Frequently Asked Questions
Should I burn a test fire in my Longmont fireplace before the inspector arrives?
No, you should never burn a test fire right before your appointment. For safety and accurate camera visibility, your fireplace and flue must be completely cold and free of hot coals or smoke for at least 24 hours prior to our arrival.
Is it worth upgrading to a Level 2 video inspection for my older home in Longmont?
Yes, a Level 2 video inspection is always worth it, especially for older homes across Longmont or during real estate transactions. It reveals hidden cracks, liner gaps, and creosote buildup deep inside the flue that standard visual checks from the room simply cannot catch.
Do I really need to clear furniture and rugs away from the hearth?
Yes, clearing a three-to-four-foot perimeter around your hearth protects your rugs, furniture, and decorations from soot dust. It also gives our technicians unobstructed space to safely set up drop cloths, ladders, and diagnostic video equipment.
How often should Longmont homeowners schedule a professional chimney inspection?
The Chimney Safety Institute of America recommends scheduling an annual chimney inspection and sweep every year, particularly before the heavy heating season begins in late fall across Northern Colorado.
