"Situation resolved!!!! This started off as a little bit of water in the corner of the basement but escalated very quickly with the snow melt. Sean was here the same day I called to assess the situation and began work shortly after. They had to chop up the entire perimeter of the basement floor to install the french drains. This is definitely messy work and they never left a mess behind. All the guys were great and the work was well done and in a very timely manor. HUGE amount of stress has been lifted and thank you to Century Masonry and Waterproofing for making the process relatively painless."

"I had a previous company come in to waterproof my basement and they charged me more than Once and Done and did a horrendous job. They didn't do it correctly and more mold grew. Once and down came in, tore out the previous work and put in their system and my basement is completely dry even during the wettest months & completely mold-free. They gave excellent customer service and priced the job VERY reasonably. This is an honest company and do super work. I would give them 10 stars if I could."

"I will definitely be using these guys again for future projects. Sam gave me a reasonable estimate that was less than expected. He explained the process very clearly. He also suggested some solutions for other things he saw throughout his work. They did clean up pretty well though they left a whole bag of concrete afterwards which got wet and hardened. They were battling with the weather to finish my project and even came on a Sunday to finish because the weather was good that day. Definitely recommend!"

Basement Waterproofing FAQs, answered by experts

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.

Costs depend on the area's size and condition, damage extent, and chosen method. A professional evaluation provides a tailored estimate based on specific needs.

Rigid foam board insulation is one of the safest insulation materials for basement walls. The panels offer a moisture barrier to prevent mold and mildew build-up. At the same time, this material is also fire-resistant, so you don’t have to worry as much about a fire breaking out as you would with spray foam insulation. 

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.

The cost of basement waterproofing is $4,950 for the average homeowner. However, you could end up paying between $600 and $14,000, depending on factors like basement size, waterproofing method, and the region you live in. 

If you live in an area with heavy rainfall, you might be paying more for waterproofing than if you lived somewhere drier since waterproofing contractors would be in high demand. Likewise, a 500-foot basement costs between $2,500 and $5,000 to waterproof, but that price rises significantly for a larger basement.
