"Absolute WORST experience I’ve ever had with a company! They are extremely predatory and convinced my 63 year old mother that she had to sign the contract THAT DAY, and she didn’t even understand what she was signing! The first day they were scheduled to do the job, they showed up hours late, and said they “weren’t the right crew to do the job”. We then had to wait a couple weeks for a different crew to come, and when they came they said they weren’t the right crew to do the job either!! 2 weeks later, ANOTHER crew came and said THE SAME EXACT THING!!! So after 3 times of getting the runaround, I was completely FED UP with this horrible company and decided to cancel the contract. They FINALLY did let me cancel, but are demanding we still pay $600! After all they put us through over 3+ months, they had the nerve to charge us $600 for an outlet! PLEASE AVOID THEM AT ALL COSTS! All they care about is dollar signs, not about the QUALITY of their work or customer service."

EverDry Waterproofing is the nation's leading residential basement waterproofing contractor. Since 1983, EverDry has provided full-service waterproofing to thousands of satisfied customers.

"The initial work seemed OK, but it quickly became clear that there was still water leaking through the basement walls. After several phone calls, an employee returned to inspect the walls and agreed that the exterior work needed to be redone. I pointed out that plastic pipes had been left exposed in my yard, without drainage to the street. He agreed that this wasn't acceptable. I called multiple times to set up repairs. My calls were not returned. I obtained the number of Joey, the production manager, spoke with him after several attempts, and sent him detailed texts and photos. No return visit materialized. Over the course of the next several months, I called the company multiple times. They actually visited my home a total of 9 more times, but they showed up without a crew, with one guy and a shovel, or saying they didn't have the equipment for the job. Finally a single employee with a shovel appeared, unscheduled, buried the pipes, and said he corrected the plumbing from the sump pump. Unfortunately, he didn't connect the pipes, and the pop up is 8 feet from my porch. Now a fountain erupts from the drain along side the house, and gallons of water discharge along the basement wall, as well as from the pop up. The soil along the foundation has eroded, and after a rain there is standing water for days in front of my porch. This brand new problem has lead to the interior walls originally water damaged, to become wet again, and a wall that was NEVER even damp before is now soaked, and the dry lock paint has bubbled up. Recently a manager came to look at the situation, and said I would be notified of when the repairs would take place. A couple of weeks later, I called, and managed to get the work scheduled. A crew is to come out June 5th. I however, have ABSOLUTELY NO CONFIDENCE THAT THE WORK WILL BE PROPERLY COMPLETED AND DAMAGE THAT THE COMPANY HAS CAUSED WILL BE REPAIRED. After 18 months of excused, shoddy workmanship, untrained employees that have made matters worse, and now new damage, I am beyond frustrated and angry."

"For the homeowners who discovered mold in their home, and are stressed and worried about the potential cost of the eradication process, you need not look any further than these guys! Craig showed up promptly on the day day and time of our appointment, and my wife and I were immediately impressed and comfortable with his warmth and knowledge! During his assessment, he took his time pointing out the obvious areas and certain problems we never noticed! He did this not to frighten or pressure us, but being informative about the reason for for the presence of the mold! But what shocked us was the total cost of eradication...it was almost half of what 2 other companies had quoted us! His crew of young men worked tirelessly and were friendly and courteous to a fault. No complaints about their cleanup efforts either! We would highly recommend this company in a heartbeat! Ray & Lisa Jones, Delaware, Ohio"

Basement Leak Repair questions, answered by experts

Permits may be required for major repairs, structural work, or electrical and plumbing restoration after a flood. Check with your local building department to determine permit requirements and associated fees for your flooded basement cleanup project. Obtaining the correct permits helps ensure work is done safely and up to code.

To ensure your basement walls are waterproof, it's crucial to address any existing moisture issues before finishing. Inspect for signs of water seepage, such as dampness or discoloration, and repair any leaks or cracks. Install a vapor barrier to prevent moisture from penetrating the walls, and consider waterproofing paints or coatings.

Proper drainage systems, such as interior or exterior waterproofing, can also be beneficial.

If your basement often leaks after heavy rain, it’s probably caused by hydrostatic pressure. When the ground is saturated with water, it can put pressure on the exterior of your home’s foundation, causing cracks in the basement wall and pushing water through any existing weak spots. Over time, hydrostatic pressure can cause structural damage to your home.

Mold and mildew are the things in basements that actually cause the musty odors, but moisture is the underlying issue that causes mold and mildew growth. Addressing moisture and water problems and then removing materials that are moldy are some of the best ways to get rid of the musty odors. Preventive measures after that—like installing air fresheners and a dehumidifier—can help keep musty odors from returning.

If you’ll be digging up your floor to get access to your pipes when putting in a sewer backflow preventer, this would also be a good time to take care of any other plumbing issues or renovations. For example, you could install additional pipes for a basement bathroom. Since the floor will be sealed over with concrete when you’re done, now’s a good time to take care of those bigger tasks.
