"I can't say enough good things about my experience with Randy Preston and his crew!! Randy helped me renovate a garage that was in SEVERE disrepair into a beautiful and charming studio cottage. The craftsmanship was excellent. I regularly get compliments and feedback that the cottage has the feel of a home that's been there forever (think circa 1940's cottage). The crew was always on time, kept the site neat and clean and were super easy & pleasant to work with. Randy's personality is "steady and calm" - nothing ever felt like a problem - if it was within his power, he handled it and if it wasn't, he helped me figure out next steps. Renovations are rarely stress-free but Randy's nature helped to make it as stress-free as possible. I think the thing I was most impressed with was his transparency and honesty. He was the only contractor that provided me with a fully itemized estimate. I knew exactly how much was budgeted for EVERYTHING and at the end of the construction, he actually credited me back money for things I would have NEVER known cost less then estimated. Every step of the process (that he had control of) was great. I'd hire him again in a heartbeat and hope I do get to use him again for a future project I have in mind. If I haven't gotten the point across yet, I highly highly recommend!!"

"It's with disappointment that I am writing this review and will probably not utilize Homeadvisor again. I don't like writing reviews, especially bad ones for small contractors trying to make a living. Vasco Properties was hired to build an 1800sq foot addition under a residence that I had raised. I went with Vasco Properties because he was willing to do the rough framing, let me take over once framing was done and was offering me the chance to purchase materials at his price. When Vasco  first took the job and reviewed the plans, Adam, owner, advised he could have it done in two weeks. After the house was raised Adam suggested that I put a steel beam in to make lowering the house easier. He also advised that he could have a steel beam within three days. After getting approval from Engineer, the steel beam was ordered. It took two weeks for the beam to delivered, a "far cry" from three days. A second steel beam had to be ordered for another area of the house and it took around three weeks for that delivery. If Adam had stuck to the original plans all that time wasted waiting for beams would not have occured. While I believe Adam and his crew did a good job, he has been horrible when it comes to communication. I have texted, called and sent emails throughout this entire process that will go unanswered most of the time. As I write this review, Adam has not responded to an email sent last week or responded to a detailed voicemail left on his cellphone."

FAQs for addition to existing structure building service projects in Milton, DE

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.
