What an excellent experience it has been working with that company on our basement renovation! The job was done earlier than planned and completely on budget. They brought unmatched enthusiasm, creativity and professionalism to the project, worked within our vision. They took care each day to clean up after their work and remove any dangerous items that could cause trouble for our toddler. We now have twice the house we had only few weeks ago, and look forward to each new guest that comes through so we can show them all the little details that made this project so special.

House Bolting Pasadena, CA

House Bolting or Earthquake Retrofitting in Pasadena is the process of attaching a house to its concrete foundation using foundation plates and anchor bolts. California is "earthquake country" and we who live here should be aware that the up-and-down and side-to-side motion of an earthquake can shake an unbolted house off its foundation.

Foundation bolting typically means that bolts are added to improve the connections between the wooden framing members of a building and its concrete foundation. Usually this means adding bolts through the piece of wood that lies flat on top of the foundation, referred to as the sill or mudsill, into the concrete. There may be no existing bolts, or the existing bolts may be either weakened or too far apart to be strong enough for earthquake resistance.

Contractors Pasadena are highly trained in foundation bolting and the bracing of cripple walls by using structural-grade plywood which provides greater resistance to earthquakes. These measures, along with properly fastening the floor system down with approved framing anchors, will make your home a safer home in Pasadena, CA.
