"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."

"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

You don’t always need to install a dehumidifier in your encapsulated crawl space, but it might be a good idea in certain instances. If you notice obvious signs of condensation, mold, or musty smells permeating from your crawl space, a dehumidifier can help. It’s ideal for homes in humid areas.

In a worst case scenario, structural damage like rust on metal beams, rotting wood, and swelling on doors and windows can signal moisture problems that would benefit from a dehumidifier.

The foundation repair that will work best varies based on the extent of the damage, the underlying cause, soil conditions, weather conditions, and more. Permanent foundation solutions like underpinning and exterior drainage solutions are better than temporary fixes that don’t address the source of the issue. Some examples of more temporary solutions include mudjacking or slabjacking, waterproof paint, and dampproofing. The best course of action is to have a reliable foundation specialist inspect your issue, treat the underlying problem, and restabilize your foundation.

Walkout basements cost more than other kinds of basements, and can also increase your risk of leaks as well as a loss of insulation, leading to higher heating and cooling costs. Improperly installed walkout basements may lead to structural issues with your foundation, so ensure you’re working with a contractor who has extensive experience with this kind of basement.

If there is standing liquid on your concrete, remove it before attempting any of the above cleaning methods. For small amounts of water, use rags, a bucket, and a mop. For larger areas of liquid, lay down cat litter or baking soda to soak up the water first. If you have extremely large pools of water sitting on your concrete, break out the wet vac and get to work.

Flooded basement cleanup can take anywhere from a few days to several weeks, depending on the extent of water damage, the type of water involved, and the need for repairs or mold remediation. Severe cases with structural damage or extensive mold may require longer timelines. Quick action and professional help can speed up the process and reduce overall damage.
