"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."

At M Y Real Estate and Construction, it is our mission to provide the highest quality of service in all aspects of our business. We are extremely thorough in services that we provide and aim to be very receptive to any client's issues, questions or concerns and handle them promptly and professionally. We take necessary steps to ensure that our clients are completely satisfied with all of our contractual and assumed responsibilities. Above all else, we will fulfill these responsibilities while maintaining the highest ethical standards in both of our work and our character.

"Moses and his team were phenomenal to work with. From the moment we met when we first discussed my project, he instilled me with confidence. He allowed me to see current projects he was working on similar to mine, he genuinely listened to what we wanted and made relevant, excellent suggestions to ensure that our project would meet our expectations, and stay within our budget. He came with excellent recommendations from his previous clients, of which I'm now proud to be one. His communication was always excellent, he didn't mind answering all my ignorant questions, and he worked seamlessly with my architect and kitchen/bathroom designer in order to complete the project within a reasonable timeframe given the scope of the project. Moses consistently went above and beyond expectations in order to make the project as stress-free for me as possible. His team worked tirelessly and while my family and I had to move out of our house due to the nature and extent of the project, he kept in constant contact with me, arranged frequent in-person meetings, and didn't mind me and my kids showing up unannounced to view the progress. My neighbors constantly told me how hard he and his crew were working, as they saw him on-site nearly every day. I would hire Moses and his team again, for any construction project, without hesitation and cannot recommend him or his hard-working team enough. If you are anxious about all the "contractor nightmare" stories out there, hire Moses and his team - you won't regret it! Outstanding!"

His men are true craftsmen and were able to resolve every issue with ease and professionalism. Cesar is very communicative and always available to discuss plans and changes. The work is superior and the finished product is stunning. I couldn't be happier and wholeheartedly recommend them."

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