The Question Behind Every Chimney Call
Almost every chimney inspection comes down to one question: can this be repaired, or does it need rebuilding? The answer matters enormously — repairs cost a fraction of rebuilds, but repairing a chimney that's structurally failing is money thrown away. Here's exactly how we evaluate it.
Test 1: The Brick
This is the deciding test. We check the brick units themselves — not the mortar, the brick. Are the faces solid, or are they flaking, popping, and crumbling (spalling)? Sound brick with bad mortar: repair candidate. Deteriorating brick: no amount of repointing fixes it, because the units themselves are failing. You can't mortar your way out of bad brick.
Test 2: The Depth of Mortar Failure
Surface mortar deterioration is normal aging — repointing handles it. But we probe the joints: if the mortar is gone deep — an inch or more, or through the full wythe — the wall's integrity is compromised beyond what repointing restores. Deep failure across large areas points toward rebuild.
Test 3: Structural Movement
Is the stack leaning? Are there stair-step cracks running through courses? Has a section shifted? Movement means the structure has failed, not just the surface. Repointing a leaning chimney is cosmetic — the lean continues and the new mortar cracks with it.
Test 4: The Repair History
Has this chimney been patched before — and are the patches failing? A chimney on its third round of spot repairs is telling you the underlying masonry is done. Each patch cycle costs money; at some point the rebuild is cheaper than the next three patches combined.
What We'll Tell You
After these four tests, the answer is usually clear — and we'll give it to you straight, with photos of what we found. If a repair will genuinely hold, we'll recommend the repair; rebuilds are bigger jobs, but we'd rather have your trust than your rebuild money. If it's beyond repair, we'll show you why rather than just saying so.
