We are a family owned and operated home improvement company with over 20 years experience. We specialize in kitchens, baths, and basements Our commitment to you is: Quality work at an affordable price with personalized attention to your needs.

"From time I read his reviews of other's I couldn't wait to meet JERRY. After having weekly consultations we were convince we made the right decision without meeting with anyone else. His ideas and suggestions matched our thoughts perfectly. There was no rush on his part for us to make a quick decision. Our original idea was to only have a center island installed and possibly refurbished our 45 year cabinets. But his price quote and latest design in cabinets, plus removing an existing wall that separated the dinning room and kitchen will provide more light and space, plus it will upgrade our home to more of a modern look. To meet a contractor unknown for the first time it was a joy to have chosen DAUGHTRY CONSTRUCTION."

"I can’t say nice enough things about the process of working with Martin. We decided to finish our basement, including a full bathroom, while I was pregnant and wanted the job wrapped up before the baby came, which gave a very hard deadline. Not only was Martin able to work with us contacting him two months out on this project, he was so responsive during the process, gave us great ideas, and kept us well-informed on everything that was happening with the project. From start to finish, we always felt that Martin was knowledgeable about what he was doing and didn’t seem bothered when we had last minute changes. The entire team was so clean, which gave me comfort given that I was pregnant at the time, and they were able to complete everything before the baby came. If I had more basements, I would definitely call Martin!"

FAQs for addition to existing structure building service projects in Dover, PA

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.
