"Having to go through water problems in a basement is stressful but I am so glad I went with this company. Every person I interacted with was competent and professional. Larry was my first point of contact and he was incredibly knowledgeable and contacted me regularly to check in. I had scheduled multiple quotes but Larry sold me instantly because of his knowledgeable and straightforward communication. Todd, the owner, was so kind and you can tell how thorough he is about the work he does. He took the time to explain things to me and even catch things outside their job scope to make me aware of. He was incredibly fair with the pricing of the job. Nick and Dave were the two I interacted with the most because they did a majority of the labor. They were the best. They were respectful and knowledgeable. They took a lot of time to keep me updated and offer guidance for the long term care of my home. Having them working in my home never felt inconvenient. I could not have been more pleased with them or their work. I would highly recommend this company and the team they have assembled. Thank you for saving my home!"

Basement leak repair services FAQs
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.
