Duct Sealing & Repair Nanticoke, ON
Duct sealing and repair starts by locating leakage and distinguishing it from damaged or undersized runs. For a Nanticoke property, ask whether the proposed assessment includes pressure testing and whether the readings will be recorded before and after work. Note accessible return ducts, joints, boots, and any crushed or corroded sections. Photos and a system diagram help show where air may be drawn from adjacent spaces. Mastic, replacement material, and access needs should be specified for each repair.
Are return ducts drawing air from adjoining spaces?
Ask how leakage will be tested and whether both return and supply sections will be inspected. Recorded pressure-test findings can help identify which joints or damaged runs are included in a repair proposal.
Request Test Findings Before and After
Ask what pressure-testing method will be used, which parts of the system will be included, and whether readings will be documented before and after sealing. Testing can help prioritize leaks rather than treating every joint as equally important. Access, system configuration, and test conditions affect interpretation, so request an explanation of what the results do and do not measure.
Check Return-Side Leakage Separately
If a return duct has gaps near a basement, crawlspace, or other adjoining area, ask whether those connections will be inspected and included. Leaks on the return side can draw air from outside the intended living-space path. Photographs of joints and boots help define the work. Confirm whether mastic sealing is proposed and what surfaces or locations are excluded.
Specify Repairs to Damaged Metal or Runs
If a section is crushed, rusted, loose, or separated, ask whether repair means replacing material or sealing a joint. Photograph the affected area and note whether it is accessible. The material, fastening, and mastic-sealing details influence the scope; tape alone should not be assumed to repair a structurally damaged section. Confirm the proposed repair in writing before work begins.
