The small gap left around the chimney pipe
The collar is meant to sit close to the chimney pipe without being fastened or sealed to it. The same installers manual calls for a gap of one eighth of an inch around the flue pipe and carries a fire-risk warning against caulking the pipe to the chase top collar.
That warning surprises homeowners who have seen tar or silicone packed around the pipe. We remove that kind of improvised sealing, leave the gap the instructions describe and rely on the storm collar above it to keep rain out. Following the instructions is safer than improvising at the top of a chimney.
Keeping the air space around the pipe open
Factory-built chimneys are installed with a required air space between the pipe and anything combustible. The manual for one widely used system calls for a two-inch clearance to combustibles and building insulation around its chimney. That space has to stay open when a chase top is replaced.
While the cover is off, we look down into the top of the enclosure for insulation, debris or nesting material pressed against the pipe. Anything that does not belong there is noted and removed where it can be reached safely, and deeper problems inside the chase are explained on the estimate.
Looking after a new chase cover
Once the new cover is in place, a look from the ground after heavy storms is usually enough. Watch for a cover that has shifted, new rust marks on the siding or water where it did not appear before. Keeping branches trimmed back from the chase stops leaves piling up on the cover.
Do not climb up to adjust the cover or the storm collar. If something looks wrong, call and describe it. NFPA safety guidance recommends having chimneys inspected every year, and the chase top is part of that check.
Chase cover or masonry crown
Not every chimney top is a chase cover. A masonry chimney built of brick or block usually ends in a crown of concrete or stone around the flue, while a framed chase around a factory-built chimney ends in a sheet-metal cover. The two fail in different ways and call for different repairs.
You do not need to know which you have before calling. Describe what you can see from the ground, whether the chimney is sided like the house or looks like brick, and we will confirm the construction during the free inspection before recommending any work.
