Fireplaces, boilers, furnaces, and water heaters venting into masonry chimneys should be inspected every year.
Our CSIA certified chimney technicians use a camera to inspect chimney flue liners, mortar joints, and the chimney structure. We utilize specialized equipment to access all areas of your chimney system, including masonry chimneys serving gas and oil appliances.
During a chimney inspection, a certified chimney tech can identify damage, plan necessary repairs, and recommend whether cleaning, repair, or relining is needed. This is especially important after replacing a boiler, furnace, or water heater.
Chimney inspections are recommended once a year for wood-burning fireplaces and for gas and oil appliance chimneys. We offer 3 levels of inspections:
- Level 1: If you're using your chimney the way it was built, this is the level of inspection needed. Requires a basic visual inspection of the chimney structure, smoke chamber, fireplace, and chimney exterior.
- Level 2: If changes have been made to your system including a change in fuel, a new appliance, or suspected venting problems, a level 2 is recommended. A level 2 inspection includes all inspection methods used in level 1 but also includes inspection of other areas such as the attic, crawl space, and basement.
- Level 3: If you have experienced a chimney fire or suspected chimney fire, a level 3 inspection is required. These are special inspections performed to access any hidden area, repair, or replacement of damaged areas.

What We Inspect
- Firebox, smoke chamber, and damper
- Flue liner condition, joints, and sizing
- Vent connectors, thimbles, and appliance entry points
- Chimney crown, cap, flashing, and exterior masonry
- Draft performance, blockage, and venting safety
Why Gas & Oil Systems Need Annual Inspection
- Acidic exhaust can quietly damage clay liners and mortar joints
- Moisture problems often start before homeowners notice them
- Appliance replacements can leave the chimney oversized for the new unit
- Annual inspections help catch carbon monoxide and spillage risks early
- A Level 2 video scan may be needed after appliance or fuel changes
Chimney Inspection FAQs
What is the difference between a Level 1 and Level 2 inspection?
Level 1 is a basic visual inspection, while Level 2 adds access to attics, crawl spaces, and a video scan of the flue.
Do gas and oil appliance chimneys need annual inspection?
Yes. Masonry chimneys venting boilers, furnaces, and water heaters should be inspected every year to catch liner damage, sizing issues, moisture problems, and draft defects.
Can an inspection tell me if chimney relining is needed?
Yes. An inspection can reveal damaged flue tiles, condensation issues, or an oversized flue that may require relining for safe venting.
Will I receive a written report?
Yes. We provide clear findings and recommendations after the inspection.
Trying to price out relining after an inspection?
If the inspection points to liner damage or sizing issues, review the factors that affect a reline quote before you compare options.
