At PuroClean of Lawrenceville, we’ve helped hundreds of families recover from flooding disasters. Here’s what we’ve learned about the most common causes of flooding in our area—and what you can do to prevent them.
1. Heavy Rain and Flash Flooding
Lawrenceville is no stranger to intense rainfall, especially during Georgia’s storm season. When the ground becomes oversaturated, or storm drains are overwhelmed, water can quickly back up and flood yards, crawl spaces, and even basements.
Prevention Tip:
- Install a sump pump with a battery backup.
- Make sure your yard slopes away from your home.
- Keep storm drains and gutters clean and debris-free.
2. Clogged or Broken Gutters
Gutters are your home’s first defense against water intrusion. But when they’re clogged with leaves or debris, water can spill over and seep into your foundation, walls, or basement.
Prevention Tip:
- Clean gutters at least twice a year.
- Extend downspouts at least 5–10 feet away from your home.
- Consider gutter guards to reduce buildup.
3. Foundation Cracks
Small foundation cracks may seem harmless, but during a storm, they can let in gallons of water. These leaks are common in older homes and properties located in low-lying areas.
Prevention Tip:
- Inspect your foundation regularly for cracks or signs of water.
- Seal small cracks with waterproof masonry sealant.
- Contact a foundation repair specialist if you notice shifting or large gaps.
4. Failed Sump Pumps
A sump pump is designed to remove water from your basement or crawl space. If it fails during a storm—especially if the power goes out—your home can flood quickly.
Prevention Tip:
- Test your sump pump monthly.
- Install a battery or water-powered backup pump.
- Consider an alarm that alerts you when your sump pump fails.
5. Plumbing Failures
Burst pipes, worn-out hoses, and old water heaters are all common causes of residential flooding. In Lawrenceville, temperature drops during winter can also lead to frozen pipes that eventually burst.
Prevention Tip:
- Replace rubber hoses with braided steel ones.
- Insulate exposed pipes.
- Schedule annual plumbing inspections.
6. Sewage Backups
Sewage backups not only cause water damage but also present serious health hazards. These usually occur when sewer lines become clogged or overwhelmed during storms.
Prevention Tip:
- Don’t pour grease or non-flushable items down your drains.
- Install a backwater valve to prevent sewer water from entering your home.
- Contact your local utility if you experience frequent backups.
7. Poor Landscape Grading
When your yard or property slopes toward your home instead of away from it, you’re inviting water to pool around your foundation during every heavy rain. Over time, this runoff can seep into basements, crawl spaces, or slab foundations, weakening the structure and increasing the risk of residential flooding. Poor grading is especially common in older neighborhoods or after DIY landscaping projects that unintentionally disrupt natural drainage.
Prevention Tip:
- Re-grade your yard to ensure that the soil slopes away from your foundation by at least 6 inches over 10 feet.
- Incorporate French drains or swales to redirect excess water.
- Add gravel beds or rain gardens in problem areas to slow and absorb runoff.
- Consult a landscaping or drainage specialist to assess your property and recommend solutions tailored to your home and soil type.
Prevention Tip:
Use gravel and drain tile to redirect water runoff.
Re-grade your yard to create a slope away from your home.
