Maintenance & Warranty | Natural Stone

Natural stone, including marble, granite, limestone, and slate, is prized for its beauty and durability in architectural and design applications. However, its longevity depends on proper maintenance and understanding warranty provisions. This guide outlines best practices for care and key considerations for warranties to protect your investment.

Maintenance of Natural Stone

1. Daily Care
Cleaning: Use pH-neutral cleaners to avoid etching. Avoid acidic substances (vinegar, citrus) and abrasive tools.
Spills: Wipe immediately, especially with liquids like wine, coffee, or oils to prevent staining.
Surfaces: Use coasters under drinks and trivets for hot dishes to prevent thermal shock or scratches.

2. Periodic Maintenance
Sealing: Critical for porous stones (e.g., marble, limestone). Frequency varies:
Granite: Every 1–2 years.
Marble: Every 6–12 months.
Test sealant effectiveness by dripping water; if it beads, the seal is intact.
Professional Services: Annual deep cleaning and inspection by certified technicians.

3. Preventive Measures
Protection: Use mats at entryways to reduce abrasive dirt. Avoid dragging heavy objects.
Environment: Control humidity and temperature to prevent expansion/contraction cracks.
Foot Traffic: High-traffic areas may require more frequent sealing or protective coatings.

4. Repair & Restoration
Etching/Stains: Use polishing powders or poultices. For deep stains, consult professionals.
Cracks/Chipping: Epoxy resins or stone fillers for minor damage. Severe issues may require replacement.
Refinishing: Honing (matte finish) or polishing (glossy) to restore aesthetics.

Warranty Considerations for Natural Stone

1. Types of Warranties
Material Warranty: Covers defects in the stone (e.g., fissures, discoloration). Typically offered by manufacturers.
Installation Warranty: Covers workmanship (e.g., improper sealing, adhesion). Usually provided by contractors.
Extended Warranties: Optional coverage for specific risks (e.g., staining).

2. Coverage Details
Inclusions: Defects in natural composition, manufacturing errors, or installation failures.
Exclusions: Damage from improper maintenance (e.g., using acidic cleaners).
Accidents, neglect, or natural wear (e.g., gradual polishing loss).
Structural issues unrelated to the stone (e.g., building settling).

3. Duration & Limitations
Material Warranties: Range from 1 year to lifetime, often prorated over time.
Installation Warranties: Typically 1–5 years.
Transferability: Some warranties void if property ownership changes; check terms.

4. Claims Process
Documentation: Keep purchase receipts, installation records, and maintenance logs.
Procedures: Notify provider promptly; expect inspections to validate claims.
Disputes: Third-party assessments may be required if coverage is contested.

Best Practices for Warranty Compliance

Follow Guidelines: Use recommended cleaners and sealants.
Professional Services: Hire certified installers for repairs to avoid voiding warranties.
Review Terms: Understand exclusions and requirements (e.g., annual sealing proofs).


Proper maintenance preserves natural stone’s elegance, while understanding warranties ensures protection against unforeseen issues. Always prioritize preventive care and clarify warranty terms with providers to maximize your stone’s lifespan and value.
