Complete Paver Restoration on Long Island
Your pavers were a significant investment — often $15,000-$50,000+ for a driveway, patio, or pool deck. When properly maintained, pavers add tremendous value and curb appeal to your Long Island home. When neglected, they become a weed-filled, shifting, faded eyesore that actually detracts from your property.
Best Power Wash LI's paver wash, sand, and seal service is the most comprehensive paver restoration program on Long Island. We don't just pressure wash and walk away — we restore your pavers to better-than-new condition and protect them for years to come.
Our 3-Step Paver Restoration Process
Step 1: Deep Clean
We pressure wash every paver surface using commercial-grade equipment and surface cleaners. This removes:
- Embedded dirt and organic staining
- Algae, mold, and mildew
- Efflorescence (white mineral deposits)
- Old degraded sealant
- All existing joint sand — down to the base
- Weed roots and organic debris in joints
- Ant colonies and insect nests in joints
This step is critical. Sealing over dirty pavers or deteriorated sand locks in problems instead of solving them. We clean every joint, every surface, and every edge before moving forward.
Step 2: Re-Sand with Polymeric Sand
Once pavers are clean and completely dry (we typically schedule sanding 24-48 hours after washing, weather permitting), we fill all joints with premium polymeric sand.
What Is Polymeric Sand?
Polymeric sand is an engineered jointing sand that contains polymers (binding agents) that activate when wetted. Once activated and cured, the sand forms a firm yet flexible joint that locks pavers together while allowing necessary thermal expansion.
Polymeric sand is categorically superior to regular play sand, mason sand, or basic joint sand. Here's why:
- Weed resistance — the hardened joint prevents weed seeds from germinating
- Ant prevention — ants cannot tunnel through properly cured polymeric sand
- Washout resistance — rain doesn't erode polymeric sand the way it does regular sand
- Paver stability — filled joints prevent pavers from shifting, rocking, and settling
- Clean appearance — consistent color fills every joint evenly
We use only top-tier polymeric sand brands designed for Long Island's freeze-thaw climate. Cheap polymeric sand cracks and fails — we don't cut corners here.
Polymeric Sand Installation Process
The sand is swept into all joints, compacted with a plate compactor, swept again to ensure complete fill, and then activated with a controlled misting of water. The activation process is precise — too little water and the polymers don't bind; too much and the sand washes out before curing. This is where professional expertise matters most.
Step 3: Professional-Grade Sealer Application
After the polymeric sand has cured (typically 24 hours), we apply a professional-grade paver sealer that provides UV protection, stain resistance, color enhancement, and moisture barrier properties.
Wet-Look vs. Matte Sealer: Which Is Right for You?
Wet-Look (Glossy) Sealer
- Creates a rich, glossy sheen that dramatically enhances paver color
- Makes pavers look permanently "just rained on"
- Best for: patios, pool decks, entertainment areas, decorative installations
- Shows the full color depth of your pavers
- More visible enhancement — guests will notice immediately
- May need reapplication every 2-3 years depending on traffic
Natural-Look (Matte) Sealer
- Provides all protective benefits without changing appearance
- Pavers look clean and natural — no glossy sheen
- Best for: driveways, walkways, traditional/rustic designs
- Subtler enhancement — protects without drawing attention
- Less maintenance — doesn't show wear patterns as readily
- Longer intervals between reapplication (3-5 years)

Common Paver Problems We Solve
Weed Growth Between Pavers
The #1 complaint from Long Island paver owners. Weeds grow when joint sand erodes, leaving space for seeds. Our process removes all existing sand and weed roots, refills with polymeric sand, and seals — eliminating the weed pathway entirely.
Ant Hills in Paver Joints
Ants love the loose sand between pavers. They excavate joints, creating mounds and destabilizing the surface. Polymeric sand's hardened bond prevents ant colonization. No loose sand = no ant habitat.
