Cleaning Blockages in Chimneys and Liners
Blockages in chimneys and liners caused by nesting birds, squirrels and racoons, are a common occurrence and need to be cleaned.
Missing raincaps or poorly designed raincaps often allow birds, squirrels and racoons to enter the chimney to nest and live. Many, if not most, raincaps, are not well designed to keep birds and squirrels out. If this is the case, after the blockage is cleared, it is prudent to install a properly designed raincap to keep the same problem from happening again.
Also, most gas liners are constructed from aluminum. While being relatively inexpensive, aluminum liners are easily torn and subject to corrosion from acids in the gas exhaust. We have seen aluminum liners chewed right off at the top by squirrels wanting to nest and many simply break open from corrosion. If this is the case the liner itself will need to be replaced, preferably with more durable stainless steel.
The Main Sweeping and Cleaning, “How We Clean” section applies. The information below is specific to blockages.
- The work area is very well covered as blockages can be messy.
- Birds, squirrels or racoons that are present need be encouraged to leave the chimney. This can be a big process.
- The blockage is carefully removed, usually from both top and bottom, with special tools and brushes designed for the job.
- If a lined system the liner may need to be replaced.
- Disinfectant is used where possible and prudent to reduce lingering odours and possible nasty bug issues
- The work area is swept and vacuumed and left clean.
