"Best in the business! This was the 2nd house I've remodeled and Dave & his team outperformed all previous positive experiences & expectations. They removed 3 pony-walls, installed new porcelain, large tile flooring throughout (2200 sq ft), remodeled the bath to enlarge the shower,-added a modern stand-alone tub, installed new double marble-topped vanity, marble mosaic wainscotting throughout the bath, a marble-porcelain 7-foot long/12-foot high shower with luxury finishes (marble bench & rainshowers) & a chandelier above the tub with sconces flanking a 6-ft long mirror. They renovated the kitchen with new cabinets, pendant lights, quartz countertops on a new, better positioned island that Dave designed, porcelain flooring, under-cabinet lighting, and gas-burning double-sided fireplace before installing gas-top stove, electric wall ovens, refrigerator, dishwasher and double-work sink. They even installed 3 chandeliers (living room, dining & media rooms), drapery hardware at eight floor-length (12-ft high) windows & sliders, and an amazing new wet bar with vessel sink and marble with brass inlay backsplash!! They're prompt, hard-working (many times working on Saturdays and Sundays to meet deadlines), kept the project moving - even with supply delays (store's fault - not theirs) and additions I requested. They're attentive to detail, sensitive to HOA demands (never arriving too early & removing outdoor trash immediately), and professional at every turn - keeping the workspace clean/tidy. Dave goes above and beyond to satisfy his customers, reviving the art of customer service and taking it to a whole new level. For example, and though it wasn't on my list of repairs, he noted that my "new" home's air ducts needed cleaning - and shopped around for quotes I could afford. Likewise, he flushed my failing water heater in attempts to save it (original to house built in 1997). I can't say enough about this fabulous team of professionals who are as kind and personable as they are professional and skilled. I strongly recommend Dave and his team for ANY home remodel you're considering. Dave's part-designer in addition to being a fabulous contractor. He made several suggestions along the way, and I'm glad I took his advice (otherwise I wouldn't have this amazing, gourmet kitchen w/double-fireplace!). I interviewed and researched several contractors before engaging him with most exceeding his quotes by 15-25%. He's reasonably priced, comes when he says he'll be there, and makes sure the client is happy with the final product. (He even checks back a couple of weeks after the job is completed to ensure everything is functioning as it's supposed to.) I'm hiring him for my next project of replacing entry doors, and am absolutely confident he'll do a phenomenal job! THANKS DAVE, LOU and WAYNE!!! You're the BEST!! (And SnowBall sends puppy hugs to each of you!) :)"

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