Hello, we just bought a home that was built in the 60’s. I want to be sure the fireplace is safe before my family useS it. We had a few companies come out and got a wide range of prices and advice. I’m not sure what to make of it all as this is the first time we have had a fireplace. We need a new liner. One company said the terra-cotta has to be broken up and removed before a liner scan be installed and the other two companies said it does not. Those same two companies said we also need a new liner for the boiler and new larger piping. The other company never asked to see the boiler. One said all the bricks need repointing or the chimney will collapse in two years, while another said just the top of the chimney needs repointing. And another company said just to spray with a waterproof sealer. Now out of these 3 companies each has a different price. ....11k, 6k, and $4800.00. I’m so unsure of who to trust! Any advice on how to proceed and if these prices seem reasonable?
