"Called company on Monday and got an appointment for an inspection on Wednesday. That following Monday, the technician arrived and went through each step is sealing off the concrete foundation to the water leak. The fix worked well and was put to the test with the recent record rains. Not one drop of water came into the basement."

"Thrasher did a good job on the basement foundation and installation of new sump pump. A little pricey. Workers were prompt, courteous and cleaned up when done."

"We had a different person who came out before them who was horrible and then I tried Crawlspace/Basement Waterproofing Solution because they were reasonably priced and they worked with me on scheduling their time so that they would be there when the electrician are there. They worked together with the electricians and were all done. They were wonderful. It was an all-day project but everybody worked together. Everybody showed up, everybody cooperated, and it was all done in one day with a big job. They were very good with the whole thing. The price was really good deal and all they have to do is seal from the outside to the inside. The biggest thing for us is that, they were here when everybody is here to do one thing. They are really good and we only had one problem but it was all filled up. This company gave exactly what we needed, showed up when they are supposed to, and did a great job. It was perfect. I would recommend right away to anybody before anybody else.  We were very impressed with them."

Basement Waterproofing questions, answered by experts

Thankfully, you do have a few sump pump backup options in case it fails. One option is a battery-powered backup sump pump. Another option is using a portable backup generator as a power supply for your sump pump. Unlike a battery-powered backup which has limited power, a generator can run around the clock for as long as you need it. 

Or you can opt for a water-powered backup pump, which uses your home’s water supply as a source of power. However, this may not be the best option if you find your house frequently has low water pressure.

The purpose of soffits is to circulate air, so a blocked soffit means the air in your attic becomes stagnant. This can lead to a number of problems, mostly moisture-related, that can cause damage to your health and your home. The good news is that unclogging soffits is relatively straightforward, and if your attic is easy to access, an easy DIY project.

The most flood-resistant materials you can count on in a flood scenario are concrete, closed-cell insulation, foam insulation (also known as expandable foam), pressure-treated wood, marine-grade plywood, and ceramic tile. When a material is flood-resistant, it can withstand direct contact with floodwater for at least 72 hours without being significantly damaged.

Costs depend on the area's size and condition, damage extent, and chosen method. A professional evaluation provides a tailored estimate based on specific needs.

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.
