Help finding advice with problem landlords in USA?

I have just moved into a rented accomodation in Cambridge, USA. The house has many problems such as, windows don't close properly, the gas leaks in the kitchen a little. The agency I rent from have said to me that they will not do anything to correct these problems. Who can I speak to, to get advice or support? ThanksHelp finding advice with problem landlords in USA?
The windows were there when you moved in. If they are older they are not plum anymore and you need to weather strip.





The gas leak is an issue, the power company should be out to look at it within a few hours of you calling them. They will pinpoint exactly where the leak is without charging you or your landlord. Who pays to fix it will depend on where it is and what caused it to start leaking. It is unusual for the lines to fail without being damaged, but it could just be a faulty washer.Help finding advice with problem landlords in USA?
I don't know about the windows, you may be stuck with them, but if there is a gas leak, if you smell gas ar all, call the gas company, they will be out within the hour, at least that's the way it is in this city. A gas leak is dangerous and could cause a fire or explosion. If there is a leak, the landlord will be required by law to fix the problem. I recently had a gas leak in my rental. The problem was the kitchen stove and it had to be replaced.
