"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 of Columbus
EverDry Waterproofing of Columbus
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."

FAQs for basement waterproofing projects in De Graff, OH
Due to the nature of basements, some level of waterproofing is necessary to prevent water from seeping in and causing damage. Some definitive signs that your basement needs waterproofing measures or needs existing waterproofing measures need to be updated include:
Water in your basement, including damp walls or puddles on the floor
Mold spots in your basement
Musty smells or odors
Warped doors or walls
Cracks in walls
Insect issues, such as cockroaches and termites
You can DIY basement waterproofing in some ways to help save on the overall costs. If your basement isn’t experiencing a lot of water but is noticeably humid, you can try running a dehumidifier that will pull the excess water out of the air. If you notice water leaking due to outdoor drainage issues, you can add downspout extensions to keep rainwater away from your home.
However, if the problem is more severe and requires a more extensive solution, it’s best to call a basement waterproofing professional to assess the treatment you need and install waterproofing safeguards properly. Since keeping water out of your basement is important, ensuring this job is done correctly the first time is best.
Damp proofing and waterproofing are both methods to help keep your basement dry. Damp proofing keeps soil moisture from entering your basement, which is helpful since your basement is underground. Waterproofing, however, keeps both soil moisture and liquid water out of the basement, which is essential, especially if you live in a wet environment. Because it’s more protective, waterproofing typically costs more than damp proofing.
Several factors dictate if you should waterproof the interior or exterior of your basement. Waterproofing the exterior of your home is a great option if you use your basement for storage, as it provides the most protection from water and water damage. If you prefer work done outside of your home versus inside, exterior waterproofing is best for you. However, interior waterproofing is often less expensive since the area is easier to reach and requires less labor.
The cost of basement waterproofing is $4,950 for the average homeowner. However, you could end up paying between $600 and $14,000, depending on factors like basement size, waterproofing method, and the region you live in.
If you live in an area with heavy rainfall, you might be paying more for waterproofing than if you lived somewhere drier since waterproofing contractors would be in high demand. Likewise, a 500-foot basement costs between $2,500 and $5,000 to waterproof, but that price rises significantly for a larger basement.