Shifting & Settling Pavers
When joint sand washes out, pavers lose their interlock and begin to shift, rock, and settle unevenly. Our process restores proper joint fill, re-compacts the surface, and seals everything in place. Note: if pavers have severely settled due to base failure, base repair may be needed before our wash/sand/seal process.
Faded & Discolored Pavers
UV exposure, chemical runoff, and organic staining fade paver color over time. Professional cleaning removes surface staining, and sealer (especially wet-look) dramatically revives original color vibrancy.
Efflorescence (White Haze)
Those white, chalky deposits on pavers are mineral salts leaching from the concrete. Our cleaning process removes existing efflorescence, and proper sealing reduces future occurrences by limiting moisture penetration.
Oil & Grease Stains
Driveway pavers catch oil drips, transmission fluid, and other automotive stains. Our pre-treatment with commercial degreasers removes most staining, and sealer makes future spills easier to clean before they penetrate.
Water Drainage Issues
Pooling water on or around your pavers is a warning sign. Poor drainage erodes base material from underneath, causes frost heaving in winter, accelerates efflorescence, and creates mosquito breeding habitat in summer. Common drainage problems include: pavers that have settled and lost their original slope, blocked drainage channels filled with debris and polymeric sand overflow, inadequate original grading, and downspout discharge eroding adjacent base material.
Our cleaning process addresses surface drainage by ensuring joints are properly filled and water can flow as designed. For more serious drainage problems — re-grading, drain installation, or base repair — see our paver repair & restoration service.
Paver Color Restoration
UV radiation from Long Island's sun bleaches paver pigment over time, leaving surfaces dull and washed out. Environmental staining from leaves, pine needles, and organic growth adds discoloration on top of the fading. Our process addresses color loss in two ways: deep cleaning removes all surface staining and discoloration, revealing the original pigment underneath. Then our professional-grade sealer — especially the wet-look option — dramatically enhances and protects the remaining color, making pavers look richer and more vibrant than they have in years.
For pavers with significant UV damage, the sealed color enhancement can make a 10-year-old installation look nearly new. The sealer also provides ongoing UV protection to slow future fading.
Need Structural Paver Repair?
Our wash, sand, and seal service restores the appearance and protection of structurally sound paver installations. If your pavers have significant settling, shifting, cracking, or drainage problems, our paver repair & restoration service addresses the structural issues first — then we finish with wash, sand, and seal for a complete transformation.
Paver Types We Service
- Concrete pavers — the most common type on Long Island (Cambridge, Belgard, Nicolock, Techo-Bloc, EP Henry)
- Natural stone pavers — bluestone, travertine, granite, limestone, sandstone
- Brick pavers — clay brick in traditional and herringbone patterns
- Porcelain pavers — newer premium pavers with specific sealing requirements
- Permeable pavers — eco-friendly pavers with specialized joint treatment
What Affects Paver Sealing Cost?
- Area size — measured in square footage
- Paver condition — heavy staining, efflorescence, or old sealant adds cleaning time
- Joint condition — severely eroded joints need more polymeric sand
- Sealer type — wet-look and matte sealers are priced similarly; specialty sealers may differ
- Access — backyard patios vs. front driveways
- Pattern complexity — intricate patterns with narrow joints take more time to sand
Most residential paver projects on Long Island range from $1,000-$5,000+ for the complete wash, sand, and seal process. We provide detailed, itemized estimates so you know exactly what you're getting.
How Long Does Paver Sealing Last?
Professional paver sealing typically lasts 3-5 years depending on traffic, UV exposure, and maintenance. We recommend re-sealing before protection fully wears off — maintaining the seal is easier and cheaper than starting from scratch with severely deteriorated joints.
Paver Maintenance Tips
- Sweep regularly to prevent organic debris from accumulating
- Address oil spills quickly with kitty litter and mild cleaner
- Remove weeds promptly if any manage to sprout
- Avoid using de-icing salts directly on sealed pavers — use sand for traction instead
- Don't use muriatic acid or harsh chemicals on sealed pavers
- Schedule re-sealing every 3-5 years to maintain protection
