Most countertop problems are decided on template day, not installation day. Here is how the process runs, what the square-foot price does and does not cover, and the questions worth asking. Tegula Stone connects you with independent fabricators and installers.

Select a slab, then demolition of the old tops, then templating of the exact cabinet layout, then fabrication in a shop, then installation, then the plumber returns to reconnect. The gap between template and install is typically one to two weeks because cutting and polishing stone is shop work. Plan to be without a kitchen sink for that period. Anyone promising template and install in the same week is either holding remnant stock or compressing a step.
Templating is where the installer measures the cabinets as built, not as drawn, and captures out-of-square walls, overhang, sink position and appliance clearances. Cabinets must be installed, level and secured before templating; a countertop templated over cabinets that later shift will not fit. Sinks, faucets and cooktops should be physically on site that day so cutouts match the actual fixture rather than a specification sheet. This is the appointment to be present for.
Any run longer than a slab needs a seam, and in most kitchens at least one is unavoidable. Where it lands is a choice worth making deliberately: seams are commonly placed at a sink, at a cooktop, or at an inside corner, and they should not be placed across an unsupported span. Pattern matching across a seam is possible in some materials and impossible in others. Ask to see a seam diagram before fabrication, not after installation.
Quoted square-foot prices usually include the slab, fabrication of a standard edge, and installation. Frequently excluded: demolition and disposal of the old tops, sink and cooktop cutouts, premium edge profiles, backsplash, plumbing disconnect and reconnect, and any cabinet modification needed to carry the weight. Ask for a written line-item quote based on the actual templated square footage. Comparing two headline per-square-foot numbers with different inclusions is not a comparison at all.
Engineered quartz is non-porous, needs no sealing and resists staining, but can scorch under a hot pan and can discolour in strong sunlight. Granite is heat tolerant and durable, varies slab to slab, and generally wants periodic sealing. Marble is the softest of the four: it etches with acid and patinas with use, which some owners want and others regret. Porcelain slab is very hard and heat resistant, comes in large thin formats, and is more demanding to fabricate.
Cutting engineered stone generates respirable crystalline silica, and California has adopted emergency standards specifically covering this work after serious lung disease was documented among fabrication workers. A shop working responsibly uses wet cutting, dust extraction and respiratory protection. Asking a fabricator how their shop controls silica dust is a fair question, it tells you something real about how the business is run, and it costs you nothing to ask.
Lippage, where two pieces meet at slightly different heights, usually traces to cabinets that were not level before templating. A seam wider or darker than expected is often a colour-matched epoxy choice rather than a defect. Overhangs beyond roughly ten to twelve inches need support brackets and crack without them. Undermount sinks pulling away means the clip and adhesive method was inadequate. Chipping at the sink cutout appears during shipping and should be inspected before the crew leaves.
