Triad Basement Waterproofing recently installed a Basement Relief System to address water pressure and flooding beneath my basement floor and behind walls during heavy rains. 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! read more

I had a sump pump replaced along with moving gutters away from my home. I can't recommend this company enough for basement waterproofing.

We hired Triad to install a sump pump for our basement stairwell. Mike and his team were a pleasure to work with, and the work itself was neatly done. We encountered only one hiccup during the job -- the crew accidentally left our basement freezer unplugged before leaving, ruining a lot of our groceries. But Mike was incredibly gracious when we reached out to him, responding to us on a weekend morning with a generous offer to make it right. We really appreciated his willingness to take responsibility and to stand behind his work. If we ever need waterproofing help again, we won't hesitate to call Triad. read more

I recently had basement water issues and did very detailed research to try and find the best company. I ended up using Triad Basement 301-532-7903. I got a near perfect job. Mike- the owner is very honest and thorough and lets you know exactly what you need done. He met with me on two separate occasions as I had more questions that I needed answered. He is very accommodating and sent out guys who truly worked hard. Santiago- was fabulous and treated it like it was his own job, also Wilpredo, Nuam, Marcelino, Andress, Matthew and Justin. We're all amazing. read more

I had a very positive experience with this company. I was having a bizarre problem with water coming out the baseboard of the garage that had the first plumber I called stumped. He suggested I call a waterproofing company, and Triad actually does above-ground work, which many of these companies do not. The owner came out the next day and was very professional. He decided to send out his own plumber to find out exactly what the problem was. The plumber then spent hours methodically pinning down the issue, which he then fixed (turns out a random pipe that was in a place a pipe should not be was leaking). It turned out I didn't need a pump or drain at all, likely saving me a lot of money. Very impressed with their work and definitely recommend. read more

Honest company and inspector , no upselling or push, give honest opinion based on facts

Triad is awesome! Mike, Tracey, and Justin were amazing to work with, and Justin did a fantastic job in addressing our foundation cracks and water leaks. Not only did he address the initial crack and water leak beautifully, but he also identified two other foundation cracks with active water leaks that needed to be addressed and we otherwise would have missed. He was very courteous and provided great customer service including explaining and showcasing in-depth the remediation strategy, taking the time to answer my questions, and leaving the place cleaner than he found it. It's such a relief knowing that the three cracks/water leaks are sound. I can't recommend Triad enough. read more

We love Justin and are so impressed with the work he did on our home! The underground drainage pipe from a gutter was clogged, causing water to back up and flow into the basement window well, causing a steady flood into our basement every time we got significant rain. We actually didn't even get estimates from anyone else after he came to look at out problem - the price seemed totally reasonable, Justin was super nice and took the time to fully explain what was going on, and they were able to schedule relatively quickly during August, when lots of people were needing their services. Turned out the pipe from the window well into the sump pump system was also clogged; Triad replaced this pipe, as well as two underground drainage pipes from gutters, and the exit pipe from the sump pump system. After seeing how much work he did (by himself in the middle of August!) I almost think they undercharged us. He got it fixed for us right before Tropical Storm Ida swept through the area, and our basement remained dry (and has ever since). The work also looks great. Would absolutely use them again. read more

My newly acquired 10 year old house had a leaky basement. I hired Triad to install a sump pump which required jack hammering a hole in the basement floor, creating a drainage channel, installing a sump basin, and installing an electric pump. They completed the work 1.5 days, were prompt, always courteous, and left my house perfectly clean and restored to its previous condition. Prior to finding Triad I had met with two other vendors who clearly didn't know what they were doing. In one case the guy didn't show-up twice for the appointment to give me an estimate. Mike D is a real pro, and if you want it done right I suggest using Triad. read more

Triad Basement Waterproofing - Newly installed sump and sump pump by Triad - Waterproofing Near Me - Frederick, Maryland

I can't say enough about Mike from Triad. We hired him after this company installed sump pumps for our neighbors, and they were very happy with the results. Our project was a little more complicated, and involved working alongside another contractor. Mike was super professional about it, while the other contractor was unreliable about timelines, and would contradict their own plans from one day to the next. Mike was super patient, worked around the other contractor's unreasonable schedule, and was fair about pricing when the other contractor's actions caused his costs to increase. I'd definitely recommend him to anyone. read more

A year ago (August 2018) we had a major flood in our basement after a huge rain. We selected Triad to waterproof the basement. Today )July 8, 2019) we had the biggest rain in decades. Streams flooded, cars washed away, water rescues But OUR BASEMENT IS DRY. Thanks to Triad. Great job! read more

I heartily recommend this company. They are competent, responsive, and pleasant to work with. I wanted to upgrade my sump pump. I found Triad by searching online and reading customer reviews. It was obvious from that search that Triad was the company I wanted to work with. I scheduled a review visit with Mike, the owner. He is TERRIFIC. He knows his stuff, he tells it like it is, is polite, and he does what he says he is going to do. The installation of the new sump pump went great. They arrived at the scheduled time, were very clean, did a great job, and there was no mess afterwards. Every interaction with this company was absolutely first class. Again, I heartily recommend them. read more

