Why Mendota Heights Homeowners Call Northwind Chimney Sweep for Chimney Repair
Homeowners in Mendota Heights call us because we treat a chimney like the system it is: flue, crown, flashing, cap and firebox all working together. We carry inspection, cleaning and repair in one place, so the team that diagnoses your problem is the same team that fixes it. Our technicians have up to 12 years of experience, and we work with professional-grade materials – DuraFlex, HeatShield, Gelco and Copperfield among them – not the hardware-store substitutes that fail early.
We also know this specific patch of ground. The heavy oak and cottonwood canopy over so many Mendota Heights homes loads flues with acorns, leaves and animal nests, and the clay tiles in mid-century stacks crack in our freeze-thaw cycles. That local pattern means we don’t guess at the cause; we check for the things this neighborhood actually produces. Nothing gets recommended without camera footage you can watch with us and judge for yourself. That’s the difference between an honest diagnosis and a sales pitch, and it’s why people here call us back.

Chimney Repair Companies in Mendota Heights
Chimney Repair Companies in Mendota Heights deal with a very specific kind of wear. Most homes here are 1950s to 1990s single-family builds on large wooded lots, many with exterior masonry chimneys that take the full brunt of our winters. When mortar goes soft or a flue loses its seal, a homeowner needs repair fast – before spring rain finds the gaps. Basic repointing typically runs $300 to $800 depending on the size of the job, while a damaged crown or flashing usually falls in the $400 to $1,200 range. Every price we give is set by a written estimate after we’ve looked at the stack.
What a Repair Visit Involves
A proper visit starts with inspection: we check the firebox, damper, flue and crown, and run a camera down the stack so you can see the condition of the tile. From there we document what we find, explain what can safely wait and what shouldn’t, and only then put together a plan. You see the problem before anyone quotes a fix.
Second-Story Flues and Long Driveways
Plenty of Mendota Heights homes have two-story rooflines and long driveways, and that shapes the setup as much as the repair. Multi-story flues mean taller ladders and careful staging, and animal nesting turns up more often on those upper stacks. We plan access before we arrive so the work goes cleanly and nothing gets rushed.
Chimney Masonry Repair in Mendota Heights
Chimney Masonry Repair in Mendota Heights usually means one of three things: spalling brick where water got behind the tile, mortar joints that crumbled through a winter, or a crown that cracked and is now leaking. Freeze-thaw cycles are hard on masonry here. Water soaks into the brick or mortar, freezes, expands, and pushes the surface apart, so a hairline crack in fall can be a spalling face by spring. Full tuckpointing typically runs $500 to $1,500. A crown rebuild or flashing repair is often $400 to $1,200, and waterproofing to protect the masonry afterward usually costs $300 to $700. Once we’ve seen the damage, the written estimate tells you exactly what’s needed.
Why Waterproofing Matters More Here
Our snowy winters and heavy spring rains are a two-part problem for masonry. The cold opens cracks, and the rain then drives water into them. A breathable waterproofing treatment on sound masonry slows that cycle dramatically and is far cheaper than rebuilding a chimney down the road. We apply it only after the mortar and brick are ready to receive it.
Repointing Before Rebuilding
Not every failing chimney needs to come down. If the brick itself is solid and only the joints have gone, repointing restores the structure for a fraction of a rebuild. A full rebuild is reserved for chimneys where the masonry core has lost integrity. We’ll tell you plainly which situation you’re in.
Trusted Brands We Service in Mendota Heights
We work with a curated roster of professional-grade chimney brands, and that matters when your repair calls for a specific product. DuraFlex flexible liners suit full relining projects. HeatShield ceramic resurfacing can extend the life of a liner without pulling it out, which saves both cost and disruption. Copperfield and Gelco cover liner components and venting hardware, including caps and dampers. We don’t claim to keep these parts stocked or on hand; instead we specify the right product for your flue and get it in without delay, so your repair isn’t held up waiting on the wrong substitute.
Common Chimney Repair Problems We See in Mendota Heights Homes
- Acorn and leaf load under the canopy. Overhanging oak and cottonwood drop acorns, twigs and leaves straight onto exterior crowns, clogging spark screens. That debris traps moisture and speeds crown cracking, so what looks like minor litter becomes a leak path.
- Raccoon and squirrel nesting on upper flues. Second-story flues are a favorite for wildlife here, and a nest left in place during heating season is a real fire and carbon monoxide risk. We remove them and cap the flue so it doesn’t happen again.
- Cracked clay tiles from freeze-thaw. In 1960s to 1980s homes, clay-tile joints open over the years, letting water and creosote seep behind the liner. It’s often misread as a simple cleaning issue until the camera shows the gaps.
- Undersized stacks venting new appliances. Original fireboxes and dampers were sized for open-hearth burning. When a modern insert or furnace is vented into that same stack, draft suffers and third-degree creosote glaze can form that no brush will remove.
The one thing that ties these together is the canopy. A Mendota Heights chimney sits under trees that shed all season, so you get a mix of creosote and organic litter that builds faster than in open-sky neighborhoods. And from mid-May through August, a staccato chatter echoing down the flue usually isn’t a draft problem at all – it’s chimney swifts nesting, and it needs handling before the heating season starts. That spring-to-fall window, not winter, is when this work actually gets done here.

AfterPricing for Chimney Repair in Mendota Heights, MN
We price by the job, and the written estimate is what sets the final number. To give you a sense of scale: repointing typically runs $300 to $800, crown or flashing repair $400 to $1,200, waterproofing $300 to $700, and a full chimney rebuild can reach $3,000 to $8,000 depending on height and how much of the stack has to come down. A HeatShield resurfacing or a DuraFlex reline is quoted separately once we’ve measured the flue. What moves the price is height, access, the extent of the masonry damage, and whether a liner is involved. The estimate itself is free, and nothing gets recommended that the camera footage doesn’t support. Say no to anything that can safely wait.

FAQs About Chimney Repair in Mendota Heights
That chatter is chimney swifts nesting in your flue, not a draft problem, and it does need attention before heating season. The birds are protected during nesting, so the timing of the removal and capping matters. A camera inspection confirms the nest and any debris, and we cap the flue once it’s clear so it doesn’t recur. Call (844) 834-2087 for an exact quote – estimates are free.
Crumbling joints on an otherwise sound chimney usually call for repointing, not a rebuild. Freeze-thaw cycles attack the mortar first; if the brick behind it is still solid, repointing restores the structure for a fraction of a rebuild, typically $300 to $800. A rebuild is only warranted when the masonry core has lost integrity. We’ll show you which one you’re facing on camera. Call (844) 834-2087 for an exact quote – estimates are free.
You can’t reliably tell by looking up from the firebox – only a camera inspection shows whether creosote has glazed into a hard third-degree layer. Third-degree creosote is baked on and a brush won’t remove it, which is where relining or resurfacing comes in. We show you the footage before recommending anything. Call (844) 834-2087 for an exact quote – estimates are free.
A cracked crown lets water straight into the flue, so the repair starts with a camera check to see how far the moisture has traveled. From there a typical fix rebuilds the crown with a proper overhang, repairs flashing where it’s failed, and treats the masonry with breathable waterproofing. Crown and flashing work usually runs $400 to $1,200. Call (844) 834-2087 for an exact quote – estimates are free.
Yes, even a lightly used chimney should be inspected once a year. Under the canopy here, animal nesting and organic debris build up whether you burn or not, and a neglected flue can develop problems that have nothing to do with fire frequency. The inspection is cheap next to the cost of discovering a blockage mid-winter. Call (844) 834-2087 for an exact quote – estimates are free.
