"Very happy that we decided to work with Kyle and Hyper Flow. We had a water main leak that flooded our basement and our sump pump was not working. At 7 months pregnant, I could not go without running water to the house and needed this fixed fast. Kyle came out to provide an estimate on a Monday and the work was completed by Wednesday. He provided the most reasonable estimate for getting the work done in that quick time frame. Kyle was professional, on time, and responsive with communication."

"Cyrus was able to help me right away when I called him at 6pm on a Tuesday evening. He charged more than other companies quoted, but he was the only one who was willing to come after hours, and with a blocked sewer main, that was the most important thing. Very grateful for this company."

Basement Waterproofing FAQs, answered by experts

The best way to ensure the ground next to your home’s foundation drains properly is to divert water away from it as much as possible. While a flood wall can stop water from entering the house, gutters and spouts can help direct rainwater and melting snow away from the foundation. Keep your gutters as clear as possible from dead leaves and other yard debris so they can effectively divert water from your house. Add extenders to the spouts so the water runs out and away from your home, not into the surrounding soil.

Foundation repair uses methods such as underpinning, slab jacking, or application of hydraulic piers. Each technique is chosen based on structural needs, soil conditions, and damage extent, ensuring a stable and secure foundation.

If you decide to fill the space around your home’s foundation with landscaping materials, it’s important to consider the aesthetic as well as technical factors like drainage and protection from pests and the elements. Materials such as gravel, rubber mulch, concrete, and brick masonry are all good options.

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.

A crawl space can be as little as 42 inches below the grade of your house, but this is not always recommended in flood-prone areas. At a minimum, there must be at least 16 inches of clearance between the ground and the floor joists to access the space in an emergency.
