Repair makes sense when damage is localized, the substrate is sound and matching material exists. Replacement becomes more credible when tiles repeatedly crack, moisture reaches the assembly, bond failure is widespread or access and matching dominate cost. Do not decide from appearance alone. Document the pattern, water exposure, movement and adjacent finishes before choosing a scope.
Map the failure pattern
Mark cracked, loose, hollow, stained or displaced areas and note when symptoms appear. One impact chip differs from a repeating crack across several tiles. Ask whether the observation proves a cause or only identifies where investigation should begin. Retain loose pieces and photographs.
Investigate moisture before closing
Leaks at plumbing, exterior openings or wet-area transitions must be corrected before finish work. Determine whether the substrate and adjacent materials are dry and sound. A new tile surface is not a waterproofing diagnosis. Separate source correction, drying, substrate repair and finish replacement.
Evaluate substrate and movement
Tile depends on the assembly below it. Document backer, mortar bed, concrete, wood framing, deflection concerns and movement joints. Use a limited opening where necessary. Replacement over the same unresolved movement can repeat the failure even with a stronger tile.
Decide the matching boundary
Compare retained samples under normal light. Color, size, calibration, stone variation and grout age can make an isolated patch visible. Price the minimum technical repair and broader aesthetic boundary separately. Do not expand work without showing why matching or access requires it.
Define wet-area rebuilding
For showers and other wet areas, specify the waterproofing system, drain connection, penetrations, transitions, flood or other applicable tests, cure times and inspection path. Tile and grout are finish layers, not substitutes for a complete water-management assembly.
Include demolition and protection
State dust control, debris route, fixture removal, occupied-area protection and what remains usable. Define demolition limits and how adjacent cabinets, glass, plumbing and floors are protected. Unknown damage needs a written stop point and approval process.
Verify contractor and permits
Use Washington L&I's Verify tool to check the contracting business and any required trade professionals. Confirm permits for structural, plumbing or other regulated changes. Assign inspections and closeout records rather than assuming a finish contractor handles every trade.
Test and close out
Inspect alignment, lippage, joints, edges, transitions, sealant and cleanup. Operate affected plumbing and retain waterproofing, setting-material and grout information, permits, photographs and warranties. Record cure and maintenance instructions before normal use.
Compare complete proposals
Compare cause investigation, demolition, substrate, waterproofing, tile or stone, layout, grout, transitions, plumbing, permits, protection, disposal and warranty. Use quantities and written rates for uncertain work. The best choice follows evidence, not a generic price or age rule.
Account for access and schedule
Selective repair may require careful removal, matching and multiple cure periods, while replacement affects a larger occupied area. Compare protection, fixture removal, debris route, material lead time and return-to-use rather than assuming the smaller visible area is always easier.
Preserve future repair information
Keep extra tile or stone, batch and product data, layout photographs, waterproofing and setting-material records, color references and care instructions. These records make later maintenance possible without repeating the entire investigation.
Frequently asked questions
When is tile repair reasonable?
When cause is corrected, substrate is sound, matching material exists and the repaired assembly can be tested.
When is replacement more credible?
When moisture, movement, bond failure or damage extends beyond a reliable local boundary.
Is tile or grout waterproof?
No. Wet areas need a defined water-management assembly behind or below the finish.
How should matching be handled?
Compare retained samples in normal light and price technical and visual boundaries separately.
Does tile work need permits?
Related structural, plumbing or electrical work may require permits; confirm the Tacoma address and scope.
What belongs in closeout?
Keep approvals, photos, product data, extra tile, care instructions, warranties and punch-list evidence.
