"ErieHome waterproofed my basement. The crew was polite, kind, and came in, did an excellent job in 3 days by digging a trench on the inside of the basement, removing the dirt from the bottom of the foundation, installed corrugated tubing, rock and then cement. They also installed a Humidex airpurifier and new sump pump with a backup pump. They cleaned up afterward. Any questions I had were answered in a respectful manor. I now have peace of mind knowing that I no longer have to monitor weather forecasts for rain or have to clean up anymore incoming water. The system is warranted for the life of the house and included within the price, which increased the value of my home."

"I have an old house with part crawlspace and part basement. So, it didn't fit the waterproofing "system" some of the other companies wanted to sell me. Kyle suggested a fix that fit the specific water intrusion problem for my old house, and replaced the sump pump. This cost far less than rebuilding my basement to fit a "system". Crossroads Foundation Repair's communication and recordkeeping is very clear and professional. I would recommend this company without hesitation."

"We had a challenging project with water removal and structural support issues. Our crew of Tim (Foreman), Marq, Jayshawn, and Devon worked diligently to install a new drainage system and support beam for the house, spending late nights to get the job done. Thanks to (Manager) Cornell for his assistance on this complex project. Matt E"

"We had a basement that always had water in it almost year round. We decided to sell the house and move to North Carolina. Still trying to sell the home we decided to have a French Drain System put in with a bleeder line, as it would not sell as it was. The Stay Dry team was excellent from start to finish. Their team was professional and was accommodating to the fact that we needed to keep the home clean due to selling it and took extra steps to ensure no contamination spread to the rest of the house. After the job was done I have had zero issues with water and we are closing on our home today. Thank you so much for your hard work and courtesy Stay Dry! Pictures below are just after washing and cleaning. It appears wet but was completely dry the next day."

"We sold our home and we needed a waterproofing expert to come out and inspect some basement cracks for water leaks. We needed this done pretty quickly and other companies we had contacted were all booked up. I got in touch with this company and Marty gave me a call back and offered to come by in the evening after he was done with his last job of the day to take a look at this for us. Right then I knew we had picked the right company. As a business owner, I really appreciated him going this extra mile. Marty didn't have an opening until the following week but knowing we needed this done pretty quickly he got there to inspect our basement quickly. He was very knowledgeable and just a great guy! We would definitely recommend Marty and this company for any of your basement waterproofing needs!"

Basement Waterproofing questions, answered by experts

It’s not the number of weep holes that should be of concern to builders but rather their spacing. Weep holes are usually spaced anywhere between 16 inches on center when using round tubes or wicking materials and 24 inches on center when using open-head joints. This is a more conservative spacing than the 33-inch maximum spacing on center that’s mentioned in the International Residential Code. All in all, the total number of weep holes a brick exterior should have will depend on the size of the structure.

Yes, you can finish a basement that leaks, as long as you address the leak first. Before finishing a basement, you’ll need to repair any cracks in the walls and waterproof the basement to prevent future leaks. It’s much harder to clean up a water leak from a finished basement than an unfinished one, so preemptively addressing any leaking areas prevents expensive repairs in the future.

Whether to waterproof your basement from the interior or exterior depends on several factors, including your budget.

Exterior waterproofing is generally considered the superior method because it stops water at the source, preventing it from seeping into and damaging your basement walls. This approach offers the most protection, making it ideal if you use your basement for storage.

By contrast, interior waterproofing is often less expensive and requires less labor because the area is more accessible.

For maximum protection against water leakage and moisture, applying waterproofing measures to both the inside and outside is the best solution. However, if you must choose only one, stopping water from the outside is the most effective approach to preserve your foundation and prevent damage.

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 best basement waterproofing method depends on the specific issue causing the water intrusion. For minor problems, simple solutions like installing a properly functioning gutter system to direct runoff away and grading the soil to slope away from your foundation can be effective.

If you have more significant water problems, the solution will need to be more robust:

  • For standing water on the basement floor, a floor drain or a sump pump system may be the best solution.

  • For water pooling around the foundation, installing an exterior French drain can intercept water before it reaches the basement walls.

Other effective waterproofing methods, which can be used depending on your home's specific needs, climate, and soil type, include sealing the interior walls, landscape alteration, installing interior drainage systems, and using a dehumidification system to control moisture levels.
