1. Why should I seal my pavers?

Professional paver sealing helps protect your hardscape from staining, fading, moisture intrusion and everyday wear. In the Charleston Lowcountry, pavers are constantly exposed to intense sun, heavy rain, humidity and organic growth. A properly selected sealer can make the surface easier to maintain while helping preserve its appearance.

2. How long does paver sealer last?

There isn't one lifespan that applies to every project. How long a sealer performs depends on the type of sealer, paver material, traffic, drainage, sun exposure and maintenance. During an estimate, PaveClean can evaluate the existing surface and recommend the appropriate sealer and maintenance schedule for the property.

3. Will sealing pavers make them slippery?

It depends on the surface and the sealer. That's especially important around pools, steps and frequently wet areas. PaveClean selects professional-grade products based on the surface, location and desired finish, with traction and slip resistance considered when appropriate.

4. Will sealing change the appearance of my pavers?

It can — and that's why choosing the right sealer matters. Depending on the paver or natural stone and the product selected, sealing can maintain a natural appearance or enhance the color of the surface. We'll discuss the desired appearance before selecting a sealer rather than using the same product on every project.

5. Does sealing help with weeds, moss and joint sand?

Proper cleaning, re-sanding and sealing can help stabilize paver joints and reduce joint-sand erosion. It can also make the joints less hospitable to weeds and organic growth. However, sealing isn't a guarantee that weeds or moss will never return. Proper drainage and routine maintenance still matter.

6. Can I seal pavers myself?

Yes, but the preparation is just as important as applying the sealer. Pavers need to be properly cleaned, stains and organic growth addressed, joints prepared and the surface sufficiently dry before the correct product is applied. Improper preparation or application can cause uneven appearance, whitening, trapped moisture and other problems that may be difficult to correct.

7. Can new pavers be sealed?

Yes. New pavers can often be sealed, but the correct timing depends on the paver manufacturer, installation, surface condition and sealer being used. PaveClean uses breathable professional-grade sealing systems when appropriate and evaluates new installations before sealing. Protecting a new hardscape early can help prevent staining and simplify future maintenance.

8. Is paver sealing worth it in Charleston, SC?

For many Charleston-area properties, yes. Our combination of sun, humidity, rainfall, vegetation and coastal conditions can be tough on outdoor hardscapes. Professional cleaning, joint restoration and sealing can protect the appearance of pavers and make routine maintenance easier.

9. Do you have to pressure wash pavers before sealing?

Pavers need to be thoroughly cleaned and properly prepared before sealing, but simply pressure washing them is not enough. We use professional cleaning methods to remove dirt, organic growth, stains, old joint material, and other buildup as needed. Proper surface preparation is one of the most important steps in achieving a clean, even, long-lasting finish.

10. Do you replace the sand between pavers?

Yes. When needed, we remove deteriorated or contaminated joint material and install new joint sand as part of the restoration process. Proper joint sand helps stabilize the pavers, supports the joints, improves the finished appearance, and helps reduce erosion. The type of sand used depends on the paver system and condition of the surface.

11. Can you remove efflorescence from pavers?

Yes. Efflorescence is the white or cloudy mineral residue that can appear on brick and concrete pavers as moisture carries salts to the surface. PaveClean can professionally treat efflorescence as part of the restoration process when appropriate. Because every surface is different, we evaluate the condition of the pavers before determining the proper cleaning and treatment method.

12. Do you clean and seal travertine and natural stone?

Yes. PaveClean provides professional cleaning and sealing for travertine and other natural stone surfaces, including patios and pool decks. Natural stone requires different cleaning methods and sealing products than concrete or brick pavers, so we select the process and sealer based on the specific material, condition, location, and desired appearance.
