"I called Hyper Flow at around 7:30am, and James, their VERY helpful tech, was at our house by about 9:15. He promptly identified the problem (which was a smaller issue than we had feared) and got it resolved very promptly. He did NOT try to upsell us on anything, but we requested that he run a camera through our pipes to see if there was anything further to be concerned about. Fortunately, there was not, and he walked me through the video and showed us that our lines are in pretty good shape. Terrific service. We will definitely use these guys again."

"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

The least expensive basement waterproofing methods include grading soil away from your home, installing downspout extenders on your gutter system, and applying a waterproof paint on the interior of the foundation walls. Installing a French drain is a relatively inexpensive method if you do the work yourself, although it’s labor-intensive and can be challenging to install properly.

Crawl space foundation problems can stem from a few different issues, but the most common are moisture and water problems and soil instability. Moisture and water issues are often a result of poor drainage, which can lead to water intrusion and soil expansion and contraction, leaving your foundation under added stress. A few things can cause soil instability, including poor drainage, karst landscapes and resulting sinkholes, and poorly compacted soil during construction.

Anything having to do with the structure of your home, such as raising the ceiling, is usually the most expensive part of finishing a basement. Another project component that could be a surprisingly high expense is adding an exterior entrance. 

The cost of a walkout basement can be anywhere from $5,000 to $35,000.

Covering the dirt floor in your crawl space with a vapor barrier helps insulate the space and improve the air quality in your home. It protects your crawl space from pest infestations, excess moisture, and mold growth. It also makes the crawl space less dusty, which means there’s a lower chance of dust mites breeding and causing allergic reactions in your home.

Water damage always poses a primary risk of mold and mildew, but growth is not guaranteed. The chances of mold developing depend on several factors, including the severity of the damage and how quickly the area is cleaned and dried. To prevent mold, you must act quickly—ideally within the first 24 hours. Clean up all water and thoroughly dry the affected area. If the damage is extensive, you were unable to address it immediately, or you suspect mold has already started to grow, it is best to assume it is present and hire a professional mold inspector or removal expert to assess the situation.
