KR, did you buy this car new or used? If new, has any work been done on the halfshafts before the boots started leaking? If used, have you any of the cars' maintenance and repair history?
If I were the tech working on this car, then I would hesitate to just tighten up the boot bands. It's said that ingress of dirt of any kind into the CV joint grease leads to failure. Maybe if I'd seen more reports of just tightening working fine, I'd go with this fix. But it sure does not come up here much, if at all.
OTOH, since clicking (outer joints) and clunking (inner joints) normally present before full failure, your approach might be worth a try. Whether a shop will agree to do only this is another matter. I guess they might.

Not that I am presenting myself as experienced as you. Just an observation.

When I read his message I gathered it was leaking from the boot/band join, which is different from leaking due to a split in the boot.
So, to elaborate: If the boots are split, replace the shafts. If the boots are leaking because the bands are insufficiently tight, replace the bands only.
And to the OP: CV joint boots split with regularity if not examined once in a while.

If grease is leaking from the boots, failure is likely not far away. You don't want them failing when you are driving down the highway. How long they'll last is hard to say, but point is, you want some peace of mind.
Your garage is right about just replacing the half-shafts. Reason: "Simply" re-packing is expensive, because the tech first has to take off the half shaft, then remove the boot, then thoroughly clean (and CV joint grease is about the thickest grease-based lubricant you'll see on a car), then re-pack. Major time in labor. Also, rebuilt half-axles have become plentiful, forcing down their price. IIRC boot quality has improved since 1996, so this may be the last half shaft replacement the car needs.
To see how competitive your shop is, check prices for half shafts for your Accord at Majestic Honda (probably around $150 per half-shaft), Napa Auto Parts and Autozone (closer to $75 per half-shaft). Insist on OEM from your garage, though that may be automatic, since one half shaft from one model of Honda does not exchange generally with that of another model. Compare prices.
Figure labor of a couple hours? That's a rough ballpark. Lots here have done the job, so check back for how long they think this should take.
I disassembled a CV joint a year or so ago in an automotive course, then reported on current practices and the thinking behind them for repairing CV joints.

96 EX Accord w 150k miles. On right inner & outer & left inner cv joints there is a grease leak from the ends of the boots. Boots are good & the boot clamps look ok. Why/how is grease getting out? No typical bad cv joint symptoms yet. Garage recommended new half axles - apparently nobody changes just boots anymore because of the labor costs. Before I go that route I'll get a lot more miles out of these - at least until they start clicking. I've not heard of grease leaking from good joints/boots. It's the vertical sling out pattern on the facing & backing surfaces & right where the boot/clamp there is seepage. Any ideas?
