What moves it
Why two of the same job cost different amounts
These apply at the same time and in both directions. Which of them is true of your kitchen is what the on-site diagnostic settles.
-
How many valves
The labor of reaching the manifold is the same for one or four, so all of them are assessed.
-
Rebuild or replace
Residue can be cleaned. A galled taper cannot, and we say which.
-
Knob, bezel or stem
Sometimes it is not the valve at all, and that is cheap to establish.
-
Where the valve sits
A knob next to the plaque or the grill lives hotter and ages first.
-
Corrosion
A coastal kitchen reaches the stem behind the knob and works inwards.

from $195 Burner knob and valve rebuild
Brass knobs on mechanical valves, used several times a day for decades in a humid kitchen. Stiffness is the early warning; a knob that will not return cleanly to off is the reason this is not a job to postpone.
- A stiff valve is failing, not dry — it is rebuilt or replaced
- Knobs, bezels and stems treated as wear parts
- Every valve on the range checked, not only the one complained about

About La Cornue burner knob and valve rebuild cost
Why we work all of them
Every valve on your range has done the same number of years in the same kitchen air. When one has gone stiff the others are usually a season behind it, and getting to the manifold costs the same whether we assess one valve or six. So the visit works every knob, and the report says which are fine, which are marginal and which need doing — then you decide. It is the difference between one visit and three, and it is the reason this figure is not per valve.

Questions about La Cornue burner knob and valve rebuild cost
It is only slightly stiff. Can it wait?
For a while, if it still shuts off completely and firmly. Not if it needs coaxing to off, and not if it has begun to feel gritty rather than firm — grittiness is metal on metal and it accelerates. The other argument is practical: a stiff valve gets forced, and a forced knob is how stems shear, which leaves a burner stuck on whatever setting it was last left at.
The knob spins without turning anything.
Opposite problem, usually cheaper. A worn knob or a stripped stem, with a valve underneath that may be perfectly sound. Take the knob off and turn the stem gently — if it moves properly, it is a knob, which is an ordinary wear part on a range this age. Tell us which of the two you have, because we bring different things.