This company came recommended by two friends who had a "good experience,"and the other who said "they were beyond awesome." It took 3 months just to get an estimate (like a good carpenter/tattoo artist, I take this as a very good thing). Unlike the other two estimates, they were not interested in just throwing a sump pump into the ground (literally what the other companies wanted to do). They explained the importance for a proper drainage system (removal of dirt, old concrete pad, new gravel, drain, tub, sump pump and properly angled concrete pad) needed to be done to support a sump pump. They were here at 8 am, completed the work and done within the time indicated on the estimate. Four neighbors who have similar issues saw the work and are now on their waitlist for estimates. Well worth the wait! read more

Triad Basement Waterproofing - Waterproofing Near Me - Frederick, Maryland

It's stressful to find water in your home's basement a month after purchase but thanks to the team at Triad we can now enjoy a dry basement. Because of all of the stellar reviews we contacted Mike, the owner, for help as soon as we saw water coming in after a heavy rain. Mike was patient explaining the process they use and letting us know that the work was guaranteed. Justin came out promptly to repair the leaks. He was so professional and friendly but more importantly he put us at ease explaining everything he was doing. If you ever need basement waterproofing Triad should be your first call; you won't regret it! read more

We called Triad and a few other companies to give us estimates on diagnosing and fixing a worsening basement leak. Even though we called during the height of the bad August 2017 rains we had in Maryland, Mike, Triad's estimator (and I believe co-owner), was able to come out to our place within 3 days, fitting flexibly to my work schedule. Even better, Mike gave a quick overview of the likely problems, a clear rundown of the possible solutions and ranges of costs, and rundown of the steps Triad would take to confirm the diagnosis and proceed with the solution. Unlike other companies' estimators, he didn't rush immediately to an expensive basement wide sump pump system, noting the likelihood a simpler crack seal would probably solve the problem. Triad's contractor was back within 3 days to confirm the problem and place the seal. In the latest rain we've had, our basement is bone dry. Very pleased with the professionalism, responsiveness, and clear expertise of the company. read more

Mike is one of 3 vendors we contacted to obtain an estimate and recommendation on how to handle the water that was pouring into our basement every time it rained. Mike is the only one who suggested waterproofing from the outside (we live in a townhouse). Bobalu arrived and was super friendly and he worked the entire day in blazing heat alone! Day 2 came and this time he had another person helping him. They both were so friendly, explained everything to us and even dealt with an asshole neighbor of ours. The first day of the project ended in torrential rain and we watched with baited breath how well the partially completed French drain worked. What a relief! I highly recommend Triad, you'll get honest advice, a fair price and a friendly team! read more

This is by far the worst company I ever dealt with. The workers were late, extremely rude, and messy. The work was of terribly poor quality. For example, they found and used our extension cord, without asking any questions. It is now a part of the wall. Then, they charged us a $50 fee for moving furniture! To finish up, they told the maintenance company that the water source was probably the company's workers tracking in snow. The workers did track in snow. However, this can't possibly the reason why we called a waterproofing company in the first place, can it, genius? read more

I needed a French drain and sump pump. They gave me an estimate and a date, and then they showed up on that date, did the work, and met the estimate. After, I had some questions (not about the quality of the work, which was as expected) and they were very responsive. I chose them because of their previous reviews. I am glad to be able to add one more. read more

I just had the pleasure of working with Pete from Triad Basement Waterproofing. I typically don't write reviews but I had such a positive experiance with this company and Pete that I had to "vent" about it. It was nice to see that rather then just showing up early he took the time to call and make sure it would be ok if he arrived 15mins or so before schedule. The thing that impressed me the most was his honosty, I had another waterproofing company come over the prior day and they tried to pitch me a almost 6000 sump pump system, but Pete flatly told me you don't need any work done but if you still want stuff done I can do it for you but I can't tell you that you need anything. The honosy and candor is hard to find in home services these days. Keep up the good work Pete/Triad Basement Waterproofing.! read more

I just had Triad complete a job putting in a sump pump and drain tile along one wall of my cellar. I believe the owner was the one who came out to see what I needed to have done and wrote the initial estimate. I was happy to see that his price was in line with what I thought a "good deal" would be for the project. (I'd had some similar work done before in a previous house, and I got a number of quotes back then before going with a small company who had the best price. Triad's price looked really comparable to that offer.) By contrast? I got one other quote from a competitor for this project who was around 2x Triad's price. They were able to get started in about 3-4 weeks after giving me the quote, and an electrician showed up earlier to get an outlet installed for the sump pump to plug in to. The rest of the work was completed in less than a day, and appeared to be of good quality. The only issue I had was that we initially discussed a few details of how I wanted the installation to be done which he neglected to write down on the work order/invoice. So when the crew came to do the job, they weren't aware that we had discussed those items. I wound up having to call Triad back and have them re-schedule to come back out and make those corrections. To their credit though, they did all of that work as originally promised. (I wanted the discharge line to be buried under my sidewalk so it could come out in a "hidden" place behind a row of bushes. Initially, they failed to do that. And there was a "speed drain" we discussed installing at the base of my cellar steps, so water collecting there would go straight into the sump pump.) Ultimately though? They gave me exactly what I asked for, and the system has been keeping all the water from today's rain out of the cellar! (Just as a general comment.... I noticed another reviewer complained about how messy the work was. My experience with these sump pump and interior drain installs is, they're ALWAYS messy. You have to budget to have someone come out after it's finished and put back things like drywall and the bottom part of the wood framing behind it, if you had a finished basement before they started. I had to replace cedar boards in a cedar closet too, in my case, because we decided to put the sump pump in the closet floor to hide it. They couldn't connect it up without ripping a couple of holes in the closet itself. It's just the nature of this type of project.) read more

