"They advice, and had all our questions answered on sensible and affordable options. Very knowledgeable, prompt, polite, efficient, and thorough team! We are happy with their waterproofing services in our basement (fast sump pump and a grate trench with a discharge line that goes 15 feet to the outside bubbler) as well as crawl space shield installed under our addition. It works well, and Pioneer checked a month later and a year after for inspection and cleaning. A+ work and workers."

"We had 4 basement waterproofing companies come into our home to do an assessment of our basement. We are updating our home and finishing our basement. Although we only had occasional and minor water leaks we wanted to protect our investment. Our time with Mike, Jason, and the rest of the team was professional and informative from the first moment. They were responsive with our estimate, fair with their pricing, and willing to answer our questions along the way. The crew arrived on time and ready to get the project started. We had a couple of large items that we needed help moving and they assisted so that we could keep the basement clean. The work that was performed was done so with care. The basement was kept as clean as possible, and our input was taken into consideration along the way. Hands down thankful for the experience and piece of mind that we now have."

"Gerald took the time to understand my needs for making a basement for finished. He explained the options. We decided on self leveling concrete and covering the exposed French drain we had. We decided on a schedule, everything was done on schedule. I now have a Waterproof basement floor with total usable space. Extremely satisfied with the teams work."

"Erick is a truly good man who stands by his word/price. I had two bathrooms remodeled and I am thrilled with the end result. Erick made sure that any inconvenience to my family was minimal and at the end of every day their clean up incredible. After getting three other estimates, I had Erick come over to estimate the price and his price was 20% lower than some of the other estimates. Erick is my go to contractor, I trust him and I intend to have him do some more work this spring. Feel safe hiring Erick, you will not be sorry."

"Contacted Mark within 3 days he was at my home and providing a detailed quote. Might seem small but he was the only one out of 4 contractors who actually measured the space to provide an accurate and detailed estimate. He while discussing what I wanted with me made many recommendations and even mentioned ways to get the job done but at a lower cost. He had the estimate to me within 2 days and it was super detailed and broken down with 3 different ways to complete it. He was on time daily as was his crew. Work areas were cleaned daily. He closed up a broken window for us, redid a dirt floor with drainage and concrete, repointed and waterproofed our basement foundation, ripped out and fully replaced basement access stairs. He even noticed a window that was broken we didn’t and closed it up for no charge. He added a drain to the exterior steps at no charge wasn’t in contract he just knew it was needed, the steps he replaced had asphalt around them and he even repaired the asphalt at no c"

Basement Waterproofing FAQs, answered by experts

Mold and mildew are the things in basements that actually cause the musty odors, but moisture is the underlying issue that causes mold and mildew growth. Addressing moisture and water problems and then removing materials that are moldy are some of the best ways to get rid of the musty odors. Preventive measures after that—like installing air fresheners and a dehumidifier—can help keep musty odors from returning.

Egress windows or doors are required in finished basements to meet safety and building codes. If your basement is unfinished and used as a storage space, egress windows are not required, but anything considered a habitable space must have an additional point of egress in addition to the stairs.

Yes, it is possible to over-dehumidify a house by removing too much moisture from the air. This can create an overly dry environment that negatively affects those with respiratory or skin issues, and may cause your skin, hair, and sinuses to feel dry. However, this is unlikely to happen with most modern dehumidifiers, as they are equipped with moisture sensors and adjustable settings. These features allow the unit to pause automatically when the desired humidity level is reached, preventing the air from becoming uncomfortably dry. In contrast, older or more basic dehumidifiers left running for too long could potentially over-dry the air. To avoid this, aim for a balance between removing excess moisture and maintaining a comfortable environment. You can often monitor your home's humidity levels using a modern thermostat for guidance.

A sump pump can be added to an existing basement. To do this, you will need to use a jackhammer or sledgehammer to break up the concrete and dig a pit. You will also need to create a hole in your basement wall to run the discharge pipe through.

There are a few downsides to a wet room, the most important of which is the risk of mold growth from the moisture and humidity. Standard bathrooms can have the same issue, but wet rooms are more likely to experience problems because water is less carefully contained. You also have less privacy since the entire bathroom is open, and the room must include waterproofing, which makes wet rooms more expensive to install than regular bathrooms.
