DMV Kitchen and Bath Inc is a family owned and operated Full Service General Contractor specializing in Kitchen & Bathroom Remodeling and Design/Build Services. We ensure a high quality finished product with flexible and attentive service at a competitive price. We pride ourselves on having the ability to make our clients visions come to life with great design ideas and execution. Showrooms: Chantilly, (VA) (703) 657-0997 and Gaithersburg, (MD)
"DMV were the contractors for a series of renovation projects in my home -- renovate a powder room, complete renovation of the kitchen, renovate a closet space, install a skylight, repaint several rooms and the staircase, and refinish the floors upstairs. Javier and the crew were outstanding: very communicative throughout the project, attentive to my concerns and the integrity of the house, and very accommodating with my neighbors. Javier offered many helpful suggestions for tiling, fixtures, and colors. I'm thrilled with the results -- the quality and precision of the work is excellent, and the skylight has transformed my home and my life. Perhaps the most amazing aspect of the project is that I could not be on site as I was posted overseas during the work. I had to trust Javier and his team completely to carry out the work without my hands-on presence. My trust was well-placed. They took care of my home and its contents, and the project was finished in budget and early. Javier was also super-responsive and helpful once I was able to return home. I can't recommend DMV highly enough! S. Boswell"

Len The Plumber, LLC. is a leading plumbing and drain company serving Central Maryland. Our certified professional plumbers are available same day to assist residential customers in Anne Arundel County, Baltimore City, Baltimore County, Carroll County, Cecil County, Harford County, and Howard County. Our knowledgeable plumbers have years of experience dealing with a wide variety of plumbing issues including plumbing repairs, drain cleaning, water heaters, well systems, heating systems, sewer, water, and gas lines. We’re open 7 days a week with no extra charge on evenings or weekends!
"Our first encounter with Len the Plumber for gas boiler repairs went well and lead us to purchase a service contract with them for the 15% discount. However once we needed actual plumbing services and after they provided their "free" HVAC annual inspection it all went downhill rapidly. As others have noted the %15 discount is a concept they don't really honor. We were charged $1100 for less than 30 minutes of work for a repair that only required one cut and a simple joint (We had already removed the drywall and trim for access) and about $30 in parts (which by the way good luck getting an itemized bill from these people). On the HVAC side they broke what was a perfectly functioning 4 yr old AC HVAC and then wanted to charge $1200 to figure out how they broke it plus whatever parts they dreamed up needed replacing. They tried to claim the capacitor was bad. BTW - they brute force discharge the capacitors on units as part of their "maintenance check", something they should never do. We had BGE come out since their info was on the installation tag on the air handler and they diagnosed the issue in less than 30 minutes finding the thermostat had been burned up by mis-handling by the Len tech. They also said they never brutalize the capacitors the ways these guys do unless there is already a suspected issue with it. That's because the capacitor could be damaged by the way they handle it at Len the Plumber. So the "free" annual HVAC check cost me 3 days of discomfort and $250. Len refuses to admit wrong doing and will not reimburse us. They got $5000 in fees from us in less than a year so they don't care if we leave because they know another sucker is just around the corner waiting to be taken. These guys should lose their license given their business practices. Stay away from them at all costs."
