It is my mission to provide excellence to all our projects and exceed our clients' expectations of the value they will receive by providing professionalism of management, as well as high quality craftsmanship. Trust and honesty are to be the foundation for all our client and business relationships. It is my goal to develop and nurture relationships with our clients and business associates by maintaining a team atmosphere with a common goal.

"Jim is a great guy to work with!!! He was very understanding and responsive to all my questions and concerns. He oversaw the entire operation of removing a wall to open up the living area. This encompassed general demo and construction, electrical, resurfacing, matching texture and repainting. Followed by some special hardwood floor detail work. His team of workers are always excellent and considerate of us and our home. You will not be disappointed! It is very difficult to try and choose a contractor and I feel lucky to have found him!!"

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