Quick AnswerRepointing is the process of grinding out old, crumbling mortar joints across the full height of the chimney and packing them with new mortar, matched in color and mix to what's already there. It's broader in scope than a targeted tuckpointing repair, which patches just the worst spots — a full repoint addresses joints that are starting to fail but haven't cracked through yet, so you're not calling us back for the next section down the line six months later. Ohio's freeze-thaw cycles are hard on mortar specifically, since water gets into hairline gaps and expands, so most Cleveland-area chimneys need this every fifteen to twenty-five years depending on exposure.
What’s Included
This is a full-structure repoint, covering every course of brick on the chimney rather than just the section that's visibly crumbling. Mortar fails gradually, and by the time one section is bad enough to notice, the joints around it are usually not far behind, so we treat the whole chimney at once.
- Mechanical grinding of deteriorated mortar joints to a consistent depth across the entire chimney, removing old material without chipping or cracking the surrounding brick.
- New mortar mixed to match the strength and permeability of your original mortar, since packing modern high-strength mortar into an old chimney can trap moisture and crack the brick faces instead.
- Mortar color matched to your existing joints as closely as possible, so the repointed sections blend in rather than reading as an obvious patch.
- Joints packed and tooled to match the original profile, whether that's a struck, concave, or flush finish, so the repair looks consistent with the rest of the chimney.
- A full inspection of the brick face during the grinding process, so any spalling or loose brick we find gets flagged before we seal it behind new mortar.
- Cure time and weather protection as needed, since new mortar needs the right conditions to set properly rather than being rushed on a cold Cleveland afternoon.
Signs You Need This
- Mortar joints that are crumbling, powdery, or missing in multiple spots
- You can scrape mortar out of a joint with a fingernail or screwdriver
- Small plants or moss growing in the mortar joints
- Visible daylight or gaps between bricks
- Efflorescence, the white chalky staining that means water is moving through the wall
Our Process
Full inspection
We check mortar condition across every face of the chimney, not just the section you called about, to scope how much actually needs to be repointed.
Mortar matching
We match new mortar to the color, mix, and joint profile of your existing masonry before grinding begins, so the finished work is consistent top to bottom.
Grinding out old mortar
We remove deteriorated mortar to a consistent depth across the chimney without damaging the surrounding brick, clearing the way for a proper bond.
Packing and finishing
We pack new mortar into every joint, tool it to match the original profile, and protect the work while it cures.
How Much Does It Cost?
Repointing is priced by the total square footage of mortar joints being redone, chimney height and access, and how closely the mortar needs to be color-matched to older or harder-to-source brick. Because we're treating the full chimney rather than a single problem area, it's a bigger job than a spot tuckpointing repair, but it means we're not back out here for the next failing section next year. You'll get a flat-fee written estimate before any grinding starts, and that number doesn't change once work begins. If we find brick damage underneath the old mortar that needs more than repointing to fix, we'll quote that separately rather than adding it to your bill without asking.
FAQs
Tuckpointing repair targets the worst-looking section of mortar and patches it. A full repoint addresses every joint across the chimney, including ones that look fine now but are on the same deterioration timeline, so you get one consistent fix instead of recurring spot repairs.
Mismatched mortar is one of the most common giveaways of a rushed repair, and it's avoidable. We mix mortar to match your existing joints so the repointed sections don't stand out against decades-old brick.
It varies with exposure and the original mortar mix, but most chimneys in our service area need a full repoint every fifteen to twenty-five years. Ohio's freeze-thaw cycles are hard on mortar specifically, since trapped water expands and pushes joints apart from the inside.
