We are the largest granite fabricator on the Delmarva Peninsula. We provide services for builders, kitchen & bath contractors, and retail. We offer the best customer service and do the highest quality work. Please visit our showrooom and choose your granite slabs.

"That Granite Place was hired to install Quartz countertops in a home I owned by the general contractor, Garrison Homes. The countertops were installed incorrectly (on an angle) as well as cut incorrectly. Despite countless emails and phone calls, they refused to do the repair since they were paid in full. The operations manager, Mark Widen, said his hands are tied and that they wont honor the repair or warranty. I wouldn't EVER deal with this company again nor would I recommend them to my worst enemy!!!"

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