All issues identified in my previous review, and more, were satisfactorily resolved
Peter T.

Update on my previous review: Evan reached out immediately to let me know that the sprinkler had actually been fixed behind the scenes- which I quickly confirmed to be the case, leaving me a bit embarrassed. In response to some of the photos, Evan also personally came out to inspect the work, and recommended a few improvements including adding sod and re-doing the pop-up top area. The follow-up work was completed promptly and went well beyond my initial ask of fixing the sprinkler head... Evan even threw in some mulch for some of the sad-looking trees. To summarize: 1. Did they solve my drainage issues? Yes 2. Did they do this without introducing new problems? There were a few minor issues, described in my previous review 3. Did they follow up or resolve the problems they introduced? All issues I raised, and some I didn't, were acknowledged and fully fixed to my satisfaction. The sprinkler issue I had not heard back on had actually been fixed by the time I wrote my review (and I just didn't know it) 4. Would I use them again or recommend them to a friend? Unreserved yes (I am having Evan give me an estimate for an egress window this week) 5. For the price, am I happy with their work? 5 out of 5

Evan and his team did an amazing job. I noticed I had water coming into my basement this summer. After conducting a lot of research I contacted Exterior Waterproofing Experts; a division of Clifton Contracting. Evan came out to asses the damage and determine the cause. He thought he found the issue, but did advise he wasn't 100% sure, but wanted to start with the first plan as it was much cheaper and did not want to unnecessarily overdue what would be needed. I appreciated his honesty. Unfortunately, the initial resolution did not correct the problem. After re-contacting Evan we determined a full excavation would be necessary. The project was slated for 2 days and the team was great. They worked diligently on the first day and were having trouble finding the cause of the leak. They refused to leave until they found it and right before it got real dark and after digging probably 12 feet, they found that the entry was at the very bottom of my foundation where it met the ground and poured footing. Even better was that Evan through in additional buried drainage on my neighbors simply because it was in the best interest of our property to keep away further water erosion next to the foundation. This was not part of the original project quote. My neighbor's yard and mine were completely torn up. But I knew that the contract stated they would be everything (plants, shrubs, landscaping, etc.) back as it was before the work so I had my fingers crossed. After the team completely all the necessary restoration work on the second day, their clean up work was immaculate. You could not tell that it looked anything like it did before. The work was extra hard due to heavy clay soil and the depth that it took to find the damage, but the guys were great and got it all completed in the planned 2 days.

These guys were the light at the end of a several year tunnel of our basement stairwell drain getting overwhelmed and flooding in our home. We had rigged a very unsightly tarp/plywood contraption to keep the water our thinking the cost of a permanent solution would be out of reach right now. Wrong! We were so shocked at the fast and affordable estimate we received. Evan assured us they had done dozens of stairwell projects just like ours. He worked quickly to come up with a solution and the price tag was about 1/5 of what we had in our heads for a solution. A few days after the job was done (removed existing drain, installed a basin and 4" pipe running 35 feet graded down to the corner of the property) we had a series of torrential down pours day after day. And the drain held! No water in the basement! I can sleep at night now not worried about our basement flooding and I'm not embarrassed to have neighbors see our stairwell previously covered in a very ugly lean to contraption. Highly recommend Evan and his team.

Drywell Hole Dug

I am thrilled with the job Exterior Waterproofing Experts did! I was required by my city to install a drywell in my front yard. Evan came by and gave a reasonable estimate and promised his team would have my yard looking perfect afterward. The team showed up exactly on time. They were friendly and knew what they were doing. The project went extremely smooth. I was surprised to see when they finished they spread grass in the areas where the yard had been damaged - that was going above and beyond! Overall I was very happy with the entire project and the quality of their work. If I have another drainage project there wouldn't be anyone else I would call.

Evan and his crew came out to even out the grade in our front and back yard. Evan gave me a great price for the work. They removed existing plants, added dirt, fixed the grade, added plants, and added mulch. His crew was on time and hard working. Highly recommend!

See all

Evan and his team did an incredible job fixing a water issue we had for nearly 10 years in our Alexandria Verizon Retail location.

