Why You Should Seal Your Paver Patio or Walkway

If you’ve invested in a beautiful paver patio or walkway for your home or business in East Tennessee, sealing it might seem like an optional extra. But the truth is, sealing your pavers is one of the best ways to protect your investment and keep your outdoor spaces looking sharp for years to come.
At Property Docktors, we specialize in designing, installing, and maintaining high-quality hardscaping and landscaping solutions throughout Lenoir City and surrounding areas—including professional paver sealing. In this post, we’ll explain the benefits of sealing, when to do it, and why it matters.
What does paver sealing do?
Paver sealing is the process of applying a specialized protective coating to the surface of your concrete or brick pavers. This clear, durable layer acts as a barrier against the most common threats to outdoor hardscapes—moisture, UV rays, stains, weeds, and wear from foot or vehicle traffic.
Unlike paint or varnish, high-quality paver sealants penetrate deep into the material, bonding with the surface to provide long-lasting protection without changing the structural integrity of the pavers. Some sealants are formulated for a natural matte finish, while others enhance the pavers’ color with a subtle sheen or “wet look” effect.
Here’s what a professional sealing treatment from Property Docktors accomplishes:
-
- Waterproofs the surface: Prevents rain, snow, and sprinkler runoff from soaking into the pavers, which reduces the risk of freeze-thaw damage and efflorescence (white staining caused by salt deposits).
- Protects against UV fading: Blocks harmful ultraviolet rays that can cause paver color to fade, especially in sunny, exposed areas like patios, pool decks, and driveways.
- Resists staining: Helps repel oil, grease, food spills, leaf tannins, rust, and other common sources of surface discoloration.
- Prevents weed growth and joint erosion: Sealing locks in the polymeric sand used between joints, preventing weed seeds from taking root and reducing erosion from rainfall or pressure washing.
- Improves ease of cleaning: Dirt and debris are less likely to stick to a sealed surface, making maintenance quicker and more effective.
- Restores aging hardscapes: On older patios or walkways, sealing can revive dull pavers, restore vibrancy, and unify areas that have worn unevenly over time.
In short, paver sealing doesn’t just make your hardscape look better—it extends its lifespan, improves its safety, and reduces future maintenance costs. That’s why it’s one of the most recommended follow-up services we provide after any new paver patio, walkway, or hardscaping installation.
Benefits of sealing your pavers
Whether you’re protecting a front walkway, a backyard paver patio, or a high-traffic commercial entryway, sealing your pavers offers significant long-term advantages. At Property Docktors, we recommend sealing as a smart, cost-effective way to preserve your investment, reduce maintenance, and enhance the overall appearance of your outdoor living space.
1. Protects against stains and spills
Pavers are naturally porous, meaning they absorb liquids that can leave behind tough, permanent stains. Common culprits include:
-
-
- Oil or transmission fluid from parked vehicles
- Grease and food spills from grills or patio dining
- Rust stains from metal furniture or garden tools
- Fertilizer and leaf tannins from overhanging trees
-
A professional-grade sealant repels these liquids, preventing them from soaking in. This gives you more time to wipe up spills and helps your hardscaping look clean and well-kept.
2. Enhances color and visual appeal
Over time, pavers can lose their vibrancy due to sun exposure, weathering, and wear. Sealing refreshes the natural color of the material and adds a clean, unified finish. Depending on the type of sealant you choose, it can create a natural matte look or a deeper “wet look” that emphasizes:
-
-
- Color variation in concrete or clay pavers
- Joint patterns and edging details
- The architectural design of your outdoor living space
-
This is especially beneficial for older patios and walkways that are starting to look faded or patchy. Sealing is like a facelift for your hardscape.
3. Prevents weed growth and ant intrusion
Without sealing, the joints between your pavers can become a breeding ground for weeds, moss, and insects. As soon as the polymeric sand between joints starts to erode, those tiny gaps give invasive species and pests a place to settle.
