Delivery Day Inspection Checklist for New Stone Countertops
The crew carries the last piece through the door, the cabinets finally have something on top of them, and the whole kitchen looks done. That moment is also the best chance a homeowner has to catch a problem, because everything the shop did to the stone is visible and nothing has been glued down for good yet. A good inspection takes about half an hour with a flashlight, a straight edge and a little patience.
What should be checked before the pieces are set?
Before any piece goes onto the cabinets, it is worth looking at it standing on edge or lying on the installer's A-frame cart. Stone in this state shows its faults honestly. Hold a flashlight at a low angle across the surface and look for chips, pits and hairline marks. Granite and quartzite often have natural fissures that look like fine lines, and those are part of the stone. A fresh crack has sharp, white edges, and a natural fissure has a dull, weathered look inside it.
Compare each piece to the slab chosen at the yard. In a city where kitchens run from the old bungalows of Hyde Park to the newer builds around Mueller, the slab photos taken at the yard are the best reference for color and veining. If the pattern looks different from the photos, say so right then, while the piece is still off the cabinets.
Which measurements matter on delivery day?
The digital template was taken from the cabinets weeks earlier, so the pieces should fit with very little adjustment. A few quick measurements confirm it.
- Overhang at the island and at any bar: it should match what was agreed, and it should be the same at both ends of the run.
- Gap at the wall: a small, even gap is normal and gets covered by caulk or a backsplash. A gap that opens wider toward one end means the wall bows.
- Reveal at the sink: the strip of sink rim showing past the stone should be even all the way around.
- Clearance at the range and dishwasher: the stone should not rub against the appliance or block the door.
An installer carries a long level and a tape, and a homeowner can ask to see both used. A fair installer will not mind. The level is the more useful of the two, because a top that is set a little high at one corner will show up as water pooling toward the low side.
How does a good seam look and feel?
Seams are the most scrutinized part of any stone counter, and they are also the part most affected by the day itself. Two pieces are pulled together with clamps or suction cups, and a color-matched adhesive fills the narrow gap between them. The result should be a thin line, level on both sides, and close to the color of the stone around it.
Run a fingernail across the seam, crossways. A tight, level seam passes under the nail with almost no catch. A lip, even a small one, usually means one piece was set higher than the other, and it is far easier to correct on the day, while the adhesive is still soft, than after the crew has gone. Look at the seam again from the side with a window behind it. Raking light shows any gap or dip that overhead light hides.
Seams should also sit in sensible places. Stone is weakest around a cutout, so a seam should land a good distance from a sink or a cooktop opening. On an L-shaped kitchen the seam usually sits at the inside corner or near it. If a seam sits somewhere unexpected, ask why. Sometimes the slab simply ran out, and sometimes the layout could have been better.
What does the edge work tell you?
A finished edge reveals how much attention the shop paid in the polishing stage. Run a hand along every exposed edge and along the underside of each overhang, where a rough spot can hide. The profile should be consistent from one end to the other. An eased edge should have the same small round all the way along, and a bullnose should be a smooth half circle with no flat spots.
A laminated edge, built from a second strip glued under the top, should show a joint line that is nearly invisible when viewed from the front. A mitered edge or a waterfall panel should have corners that meet cleanly, with the veining continuing around the bend. A small gap at a mitered corner is a defect, and it will collect grime for years if it is left.
A quick reference for common findings
| What is seen | Usually means | Worth raising? |
|---|---|---|
| Fine dull line in granite or quartzite | Natural fissure in the stone | Only if it feels like a step or a crack |
| Sharp white chip on an edge | Damage during cutting or carrying | Yes, before the crew leaves |
| Lip at a seam | One piece set higher than the other | Yes, it can be adjusted on the day |
| Crack running from a sink corner | Stress at a sharp or poorly radiused cutout | Yes, right away |
| Wider gap at one end of the wall | Bowed wall | Usually normal, covered by backsplash or caulk |
| Pattern that differs from the slab photos | Different part of the slab or different bundle | Yes, while the piece is off the cabinets |
What about the sink cutout and faucet holes?
Cutouts are cut by a CNC router or a waterjet, and the corners should be rounded rather than square. Square inside corners concentrate stress, and a heavy cast iron sink or a thermal shock from a hot pan can open a crack from the corner. Look closely at each inside corner of the sink opening and of any cooktop opening. The edge of the cutout should be smooth, with no chips and no saw marks.
Count the faucet holes against the faucet's spec sheet, and confirm that the position lines up with the sink bowl. A soap dispenser or a side sprayer needs its own hole, and adding one later means drilling through a polished top with the sink in place, which is a job nobody enjoys.
Does the surface itself need attention?
Natural stone such as marble, soapstone and many granites is sealed after fabrication, or sealed once it is installed. Ask whether a sealer has been applied and what it was. A drop of water on the surface should bead up for a few minutes if the seal is working. Quartz and porcelain do not need sealing, and a solid surface top is nonporous too.
Look at the surface across the whole top, with the flashlight again, for swirl marks left by polishing, or for a dull patch where a repair has been made. A repair on a chip or a pit is common and acceptable when it is well done, and it should be nearly invisible. A patch that stands out in raking light deserves a conversation.
What can be done about a problem found on the day?
Most issues have a straightforward answer. A lip at a seam can be adjusted while the adhesive is soft. A small chip can be filled and polished by the installer or returned to the shop for repair. A cracked piece usually goes back, since a crack in a piece of stone cannot be trusted to stay put, and the shop recuts the piece from the slab, or from a matching one if the first slab has been used up.
Take photos of anything questionable before the crew leaves, with a coin or a tape in the shot for scale. A dated photo of the problem and a note about what was said to the installer go a long way toward getting it handled quickly. The weather also plays a part in Austin, since a hot, humid day can speed up the cure of an adhesive, and a cold morning can slow it down. The Balcones Fault and the Texas Hill Country region give the area its mix of limestone and clay, and the same houses that sit on that mix can show small shifts in level that a template picked up weeks ago.
What should be left alone for the first day?
Seam adhesive needs time to cure, so heavy appliances, a loaded stand mixer and a sharp knock on the seam can wait a day. The installer will say how long. Cleaning is simple: warm water and a mild soap on a soft cloth. Skip harsh cleaners on any natural stone, and keep acids such as lemon juice and vinegar off marble.
A careful look on delivery day catches nearly everything a homeowner can catch, and the rest shows up in the first few weeks of normal use.
