What are common basement waterproofing issues?
While the first symptom of a basement waterproofing problem is usually standing water, a musty smell, or mold growth — and the root cause of a leak can vary. A flooded basement or water damage can result from leaky basement walls, foundation wall cracks, damaged drain systems, and more. If you notice any of these issues in your basement, be sure to contact LeBlanc for all of your basement flooding prevention needs.
Can you seal basement walls from the inside?
Yes, you can! In fact, sealing basement walls from the inside is something we excel at. Our interior basement waterproofing services include a variety of solutions — from sump pumps to vapor barriers. Vapor barriers stop any moisture and water that seeps through your concrete foundation walls. This keeps your basement dry, livable, and protected from flooding.
Should I waterproof my basement from the inside or outside?

The best basement waterproofing method depends on what is causing the leaks. Our experts can walk you through the details of what each method would look like for your home.

Waterproofing your basement from the inside is typically less disruptive than exterior waterproofing solutions and more cost-effective. This waterproofing technique prevents water from reaching your foundation walls and prevents moisture from seeping in.

Waterproofing your basement or home from the outside is a proactive solution to preventing water from getting inside your home. Exterior waterproofing involves sealing and protecting exterior walls, installing drains, and leading water away from your home's foundation walls. This keeps water out before it can come into your basement.

No matter what your choose, our experts here at LeBlanc Basement Waterproofing will help you make the best choice for your home and budget!

What kind of maintenance is required for a sump pump?
We use regular flood testing to ensure that your sump pump works correctly. Doing this annually (and preferably before the "wet" season) ensures that it will be functioning effectively when you need it. Sump pumps also can have an alarm system to notify you if a function isn’t operating correctly.
How long does it take to waterproof the basement or crawl space?
Depending on the issue, repairs and waterproofing can take anywhere from a few hours to a couple of weeks. When you contact us for a free estimate, we offer specific timelines for your project.
How can I prevent mold growth in my basement?

A sump pump is a great way to prevent mold growth in your basement. A sump pump pumps water out of your basement and away from your home, typically to a storm drain or well. This prevents your basement from experiencing high moisture levels where mold thrives.

Sump pumps are also great at protecting your home from other types of water damage, including preventing cracks in your home's foundation and walls.
