"Excellent service. The technician (I am blanking on his name) was very professional. He looked at the issue (clogged drain), gave me a couple of options, we chose one, he proceeded with unclogging the drain and voila, no more issue. Thank you!"

"Very kind and competent. Happy to give my money to a family business instead of one of the plumbing giants. As far as pricing, I had a utility sink faucet and drain replaced, and two shut-off valves and a hose bib installed, and was charged $2,500."

"My experience with this company was great. I was able to tell them my issues and they gave me several options. Ultimately we went for the full French Drain system. Everything was done on time and the estimates were very fair. Warranty on the work is great. I would call them again if needed."

""After 15 years of enduring water and flooding damage to our yard and the foundation of our house, and after trying various 'solutions' from well-intentioned landscapers that never truly resolved the issues, we ultimately decided to engage Drainage and Erosion Solutions. We required comprehensive flood control and damage mitigation, and their expert team skillfully implemented swales, dry creeks, catch basins, and channel drains in areas where water management was critical. They also replaced a water-damaged window well, removed a flagstone patio to install drain basins and drainage pipes, and flawlessly reinstalled it. The supervisor and crew displayed remarkable knowledge, professionalism, and an unwavering commitment to detail throughout the entire project. This system has been operational for several months now, and even during the most intense rainfall, which historically led to road flooding, my house and foundation remain dry. We enthusiastically endorse this company without reservation.""

"Extremely excellent.. The service was good since 2008. They did excellent work. They repair the problem issue by installing a inside french drain and a sump pump. Which correct the problem at the time. The costing was reasonable and except able. And in addition to that courtesy and professional. And very clean after finishing work."

"A superior company. They follow through on their commitments. They have long time employees with great experience. BWN waterproofed our leaky basement about 10 years ago. No problems for almost a decade. After a recent weekend downpour we had water along one of the basement western storm-facing walls. We called and opened a service ticket with Gary. They called back in a little over a day and scheduled a repair at our convenience. Joe, a long time employee, very courteous, professional, and respectful, arrived on the job. He had reviewed our prior project and knew the property well. And it was a window well drain that had clogged. Luckily, it was easily unclogged and the problem was completely solved. We have always been pleased with the work and response of this locally owned business."

"Went very well. Complete in 2 full days with a 2-person crew. They paid particular attention to aesthetics afterward which I appreciated. Most positive part was, they finished the day before a torrential rain storm which washed away much of the disturbed soil (where the drainage pipe was buried) as well as mulch and some river stones. I informed them and, without my realizing, they returned to my property, cleaned everything up and left quietly. When you do jobs like this, things can go wrong (including the uncontrollable, like inclement weather). What I appreciated was how responsive they were and how they ultimately made it clear that they wanted to do a good job for their customer. Lily, the project manager was great. The crew did a good job. The price was at par with other places but I'll take that + great communication and responsiveness any day. I've already referred them to 3 others in my neighborhood and I will definitely use again."

"I’m back again to write another stellar review for GAC. Last year they replaced our HVAC system; this year we circled back and had them install a home generator. This was a long and drawn out process due to the various approvals needed from Montgomery County as well as coordination with Washington Gas (which ended up not just being a simple sign off but necessitating an additional, expensive upgrade to the gas line from the street to our home). Nevertheless, GAC did a fantastic job shepherding this process over the 6+ months of waiting on stakeholders, and they were also maximally accommodating to our family’s significant constraints on time and availability (due to health concerns related to a medically fragile family member). A special kudos to Sandy M, GAC’s master electrician, who took it on personally to ensure we were taken care of all throughout this process, going above and beyond with phone calls, text messages, personal visits, etc. on behalf of my family, I want to thank GAC and am giving top marks across the board for this effort which was complex , lengthy, and ultimately successful."
