"I chose this company after comparing three other quotes and initially felt confident signing a contract with them. Unfortunately, my experience was extremely disappointing and frustrating. I hired this company to build an outdoor bar and stamped concrete patio. The bar should of only taken 7-10 days but dragged on for 8 weeks. Workers showed up once a week for only a few hours, and communication was terrible ? I constantly had to text and call for updates and got a 24 hours? notice before they arrived. They even started work before the permits were approved; I had to contact the county to find out. While I?m happy with the finished bar, they never completed the patio that was in our signed contract and stopped responding altogether. I ended up hiring another contractor to do it. The craftsmanship on the bar is fine, but the company?s professionalism, communication, and reliability were awful. I would not recommend this company. "

"Fantastic! Devin and his team remodeled three of the four bedrooms in my townhouse in Clarendon: the first about four years ago and the other two bathrooms two years ago. He also built me a new closet in the master bedroom. The entire experience was amazing. The work is top quality - years later it still looks perfect and I have not had any problems - and his team is polite, professional, timely and they left my home spotless when they left. And since the work has been completed, Devin has helped me with little issues for free whenever I needed help. He is truly a talented professional and a stellar person. Can’t recommend highly enough!"

FAQs for addition to existing structure building service projects in Germantown, 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.
