When I called them they moved me up to an emergency appointment to fix my issue. They came on a Sunday when it was raining and dug up and installed water pipes to drain rainwater away from my basement. It was a massive undertaking and I'm glad that I got a quote from Virginia Drainage and Erosion. I would definitely recommend them to at least come and give you a quote. The pricing is reasonable for my project.

The whole team at Basement Masters did a great job on two projects to waterproof our basement and…read moreboth turned out great! The first one was a major project where they had to dig to the foundation and waterproof the whole side along with installing a sump pump. They knocked it out with ease and they beat the national chain's pricing by a wide margin. The second job wasnt that small of an issue but they still completed it in one day. Highly recommend Basement Masters!

System has lifetime warranty, but the company who installed it many years ago suggested I have a plumber and a foundation specialist check it out before they come. If not there their issue under the warranty, there's a hefty charge. I contacted Randall, the owner of Basement Masters, who came out promptly, looked at old system, discussed concerns with warranty coverage I might encounter, and found no foundation cracks. He kindly offered to have me call him after the old company comes out to assess the issue. All done for no charge. You'll not do business with a more honest, reliable company. I highly recommend Basement Masters and Randall ,

This review is for installation of a replacement french drain and sump pump in a basement in NW DC…read more I really did my due diligence researching and contacting companies. I had five companies out to my property and felt that Ernest was the best value. He provided high end components such as the Miradrain, but charged a very fair price. His company was incredibly responsive, even responding to my 9pm texts and emails within the hour. He was incredibly friendly to work with and I really liked that it is a family owned business. Also, I was out of town during the installation, but he was incredibly wonderful about taking lots of pictures and documenting the different stages. My general contractor was at the house working on another project and said Ernesto's work was excellent and he went above and beyond. He also had great ideas about how to hide the discharge pipe and make the property look as nice as possible. His work also comes with a lifetime warranty. Ernesto was also able to squeeze my work in the week I needed. I explained that I had a tenant in a hotel costing me money each day and he made it work in his schedule. I would 100% recommend this guy!

Ernest was recommended by a friend and we could not be more pleased. He and his friendly crew dug a…read moretrench next to the basement wall, installed drain pipe, gravel, and a sump pump. They patched two cracks and noticed that an existing downspout should be extended. They installed a drain in the window well also. The estimate was quite accurate; the final price was higher because of the newly-discovered cracks that needed to be repaired. In any event, the cost was extremely reasonable; we had been quoted twice the price by another company. The dust was minimal, Ernest was very open and communicative and they cleaned up the mess very nicely. I highly recommend Ernest Waterproofing; you can't go wrong!

We have been in communication with VM Drainage and Erosion Solutions since March 12, 2026 regarding…read moreproblems with two projects which they completed on our home. In 2021 they completed a waterproofing project which carries a 12 year warranty, and in 2022 they completed a patio installation which carries a 5 year warranty. As of April 22, 2026, VM Drainage and Erosion Solutions has not provided a solution to either of these problems. Our foundation wall was bowed before VM Drainage and Erosion Solutions excavated and waterproofed our home in 2021. We showed the bowed wall to VM Drainage and Erosion Solutions before the excavation began, and they recommended proceeding with the project without reinforcing the wall. We began to see small cracks in the foundation wall shortly after VM Drainage and Erosion Solutions completed the waterproofing. We showed the cracked wall to VM Drainage and Erosion Solutions before they installed our patio in 2022. VM Drainage and Erosion Solutions assured us that the cracks were not a problem. However, the cracks have grown substantially since then, and an independent structural engineer has confirmed that the wall is failing. In addition, the patio is sinking, the exterior waterproofing membrane is slipping, and there is a damp smell in our home near the cracked wall. In order to provide access to the cracked foundation wall for repairs, our patio will have to be removed, and the exterior of our home will have to be excavated again. Once the engineer's recommended repairs have been completed, the wall will have to be waterproofed again, and our yard will have to be regraded again. Finally, our patio will have to be reinstalled. We paid VM Drainage and Erosion Solutions to do all of this work in 2021 and 2022 because we trusted their professional opinion about our foundation wall. We now have to pay another contractor to do all of this work again so that our foundation wall can be reinforced. VM Drainage and Erosion Solutions has stated that they will not honor the warranty on the waterproofing project because the man who estimated the project is no longer employed by VM Drainage and Erosion Solutions. They have not provided details about how they will honor the warranty on the patio installation. We will update our review if VM Drainage and Erosion Solutions honors the warranties on their work. In the meantime, we cannot recommend VM Drainage and Erosion Solutions.

We had drainage and hardscaping done by VM. The drainage part came out great and we're very happy…read morewith it. But the hardscaping is really bad and I would recommend you avoid this company if you want a flagstone patio. The installation team generated huge clouds of dust all day long because they didn't have a wet saw. It covered my side yard as well as my neighbors'. They also didn't wear any PPE, which is unsafe and unprofessional. The patio is graded correctly and has helped with water management issues, but they installed a dozen stones that were clearly damaged with large scratches and gouges. I called the project manager out and they replaced ten of the most damaged stones, but honestly they should not have taken delivery of this product and they should not have installed it. They should have sent it back to their supplier to get it swapped out. The mortar work is also very messy and overall makes the patio look bad. The mortar comes up over the edges of the stones and there are drips and smears to this day. I hope the weather would even it out over time but now a couple months later, it still looks really bad. We have neighbors who just got a new flagstone patio done by another company and the difference is stark. Their stones are perfect and the mortar has clean lines and looks great. Nice people and to their credit, they did come back after the initial install and put significant effort into improving it. But for the money, it's still not a good value.

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.

We first used DD 22 years ago to waterproof our basement. Recently we noticed some mold. We called…read morethem to come out and take a look, as there is a lifetime warranty their work. Antonio found that one of our sump pumps was broken, resulting in some moisture build up, and the associated mold. All that needed to be done was some minor mold remediation and replacement of the pump. Contrast that with two other estimates we had obtained (before we remembered the warranty) that didn't find the faulty sump pump, and wanted to replace drains and do major mold remediation for thousands more dollars, rather than just treating the moldy area. To top that off, I called on a Friday, they were able to come by and assess the situation the same day, and do the work the following Monday! No waiting!

Their team is consistently professional, responsive, and a pleasure to work with. Most recently, we needed their help to repair a support post under our outdoor deck that had begun to rot due to poor drainage. They not only fixed the structural issue quickly and thoroughly, but also installed a proper drain to prevent the problem from happening again. Their pricing has always been very reasonable, especially considering the quality of their work and the speed of their response. It's rare to find a company you can trust repeatedly, but they've earned that trust every single time. Highly recommend.
