What Are Sealed Pavers?
Sealed pavers are concrete, brick, or stone surfaces treated with a protective sealant that boosts both their durability and visual appeal. Think of it like waxing a car – not only does it shield the surface from damage, but it also enhances its overall look.
Sealants work in two main ways: some create a glossy, polished layer on the surface, while others seep into the material’s pores for a more natural finish. Either way, the goal is the same: to guard against environmental wear and tear while extending the lifespan of the pavers. These differences in function lay the groundwork for understanding their benefits in terms of durability, appearance, and upkeep.
Durability and Protection
Materials like brick, stone, and concrete are naturally porous, which means they absorb water that can expand and cause damage when frozen. A sealant fills these pores and cracks, preventing water from seeping in – a critical feature for areas with fluctuating temperatures or heavy rainfall. Sealed pavers are also better equipped to handle freeze-thaw cycles, salt, and other environmental challenges. This layer of protection is especially useful in outdoor spaces exposed to irrigation, where unchecked moisture can lead to serious wear and tear.
In addition to water resistance, sealing helps stabilize the sand between the pavers. By hardening the joint sand, sealants reduce washout during heavy rain or pressure washing. This not only prevents weed growth, mold, and algae but also keeps ants from nesting in the gaps.
Appearance Benefits
Sealants can bring out the pavers’ natural colors, giving them a vibrant, polished look. Whether you prefer a glossy finish that mimics a wet surface or a matte finish for a more understated appearance, sealants can deliver. Many sealers also include UV protection, which helps prevent fading and keeps the pavers looking fresh over time.
Maintenance Requirements
One of the standout perks of sealed pavers is how easy they are to maintain. Cleaning usually involves just soap, water, and a medium-bristle broom to sweep away dirt and debris. The protective layer also makes it simple to wash off dirt, grease, and grime without leaving permanent stains. Spills stay on the surface, making cleanup quick and hassle-free.
Routine upkeep includes sweeping, occasional pressure washing, and spot-cleaning. Using high-quality jointing sand along with a good sealer helps minimize weed and mildew growth. Resealing every 2 to 3 years keeps the pavers in top condition. Compared to unsealed pavers, this maintenance routine is far less demanding, as we’ll explore later.
What Are Unsealed Pavers?
Unsealed pavers are made from materials like concrete, brick, or natural stone and are left untreated, exposing their natural pores. Unlike sealed pavers, which are coated with a chemical barrier to guard against moisture, UV rays, and stains, unsealed pavers rely solely on the natural characteristics of their materials. Over time, they develop a weathered appearance as they age naturally.
Natural Look
Unsealed pavers maintain their raw, organic charm without the sheen of a sealant. Their matte finish and earthy tones create a rustic, timeless vibe, making them a perfect fit for traditional or cottage-style outdoor spaces. As the years go by, these pavers develop a weathered patina that many homeowners find visually appealing.
Lower Upfront Costs
One of the main perks of unsealed pavers is their lower initial cost. Skipping the sealing process can save money, especially on larger projects. However, while the upfront savings are attractive, they may be offset over time by the need for more frequent cleanings and occasional repairs.
Durability and Maintenance Challenges
The porous nature of unsealed pavers makes them more susceptible to stains from oil, grease, and other substances. Water can seep into the material, encouraging the growth of mold, moss, and mildew, which can make surfaces slippery and even lead to cracking during freeze-thaw cycles. Additionally, without a sealant to stabilize the sand between the pavers, heavy rain or pressure washing can wash the sand away, causing the pavers to shift and creating uneven surfaces that might require expensive repairs or even full reinstallation.
To maintain unsealed pavers, regular upkeep is crucial. Sweeping and rinsing them off can help clear away debris, while quickly addressing spills or stains can prevent permanent damage. Homeowners should also periodically remove moss, mildew, or weeds from the joints to keep their outdoor areas looking clean and safe.
Next, we’ll compare sealed and unsealed pavers, focusing on durability, maintenance, and cost.

Sealed vs. Unsealed Pavers: Direct Comparison
When deciding between sealed and unsealed pavers, it’s essential to weigh how each option performs in areas that matter most to homeowners, such as durability, maintenance, and cost.
Durability and Lifespan
Sealed pavers come with a protective coating that acts as a barrier against environmental damage, significantly extending their lifespan. This coating prevents water from seeping into the material, which is especially important in regions with freeze-thaw cycles. Without this protection, water can freeze and expand, leading to cracks that compromise the entire installation.
