Seismic retrofits and foundation work in South Pasadena

Aspenwell Construction anchors sills, sheathes cripple walls and mends footings under South Pasadena houses, with the city reviewing drawings first.

The joint between a South Pasadena house and its concrete is where our attention goes first. On an inland suburban lot, that wood sill spends most of the year dry, then takes on water during the odd hard storm, and the swing between the two loosens nails and invites rot at the edges. We check whether bolts tie the sill down, whether the wood is still sound, and whether the short walls below the floor carry any bracing at all.

Reading the sill and the footing

A flashlight and an awl tell us most of what the sill can still do. Soft wood near the vents or under a downspout gets marked for replacement, and any crack in the footing gets measured for width and followed along the length of the wall. Where a crack stays hairline and the concrete rings solid under a hammer, new anchors can go in beside it. Where the edges have shifted out of line, an engineer looks at it before any bolt is drilled, because a bolt only helps when the concrete around it holds.

Bracing, drainage and the city review

Plywood on the cripple walls turns them from a hinge into a stiff panel, and the nailing schedule on the drawings sets how firmly it grips. Before we close up, we look at where roof water lands. A gutter that empties against the foundation keeps soaking the same corner, so we may suggest an extension or a shallow swale to carry it off. South Pasadena reviews the plans before the work begins, and an inspector checks every anchor and the plywood nailing before any finish hides them.
