When mortar joints crumble, water gets in and your chimney starts falling apart from the inside. Our chimney mortar repair Pleasant Grove UT crews grind out failed joints, pack in fresh mortar, and seal the stack so Utah County freeze-thaw cycles stop eating your brick. We handle everything from a single chimney mortar fix Pleasant Grove homeowners call about after a hard winter to full chimney tuckpointing on older Pleasant Grove homes. Same-day estimates, code-correct work, and a workmanship warranty on every job.
chimney mortar repair Pleasant Grove UT is the process of cutting out deteriorated mortar joints and repacking them with fresh mortar so the brick, stone, or block above your firebox stays locked together. Mortar is the sacrificial part of a chimney: it is softer than brick on purpose, so it takes the weather damage first. When joints recede past about 3/8 inch, water sits in the gap, freezes, expands, and pushes the brick face off. That is spalling, and once it starts, it accelerates every winter until the stack needs a rebuild instead of a repair.
Pleasant Grove sits in a freeze-thaw band along the Wasatch Front where chimneys take a beating. Winter nights drop below freezing, afternoons climb back above it, and that cycle runs dozens of times between November and March. Add summer UV baking the crown and fall rain driving sideways into south- and west-facing stacks, and mortar in this area ages faster than most homeowners expect. If you have been searching chimney mortar repair Pleasant Grove UT near me after noticing grit on the roof or a joint you can poke with a screwdriver, you are in the right place.
Every chimney mortar repair job we run in Pleasant Grove includes the core work below. Add-ons like crown rebuilds, liner replacement, or flashing repair get quoted separately so you can see exactly what each item costs and decide what to do now versus later.
We cut failed mortar back to sound material, roughly 1/2 to 3/4 inch deep, using a grinder and hand chisels. Surface smearing is not tuckpointing and it fails in one winter, so we do the slow version that lasts.
We mix Type N, Type O, or refractory cement to match your chimney's original mortar in color and hardness, then pack each joint full depth with a masonry trowel. Joints get tooled to shed water, not catch it.
While we are on the roof, we check the crown for cracks and the cap for rust or missing screens. Small crown cracks get sealed on the spot; larger crown damage gets quoted as a separate repair.
We run an inspection camera down the flue to check for cracked tiles, corroded liner sections, and creosote buildup. If the liner is damaged, we tell you before we seal anything up.
Once the mortar cures, we apply a breathable waterproofing sealant like ChimneySaver to the stack. It keeps liquid water out while letting vapor escape, which is what stops the freeze-thaw cycle from starting over.
We magnet-sweep the yard and driveway for nails and mortar chips, haul away debris, and hand you before-and-after photos plus a written workmanship warranty. Most jobs wrap in a single day.
We get on the roof, photograph every joint, and probe the mortar with a masonry trowel to find soft spots. A moisture meter tells us how deep the water damage goes, and an inspection camera checks the flue and damper while we are up there. You get a written scope with photos, usually within 24 hours of the call.
Good tuckpointing means removing bad mortar, not covering it. We cut joints back to sound material, roughly 1/2 to 3/4 inch deep, using a grinder with a masonry wheel and hand chisels in tight corners. This stage takes the longest, typically two to four hours on a standard single-flue chimney.
We mix mortar to match the existing color and hardness, then pack it in with a masonry trowel and finish each joint with a jointing tool. Type N mortar is the standard for most Pleasant Grove chimneys; softer Type O goes on older, softer brick. Joints get tooled to shed water, not catch it.
We repair or reseal the crown with a flexible crown sealant, then apply a breathable waterproofing sealant like ChimneySaver over the cured mortar and brick. Breathable matters: it keeps liquid water out while letting vapor escape, so you do not trap moisture inside the stack.
We check every joint by hand, run a smoke pen to confirm draft, and magnet-sweep the yard and driveway for stray nails and mortar chips. You get before-and-after photos and a written workmanship warranty. Most jobs are done in a single day, weather permitting.
Purpose-built equipment, used by trained technicians — so the job is done accurately the first time.
