Our house is now going on 1 year old. Since built, the electrical system has been "glitchy". The electrician has been back several times to fix things like the bathroom fans that trip the GFI's, or the light switch that arced and tripped the circuit breaker. My question involves the light switches. There are random cases of visible sparks from various switches throughout the house. Also, the switches are often "crackly" ,without a visible spark, when flipped. Since the builder warrants everything for a year, am I out of line to demand that ALL the light switches be replaced with something of a better quality? I think the current situation is dangerous to say the least, but my previous inquiries to the electrician were met with indifference. If they should be replaced, should I get someone else to do it? Thanks so much for any replies.
