Water leaks around a Northglenn fireplace often start unnoticed but can lead to spalled bricks, damaged flues, and dangerous mold. A proactive chimney sweep and waterproofing before Colorado’s freeze-thaw cycles begin is the best defense. Schedule an inspection this summer to catch cracks and gaps early.
A chimney inspection is your first line of defense against Northglenn’s seasonal storms
A chimney inspection is a thorough visual and functional check of your flue, liner, masonry, and flashing to spot cracks, gaps, or deterioration before water can enter. In Northglenn, where summer hail and winter freeze-thaw cycles stress masonry, an inspection should include a moisture meter reading and a close look at the crown and cap. The Chimney Safety Institute of America recommends an annual inspection, but in Northglenn’s climate, consider a spring inspection to catch winter damage and a fall inspection to prepare for snow. Schedule your inspection today and avoid costly surprises when the first freeze hits.
Spot these 3 Northglenn-specific signs your chimney is already leaking water
In Northglenn, water often shows up as white efflorescence on bricks near the roofline, damp spots on the hearth, or a musty smell in the fireplace room. Another red flag is crumbling mortar joints or missing chunks of crown—a common issue after hailstorms typical of the Front Range. If you see rust on the damper or water pooling in the smoke shelf during a summer storm, your chimney is already compromised. Don’t wait for winter to address these issues; a summer chimney sweep and waterproofing can save thousands in repairs.
Should you repair or replace your Northglenn chimney crown before winter?
If your chimney crown has hairline cracks or missing sections, repairing it with a high-strength mortar mix is often sufficient for Northglenn homes. However, if the cracks are wider than a credit card or the crown is crumbling, replacement is safer. A cracked crown lets water seep behind the bricks, leading to spalling and structural damage. In Northglenn’s climate, a crown replacement costs between $800 and $1,500, while repairs average $200–$400. Contact us for a free estimate before the first snow to avoid emergency repairs.
Is your Northglenn chimney cap doing enough to keep water and wildlife out?
A chimney cap isn’t just a screen—it’s your home’s first defense against Northglenn’s summer hail, autumn leaves, and winter ice dams. If your cap is rusted, missing, or too small, water, birds, and even squirrels can enter your flue. A custom stainless steel cap with a mesh screen costs $150–$300 and includes a lifetime warranty against wildlife intrusion. In Northglenn, where wind-driven rain is common, a poorly fitted cap can funnel water directly into your chimney. Upgrade your cap today before the next storm.
Do you really need to waterproof your Northglenn chimney masonry every 3–5 years?
Yes—especially in Northglenn, where freeze-thaw cycles can crack unprotected bricks in a single winter. Waterproofing creates a breathable barrier that repels water without trapping moisture inside. A quality silane/siloxane waterproofing treatment costs $200–$400 and lasts 3–5 years. Skip this step, and you risk spalled bricks, damaged flues, and costly relining. Book a waterproofing appointment this summer to lock in protection before the first freeze.
How to check your Northglenn fireplace flashing for hidden leaks this summer
Flashing—the metal seal between your chimney and roof—is a common leak point in Northglenn homes, especially after hail or high winds. To inspect it, climb onto your roof (safely) and look for gaps, rust, or caulking that’s cracked or missing. If the flashing is loose or corroded, resealing with high-temperature silicone costs $100–$250. For severe damage, a full flashing replacement runs $400–$800. Don’t rely on roofers unfamiliar with chimney work—hire a licensed chimney sweep in Northglenn to ensure a watertight seal.
When to call a Northglenn chimney sweep for emergency leak repairs
If you notice water dripping into your fireplace during a storm, a sudden increase in draft issues, or white efflorescence spreading across your hearth, it’s time for emergency repairs. In Northglenn, these issues often stem from a cracked flue liner, failed crown, or missing cap. Delaying repairs can lead to mold, structural damage, or even chimney fires.

Frequently Asked Questions
Should I schedule a Northglenn chimney sweep before or after summer storms?
Schedule your chimney sweep after summer storms but before fall. Summer storms can dislodge debris and expose cracks, making them easier to spot during a sweep. A fall inspection ensures your chimney is ready for winter’s freeze-thaw cycles.
Is it worth waterproofing my Northglenn chimney if it looks fine now?
Absolutely. Northglenn’s freeze-thaw cycles can turn tiny cracks into major leaks overnight. Waterproofing costs far less than relining or rebuilding a chimney. Think of it as insurance against costly masonry repairs.
Do I need a chimney cap if my Northglenn fireplace hasn’t leaked before?
Yes. Even if you haven’t seen leaks, a cap protects against hail, debris, and wildlife intrusion—common in Northglenn. A missing cap voids many homeowner insurance policies if water damage occurs.
How much does it cost to fix a leaking chimney in Northglenn, CO?
Repairs range from $200 for minor caulking to $2,000+ for full relining or crown replacement. The cost depends on the damage’s extent and whether you need masonry work, waterproofing, or a new cap. Get a free estimate to see what your Northglenn home needs.
