Live and work in total privacy with Granahan Construction of Oceanside, California. Backed by more than 25 years of experience, I am a trusted contractor specializing in total soundproofing services. My firm is completely family-owned-and-operated, providing you with a level of personalized service you won't find anywhere else. I go above and beyond to make my clients feel comfortable. My primary goal is your complete satisfaction. I am a member of the National Association of Music Merchants™ (NAMM) and The Blue Book Building and Construction Network for Southern California. Additionally, I am listed under Sound and Vibration Control. Typically, industry professionals use this network to hire licensed and bonded contractors. I pride myself on having an open ear and an open mind. I listen to what you need and want from your soundproofing project. My crew and I can install effective soundproofing materials into walls and ceilings without damaging the beauty or aesthetics of even the most refined home or office.