This company has it all. The sales rep was very good, finding out what I needed and quoting on that, not whole house ventilation upgrades like some other companies Their workmen were technically expert, courteous, and careful with my property. They did a great job. They also showed a serious commitment to customer service, honesty and complete trustworthiness. They saved my house from collapsing, my water problems were so serious. In the middle of the job, we discovered that a third basement wall had problems that could not be seen while our built in shelving was still in place. They had me over a barrel and could have really stuck me with some huge charge. Instead they gave me a fair price for the additional work. Five years later, my basement is still dry and I am very grateful to them. I cannot recommend them highly enough. read more

James from Triad was a God's send. He was sympathetic and to the point on what needed to get done with the basement. I had to get a water treatment system installed in my house and the team work quickly and timely to prevent further damage from the water infiltration (during the crazy Hurricane Irene followed by 6 days of straight rain). The team was professional and got done when they said they would in 1 day. I would recommend Triad for any homeowner that is need of waterproofing for their home! read more

Mike and the Triad team were excellent to work with! We had a bit of an emergency in our basement, and they were able to come out right away and give us an estimate. They then scheduled us for the following week and got the work done within the time frame that they said. The work area was left clean, and they were able to work around my husband's and my busy schedules. I highly recommend them for any waterproofing needs! read more

I can't say enough good things about this company and its people. They are the best! I bought an older home that had incredible water issues in the basement. With just the slightest amount of rain, I would come home from work and have to bail out the basement. Just one trip from Triad and my troubles are over. With all the snow and rain we've been experiencing, I never worry about the basement anymore. It is bone dry no matter what the weather. The workers not only did a fabulous job, but they were quick and clean and left no mess in their wake. Plus the work is guaranteed for the life of the house. No matter who owns it! I would highly recommend this company to anyone who needs excellent waterproofing. Triad Delivers!! read more

Like one of the other reviewers, I called and asked to have someone come out for an estiamte. They told me when they could make it and I confirmed the date and time with them. I burned a day's worth of vacation to accomodate the appointment and they never showed up, nor did they ever call to explain why ro to let me know they were going to flake. Also frustrating is that when they call you back, if you return their call to the number shown on caller ID, it is an answering service whose only job it is to take your name and number. They can't tell you who at the company called or why thery were calling. Horrible way to do business, but I guess if these reviews persist, they will be doing less and less business overall. read more

We had a wonderful experience working with Mike and his Triad team! After meeting with several different companies, we were impressed by Mike's superior knowledge, experience, and professional demeanor - it was hardly a competition. Mike came to our home not once, but twice, to help pinpoint how water was entering our basement. He also gave ideas for information-gathering water tests to complete on our own before work would begin. We ended up doing a fairly extensive project with Triad, which included new interior drains around the perimeter of our basement, backyard regrading, and various smaller things. The work was done professionally and on-time, with above-and-beyond communication directly with Mike throughout. We feel secure knowing that we have a life-time guarantee with Triad for this work. With an old house with many projects, it meant a lot to trust that we were in capable, professional, and honest hands with Mike and his Triad team. Highly recommend! read more

Triad installed an interior french drain in our townhouse basement and I am extremely pleased with the work that they did. Their pricing was very reasonable and the crew was very efficient. They explained everything they were doing and after it was done walked me through everything the did. The crew did a great job to keep the dust down and cleaned everything up when they left, even wiping down the hardwood floors that they had protected with a tarp but a little dirt got on the floor. Highly recommend this company. read more

Just wanted to give a shout out to Triad, they have been very responsive as we continue to try and work through some problems. Always return calls promptly, Pete gave a thorough explanation of the work that he felt we needed to have done, received the contract in a timely fashion. Unfortunately we have continued to have some problems even after the work is done but it's been things that aren't necessarily within the confines of their work, yet they have twice (including yesterday during the pouring rain in an effort to actually see the water seeping in!, driving down to Alexandria the same day I called) come down to see what's going on and try to get to the bottom of it. Have assured me that they will do whatever it takes to get it fixed, have never tried to hit me up for any more $$. Very nice guys, clean up the work site. Not getting 5 stars because we are still having some issues but as said, I am confident we will get them resolved ASAP! read more
