Landlords are required to make routine repairs in a timely fashion, no matter how small. Major repairs that compromise day-to-day living for tenants should be a top priority. If your landlord does not respond to your first request, then send a second request with a repair deadline. After all, you are paying to live there. You are entitled to a clean, functioning household. If major repairs go ignored for more than five days, send your landlord a request letter to work on the repairs yourself but stating you shall need it deducted from your monthly rent.
