I needed push piers to stabilize my home's foundation, and after getting several quotes, I chose…read moreGroundworks. Their pricing was similar to the competitors, but what set them apart was that they offered unlimited pier depth per section. Other companies had limits--for example, up to 20 feet, then an additional charge per foot after that. I'm glad I went with Groundworks because several of my piers ended up going 90 feet deep across 16 sections. With another company, that could have cost me significantly more. I also had their gutter guard system installed (similar to a French drain, though they claim it's better), along with a vapor barrier and mold treatment. I will say, if you have a serious mold issue, I'd recommend hiring a dedicated mold remediation company instead. I did have an issue with the mold spray, but after calling a couple of times, I was able to speak with a manager who surprisingly took my concerns seriously and resolved the issue. The salesman who came to my house, Randy S., was excellent--very thorough and knowledgeable. He always answered my calls and would text be back in a reasonable timeframe. One thing I didn't like was the same-day discount tactic. They present you with a price, then offer 10% off (or whatever discount they choose) if you sign that day. It puts pressure on you to make a major decision on the spot, which is difficult when you're spending over $50,000. There is a three-day cancellation window, but some people may see the discount as more of a sales tactic than a real benefit. I also want to mention the foreman on the job, Jose G. He was great--he answered all of my questions and even let me watch and learn a little while they were working. Overall, I was very pleased with the experience. Their warranty is transferable, which is a nice bonus, and hopefully I won't have any more issues going forward.

Randy came by to evaluate for possible cracks in our foundation that were causing a moisture…read moreproblem on the inside of our house. He arrived on time for the appointment, was courteous, and professional and very knowledgeable about his specialty. He spent 2 hours explaining all the causes and possible solutions to our problem. He gave us all the information we needed as we decide how to move forward.

My basement kept having puddles of water alongside the partition wall between my neighbors home and…read moremine.. i've asked her to address it but she was stalling so i had to take matters into my own hands. I contacted 2 waterproofing companies, B Altmans being one of them and decided to go with them for their reasonable price and the extent Barry went through to explain to me everything in detail over the phone. He was on vacation and still answered phone calls! From start to finish, he checked in with me, and explained thoroughly the whole process. He even referred me to a public adjuster after we found out this water problem was stemmed from my neighbors broken water pipe! Marco was professional, a very hard worker and always on time! He finished the whole job himself in just a matter of days. Altmans also provides lifetime warranty on their work which is a huge plus. I would totally recommend them to family and friends!!! Photos show water damage and mold, and the waterproof barrier Marco created to help block out water!

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!

I wish I could give zero stars for this company. My driveway was replaced in early fall and the…read moreentire experience has been a nightmare. For starters, the company's trailer broke down on my curb due to a flat tire when the driveway was initailly being replaced. After leaving the trailer there for days, when the company finally sent someone to pick the trailer up, the worker ended up ripping my grass up when trying to move the filled trailer. The worker then dumped the dirt contents from the trailer on the ground in front of my house and left the dirt there for days on end before the company finally sent someone back out to collect and remove the dirt. There is also already grass growing up through the driveway. I have attempted to have the company come back and fix the driveway and have been given every excuse in the book when they have failed to show up to replace their shotty work. I've been told, "the foreman who is on your job is out on family leave", "there's been a death in our crew", "we're first responders and other jobs are more important", "if the person in charge of your driveway can't make it on the day we've scheduled, I promise the boss himself will be out to fix your driveway". I'm still waiting on the driveway to be fixed and now the company is no longer answering their phones and sending my calls straight to voicemail. Avoid at all costs!!

Great guys, great service. Went above and beyond repairs to help fix items at no extra charge. Even…read morepurchased a new hose for me!
