The family behind the J
Three generations of John. One family name on every well.
Triangle J was founded in 2021 by John Scott Gandy and John Dawson Gandy. The "J" stands for the generations of John who came before us, and the ones we hope carry it forward.
We answer the phone ourselves. We show up when we say we will. And we treat every job like the family name is on it, because it is.
Sited on data, not luck
We check the well records before we ever spud in
Before drilling, we study state well records around your property: how deep the water has been historically, what formations we'll drill through, and which aquifer your neighbors produce from. Then we design the well construction to match.
In our home counties that usually means the Trinity or Woodbine aquifer. Here's how the two compare, and what that means for your well's depth and cost.

The questions we hear most
How much does it cost to drill a well in North Texas?
Most complete residential systems here run between $11,000 and $60,000+, depending on depth, geology, and the pump and storage equipment your property needs. See the full 2026 cost guide.
How long does the whole process take?
Permitting typically takes 2-4 weeks in most North Texas counties, and we handle most of that paperwork. Drilling itself usually takes days, not weeks. Full timeline here.
Do you handle the permits?
In most cases, yes. We coordinate and handle the permits required for drilling, working with your groundwater district directly. If a county requires an engineered site plan, obtaining that stays with the property owner.
Is your work under warranty?
Yes. Every newly drilled well we complete is covered by a 2-year warranty, and we're licensed (TX #61646) and insured.
