Our Chimney Repair Services
Whether you are dealing with a minor leak or significant structural wear, our team provides expert masonry and flashing solutions:
-
Chimney Flashing Repair & Replacement: The most common source of chimney leaks is failing flashing, the seal where the chimney meets the roof. We use professional-grade, weather-resistant materials to ensure a water-tight bond. -
Mortar Joint Pointing: Over time, mortar can crumble due to moisture absorption and freezing. We remove damaged mortar and replace it with high-strength, weather-resistant materials to restore the stability of your chimney stack.
-
Waterproofing & Sealing: We apply breathable masonry sealants that prevent water penetration while allowing the chimney to "breathe," extending the life of your brick and mortar.
-
Custom Chimney Wrapping: Give your aging or weathered chimney a clean, uniform, and modern look. We wrap chimneys in heavy-duty, weather-resistant materials that instantly upgrade your home's curb appeal.
Why JM Northshore for Chimney Repairs?
Roofing and chimney work are inherently linked. A contractor who doesn't understand the roof system will often fail to properly integrate the chimney flashing, leading to future leaks.
-
Integrated Roofing Knowledge: Because we are GAF Master Elite roofing experts, we understand exactly how a chimney must be integrated into your roof system to remain leak-proof, regardless of snow accumulation or ice buildup.
-
Precision Flashing Techniques: We don’t rely on quick-fix caulking. We use industrial-grade flashing systems that provide long-term protection, ensuring that water is diverted away from your roof-chimney intersection.
-
Proactive Inspection: We don’t just fix the chimney; we inspect the surrounding shingles and roofing deck to ensure that the moisture hasn't caused hidden damage to your roof structure.
-
Safety-First Professionalism: Chimney work involves significant height and structural risks. Our team adheres to strict safety protocols, ensuring the job is done right and safely.
Chimney Repair Frequently Asked Questions (FAQ)
It could be either, or both. Often, water enters through failing chimney flashing or degraded mortar joints and travels down into the attic. We perform a diagnostic inspection to identify the exact point of entry, whether it is the flashing, the brickwork, or the roof shingles – and provide a targeted repair plan.
We can perform many chimney repairs throughout the year. However, certain masonry work (like repointing) requires specific temperature conditions for the mortar to cure properly. We will assess your chimney’s condition and advise on the most effective time to perform the repair to ensure a durable, long-lasting fix.
Given Northwestern Ontario’s extreme temperature swings, we recommend having your chimney flashing inspected every 3 to 5 years, or whenever you have roof maintenance performed. Catching a small crack in the flashing now can save you thousands in water damage repairs later.
We focus on structural repair and professional flashing systems. If your chimney has suffered major structural failure, we can provide an assessment and help you determine the best course of action.