Used to pack mortar into ground-out joints and tool each joint to a water-shedding profile. The jointing tool is what gives the finished repair its weather resistance.
Cuts failed mortar out of joints to the correct depth, roughly 1/2 to 3/4 inch. Hand chisels finish tight corners where the grinder cannot reach.
Measures how much water is inside the masonry so we know whether the damage is surface-level or has soaked deep into the chimney structure.
Runs down the flue to check for cracked clay tiles, corroded stainless steel liner sections, and creosote buildup that we cannot see from the roof.
Confirms proper draft after the repair by showing how smoke moves up the flue. If draft is weak, we know there is a blockage or liner issue to address.
Clears creosote and soot from the flue so we can inspect the liner properly and so the chimney is safe to use after the mortar work is done.
Applied after the mortar cures. It is breathable, so it keeps liquid water out while letting vapor escape, which is the key to stopping freeze-thaw damage.
Joints were eroded 1/2 inch deep across the whole stack, with three spalled brick faces on the south side. The homeowner had grit in the gutter every spring and had been told the chimney needed a full rebuild.
We ground out and repacked 84 joints with Type O mortar matched to the original color, replaced the three spalled bricks, and sealed the crown. Total job time was one day. The chimney has been through two winters since with no new spalling.
Water was running down the flue and staining the ceiling during every storm. Two other companies had quoted a full chimney replacement. The actual problem was failed mortar above the roofline plus a cracked crown.
We repacked the failed joints, resealed the crown with flexible crown sealant, and applied ChimneySaver waterproofing. Total cost came in under $1,000, and the leak stopped completely. The homeowner avoided a $7,000 rebuild.
A newer home with a tall two-flue stack showed early joint cracking on the west face after two winters. The homeowner caught it early and wanted it fixed before it spread.
We ground out and repacked 22 joints with Type N mortar, sealed the crown, and waterproofed the full stack. Job took about five hours. Two winters later, no new cracking and no spalling.
Mortar failure shows up in a handful of predictable ways. Here are the ones we see most in Pleasant Grove, what happens if you ignore them, and how we fix each one.
Ask a pro →We grind out the failed mortar to sound material, repack with matched mortar, and tool each joint to shed water. Most single-flue chimneys are done in one day, and the repair stops the crumbling cycle before it reaches the brick.
We trace the leak with a moisture meter and inspection camera. Most Pleasant Grove leaks come from failed mortar, a cracked crown, or bad flashing, and we fix the actual source instead of smearing sealant over the symptom.
We cut out the spalled brick, replace it with matched units, and repack the surrounding joints. Then we waterproof the stack so the new brick does not go through the same cycle.
We find where the water is entering, repair the mortar and crown, and apply a breathable waterproofing sealant. The staining stops coming back once the moisture path is closed.
Most chimney mortar repair jobs in Pleasant Grove run $400 to $1,800 in 2026, depending on how many joints need work and how high the stack is. A small repair on a single-flue chimney often lands near the low end; a full tuckpointing job on a tall two-flue stack sits at the top. Crown sealing and waterproofing add $250 to $600 if you bundle them.
A chimney mortar fix Pleasant Grove homeowners hire us for includes grinding out failed joints, repacking them with matched mortar, tooling the joints to shed water, and cleaning up the work area. We also inspect the crown, flashing, and liner while we are up there. If the crown is cracked or the flashing has failed, we quote that separately so you can decide what to fix now and what can wait.
Yes, if the brick itself is still sound. Repacking joints with fresh mortar stops the water intrusion that drives freeze-thaw spalling, which halts the crumbling cycle. If brick faces have already popped and the stack is losing structural strength, you may need brick replacement or a partial rebuild instead. We tell you straight which one your chimney needs after the inspection.
Most single-flue chimneys take one day, usually four to eight hours of on-site work. Larger two-flue stacks, heavy joint erosion, or a crown rebuild can push it to two days. Cure time matters too: fresh mortar needs about 24 to 48 hours before it sees heavy rain, so we schedule around the forecast and seal once the mortar has set.
