"Zach at Reichelt construction built a garage for us. We are incredibly pleased with the final product. He was communicative, asked for our input, and was professional throughout the process. He even helped us out afterward when we needed to get an electric vehicle charge installed quickly. It was not inexpensive by any means, but it was definitely a reasonable price given the quality of the work and materials. It took a few months beyond the six months stated in the contract, but we have come to expect this with projects such as this one, and we never pushed to have it done faster. We could not recommend Reichelt CC enough if you have a job you want done right."

"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."

"Adie was a pleasure to work with, and his crew really knew what they were doing. His quote was far below quotes by other contractors (normally a warning sign), but he clearly knew his stuff and my confidence in him was well-founded. I changed several details as the project went on, and Adie was happy to work with me and make any adjustments. There were delays caused by tile suppliers, but Adie worked to find other sources, and rearranged other commitments to make sure our project was completed as soon as possible. My only constructive criticism is that the quote was not itemized (which was ok for me at the time), but that caused an underestimated cost of the glass enclosure to go unnoticed in the budget until the end of the project. We’d made many changes over the course of the project, so were not unprepared for the higher cost of the glass, but I’d have known sooner if the budget had been itemized. Overall a great experience though and I would use East Bay again in a heartbeat!"

"This past fall we had the front and side landscaping of our house completely redone by White Oak, and we are extremely happy with the result! After speaking with several landscaping companies the decision to move forward with White Oak was very easy. They got back to us very quickly and came to the house to discuss the project in detail. Both Shannon and Matt were very responsive with inquiries, including stone and plant selections based on our preferences. They also put together a render and discussed all details before kicking off the project. As part of the project they had to relocate some sprinkler heads, something that other companies would not do. Hats off to Shannon, Matt and the rest of their team - they are punctual, friendly, and hardworking. I highly recommend them and will certainly reach out to them for future projects!"

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