"Efrain and David are fantastic! When our contractor was suddenly unable to continue with the job, David took over with a great positive attitude. He persistently worked with the city to get the building permit, finally ending a tedious 10 month process. Crews were here working every day. Each one of them was considerate, conscientious, and demonstrated a strong work ethic. Efrain and David communicated with us most days and were always accessible to us. My ADU is adorable and just what we wanted and I am sure that many contractors could have pulled it off. The important thing about Olalde is that they truly care and honestly want us to be happy."

At American Home Improvement, Inc. it is our mission to provide the highest quality of service in all aspects of our business. We are extremely thorough in services that we provide and aim to be very receptive to any client's issues, questions or concerns and handle them promptly and professionally. We take necessary steps to ensure that our clients are completely satisfied with all of our contractual and assumed responsibilities. Above all else, we will fulfill these responsibilities while maintaining the highest ethical standards in both of our work and our character.

"When my bathroom started showing its age with leaky pipes and outdated tiles, I called American Home Improvement for a remodel. They were professional from the start, helping me pick out materials that fit my budget and style. The crew was friendly and explained each step, from installing the new vanity to laying fresh flooring. It took about two weeks, but the results are stunning, brighter, more functional space that my family loves. No surprises with costs either, everything was straightforward. If you need a bathroom upgrade, these guys are solid."

"My bathroom was remodeled by Moriah. It is now much more modern and minimalistic than it was before. I have new flooring, sophisticated recessed lighting, LED lighted mirror and a brand-new floating vanity that has a spa look with the wood door and above counter sink. The entire bathroom was painted a pretty blue color including the walls and ceiling. Even the door was re-painted white. I also have a new toilet bowl. I already had an existing shower that had recently been installed. Fantastic job!"

Frontier Remodeling is your area leader for all of your home improvement needs. We know that customer service is key to a job well done, and ours is the best around. When you want top quality work at an always fair price, call the professionals at LLB Remodeling.

"hired Frontier Remodeling for a home remodel, and it was a mistake. I selected them based on Aron telling me his guys were skilled, focused on quality, efficient, and clean. I experienced none of that. Work progressed slowly for 3 months. They rushed and cut corners at the end so they could finish and get paid. Quality was very poor, workers did not respect my property, and my new home was an unorganized filthy mess for 5 months. The only thing about Frontier Remodeling that was organized and punctual was Aron asking for progress payments. In the end, I had to hire other contractors to correct a fair amount of work."

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