How to Prevent Water Damage

Proper downspout drainage for a house

Key Takeaways

Water damage is the No. 1 culprit that weakens your home’s foundation and the very core that holds your house together.

You’ve heard about core strength for your body. Well, water damage hits at the core strength of your house, eventually causing serious structural damage. Damp wood invites termites and carpenter ants and causes mold and mildew.

Here’s are three easy strategies to prevent water damage and have peace of mind the next time heavy storms hit.

#1. Ensure Good Drainage

Why it matters: Poor drainage weakens your foundation, causing cracks, uneven settling, and pathways for water to enter your home.

How to do it:

Maintenance cost: Very little. Cleaning gutters can be a no-cost DIY job or you can hire a pro for $50 to $250, depending on the size and height of your home. To get the soil slope you need, you might have to buy additional topsoil.

Worst case if you put it off: Your foundation could settle, cracking your basement walls. The cost to stabilize, repair, and seal deteriorated foundation walls is a whopping $15,000 to $40,000.

#2. Test Your Sump Pump Regularly

Why it matters: Sump pumps come to life during storms. That’s not when you want to realize yours isn’t working properly. You should check it at least once a year and ideally perform several checks during heavy storm seasons.

How to test your sump pump:

  1. Slowly fill the sump pump pit with water. Watch for the “float” (similar to the float in your toilet) to rise, which should turn on the pump. Then watch to make sure the water level falls.
  2. Test your backup pump the same way, but unplug the main pump first.
  3. If you don’t have a backup pump — or a generator — and are on municipal water, get a backup pump that runs on water pressure. If you’re on well water, your only option is the battery kind.

Maintenance cost: Testing is free; a water-powered backup sump pump, including installation, costs $150 to $350; a new battery for a battery-operated sump starts around $200.

Worst case if you put it off: Your basement could flood, ruining everything in it, including drywall and carpeting. (Did you know your regular insurance doesn’t cover flooding?) Plus you run the risk of mold and mildew — which can also be a very expensive problem.

#3. Check for Water Leaks and Fix Them

Why it matters: Persistent leaks lead to mold and mildew, rot, and even termites and carpenter ants (they like chewing soggy wood, since it’s soft). But if you fix a leak soon after it starts, there may be no long-term damage at all.

Maintenance cost: Negligible for a simple fix, such as a new washer. A visit from a plumber might set you back $250; a roof repair, a few hundred dollars to $1,000.

Worst case if you put it off: Drips ruin the cabinet under the kitchen sink, and run down into the floor sheathing and joists underneath, so you need a structural repair, plus new cabinets and new kitchen flooring. Or the roof rots, so you need a new roof and repairs to rooms directly beneath.

So now you know how to prevent water damage — and add years and lower maintenance costs to your home!
