"They were awesome. Went above and beyond. The price never changed. They were clean and meticulous and wanted to make sure we were happy. I even decided I wanted a bigger tub after he brought in the original one and I had him take it back. They did not complain or charge me more for the work. They are honest hard working, I can’t say enough positive things. The only negative and not really because it was Christmas time was a slight delay.

"It went great! The crew that did the work were diligent and professional, polite and courteous, respectable to me personally, to my home. They did a great job of cleaning everything up when the job was done. We had a couple of little kinks. They were taken care of quickly with apologies. The completed new bathroom is even more beautiful than I could have anticipated. Gorden was easy to work with. He explained everything and helped with decisions. He is respected by his crew. I'm completely pleased with the work performed. When I'm ready for another project G.R. Construction Co will get my call. Thanks Gordy and your crew for my beautiful new bathroom."

"Nathan was amazing. Arrived on time every day and stuck to his time line. He let me know every time there was something we didn’t see and went the extra mile on the whole project. His rates are reasonable and he saved me a lot of time by providing materials for the job. I am definitely going to use him for my other bathroom. I like that my project was his sole job for the week and I didn’t have to extend the project with off days. He had a helper who was so respectful and kind. Both Nathan and Ryan were great with our dogs too. Very patient."

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