Whether your travertine surrounds a swimming pool or creates an elegant outdoor living area, our multi-step cleaning and sealing process restores its appearance while helping extend the life of your investment.


What is Travertine Sealing?
Travertine sealing is the process of professionally cleaning natural stone before applying a penetrating sealer that helps reduce water absorption, staining, UV fading, algae growth, and everyday wear. In Florida, most travertine pool decks should be professionally inspected every 2-3 years to determine whether resealing is recommended.


Why Travertine Needs Sealing in Florida
Unlike concrete pavers, travertine is a natural limestone formed over thousands of years. Its beautiful pores and natural texture make it attractive—but they also allow water, dirt, sunscreen, fertilizer, oils, leaves, and organic contaminants to penetrate deep into the stone.
Without proper sealing, homeowners often notice:
- Helps reduce moisture absorption that can contribute to long-term stone deterioration.
- Minimizes staining from leaves, dirt, food spills, sunscreen, and everyday outdoor living.
- Slows UV fading to help preserve the natural color of your travertine.
- Resists mold, mildew, algae, and organic growth common in Florida’s humid climate.
- Makes routine maintenance easier by preventing contaminants from penetrating deep into the stone.
- Preserves the natural beauty and unique character of your travertine without altering its texture.
- Extends the lifespan of your travertine by reducing weather-related wear and tear.
- Helps maintain your home’s value by protecting one of your outdoor living area’s most attractive features.
- Enhances curb appeal by keeping your travertine looking clean, well-maintained, and professionally cared for.


A professional penetrating sealer dramatically slows these problems while allowing the stone to breathe naturally.
Our Travertine Cleaning & Sealing Process
