Minnesota's harsh freeze-thaw winters crack mortar, spall bricks, and destroy chimney crowns faster than almost any other climate. The Duct Badger repairs chimneys across Minneapolis, MN before small damage becomes a costly structural problem.
We handle every type of chimney damage common in Minnesota's climate — from minor mortar cracks to full crown rebuilds.
Minneapolis freeze-thaw cycles erode mortar between bricks. We grind out crumbling joints and repoint with fresh mortar — stopping water infiltration before it collapses the chimney structure.
A missing or cracked chimney cap lets Minnesota rain, snow, and animals inside your flue. We install and replace stainless steel caps that fit tight and last decades.
The chimney crown is the concrete slab at the top of your chimney — Minnesota's winters crack it fast. We repair and seal crowns to prevent water from getting inside the chimney system.
Spalling bricks flake and crumble from Minnesota's freeze-thaw moisture cycles. We replace damaged bricks and apply breathable sealant to prevent further deterioration.
Cracked firebricks and damaged mortar inside the firebox are a fire hazard. We repair the firebox and smoke shelf so your Minneapolis fireplace burns safely and efficiently.
A cracked flue liner allows dangerous combustion gases to seep into your home. We inspect and repair clay or stainless steel liners to keep your Minneapolis home safe.
Minnesota has one of the most chimney-damaging climates in the country. Water freezes in small cracks, expands, and forces them wider — every winter. Brick and mortar that looked fine in September can be visibly damaged by April.
Left unrepaired, chimney damage accelerates. What costs a few hundred dollars to repoint today can cost thousands to rebuild in two years. Water also travels down damaged chimneys into your home's walls, ceiling, and attic — causing mold, rot, and structural damage far beyond the chimney itself.
Don't wait until damage is visible from the street. These signs mean your chimney needs attention now.
Fast, professional, and done right the first time — every Minneapolis repair job.
We inspect your chimney top to bottom — exterior brickwork, crown, cap, flashing, firebox, and liner — before recommending any repair.
We give you an upfront written quote covering exactly what's needed and why. No upselling, no surprises.
Our licensed technicians complete the repair with professional materials rated for Minnesota's climate — not patching products that fail in one winter.
We walk you through the completed repair with photos so you can see exactly what was done and feel confident the job is finished properly.
Real jobs from real Minnesota homes.