Mike DeGirolamo - the owner - during his assessment provided step-by-step explanation of what needed to be done to address this issue. He was very thorough and clear in his explanations. He did not try to 'upsell' or include items that were not necessary. Prior to work starting a timeline was provided. Timeline detailed team arriving over the course of 3 days and what to expect during this time. The Triad team - Michael, Justin and Roberto - arrived as scheduled on their assigned days. Before starting work for that day they again went over every detail of what they would be doing. Master plumber Justin Dorrier was amazing in his handling of the plumbing side of this process. His attention to detail and explanations clearly showed his professionalism and knowledge as a master plumber. I did much research and obtained multiple estimates from about 5-6 different waterproofing companies before selecting Triad. Triad was by far the company I was most impressed with. I highly recoommend Triad Basement and Waterproofing if you have any waterproofing needs. They are all (Mike, Tracey, Michael, Justin and Roberto) true professionals at what they do and were a pleasure to work with --- I wish I could give them 10 stars! Thank-you Triad Team!

The initial sales person was a classic over-seller and promised the world while simultaneously doing a very surface-level review of the situation, ultimately concluding that we were in need of an indoor water mitigation system and sump pump. The sales process was tortured, over-the-top, and ended with the classic "same-day-only discount" proposal (red flag number 1). The scheduling process and lead-up to the project was radio-silent with no preparation on what to do or what to expect from the project manager or the sales person until I reached out proactively. I had to call the morning the project was set to begin to even know if they were coming or not (red flag number 2). The project itself eventually began and within less than an hour it became obvious the source of the leak was in fact a burst pipe and not ground water coming in through the basement. I called the office and put a stop order on the work at which point they immediately became very cagey about what options were available to me and from this point on once again went radio silent (red flag number 3). Upon reaching out to the office multiple times (via both email and phone) to address the issue and seek at least a partial refund of our deposit for the issue, they took 3+ days to even respond, and when they did, claimed that despite obvious pictures pointing to the pipe being the issue, it could have been ground water at the same time and they were unable to provide any refund of any kind (red flag number 4). I get that I signed a contract. I get that they planned and scheduled the work. I also now have learned an expensive lesson about trusting my gut and being more proactive about my concerns. But they're supposed to be the experts! And the fact that they took absolutely no responsibility for having done a poor assessment of the situation up-front and then pretended like they were actually still right about it was disappointing and embarrassing. I can't in good faith recommend working with this company to anyone.

My sump pump discharged a significant amount of water, which created ice on the street during the winter and damaged my lawn. I also asked them to address a small uneven area around my sprinkler system. The team explained that they would regrade the area, use my existing soil, and plant grass seed, which I was completely comfortable with. They completed the entire project in just one day. At the end of the day, they sent photos of the finished work to the owner. Although I thought everything looked great, the owner wasn't satisfied with the appearance of the hay covering the newly seeded area. Even though installing sod was outside the original scope of work and would have been a much more expensive solution, he decided to go above and beyond. The very next day, he sent his crew back with fresh topsoil and sod at no additional cost. They added topsoil around my home to improve the grading and ensure water would drain away from the foundation. They even moved my stacked firewood, added topsoil underneath it, and carefully put everything back in place. When they finished, they watered all of the new sod, adjusted my sprinkler heads to ensure proper coverage, and thoroughly cleaned up the work area. My yard honestly looks better now than it did before they started. Premium Drainage was not the cheapest quote I received, but they were also not the most expensive. What set them apart was their professionalism, attention to detail, and commitment to doing the job right. I would absolutely recommend this company to anyone looking for drainage work or landscaping improvements.

After watching it perform flawlessly, I can say without hesitation that Premium Drainage and Erosion Solutions is the best of the best. I have never worked with a company as responsive, professional, and committed to excellence as Adrian and his team. They went above and beyond to ensure that the system they installed would withstand the worst weather our area could deliver -- and it has. When I first moved into this home a year ago, even a light rain left puddles across the yard. That problem is completely gone. Their responsiveness was exceptional. When I needed documentation for my HOA, Adrian's team provided it immediately. They completed the work faster than originally estimated, and every interaction was marked by professionalism, clear communication, and genuine care for the quality of their work. The value of what they delivered went well beyond the price they quoted -- exceptional service at an exceptional value. In short, I cannot recommend Premium Drainage and Erosion Solutions strongly enough. Their workmanship is outstanding, their standards are high, and their team is exceptional. They delivered exactly what they promised -- and more.