Additionally, sealed pavers resist damage from salt exposure, whether it’s from de-icing salts in winter or coastal air. On the other hand, unsealed pavers absorb salts, which can cause surface deterioration and discoloration over time.
| Factor | Sealed Pavers | Unsealed Pavers |
|---|---|---|
| Moisture Protection | Prevents water seepage; resists freeze-thaw damage | Absorbs water; prone to cracking in freeze-thaw cycles |
| UV Protection | Resists fading from sunlight | Colors fade gradually from UV exposure |
| Stain Resistance | Shields against oil, grease, and food spills | Stains penetrate deeply, making removal difficult |
| Joint Stability | Joint sand remains intact during rain | Sand washes away, causing pavers to shift |
| Overall Lifespan | Lasts longer due to protective barrier | Requires more repairs or replacements sooner |
One of the most noticeable differences is in stain resistance. Sealed pavers have a less porous surface, making it harder for oil, grease, rust, or organic debris to penetrate. This means spills can be easily wiped away. Unsealed pavers, however, absorb stains deeply, making them harder – if not impossible – to remove.
Next, let’s explore how these durability benefits translate into day-to-day maintenance.
Maintenance and Cleaning
The difference in maintenance between sealed and unsealed pavers is striking. Sealed pavers are much easier to clean. The protective sealant prevents dirt and grime from embedding into the surface, so regular cleaning requires minimal effort. A quick sweep or rinse is often enough.
Because sealed pavers maintain joint stability, they require less frequent upkeep. In contrast, unsealed pavers demand more attention. Their porous surface allows dirt and stains to settle in, requiring more aggressive cleaning techniques. Everyday spills – like barbecue grease, suntan lotion, or automotive fluids – can leave permanent marks if not addressed immediately.
Sealed pavers also help reduce weed growth and moss accumulation. Water penetration in unsealed pavers creates an ideal environment for mold, mildew, and moss, especially in humid climates. Unsealed pavers are also more likely to attract pests like ants, which can nest in the joints and beneath the surface.
Seasonal maintenance is another area where sealed pavers shine. They require minimal weeding and moss removal, while unsealed pavers often need constant attention to prevent these issues from becoming both unsightly and damaging. During heavy rains, sealed pavers retain their joint stability, whereas unsealed pavers lose sand, leading to uneven surfaces that require regular refilling and leveling.
Cost Comparison
The upfront and long-term costs of sealed and unsealed pavers vary significantly. Unsealed pavers have a lower initial cost since they skip the sealing process entirely. For larger projects, this can result in meaningful savings during installation.
However, sealed pavers come with additional upfront expenses. Applying the sealant adds to the installation cost, and maintaining the protective barrier requires resealing every two to three years. Factors like climate, sun exposure, foot traffic, and the quality of the sealant can influence how often resealing is necessary. For example, areas with intense sun or harsh weather may require more frequent resealing.
While unsealed pavers avoid resealing costs, they often incur other expenses over time. Frequent cleaning, stain removal treatments, and earlier repairs or replacements can offset the initial savings. If sand washes out and pavers shift, the cost of leveling and reinstallation can be substantial. Plus, the labor and time required for ongoing maintenance add to the overall expense.
In harsh climates with extreme weather conditions – like freeze-thaw cycles, high humidity, or heavy rainfall – sealed pavers tend to offer better long-term value despite their higher upfront cost. They prevent costly damage and reduce maintenance needs. In more temperate climates, the cost gap between sealed and unsealed pavers narrows, though sealed pavers still provide advantages in appearance and reduced upkeep.
For high-traffic areas such as driveways, outdoor dining spaces, or barbecue zones, the added protection and ease of maintenance that sealed pavers offer often justify the extra investment. However, for low-traffic decorative pathways or garden areas, unsealed pavers might suffice without major issues.
How Climate Affects Your Paver Choice
Climate plays a big role in determining how well your pavers will hold up and how much work they’ll require to maintain. The weather in your area directly impacts whether sealed or unsealed pavers are the better option for your outdoor spaces.
Weather Effects on Pavers
Freeze-thaw cycles can wreak havoc on pavers in colder regions. When water seeps into unsealed pavers and freezes, it expands, causing cracks and weakening the material over time. This process repeats throughout winter, slowly breaking down the pavers. Sealed pavers, on the other hand, create a barrier that keeps water out, helping them withstand these freeze-thaw cycles without damage.
