Chimney relining details worth knowing in Midtown
What the chimney liner standard covers
UL 1777 is the standard for chimney liners installed in the field inside masonry chimneys. Its scope covers liners for certain gas-fired, oil-fired and solid-fuel appliances, fitted in an existing chimney or in place of clay tile in new construction. A liner listed to it carries a label that names the listing.
The same scope leaves some appliances out. Appliances that run with positive vent pressure or produce corrosive condensate belong to other vent systems. Read us the rating plate on your appliance when you call. It helps us confirm that a listed liner is the right family of product at all.
Insulation follows the listing, not a habit
Whether a liner needs insulation depends on the listed system and the chimney it goes into. Some systems require an insulation wrap over part or all of the run. Others arrive insulated from the factory. The listing also ties the liner's clearances to how it is installed.
We read the insulation requirement from the manual of the liner we propose. The estimate says whether insulation is included, what type, and why. Leaving it out to lower a price, or adding it where the listing does not call for it, is not a choice we make on your behalf.
Using the appliance after relining
After installation, the appliance's own manual governs how it is started and used. We explain which parts of the liner need no attention and which deserve a look later. Watch the early fires for smoke at the opening or an unusual odor.
If something seems wrong, stop using the appliance and tell us what you saw. We come back to check the connection and the cap. Our workmanship warranty covers how the liner was installed, and we explain what it includes when the job is handed over.
Weather and an open chimney during relining
Rain can interrupt relining work at the top, and an open flue lets water in. We plan the day so the chimney is not left open longer than necessary. Whatever the forecast, an open chimney is covered before we leave.
If weather stops work partway through, we explain what state the flue is in and when the job resumes. The fireplace or appliance stays out of use until the liner is complete. We tell you when it is ready to use again and what to watch for.

Liner installation answers in Midtown
How do you decide what size liner my chimney needs?
We start from the appliance manual, which states the flue size the appliance requires, and the code rule that a flue may not be smaller than the appliance connector. Then we check whether the passage can take that size along its whole route.
What happens to my damper when the liner is installed?
If the liner runs down to an appliance, the damper plate or frame may have to come out for it to pass. The estimate says whether the damper stays or goes, and any damper repair is priced separately from the liner.
Is a stainless liner suitable for any fuel?
Not automatically. The listing decides which appliances and fuels a liner may serve, and two stainless products can carry different listings. We name the listing in the estimate and match it to your appliance manual before anything is ordered.
