1. What Is a Chimney Inspection? (And Why It’s Your First Step Before Repair)
A **chimney inspection** is a thorough check of your flue, liner, masonry, and roof connections to spot damage before it worsens.

Book a certified inspection today to avoid overpaying for unnecessary repairs.
2. 7 Warning Signs Your Mendota Heights Chimney Needs Repair (Check These Now)
Don’t wait for a **chimney fire** (like the one that damaged a **South St. Paul home last winter**)—spot these red flags early: 1. **Cracks in the masonry**: Hairline cracks are normal, but gaps wider than **1/8 inch** let moisture in, weakening bricks over time. Mendota Heights’ clay soil expands in spring, stressing foundations—check for vertical cracks after heavy rains. 2. **Rust stains on the roof or siding**: Rust around the **chimney crown** (top) or **flashing** (metal seal) means water leakage. In Dakota County’s humid summers, this corrodes metal fast. 3. **Smoke or odors in your home**: If smoke backs up into the room (or you smell gas when lighting the fireplace), your **damper isn’t sealing** or the flue is blocked—common in older homes near **Hennepin Avenue**. 4. **Soot or creosote buildup**: Glossy black creosote (like tar) on the fireplace walls is **Stage 3 buildup**—a fire hazard. The **NFPA** calls this a leading cause of chimney fires, especially in wood-burning fireplaces. 5. **Animals nesting inside**: Birds, squirrels, or raccoons leave **droppings, nests, or chewed materials** in the flue. A Mendota Heights family near **94th Street** had a raccon block their chimney last fall—costing $800 to remove debris and repair damage. 6. **Crumbling mortar joints**: If mortar looks like **sand or powder**, it’s failed. Repointing (replacing mortar) is a **$300–$800 repair**—cheaper than rebuilding a collapsed section. 7. **Water stains or leaks in the ceiling**: Yellow/brown stains near the ceiling where the chimney meets the roof mean **leaks from a cracked crown or missing flashing**. Fix this before winter, or you’ll face **$2,000+ in water damage repairs**. **Pro Tip**: Snap photos of these signs and email them to your chimney sweep—they’ll use them to give an accurate quote.
