"Very well! Joe worked closely with us to satisfy our dream of having our 'East Coast' screened in deck in the PNW. He was transparent about the unknowns and worked hard to find answers and solutions. Although it was a costly project, we are pretty sure the final product costs were significantly lower than our other bid(s). Joe found very high quality sub-contractor workers and negotiated to a favorable price. And, he also held true to his word. Specifically, he made right when property damage occurred (that was a result of unanticipated weather) and honored original estimate costs even when some contractor labor was much more extensive than first anticipated. We are very pleased with our finished covered and screened in deck and would highly recommend Joe as a knowledgeable, trustworthy, fair contractor who communicates well and often."

FAQs for addition to existing structure building service projects in Sandy, OR

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.
