How Often Should You Get Your Chimney Inspected?

Wondering how frequently to schedule chimney inspections? This guide covers recommended inspection intervals for Colorado homeowners to ensure safety and efficiency.

As a Denver homeowner, maintaining your chimney is crucial for both safety and home value. Colorado's extreme weather conditions, from heavy snowfall to intense summer heat, can accelerate chimney deterioration. Understanding proper inspection schedules helps prevent costly repairs and dangerous situations like carbon monoxide poisoning or house fires.

Standard Chimney Inspection Frequency

The National Fire Protection Association (NFPA) recommends annual chimney inspections for all homes with fireplaces or wood-burning appliances. However, Colorado's unique climate conditions often require more frequent attention.

Annual Inspections Are Essential For:

• All active fireplace and wood stove users

• Homes with gas fireplaces or furnaces

• Properties with oil-burning heating systems

• Any chimney system, regardless of usage

At Colorado Chimney Sweeps, we've seen firsthand how Denver's freeze-thaw cycles can cause rapid deterioration in chimney systems that appeared fine just months earlier.

Factors That Increase Inspection Frequency

Heavy Usage

If you use your fireplace more than 40 times per year or burn more than two cords of wood annually, consider bi-annual inspections. Denver's long winters often mean extended fireplace use, leading to faster creosote buildup and increased wear on chimney components.

Age of Your Chimney

Chimneys over 20 years old in the Denver metro area should receive more frequent inspections. Colorado's high altitude and UV exposure can accelerate aging in masonry and metal components.

Previous Issues

If your chimney has had water damage, structural problems, or animal intrusions, schedule inspections every six months until issues are fully resolved.

Severe Weather Events

After significant hailstorms, heavy snow loads, or high winds common in Colorado, schedule an additional inspection to check for damage.
