Looking for a Mason

It rains in our attic, this time through the chimney. It used to rain through the roof, cast iron vent pipe *and* the chimney, but now it's just coming in through the chimney after a new roof and many calls back and forth to the roofer over a period of years (until the figured out that the old cast iron vent pipe was cracked). I am sick if it raining in my attic.

I have an Angie's List membership but cannot for the life of me find a mason to call back. One finally did, only to tell us that the Masons are apparently slammed with work due to the crazy flooding we had a couple of months ago. He did finally come out and look at our chimney, which according to him doesn't need a lot of work (of course, he never came in the house so I'm not sure how he would know that). He's booked through November and said at that point it would be too cold to do the work, and suggested we give him a call next spring.

I don't know, I'm not a mason, but if it's raining in my attic I take that to be not a good thing. Am I being unreasonable?

Does anyone have a good reference for a Mason who does work in Waltham?
