Moving to North Texas: What Is Different About the House
Plenty of people arrive here having owned houses for decades and find that most of what they knew does not transfer.

A large share of the people we work for did not grow up here. They moved to Rockwall, Wylie, Forney, Princeton or McKinney in the last few years, often from somewhere with basements, and they arrive with a working mental model of a house that does not quite apply.
None of this is bad news. It is just different, and knowing the differences early avoids a set of predictable and expensive surprises.
There is no basement, and the plumbing is in the concrete
Almost every house here is built on a concrete slab poured directly on the ground, with the drain lines cast into or run beneath it. That single fact drives most of the rest.
You cannot go downstairs and look at a pipe. A leak under the slab does not drip into a basement where you find it — it goes into the ground, and you find it from a warm spot on the floor, an unexplained water bill, or the sound of running water with everything off. Slab leak detection is a specialist activity here in a way it is not elsewhere.
The soil moves, and it moves a lot
North Texas clay is expansive. It swells when wet and shrinks when dry, and the difference between a wet spring and a dry August is enough movement to crack drywall, stick doors and stress the plumbing cast into the slab.
This is why foundation watering is a real practice here and not folklore. Keeping soil moisture around the perimeter reasonably consistent through a dry summer reduces differential movement. Soaker hoses set back a foot or so from the foundation, run modestly and regularly, are the standard approach — and most cities allow it even under watering restrictions for exactly this reason.
The mechanical equipment lives in the attic
With no basement, the air handler and frequently the water heater go into the attic. In July that attic is 140°F, and it is above your ceiling.
- Ductwork runs through that heat, so leaks and poor insulation cost far more here than in a climate where duct runs through conditioned space.
- A water heater in the attic needs a pan, a working pan drain and a correctly routed relief discharge. Check all three now rather than after.
- The condensate drain line is doing serious work all summer. A blockage backs up into the pan and, if the overflow switch is missing or failed, into your ceiling.
- Equipment in a 140° space simply ages faster than equipment in a basement.
The cooling season is long and the heating season is short but vicious
Air conditioning runs from roughly April to October, sometimes longer, and it runs hard. Annual maintenance is not a formality here — a coil that is fouled or a system that is low on charge will fail in August, not in a mild month, and August is when everybody else is failing too.
Heating is a smaller load, but the region gets occasional hard freezes that are genuinely severe, and the housing stock is not built for them the way northern housing is. Uninsulated attic pipe runs, exposed hose bibs and slab-edge plumbing all become vulnerable. The precautions matter more here than the mild winter average suggests.
The water is harder than you are used to, probably
Moderately hard on most municipal supply, and considerably harder on many private wells outside the cities. Water heaters scale, fixtures fur up, and annual flushing goes from optional to genuinely worthwhile.
A short list for your first year
- Find your main water shutoff and confirm the valve turns. Do this before you need it.
- Check house pressure at a hose bib with a gauge. Over 80 psi means the pressure reducing valve needs attention.
- Read the date off the water heater and note where it sits — attic, closet, garage.
- Look at the attic condensate line and its safety switch.
- Get the HVAC serviced before the first hot week, not during it.
- Set up foundation watering before the first dry spell rather than after the first crack.
- Insulate exposed hose bibs and any attic plumbing before the first freeze.

Frequently asked
Why do I need to water my foundation?
Because the clay soil here shrinks when it dries, and uneven shrinkage under a slab causes differential movement — which cracks walls, sticks doors and stresses the plumbing cast into the concrete. Keeping perimeter soil moisture reasonably consistent through a dry summer is cheaper than the alternative by a very wide margin.
How do I know if I have a slab leak?
The common signs are a warm spot on the floor, the sound of running water with everything off, an unexplained rise in the water bill, or unexplained damp in flooring. Confirming it means isolating the house and watching the meter, then locating it acoustically — you cannot simply go and look, which is the main practical difference from a house with a basement.
Is annual HVAC maintenance really necessary in Texas?
More so than in a milder climate. The cooling season here runs six months or more at high load, and the failures that maintenance catches — a fouled coil, a weak capacitor, a marginal charge — are the ones that turn into a breakdown in August when every company in the county is booked.
