***Howard General Contracting has the knowledge and expertise to assist you with all of your home improvement needs. Our company is known for our quality craftsmanship and timely work. Howard General

"Guy subbed out most of the hard work and that work was done fairly well and on time. However, he personally tried to do the kitchen cabinet install and ending up walking off the job after he could not fix what he butchered...We hired a professional cabinet installer who took them all down started over and completed the job properly. And for extra bonus, the new shower in the new bathroom he installed leaks into the kitchen ceiling. good stuff. He misses details and misleads when it suits him. We needed a lawyer to help us disengage from him properly and our still finding problems with his work and professionalism several years later."

"We were very pleased with the job performed. Helio's team expanded and renovated our small master bathroom. We took out a large closet and converted it into our shower. Once started, they worked quickly and efficiently. We did have a few small hiccups, namely using our garage to cut tiles and mix thinset, which created an exorbitant amount of dust coating my tools, bikes, and anything else that was stored in the garage. We also had an issue with the cleanliness of the home after some of the workers left, however, after we brought it to Helio's attention, he made sure to tell the team to do a better job moving forward. Contract was a little confusing, so I would encourage many questions to clarify things ahead of time such as timeline for selecting certain items, confirming when the next payments are due etc. All in all, we're pleased with the project and how it turned out."

"This company is fabulous. Renald and his workers gave a great estimate, and did the job flawlessly designing and executing the building of my exquisite patio. He met us at the supply house to help us pick out materials, he took a personal interest. Beside our beautiful patio, I had him redo our fireplace which looks like a work of art! And since the chimney needed some attention, they fixed some problems with the chimney. All work was beautifully done. I recommended this company to friends of mine, and they hired Renald and his crew and got back to me as to how terrific they found his work and the ease it was to work with them. This is how things should be....attention to detail, quality craftsmanship! I'm happy I could submit this review!"

"We hired Tomasetti Builders & Remodelers at the end of 2020 to renovate our kitchen. The project involved completely gutting the old kitchen and opening up the walls to make it an open space to our dining room and living room. In addition, we added a slider to the dining room area. The project was scheduled to begin November 2nd and began as planned. The owner Larry and his wife Joyce were very nice to work with when preparing the contract and initiating the project. Prior to meeting Larry and Joyce, my husband and I had a design of the new kitchen already, but Joyce took us to the stores they engaged with on a regular basis to select kitchen items such as the backsplash, floor tiles, and kitchen faucet. Joe was the project foreman and the one we consistently worked with on a daily basis. Joe came with his co-worker Mike to perform the work. They were extremely professional to work with and Joe was an excellent communicator. Joe provided daily summary updates on the days they worked on the project in addition to next steps. When I reached out to Joe, his response was prompt in providing answers to my questions. Joe ensured the contractors were kept informed of the situation and adjusted their scheduling as needed based on project progression. Both Mike and Joe worked hard every day they were present and Joe ensured the job progressed so that it was complete as close to the agreed upon timeline, as possible. Joe ensured the job met our expectations. Our satisfaction was his ultimate goal. Mike and Joe are the reason our kitchen renovation was done exactly how we wanted. We are ecstatic with the renovation results and would recommend hiring Tomasetti Builders with Joe and Mike working on the job."

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