Structural Work in Redondo Beach
Redondo Beach retrofits that start by testing the old anchor bolts, then add plate washers, new anchors and plywood where the crawlspace needs them.
"How can we tell whether the old bolts down there still hold?" For a Redondo Beach house the answer comes from a wrench and a cleaned bolt. We check that each nut is snug, that a washer bears on the wood and that rust has not eaten into the shank. Bolts that pass stay in the count. Bolts that fail are replaced or supplemented, and the plan shows which is which.
Testing hardware that is already installed
An anchor bolt needs a nut tightened onto a washer, a sound sill around it and enough embedment in the concrete. A loose nut lets the sill lift and slide before the bolt engages. A small round washer can pull through the wood, so retrofit work uses square plate washers. Where the bolt spacing is too wide, or bolts stop short of the corners, new anchors fill the gaps. Spacing and edge distances come from the plans, and each existing bolt is noted as kept, upgraded or replaced.
Bracing and access in the same crawlspace
Bolts handle sliding, but cripple walls also need plywood to keep from folding over. The sheathing is nailed along every edge into studs and plates, with vent holes drilled in the panels so air can still move through each closed stud bay. Where the space is tight, we plan the order so each wall gets braced without blocking the way to the next. The city building department reviews the plans and inspects the nailing. Whether the parcel falls inside the coastal zone is confirmed early, since outside changes there may need more review.

Structural Work in Redondo Beach: questions
If the floor rests on cripple walls, the house needs both, and old hardware does not settle the question. Bolts keep the sill attached, and plywood keeps the short walls upright. Where the joists bear on a sill laid right on the concrete, there is nothing to brace, so the scope is bolting alone, often with plate washers added.
Within the limits of the code's prescriptive plans, a bolt and brace can be permitted without engineering. Anything larger, such as a beam for an opened wall, a soft-story frame or new footings, gets drawings from a licensed engineer we hire. Redondo Beach's building department reviews the plans and inspects each stage.
Existing anchor bolts. We check each one for a tight nut, a proper washer and rust on the shank, then tally their spacing along the sill. After that we probe the sill for rot and look over the cripple walls and posts before anything is priced.
