If you're a homeowner, you know that a house is like a living, breathing thing. It needs regular care and maintenance to stay in tip-top shape. One important but often overlooked task is watering your home's foundation. So, how often to water foundation?

The frequency of watering a foundation depends on factors like soil type, climate, weather patterns, and time of year, but as a general rule, aim to keep the soil moist 2-3 inches down by watering 1-3 times per week. Increase watering if experiencing drought or extreme heat or if you notice signs of foundation damage like cracks or sticking doors.

Properly hydrating the ground around and under your home's foundation is essential to prevent cracking and shifting. But how often should you be doing this important chore? We're here to tell you!

Why Watering Your Foundation Matters

Your home's foundation bears the entire weight of your house. It must remain stable so your home stays structurally sound. The soil underneath your foundation needs to stay compacted but not overly dry. Excessive moisture can damage a foundation, but so can overly dry soil.

When soil dries out too much, it contracts and shrinks, creating gaps under the foundation. This allows the foundation to shift and crack under the home's weight. Watering helps keep the soil hydrated and expanded to provide solid support. Think of it like giving the soil a drink to keep it in prime condition!

How Often to Water Foundation? 

Many factors determine how often your foundation needs watering. The soil type, climate, weather patterns, landscaping, and time of year all play a role. Here are some general guidelines on frequency:

  • Clay soil foundations: Water 1-2 times per week
  • Sandy or gravelly soil foundations: Water 2-3 times per week
  • Extreme weather: Increase watering frequency if experiencing drought or excess heat
  • Dry climates: Water more frequently than humid climates
  • Spring and summer: Water more frequently than fall and winter

A good rule of thumb is to check the soil around your foundation weekly by digging down a few inches with a trowel. If it's dry 2-3 inches down, it's time to water. Aim to keep the soil moist but not saturated.

Watering Tips

When watering your foundation, follow these tips:

  • Use a soaker hose or sprinkler, not a handheld hose. This distributes water evenly.
  • Run water slowly to prevent runoff. Let it fully soak into the ground.
  • Water at least 5 feet out from the foundation perimeter. Focus on corners and other vulnerable areas.
  • Water in the early morning or evening to reduce evaporation. Avoid midday watering.
  • Inspect sprinkler coverage and adjust areas missing foundation coverage.
  • In winter, water on sunny days when temperatures are above freezing.
  • Don't overwater! Saturated soil can cause foundation damage, too.

Signs Your Foundation Needs Water

How can you tell when your foundation desperately needs some hydration? Look for these signs:

  • Cracks in exterior walls or inside sheetrock.
  • Doors or windows sticking or not closing properly.
  • Separation between brickwork.
  • Floor or tile cracking inside home.
  • Damaged outbuildings like sheds shifting.
  • Areas of sinking or uneven ground around foundation.

If you spot these issues, increase your foundation watering frequency. Catching soil moisture issues early prevents more serious foundation damage.

Consider Professional Watering Systems

Manually watering your foundation weekly or more takes diligence. Many homeowners opt to install professional foundation watering systems. These use automated timers, pipes, and sprinklers to handle the watering schedule for you.

Foundation watering systems are relatively affordable DIY projects. But, you may wish to hire an irrigation specialist for installation and to tailor the system to your landscape. This guarantees proper coverage and frees you from remembering to water. Look for systems with smart technology that adjust based on weather.

Adequately hydrating the soil surrounding your home's foundation is critical maintenance. Make watering the ground around your house's perimeter as routine as mowing the lawn.

Should I water my house foundation to keep it from cracking?

Yes, you should periodically water your home's foundation to keep the surrounding soil hydrated and prevent cracking. Soil that dries out excessively can shrink and contract, allowing the foundation to shift and develop cracks under the weight of the house. Aim to keep the soil near the foundation perimeter moist 2-3 inches down by watering 1-3 times per week, depending on climate, soil type, and weather patterns. Watering the ground around your foundation's perimeter will help stabilize the soil and reduce the chances of foundation cracks developing.

How often should I water my foundation during a drought?

During a drought, you should increase the frequency of watering your foundation to 2-3 times per week minimum to keep the soil moisture stable, as dry soil causes foundations to shift and crack without adequate hydration. Monitor soil moisture levels around the entire perimeter of your foundation by digging down a few inches, and water any areas that feel dry or powdery to a depth of several inches to prevent damage from parched soil.

How often do you use a soaker hose for foundation?

A soaker hose is an efficient and effective way to hydrate the soil around your home's foundation. These hoses slowly seep water into the ground, preventing runoff and evenly distributing moisture. For most foundations, running a soaker hose for 30-60 minutes 1-3 times per week is sufficient. Focus on keeping the soil moist 2-3 inches down around the entire perimeter of the foundation, moving the soaker hose as needed to hit all areas. Using a timer with your soaker hose makes watering the foundation perimeter an easy, hassle-free routine.

When should I stop watering my foundation?

You should stop watering your foundation when the soil around the perimeter is adequately hydrated. Check moisture levels by digging down a few inches in multiple spots and stopping watering when the soil feels damp 2-3 inches below the surface. Be careful not to oversaturate the soil, as overly wet conditions can damage foundations as well. In most climates, watering 1-3 times per week is sufficient for foundation health. You may be able to reduce watering frequency in cooler months when evaporation is slower. If rains have recently soaked the ground around your home's foundation, hold off on additional watering until the soil dries out again. Stop manual watering if you have an automated irrigation system handling the foundation perimeter hydration for you. The key is maintaining soil moisture, not oversaturating, around the entire foundation.
