I have used Northeastern a couple of times, and they are professional, quick to respond and dedicated to performing quality work. I think the first time I called Northeastern was probably 10 years ago. They came after I'd had smoke in my basement when we turned our furnace on in October. I had had a different company come previously and line my chimney with a metal pipe (like your dryer exhaust pipe). That first company didn't install the liner the right way, which was why I had smoke in my basement. Northeastern fixed the problem immediately, and I could rest easy knowing my house was safe. I've used them ever since for any chimney issues or problems I've had.
