Summer is the ideal time for a ground-level visual assessment of your masonry and chimney cap. While you should never scrub the flue or climb on the roof yourself, checking for loose bricks and dampness prevents costly winter repairs.
Keep Ground-Level Brickwork and Mortar Intact
Walk around your Burnsville home and look closely at the lower masonry joints. If you see soft, crumbling mortar, note its location. You can gently brush away moss and debris from the exterior bricks to prevent moisture retention, but never apply sealant yourself; old brick needs to breathe. For concerns on structural cracks, check our guide on masonry repair questions. This visual assessment protects your home’s foundation. In neighborhoods like those served by Chimney Sweep in Lakeville, we see moss retains water that cracks brick when frozen.
Assess the Chimney Cap and Crown for Damage
Climb a safe ladder to eye-level with the crown, or use binoculars from the yard. Look for chips in the concrete wash or a missing/damaged cap that lets birds in. These entries cause damp drafts to flow down. Installing a new cap requires a pro, but identifying the gap is a perfect summer task. Ensuring these are tight prevents water from seeping into the flue liner during our heavy summer storms. If you see significant wear, browse our services for repair options before fall arrives. Keeping the top sealed is vital for extending the lifespan of your older chimney.
Manage Fireplace Ash and Draft During Off-Season
Even in July, ensure your firebox is clear of old ash, which holds moisture and can rust dampers. Open the damper occasionally for cross-ventilation to reduce the 'musty' basement smell common in older Burnsville homes. However, if you smell a strong, acrid odor, do not use the fireplace. Instead, contact us immediately. Keeping the hearth dry prevents liner deterioration during the humid months. This simple airflow management is the safest DIY task you can perform to ensure your wood-burning system remains fresh throughout the off-season.
Recognize Warning Signs That Require Professional Intervention
If you see white powder on the brick (efflorescence) or flaking faces on bricks, your chimney is trapping water inside. These are signs of internal moisture damage that a simple cosmetic fix cannot resolve. Never attempt to repoint high masonry or tuckpoint from a ladder yourself; these repairs require specialized height safety equipment. Review our pricing guide for standard service costs. Also, understand the critical safety differences detailed in DIY vs. Professional Chimney Cleaning. Recognizing these limits prevents voided warranties or severe injury from rooftop falls on uneven Minnesota roofing.

Frequently Asked Questions
Should I seal my brick chimney to stop water leaks myself?
No, applying waterproof sealant without professional assessment can trap moisture inside older bricks, causing them to spall and crumble during freeze-thaw cycles.
Is it worth paying for a sweep if I use my gas fireplace?
Yes, gas fireplaces produce corrosive byproducts that can eat away at older terracotta liners, requiring a specialized camera inspection to check for blockage or cracks.
Do I really need professional help if my mortar looks a little soft?
Yes, soft mortar is a sign of eroded tuckpointing that requires scaffolding and specialized tools to fix safely; delaying repair risks structural chimney collapse.
