How to Fix and Prevent Water Intrusion in Your Home with Rainstorms Ahead

With rainstorms just around the corner, now is the time to make sure your home is equipped to handle whatever weather comes your way. Water intrusion—whether it’s from leaky windows, cracked foundations, or damaged roofs—can lead to costly repairs if left unaddressed. Here’s how to fix existing water intrusion issues and prevent new ones to keep your home safe and dry.

1. Check and Seal Windows and Doors

Windows and doors are prime entry points for water. Check for any gaps or cracks around the frames where water could seep through. Pay particular attention to areas where caulking is cracked or worn out. If you spot any gaps, apply fresh, waterproof caulk to seal them. For a more secure fix, consider installing weather stripping around doors and windows. Not only will this keep water out, but it’ll also make your home more energy-efficient by keeping warm air in.

2. Inspect and Clean Gutters and Downspouts

Gutters and downspouts are your home’s first line of defense against water intrusion. Blocked gutters can lead to water overflowing onto your roof and walls, which can then seep into your home’s foundation or basement. Make sure your gutters are clear of leaves and debris, and that downspouts are directing water at least five feet away from your home’s foundation. For extra protection, consider installing gutter guards to keep debris out and improve water flow.

3. Repair Roof Damage

Your roof is constantly exposed to the elements, so it’s essential to check for damaged or missing shingles, especially before heavy rain. Damaged shingles can allow water to penetrate into your attic and cause leaks. If you see any loose or cracked shingles, replace them as soon as possible. Additionally, check flashing around chimneys, vents, and skylights for any signs of damage or lifting. Flashing seals are often the source of leaks and are easy to repair or replace.

4. Address Foundation Cracks

Water can easily make its way into your basement or crawl space through small cracks in your foundation. Inspect your foundation walls for any visible cracks, no matter how small. For minor cracks, you can use a masonry sealant to fill them. Larger cracks may require a professional evaluation to determine if structural repair is necessary. After sealing any cracks, consider installing a French drain or sump pump in areas with a history of flooding for added protection.

5. Assess Exterior Siding and Paint

Cracks or gaps in your home’s siding or paint can also lead to water intrusion. Walk around your home and inspect exterior walls for any peeling paint, loose siding, or cracks. Touch up areas where paint has worn away and consider adding a waterproof sealant to help your siding withstand rain. If you have wooden siding, check for signs of rot, as these areas will be especially vulnerable to water damage.

6. Install or Test a Sump Pump

If you have a basement, a sump pump is a crucial piece of equipment to prevent water from pooling in your home. If you already have one, test it to make sure it’s working correctly. If you don’t have one, consider installing one before the rain hits. A sump pump works by collecting water that enters your basement and pumping it outside before it can cause damage.

7. Grade Your Yard

One often-overlooked cause of water intrusion is improper yard grading. If your yard slopes towards your home, rainwater will naturally flow toward your foundation, increasing the risk of water seeping inside. Regrading your yard so it slopes away from your home can direct water away, helping to protect your foundation. This is especially important if you have flower beds or landscaping near your home that might trap water.

Final Thoughts

Water intrusion is not just an inconvenience—it can lead to mold, structural damage, and expensive repairs if not addressed. A few proactive steps can make all the difference, keeping your home safe from rain-related issues. Take a weekend to make these checks, and rest easy knowing that when the storm hits, your home is ready to weather it.
