"Having our crawlspace encapsulated was one of the most seamless processes I’ve been through. Everyone was super professional and helpful throughout the entire process. Harlan Moore did a wonderful job explaining not only how the team would encapsulate our crawlspace, but how they would do it as well. He efficiently explained all the payment options and ensured we selected the one that best fit our needs. Corey Church and his team (Tyrese Ware, Devon Plater and Gavin Grigsby) were the best. They kept me updated on the process from start to finish and I was confident I was in good hands. They found our resident black snake in the crawlspace and Corey came to the door to ask what I wanted him to do with her - and wouldn’t even show her to me until he was certain I was okay with putting eyes on her. The team had to leave early for a previous appointment the second day, but they stayed longer the third day and they were able to finish the job! These guys were very hard working, kept the no"

Basement Waterproofing questions, answered by experts

Whether interior versus exterior basement waterproofing is better for your home depends on your budget. The majority of water issues that homeowners experience in their basements are due to conditions that start outside of the home. So, to prevent those problems from seeping in, it’s better to stop them at the source using outside waterproofing methods.

Rigid foam insulation boards are one of the best insulation materials for crawl spaces. This material insulates the home well, resists water damage, and won't settle like fiberglass or cellulose. Closed-cell spray foam insulation is another effective insulation that both seals the air and provides excellent thermal protection for hard-to-reach spaces like crawl spaces.

Proper basement ventilation is very effective at reducing humidity. Without enough ventilation, your basement is prone to mold and moisture damage. Your basement should have as much natural ventilation via windows and doors as possible, and if your budget allows, you should also consider installing an ERV system to keep basement humidity levels at bay.

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.

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.
