Deck and Balcony Work Eight Miles from Downtown

Roughly 42 percent of the housing in Alhambra is owner occupied, which means most of it is rental, and most of our work is what comes with that: walkways serving several units, open stairs, and balconies stacked one above another. The city occupies the western San Gabriel Valley, about eight miles east of the downtown Los Angeles civic center.

Stacked balconies fail in a predictable order. Water gets behind the coating where the deck meets the building, soaks the ledger and the joist ends, and shows up a floor down as a soft tread or a brown ring on a ceiling. By then the framing has been wet through more than one rainy season.

One local requirement catches out of area contractors. Alhambra asks for a Contractor's Report from any construction company working in the city, verifying that each subcontractor holds a valid business license for the construction period. We have that in order before the first day rather than after a stop notice.

Work on an occupied building gets sequenced. We stage a shared walkway in sections so every unit keeps a route to the street, guard the open side overnight, and settle where the debris goes before anything comes off it.

Scope runs from a single balcony over a carport to a full walkway system on a courtyard building. We fabricate the iron too: guardrails rusted through at the base, stair stringers that have lost section at the concrete, and replacement precast treads.

Pulling a Permit in Alhambra

Permits and inspections run through the Alhambra Building Division, which provides plan review and construction inspection and regulates design, construction, quality of materials, use and occupancy. The Contractor's Report covering subcontractor licensing goes to the Finance Department separately and has to clear before permits are finalized, so we get it filed early rather than let it stall the job at closeout.

Waterproofing Problems We Solve in Alhambra

  • Shared walkways that pond after a storm and hold water at the unit doors
  • Stacked balconies where a leak upstairs shows up two units down
  • Rot in the ledger and joist ends where a deck meets the wall
  • Stair stringers rusting out at the base where steel meets concrete
  • Coating that stops at the wall instead of turning up behind the finish
  • Guardrail posts bolted through a deck with the penetration unsealed

Waterproofing in Alhambra: Your Questions

Do you handle the Contractor's Report Alhambra requires?

Yes. The city asks for it from any construction company working here, confirming every subcontractor holds a valid business license for the construction period. We file it with the permit package rather than after an inspector asks.

Will tenants lose access to the walkway during the repair?

No. We sequence a walkway in sections so each unit keeps a safe route in and out, and any open edge is guarded before the crew leaves for the day.

The balcony above me is staining my ceiling. Is a recoat enough?

Usually not. A stain below means water has already reached framing, so we cut the deck back at the wall and check the ledger and joist ends first. Coating over wet wood buys one season.
