"I wish I had hired them first! I hired another company to fix my moving bowed and shearing basement walls. They were primarily a waterproofing company, but said they had the solutions to my issues. 3 months after they were complete, my walls cracked and shifted again. (Note, in the attached photos, the patchwork quilt on the walls was the OTHER company.) OBA fixed my issues the correct way. And they were great at every step. The work crew Caleb, Delontae, and Dylan were fast, efficient, and cleaned up when they were done. Caleb made sure to explain what was happening as they did the work and ask if I had questions. The work was thorough, and I feel good about it. And even better, they'll be out in 6 months to ensure everything is working as it should and make adjustments if needed."

"Greg the inspector came out, nice guy very knowledgeable, I spent 14800 in waterproofing and mold removal, new sump pump and a air purifier. Greg and I went over everything the crew was going to do. Well where the water issue I was most concerned about , they side step and only put the drain tile down the middle and not at both sides. Stay Dry ended up sending 1 person to put tile in on both sides and fixed that issue, now I am having water issue where I was not having issues before and come to find out where my water line comes in they just put gravel under and did not put the concrete back in that area. So now I have a new leak and I can't seem to get this company to come back out for a 3rd time to fix this issue. Also I have water coming up from the newly concrete floor, I was told that the concrete has to cure for awhile which I understand that, but I don't think it should be seeping up along the cracks where the new and old concrete meets. Waiting on this company to correct."

"There wasn't a clear job understanding given to me on which way I should go with the job, either inside versus outside of the basement walls. They did do the outside walls but didn't acknowledge that the other side (front area) would also have water issues. We had another water leak again, and a lot of water came in the front. They didn't solve my issue, and then they didn't offer a discount to do the inside. They left a muddy mess on the outside of the first job as well, and the steps were also muddy when they put in the beams. I went with competition for the second part."

The cost to finish a basement is $18,400 for the average homeowner. However, this cost could be as little as $2,800 or as much as $34,500, depending on the basement size and the materials needed. If your basement is already outfitted with electrical and plumbing, expect the cost to fall on the lower end.
For example, the drywall cost for this project averages around $1,750, but other features, like hiring a plumber, cost between $45 and $200 per hour.
The cost to remodel a basement is between $12,100 and $33,400 for the average homeowner. The price you pay can be as little as $3,500 or as much as $50,200, depending on the size and condition of your basement and the type of remodel you're doing.
If you're doing a simple project like adding a home office to your basement, you can expect to pay anywhere from $500 to $3,000. However, if you're adding a bathroom, which is an extensive project, you can expect to pay between $6,600 to $16,500.
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.
Although homeowners often use the terms basement remodeling and basement finishing interchangeably, they are quite different terms.
Finishing a basement is the process of taking a basement space that is not habitable and adding elements to make it usable. This includes adding plumbing, flooring, and insulation.
Remodeling a basement means taking an already existing finished basement and changing it, often by adding or removing walls, adding plumbing, or changing the existing flooring.
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.
