Granite countertops are celebrated for their beauty, durability, and timeless appeal. However, maintaining their longevity and appearance requires regular sealing. Failing to seal granite countertops annually can lead to several problems that not only affect the countertop’s aesthetics but also its functionality and hygiene.
In this comprehensive guide, we’ll explore what happens if you skip sealing your granite countertops, why sealing is important, and how to ensure your investment remains in pristine condition. If you’re searching for expert advice or premium granite products from trusted granite countertop stores Westfield, IN, Granite Depot of Indianapolis is your go-to provider.
Why Does Granite Need to Be Sealed?
Granite is a natural stone that is formed under immense pressure and heat. While incredibly durable, it is naturally porous, which means liquids, oils, and other substances can seep into the surface if not properly sealed. The sealing process creates a protective barrier that prevents stains, water damage, and bacterial growth.
Key Benefits of Sealing Granite:
- Stain Resistance: A proper seal prevents liquids like wine, coffee, or oil from penetrating the surface and leaving permanent stains.
- Moisture Protection: Sealing keeps water from seeping into the stone, reducing the risk of damage or discoloration.
- Enhanced Durability: A sealed surface is less prone to chipping, cracking, or other forms of wear and tear.
- Improved Hygiene: Sealing minimizes bacteria and mold growth by keeping the stone’s pores sealed.
Regular sealing is especially important for high-traffic areas like kitchen countertops or bathroom vanities.

What Happens If You Don’t Seal Granite Every Year?
If you neglect sealing your granite countertops, several issues can arise over time. Let’s take a closer look at the potential consequences:
1. Staining
One of the most common problems with unsealed granite is staining. Without a sealant, the porous surface of granite can absorb liquids like oil, wine, coffee, or juice. These substances can leave unsightly stains that are nearly impossible to remove.
Example:
- Spills in the kitchen can quickly soak into the surface, leaving dark patches that ruin the countertop’s natural beauty.
- Bathroom products like makeup, lotions, or shampoos can also stain unsealed granite.
2. Water Damag
Unsealed granite is highly susceptible to water absorption. Over time, water can seep into the stone, causing discoloration, etching, or even cracking. This is particularly problematic in areas with high humidity or frequent exposure to water, such as bathrooms or around sinks.
Effects of Water Damage:
- Dark spots or cloudy marks appear on the surface.
- Freezing and thawing cycles in colder climates can cause cracks.
3. Bacterial Growth
The porous nature of unsealed granite provides an ideal environment for bacteria, mold, and mildew to thrive. This can compromise the hygiene of your kitchen or bathroom, making the countertop unsafe for food preparation or daily use.
Health Risks:
- Bacteria can accumulate in the pores, creating unsanitary conditions.
- Mold and mildew can emit unpleasant odors and potentially cause health issues.
4. Dulling and Loss of Shine
Granite countertops are prized for their glossy, polished appearance. Without regular sealing, the surface can become dull over time due to the buildup of dirt, oils, and grime.
Visual Impact:
- The countertop loses its vibrant color and natural patterns.
- It requires more intensive cleaning to restore its original luster.
5. Increased Maintenance
Unsealed granite countertops are more challenging to clean and maintain. Stains and spills are harder to remove, and the porous surface traps dirt, requiring more frequent and labor-intensive cleaning.
Example:
- Simple spills that would wipe off a sealed countertop may require scrubbing or specialized cleaning products on an unsealed surface.
6. Shortened Lifespan
Granite countertops are a long-term investment, but failing to seal them regularly can reduce their lifespan. Damage from stains, water, and everyday wear accelerates the deterioration of the stone, potentially leading to costly repairs or replacement.
Financial Implications:
- Neglecting maintenance can result in the need for professional restoration services.
- In severe cases, the countertop may need to be replaced entirely.
How Often Should You Seal Granite?
The frequency of sealing depends on several factors, including the type of granite, the quality of the sealant, and how often the countertop is used. While many experts recommend sealing granite annually, some higher-quality sealants can last up to 3–5 years.
Testing Your Countertop: Perform a simple water test to determine if your countertop needs sealing:
- Pour a small amount of water onto the surface.
- Observe how the water behaves:
- If it beads up, the countertop is still sealed.
- If it soaks into the stone and darkens it, it’s time to reseal.
Regularly testing your countertops ensures they remain protected and helps you avoid the issues associated with unsealed granite.

Tips for Proper Granite Maintenance
In addition to sealing, here are some tips to keep your granite countertops in excellent condition:
- Clean Daily: Wipe the surface with a pH-neutral cleaner or warm soapy water to remove dirt and debris.
- Avoid Harsh Chemicals: Avoid using acidic or abrasive cleaners, which can damage the sealant and stone.
- Wipe Spills Immediately: Promptly clean up spills to prevent stains, especially from acidic or oily substances.
- Use Cutting Boards and Trivets: Protect the countertop from scratches and heat by using cutting boards and trivets for food preparation and hot items.
- Reseal as Needed: Test the countertop regularly and reseal it whenever necessary to maintain its durability and appearance.
