Duct Sealing & Repair London, ON
Persistent dust, uneven airflow, or visible damage around accessible ducts can justify an inspection, but those symptoms alone do not identify a leak. Ask whether the system will be checked before sealing and whether findings will distinguish supply-side from return-side leakage. A return leak may draw air from a surrounding cavity, while crushed, detached, or punctured runs may need repair rather than sealant. Photographs and a written scope help show why each proposed repair is included.
Does dust keep returning soon after cleaning?
Photograph accessible loose joints, damaged duct, or dusty areas near returns. Ask how leaks will be identified before work and whether the proposal distinguishes sealing joints from repairing crushed or detached runs.
Inspect before deciding what to seal
Ask how accessible ducts will be examined and whether pressure checking is proposed. Request photographs or marked findings for joints, holes, or detached boots identified as leaks. Testing and access influence the scope; sealing without locating the problem can leave the suspected source untouched.
Distinguish return leaks from supply leaks
Ask whether findings are on the return or supply side. A return leak may draw air from a floor or wall cavity into the system, while a supply leak sends conditioned air elsewhere. The location changes the likely effect and repair priority, so request clear notes rather than a general promise to seal ducts.
Match repairs to the damage
If renovation or other work may have crushed flex duct, detached a boot, or punctured a run, photograph the location and describe what is accessible. Ask whether the damaged section needs reattachment, rebuilding, or replacement rather than surface sealing. Materials, access, and the extent of damage determine a practical repair scope.
