Certified Flooring Inspection
Certified Tile & Stone Floor Inspection in Southern California
Professional tile and stone flooring inspection including hollow tile mapping, crack analysis, thinset coverage assessment, and movement joint compliance — documented against TCNA and ANSI A108 standards.
About This Service
Tile installation failures — hollow tile, cracking, grout joint failure, and delamination — are among the most technically complex flooring disputes. Industry standards (TCNA Handbook, ANSI A108 series) establish very specific requirements for thinset coverage, substrate preparation, movement joint placement, and deflection limits that are frequently violated in residential and commercial construction.
My Floor Inspection provides Advanced Tile and Stone Inspections throughout Southern California using systematic tap testing, thinset coverage assessment, and substrate analysis — producing forensic reports that clearly document standards violations and their role in the observed failure. We serve residential and commercial properties in Los Angeles, Orange County, San Diego, and surrounding areas.
What This Inspection Covers
Issues & Disputes We Resolve
Why It Matters
Hollow tile and cracking rarely appear in isolation — they indicate systemic installation deficiencies that will continue to worsen. Contractors frequently deny responsibility and blame tile quality, subfloor conditions, or building movement. A standards-based inspection report with TCNA and ANSI references provides the objective evidence needed to resolve disputes.
Frequently Asked Questions
What is the industry standard for tile thinset coverage?
ANSI A108.5 specifies a minimum of 80% mortar contact for interior residential tile and 95% for wet areas, exteriors, large-format tile (15" or larger), or heavy load areas. These standards are the benchmark for our thinset coverage assessments.
Can I inspect tile without removing it?
Yes. Systematic tap testing identifies hollow tile without destructive investigation. When coverage documentation is required for forensic purposes, core sampling or examination at existing grout joints may be performed.
Related Flooring Issues
Ceramic & Porcelain Tile / Stone
Tile cracking is caused by movement beneath the tile — subfloor deflection, concrete slab cracking, thermal stress, or inadequate bond — that exceeds the tile's tensile strength.

Hollow tile sounds — a drum-like resonance when tapping — indicate that the tile has lost bond with the substrate below. This signals installation deficiency, moisture-induced debonding, or structural movement.

Moisture beneath flooring — from concrete vapor emission, plumbing leaks, or groundwater — is the single most common cause of flooring failures. Professional ASTM-certified moisture testing establishes the source, magnitude, and impact.
