"We just had American Dry Basement install a waterproofing system in our basement. We've had issues with water in our basement and needed a total solution so we can sleep at night and go away without worrying about flooding. Steve T from American Dry came to our house and presented us with what the solution will look like and thoroughly explained the entire process. He also answered all our questions and was always available to talk to. He is extremely knowledgeable and an excellent professional to work with. Then Wilson and his two-man crew came to do the work and they were all professional, extremely hard working and respectful of our home. They always started early and worked all day long to get the job completed. They wrapped up all items that were still exposed after we cleaned out most of our basement, used vacuums and filters to minimize all the dust and left our basement cleaner than it was before. We highly recommend American Dry Basement Systems and we're so happy we chose them over the others we received estimates from. And their price was more than competitive for what we believe is a much better solution."

"They came to remove my old concrete around my pool, and gave me a new one with speedy drains and the price was great. I was able to offer them more work cause of the price and I strongly recommend especially since they keep you up to date start to finish."

"Dean did 2 jobs for me. He waterproofed my basement and rebuilt a sewage trap door in my garage. What a professional! He showed up on time, finished the job within budget and within the timeframe promised and did a fantastic job! He was easy to communicate with during the process and kept me updated. I strongly recommend Dean and his team!"

"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.

Basement Waterproofing questions, answered by experts

A leak under your foundation from a water supply line or sewage line is likely to lead to water pooling on certain areas of your property during rainfall, abnormally fast-growing or green grass in certain sections of your lawn, and differential settlement of your foundation, which can result in large foundation cracks, windows and doors failing to operate properly, a wavy or sloping roofline, or damages or irregularities in your interior walls, including cracks and bulging. If it’s a plumbing line embedded in your slab, you’ll also likely notice above-average water bills.

The best type of basement ventilation system depends on your budget, the moisture in your basement’s air, and the types of windows you have down there. You should consider all of these factors when choosing a ventilation system. However, the most effective method for basement ventilation is an energy recovery ventilator (ERV) or a whole-house ventilation system, which preheats or precools incoming air from the outside while also managing water vapor.

Yes, crawl spaces can attract bugs, especially since moisture tends to build up in the space, and moisture attracts pests. A good way to prevent pest infestation in your crawl space is to install a vapor barrier—called crawl space encapsulation—on the interior to seal the space, along with a French drain or some other kind of foundation drainage system outside to keep runoff out of your crawl space. You can also seal foundation cracks and repair damages to cut off access to pests.

Some basement waterproofing methods can actually cause your water or moisture problems to get worse, which is why it’s so important to call in a professional who knows how to solve your underlying issue and use the appropriate waterproofing methods. An example of this would be applying latex waterproofing paint to the insides of your basement walls without fixing the water issue outside. Doing so can trap moisture in the basement walls, which can promote mold growth, peeling paint, and even damaged concrete. However, when done by a professional, the only downside to basement waterproofing is the up-front cost.

Methods include interior sealants, exterior excavation and waterproofing membranes, sump pump installation, and vapor barriers for encapsulation. Techniques vary based on the structure and severity of moisture issues.
