"Exceptional...and that is only one word to descrobe the team from Whitney Homes crew we had a 2 bathrooms renovated and major electrical work done all done in a samll amount of time. Courteous, clean, well-mannered, and respectful of our home. The job that was done wass above our expectation. They described the work to be done to us, gave us a very very good price and did the work. THere was some snags with Home Deopot but the team worked around those issues without us having to do much. Very good will definetly recommend this company for any project you may have in your home. I added two small pics but they also added two new 20 amp circuits because our house was old and couldnt handle the load we were putting on it. The pictures don't do the work they did justice."

"The employees were great. A couple of days there was only 1 man on the job due to illness. The company did not replace him, so the 1 man had to work alone, slowing down the completion of the project. Art and Johnny were great to work with. Communication with the office was a little lacking, but overall we are happy with the work."

"We could not be happier with the remodel of our dated, dysfunctional, tiny kitchen. Ruben was very professional, friendly and a real problem solver. He continually went above and beyond and we simply cannot say enough about what a great contractor he is. We had an unforeseen deadline and he and his staff worked very hard to make sure the job was finished. Their work was meticulous and the final result outstanding. Thank you Ruben and staff!"

FAQs for addition to existing structure building service projects in Guerneville, CA

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.
