Question 1

How much does cooktop maintenance cost?

Accepted Answer

A cooktop maintenance visit starts from $195, and the $80 diagnostic ($100 commercial) comes off the total once you approve the written estimate. We do not quote exact prices before we see the unit - what moves the number is which checks your cooktop needs and what the technician finds under the surface. An igniter that has already fouled and failed needs a part, and a hairline crack in a glass-ceramic top means a surface replacement, since we replace a cracked surface and cannot repair it. On sealed-burner professional cooktops the burner cups sit in the surface itself, so the technician has less access than on a standard residential unit. You approve the written estimate before any of that work starts, and parts and labor carry a 180-day warranty.

Question 2

How often should I service my cooktop?

Accepted Answer

Once a year is right for most cooktops, with a little extra attention for gas. Clean the surface after each use, and once a month pull the burner caps and grates to soak and scrub the ports - clogged ports are what cause yellow flames and uneven heat. Check that flames burn steady blue. In coastal homes - Sausalito, Tiburon, Pacifica, Montara - salt air corrodes burner grates and igniter electrodes faster, so a light wipe of cooking oil on cast-iron grates after cleaning helps hold off rust. Sealed-burner professional cooktops from Thermador, Wolf, and Viking limit how much you can clean yourself and benefit from yearly professional service. For induction, keep the underside vents clear of dust.

Question 3

What does cooktop maintenance include?

Accepted Answer

A visit runs 45 to 60 minutes and covers six things. We pull the burner caps and deep-clean the ports, because grease and food debris in the ports turn a flame yellow and create hot spots, and left long enough they damage the igniter, a from-$265 replacement. We test the igniter on every burner, then clean and align the electrode, which is usually all a burner that clicks without lighting needs. On gas models we check the supply line and the shut-off valve for micro-leaks with a soapy water test or an electronic detector. We inspect glass-ceramic surfaces for micro-cracks, since a hairline crack is an electrical hazard that ends in a from-$600 surface swap. On induction we test each zone and confirm the underside vents are clear, because these units build heat internally. Then we check the control knobs and switches, where a loose knob points to a worn valve stem. You get a written report of what we found.

Question 4

What are signs my cooktop needs maintenance soon?

Accepted Answer

Watch for: burner flames that burn yellow instead of blue, a burner that clicks but won't light, a zone that takes too long to heat, new scratches on the glass, or control knobs that feel loose. Most of these trace back to clogged burner ports, a dirty or misaligned igniter, or a worn valve stem - all routine maintenance items. A visit clears them cheaply; ignored, a fouled igniter fails at a from-$265 replacement, and a hairline crack in a glass-ceramic top is an electrical hazard that ends in a from-$600 surface swap. Gas is different - if you smell it, switch nothing on, ventilate, leave, and call PG&E at 1-800-743-5000. If the cooktop is already dead, book a repair; we diagnose it the same way and the $80 still applies.

Question 5

Can you replace a cracked glass cooktop?

Accepted Answer

A cracked glass or ceramic surface has to be replaced, not repaired - a crack is both an electrical and a cut hazard. We assess the damage, quote the replacement, and can source and fit new glass for most brands and models, from $600 depending on the unit.

Question 6

Do you service all cooktop types and brands?

Accepted Answer

Yes. We service gas, electric coil, radiant glass, and induction cooktops from all major brands including Bosch, GE, Frigidaire, Samsung, LG, KitchenAid, Thermador, and Wolf. Two configurations benefit from a yearly professional visit. On sealed-burner professional cooktops the burner cups sit in the surface itself, which limits how far you can clean them yourself. Induction asks little day to day, though an annual diagnostic catches control board error codes early and confirms the ventilation underneath is clear. On gas models we also run a supply line and shut-off valve safety check with a soapy water test or an electronic detector. If something has to be replaced, common parts arrive in 2 to 4 business days and specialty components take longer. We quote the lead time before you approve the work. Parts and labor carry a 180-day warranty.

Maintenance task	What you avoid
Burner port cleaning	Clogged ports cause uneven flame, hot spots, and igniter damage ($265+). Regular cleaning restores even heat distribution.
Gas connection safety check	We test the supply line and the shut-off valve for leaks before they turn dangerous. Every gas cooktop needs this check.
Glass surface inspection	Catching micro-cracks early on glass-ceramic cooktops prevents electrical hazards and full-surface replacement (from $600).
