There was days will he come at 9am and left 12nn and stated that how will needed to work other job site. and he wouldn't be at our work site a whole day and complain already multiple times to the project manager Justin rowe. We keep reminding them to put a shoes to protect our floors and we paid so much for the floor and the labor . They had a gasps in the baseboard and everything and already paid 5000 and its original charge 7200 but we thought we had hire a professional work done but we had hire somebody else to fix the job and we paid a lot of money thinking this was the trust worthy company but we took advantage and Justin cared about collecting my husband and needed a check to get the month quota and the job was not done and we are disappointed and we spend a lot of money for this project.

"My project was a major renovation of a 1985 Victorian home that suffered a devastating fire. Erik and his team did a beautiful job following my architect’s plans, and was also proactive about calling out necessary changes. He was very patient with all of my changes and very specific requests, and was a very calming influence when unexpected surprises inevitably arose during construction. The final results are beautiful, and an historic house has been saved. I look forward to working with Erik again in the future!"

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