"It went well. They are being professional in their follow-up as they are trying to have us install an expensive basement drainage/pumping system. We haven't decided yet, as it will be part of our basement gut/rehab project."

"This business was professional, communicative, and on time from my initial inquiry to when the job was performed. When I initially called, they were able to get someone out to provide a quote within 2 weeks and had me booked within another couple weeks. I was provided a quote online, and that's what I ended up paying. No fine print. Everything was completely transparent. William and another person came to do the actual sump pump installation. They were on time and finished a rather challenging installation (the pipe exit needed to be in a different room than the actual pump) within 4 hours or so. He explained everything to me clearly and was friendly, courteous, and professional. I would absolutely recommend these guys if you're looking for any kind of basement repair/waterproofing."

"We hired Leal Restoration to clean up water damage on three floors of our house. They came early on a Saturday morning, worked all weekend and finished the job on Monday. This included drying out the area, removing debris, and replacing a ceiling. The work was done efficiently and carefully. Leal turned a disaster area into a clean and back to normal living space in 3 days. Amazing!"

Basement Waterproofing questions, answered by experts

A plastic vapor barrier should completely cover your basement to prevent water from penetrating through the walls. This typically goes before installing insulation to prevent moisture from building up and becoming trapped on the inside of your insulation, where it can collect and lead to mold damage. Installing insulation after the vapor barrier allows for any moisture to exit the walls for better ventilation.

Generally, moisture barrier padding costs $0.75 to $1.50 per square foot, varying by brand and mix. That’s a lot more than standard padding, which runs $0.25 to $0.90 per square foot. The price difference between these two options might seem steep, but think of it as insurance against future carpet replacement costs and subfloor damage. If you have pets or kids, that extra investment in high-risk areas like your living room often pays off.

You should take care of any sign of water in your basement, whether it’s dampness after heavy rain or puddles of water on the floor. Besides potentially causing a health hazard, the moisture can damage your home’s structure and foundation. Furthermore, mold can grow quickly and spread throughout the rest of your home. With mold remediation costs ranging between $1,200 and $3,400, it’s best to avoid mold issues by fixing the leak.

Whether to waterproof your basement from the interior or exterior depends on several factors, including your budget.

Exterior waterproofing is generally considered the superior method because it stops water at the source, preventing it from seeping into and damaging your basement walls. This approach offers the most protection, making it ideal if you use your basement for storage.

By contrast, interior waterproofing is often less expensive and requires less labor because the area is more accessible.

For maximum protection against water leakage and moisture, applying waterproofing measures to both the inside and outside is the best solution. However, if you must choose only one, stopping water from the outside is the most effective approach to preserve your foundation and prevent damage.

Yes, it’s worth it to repair a crawl space foundation, even if the issue seems relatively minor. Foundation problems often get worse and more expensive to fix if you leave them untreated. Additionally, your entire home, from the framing and flooring to the roof system, relies on the foundation for even and level support. Issues with your foundation will almost always manifest as problems in and above your living space, so it’s important to find a solution.
