Quartz vs granite comes down to four things in a Houston kitchen: quartz costs about $10 to $30 more per square foot on mid-range slabs and never needs sealing, while granite takes a hot pan and works in a covered outdoor kitchen (SlabWise 2026, Fixr 2025, Cambria). Installed, quartz runs $50 to $150 per square foot and granite $40 to $100, so a typical 50 square foot kitchen is roughly $3,500 to $6,000 in quartz and $2,300 to $4,500 in granite.
Kitchen Remodel Masters fabricates and installs both from its own Houston shop, so this guide has no reason to steer you toward one. Below is one comparison table, a short section per row, and a “which one for your kitchen” list. Prices are published market ranges with sources, not a KRM quote.
| Quartz | Granite | |
|---|---|---|
| What it is | Engineered: about 90% ground quartz in resin | Natural igneous stone, quarried and polished |
| Cost installed per sq ft | $50 to $150, most $70 to $100 (SlabWise 2026); $50 to $200 (Fixr 2026); $74 to $99 (Thumbtack 2026) | $40 to $100 (SlabWise 2026); $45 to $75 Houston common slabs (Sugar Land Stone 2025); material $40 to $200 plus ~$30 install (Fixr 2025) |
| Durability | Very hard, resists scratches; resin edges can chip | Very hard, resists scratches; edges can chip |
| Heat | Trivet required; resin scorches (MSI: ~300°F limit) | Takes a hot pan (Fixr 2025); trivet still advised |
| Stains and sealing | Non-porous, never sealed | Slightly porous; seal every 1 to 5 years (SlabWise 2026) |
| Look and pattern | Consistent; marble-look whites, concrete, solids | One-of-a-kind; speckles and movement, each slab differs |
| Outdoor use | Not approved for outdoor use (Cambria); UV yellows resin | Yes, under a cover |
| Resale | No proven premium either way (SlabWise 2026) | No proven premium either way |
| Maintenance | Wipe with warm water and mild soap | Neutral stone cleaner; reseal on schedule |
Granite is usually the lower number, but not by as much as people expect.
SlabWise (July 2026) puts granite at $40 to $100 per square foot installed (entry $40 to $55, mid $55 to $80, premium $80 to $120 and up) and quartz at $50 to $120 (entry $50 to $65, mid $65 to $90, premium $90 to $130 and up). The typical gap on mid-range slabs is $10 to $30 per square foot. Entry-level granite and entry-level quartz can land at nearly the same price, and an exotic granite like Blue Bahia, at $120 to $200 per square foot in material alone (Fixr 2025), costs more than any mainstream quartz.
Houston-specific numbers: Sugar Land Stone (2025) lists common granite at $45 to $75 per square foot installed. SlabWise’s South Central regional range for quartz, which covers Texas, is $60 to $115. Thumbtack (July 2026) reports quartz at $74 to $99.
Long-term, add granite’s sealing. SlabWise (2026) estimates $100 to $400 over 10 years, either as $15 to $40 in DIY sealer per application or $50 to $150 for a professional visit. Quartz has no equivalent cost. Over a decade the two materials end up close.

Both will outlast the cabinets under them. The difference is where each is weak.
Quartz is uniform all the way through. It resists knife scratches, does not stain, and does not etch from lemon or vinegar. Its weak points are heat and UV, both because of the resin.
Granite is as hard or harder and has no resin to scorch or yellow. Its weak points are porosity, which sealing handles, and natural fissures or pits. Edges on both can chip from a hard knock at a sink corner; both are repaired with color-matched epoxy.
This is granite’s clearest win. Fixr (2025) describes granite as heat-resistant and able to take a hot pan without a trivet. The Natural Stone Institute still recommends trivets or mats on any stone, because a sudden temperature change near an edge can stress it.
Quartz needs a trivet, full stop. MSI rates its Q quartz to about 300 degrees Fahrenheit before scorching, and Cambria’s product specification sheet says its product may not withstand direct heat from pots, electric frying pans, griddles, slow cookers or heat lamps. Fixr (2026) adds that many quartz warranties exclude heat marks. If you cook with cast iron and set it down wherever it lands, that matters.
This is quartz’s clearest win. Quartz is non-porous; MSI describes its Q quartz as 99.9 percent solid with no sealing, polishing or reconditioning required. Wine, coffee and oil sit on top and wipe away.
Granite is slightly porous. A penetrating sealer closes the pores so liquids bead instead of soaking in. SlabWise (2026) puts resealing at every 1 to 5 years: light, porous granites such as whites and creams every 1 to 2 years, dense dark granites every 4 to 5 years or longer. The test is simple. Pour a few tablespoons of water on the counter; if the stone darkens within 5 minutes, reseal. A bottle of impregnating sealer is $15 to $30 and the job takes about 30 minutes plus a 24 to 48 hour cure. Many fabricators seal at installation (Fixr 2025).
The Natural Stone Institute notes that sealing makes granite more stain-resistant, not stain-proof, and that granite, as a siliceous stone, does not etch from common kitchen acids the way marble does.
