Hi, calling all chimney experts

We live just outside Philadelphia and received an estimate from a chimney company to PCR clean (when we asked how bad it is, he said it was roughly creosote build up stage 1.5), apply HeatShield due to some cracks and shifted flue tiles, and use smoke chamber spray. We have 1 fireplace/chimney. The total cost of the job would be about $5200 with the full description and breakdown below:

PCR Cleaning, Heat Shield and Smoke Chamber Spray: ____ was at your home on 12/15 to perform a cleaning and inspection of your chimney. Upon inspection, creosote buildup was observed in the chimney. We recommend performing a Poultice Creosote Removal (PCR) cleaning of this chimney. This will be done over two visits. On the first visit, we will drop a sponge from the top of the chimney to the base of the flue. We will then pour the PCR down the chimney and pull the sponge up using a winch. Once the PCR cures, we will return to remove any residual debris. Shifted flue tiles were also observed in the chimney, which can allow smoke to escape the flue. At this time we will perform the Heat Shield procedure. This is done similarly to the PCR cleaning, but reseals the cracks and shifted flue tiles using insulated concrete that can withstand temperatures up to 3000 degrees. Furthermore, cracks were observed in the smoke chamber. We recommend resealing these cracks using smoke chamber spray. This spray is applied using a pressurized cannister.

The prices on this estimate are contingent upon agreeing to all proposed tasks simultaneously.

What we are curious about is if this seems really steep or reasonable as we don't have much experience with this. Keep in mind, we already paid about $100 for an inspection. We just don't want to be taken advantage of if this seems like a ridiculous price or oversell.

Thanks and appreciate any help!
