"We had our basement waterproofed in May 2019, the crew was out for 3 days. They also did some landscape grading. It's been 1.5 years and no problem. Very professional company. If I have any questions Carl or his wife, Jayna, respond promptly. I would highly recommend ABC for waterproofing a basement."

"I would strongly recommend Kris Weaver and Baker's Waterproofing. Kris is extremely knowledgable about basement waterproofing, there's that. But he also did an excellent job of aligning scope and our budget. Baker's Waterproofing was highly recommended to us from friend and Kris exceeded all our expectations. He appears to be a top notch human being and we hired Baker's immediately. We are looking forward to getting started on the work and resolving our basement waterproofing issues."

"Highlander exceeded my expectations! Mr. Kevin Adams (Senior Inspector), did a thorough assessment of my basement and garage needs, clearly answered all my questions and proposed an easy to understand solution in writing. Mr. Cameron Shoemaker (Customer Care) made me feel like I was his most important customer ever. He kept me informed throughout the entire project and gladly worked with me when I had to postpone the start date of my project due to personal reasons. Wesley (Foreman) and his crew showed up on time and worked tirelessly to get the job done right and on time. When I brought up a couple of concerns at the end of the project, they quickly and without hesitation did what needed to be done to keep me satisfied. Great company and people who are 100% customer oriented!"

Basement Waterproofing questions, answered by experts

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.

Encapsulation can take the place of crawl space vents since it protects the area from moisture and air all year round. Determining whether you should open or close crawl space vents can be complicated since it often depends on the weather and humidity. Skip this step by investing in crawl space encapsulation whenever possible.

One handy thing about whole-house dehumidifiers is, once installed, you don’t have to worry about placement or changing the dehumidifier’s position. But if you are using a portable dehumidifier, we suggest keeping it away from walls, vents, and furniture. It needs a central, unobstructed spot with access to lots of air to do its job.

Although the two terms are closely related and often used interchangeably, pier and beam foundations and crawl spaces are different things. A pier and beam foundation is made up of concrete piers and wooden beams and creates a space under the home known as a crawl space. There are several types of foundations that create crawl spaces, often collectively known as “crawl space foundations,” but the crawl space itself is separate from the foundation. 

Underfloor insulation alone will not cause moisture and mold, but improper installation can. Although the purpose is to seal any drafts, your subfloor still needs ventilation. If you seal the area too tightly and prevent all airflow, this can cause moisture to get trapped. This moisture eventually leads to mold and—if your floors are wood—rotting.
