Tile Installation in Orange County, California

No. Grout is porous and passes both liquid water and vapor over time, and tile joints are not a barrier. In a correctly built shower a continuous waterproof membrane sits directly behind the tile and returns water to the drain. The tile and grout are the wear surface, not the waterproofing.

All four common families work when installed as complete systems: sheet membranes like Kerdi, liquid membranes like RedGard or Hydro Ban, bonded foam boards like Wedi, and traditional mortar beds with a pan liner. What fails is mixing brands, skipping corner reinforcement, or applying a liquid membrane below its required thickness.

It is the percentage of the tile back in actual contact with mortar. ANSI requires 95 percent in wet areas and exteriors and 80 percent in dry interiors, with full support at corners and edges. Voids hold water in showers and become the origin point for cracked tile on floors.

Almost certainly a missing movement joint. TCNA detail EJ171 requires flexible sealant instead of grout at perimeters, changes of plane, over slab control joints and at field intervals. Rigid grout in a location that needs to move will crack again every time it is repaired until the joint is corrected.

Lippage is the height difference between adjacent tile edges. ANSI allows up to 1/32 inch plus inherent tile warpage for grout joints under 1/4 inch, and up to 1/16 inch plus warpage for wider joints. Large format tile is slightly crowned, so offset is limited to 33 percent to control it.

In Orange County we treat crack isolation as standard on slab installations. Concrete shrinks and cracks as it cures and moves seasonally with expansive clay soils, and a crack that opens will split the tile bonded above it. An ANSI A118.12 rated membrane interrupts that transfer for a small fraction of the replacement cost.

Use it where staining or chemical exposure is the real risk: kitchen backsplashes behind a range, steam showers, laundry rooms and glass installations. It never needs sealing and holds color permanently. It costs several times more, demands fast disciplined cleanup, and can lock residue into textured tile faces.

Yes, and twice at installation. An impregnating sealer goes on before grouting to keep pigment out of the stone, and again after cleanup. Reseal roughly annually in wet areas and every two to five years on interior floors. Sealing prevents staining but does not prevent acid etching on marble or travertine.

Three ways. A matching bullnose piece where the line still produces one. A mitered outside corner where both tiles are cut at 45 degrees so the faces meet cleanly. Or a metal profile such as a Schluter Jolly or Quadec, set into the mortar as the tile goes in. A raw cut edge is never acceptable.

Plan on the mortar curing before grouting, usually 24 hours, then a further period after grouting before water exposure. Cementitious grout typically needs 72 hours, epoxy about 24, and urethane grouts often require a full week before the shower is used. Follow the specific product instruction, not a general rule.

Sometimes on walls and floors where the existing tile is fully bonded, flat and clean, and the height gain is acceptable. It is never appropriate in a shower, because you would be building over an unknown or absent waterproofing layer. In showers, we take everything back to the studs.

It is filling the finished shower pan with water to just below the curb for 24 hours and confirming the level has not dropped and nothing below has stained. It is the only way to prove the waterproofing is continuous while it is still accessible. We do it on every shower and photograph the result.

Around 10 percent for a straight grid layout in a simple room, 15 percent for a diagonal or offset pattern, and 20 percent or more for herringbone, chevron and rooms with many angles. Order all of it in one lot up front, because dye lots vary and a matching reorder six weeks later is unlikely.

Yes, with attention to stiffness. The floor system needs deflection no greater than L over 360 for ceramic and porcelain and L over 720 for natural stone, which sometimes means adding a layer of plywood or sistering joists. Then a cement backer board or membrane goes over the plywood before tile.

Typically 7 to 12 working days from demolition to walkthrough for a standard shower, and longer for curbless entries, multiple niches or intricate patterns. The schedule includes fixed waiting periods that cannot be compressed: membrane cure, a 24 hour flood test, mortar cure and grout cure before use.
