Durability
Both quartz and granite are extremely durable surfaces that will hold up to decades of daily kitchen use. Granite is a natural igneous rock, formed under extreme heat and pressure, making it incredibly hard and nearly indestructible. Quartz countertops are engineered by combining about 93% ground natural quartz with 7% polymer resins, creating a surface that is slightly more flexible and less prone to chipping than granite.
In practical terms, both materials resist scratches from normal kitchen use (though you should always use cutting boards). Granite has a slight edge in heat resistance — you can set a hot pan directly on granite without damage, while quartz can be damaged by extreme heat. For the typical home kitchen, both are more than durable enough.
Maintenance
This is where quartz has a clear advantage, and it's a particularly important factor for Seattle homeowners. Quartz is non-porous, meaning it never needs sealing, won't absorb liquids or stains, and naturally resists mold and bacteria growth. Day-to-day cleaning requires nothing more than soap and water or a gentle household cleaner.
Granite is a porous natural stone that requires annual sealing to maintain its stain resistance. If the sealant breaks down (which happens faster in high-use areas), spills like red wine, coffee, and citrus juice can penetrate and stain the surface. In Seattle's humid climate, unsealed granite can also absorb ambient moisture, potentially leading to darkened spots or mineral deposits over time.
Appearance
Appearance is subjective, and both materials are beautiful. Granite offers truly unique, one-of-a-kind patterns — no two slabs are identical. The natural variation includes veining, speckling, crystals, and depth that's impossible to replicate artificially. If you love the idea of having a countertop that's genuinely unique, granite delivers.
Quartz offers consistency, which is its own kind of appeal. You can choose a pattern you love and know that every section of your countertop will look the same. Modern quartz designs have become remarkably sophisticated, with marble-look patterns (like Calacatta and Carrara styles) that are nearly indistinguishable from real marble. This consistency also makes seams less visible, since the pattern is uniform across slabs.
Cost
The price ranges overlap considerably. Entry-level granite ($40-$60/sq ft) is less expensive than entry-level quartz ($50-$70/sq ft). But mid-range and premium options are closely comparable. For a typical 40 square foot Seattle kitchen, here's the cost comparison:
$2,000 - $4,800
Quartz (40 sq ft installed)
$1,600 - $4,000
Granite (40 sq ft installed)
When you factor in the ongoing cost of annual granite sealing ($100-$200 per year over 15-20 years), the total cost of ownership for quartz is often equal to or less than granite. See our complete countertop installation cost guide for detailed pricing on all materials.
Resale Value
Both quartz and granite are considered premium countertop materials that add value to your home. See our kitchen remodel ROI analysis for data on which upgrades deliver the best return. In the Seattle real estate market, quartz has overtaken granite as the most sought-after countertop material among buyers. Real estate agents report that quartz countertops are a strong selling point that signals a modern, well-maintained kitchen. That said, high-quality granite also impresses buyers — particularly unique or exotic slabs that serve as a design focal point.
