"I posted an initial review on 2/21/19 on a job done on 1/11/19 to fix groundwater from coming into our basement. The drainage system and sump they installed was not collecting all the water that was coming in, as we had leaking from several areas along an uneven rock ledge. I had reached out to our salesperson by phone and email and never heard back, so I was very frustrated. About 3 weeks after I posted the review, I did get a call from Jeff Allen, one of the supervisors. To make a long story short, he sent out one of their waterproofing specialists to look at the problem. We had already hired an independent mason to try to remedy the problem but he had not yet had a chance to do the job. Jeff convinced me that CT Basement systems would do absolutely whatever it took to fix my water problem. I cancelled the independent mason. Danny, a mason from CT Basement Systems came out and used a very ingenious method to divert all the water to the originally installed water guard trough and then to the sump. It is working beautifully!! I think Danny is a genius and I am so impressed and thankful for Jeff's perseverance and kindness in making this happen. I am now a very happy customer."

"Let me start by telling you my backstory. I live in a house built in 1929, it has a stone foundation. It wasn't until Hurricane Sandy that I felt the effects of a house that had no waterproofing and we had about three feet of water. We did a little bit of mitigation, and had no more problems for awhile. More recently, NY had five days of non stop rain and the walls in basement and flooring barely held it together. So that's when I knew I really had to do something. Every time we heard the weather report we would keep checking that basement and our little water pump. The water pump did ok, but we had wet vacs and worked like a team, but the water was coming up through the floors. Just a little 2-3 inches can cause so much damage. This is climate change, a lot of my friends were suffering from flooding for the first time and it wasn't going to get any better. So that was it, my husband and I interviewed four different places. They were all professional, but there was something about the detailed 2 hour interview that Scott Cort, one of their top inspectors did with us and we knew that was the place we were going to deal with. Plus he dealt with a multitude of questions from my husband and didn't flinch. He was patient, showed us exactly what they would do to protect the basement from flooding. He saw how stressed I was and just plain tired of this. It was a very comprehensive plan. Scott explained the lifetime warranty. The system is self-cleaning and requires zero maintenance. There is also a clog free guarantee. It included a PITBOSS waterpump with a wifi system and a backup battery in case the power goes out. He also told me that there would be very little dust. And there was very little dust. It only took two full days of his crew working nonstop. I was a bit nervous about cutting the walls, but he picked up the phone every time I called. If he was busy, he texted me right away and got back to me in 30 minutes. (And I call a lot). I am happy with the results. My contractor checked it out and said American Dry did a great job after dropping by to see the results. And most of all, we can sleep when it rains. We are ready!!! By the way, I have never written a review this long, but I needed to shout them out, and it was competitively priced!! Thank you AmericanDry, thank you Scott Cort. It was a pleasure!"

"These guys are true and remarkable professionals. Their attention to detail and going above and beyond is exemplary. Their pricing is extremely fair and on point I had them repair my garage door thresholds after replacing my asphalt driveway and I also had them repair four cracks in the foundation and repair my front cement steps and you would never know that there was ever an issue anywhere throughout the project I highly recommend these guys for any renovation project you may have. They are great with suggestions and how to make your project even better. They are remarkable individuals. I can’t thank them enough for the job that they did. INCREDIBLE WORK"

"Jon is professional and a man of his word. My wife and I had some leakage in our finished basement. After substantial research, I contacted several companies in the area. Jon and his crew at Eastern responded faster than every other company and offered us the best price for the least hassle. The crew works hard and fast. They were respectful of our home and property and cleaned up after themselves when they were done working. Our interior foundation drain is working great and can sleep in peace knowing that our basement is dry, even on the wettest nights.They stand by their work and even came out to install a false floor under our oil tank after we replaced it., at no additional fee. I would 100% recommend Jon and his crew for all of your waterproofing needs."

"Elson did an excellent job removing an old crumbling entrance to my house. He installed new poured concrete stairs and a side walk. They are much safer and look great. I would not hesitate to hire him again in future. He is friendly, competent and reasonably priced."

"From beginning to end the project couldn’t have gone any better. In deterring the scope of the project, they listened to all our concerns, and devised a comprehensive plan to meet all our needs, not just simply an insulation replacement. The actual work crew was very friendly and respectful of our house and property. We alway got notice when they would arrive and were always on time. They kept us informed every step of the way with pictures of their progress. They let us know early on of one potential electrical issue with recessed lighting and worked closely with our electrician a couple days later to resolve the issue prior to actual blowing in of the insulation. Overall, a first class operation all the way and we already feel the benefits."

Foundation Repair questions, answered by experts

If your concrete steps have crumbled or chipped, you can fix them by removing any chips or flakes, cleaning and wetting the affected area, applying a concrete bonding agent, and finally applying new concrete, usually in the form of Portland cement. For widespread damage, you can consider concrete resurfacing instead. For fixing concrete spalling that has led to deep damage, you might need to remove damaged material, add structural supports, and pour new concrete into a mold.

Concrete pools are very durable but can crack if not properly maintained. The most significant risk is winter weather and low temperatures when water can seep into crevices and freeze. To avoid damage, use the proper winterization chemicals, and don’t completely drain your pool. Concrete pool repairs cost around $75 per linear foot for small cracks.

Cement companies offer a wide variety of services, including delivering and pouring concrete for home foundations, walkways, patios, driveways, concrete steps, pools, pool decks, and more, plus concrete repair and patching. Most companies also have the ability to demolish and haul away old concrete landscaping features. It’s a good idea to reach out to a few different companies before hiring to make sure you choose one that can tackle the entirety of the project you have from start to finish. This method will typically save you some money over hiring multiple contractors.

If your building department catches you or a contractor doing foundation work without proper permits, they will likely put the work on hold until you secure the necessary permits, which can cause delays of days or even weeks. You can also face violation charges for construction without a permit, which can cost hundreds, depending on where you live.

Although some concrete cracks are cosmetic, others can be more serious. Cracks wider than ⅛ inch or that extend through the slab are serious and can cause structural damage. If you notice these types of cracks in your concrete patio, contact a local contractor who installs concrete patios to inspect the damage and determine how to fix it.
