When to Replace Granite Countertops

Granite counters are often sold as indestructible. They aren't, but in most cases we see across the GTA they're repairable and worth restoring. After fifty years of stone refinishing, we can tell you that restoring is almost always cheaper than ripping out, and the stone often ends up looking better than when it was installed. See restoration vs. replacement for the basics.

What granite can survive

Granite is hard, dense, and heat-resistant. With reasonable care:

• Counters commonly last decades before anything structural fails
• Dullness, stains, and small chips sit in the surface, and the slab underneath is fine
• Professional polishing and honing removes many stains and scratches that owners assume are permanent

Granite won't forgive years of neglect, acidic cleaners on worn sealer, or cracks that let water into the cabinets. More on our granite page.

Everyday care

Daily cleaning

Use warm water and mild soap, or a pH-neutral stone cleaner. Avoid vinegar, harsh chemicals, and scouring pads.

Resealing

Sealer slows absorption, but it doesn't make stone waterproof forever. Check it with the water-bead test: drip some water on the counter, and if the stone darkens within five to ten minutes, reseal.

• Spot reseal busy areas near the sink and stove as needed
• Reseal the whole counter when several areas fail the test
• Book professional sealing every one to two years, often sooner for light colours

If you seal it yourself, use a sealer that soaks into the stone on clean, dry granite. Surface coatings are rarely right for a kitchen counter.

When marks appear

• Dark shadow in the stone: see stain removal or book professional poultice work
• Dull patch that won't clean off: possibly etching on a calcite-rich "granite"; see stain vs. etch
• Chip on the edge: epoxy chip repair

Restore or replace: what each involves

Cost depends on counter size, edges, seams, and how deep the damage goes, so we don't publish a price list.

Cost factor	Restoration	Full replacement
The work	Diamond grinding, polishing, poultice, and epoxy on the existing slab	Removal, disposal, new slab, templating, fabrication
Materials	Minimal: epoxy, sealer, abrasives	A full slab, plus backsplash stone if it has to match
Plumbing	Usually stays connected	Sink, cooktop, and dishwasher often disconnected and reconnected
Cabinets	Low risk, since the stone stays put	Removing counters can nick cabinets or tile
Timeline	Often 1–2 days for a typical kitchen, plus sealer cure time before heavy cooking	Often 2–4 weeks in busy seasons
Condos and rentals	Surface work is easier to approve	Board approvals, noise, dust, and longer downtime

Rule of thumb from 25,000+ GTA projects: If the slab is structurally sound and you still like the colour, restoring it costs a fraction of replacing it.

Our advice: Get a restoration quote before you sign a replacement contract. Many counters we refinish were headed for the dumpster on looks alone.

What restoration does

Problem	How we fix it
Chips and pits	Colour-matched epoxy, ground flush and polished to blend
Dull, uneven shine	Diamond grinding and polishing
Stains	Poultice to draw the stain out, then sealing

Polishing granite without the right equipment is very hard, and DIY kits often leave swirl marks or dull halos. Deep scratches, cracks, and dullness across the whole counter need a stone restoration company. See dull stone polishing and chip repair.

When replacement makes sense

• It has failed structurally: cracks right through, loose sections, or a base rotted by years of leaks
• You're changing the layout: moving plumbing, adding an island, or changing slab thickness anyway
• The slabs don't match: an earlier partial replacement left colour jumps that can't be blended
• You dislike the stone: no amount of polishing fixes a colour you hate
• Restoring would cost close to new stone: rare on a full kitchen, more common on a small damaged piece

Wear from missed maintenance alone rarely justifies replacement. That's what refinishing fixes.

Two examples

Restore: A 15-year-old kitchen has oil shadows near the stove, a chipped corner by the dishwasher, and dull areas by the sink, but the colour still suits the cabinets. Stain removal, chip repair, polishing, and sealing fix it with the counter in place and the plumbing connected.

Replace: Same kitchen, but the owners are moving the sink and adding a waterfall island, and the base under an old crack has swollen from years of water. The layout drives the project.

Condos, rentals, and home sales

Boards and landlords often prefer restoration because it means:

• Less noise and dust than a tear-out
• No long plumbing shut-off
• A lower upfront cost
• Results that last with regular maintenance

If you're selling or hosting soon, restoration is often the faster way to counters that look good in photos.

Questions to ask any contractor

• Is the slab structurally sound? Cracks right through and moisture underneath change the answer.
• What finish will I get? A restoration quote should say honed, satin, or polished.
• Is sealing included? It's a must after refinishing.
• Can I see similar work? Colour and movement vary, so look at the portfolio.

We don't sell slabs, so we can answer the restore-or-replace question honestly. If replacement is right, we'll say so.
