Lee - here's an article on chimney liners: I recommend liners - they are safer and improve energy efficiency by reducing the temperature the actual chimney will heat up to. But they are expensive, so you must weigh the benefits against the costs. Also - here is an article giving definitions to all the parts of a chimney: Finally, I agree with John PO - get multiple estimates if you're thinking of getting major, expensive work done - many companies will give free estimates, so check in to that.

Has anyone used Stove Doctor in Pasadena,Md area?

My ceiling in my daughters room keeps leaking. I have done everything possible n the money wow. The leak is next too the chimney. But I have had everything done n still does the same I need help

need help in finding reutable chimney cleaner/repairer in the Brockton,Ma. area

When ever having estimates done PLEASE PLEASE have three estimates done. The BBB and google are great ways to find reviews and so on. Do not hire out of state chimney guys! We are having a problem in MA with NY scam sweeps leaving $5000 estimates on all the jobs. Sweeps Luck!!!

I was told my entire chimney needs to be re-done, however when the finance company would not extend the credit to cover the job, the contractor reconsidered their offer to only fix the 2 feet from the top of the chimney and 3-4 feet at the bottom of the chimney. Their reasoning was that the middle was proctected from the outdoor elements and that it wouldn't need as much attention. My reply was then you lied about needing the entire chimney needing to be fixed. How much can a complete chimney job cost? Is it safe to only fix part of the chimney?

I had my home dormed and the chimney extend. However, the contractor did not extend the liner. Now I'm having CO2 back up. What I do?

I need someone to repair my flu on my fireplace

The wall above the fireplace (base assembly) in our living room has bowed and while it seems strong I am very concerned.

My house is about 60+ years old. I was told I need a chimmy lining. How do I know if I actually need them. Is it not safe to have a chimney cap if the chimney do actually need a lining. Thx!
