring, or cracks in your walls. There is no need to jackhammer your floors for a diagnosis, because we use electronic and thermal imaging to pinpoint these leaks.
Clogging, bad odors, and slow drains throughout areas of the house are signs that replacement is worth considering. Cast iron pipes typically last 50 to 75 years, so if your home was built before 1980, yours are probably nearing the end of their lifespan. Shifting clay soil in Texoma and the DFW Metroplex causes cast iron to crack and fail sooner than it does in other regions. We replace these failing legacy systems with Schedule 40 PVC, which is designed to last 75 to 100 years.
Yes. Depending on your city, water in our service area measures anywhere from 140 to more than 210 ppm, which is classified as hard to very hard. The mineral scale it leaves behind can shorten the lifespan of a water heater by years. A whole-home water softener can save DFW homeowners more than $1,500 a year in energy, soap, and appliance repair costs.
