Substrate preparation
Old tile, adhesive and damaged substrate come out, floors are levelled, and shower walls are checked for sound, plumb surfaces before tile starts.

Tile Installation in Los Angeles
Tile only looks as good as the substrate beneath it. Level, waterproofed and properly prepared, tile lasts decades; set over a moving or damp base, it cracks and loosens within months. This page explains what tile installation involves across floors, showers and backsplashes in Los Angeles homes.
Careful work. Honest options.
About this service
Tile Installation in Los Angeles: What the Job Actually Involves
Tile installation sets porcelain, ceramic, stone or mosaic tile on floors, shower walls, tub surrounds and backsplashes, with waterproofing where water is present, levelling where floors are uneven, and grout and sealant finishing the joints. Shower tile is a waterproofing job; floor tile is a levelling job; backsplash tile is a layout job — and a written scope should say which one each area is.
Tile cost varies by tile size and material, substrate condition, waterproofing scope and layout complexity; pricing is set out in a written estimate after the site visit. The scope below is what a written estimate should itemise instead.
- ✓ Substrate level, dry and sound
- ✓ Waterproofing system in wet areas
- ✓ Layout planned before cutting
- ✓ Grout and sealant finished as a system
What's included
What Tile Installation Covers
Tile scopes differ by area, but substrate, layout and finishing stages are shared. The stages below cover floors, showers and backsplashes.
Waterproofing in wet areas
Shower membranes, seams, corners and drain connections are built as one system before tile, since tile and grout alone are not waterproof.
Layout and dry-fitting
Tile layout is planned from the most visible wall or floor line, so cuts fall at edges and patterns stay centred where they matter.
Setting and levelling
Tile is set with the right adhesive and levelling system for its size, so large-format tile does not lip and small mosaic stays flat.
Grout and sealant
Joints are grouted, movement joints are sealed rather than grouted, and stone is sealed where the material requires it.
Final check and care notes
The finished tile is checked for lippage, hollow spots and grout consistency, and care notes for the tile and grout are left with the household.
How it works
How Tile Installation Runs, Step by Step
The area is measured, the substrate is checked, and the tile, pattern and layout are chosen with cuts and focal points planned.
Substrate repair and levelling, then the waterproofing system in showers and wet areas, inspected or cured before tile covers it.
Tile is set in sequence — floors before walls where the design requires it — with levelling and spacing kept consistent.
Grout goes in after adhesive cures, movement joints are sealed, and the surface is cleaned and checked.
The finished tile is walked and checked against the written scope, with any lipped or hollow tile corrected before handover.
STEP 01Survey and layout decision
The area is measured, the substrate is checked, and the tile, pattern and layout are chosen with cuts and focal points planned.
Tools & methods
Tools and Methods We Use for Tile
Wet tile saw
Porcelain, ceramic and stone are cut wet for clean edges, with layout planned so the hardest cuts fall where they are least visible.
Levelling systems
Clips and wedges keep large-format tile flat across the floor or wall while adhesive cures.
Substrate testing
Level and moisture checks map the base before tile starts, so levelling and waterproofing are scoped up front.
Waterproofing application
Membrane, banding and sealant are applied as a continuous system at seams, corners and penetrations.
Grout and sealant finishing
Grout is applied and cleaned in stages, and movement joints are sealed with flexible sealant rather than rigid grout.
Real results
What This Work Involves
Tile Installation
What tile work involves in a Silver Lake home
Silver Lake tile work in 1920s bathrooms and kitchens often means small-format or period-appropriate tile over older, uneven substrates. Levelling and waterproofing decide the result more than tile choice.
Tile Installation
What tile work involves in a Los Feliz home
Los Feliz tile scopes range from Spanish Revival bathrooms with patterned tile to mid-century kitchens with large-format floors. In both, the substrate and layout plan come before the tile order.

Problems we solve
Tile Problems That Surface During the Work
Tile failures almost always start below the tile. These are the problems to scope for.
Ask a pro →Tile cracking after installation
Cracks trace to substrate movement, missing expansion joints or an out-of-level floor — all fixed in preparation, not by re-grouting.
Shower leaks behind finished tile
A leak behind tile means the membrane, drain or a joint failed. Waterproofing is built and checked before tile, not after.
Lippage on large-format tile
Large tile lips when the floor is uneven or levelling is skipped. Levelling systems and a flat substrate prevent it.
Grout staining and cracking
Grout cracks at movement joints that should have been sealed, and stains where sealing was skipped. Joints are finished as a system, not as an afterthought.

Porcelain is the common choice for water resistance and durability, with mosaic or small-format tile for shower floors where slope to the drain matters. The substrate and waterproofing matter as much as the tile.
Tile alone, with no plumbing, electrical or structural change, is generally cosmetic work. If the scope moves drains, alters waterproofing membranes or opens walls, the permit path changes — confirm the scope against current LADBS rules.
Tile and grout are not waterproof. The membrane system behind tile is what keeps water out of walls and floors, and it must be built before tile goes on.
It depends on area, tile size and substrate preparation. Waterproofing cure times and grout stages add days that a tile-only estimate hides.
