"I had a great experience with American Dry Basements. From start to finish, their team was professional, knowledgeable, and easy to work with. They took the time to explain everything clearly and made sure the job was done right the first time. What really stood out to me was their fair and affordable pricing—no surprises, just honest work at a reasonable cost. It’s not always easy to find a company that combines quality service with good value, but they definitely delivered on both. If you’re looking for reliable basement waterproofing with a team you can trust, I highly recommend giving them a call."

"Aaron Lenker add Corbin Gillichbauer of Groundworks leveled concrete walks around my corner lot in Montoursville Pa. They arrived around noon time and were finished about 5 1/2 hours later. They did their work very professionally. They did an excellent job. I would rate their work 5 of 5 stars."

"Flooding in our basement has been a recurring problem over the years. We’ve had various companies do work for us but they failed to keep our basement dry for longer than a few months at a time and only did a semi okay job. That all changed when we hired Empire Construction Waterproofing. Chris gave me a very reasonable price for the size of our project. They had a team down there starting to work almost right away! They were incredibly professional and worked very efficiently. Once they were done they left the space in great condition. My husband and I were very satisfied with the project. The results went above and beyond our expectations, the quality was unlike anything we’ve ever seen before. It was such a pleasure working with Chris and Empire Construction Waterproofing. I have recommended them to all of my friends and family. If you’re having basement issues definitely give them a call."

"Honestly, we cannot say enough good things about Drainage Pros. They are professional, competitively priced, trustworthy, and - most importantly - excellent at what they do.
We moved into a 1920s home with major drainage problems. Four of the six original underground drains that collected water from the downspouts were nonfunctional. Our home also sat low on the property, and when it rained water flowed across our driveway, over the patio, and into our basement by seeping over the foundation. It looked like a small river coming toward our home and disappearing underneath.
AJ responded quickly to our initial inquiry and met with us on site to discuss the project. He listened carefully to our observations while assessing the driveway, patio, and grounds before sending us a detailed proposal the next day. The proposal listed several different stages and options, which we continued to discuss with him at every step of the project. AJ was always very  knowledgeable, communicative, and professional, responding to our many questions and concerns thoroughly and patiently (even when we asked the same question multiple times). Ultimately, Drainage Pros stood by their original proposal, working within budget, and they even guaranteed their work (although we don?t expect we?ll be needing the guarantee).
They tore out and had the old driveway re-graded and repaved, installed a channel drain behind part of the home, and laid pvc pipe along the entire perimeter to collect water from all six downspouts. They ran the pipe under two bluestone patios and walkways, all of which they reset carefully. They connected the pipe to our main sewer line, which required six foot plus excavations. Lastly, they reseeded the lawn (which returned nicely), and basically restored the grounds to their original condition. The paving company they coordinated with was also excellent, and they worked hard at communicating with each other to ensure that the project was completed to our satisfaction.
Personally, what I most appreciated about working with Drainage Pros is that AJ did not trouble us with all of the things that could possibly go wrong while performing such a major job like excavating and tapping into the main sewer line. He simply assured us calmly and professionally that he and his team could do the job, and they did. Perfectly.
We had previously discussed the job with a completely different (and also highly rated) contractor who appeared flustered by our drainage issues and, after charging us >$1,000 for an assessment and cleaning, was unable to offer us a written proposal or estimate without further ?diagnostics?. Do not waste your time and money, like we did. Just hire Drainage Pros, and they will get the job done.
We now have absolutely NO DRAINAGE ISSUES and strangely even look forward to when it rains so we can see how beautifully the water flows down the driveway, into the drains, and away from the house. If you are on this site searching for a drainage specialist, perhaps you can appreciate this.

"My basement is dry. After work was completed, I still had water coming through my walls. I called and they came back to put a waterproof/plastic sheet up with tape that tied into the system they installed. We will see how long that lasts but for now the basement is dry. With that being said, everything that was in my basement is ruined. Everything is covered in about an inch of concrete dust. My wife’s inventory for her business is ruined. Our Christmas decorations are ruined. They put up plastic to protect our stuff but that clearly did nothing. Definitely clear out any belongings you want to use in the future and expect an inch of concrete dust when done. Thus, a bit of a mixed review."

"lWell. The basement was a damp dungeon prior to installation. Now, it's dry and usable. We also had a contractor install a new powder room and floor and lots of closets. We can now use the basement for extra living space.

Basement Waterproofing FAQs, answered by experts

A walkout basement is considered to be partially below grade because at least one wall is entirely exposed. In some cases and in specific municipalities, inspectors and appraisers will still count walkout basements as below grade, which means the space can’t serve as living space or be rented out. If you intend on using the area as living space or a separate apartment, you should check with your local building department to make sure it’s legal to do so.

If you decide to fill the space around your home’s foundation with landscaping materials, it’s important to consider the aesthetic as well as technical factors like drainage and protection from pests and the elements. Materials such as gravel, rubber mulch, concrete, and brick masonry are all good options.

While water in your basement is unlikely to make you sick unless it’s coming from a sewage backup, mold is likely to start to grow in wet areas within 24 hours, and mold can make you sick. According to the Centers for Disease Control and Prevention (CDC), inhaling mold spores can cause allergy symptoms, including runny nose, itchy eyes, difficulty breathing, wheezing, and itchy skin. Individuals with pre-existing respiratory issues like asthma and immunocompromised individuals are at an elevated risk of symptoms when inhaling mold spores.

There are a few downsides to a wet room, the most important of which is the risk of mold growth from the moisture and humidity. Standard bathrooms can have the same issue, but wet rooms are more likely to experience problems because water is less carefully contained. You also have less privacy since the entire bathroom is open, and the room must include waterproofing, which makes wet rooms more expensive to install than regular bathrooms.

Water can seep into porous materials like wood beams, floor joists, and roof rafters within minutes, but they’ll need to see prolonged exposure before you have structural damage. Mold can start growing within 24 hours, and mold can eat away at the structural components over time. Wood rot is more of a concern, though. Wet and dry rot are fungal infections that set in in moist conditions and rapidly deteriorate wood, causing major structural damage within just a few months in some cases.
