After getting two estimates for chimney install and not being overly impressed with either, i've decided to do the install myself . From what i can gather the local installers generally charge you twice what the material costs then add about half or more of that amount on top for the labor. The estimates i recieved were around $1800.00 to $1900.00 for a through the ceiling install. I've ordered the nessecary 6 inch duratech cathedral ceiling kit along with the class A duratech chimney and double wall dvl stove pipe for around $600.00.
The main reason i decided to do it myself was neither installer wanted to cut through the ceiling joist in order to do a straight up shot on the chimney, instead wanting to install two 45's on the stove pipe. The other reason was both installer only wanted to install 4 foot of class A chimney. From everything i've read on the forums it is best to have a straight shot on the chimney and pipe to lessen creosote build up and the nc-30 manual calls for 15ft. minimum from floor to top of chimney to aquire the correct draw. From floor to ceiling measures 7 ft. so in order to do it right i needed at least 8 ft of class A. The ceiling joists are 24" on center so i plan on building a temporary support brace on each side before cutting the one joist then building the frame for the support box plus any additional bracing thats needed.
The question i have is why did both installers want to use the to 45's and why only 4' of chimney? Is there anything wrong with how i have planned the install? Any tips appreciated.
