"In children’s books, the story always ends, “happily ever after.” Home projects do not always end that way. I contacted several companies associated with “solving problems with wet basements” and was confronted with the problem that each company focused only on one of the problems, but my project involved not just substantial water seepage under the front wall of a 43 year old home, accumulated mold, installation of drainage at the down spout, replacement of the moldy and worn carpeting, and replacement of original ceiling tiles in the associated rooms (utility, study). Basement Systems offered services that included all, each service was clearly documented in the contract, and each was explained noting a range of prices. There was no pressure to sign the contract so I had time to consider not only which company to choose but also which available service best met my immediate and long term needs. I hired Basement Systems and was placed on the work schedule. A week before work was scheduled, I received a complete schedule and what my role was in preparation. When I had questions, Mr. Dave Ryan, project manager immediately clarified. The work crew arrived as scheduled, removed from the immediate work area furniture, books, etc, covered all with plastic, covered the floors upstairs with plastic and initiated the project. I was onsite only the first day but had no anxiety leaving the crew. They were carefully supervised by the foreman. A bin for the construction debris was so helpful as I began discarding items from the attic as well as the shed in the backyard. I officially began downsizing. The work was scheduled for one week but completed in four days. I was quite surprised when I arrived home on the fourth day and saw all the furniture replaced and the rooms swept clean. This not yet the ending of this story. While discussing the project with the estimator, he suggested hooking up my dehumidifier to the installed sump pump system. It was definitely not in the contract I signed but an important service given my current physical limitations. A few days after completion of the project when I answered an email and survey as to my satisfaction with the work completed, I mentioned this service. Without hesitation, Mr. Ryan agreed to hook up my dehumidifier noting accurately had it been in the original contract, it would have been done. I believe I have my “happily ever after” ending. If things need fixing or altering, I know I can depend on Basement Systems to make it right. In my experience, this is an exceptional company with employees dedicated to providing service."

You’ll get both in S&J. As a family owned and operated business located in Howard County, MD we have been helping homeowners in all of Howard County MD, parts of Carroll County, Baltimore County and Northern Anne Arundel County Maryland and surrounding areas with their home improvement needs for over 20 years.
"We have used S&J Painting and Remodeling many times over the past 5 years, most recently (spring 2025) for handyman services. S&J provide services for a full day, so we typically accumulate a few projects. Our most recent project included replacing two faucets, fixing a very loose banister, repairing a hole in the drywall, as well as a few basic jobs, hanging pictures and installing bathroom fixtures. I expected to paint after the drywall and banister were repaired, but they took care of it for me. When replacing one of the faucets they found the supply lines were old and rusty. They went to Home Depot, purchased new supply lines and installed them at no extra cost. While there they picked up some brackets to secure some other loose pipes they happened to see while in the utility room. We really appreciate the extra attention to detail and doing more than we even realized needed done. We are already accumulating new projects. Scheduling and workday communication is excellent."

"I recently hired Budget Waterproofing to address ongoing moisture and standing water issues in my basement, and I couldn't be more pleased with the results. Before their team stepped in, I was dealing with a musty smell, mildew buildup, and even standing water after heavy rains — it was a persistent and stressful problem.

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.
