Groundwater & Basement Water Intrusion in Alhambra, CA
Basement seepage, failed sumps, and hydrostatic pressure against the foundation are extracted and dried, and the path from the ground is identified so the loss does not repeat. Groundwater and basement seepage are extracted and dried only after the path from the soil is identified — a wall, a slab, a drain, or a failed sump. Drying the interior without stopping that path returns the same water to the same floor.
Frequently asked questions
There is more building on the lot than there used to be.
That is the common situation here and it is usually the explanation for water that is new. Every addition, patio and paved side yard covers ground that used to take rain, and none of them individually seems significant. The whole of that runoff then goes to whatever low point exists, which is often against a wall or over a property line. Walking the lot during rain shows where it has ended up.
The water goes straight onto the neighbor's side.
On lots this narrow, with buildings close to the line, that is frequently where it has nowhere else to go. It is worth addressing early rather than after it has become a dispute, because the practical fix usually needs both sides: a shallow channel along the line, a downspout carried to the street, or a change to what is paved. Photographs during rain make that conversation about facts.
Nothing has rained since March. What should be checked?
Roof drainage, in October rather than after the first storm. Eight dry months are enough for a seal to fail, a flashing to lift or a gutter to fill with debris and nobody to know, and the first real rain finds all of it at once. An hour up there before November prevents more damage here than most drainage work would.
