What would be excessive voltage for a residential home for 120v. bulb?

I'd try 130v bulbs first, and check the manufacturer's can/trim/lamp combination ratings.

Oh, and I'd suggest keeping the hammer away from the fixtures.

We have found that vibration kills a lot more than people think; especially on a lower floor where people walk above. One house was so bad we put rough service bulbs in. Never blew another one there.

Too much heat in the recess can. Change bulbs to lower wattage rating, maybe change recess can's trim ring to a thinner design to allow more air flow.

Loose neutral.

These are a couple of ideas that might help.

What style lamps are you burning up?
Are they standard, pear shaped incandescents or are they spots or floods that are designed to reflect the light (and some of the heat) out of the can?
If they are standard incandescents such as you would find in a lamp, switch to the proper bulbs. If they are spots or floods, change to a lower wattage and make sure there is no insulation covering the back of the can.

Lost neutral, call fire dept.
Resistive connections, often the case...
Over-loaded circuit, rare...
Thermal sensor in over lamped can, often.
The cheapest lamp found on the internet, often.
Wrong dimmer, is also possible.
