4 cylinder or V6?  I went to ARRC to get the book times for the jobs required
as per below:

Timing Belt is 2.2hrs for 4cyl, 3.5hrs for 6cyl, plus $60 for the belt.
Another $40-50 for the water pump (labor inc in timing belt except for about
15 minutes).  The thermostat is $20, 1hr install.

Drive belts are $20 each or so (maybe cheaper).  Labor is combined with
Timing Belt. (You have to remove the drive belts to do the timing belt)

Spark Plugs have to be removed to do the valve adjustment, they are $25-40
depending what kind you get.  Valve adjustment should be 1.3 hours 4cyl, 4.
9hrs 6cyl (according to the book.  This seems very high), some combined labor
with timing belt, means discount at a good mechanic.

There is no such thing as a water filter.  Maybe a cabin air filter, not sure
if the 2000 accord came with that.

Adding up the above at $100/hr, it should come to about $680 for 4cyl, $1110
for 6cyl.  Not included in that price is new fluids, oil change, or shop
supplies, or taxes.

This is a very generous estimate.  I did a timing belt on an 01 accord 4
cylinder the other day in about 2.5hrs start to finish.  Another 2 hrs to do
the rest of the required items.

I think you are getting hosed, especially if your car is a 4 cylinder.

Get a new mechanic.

That's a BUNCH.

Get a second opinion.

don't need to replace valves, simply adjust.

no water filter.

yes, you'll be getting the hose from this guy.  call for competitive
quotes from dealers and independent honda specialists.

If you have a V6, also add idler and tensioner pulleys for the timing
belt (Gates Timing Component kit is a good choice here), cam/crank oil
seals, serpentine tensioner pulley (just the pulley while the
tensioner assembly is off), valve cover gasket set, genuine Honda
coolant, and valve adjustment, it would seem like a good deal. I'd use
only NGK plugs and Honda thermostat only (these are among the few
parts I won't go aftermarket). What water filter?

A few months ago I paid a little less than $1,000 for timing and drive belt
replacement, new water pump, new front seals, new coolant, new transmission
fluid and brake fluid, new front brake pads, new air conditioner filters,
one new radiator hose, tire rotation, and a valve adjustment on my 2000
Accord SE. The work was done by an independent shop in Houston, and it was
all done well, as far as I can tell, except that they overinflated my tires.

I'd expect prices to be a bit higher in your location, but $1,500 sounds too
high for the work you mention.
