"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."

"I own a house which is around 90 years old. Its basement had compromised walls, one of which was seriously bowed. In addition, after heavy rain, the basement floor would be wet. I got estimates from three companies to correct these problems. Pivotal was a clear standout. The owner Jeff, his family members Andy and James, along with the rest of the crew make up a terrific team. Jeff and Andy visited my basement twice for long and detailed planning sessions. The actual work took 7 days for completion with James as foreman. All the problems of my basement were fully addressed. My bowed wall is now vertical, with strong supports along all walls every few feet. A complete waterproofing system was installed which feeds to my sump pump. Cleanup after completion of the work was very thorough. Bottom line: Pivotal is a totally trustworthy top quality company!!"

"They are great to work with. Communication was superior. They stand by their work. A few years ago I had waterproofing done in my basement and this time they spray foamed the cavities of the basement too. Both times they did awesome work and cleaned up too! I highly recommend this company!"

"Joe reached out quickly and with the assistance of Alupe, they were able to swiftly install a new lock & snap floor professionally over a poorly tiled/grouted situation. There was a small snafu with the wax ring and leaking water from the toilet to the basement after the floor installation and Joe & Alupe came out immediately to remedy the leak. Joe also patched a hole in our upper level ceiling AND a small hole on the outside of our home. All is well and we will DEFINITELY have them back for future services!"

"My husband and I began notcing cracks in our basement walls within the last few months so we contacted Frank to diagnose the problem. He was very knowledgeable and promptly told us what needed to be fixed. His crew began work within a week of us meeting, they worked quickly and efficiently and the job was done in 4 days. They knocked out 30 feet of our basement wall that had been damaged and the work was done in an extremely clean manner. They left the area meticulously clean. We also had 38 feet of wall on the other side of our house piered because it was settling. Frank lifted the house and piered the wall with a jacking system. We were extremely surprised as to how quickly all of the work was done and appreciated the professional manner in which it was completed. Frank even provided us a lifetime tansferable warranty. We highly recommend using Frank for any foundation repair work.

Basement Waterproofing questions, answered by experts

Sandbags are the most common and efficient way to create a flood barrier at home. Some local authorities pass them around to homes before the risk of a flood. Otherwise, you can use flood-proof house materials, like burlap or woven plastic bags, to make sandbags and fill them with sand or cat litter. Make sure that when you stack them, they’re tightly laid on top of each other, creating the effect of a firm wall against accumulating water.

Yes, a crawl space can add value to your home. However, there is a higher chance of it adding value if it is an enclosed crawl space, as this reduces issues caused by excess moisture in the home. That being said, a basement does add more value than a crawl space.

The best basement waterproofing method depends on the specific issue causing the water intrusion. For minor problems, simple solutions like installing a properly functioning gutter system to direct runoff away and grading the soil to slope away from your foundation can be effective.

If you have more significant water problems, the solution will need to be more robust:

  • For standing water on the basement floor, a floor drain or a sump pump system may be the best solution.

  • For water pooling around the foundation, installing an exterior French drain can intercept water before it reaches the basement walls.

Other effective waterproofing methods, which can be used depending on your home's specific needs, climate, and soil type, include sealing the interior walls, landscape alteration, installing interior drainage systems, and using a dehumidification system to control moisture levels.

Yes, it is generally unhealthy and can be dangerous to live in a damp basement. The damp air can negatively affect your breathing and lungs, and the moisture promotes mold growth and pest infestations. Inhaling mold spores or waste particles from insects and rodents attracted to the moisture can be hazardous. This damp, moldy air can also circulate into your main living area. It is crucial to resolve any moisture problems and implement preventative measures before using your basement as a living space.

A sewage smell in your crawl space is usually from a damaged or clogged pipe leaking sewer gasses or actual sewage underneath your home, but there are some other common causes. Moisture, from poor or damaged encapsulation or a malfunctioning sump pump, can harbor mold and bacteria, causing a musty smell. Pests can also get stuck in your crawl space and die, which causes a sewage-like odor.
