GET YOUR WIRING TENDED TO *NOW*!!!
Our outlets were just pouting a bit and we wound up
with a house fire that destroyed our home in seconds.
(We had spent all morning in the kitchen with no sign
of trouble.
Less than three minutes after we left for the living room,
our appliances were molten sculptures,the minis were goo,
the dining room was ash and all glass in the house had
shattered out into the yard.)
We survived because we were two feet from the front door
when we heard the windows blow out and saw the flames entering the next room.
(The cats asleep in the bedroom died of smoke inhalation
without ever rousing.)
A close inspection is necessary because one patch of bad
wiring wasn't even on the blueprints.
The wiring had burned and extinguished itself several times,
had 'dead' outlets,sparking,brownouts,breaker tripping,etc.
for weeks before the fire.
The work the electricians did then helped but it wasn't
enough to correct all the dangerous areas.
We NEVER had anything as extreme as you're describing.
Don't waste time getting this fixed because an electrical
fire can take you out in less time than it takes to set off
your smoke detector or grab a phone that's beyond your arm's reach.
If you're in the room with the explosion,you'll never feel
the blast and if the lack of oxygen/presence of toxic fumes hits,you could die from that before you hear or smell the
conflagration.
That's too much peril to risk for your family.
I wish you the best at getting this dealt with before anything unfortunate occurs.
