He used a Skill Saw with a fine blade and tacked down a guide board. 

Electricity, chemicals, scaffolding, spinning blades, etc. 

Some of them buy and fix.Non-gas push mowers take regular grinding and blade balancing maintenance to keep the blades sharp.

I have one rental that never used the bath fan and the humidity was so high in the house (in an arid area) that the ceiling fan blades warped.

You need a flat blade screwdriver to take care of the rest.If there is a deadbolt, you'll need a 7" angle grinder with a cut off wheel. 

Things can easily get lodged in garbage disposals and prevent the blades from spinning. 90% of the time that is the problem. 

A solution that he was happy with was that we simply removed the blades!  

Here In Md , I wont drop the blade for less than $ 125 and thats per push .

I change the A/C filter, check the disposal, fan blades, top of cabinets in kitchen and sink traps.  

The new one will be immeasurably better than anything that was there.And again, why do we need these fabulously rated windows for hurricanes, when the ones coming out wouldn't stop a blade of grass?
