Looking for a chimney repair company recommendation
Hi all,
I have a chimney that seems to have bad liner that needs to be replaced. I have water dripping down my heaters flue and have some white sediment on the heaters flue from it as well as rust.
Looking for a recommendation for a specialist who can do an assessment and have the work done. Property located in NE Philadelphia
Any help appreciated.
Cheers,
Yuriy

Oh, hearing six appliances on that chimney I bet you are getting back-drafting through the chimney.
The various heaters need air to burn gas. If the volume of air getting to them is insufficient, intake air for combustion gets drawn in through available openings, and the chimney then has back-drafting being open to the outside.
Test it with some tissue or TP (OK TP is quite scarce and valuable during COVID-19), a single piece will do. While multiple appliances are firing, the tissue or TP should be held near the appliance hood, and you want to see how it flutters. If it gets sucked up toward the flue, that is expected (and you want that); if it is being blown back away from the flue then that is back-drafting.
Back-drafting can be solved by installing an air makeup kit to bring outside air to those appliances, so combustion intake air doesn’t have to be pulled through the chimney.