Quartz is consistent. The showroom sample matches the slab, long runs seam cleanly, and the marble-look whites most Houston clients want, Calacatta and Carrara styles, are a quartz specialty. Concrete grays, warm creams and solids are easy to find.
Granite is one of a kind. You tag the exact slabs at a Houston stone yard. Speckled patterns dominate, from Uba Tuba’s dark green-black to New Venetian Gold’s cream and brown. White granites (Colonial White, Kashmir White) carry more variation than a white quartz. Honed and leathered finishes, $10 to $25 extra per square foot (Fixr 2025), give granite a matte texture that hides water spots.
Granite, by default. Cambria’s product specification sheet states its quartz is not approved for outdoor use, and most quartz brands say the same because UV light yellows the resin. Fixr (2026) notes that many quartz warranties exclude sun fading. Houston sun is direct for most of the year, so even a covered patio with afternoon exposure is a risk for standard quartz.
Granite has no resin, so it does not change color in sun. It handles grill heat and, once sealed, rain and humidity. Quartzite and porcelain are the other two outdoor-rated options. For any outdoor kitchen Kitchen Remodel Masters installs granite, quartzite or porcelain under a cover.
Neither material has a proven resale premium. SlabWise (2026) notes that Remodeling’s Cost vs Value report does not separate countertops from the rest of a kitchen remodel, which recovers roughly 30 to 86 percent of its cost. Buyers respond to a clean, updated, low-maintenance kitchen, and either material delivers that.
Quartz: warm water and a soft cloth daily, mild dish soap for grease. Skip abrasive powders, bleach scrubs and stone sealers, which can dull or haze the resin.
Granite: a neutral stone cleaner daily, reseal on the schedule above. The Natural Stone Institute warns against rust removers and toilet bowl cleaners, which can contain hydrofluoric acid and attack any stone, granite included.
Both: wipe standing water around the sink. Houston tap water leaves a white mineral film on either surface when it dries, most visible on polished dark stone. It is not damage, and a weekly neutral-cleaner wipe keeps it from building up.
Two other slabs come up on KRM consultations.
Quartzite is a natural metamorphic stone, not quartz. It is harder than granite, takes heat, works outdoors under cover, and gives real marble-like veining in white and gray. It is sealed like granite and costs more: $80 to $210 per square foot installed (Fixr 2025), $75 to $130 in Houston (Sugar Land Stone 2025). The flat-panel cabinets with quartzite countertops project shows one in a Houston kitchen.
Porcelain slab is a fired ceramic, thin (usually 12 mm), non-porous, heat-tolerant and the most UV-stable of the group, so it is strong for outdoor kitchens and full-height backsplashes. Patterns are printed, so edges show the core. Fixr (2026) lists $55 to $120 per square foot installed.
The broader guide to all five materials, including marble, is how to choose the right countertop in Houston.
The material pages go deeper on each: quartz countertops in Houston and granite countertops in Houston. Both are part of countertop replacement in Houston.

Granite is usually a little cheaper. SlabWise (July 2026) lists granite at $40 to $100 per square foot installed and quartz at $50 to $120, with a gap of about $10 to $30 on mid-range slabs. Entry-level granite and entry-level quartz can cost nearly the same, and exotic granite can cost more than premium quartz. These are market ranges, not a Kitchen Remodel Masters quote.
Both last decades. Quartz is non-porous and does not stain, but its resin can scorch under a hot pan and yellow in sunlight. Granite is harder against heat and fine outdoors, but it is slightly porous and needs sealing every 1 to 5 years (SlabWise 2026). Durability comes down to which weakness you can live with: heat and sun for quartz, sealing for granite.
Granite handles it; Fixr (2025) says granite can take a hot pan without a trivet. Quartz cannot. MSI rates its quartz to about 300 degrees Fahrenheit before scorching, and Cambria's product specification sheet calls for a solid trivet under pots, griddles and slow cookers. Use a trivet on both to be safe.
Granite does, every 1 to 5 years depending on how porous the stone is (SlabWise 2026). Light granites need it more often than dense dark ones. Quartz never needs sealing because it is non-porous. A bottle of granite sealer costs $15 to $30 and the job takes about 30 minutes.
Granite. Standard quartz is not approved for outdoor use (Cambria product specification sheet) because UV light yellows its resin, and Fixr (2026) notes many quartz warranties exclude sun fading. Granite, quartzite and porcelain all hold up under a covered outdoor kitchen in Houston.
Neither has a proven premium over the other. SlabWise (2026) notes that Remodeling's Cost vs Value data does not separate countertops from the rest of a kitchen remodel. Buyers respond to a clean, updated kitchen in either material. Pick the one that fits how you cook and where the counter sits.
No. Quartzite is a natural metamorphic stone, cut and sealed like granite, and harder than both quartz and granite. Quartz is engineered stone made of ground quartz and resin. Quartzite costs more: Fixr (2025) lists $80 to $210 per square foot installed and Sugar Land Stone (2025) gives a Houston range of $75 to $130.
No. Both show the same white mineral film when tap water dries near the sink. It wipes off with a neutral cleaner on either surface. It shows most on polished dark stone, so honed or leathered finishes and lighter colors hide it best on both materials.
