Every countertop project starts the same way: a counter that is clean but somehow still reads as dirty, a phone full of photos, and a late-night search. Here is the FAQ homeowners actually run — from first search to first scratch — with honest answers, real numbers, and the trade-offs showrooms skip.

The money questions

What does this cost? Here are our installed ranges as of mid-2026 — slab, fabrication, and installation together: engineered quartz $120–150 per square foot, granite $140–170, quartzite $150–190, marble $170–200. As whole projects, a small kitchen (45–60 sq ft of counter) runs about $5,400–$9,000 in quartz; a medium kitchen (60–75 sq ft) tops out around $15,000 in marble. Laminate costs a fraction of any of these; more on it below.

Why do quotes vary so much for the same stone? Fabrication, not slab: edge upgrades, cutouts, tear-out, seams, backsplash, and whether template, delivery, and install are bundled. Chicago-market benchmarks as of mid-2026: $5–$40 per linear foot for edge upgrades, $150–$400 per sink cutout, $200–$500 for tear-out. Get two itemized quotes on identical specs — we would like to be one of them. A lump-sum quote is a red flag, not a bargain.

Will it pay back at resale? The closest industry proxy — the midrange minor kitchen refresh in the 2025 Cost vs. Value report (Zonda) — recouped roughly its full cost nationally, while major remodels return only 35–50%. Selling soon? Neutral mid-price quartz or granite beats exotic stone: you are buying listing photos, not a decade of living.

The material questions

Quartz vs. granite? Neither wins; they fail differently. Quartz never needs sealing and shrugs off stains, but its resin scorches near 300°F and every manufacturer excludes heat damage from warranty. Granite takes hot pans and every slab is unique, but some stones want occasional sealing. Choose on habits, not rankings.

Does granite really need sealing every year? Mostly myth. The Natural Stone Institute says most granite does not strictly need sealing, and modern sealers last 10–15 years. Use the water test: drops left 15 minutes should bead, not darken the stone. The chore, when needed, is a bottle of sealer and half an hour.

Is marble crazy in a kitchen? It will etch — lemon, wine, and tomato dull the polish and no sealer prevents it. But a documented year-of-ownership account on the Natural Stone Institute's consumer site logged plenty of etching and zero stains, hidden well by a honed finish. The honest question we ask in every marble consult: patina or damage?

Quartz vs. quartzite? Opposites, despite the names: quartz is engineered stone-and-resin; quartzite is natural rock — harder than granite, heat-proof, marble-looking, but it needs sealing and sits above granite in our installed ranges at $150–190 per square foot. Some "quartzite" is mislabeled softer stone; ask for a scratch test — we do them happily.

Is laminate still legitimate? Yes, at a fifth the price of stone — its enemies are water in the seams (the particleboard core swells permanently) and hot pans (no repair path). We do not install laminate, so read this as neutral: right for budgets, rentals, and flips; wrong for heavy sink use or undermount sinks.

The process nobody explains

Buy your sink first. The sink must physically be on site at template day so the cutout can be traced. The no-sink ambush is the most common schedule-killer we see, costing 3–7 days.

Template day: 30–90 minutes; cabinets must be installed, level, and anchored. Template to install: typically 5–15 business days (peak season up to 20) — and your kitchen keeps working through fabrication; you only lose the sink for a day or two. Install day: 2–6 hours. Installers usually do not reconnect plumbing — ours included — so book a plumber for the day after, once adhesives cure.

Seams are real. Expect roughly 1/16-inch, color-matched, placed over supports — visible up close and feelable by fingernail, on purpose. Ask how many, where, and from how many slabs — we show the seam plan before cutting. Inspect while the installers are still in the house. Anyone promising invisible seams is overpromising, and a seam through the sink perimeter is the one to veto — water always finds it.

Living with it

Quartz care is dish soap and water — but skip abrasives, bleach, and oven cleaner (they attack the resin), and keep trivets in reach: the brown ring near the stove in so many service calls is a permanent resin burn, excluded from warranty.

Watch the sink perimeter. Dark, soft caulk means water is through. In homeowner timelines we studied, recaulking bought about a year once swelling started, and untreated sink leaks rotted the cabinet below within 2–3 years. Recaulk at first darkening — a $15 job — and treat soft substrate as a replacement conversation.

Repair beats replacement more often than people think. Chips fill with color-matched resin ($150–$400, a Chicago-market benchmark), stone re-polishes in place, butcher block sands back to new. The unfixables: quartz scorch, laminate water damage, and cracks that cross a sink corner or seam.

The bottom line

Pick the weakness your household will not trigger, buy the sink before the template, demand an itemized quote, and go meet your slab in person — a 3-inch chip is a hint, not a decision. Company for the slab visit is literally our job.
