"Eco Power Works did a great job on my kitchen and bathroom renovation ! Daryl and John were very patient listening to my ideas. They brought in an architect who was reasonably priced and made suggestions to overall designs which I am so glad they did ! The project from Start to finish was on schedule which O was pleasantly surprised - these guys kept their words and their workers were always on time respectful of my property and time. I like that they always checked with me when they took major steps to double check that everyone was on the same page - they communicated every step of the way and were very careful to to do the job right. I really love the beautiful cabinets and marble countertops which were my dreams. I am so glad I hired these guys - they really did a great job overall - will definitely recommend them to my friends and neighbors !"

"I would definitely recommend CasaNova Design and Build to others for their home projects. They renovated my primary bath installing a beautiful walk-in shower, new floor tile, new sink vanity, and more. The crew was on time and did excellent work! The owner, Chris was wonderful to work with. He really made the process way less stressful providing guidance and support making sure everything was done properly. I absolutely LOVE my new bathroom and would hire them again for other projects in the future!"

"Overall, our experience was positive. The pricing was very competitive, and the quality of the products met our expectations. Communication, however, could have been more consistent. Responses to our inquiries were sometimes delayed, and we occasionally received messages late at night. Additionally, working with multiple contacts made the process feel a bit disorganized at times. That said, when communication did happen, they were helpful and responsive. With a bit more coordination, this would have been a near perfect experience."

"The original project I hired them for was to replace leaky faucets in both the kitchen and bathroom. Frank, the owner, was responsive and professional. They scheduled the work promptly and showed up on time. Unexpected issues were discovered that required a second trip and additional work. They communicated everything clearly and the additional costs were handled separately and transparently. They also cleaned up after the work was done. I would hire them again."

FAQs for addition to existing structure building service projects in Leesburg, VA

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.
