Our Process

How we replace a chase cover in Markham

What orange streaks on the siding tell you

Orange or brown streaks that begin at the top of the chase and run down the wall usually point to the cover. Rust forms where water pools on top, and each rain carries some of it over the edge. The streaks often show up well before a hole opens, which makes them a useful early warning.

If you see them on a chase in Markham, call (645) 465-4122 and ask for a free inspection. Replacing a rusting cover before it perforates keeps the job to the metal and spares the wood beneath it.

Fewer seams on the new top

Every seam in a chase cover is a place water can work into. The Majestic manual calls for all seams to be caulked, and a cover formed with as few joints as the chase size allows gives the sealant less to do.

Many single-pipe chases take one formed sheet with a joined collar. Larger chases may need seams, and where they cannot be avoided we lap and seal them so water runs over each joint and away from it. Our specialists also keep seams out of the path water takes toward the collar, where a failed joint would do the most harm.

Choosing a finish that suits the house

A chase cover is visible from the street on many homes, so its appearance matters along with its function. Bright galvanized and stainless sheet dull as they weather, and some homeowners prefer a painted finish that blends with the roof or trim.

We go over the finish options with you before ordering. Paint changes how the cover looks, but the slope, the raised collar and the drip edge remain the parts that keep your Markham chase dry. If you choose paint, we explain which coating suits the metal and when it may need touching up, so the finish keeps looking right.

Gaps that let birds and animals into the chase

A cover that has pulled away from the siding or rusted through at a corner leaves an opening into the enclosure. Birds, squirrels and insects can use it to get inside the chase, where they are hard to reach and can disturb insulation and framing.

If you hear activity inside, keep the fireplace unused and mention it when you book. Any animal is dealt with first, lawfully and without trapping it inside, and the new cover then closes the gap. Our specialists look down into the chase once the cover is off, so no nest or animal is sealed inside.
