"I worked for a large supplier to the residential construction industry for 15 years. During that time I visited hundreds of job sites, often with inspectors. I am not a builder, but I know the difference between quality construction and poor. From design through completion, Marvon was top notch! Same can be said for the subcontractors selected by Marvon. Our project included a two bedroom/full bath addition, replacement of flooring throughout the house and a new deck off the addition. We couldn't be happier that we chose Marvon!"

"We ordered a window from them the end of April. The beginning of June they came to put the window in. They had ordered the wrong size.

After waiting a month and not hearing from them, we called to find out when the window would be put in and they said that they would check and get back with us. After many more calls we were told that the window wouldn't be in until July 23rd. We requested a refund and after many more calls were told that they don't give refunds.

FAQs for addition to existing structure building service projects in Decatur, IL

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.
