This is a tough review to write, because the crew (Nick & Elario) were outstanding; they were professional, friendly, and their work was excellent. They exceeded my expectations -- outstanding work! This would be a 5-star review, EXCEPT -- the communication from the company is terrible. They don't answer the phones, they don't answer emails, they don't return phone calls or reply to emails. They are extremely frustrating to deal with. Interestingly, if you call in the evening when the local office is closed, Groundworks Canada answers the call, and actually does their best to help. But the South Plainfield office, fuggedaboudit. But let me end by saying, the work they do lifting concrete is outstanding. Too bad they have such a dysfunctional administrative office.

Our driveway was 6 inches lower than our garage and the walkway wasn't lined up to the driveway or patio. After a few outrageously expensive estimates from several companies and a few aggressive sales pitches I came across Concrete Chiropractor. The estimation process was simple as they asked me to take pictures and included a guide on how to do it. They followed up with a phone call and explained the process to me. They then sent me a DocuSign document (contract) and told me they would be in touch to schedule in a few weeks. When the crew showed up they again explained the process and in just a few hours everything was fixed perfectly and the price was fair. In fact they don't haggle or play games just give a fair price for the work.

I noticed some dark spots on the Sheetrock in the corner of my finished basement. I wasn't sure…read morewhat was causing the moldy looking wall. I realized that water was puddling at the bottom of the basement wall when it rained. The water was also hidden under the concrete. Even when the keyway looked nearly dry, I could feel water, mud and wet rocks under the concrete floor. Days went by and panic began to set in; I wasn't sure who could fix something like this. It would be a huge job to rip up the driveway and fix the water problem from the outside. I needed someone to fix the wall leak and the hole under the slab. It had to be done from the inside. Luckily, I found B. Altman's Waterproofing. I figured I would call and leave a message (it was already late but I wanted to put a call in and get the ball rolling) Surprisingly, the owner answered. He had me send photos of the basement wall, floor etc. Barry analyzed the situation quickly. He realized the wall had a long crack as well. He answered all my questions and described why and how leaks like this occur. He assured me that the problem was very fixable. Two days later, Barry's technician, Marcos arrived promptly at 9am. He spent the entire day fixing the problem. He cleaned out the crack in the wall and added epoxy injections all along the damaged areas. Then he filled in the cracked keyway. Marcos was a true professional, his work was clean and he kept my house neat; even making sure to use a drop cloth everywhere he worked. The job was finished in one day! About a week later Staten Island had what was called the wettest December ever. Floods were everywhere in the tristate area. It was about 2 days worth of nonstops rainfall! Two of my neighbors told me that they had to use a shop vac to dry up the rain that had entered their basements, but my basement was actually dry for once! Thank you B. Altman's for locking the water out of my house!

Usually a tube gun is used. They bunched up heavy furniture into a corner of the room and never put them back when finished. They barely spoke or understood english. No one who spoke English supervised the work. They did not air out the place after the job (and they could have) to mitigate the horrible nasty lingering smell of the sealant--in fact they didn't even warn about the smell beforehand nor leave instructions on how to deal with it AND after all was said and done the wall still leaked.. And Barry is a nasty son of a gun to deal with if you complain. Don't use him despite what the others said.

Jim and the crew from Blue Umbrella Waterproofing did an amazing job of installing a French drain in that problem room. From set up to install and to cleanup all went perfectly. Jim stayed in contact throughout the whole project. He made a frustrating time a breeze. He and his team answered all my questions and addressed any concerns I had. Im glad I decided to go with Blue Umbrella!! Thank you to Jim and your team! Update: 9/18/26 Originally I didn't have the funds to go with a battery backup sump pump system (system was reasonably priced. I was just strapped for cash) nor did I think we were going to get this much water near the house...well with this crazy weather we had with so much water, the pump did its job but I was also concerned with a power outage. I got the money together and worked with Steve and Jim to scheduled the install of a battery backup pump system. Well thanks to Steve,Jim and the crew, Willson came out and installed the unit. Now I have Days of protection if the power goes out. Thank you Blue Umbrella Waterproofing for working with me to get this done. Steve,Jim,Jose,Willson and the crew thank you so much for the work you did and putting me at ease knowing my basement is going to stay dry no matter how much rain we get. The system is a beast on keeping water out!! For anybody that needs a basement sump pump system go with the battery backup system. It only takes 30mins of a power outage to start flooding your basement if you don't have a battery backup pump system with all this crazy weather. It will give you protection and peace of mind to have one installed! Once again...Thank you Blue Umbrella Waterproofing for protecting my basement!

Can I be a waterproof specialist? I doubt it but I am much more educated on the matter. Prices are very good and transparent at all levels. Proposals are easy to understand and no reading small print, because there are none. The owner Steve will match competitor pricing if lower than what Blue Umbrella offers. A crew of four came. Jose, foreman, did a great job! He was responsible and the crew were timely. Jose even helped me reinstall the dehumidifier to the new sump pump area. They took away all the garbage too! The crew had two large trucks and seemed to have everything down to a science. One truck replaces the other once all the dirt from the basement gets loaded. My job was finished in two days because I needed additional work but this was explained to me and I had agreed to the extra service and charge. Knowing in advance is a good thing! Steve, the owner, came out to meet the me on day one. It was nice of him to come out and meet his client. After having a conversation earlier in the week, I can say Steve is very feisty and passionate about his company. During the early stages, Marvin made sure to show me an additional footer ledge was needed and I wasn't charge for something made up. Everything overt! No surprises or hidden wallet breakers! At the end of the job, a customer appreciation care box came to my attention! This review will keep Blue Umbrella's five star record on track! Great to help local businesses!
