Lining a Wood Stove
Question- Here is an interesting question about using a Wood Stove that came into Ask the Chimney Sweep
With a fireplace insert, would it be practical to start by just dropping in a new metal flue liner, to TRY to stop the smoke from coming back into the room? (It’s an old home, therefore I am guessing the mortar MUST be getting weak by now, and it will be time for a fix.)
It’s the only fireplace there is. Furnace in basement is turned off. Won’t be turning on at all…might this cause any problem? Previous owners had installed a heat pump, high on wall, in same room as fireplace insert.
(There’s an attic space above the room that has the insert.) Cracking a window doesn’t seem to help. Therefore, I have to assume that the insert worked properly, at least at some point, it seems like the previous owners were there for many years, and had a big supply of wood. Any ideas what it should cost to have chimney person put in a metal liner (in WA State)?
Answer – Greetings Mr. Frustrated,
I’m going to try and save you a lot of grief. First of all, I would call a member of the National Chimney Sweeps Guild to find a chimney sweep in your area to clean your chimney. In addition to this, it is very important that they do a “video inspection” with a closed circuit camera.
Today prices may cost you apx $200 -$350. Most of all, after sweeping the chimney of all lose sweepable deposits, not gummy grazed or tarry creosote as this would be addressed as a separate issued video inspection needs to be completed the service person will be looking to document, scorched burn marks, missing mortar joints, and possible cracked or broken terra-cotta flue tiles.
*Power Sweeping, a fireplace with a spinning brush, mounted on extendable rods has proven to be the very best method to reach all of those difficult nocks in crannies that are hiding up in the smoke chamber.
If you have experienced a chimney fire, it may be covered as a Sudden Occurrence Insurance claim.
Now let’s talk about the Stainless Steel (SS) chimney flue lining systems. I know of no wood-stove insert manufacture today, that doesn’t require installing a stainless chimney liner with some type of UL tested insulation material.
These thermal blanket materials have two purposes, first is to provide clearance to combustible that may be in the chimney system and a second is to keep the hot gasses drafting up the chimney flue pipe properly.
All of the stove manufactures, that I’m aware of now require a SS liner to be same size in square inches, as the on the opening of the outlet on the stove. We only will take on a relining job if it is going to be installed all of the way to the top of the chimney flue system.
Estimated price for a SS liner will depend on the installation approach, degree of difficulty, size (6” or 8”) and the actual length of the SS a liner tneeded . Most installation today call for a 6” liner and may cost between $2,500 to $4,500.
We have switched to this newer HomeSavers Pre-Insulated HomeSaver Ultra stainless steel pipe
