I've tried repeatedly to log in to my BP account on the app but it always gives me a "your login or password was incorrect" message.

Here is the list of problems: The front door barely opens, NONE of the doors close correctly, garage door has been replaced but the electrical still needs work, no doorbell, no fire alarms or carbon monoxide alarm, no working outside lights, a severe mice infestation (who have now raided my brand new couch), no insulation in the mudroom because of a door installed incorrectly, which is allowing cold air into the house and raising my heating (propane!)

We did one recently that was a 1970's build where the drain from the kitchen sink was incorrect and it had water in it all the time - it separated when we pulled the sink causing us to pull the wall apart to repair but the slope was not correct.Do you have a slab or basement / crawl space that allows you to easily get to the plumbing? 

Drano is well known but I wouldn't use it for my lawn, well known means nothing if your using a tool incorrectly.
