"Based on the foundation being brick, there was not the option to add weeps. Additionally in the middle of February, I did not want to excavate the exterior. Therefore the waterproofing was done from the inside. Renew added a rigid board covering onto the foundation interior which will direct moisture downwards to the new drain tile system and now the basement is humidity and moisture free. Very pleasant folks to work with too."

"Jensen Plumbing is professional, friendly, knowledgeable, and truly cares about their customers! As a new homeowner, I have had plenty of questions, and their entire team has been patient, responsive, and happy to explain things. They even took the time to show me how my new drain tile works and explain how they help prevent water from leaking into my basement. When I had a gas leak, they responded quickly and helped me get a gas shut-off valve installed that my home didn't originally have. They are currently helping me with a leaky shower and guiding me on options that will work with my existing plumbing. Their pricing is reasonable, and they make you feel like family. No question is too silly, and the staff are like talking to family friends. I highly recommend Jensen Plumbing for their expertise, outstanding customer service, and genuine care for their customers!"

Basement Waterproofing FAQs, answered by experts

Water damage always poses a primary risk of mold and mildew, but growth is not guaranteed. Whether mold develops depends on several factors, including the severity of the water damage and how quickly the area is addressed. To prevent mold, you must act fast—ideally within the first 24 hours. The process involves cleaning up all standing water and thoroughly drying the affected area. If the damage is extensive, the cleanup was delayed, or you suspect mold might be present, it is safest to assume it has grown and contact a professional mold inspector or removal expert to assess the situation.

To ensure your basement walls are waterproof, it's crucial to address any existing moisture issues before finishing. Inspect for signs of water seepage, such as dampness or discoloration, and repair any leaks or cracks. Install a vapor barrier to prevent moisture from penetrating the walls, and consider waterproofing paints or coatings.

Proper drainage systems, such as interior or exterior waterproofing, can also be beneficial.

No, your basement dehumidifier doesn’t need to be on 24/7. While it’s an excellent tool for tackling damp, musty air, especially in humid seasons, leaving it running nonstop can backfire. Over-drying the space can mess with your sinuses, warp wood, and even crack certain materials. Instead, only use your humidifier when moisture levels rise above 50%, and then give it a break when the humidity levels drop.

Yes, professional installers use weather-resistant materials to protect the dish and cabling from environmental damage.

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.
