Stainless steel chimney liner installation in College Park

What a relining estimate should list

Our written relining estimates list each part of the job, so you can compare them fairly with any other proposal. If a line is missing from a quote you received elsewhere, it is worth asking whether that part was left out or simply not written down.

• The liner product, diameter and length
• Insulation, and whether it is required or optional
• Top plate, liner cap and any extension
• The tee, adapter or other base connection
• Cleaning, tile removal and other preparation
• Separate lines for crown or masonry repairs

What the insulation wrap is made of

The insulation wrap one maker specifies is a half-inch, foil-faced ceramic fiber blanket of a set density, secured with a stainless mesh sleeve. Substituting another material can take the installation outside its listing.

We use the insulation the liner's instructions name, and we record it on your paperwork. Poured or other insulation types exist for some systems, and when one is proposed, the estimate names it and the listing it belongs to.

Replacing an older metal liner

An older metal liner can corrode, separate at its joints or collapse, particularly if it was never suited to the appliance. Replacing it starts with understanding why it failed, so the new system avoids the same cause.

We remove the old liner, check the flue behind it and size the replacement to the appliance you use now. The old liner goes with us, and its removal is shown as its own line on the estimate.

Writing down the clearances we checked

Clearance to combustibles is one of the things NFPA 211 asks an inspection to look at. On a relining job, we record where we could confirm the airspace, where we could not and how that affected the insulation decision.

That record answers the question for anyone who looks at the chimney later, from the next sweep to a buyer's inspector, without anyone having to repeat the same climb into the attic.
