"We hired Erick and his dad to complete stairs and cut out an opening for the stairs. Although he was paid in full to complete the work, he did not finish it. Furthermore, he was also hired to complete a master bedroom addition for us. He ultimately ripped our roof off of our house and fled with over $25,000. The lack of a roof caused us thousands of dollars in damages and he still would not come back to at least put a roof back on. He also purchased materials for us just so he could steal it. He has been the worst and shadiest contractor that I have ever dealt with and I hope anyone that is thinking about hiring him doesn't. "

"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!"

"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."

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