"Kelvin Funes, owner of KF Remodeling is a very experienced contractor in all aspects of home building and remodeling. They have done four jobs for me this year from Feb to July of 2025. Jobs included; shower/bathroom, plumbing, electrical, drywall, and painting. Some were major plumbing and installation of wired smoke detectors. Not easy but Kelvin always tells me his job is to solve problems. And he does. Twice I needed to call him back to handle small over looked items and he returned promptly to handle them. Kelvin's knowledge, experience, and advice contributed greatly to the success of my projects, I am impressed and well pleased. Thank you KF Remodeling. "

The North Star Companies, LLC, is the premier contracting company in MD. We pride ourselves on delivering a quality service, at an affordable price, with the customer's best interests at heart.

"We have used The North Star Companies for several jobs in the past, with the most recent being the largest. We hired them do a complete renovation of our home in Severn. The job grew larger as demo began and turned into a job requiring the rebuild of exterior walls, demo of concrete slabs - basically the house had to be rebuilt from the ground up. All new plumbing, electric, framing, windows, siding, roof, etc. I have known Chris for 20+ years and was confident that our forever home would be solid and done right. We had a few hiccups throughout the process - as this was done during Covid, so there were supply issues, delays and so forth, but Chris and his guys did an amazing job. We couldn't be happier and are continuously getting compliments on our beautiful home. Chris has been and will continue to be our go-to for any construction needs for us and our family and friends."

OVER 100 YEARS COMBINED EXPERIENCE AS YOU PATIO AND HARDSCAPE EXPERTS! SBC Outdoor Services was founded in 2015 by Brad Crist. Brad had over 15 years of experience in the industry and wanted to create a landscaping company that could hold true to the concept of “quality landscaping.” Ever since then we've been constantly growing as a high-end hardscape, landscape design, and commercial maintenance business. Over the course of our existence, we've earned a great reputation for quality service and we aim to not just maintain our reputation for excellence but to constantly improve it. That's why we only hire the best of the best. Our management team alone has over 30 years of experience in the industry and members of management used to maintain the White House.

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"

FAQs for addition to existing structure building service projects in Fort Washington, MD

Yes, hidden rooms are legal, as long as they meet all local building regulations. If you sell your house, most states require homeowners to disclose full houseplans, which would include any hidden rooms.

If your secret room is a safe room, it should contain a means of communication aside from a cell phone, such as a shortwave radio. You should also have plenty of drinking water, a portable generator, emergency food supplies, blankets, pillows, flashlights, batteries and a first aid kit.

Any time you update your home’s square footage, you increase its value, but a secret room is a niche feature that doesn't rank high on every buyer’s list of must-haves. Investing your money in remodeling more common living areas like bedrooms, bathrooms, or kitchens will have a higher ROI than adding a secret room. Many secret rooms can act as entertainment spaces (think a game room or wine cellar) or quiet spaces (a library or study), so when building your secret room you may want to consider its versatility for when you’re ready to sell.
