How do quartz and granite countertops compare for New Brunswick kitchens?

Quartz edges out granite as the better overall choice for most New Brunswick kitchens due to its zero-maintenance surface and superior performance in NB's humidity swings, though granite remains an excellent option for homeowners who prefer natural stone and do not mind annual sealing. Both materials are durable, beautiful, and widely available through fabricators in Moncton, Fredericton, and Saint John.

Quartz is an engineered stone made from approximately 90 to 94 percent ground natural quartz bound with polymer resins. It costs $60 to $120 per square foot installed in New Brunswick. Its defining advantage is that it is completely non-porous, meaning it never needs sealing, does not absorb stains, and resists bacterial growth. In a province where summer humidity can push indoor moisture levels high enough to promote mould on porous surfaces, quartz's sealed composition is a significant practical benefit. It is available in a vast range of colours and patterns, including convincing marble and concrete looks that are difficult to distinguish from natural stone.

Granite is a natural stone quarried from the earth, with each slab being unique. It costs $55 to $110 per square foot installed in New Brunswick. Granite is naturally heat-resistant, which means you can set a hot pan directly on it without damage. This is granite's single biggest functional advantage over quartz, which can be damaged by temperatures above 150 degrees Celsius. However, granite is porous and requires sealing once a year to prevent stain absorption. In NB's humid summers, an unsealed or poorly sealed granite counter can absorb moisture, and dark spots or bacterial growth can develop over time.

Performance in NB's Climate

New Brunswick kitchens experience significant environmental variation throughout the year. Summer humidity levels indoors can reach 60 to 70 percent, while forced-air heating in winter drops humidity to 15 to 25 percent. Quartz is unaffected by these swings because its resin binder makes it dimensionally stable. Granite is also largely stable, but the sealant on granite can break down faster in conditions where humidity fluctuates, requiring more attentive annual resealing to maintain protection.

For kitchens on exterior walls, which see the greatest temperature variation, both materials perform well structurally. Neither will crack or warp from NB's temperature range. The difference remains in the maintenance: quartz needs only soap and water year-round, while granite needs annual sealing to perform at its best.

Practical Comparison

Durability is comparable for daily use. Both resist scratches from normal kitchen activity, though neither should be used as a cutting board surface. Granite is slightly more prone to chipping at edges and around sink cutouts because it is a natural material with internal grain lines that create stress points. Quartz's uniform composition makes it more consistent in edge strength.

Appearance is where personal preference matters most. Granite offers one-of-a-kind natural patterns with depth and movement that engineered stone cannot perfectly replicate. If you value the uniqueness of natural stone and enjoy knowing that no other kitchen has the exact same slab, granite wins this category. Quartz offers more predictable, consistent patterns and a wider colour range, which makes it easier to match to a specific design vision.

Resale value is essentially equal. Both quartz and granite are considered premium countertop materials in the New Brunswick real estate market, and either will be viewed favourably by buyers compared to laminate or solid surface options.

Lead times are similar at 3 to 6 weeks from templating to installation for both materials. Templating must be done after cabinets are fully installed and levelled. Most NB fabricators stock popular quartz colours but order granite slabs to specification, so selecting a granite slab in person at the fabricator's yard is recommended to ensure you are happy with the specific natural pattern.

The bottom line: choose quartz if you want a maintenance-free surface that handles NB's climate without any attention. Choose granite if you love natural stone's unique beauty and are willing to seal it annually. Either is a strong investment in your NB kitchen.
