Since you say you are not handy , I'm assuming tools and ladders are in short supply. If so, on the bird problem, I'd call a chimney sweep or fireplace shop and tell them your problem. Either one of those people will know someone or be able to come out and fix the problem. They will in all likelyhood bring a chimney cap(spark arrestor) with them which needs to be installed.
Yes ive called my contractor and he is sending out his "chimney guy" to put a screen over the top..
But we still dont know what to do about the birds on top off the vent hatch. Guess ill just have to open it and let the nest fall into the fireplace.. Try to chase the birds out the window like last time.
A chimney sweep sounds expensive...
Thanks guys!
