Hey there! I am a new member but have lurked in the past. First off I want to say thanks so much to everyone who answers with their expertise. I don't always understand the answers I see here but it is clear a lot of professionals/folks with lots of experience take the time to answer questions from those of us with little experience- so thank you!

My husband and I recently decided to convert one of our gas fireplaces to wood, as we have six acres of woods and plenty of access to firewood. We figured we would have a professional line our chimney and possibly also install a wood stove, or maybe tackle the installing of a wood stove ourselves if it seemed pretty straightforward. I called around to numerous chimney are fireplace specialists, but we were out of their range (In the Piedmont of NC, but fairly rural area). We settled on a general contractor to come out and give us a quote on the job. it is a one story existing masonry chimney. He measured the chimney but did not remove the metal plate covering it's opening above the gas logs, nor did he get on the roof and look down the chimney. He gave us a quote of $3860 to line the chimney with a 6" metal pipe and install a wood stove for us. He also made it clear he would have to get on the roof and inspect the chimney first, and $3860 is if no issues were found. I am a bit taken aback at the price, as my husband and I had our chimney lined in our old home in Pittsburgh, PA that was two stories, needed an extender and a cap, and included a much nicer liner with a lifetime warranty for $2400 (about 4 years ago). If this is the going rate I think we will either have to try to do it ourselves or give up. I suspect this is an extremely high quote though and maybe I should keep looking for a contractor willing to do it. Any thoughts? Anyone do this work in the Piedmont of NC?

could be very straight forward and relatively easy for you guys to do this yourselves. the chimney is mostly inside the house, one story, so i don't think you need an insulated liner. i did my own years ago. used a fixed stainless pipe down to the fireplace damper area, with a flex piece with a coupler through the damper. hooked up my own stove. put a stainless top plate on the chimney with a pipe cap. had job done the same day.

look online for places that sell the whole package, like rockfordchimneysupply.com

Again. Insulation requirement is not determined by whether your chimney is internal or external. Insulation is first and foremost a safety measures taken to prevent heat transfer through the masonry structure to adjacent combustible material. It is needed in almost every case because the required clearances to combustibles from the outside of the masonry structure are almost never there. For an internal chimney like this 2" would be needed. External only need 1".

Ontop of the safety issue you also get performance gains internal or external.

That does sound a bit high. Installing the liner may be simple or may not be there are many variables.

Oh and your lifetime warranty is only for the lifetime of the liner. That can be anywhere between 15 and 30 years it is preset by the manufacturer

Can someone explain the difference between an external and intetnal chimney,. An external still touches the house on one side.

An internal chimney is completely surrounded by the house envelope. It is internal to the house structure.
 
For an estimate I think it is high, but this is peak season. Around June-August it could come in much lower. I would do some more shopping.

Is the general contractor NFI or CSIA certified? Sounds like they are treating it as a PIA job and pricing it accordingly, maybe they will sub it out?

Are you handy? If so you can do it DIY if you are up to the task and taking on the potential pitfalls, plenty of youtube videos out there and install threads on here to learn from.

No, not NFi or CSIA certified, just a general contractors license. My understanding was he/ his company was going to do it as I asked about a timeline and he mentioned needing to complete an addition they were working on.

I think we will do it ourselves. Watched some videos last night and took off the metal plate that was screwed on at the bottom of the chimney, and it looks like a completely clear and easy shot to the top. Thanks for the encouragement!

Thank you for the advice. We will insulate!

thank you for the encouragement! It looks like a very easy install after doing a little research. We will do it ourselves for sure. Looks like it will save us about 3,200 dollars!
 
It appears the woodwork might be too close to a stove. Be careful with clearance to combustibles!

I would question the quality you are getting if you are only paying $660 for an insulated liner and required fittings.

I haven't ordered anything yet but in my cursory searching that seemed about what they cost. I was looking at Rockford Chimney supply. Do you recommend a product/supplier in particular? I probably only need about 20 feet (Also haven't measured yet!).

I just priced a 20' light wall insulated insert kit from them it was $829. And that is just light wall which is the thinnest liner you can use. You could save a little by getting a liner and insulation kit and insulating yourself.
 
Do you already have a stove/insert?
No I don’t already have a stove/insert. Looks like I might not be able to alter my mantle because my house is under historic agreement. I’m thinking a Vermont Castings Aspen could work with the mantle.
