    Wow! What a great experience with this company. I would highly recommend. From my first call- in,…read moreconsultation with Matt, the company even called to remind me of my installation date, and the crew was very clean and friendly! What a remarkable experience!

    My experience with Fortress Foundation Solutions was extremely disappointing…read more The project that we sought a solution for was sold to me based on Riley Ethier's, their salesman, confident assessment that my sunken concrete slab was the result of ordinary settling. That assessment mattered: both the HOA and I relied on it when negotiating who would bear the cost of the repair. When Fortress's crew actually began the work, however, their foreman encountered heavily saturated soil beneath the slab and could not complete the repair. He subsequently told me in writing that he was "almost 100% certain" the slab had sunk because reconstruction of the adjacent sidewalk had disturbed and weakened the supporting soil. In other words, Fortress's own field foreman materially contradicted the assessment upon which the contract had been based. What followed was just as troubling. I sent Riley a detailed email explaining what had occurred and asking that the work be stopped pending an internal review and an updates solution. He did not respond or even acknowledge my email. Instead, he called the HOA representative privately and left an informal message asking him to call back. Riley responded to me only after I sent a second email establishing a firm deadline. Fortress ultimately agreed to cancel the contract and refunded my deposit in full, which I appreciate. But the experience left me with no confidence in Riley's assessment or professionalism. My advice to anyone considering Fortress: make sure you understand the qualifications of the person diagnosing your problem (beyond that of a mere salesman with absolutely no qualifications ie. engineering or relevant construction, insist that the diagnosis and proposed solution be put in writing, and make certain the proposed repair addresses the underlying cause rather than merely the visible symptom.

    It's easy to give a company a good review right after they finish a job. I think you learn a lot…read moremore about a company when you call them 12 years later with a problem. Triad Basement Waterproofing originally did work at our Gaithersburg home about 12 years ago. Recently, we discovered that the drain from that original system had clogged and our sump pump had also stopped working. I reached out to Triad and was honestly impressed with how quickly they responded. Within about 12 hours I had heard back from them, and Justin was at our house the following day. He replaced the bad sump pump and made sure everything was working properly. He then returned on Monday to replace the clogged drain. Justin was fantastic. What really stood out was his attention to detail. He was extremely thorough, took pride in what he was doing, and cleaned everything up so well that the area was spotless when he left. But the biggest reason I'm writing this review is that Triad stood behind basement waterproofing work they had done more than a decade ago. There was no runaround and no trying to avoid responsibility. They simply took care of the problem. After 12 years, that kind of service says a lot about a company. I wouldn't hesitate to recommend Triad to anyone looking for basement waterproofing or sump pump work in the Gaithersburg area.

    Triad Basement Waterproofing recently installed a Basement Relief System to address water pressure…read moreand 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!
