Need help with non-responsive landlords!?

no you are not at a point where you can break your lease. Every state in the US requires that a landlord be contacted in writing (that means paper and pencil not e-mail) of any repairs that need to be made. The vast majority of states give the landlord 30 days with which to respond. You will need to put your grievances in writing and send them via the US postal service return receipt requested which will start the 30 day clock. After which time some states give the tenant latitude in performing repairs yourself of calling someone and deducting it from the next month's rent but this should only be done if it's put in writing in your letter and the landlord still doesn't respond.
