"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 questions, answered by experts

Most houses will have vents in the crawl space. This allows for air passage and energy retention, which in many ways can help control the temperature inside the home. If you are able to consider the cost of a crawl space encapsulation, you may not need your crawl space vents at all. 

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.

A crawl space encapsulation isn’t always necessary, but it’s a wise choice, especially if you live in an area that sees a lot of precipitation. Sealing a crawl space not only reduces damage caused by moisture, mold, and pests, but it also increases your home’s value. It can also save you money by reducing energy bills and avoiding costly repairs for structural or foundation damage.

In perfect conditions—meaning, no overexposure to the elements without roofing material on top of it—an ice and water shield can last for decades. In fact, many come with a limited lifetime warranty because they should last for a long time. If, however, the membrane is exposed to the elements during building or if there is a delay in installing the roofing material, it might only last up to 180 days if exposed to the elements. The key is to make it a layer of protection and then protect that layer by installing the roofing.

Water that pools under pavers can erode the soil foundation and weaken the paver structure. In some situations, it can also cause mold and mildew growth. If that happens, you may need to start budgeting for the cost to build and install a patio to replace the damaged one.
