How much does paver cleaning and sealing cost?

Professional paver cleaning and sealing in North Jersey costs $3-6 per square foot for combined service. A typical 500 sqft patio runs $1,500-3,000, while a 1,000 sqft area costs $3,000-6,000. Pricing depends on paver condition (heavy staining adds $0.50-1.00/sqft), size, sealer type, and repairs needed. Randy Seal Coating provides free quotes with transparent pricing and no hidden fees.

How long does the paver cleaning and sealing process take?

Professional service takes 2-3 days total. Day 1 includes cleaning, stain removal, and power washing (4-6 hours). Pavers must dry 24-48 hours. Day 2 or 3 includes joint sand replacement and sealer application (3-4 hours). Wait 24-48 hours before foot traffic and 72 hours before vehicle traffic. Full cure takes 7-14 days.

Can I clean and seal pavers myself or should I hire a professional?

DIY is possible for small areas under 500 sqft if you have experience and equipment. However, professional service provides better value for most homeowners. Common DIY mistakes include:

• Excessive pressure damaging paver surface ($2,000-5,000 repair)
• Inadequate drying causing white sealer haze ($1,500-3,000 fix)
• Uneven application creating streaks
• Wrong sealer for climate causing premature failure

Professional service offers commercial equipment, 20+ years expertise, 2-3 year warranty, and guaranteed results for $3-6/sqft.

How long does paver sealer last in North Jersey?

Paver sealer lasts 2-4 years average in North Jersey, with premium commercial sealers lasting up to 5 years. North Jersey's harsh winters with 40-50 freeze-thaw cycles reduce lifespan compared to milder regions. Signs it's time to reseal: water no longer beads, color fading returns, increased staining, and joint sand erosion. We recommend resealing every 2-3 years for optimal protection.

What's the best time of year to seal pavers in North Jersey?

Spring (April-June) and fall (September-October) are optimal. These seasons offer ideal temperatures (50-75°F) and lower humidity. May and September are perfect months. Summer works but brings high heat and storms. Winter (November-March) must be avoided as cold prevents proper curing and freezing damages fresh applications. Complete before first frost.

Do pavers need to be cleaned before sealing?

Yes, thorough cleaning is absolutely essential. Dirt, stains, efflorescence (white salt deposits), and organic matter must be removed or they'll be sealed underneath. Process includes power washing at 2500-3500 PSI, treating specific stains, and efflorescence removal. After cleaning, pavers must dry 24-48 hours. Sealing over moisture causes white haze, cloudiness, and sealer failure.

What are common mistakes when cleaning and sealing pavers?

The 10 most damaging mistakes:

1. Using excessive pressure (over 3500 PSI) damaging surface
2. Inadequate drying time causing sealer haze
3. Sealing over efflorescence which continues underneath
4. Wrong sealer type for climate
5. Uneven application creating streaks
6. Ignoring weather conditions
7. Not replacing joint sand before sealing
8. Using cheap low-quality sealers
9. Working in direct hot sun
10. Skipping stain pre-treatment

These mistakes cost $1,500-5,000 to fix through sealer stripping and reapplication.

What's the difference between water-based and solvent-based paver sealer?

Water-based sealers: Eco-friendly, low odor, easy application, natural/satin finish, pavers breathe, cost less, last 2-3 years. Best for patios and walkways.

Solvent-based sealers: Penetrate deeper, wet look or natural finish options, superior freeze-thaw protection, better stain resistance, enhance colors more, cost more, last 3-5 years. Best for driveways and high-traffic areas. For North Jersey winters, we recommend solvent-based for driveways due to better freeze protection.

How long after cleaning should I wait before sealing pavers?

Wait minimum 24-48 hours after cleaning. In humid conditions or shade, wait 48-72 hours. Test with plastic sheeting taped over pavers overnight - no condensation should appear in morning. Both paver surface AND joint sand must be completely dry. Sealing over moisture causes white haze, cloudiness, and premature failure. Check 48-hour weather forecast - avoid if rain expected.

Will sealing pavers prevent weeds and ants between them?

Yes, significantly reduces but doesn't eliminate completely. Process includes removing all weeds, installing polymeric sand which hardens when activated, and sealing which locks sand in place. This prevents most weed germination and makes it harder for ants to excavate. However, some opportunistic weeds may grow on top if organic matter accumulates. For maximum prevention, combine sealing with polymeric sand and annual cleaning.

Does sealing pavers make them slippery when wet?

High-gloss wet-look sealers can make smooth pavers slightly more slippery when wet, but textured pavers maintain good traction. For pool decks, walkways, stairs, and ramps, choose natural or satin finish sealers which preserve texture. Anti-slip additives can be added to any sealer for maximum safety. North Jersey's freeze-thaw climate actually makes sealed pavers safer in winter because sealer prevents ice formation in paver pores.

Can I seal pavers in sections or must I do the entire area at once?

While technically possible, it's strongly not recommended. You'll see visible lines where old and new sealer meet. Sealer ages and fades over time, so new sealer looks dramatically different even with identical product. If you must seal in sections due to budget, choose natural break lines like steps or borders. For best appearance, seal entire connected area at once. Randy Seal Coating offers flexible payment plans to make complete sealing affordable.
