Keep Your Home Safe and Beautiful With Professional Chimney Services

Your chimney plays a critical role in both the safety and structure of your home. Over time, exposure to harsh weather, freeze-thaw cycles, and regular use can lead to cracking, leaning, loose bricks, and deteriorating mortar. If left untreated, these issues can cause major problems—structural damage, water leaks, and even fire hazards.

  • Chimney inspections

Common Chimney Issues We Repair

If you notice any of the following signs, your chimney may need professional attention:

  • Cracked or missing mortar
  • Leaning or separation from the home
  • Loose or spalling bricks
  • Crumbling stone or brickwork
  • Water stains on walls or ceilings
  • Poor draft or smoke backflow
  • Rusted or missing chimney caps
  • Visible gaps at the roofline or flashing


These problems often worsen over time, especially in cold, wet climates like ours. Addressing them early can prevent more costly repairs down the road.

Chimney Rebuilds Done Right

When damage is too extensive for minor repair, we offer full or partial chimney rebuilds. We carefully deconstruct and rebuild the structure using high-quality masonry materials that match your home’s original character. Our rebuilds are reinforced for structural integrity and designed to handle Minnesota’s extreme weather conditions.



We follow all local codes and safety standards, working closely with homeowners and contractors to ensure each project is completed correctly—from venting and flashing to final finishing.

Tuckpointing for Chimney Maintenance

One of the most common chimney repairs is tuckpointing, which involves removing deteriorated mortar joints and replacing them with new mortar matched to your existing brick or stone.


Benefits of tuckpointing include:

  • Preventing water infiltration
  • Strengthening the structure
  • Extending the life of your chimney
  • Restoring a clean, uniform appearance


Our masons use careful techniques to blend new mortar seamlessly with existing masonry, maintaining both function and aesthetics.
