Question DetailsAsked on 7/9/2014

How much should it cost to reline a chimney with Heatshield cerfractory?

I was provided a quote of 2700 by a local reputable chimney co to seal my chimney liner with Heatshield due to corrosion in the morter joints, and would like to know if this is an average price for the job.The chimney is a standard 2 story unit.

$2700 is certainly within the normal range for a job like that. Most of our jobs like that run $ 2500 to $3500 depending on chimney height and size. If additional work is required than the total price could be higher.

A recent (2017) quote provided to me was $2,675.00 for the HeatShield "Cerfractory" sealant treatment. NOTE: This was accompanied by recommendations for HeatShield Smoke Chamber Sealant ($1,250) which is an expandable foam that coats the walls of the smoke chamber(I'm assuming that is your chimney, minus the flue) and recommendations to waterproof the external portion of your chimney ($459.00). I addition, a chimney cap and "CrownCoat" sealant over the chimney "crown" (why is this NOT part of the chimney??) added ($325.00) to the bid. Total for chimney treatment estimate: $5,190.00). I am, further, researching the benefits of of all of these processess.
