Countertop Resealing Service
Keep Your Stone Protected — Year After Year
Natural stone countertops are a significant investment. Regular professional resealing is the single most important thing you can do to protect that investment — preventing stains, preserving appearance, and extending the life of your granite, marble, or quartzite surfaces.
Why Sealing Matters
What Is Stone Sealing — and Why Do You Need It?
Natural stones like granite, marble, and quartzite are porous — they contain microscopic channels and pores that can absorb liquids if left unprotected. When cooking oil, wine, coffee, or acidic substances penetrate those pores, they create stains that are difficult or impossible to fully remove.
A stone sealer is a penetrating liquid that fills those microscopic pores, creating a barrier that causes liquids to bead on the surface rather than soak in. Think of it like the difference between a waterproofed jacket and a regular one in the rain — the stone is the same, but the protection makes all the difference.
Over time — typically 1–2 years — that protective barrier degrades from cleaning, heat, and daily use. Professional resealing restores the barrier before problems start. It is significantly easier and cheaper than repairing a stained or damaged countertop after the seal has failed.

Know Your Material
Which Countertops Need Sealing?
Not all countertop materials require sealing. Here's the definitive guide to what needs sealing, how often, and why.
Most granites need annual sealing. Darker granites may go longer; lighter, more porous slabs may need sealing every 6–12 months.
Marble is the most porous of the common countertop stones and requires the most frequent sealing. Kitchen marble may need sealing every 6 months.
Similar to granite in sealing requirements. Quartzite density varies by slab — your fabricator can advise on how porous your specific stone is.
Engineered quartz is non-porous by design. Sealing quartz does nothing — the product has no pores for the sealer to penetrate. Save your money.
Soapstone is naturally non-porous and does not require sealing. Mineral oil and beeswax are used to enhance and even out its natural patina, but neither is a sealant.
Know the Warning Signs
4 Signs Your Countertops Need Resealing
Your stone will tell you when it's time. Here's what to look and test for.
The Water Bead Test Fails
This is the definitive test. Drop a small amount of water onto your countertop. If it beads up and sits on the surface, your seal is intact. If it soaks in and darkens the stone within 5–10 minutes, it's time to reseal.
Stains Are Appearing
If oils, wine, coffee, or cooking liquids are leaving marks that weren't there before, the sealer has worn down in those areas. A fresh seal will restore the protection — though set-in stains may need professional treatment first.
The Surface Looks Dull or Flat
A worn sealer can make polished granite or marble look less vibrant and reflective than it should. While resealing isn't a polish, fresh sealer applied to a properly cleaned and dried surface often restores the stone's natural depth and luster.
It's Been More Than Two Years
If you can't remember the last time your countertops were sealed — or if they've never been sealed — they're overdue. Annual or biennial sealing is the simplest way to maintain your stone's protection year after year.
Try the Water Bead Test Right Now
Splash a few tablespoons of water onto your granite or marble countertop and watch what happens for 5 minutes.
The water forms droplets and doesn't absorb. Your seal is still working. Retest in 6–12 months.
The water darkens the stone and absorbs. Your seal has worn down. Schedule a resealing appointment.
Professional vs. DIY
Why Professional Resealing Outperforms DIY
Consumer stone sealers from home improvement stores will work — but only if the surface is properly prepared first. Sealer applied over residue, grease, or mineral deposits won't penetrate or bond correctly. This is the most common DIY resealing mistake.
Our professional resealing service starts with a thorough cleaning and degreasing of every surface — removing cooking oils, soap residue, hard water deposits, and any previous sealer breakdown — before applying a commercial-grade penetrating sealer that outlasts most consumer products.
- Full surface cleaning & degreasing
- Commercial-grade penetrating sealer
- Even application by experienced hands
- Longer-lasting protection
- Stain assessment included
- Same-day completion
- Often skips proper surface prep
- Consumer-grade sealer, shorter life
- Uneven application common
- May seal in residue or stains
- Time-consuming to do correctly
- Results depend on skill level
What to Expect
Our Resealing Process
We assess the entire countertop — checking for staining, etching, chips, or buildup that should be addressed before sealing. We'll tell you exactly what we find.
We use professional stone cleaners to strip all grease, soap residue, hard water deposits, and old sealer breakdown from the surface. This is the most critical step — and where most DIY jobs fall short.
We apply a commercial-grade penetrating impregnating sealer evenly across all stone surfaces, working it into the pores for maximum penetration and coverage.
We allow the sealer to penetrate for the appropriate dwell time, then thoroughly buff away all excess product — leaving a clean, protected surface with no haze or residue.
We perform the water bead test on-site to confirm the seal is working properly before we leave. You'll see the results yourself.
Common Questions
Resealing FAQ
Can I reseal my countertops myself?
Yes, consumer-grade stone sealers are available at home improvement stores and will provide basic protection. However, professional resealing includes a thorough cleaning and degreasing of the stone first, which is critical — sealer applied over oil residue or mineral buildup won't bond properly and will underperform. Our professional service also uses commercial-grade penetrating sealers that last longer than most consumer products.
How long does professional resealing take?
For a typical kitchen, professional resealing takes 1–2 hours. This includes cleaning and degreasing the surface, applying the sealer, allowing it to penetrate, and buffing off excess. Your countertops are ready to use the same day, though we recommend waiting 24 hours before exposing the stone to water and liquids.
Do I need to clear my countertops before you arrive?
Yes — please remove everything from your countertops (appliances, items, decorations) before your appointment so we have full access to the entire surface. The more completely we can clean and seal every square inch, the better and more even the protection.
Will resealing remove stains from my granite?
No — resealing does not remove existing stains. It restores the protective barrier to prevent future staining. If you have existing stains, we will attempt to remove them during the cleaning and prep phase, but deep-set stains may require a separate stone poultice treatment. We'll assess your countertops on arrival and let you know what's achievable.
How often should I have my granite countertops professionally resealed?
Most granite countertops benefit from professional resealing every 1–2 years. The exact timeline depends on how porous your specific granite is, how heavily your kitchen is used, and what cleaning products you use (some cleaners strip sealer faster than others). The water bead test is your best ongoing guide.
Does resealing work on quartz countertops?
No. Quartz is an engineered, non-porous stone — it does not have pores for sealer to penetrate. Applying sealer to quartz will either bead off immediately or leave a hazy residue. Quartz never needs sealing. If you have quartz, simply clean it with mild soap and water.
