A chimney stands out in the open all year, taking rain, wind, sun and, in many places, hard freezes with no shelter at all. Sooner or later something on it needs attention, whether that is a loose cap, a tired mortar joint or a part inside the flue. If you searched for “chimney chase services”, this page gathers the questions homeowners in Port Moody ask most often about chimney chase repair, answered plainly so you can judge what your own chimney needs and what can wait.

Repairs matter because chimneys tend to fail slowly at first and then expensively. We regularly open up a chimney where a minor issue, such as a missing cap or one cracked mortar joint, was left alone for a few seasons. By then, water has soaked the bricks, rusted the damper or softened the wood framing beside the stack. Work at that stage takes longer and uses far more material. Catching the same fault early usually means a short visit and a modest bill. There is a safety side too, because a damaged flue or liner can let heat and smoke escape where nobody expects them.
A chimney’s parts fall into three groups: the weatherproofing outside, the flue liner inside and the working parts at the bottom. Weatherproofing means the cap, the crown, the flashing and the face of the bricks and mortar. The liner is the channel that handles heat and corrosive exhaust. Down at hearth level are the pieces people actually touch, such as the damper handle, the firebox walls and the ash dump door. On a prefab system, a framed chase and its sheet metal top replace the brick. When we diagnose a problem, we trace it to one of these groups first, because that decides what the fix looks like.
Rot inside a chimney chase almost always starts with water from above. A flat or rusted chase cover lets rain collect and drip down the inside walls, a cracked storm collar lets it run along the flue and gaps in siding or trim near the top let wind-driven rain in from the sides. Once the framing stays damp, wood softens and siding begins to bulge or stain. Leaks around the roof line can add to it. Anyone looking up “chimney chase services” after spotting swollen trim or dark streaks should have the top of the chase opened and probed, since rot is often worse inside than it appears.
A chimney chase cover should be replaced when it is rusting, sagging, holding water or leaking around the flue opening. Many original covers are thin galvanized steel and flat, so water pools on top, rusts the metal and eventually drips into the chase, leaving rust streaks on the siding below. A replacement is custom-sized to the top of the chase, usually in stainless steel or another durable metal, with a raised center or cross-break so water runs off and a drip edge that carries it past the siding. A storm collar and a cap finish the flue opening.
A chimney repair visit normally starts with an inspection to confirm the problem and check for anything related. The technician protects the area around the fireplace and, for exterior work, sets up ladders or roof anchors. Then the damaged part is removed or prepared, whether that means grinding out mortar, cutting away old sealant, unbolting a cap or opening a damper assembly. New materials go in, and the work is checked for fit and weathertightness. At the end you should see the finished work or photos of it and hear about anything else that turned up along the way.
We suggest once a year for most chimneys, with extra visits after anything unusual. A yearly look from the roof and up the flue shows us how earlier repairs are holding and whether anything new has appeared. Events that justify an extra check include a strong windstorm, hail, a lightning strike nearby, a roofer working around the chimney and any time an appliance is added or swapped. A chimney you never use is not exempt; some of the worst weather damage we find is on chimneys nobody has looked at in years, simply because no one noticed the warning signs inside.
Small chimney repairs, such as replacing a cap, sealing a crown or freeing a damper, often take a few hours. Mid-sized jobs like new flashing, a new chase cover or a fan installation usually fit into a day. Larger masonry work, including repointing an entire stack or rebuilding the section above the roof, can take several days, because mortar and concrete need time to set between stages. Weather adds to the schedule for anything done outside, since rain and cold delay masonry. Ask for an estimate of both working time and total calendar time before the job is booked.
Yes, a reroof is an ideal time. Roofers remove the shingles and flashing around the base of the chase, so any soft sheathing or damaged framing there is exposed and easy to repair. It is also the moment to replace a tired chase cover, since crews and ladders are already on site. Coordinate with the roofing contractor so the chase is sealed and flashed before the new shingles are finished around it. If you are planning a reroof and searching for “chimney chase services”, ask both companies who will handle the flashing so nothing falls between the two jobs.
Mention what the chimney is made of, what it serves and what you have noticed, because a few details on the phone save a lot of time on the roof. We ask which appliances use the flue, how many stories the house has and how steep the roof is. We ask what you have seen: a stain, debris in the firebox, a stuck handle, a rattling cap, smoke in the room. We ask when it started and whether a roofer or another contractor worked nearby recently. Two quick phone snapshots, one of the chimney top from the yard and one of the problem area inside, often tell us which parts and ladders to bring on the first trip.
