Chase cover replacement by local pros in Belle Isle

Fastening the cover through its skirt

A chase cover is held by fasteners through its skirt into the framing on the sides of the chase, where water runs past instead of sitting. Spacing them evenly on every side keeps the skirt tight to the wall along its full length. Manufacturer instructions we have read also call for noncombustible spacers at the corners beneath the chase top. We use fasteners compatible with the cover metal and place them where the manual for your system puts them.

Comparing two chase cover quotes

Two quotes can both say chase cover replacement and describe very different jobs. Our estimate lists each of these items in plain language so a side-by-side comparison is easy. A lower price that leaves out the storm collar or uses a thinner sheet is a different job, even if both say chase cover.

• The metal and its grade, and the sheet thickness
• How the top is shaped to drain, and the collar height
• Skirt depth, drip edge and fasteners
• Whether the storm collar and cap are included
• How hidden damage under the old cover will be handled

Leaks at the base versus the top

Water can enter a chase at its top, through the siding or at the base where it meets the roof, and the cover addresses only the first. When stains appear low on the chase or on the ceiling right beside it, the base deserves a close look. We inspect both ends of the chase and tell you which one the evidence points to, so you do not replace a sound cover when chimney flashing repair is what the leak needs.

A pipe that leans out of plumb

Sometimes the pipe above the cover leans, pulling the collar and storm collar out of line and opening a gap on one side. The cause may be a loose support, a damaged section or an old impact. We note the lean and check what can be seen of the supports from the top. Straightening or supporting the pipe is chimney system work that must follow the manufacturer's instructions, so it is described and priced separately. A leaning pipe can also rub against the new collar, so the lean is addressed before or with the cover work.
