A Level 1 chimney inspection is the standard visual check required annually for most Dunstable homes with a clean, accessible chimney. A Level 2 inspection is a more thorough, camera-assisted exam required after damage, a change in fuel type, or when buying/selling a home. Both are critical for safety and compliance with local codes.
What is a Level 1 chimney inspection?
A Level 1 chimney inspection is the foundational safety check every Dunstable homeowner should schedule annually. It’s a visual examination of the readily accessible portions of your chimney and venting system, performed from the rooftop down to the firebox. Our certified sweeps check for creosote buildup, blockages, cracks in the flue liner, and signs of deterioration in the masonry or chimney cap. We also inspect the firebox, damper, and smoke chamber for damage or excessive wear. This inspection meets the requirements set by the ((National Fire Protection Association (NFPA)|https://www.nfpa.org/)) for routine maintenance and is typically completed in under an hour for most Dunstable homes. If your chimney is straightforward—no recent damage, no fuel changes, and no obstructions—this is the inspection you need. We always provide a free estimate and a detailed report, so you know exactly what’s happening inside your chimney. Schedule your Level 1 inspection in Dunstable
When does a Dunstable home need a Level 2 chimney inspection?
A Level 2 chimney inspection is required when there’s a change in the way you use your chimney—like switching from wood to gas—or after an event that could compromise safety, such as a chimney fire, a major storm, or an earthquake. It’s also mandatory when you buy or sell a home in Dunstable, as part of a real estate transaction. This inspection goes deeper: we use specialized cameras to inspect the entire flue, including hidden cracks or deterioration that aren’t visible from the rooftop. We also check the attic, basement, and crawl spaces for signs of leakage or structural issues. In older Dunstable homes, especially those built before 1980, we often find unlined chimneys or damaged terra cotta liners that require immediate attention. A Level 2 inspection ensures your chimney meets current safety standards and protects your family from carbon monoxide and fire risks. Learn more about when to upgrade your chimney in Dunstable
How our white-glove team performs a Level 1 inspection in Dunstable
When you book a Level 1 inspection with us, expect a meticulous, no-cut corners approach. Our sweeps arrive in branded uniforms, equipped with HEPA vacuums and drop cloths to protect your home from soot and debris. We start by examining the exterior chimney for cracks, leaning, or missing mortar—common issues in Dunstable’s older neighborhoods like the historic center or along Pleasant Street. Inside, we inspect the flue from the firebox up, checking for creosote glaze, rust, or blockages. We test the damper operation and measure flue clearance to ensure proper drafting. Every inspection includes a free carbon monoxide test to verify your chimney isn’t leaking deadly gas into your living space. We leave your home cleaner than we found it, with a detailed report and photos of any concerns. All work is backed by a 100% satisfaction guarantee. See our full service list
What to expect during a Level 2 inspection in Dunstable homes
A Level 2 inspection is more involved, but our team treats it with the same care and precision. We begin with a Level 1 inspection, then deploy a chimney camera to inspect the entire flue liner, including sections hidden behind walls or in the attic. In Dunstable, many homes have chimneys that extend through multiple floors, making this step essential for spotting cracks or deterioration in the liner. We also check for proper clearance from combustibles, inspect the chimney cap for rust or damage, and look for signs of water intrusion in the masonry. If we find issues, we provide a clear, itemized estimate for repairs, including relining options for unlined chimneys—a common need in older homes near the Nashua River. All findings are documented with photos and shared with you before any work begins. Get a free estimate for Level 2 inspection in Dunstable

My chimney in Dunstable hasn’t been used in years. Do I still need an inspection?
Yes. Even if your chimney in Dunstable hasn’t been used in years, it’s still vulnerable to water damage, animal nests, or deterioration. Moisture is a chimney’s worst enemy, and a neglected flue can develop cracks or blockages that become hazardous when you finally relight the fire. We recommend a Level 1 inspection before any use, followed by a Level 2 if we find signs of long-term neglect. In Dunstable, we’ve seen chimneys in the center of town or near the Groton line collapse due to years of water infiltration. Don’t risk it—schedule an inspection today.

Frequently Asked Questions
My chimney in Dunstable has a slight tilt. Should I get a Level 1 or Level 2 inspection?
A Level 2 inspection is the right choice. A tilt often indicates foundation issues or masonry damage, which requires a camera-assisted exam to assess the flue liner and structural integrity. We’ll provide a detailed report and repair estimate to address the problem before it worsens.
Why does my Dunstable home’s chimney need a camera inspection every few years?
Camera inspections reveal hidden cracks, creosote buildup, or deterioration in the flue liner that aren’t visible from the rooftop. In Dunstable’s older homes, unlined chimneys or damaged terra cotta liners are common, making camera inspections essential for safety and compliance.
I’m selling my house in Dunstable. What inspection do I need for the buyer’s lender?
Most lenders require a Level 2 chimney inspection for real estate transactions. This ensures the chimney meets current safety standards and protects the buyer from liability. We provide a detailed report with photos, which can be shared with your realtor and lender.
Can I skip the Level 2 inspection if my Dunstable chimney looks fine from the outside?
No. External appearance can be deceiving. Hidden cracks, deteriorated liners, or blockages in the flue can’t be seen without a camera. The ((Chimney Safety Institute of America (CSIA)|https://www.csia.org/)) recommends Level 2 inspections after events like chimney fires or fuel changes, even if the chimney looks intact.
