Color selection (NP Line Design provides large samples on your walls). Move furniture, cover floors, tape trim and fixtures. Repair nail holes, cracks, dents.
Sand glossy surfaces, scrape peeling paint, caulk gaps. Exterior: power wash, scrape, patch stucco cracks. Prime bare wood and stains. This phase determines final quality.
Full primer on new drywall, repaired areas, or color-change walls. Tinted primer for dramatic color changes saves a finish coat.

“Interior painting in Los Angeles is deceptively complex in 1950s–1970s homes. Pre-1978 construction in the San Fernando Valley has a high probability of lead-based paint. Before any sanding, scraping, or surface prep, we do a lead test — it's the law under EPA RRP, and a responsible contractor in Los Angeles won't skip it. Lead-safe work practices add time and cost, but the alternative is liability and potential health consequences.”
Apply a test patch of your proposed exterior color to a 2x2 foot area of the actual wall in Los Angeles and observe it through a full light cycle (morning, noon, afternoon). In the San Fernando Valley, the high desert light quality makes colors look dramatically different than they do under fluorescent store lighting. This 48-hour test has saved many Los Angeles homeowners from a color they would have hated.
1. Painting over lead paint in a Los Angeles pre-1978 home without an EPA RRP-certified contractor. In the San Fernando Valley, sanding or disturbing lead paint without proper containment is both illegal and dangerous. Any painting project on a 1950s–1970s Los Angeles home requires a lead test first — and if lead is present, an RRP-certified contractor with certified work practices.
2. Using standard latex instead of elastomeric paint on a Los Angeles stucco exterior. In the San Fernando Valley's thermal cycling climate, standard paint cracks along hairline stucco movement within 2 years. Elastomeric coatings flex with the substrate and bridge minor cracks — they're the correct product for exterior stucco in Los Angeles and cost only marginally more.
3. Skipping the primer coat on bare wood or repaired surfaces in a Los Angeles paint project. In the San Fernando Valley's dry climate, fresh spackle and patched drywall are porous and absorb finish paint unevenly, causing visible 'flashing' — shiny and matte areas in the same wall under raking light. A dedicated primer coat on all repairs is non-negotiable for a quality finish in Los Angeles.
If a Los Angeles painting quote is 50%+ below comparable quotes, ask how many coats are included and what prep is included. In the San Fernando Valley, low-ball painting quotes almost always mean: one coat, no primer on bare areas, no caulking at penetrations, and minimum prep. A one-coat exterior paint job in Los Angeles's UV environment starts failing in 2 to 3 years.
Interior painting in a typical Los Angeles home (2,000 sq ft) costs $4,500 to $9,000 for walls and ceilings. Trim and doors add $1,500 to $3,000. In the San Fernando Valley, costs run at the LA metro average. Cabinet painting (not resurfacing) adds $2,500 to $5,000 for a full kitchen.
Exterior painting for a typical Los Angeles single-family home costs $4,500 to $10,000. Prep (power wash, scrape, prime) represents 60% of the cost. Elastomeric paint for stucco exteriors in the San Fernando Valley costs slightly more than standard latex but significantly extends the coating life in Los Angeles's climate.
Elastomeric exterior paint is the correct product for stucco in Los Angeles. It flexes with the San Fernando Valley's thermal cycling, bridges hairline cracks up to 1/16 inch, and resists the alkalinity of stucco substrates. Apply over an alkali-resistant primer for best adhesion and longevity in Los Angeles's climate.
Yes, if the home was built before 1978. Pre-1978 homes in the San Fernando Valley may have lead-based paint. Before any sanding, scraping, or aggressive surface prep, a lead test is required and EPA RRP (Renovate, Repair, Paint) certified contractors must use lead-safe work practices. NP Line Design follows all EPA RRP protocols on Los Angeles homes.