Sealing helps:
-
-
- Lock in joint sand, preventing erosion and washout
- Create a barrier that makes it harder for weed seeds to sprout
- Deter ants and other insects from tunneling into the gaps
-
At Property Docktors, we always recommend resealing after a new paver installation or after reapplying polymeric sand during a patio refresh or repair.
4. Guards against freeze-thaw damage
In East Tennessee, temperature swings from warm days to freezing nights are common—especially in the spring and fall. When water enters unsealed pavers and then freezes, it expands. This expansion can:
-
-
- Crack or chip paver surfaces
- Cause uneven settling or shifting
- Lead to gaps, wobbles, and potential trip hazards
-
A proper sealant significantly reduces moisture penetration, helping your patio, walkway, or driveway resist seasonal damage and maintain a level, stable surface year-round.
5. Reduces maintenance and cleaning
Sealed pavers are easier to maintain in every season. Because the surface repels dirt, grime, and organic debris, cleanup becomes much faster and less labor-intensive.
Here’s how sealing reduces maintenance headaches:
-
-
- Power washing is more effective and less frequent
- Leaf stains and mildew are less likely to set in
- Rinsing dirt and spills takes just minutes
- Your hardscape holds up longer between major cleanups
-
That means less time spent scrubbing and more time enjoying your outdoor space.
When should you seal a paver patio or walkway?
We recommend sealing new paver installations about 60–90 days after completion to allow for settling and surface drying. For older patios or walkways, it’s best to clean and re-seal every 2–3 years depending on sun exposure, traffic, and the type of sealant used.
Property Docktors offers both new hardscape installations and maintenance services, including pressure washing and re-sealing of existing paver surfaces.
What happens if you skip sealing?
We understand that some property owners—both residential and commercial—may view paver sealing as an optional upgrade. While it’s tempting to save money by skipping this step, doing so can lead to significantly higher maintenance costs and visible wear in just a few short seasons.
Here’s what you risk by leaving your paver patio, walkway, or driveway unsealed:
Faded, dull-looking pavers
Without sealing, your pavers are left fully exposed to sun, rain, and environmental wear. In East Tennessee, harsh UV rays can bleach the surface, especially in areas with full sun exposure. Over time, the rich color and contrast that made your paver installation look great in the beginning will begin to fade unevenly—diminishing the overall curb appeal of your home or business.
Weed growth and surface disruption
Unsealed paver joints are vulnerable to wind-blown seeds, moss growth, and ant activity. As weeds push through and pests tunnel into the joints, your hardscape starts to lose its uniform appearance and can become uneven or unstable. This not only looks bad but creates trip hazards and future repair needs. Sealing locks in the polymeric sand that fills those joints and helps maintain the structural integrity of your surface.
Staining from common outdoor contaminants
Pavers that haven’t been sealed are more likely to soak up staining substances such as:
-
- Oil or grease from outdoor cooking or parked vehicles
- Leaf tannins, dirt, and organic matter
- Rust from patio furniture or tools
- Food and beverage spills from entertaining
Once absorbed, many of these stains are nearly impossible to remove without harsh chemicals or expensive restoration.
More frequent cleaning and maintenance
Unsealed surfaces tend to collect debris more quickly, and because there’s no barrier to repel moisture, they often require power washing or scrubbing multiple times per year. That means more time, more effort, and more money spent on keeping your hardscape looking presentable.
Increased risk of cracking and shifting
Perhaps the most serious long-term risk of skipping sealing is water infiltration. Moisture can work its way into the surface of your pavers and the joints between them. When temperatures drop, this water freezes and expands—causing cracks, heaving, or paver movement. Over time, this leads to an uneven surface and may require partial or complete hardscape repair or replacement.
By sealing your pavers early—and maintaining them every few years—you protect your investment and avoid the hidden costs of neglect. At Property Docktors, we don’t just build outdoor spaces—we help maintain and extend their beauty and durability.