Rainy and humid climates bring their own set of problems. In areas with frequent rain or high humidity, unsealed pavers absorb moisture, which can lead to mold, algae, and even weed growth in the joints. Sealed pavers repel water, reducing these moisture-related issues and cutting down on maintenance needs.
UV exposure and strong sunlight are tough on pavers too. Over time, unsealed pavers fade, losing their original color as UV rays penetrate the surface. Sealed pavers, however, come with UV-resistant properties in their sealant, helping them retain their color and vibrancy even under constant sunlight.
Coastal environments introduce another challenge: salt. Salt spray and salty air can seep into unsealed pavers, where it crystallizes and causes surface damage and structural issues. Sealed pavers provide a protective layer that keeps salt out, making them a better choice for coastal areas.
For sealed pavers, the resealing schedule depends on how harsh the local climate is. In areas with extreme weather – whether that’s intense heat, heavy humidity, or both – resealing every two years is common, though some regions might stretch that to three years. With these general climate considerations in mind, let’s look at how Southern California’s specific weather patterns affect paver performance.
Recommendations for Southern California
Southern California’s weather presents a mix of mild winters, strong sun exposure, and occasional heavy rain, calling for a tailored approach when choosing pavers. While freeze-thaw cycles aren’t a concern, the region’s year-round intense sunlight is. Unsealed pavers in this climate fade quickly, while sealed pavers retain their color longer thanks to their UV-resistant sealants.
Coastal areas face additional challenges. Salt spray and humid air, common in places like San Clemente, Huntington Beach, and Newport Beach, can damage unsealed pavers over time. Sealed pavers, with their protective barrier, are better equipped to handle these conditions, preventing salt and moisture from causing deterioration.
The occasional heavy winter rains also create potential problems. Water can seep into unsealed pavers, leading to weed growth and instability in the joints. Sealed pavers prevent water from soaking in, which helps maintain joint integrity and reduces weed issues. This is especially important in areas with poor drainage or spots prone to pooling water.
For high-traffic areas like driveways, patios, and pool decks, sealed pavers are a practical choice. They’re easier to clean, more resistant to stains, and can handle the wear and tear of daily use – ideal for busy households in Southern California.
In HOA communities across Orange County, where curb appeal and uniformity often matter, sealed pavers help maintain a polished, consistent look that meets neighborhood standards.
While Southern California’s mild climate means unsealed pavers can work in some cases, sealed pavers clearly offer added benefits. Their ability to resist UV fading, occasional water damage, and salt exposure makes them a worthwhile investment for most homeowners. Plus, with resealing needed only every two to three years, the upkeep is manageable and helps extend the life and appearance of the pavers.
Conclusion
Sealed pavers stand out for their durability, reduced maintenance needs, and ability to enhance curb appeal compared to their unsealed counterparts. While sealed pavers come with an extra cost of $0.50–$2.00 per square foot, they offer long-term benefits like better stain resistance, longer-lasting durability, and less upkeep. On the other hand, unsealed pavers might save you money upfront but require more frequent cleaning and repairs .

FAQs
How often should I reseal my pavers, and what factors affect the timing?
Pavers usually need resealing every 2–3 years, though this timeline can shift based on a few key factors. Weather exposure – like heavy rain or strong sunlight – can break down the sealant faster. Likewise, foot traffic or vehicle use can affect how long the seal lasts. The type of sealant and how well it was applied initially also influence how often resealing is required.
To maintain the appearance and durability of your pavers, make it a habit to check them for signs of wear. Look out for fading, discoloration, or water soaking into the surface. If you spot any of these, it’s probably time to reseal.
Do unsealed pavers perform better than sealed ones in certain climates or environmental conditions?
Unsealed pavers can sometimes be the smarter option, depending on your local climate or specific conditions. For instance, in regions with high humidity or frequent rainfall, their porous surface allows better water drainage. This can help minimize the risk of trapped moisture, which might otherwise lead to problems like mold or mildew. Similarly, in areas with scorching temperatures, unsealed pavers may stay cooler to the touch since they don’t retain as much heat as sealed ones.
That said, these advantages come with trade-offs. Unsealed pavers may require more maintenance and might not last as long as their sealed counterparts. To make the right decision for your outdoor space, it’s a good idea to consult with experts like Pacific Pavers, who can guide you based on your local environment and specific needs.
