comment Will standing topped off tree trunks work for holding up a building structure?
Till the roots rot and then you have no structure. And dead tree roots start rotting pretty quickly. No way you're going to "rot-proof" them.

comment How to fix the chemical damage on my wood cupboard?
Strip down to wood and refinish. You've just got to finish what you've started. Don't use oven cleaner as the stripping agent.

comment Which cylinder door lock shield design is most secure?
Door and casement are the weak spots, nobody's going to bother drilling a lock if they want in, even in the country where they'll be undisturbed. There are a lot softer spots for entry than the door. An alarm system with glass breakage detectors is actually more safe than any door lock you can buy. Defense in depth if you're really concerned.

comment What can be used to fill holes on top of a lamp fixture?
Ventilated cans must remain ventilated. Closing the holes doesn't convert them to closed can IC rating.

@wallyk - Most of that will be fixed back east when the next New Madrid earthquake cluster strikes.

I am also concerned because he cut my rebar and the footer is not really tied into the block. Where in the world is this located?

comment Can I plug my 40 ampere stove into a 30 ampere receptacle?
40A breakers need to have the full circuit wired appropriately. Make sure the cable to the outlet is sized to handle 40A, the outlet should be changed to a 40A to reflect that. And no, unless the poof was because one of the contacts in the socket failed under load (burning, melted plastic, scorched prongs on plug), the socket wasn't why the stove died.

comment How to keep a block wall from blowing out at the bottom
To prevent water pressure, buried block walls should have a perimeter drain and gravel backfill on the outside of the wall. If it's so structurally unsound that it can't support the roof, tear it down and start from scratch with a reputable builder that knows how to reinforce cinder-block walls. Retrofitting a masonry wall, especially in earthquake country is going to end badly, no matter what you do. Soft courses that low in the layer will never go away (or rather will in the first good quake fail spectacularly).

comment What could be causing my electric hob to leak voltage?
Good time to have a look at the wiring insulation when you open it up. If any of the insulation looks suspect, go for replacing the whole unit. And yes, if the element control has a plastic case, the switch shaft is supposed to be completely insulated. Any voltage appearing on it means it's permanently past its service life. It would have to be filled with water to leak voltage to the shaft.

comment Can I upgrade existing T12 fluorescent fixtures to T8 just by replacing the ballast and bulbs?
Heh, the two tube fixtures are easy, follow the wiring diagram on the ballast. I had some two-tube hanging shop lights with a good fixture but a really cheap ballast (why they were so inexpensive). They used the standard ballast mounting, so it was easy to convert them from $25 to $50 fixtures by spending $14.50 plus tubes. No more flickering, weird starts, dead ballasts and old, inefficient tubes.

At $16 ballast cost per fixture, ballast costs weren't enough of a concern if we're talking about quality, built-in fixtures. If you're talking about those ultra-cheap hang from the ceiling things, maybe.

comment Central air compressor fan reflects sunlight into house. What can I do about it?
Removing the grill and painting matte black is about as professional as you can get unless you move the unit. We had to do similar on a fan in a non-negotiable location. For some of us, the strobing is worse than annoying, visual epilepsy events aren't fun.
