"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!"

"I was having a hard time getting financing from the big box lenders but Mark was able to find me one and at short notice. When it looked like the deal would fall through because of title issues from the seller, Mark offered his guidance and expertise and was right there throughout the whole process. The whole 5 months! No call was to early, late or frequent. Mark was always accessible and immediately responsive. A man of his word. This property virgin and veteran is now living the American dream thanks to Mark Principi and the Central Lending staff. I would definitely recommend."

Basement Waterproofing questions, answered by experts

You can seal a concrete slab by cleaning the surface, filling in any cracks, etching the surface, applying a sealer, and letting it dry. Concrete slabs don't typically need sealing, but you can use a topical concrete sealer if you notice signs of water damage. If you haven't already fixed the cause of the leak, then you'll want to repair the plumbing before you seal a concrete slab.

In perfect conditions—meaning, no overexposure to the elements without roofing material on top of it—an ice and water shield can last for decades. In fact, many come with a limited lifetime warranty because they should last for a long time. If, however, the membrane is exposed to the elements during building or if there is a delay in installing the roofing material, it might only last up to 180 days if exposed to the elements. The key is to make it a layer of protection and then protect that layer by installing the roofing.

Some basement waterproofing methods can actually cause your water or moisture problems to get worse, which is why it’s so important to call in a professional who knows how to solve your underlying issue and use the appropriate waterproofing methods. An example of this would be applying latex waterproofing paint to the insides of your basement walls without fixing the water issue outside. Doing so can trap moisture in the basement walls, which can promote mold growth, peeling paint, and even damaged concrete. However, when done by a professional, the only downside to basement waterproofing is the up-front cost.

The primary downside to crawl space encapsulation is the high cost, which can be several thousand dollars. Additionally, the process can make future repairs more complicated by limiting access to plumbing and electrical wiring within the crawl space. Encapsulation also requires sealing off any vents, which can be a disadvantage for home designs that benefit from the airflow they provide. It's recommended to consult with a crawl space contractor to determine if the benefits outweigh these potential drawbacks for your specific home.

The least expensive basement waterproofing methods include grading soil away from your home, installing downspout extenders on your gutter system, and applying a waterproof paint on the interior of the foundation walls. Installing a French drain is a relatively inexpensive method if you do the work yourself, although it’s labor-intensive and can be challenging to install properly.
