What does a flooring inspector do?

A certified flooring inspector performs an independent on-site evaluation of your flooring system to identify installation defects, product failures, moisture damage, and subfloor issues. The inspection includes technical measurements, moisture testing, photo documentation, and a professional written report summarizing findings and recommendations.

How much does a flooring inspection cost in Southern California?

My Floor Inspection offers three service tiers: Standard Flooring Inspection starting at $550, Advanced Flooring & Tile Inspection starting at $650, and NWFA Forensic Hardwood Inspection starting at $750. Pricing may vary based on travel distance, complexity, and reporting requirements.

Do I need a flooring inspection for an insurance claim?

Yes. A certified independent flooring inspection is often required to support insurance claims involving flooring damage. The inspector provides objective, evidence-based documentation that can be submitted to your insurance company to support your claim. My Floor Inspection provides forensic-grade inspection reports suitable for insurance and legal proceedings.

What certifications does My Floor Inspection hold?

My Floor Inspection holds certifications from the National Wood Flooring Association (NWFA #CP2416122), Flooring Consultants and Inspection Training Services (FCITS #2031), North American Laminate Flooring Association (NALFA), International Floor Covering Inspection Institute (IFCII), and is a CFI University Graduate conducting ASTM-standards-based testing.

Primary service cities include Los Angeles, Beverly Hills, Santa Monica, Malibu, Pasadena, Long Beach, Irvine, Newport Beach, and more.

Why is my hardwood floor cupping?

Hardwood floor cupping — where the edges of boards rise higher than the center — is almost always caused by a moisture imbalance. The bottom of the boards is absorbing more moisture than the top, causing them to cup upward. Common causes include subfloor moisture, plumbing leaks, high humidity, or improper acclimation during installation. A certified inspection can identify the source and document the damage.

Why is my SPC or LVP floor separating or buckling?

SPC (Stone Plastic Composite) and LVP (Luxury Vinyl Plank) floors can separate or buckle due to thermal expansion from temperature fluctuations, insufficient expansion gaps at walls, improper installation on uneven subfloors, or excessive direct sunlight. A flooring inspection will assess the installation quality, substrate conditions, and product behavior to determine the root cause.

What causes hollow tile sounds?

Hollow tile sounds (called 'drummy tile') indicate a loss of bond between the tile and the adhesive or substrate beneath. This is typically caused by improper thinset coverage during installation, substrate movement, subfloor deflection, or moisture intrusion beneath the tile. Hollow or drummy tile is a significant installation defect and should be evaluated by a certified tile inspector.

Tile Moisture Problems

Last Updated: July 2026By Efi Eylor · NWFA Certified Inspector

While ceramic and porcelain tile are inherently water-resistant, the tile installation system — thinset, grout, substrate, and waterproofing — is vulnerable to moisture problems. Water that penetrates beneath tiles can cause bond failure, efflorescence, mold growth, and progressive substrate damage.

Key Takeaways

Efflorescence — white mineral deposits on grout and tile — indicates moisture migrating through the substrate
Moisture beneath tiles destroys the thinset bond, leading to hollow and loose tiles
In showers and wet areas, waterproofing membrane failures allow water into walls and subfloors
Concrete slab moisture vapor can affect tile installations bonded directly to the slab
A certified inspection uses moisture meters, visual assessment, and destructive testing to identify moisture paths

Frequently Asked Questions

Is hollow tile always a defect?

Not always — some hollow sound at tile edges is acceptable. But widespread hollow tile or hollow sounds at tile centers indicate a significant installation defect under ANSI standards.

How much does a tile inspection cost?

Our Advanced Flooring & Tile Inspection starts at $650 and includes substrate evaluation, thinset coverage assessment, and a detailed written report.
