Every countertop service we offer
Our team provides new quartz, granite and solid surface tops, delivering long-lasting countertop fixes for homes and contract fabrication for both residential and commercial projects. We lay out every seam on the slab you pick and send that seam plan for your sign-off before cutting, and each finished job carries a written warranty.
From the water test that shows whether granite is still sealed to tear-out, template and a new top on sound cabinets, our team handles every detail. Serving Rancho Cucamonga plus Claremont, La Verne and Chino, we match the fix to the condition of the top rather than selling a replacement nobody needs.

Repair, refinish, reseal or replace: match the service to the condition
The right countertop service in Rancho Cucamonga is decided by what is actually wrong with the top, so we sort every call by symptom before we talk about price. Most problems fall into one of six conditions, and each one has its own service page.
A chip, a crack or a seam that has opened: repair
A chipped edge, a hairline crack or a seam whose filler has broken down is a repair. We fill with color-matched resin, cure it, and polish it flush. A top that has cracked clean through a span or over a sagging cabinet is a different conversation, because the support underneath has to be fixed first.
A dull ring or a cloudy patch on marble: polishing and etch removal
A dull mark where lemon juice, wine or vinegar sat on marble is an etch, not a stain. Marble is calcite or dolomite, and acids react with its calcium carbonate and eat into the polish. Sealer does not stop that, so an etched top needs polishing back to its original finish, not another coat of sealer.
Water darkens the stone: sealing
If a small pool of water turns granite darker within about 30 minutes, the sealer has worn away and the stone is absorbing liquid. That is the simple water test stone-care makers publish, and it is the one we run at the visit. Quartz never needs this, because engineered quartz is not sealed like natural stone.
The undermount sink has dropped or pulled away: sink reattachment
A gap opening between the sink rim and the stone means the clips or adhesive holding the sink from below have failed. We support the bowl, clean the old bond, and reattach it before the gap lets water rot the cabinet floor.
A worn or dated surface on an older top: refinishing
Refinishing puts a new coating over an old laminate or cultured marble top that is structurally fine but tired to look at. It is the budget path for a rental or a kitchen being sold soon.
Everything else: replacement
Deep stains in porous stone, a top cracked through, tile grout that will not come clean, or simply a kitchen you have outgrown all point to a new top.
Keep the cabinets or replace them too: the test that decides
A new top can go on your existing cabinets when the boxes are square, level and solid, and it should not when they are not. We check every base cabinet with a level at the measure and look underneath the sink for water damage, because stone set on a failing box will crack along the weak point.
- Sound, level cabinets you like: countertop replacement, done without touching doors, floors or paint.
- Cabinets that need a shim or a new rail: replacement, with the cabinet work quoted as its own line.
- Soft, swollen or sagging boxes, or a layout you want to change: new cabinets first, then kitchen countertop installation in the trade sequence, with templating after the cabinets are set.
This is where two of our service pages split. Countertop replacement keeps your cabinets and is mostly a tear-off day. Kitchen countertop installation follows a remodel with new cabinets, where the cabinet installer, our template, the install and the plumber all happen in order.
Residential services by room
Once the condition says new stone, the room decides which service fits.
Kitchen
Kitchen countertop installation for a remodel with new cabinets. Countertop replacement over the cabinets you already have. Kitchen island countertops, where overhang support and slab size decide the job. Waterfall edge countertops, where a mitered fold carries the stone down to the floor. Full-height slab backsplash, where the top continues up the wall in one material.
Bath
Bathroom vanity tops, single or double, often cut from a remnant of a larger slab.
Outside
Outdoor kitchen countertops, where sun and summer heat narrow the material list.
By material
Granite countertop installation, when you want to choose the actual slab. Quartz countertop installation, engineered stone that needs no sealing. Solid surface countertops, with joints sanded flat so seams all but vanish. Concrete countertops, poured or precast.
Services for contractors, builders and property managers
Trade and commercial buyers skip the homeowner decision tree entirely. Nobody running a job needs to be asked whether their top is etched or stained; they need a price from drawings and a date on the schedule.
- Commercial countertop installation: the starting point for general contractors, developers and facility managers bidding from plans.
- Wholesale countertop fabrication: fabricate-only or fabricate-and-install tops for cabinet shops, remodelers and designers who keep their own client.
- Builder countertop packages: tops cut plan by plan across a phase of new homes.
- Multifamily countertops: unit packages by unit type, including occupied turnovers.
- Tenant improvement countertops: office, medical and retail suites, with accessible counter heights and after-hours work.
- Restaurant and bar countertops: food-contact surfaces and bar tops built for a health inspection.
- Hotel and hospitality countertops: vanities and lobby work approved from a mockup room first.
Send the plans, the finish schedule or the unit counts and we come back with a bid.

The size of the damage, the stone and how far it has to be matched move the small jobs. Square footage, slab count, edge, cutouts and tear-out move the large ones. All of these figures are estimates and are subject to change; the final price is the one in your written quote after we see the top in person.

Questions
Questions About Our Services
Should I repair my countertop or replace it?
Repair it when the damage is local, such as a chip, an opened seam or a dropped sink, and the top is otherwise sound. Replace it when it is cracked through, stained deep into porous stone or sitting on failing cabinets. We tell you which at the visit, before any quote.
How do I know if my granite needs sealing?
Pour a small puddle of water on it and wait about 30 minutes. If the stone darkens, it is absorbing water and needs sealing; if the water beads and the color holds, the sealer is still working.
Is a dull spot on marble a stain?
Usually not. A dull, rough patch where something acidic sat is an etch, where the acid has reacted with the calcium carbonate in the stone. It is fixed by polishing, not by sealing or stain removal.
Can you put a new top on my old cabinets?
Yes, when the cabinets are level, square and dry underneath. We check each box at the measure and quote any shimming or support work separately so you can see it.
How much does a countertop repair cost?
Most chip and crack repairs are typically estimated at roughly $150 to $500, depending on the size of the damage and how hard the stone is to color match. Your written quote sets the final price.
Do you work with contractors and cabinet shops?
Yes. Contractors, cabinet shops, builders and property managers start from our commercial and wholesale fabrication pages, where work is priced from drawings, finish schedules and unit counts rather than a homeowner visit.
Can a countertop be refinished instead of replaced?
An older laminate or cultured marble top that is structurally sound can take a new coating. Granite and quartz are not refinished this way; they are repaired, polished or replaced.
Is the work covered by a warranty?
Every finished job includes a written warranty, and we explain what it covers when the work is done.
