Paver Cleaning & Sealing in St. Louis
Restore the original beauty of your pavers and protect them from Missouri's freeze-thaw cycles, weed growth, and staining.
Professional Paver Cleaning & Sealing
Paver cleaning and sealing is the single most effective way to protect your hardscaping investment and keep it looking like the day it was installed. Over time, St. Louis weather breaks down joint sand, encourages moss and weed growth, and causes color fading that makes even premium pavers look neglected.
Green Operations provides complete paver restoration services for patios, driveways, walkways, and pool decks across the St. Louis metro area. With 20+ years of hardscaping experience, we understand the materials, sealers, and techniques that deliver lasting results in Missouri's climate.
Most paver installations need cleaning and resealing every 2 to 3 years. A properly maintained paver surface can last 25 years or more without needing replacement, making regular maintenance one of the best returns on any home improvement investment.
Why Clean & Seal Your Pavers?
Left untreated, even the best pavers deteriorate. Here are the most common problems we see on St. Louis properties.
Weed & Moss Growth
When joint sand washes out, weeds and moss take root between pavers. This forces pavers apart, creating uneven surfaces and tripping hazards.
Color Fading
UV exposure and Missouri rain strip away the surface color of unsealed pavers. What started as rich reds, browns, or grays fades to a washed-out, chalky appearance.
Joint Sand Loss
Heavy rain and pressure from foot traffic wash polymeric sand from joints. Without sand, pavers shift, settle unevenly, and lose their interlocking strength.
Oil & Rust Stains
Driveways absorb oil drips. Patio pavers pick up rust from furniture legs. Leaf tannins leave dark outlines. Once embedded, these stains are difficult to remove without professional equipment.
Our Cleaning & Sealing Process
Every project follows a proven 4-step process that restores your pavers and locks in protection for years to come.
Inspection & Prep
We assess the paver condition, identify stains, check joint integrity, and clear the area of furniture, planters, and debris. We also protect adjacent landscaping and surfaces.
Pressure Washing
Using commercial-grade equipment at the right PSI for your paver type, we remove dirt, algae, moss, efflorescence, and stains. We never use pressure levels that damage the paver face.
Joint Sand Replacement
After cleaning, we sweep new polymeric sand into all joints and activate it with a controlled mist. This locks pavers in place and prevents weed regrowth, ant hills, and sand washout.
Sealer Application
Once the surface is completely dry (typically 24-48 hours), we apply a professional-grade sealer in even coats using low-pressure sprayers. Two coats are standard for maximum protection.
Types of Paver Sealers
We carry multiple sealer options so you get the exact look and level of protection you want.
Wet Look Sealer
Enhances color and adds a subtle sheen that makes pavers look freshly rained on. This is the most popular choice for patios and pool decks where homeowners want rich, saturated color. Highlights the natural tones and patterns in your pavers.
Natural Look Sealer
Provides full protection without changing the paver's appearance. Ideal for driveways and walkways where you want a clean, matte finish. The sealer penetrates the surface without leaving a visible film, so your pavers look exactly the same -- just protected.
Joint Stabilizing Sealer
Combines surface protection with extra joint-hardening properties. This sealer bonds polymeric sand even more firmly, which is ideal for high-traffic areas like driveways and commercial walkways where joint erosion is the primary concern.
When to Clean & Seal Your Pavers
Most hardscaping professionals recommend cleaning and resealing pavers every 2 to 3 years. In St. Louis, where freeze-thaw cycles, humid summers, and heavy rains are all normal, staying on that schedule prevents small problems from becoming expensive repairs.
Signs It's Time
- Water no longer beads on the paver surface -- it soaks in immediately
- Weeds or moss are growing between joints
- Colors look faded, chalky, or inconsistent compared to when installed
- Joint sand is visibly missing or washed below the paver surface
- Ant hills or insect activity in the joints
- Stains from oil, leaves, or rust that won't come off with a garden hose
The best time to schedule paver cleaning in St. Louis is late spring through early fall, when temperatures stay above 50 degrees F for at least 24 hours after sealer application. We typically book 2-3 weeks out during peak season, so planning ahead is recommended.
