Chimney Repair in Hastings Ranch That Fixes the Gap, Not Just the Stain

Few people call us saying the crown has a crack. They call because there is a brown ring on the ceiling, because grit keeps landing on the grate, because something rattles in the flue on windy nights, or because the fireplace smells like a wet ashtray after rain. Each of those has a short list of likely causes, and our job is to go down that list on the roof and inside the flue until we find the one that matches. A ceiling stain beside the chimney usually means the roofline metal or a crown crack. Grit in the firebox points at crumbling mortar or a flaking flue tile. A rattle is often a loose cap or a damper plate. The smell is soot plus water, which means water is getting in somewhere above it.

We take photos at each step so you can follow the reasoning, and we test where we can, for example running water at the roofline to see where it comes through. Only once we know the cause do we price the repair, and we price that one repair, not a package. In Hastings Ranch, many of the chimneys we work on are on older houses where the crown was poured thin, the top course of brick has soft mortar, and nobody ever put a cap on the flue. Those three things together let in rain, leaves and animals, and they tend to fail together. Fixing the gap at the top often solves problems that showed up much lower down.

The crown is the concrete or mortar slab on top of the chimney. When it cracks, water runs straight down into the brick and the flue. Small cracks can be sealed with a flexible crown coating. If the top slab is crumbling, thin or flat, we chip it off and pour a new one whose edge sticks out past the brick, so rain falls onto the roof instead of running down the face. Flue tiles crack from heat, age and earthquakes; one or two damaged tiles near the top can sometimes be replaced, while a run of cracked tiles usually means a stainless liner is the better answer. Mortar joints that have gone sandy are ground out and repointed, and spalled bricks are swapped out.

Every one of those repairs is priced after we have seen it, in writing, before work starts. We do not quote repairs over the phone, because the same symptom can come from a twenty-minute fix or a two-day job, and guessing either way does you no favors. What we can promise is that the quote will say what we found, what we will do, what it costs and what it does not include. If the top of the flue is open, we will also suggest a cap, since a new crown with no cap above it is still a landing spot for leaves and an open door for birds and squirrels.
