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.

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.

I'm leaving this review to share a balanced but honest account of my experience. While the end…read moreresult of the project was acceptable, the process was far more complicated and frustrating than it needed to be. The sales interaction set the tone with high‑pressure tactics, including statements like "this price is only available today." We moved forward anyway because we knew we wanted the work done. When I later asked to adjust the scope, the salesperson resisted for nearly ten minutes before agreeing to send a revised contract. The first crew delivered solid work on the drain line and concrete, but the vapor barrier installation was sloppy--uneven trimming, gaps, and inconsistent application. They also removed a board supporting the incoming water line without explanation, leaving it hanging from a wire and damaging the clamp. Their initial attempt to "fix" it involved taping the board to a pipe, which was not a proper or safe solution. The sump pump outlet was also installed in a way that caused the discharge pipe to partially block it, putting pressure on the plug. Communication was another major issue. I was never given a dedicated point of contact. I had to reach out to the salesperson again just to report problems. He forwarded my concerns to the office, and I was eventually contacted by Christal. She was professional and genuinely helpful, but her phone number repeatedly showed as disconnected, and only some text messages went through. I had to call the main line each time and ask to be routed to her. A week later, two crews returned and corrected the vapor barrier, repaired the board, and moved the outlet so it was no longer obstructed. The final work met expectations, but the overall experience involved unnecessary sales pressure, communication challenges, and multiple days off work for corrections and inspections.

My experience with JES Repair was frustrating and ultimately disappointing…read more The project itself was completed on schedule, but the quality and planning of the work left a lot to be desired. The beam repairs appear to have been completed in the easiest way possible, with little consideration for the work that would need to happen afterward. The crew cut the subfloor approximately three inches away from the walls and left it unsupported. As a result, my flooring contractor had to tear out two sections of flooring and replace the entire subfloor in those areas because the necessary repairs were never addressed during the original project. Even more frustrating, JES only opened a limited section of the floor instead of exposing the entire affected area. Once the flooring contractor had everything opened up, additional damaged wood was discovered that now requires even more repairs. Since JES was already working in that area, it is difficult to understand how these issues weren't identified or why the floor wasn't opened far enough to properly inspect the entire section. Addressing everything while the area was already exposed would have saved significant time, cost, and disruption. The inspection process was another major disappointment. The county inspection failed and was rescheduled without anyone from JES informing me ahead of time. I was then told that no one from JES would attend the reinspection and that it was between me and the county. As a homeowner, I'm not a contractor and shouldn't be expected to answer technical questions or represent the company's work to the building inspector. I hired JES expecting professional workmanship, thorough planning, and support through the entire process. Instead, I've been left coordinating additional repairs, paying for work that could have been avoided, and handling inspection issues that should have been managed by the contractor. Based on my experience, I cannot recommend JES Repair. UPDATE (07/08/2026): I connected with the resolution team and are working through the issues in a positive and constructive manner.
