"They removed old pink tiles from my bathroom which took them a week to accomplish. They installed sheetrock and vanity and then repainted wall behind vanity. They installed new 12" x 24" tiles above the old tub and in separate walk-in shower next to tub. a new final plank flooring was put in. New medicine cabinet and towel racks were then install. I had purchased all equipment for bathroom. The estimate for the removal was about $15,000.00 In the middle of the project I was told an additional $7,000.00 was needed do to higher labor costs. I had no choice but to pay a 33 percent increase in order for them to finish the job. I would not hire them again."

Remodeling general, kitchen, bathroom, finish carpentry and framing, small addition and decks. We do not offer solar panel installation or services.

"Fantastic company, highly recommended! I had a garage in an 80+ year old home turned into a finished game room / home gym, including sliding glass door and closet for storage. Highly competent from the framing down to the last details of trim work, it was all very well executed. There were a number of utilities in the space requiring access post remodel. The design was well thought out and aesthetically pleasing to the point they look like design features! The rest blends seamlessly into the space. The sliding glass door that replaced the garage door looks like it was there from the beginning, and the exterior trim blends perfectly with the house, with the added benefit of being waterproof. The communication was great all the way through the project, from start to finish. I would absolutely use them for any future remodel!"

FAQs for addition to existing structure building service projects in Groton, CT

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.
