"I really liked CT Basement systems. The sales rep walked me through the process of the basement SaniDry I had installed. When the installer came it turned out that I didn’t need all of the duct work and I was able to save a few hundred bucks. The installer was very professional, neat and helpful . I definitely will hire this company again. Customer service even followed up with me a few days later and had to remind me to register the system (good thing because I had forgotten)."

"Alex was amazing!! We had a crack in our foundation that another company attempted to repair numerous times. We were fortunate enough to hear about ProSeal and I am happy to report not only did Alex repair the crack to near perfection but the work was done timely, neatly and his customer service skills are top notch. I would HIGHLY recommend ProSeal for all of your foundation needs."

"AFFORDABLE BASEMENT WATERPROOFING WITH A LIFETIME GUARANTEE! My basement walls had 3 cracks in them. They leaked water into the basement when we had heavy rains. To fix these cracks I called in top rated waterproofing companies for their estimates to do their repair work. I found these companies to be very expensive and give minimum time on their warranty's for their work, for the money you have to pay them! Then I found New York Waterproofing Inc. and owner George Carpozi III, George has been in the basement waterproofing business for many years and knows how to fix any type of basement water problem. He has waterproofed residential as well as commercial basements, fresh and ocean salt water problems, leaking basement walls, windows, joints, and water coming up through the basement floor. George can stop the leaks! He has his own system to do this without digging up outside your property! He is so sure he can fix your leak George gives a WRITTEN LIFETIME GUARANTEE on the work he has done for you. Who else does that? I hired George to repair my basement cracks, George and his crew came to my home the Sunday before the NY area had days of RECORD RAINFALLS last week. With all the rain we had, none of the cracks George repaired leaked! The pice I paid New York Waterproofing Inc, and with a written lifetime guarantee on the repairs they made, was about HALF the cost of the lowest estimate I received from the other waterproofing companies I called in! If you have any type of basement water problem, my recommendation is to call and get estimates, but DO NOT SIGN anything, until you call George Carpozi III, and New York Waterproofing Inc. You owe it to yourself, and your pocket! I don't know of any other basement waterproofing company who will give you a written lifetime guarantee on their work. I wish all with wet basements the best, and a happy dry basement to come as well, now go make that call!"

"I called John and left a voicemail and he got back to me immediately. He double checked that I needed a cesspool certification and not an inspection which would have been more invasive and costly, and once confirmed, scheduled them to come out that weekend. The man who performed the certification was right on time and was very quick but professional and thorough. Everything was seamless, and for something requested by the bank so last minute, we were grateful to get it completed so quickly."

"We had cracks in the dyed mortar of the bricks above our garage. Grady took the time to match the color, even with the color having aged 10 years, and you would not even be able to tell that there was new mortar. If your project is anything like ours, you will not be disappointed."

"The masons from this service did an incredible job repairing our crumbling brickwork. They seamlessly matched the existing mortar, leaving no trace of the damage. Professional, efficient, and reasonably priced. I'm extremely pleased!"

"I called a couple of Waterproofing companies for an estimate to fix a basement water intrusion problem. George from AM Shield came over and gave us recommendations for a solution and we chose to go with an exterior foundation repair. The crew that came to do the job were on time and very professional. It took them 3 days to complete the entire job, less time than they had estimated. After the job was completed, they cleaned up the area and put everything back in its place. It has now rained twice since the job was completed and the area that was always flooded is completely dry. I would not hesitate to recommend AM Shield to anyone who has a basement flooding problem."

"LI Waterproofing had done extensive work in my basement for the previous owner, so I opted to give them a try myself to resolve new problems that had not been previously addressed. John and his men were responsive and professional.  The work was done as expected and in a reasonable amount of time.  The price was right for the scope of the work requested.  Hand digging was required to expose the foundation outside.  I opted to remove the plants in my garden bed myself before the work was done.  I'm glad I did so. The men worked around the one larger hydrangea I did not move, and it was pretty roughed up during the process.  (I cut back the broken branches that were covered with tar, and I think it will be OK.)  We have had one good rain since the work was done, and the repaired areas in the basement show no signs of dampness.  So I am hopeful.  My sole criticism of the work is that clean-up could have been done better.  Gravel used to fill the window well was spilled into the adjacent garden bed on top of plants.  I spent about 2 hours sorting that out and sweeping the porch and basement where dirt and cement were left.
