Exterior Remodeling and Facade Work Across Los Angeles
Aggregate Construction Group is an exterior remodeling contractor working on single family houses, apartment buildings, and mixed use property across Los Angeles County. Exterior work is judged from the street, which is why owners tend to think of it as appearance work, but the assembly behind the finish is what determines whether the appearance lasts. Stucco cracking, failed flashing at parapets and window heads, and deck and balcony water intrusion are structural problems presenting as cosmetic ones.
Our portfolio leans heavily toward multifamily exteriors, including full facade transformations with new stucco, balconies, ironwork, lighting, paving, and signage. That work carries different constraints than a single family remodel, because the building stays occupied, the scaffolding sits over walkways tenants use daily, and the schedule has to account for notice requirements. We handle the same scope on houses in Brentwood and across the Valley, at a different scale.
Facade, Envelope, and Site Scope We Handle
We handle stucco repair and re-stucco, siding replacement, fascia and soffit rebuild, window and door replacement, decks and balconies, guardrails and handrails, exterior stairs, walkways and paving, retaining walls, courtyard and common area upgrades, exterior lighting, address and building signage, and trash enclosure rebuilds. On apartment property these usually move together, because scaffolding and site protection are a large enough cost that doing the facade this year and the balconies next year means paying for the same setup twice. Finish coating on completed exterior work is done by the same crew behind our exterior painting projects, so the substrate repair and the coating are not two separate warranties pointing at each other.
Balcony, Deck, and Walkway Compliance on Multifamily Exteriors
Exterior elevated elements on California multifamily buildings sit under inspection requirements that most exterior contractors are not set up to answer. SB 721 covers apartment buildings with three or more units and SB 326 covers condominium associations, and both require periodic inspection of balconies, decks, walkways, stairs, and their supporting structure. When an inspection turns up damage, the repair is not a painting job, it is structural work with engineering and permits attached. We run both sides of that, the balcony inspection and the exterior elevated element inspections, and the repair and rebuild that follows. For owners, the practical value is that the findings and the fix come from one team rather than from a report handed to a contractor who then reinterprets it.
Title 24, Envelope Upgrades, and Older Building Stock
Exterior work that touches the building envelope triggers energy code. Replacement windows and doors on residential buildings up to three stories require dual glazing certified by the National Fenestration Rating Council under Title 24, Part 6. Roof replacement past a threshold share of the roof area brings in cool roof product requirements. Projects permitted now run under the 2025 California Building Standards Code, effective January 1, 2026. On buildings from before 1978, exterior preparation that disturbs paint falls under federal lead-safe renovation rules, which changes containment and cost on the large share of Los Angeles multifamily stock built before that date.
