"I recently had Advance Guard build a new deck and replace my old wrap-around porch, and the results are outstanding. From the start, Dave was professional, knowledgeable, and passionate about his work. He listened to my ideas, offered valuable suggestions, and kept me informed throughout the process. The craftsmanship was top-notch, with great attention to detail. The new deck is spacious and beautifully designed, using high-quality materials. The porch replacement blends seamlessly with the new deck. The job site was always clean, and the project was completed on time and within budget. Dave was approachable, communicative, and dedicated to customer satisfaction, making the entire experience enjoyable. I highly recommend Advance Guard for any home improvement projects. The new deck and porch have transformed my outdoor space into a stunning area I'm proud to show off."

"We hired Brennan and his company when he first started his company, years ago. We had to structurally change the living room and dining room prior to renovating the kitchen. By the end of the project we had an entire open concept first floor, and brand new kitchen. Between the workmanship, communication, dedication to show up on time, when they said they would, I would highly reccomend B LaGrassa Construction. "

"We added a great room, entryway, deck and second floor room to a ranch. Kip has a great design sensibility and we worked together without an architect to come up with a plan. We've been extraordinarily happy with the result; we love the house. The older section works seamlessly with the newer section. Kip pays attention to details. After the work was done, Modern Habitat has been responsive to whatever issues that arose. We are truly appreciative!"

FAQs for addition to existing structure building service projects in Westborough, MA

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.
