617-719-4200 Alexis Home Remodeling started few years after the purchase of my first home in Boston back in 1992. This triple decker built in 1906 needed more than just a paint job, it needed reliable, honest and motivated professionals. Many hours of waiting for call backs made me think I could do a better job at it. That's why I treat everyone of my customers as I would have want these no show contractors treat me with the respect and professionalism I deserved. Since 1996, Alexis Home Remodeling has walked home owners from the remodeling concept to the finish product. We are fully licensed and insured.

"! EXCEPTIONAL ! Starting with great listening to the attention to details that I was most excited about, to Edian’s / Alexis superior preparation & commitment to on time start & completion, Edian’s professionalism yielded 2 huge projects that are an absolute joy to behold. Edian’s extraordinary attention to details is so far beyond my expectations, that he actually improved upon my architect / engineer’s structural design. I will admit that I expect much much more than most & Edian truly exceeded my standard of ‘triple redundancy’ when it comes to structural strength, safety & my ‘100 year goal’ for major ‘capital’ level projects. His work is so above and beyond, that several tradespeople have commented on the extraordinary level of workmanship! I have had the pleasure of working with Edian on 2 huge reconstructions of porches. For both, he scheduled well in advance and then he & crew showed up a few days early, completing these massive projects on time. Yes, you read that correctly, ON TIME. He & his crew have an exceptional ‘culture!’ They were here everyday, without exception, always cheerful & laser focused on their dedication to getting the job done according to Edian’s strict codes of on time progress. I wish I had space to say more! In short, I cannot wait until I have more work for Edian / Alexis!"

"They were highly rated so i went with them. They provided a project manager that didn't oversee the job and failed inspection because of common mistakes. They blames the window on me for having incorrect size. we eventually got he correct windows they didn't finish the deck properly the cut corners and made excused that it wasn't in contract and i had to pay extra for their inconsistencies. the electrician put thermostat on floor so i couldn't see it.They Blamed everything on me. now the final bill came in and they marked up the bill for a 30 percent markup. I called another contractor to evaluate the work and boy did he find all the hidden things i knew were already wrong. Im not a contractor by the way but i have eyes. "

Mavridis Contracting Services, Inc fully licensed and insured company has been in business for over 20 years servicing all your home improvements and general contracting needs. We specialize in all aspects of home remodeling, additions and decks. We provide craftmanship work, attention to detail and professionalism.

"I wanted a shower expanded. George Mavridis's estimate was very competitive but I hired him because I knew he was honest, quality focused and an open communicator. He has a small crew and excellent subs so he's not super fast. But Mavridis is excellent. One example: The shower needed a new fan, vented through the attic roof. The attic boards were all cut (before my time) in half when insulation was installed. The attic floor was unstable and unsafe. George was very busy but he had his team replace the boards with plywood panels...for 20% less than I expected. Why? Because he wanted to make sure I would be happy when the job was done. I could give 4-5 other examples but you get the point. If you hire George, you'll be pleased."

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