Can new stucco match the original texture on an older house in Altadena?

Yes, with patience at the trowel. A sample is made, left to cure fully and compared with the wall in several lights. Hand-troweled walls call for copying the motion of the trowel, and color is matched against a chip of the old finish. Recoating the full face is sometimes a reliable route to an even result.

What causes stucco cracks on older houses in Altadena?

Shrinkage as plaster cures, framing movement and water behind failed flashing cause most of them. Corners of openings break first because stress gathers there. Cracks that are stained or hollow suggest moisture inside the wall. Cracks near vents or eaves can also point to details that were never properly built.

Should old wood siding in Altadena be repaired or replaced?

Repair wood siding while the boards are sound, and replace the ones that have rotted with matching profiles. Where ember resistance is a concern, worn wood can be swapped for cement plaster or fiber cement, which is an option to discuss for those walls.

Behind an older Altadena stucco wall, the hidden part that changes a job is often at the top: open eave gaps, an unscreened attic vent, a wood fascia tucked behind the plaster edge. Some Altadena lots sit in mapped fire hazard areas, where ember-resistance requirements can apply, and what the opened wall shows decides which details must be rebuilt.

Gaps embers can use

Embers drift and settle in any opening they can reach. A vent with wide mesh, a gap where the plaster stops short of the eave, an open soffit or a window frame with failed seals can each let a glowing piece inside. These places are examined and opened up if needed, because they cannot be judged from the ground. What is found shapes the list of repairs more than the visible stucco does. Each opened gap is written into the findings, so the reason for every repair is clear before work proceeds.

What a finding changes

Wide-mesh vents are replaced with ember-rated ones. Open eaves are closed with boxed soffits. Fascia hidden behind plaster is cut back or swapped so plaster, paper and metal meet in the right order. Plaster that is cracked or hollow near these details is rebuilt, since a patch there leaves the weakest spot untouched. The scope names each change so any added work is explained. Metal flashing at the eave-to-wall junction closes the last route for embers once the plaster is finished.
