Should You Water Your Foundation During a Texas Summer?

The short answer is yes — and it's one of the most important things you can do to protect your foundation during a Texas summer. Here's the science behind it and how to do it right.

Why Watering Helps

Frisco's expansive clay soil shrinks as it dries out during the summer. When the soil shrinks, it pulls away from your foundation, creating voids. The slab is no longer fully supported, which can cause it to crack or settle. By keeping the soil consistently moist, you prevent excessive shrinkage and maintain uniform support for your foundation.

How to Water Your Foundation

Use a soaker hose placed 12–18 inches from the foundation wall. Run it for 15–20 minutes per section, 2–3 times per week during dry spells. The goal is to keep the soil moist, not saturated. Water all sides of the foundation evenly — uneven moisture can cause differential movement. Many Frisco homeowners install automatic foundation watering systems with timers for convenience.

What Not to Do

Don't overwater — saturated soil can cause its own problems. Don't water right against the foundation — keep the hose 12–18 inches away. Don't water during a rain event. And don't stop watering when the temperature drops — the key is maintaining consistent moisture, not reacting to weather.

Other Summer Tips

Keep gutters clean and downspouts extended. Check grading to ensure water flows away from the foundation. And if you notice new cracks or sticking doors during a dry spell, it could be a sign that your foundation is moving. Schedule an inspection to be safe.
