Chimney Repair in Isanti & Cambridge, MN
Straight up Highway 65 from the north metro. Older brick, wood heat, and chimneys that stand out in the open with nothing to break the wind.
Free written estimate on any chimney we can see. We send photos of what we found on your roof, not a verbal guess.
Isanti County housing runs from century-old town homes with original brick stacks to rural builds from the last thirty years. What they share is exposure: not much around these chimneys to slow the weather down.
Exposure is the whole story
Wind-driven rain gets into any open joint, and a hard overnight freeze expands it. Do that a few hundred times and the joints are gone; do it a few hundred more and the brick faces come off. The section above the roofline goes first every time, because it's the only part with no help from the house.
What that means for the repair
Caught early it's a repoint and a new crown, and it isn't an expensive day. Caught late the top section has to come down and be rebuilt. The difference between those two is usually two or three winters, which is exactly why we'll come look at it for nothing.
Old brick needs old-style mortar. Repointing century-old masonry with modern high-strength mortar destroys the brick, because the joint stops being the sacrificial part. We match strength as well as color.
Ordinary repairs, no permit
Crowns, repointing and above-the-roofline rebuilds are ordinary repairs under Minnesota Rule 1300.0120. Nothing to file with the city.
What we do up here
Chimney Crown Rebuilds
The concrete cap on top is the part that fails first in Minnesota. We tear the cracked crown off and pour a new one with a real overhang and a drip edge so water leaves the chimney instead of running down inside the brick.
Tuckpointing & Repointing
Freeze-thaw pulls the mortar out of the joints a little more every winter. We grind the failed joints out and repoint with mortar matched to the brick, so the chimney stops drinking water.
Above-the-Roofline Rebuilds
When the brick above the roof is spalling, leaning, or has open joints all the way through, we take the chimney down to sound masonry and rebuild it. Plenty of chimney companies sub this out. We self-perform it.
Flashing, Chase Covers & Waterproofing
Rusted-through chase covers, failed storm collars, tar-smeared flashing. We replace the metal, correct the flashing, and seal the masonry with a vapor-permeable water repellent.
Straight answers
- Do you actually come up here or is this just a web page?
- Highway 65 is one of our two regular routes between Little Falls and the north metro. We're through here on purpose, not by exception.
- Can you do the work in winter?
- Masonry needs temperature to cure, so full rebuilds and poured crowns are warm-season work. We can tarp, stabilize and stop water any time of year, and we'll tell you honestly whether yours can wait for spring.
- Do I need a permit to have my chimney tuckpointed or the crown rebuilt?
- Almost never. Minnesota Rule 1300.0120 exempts ordinary repairs from the permit process, and repointing joints or pouring a new crown is ordinary repair work. We aren't opening a wall, moving a beam, or altering a vent. Relining a flue is the one that changes the venting system, and that one does get a permit in most cities. We tell you which side of that line your job falls on before we start, in writing.
- How fast can you get here from Little Falls?
- We run the Highway 10 and Highway 65 corridors on purpose, so north metro work gets grouped into the same days rather than squeezed in one at a time. Call and we'll tell you the next day we're already going to be in your area. That's usually the fastest and cheapest way to get on the schedule.
- Do you take on the masonry other chimney companies turn down?
- That's most of what we do up here. Plenty of sweeps will clean and inspect all day and then sub out anything that needs a trowel above the roofline. We self-perform crown rebuilds, repointing, and top-half rebuilds, which means a sweep, a roofer or an inspector can hand us the masonry and keep their customer.
- What does it cost?
- Crowns, repointing, and rebuilds are priced off what is actually up there, so we photograph the chimney and send a written number before anyone commits to anything. No trip charge to look at it.
