Flooring installation in a typical Los Angeles home takes 3 to 10 days. LVP and laminate take 2 to 4 days. Hardwood takes 5 to 7 days including finishing. Tile takes 5 to 10 days.
Move furniture, remove existing flooring, inspect and repair subfloor. Level low spots, fix squeaks. Acclimate new material (hardwood needs 3-5 days).
Self-leveling compound for uneven areas, moisture barrier installation, underlayment. Critical for LVP and hardwood longevity.
LVP: click-lock floating installation (fastest). Hardwood: nail-down or glue-down. Tile: mortar bed, tile setting, spacers, grout. Large-format tile takes longer.
Threshold strips between rooms, baseboards reinstalled or replaced, stair nosing, quarter-round trim. Caulking at fixtures.
Hardwood: sand and finish if site-finished (3 coats, 24hr between). Tile: grout sealing. Final clean, furniture replacement, walkthrough.
LVP (Luxury Vinyl Plank) is the #1 choice in LA in 2026: waterproof, durable, affordable ($5-$10/sqft). Engineered hardwood for high-end. Porcelain tile for kitchens and indoor-outdoor transitions.
Usually no — work can be done room by room. However, for whole-house hardwood with site-applied finish, the fumes require 24-48 hours of vacancy after final coat.
