Duct Sealing & Repair Dunnville, ON
If dust seems to enter through ductwork near a basement, crawlspace or workshop, inspect accessible joints and note any crushed or disconnected sections. A pressure test can help locate leakage, while sealing may involve mastic at joints and boots or repair of damaged runs. Photograph the affected areas and ask whether the test covers supply and return sides. Duct material, access and the location of a leak change the repair scope and the method used.
Could a duct leak be drawing in unwanted air?
Photograph accessible joints, boots and damaged runs. Ask whether testing distinguishes supply and return leakage, and how results will guide the proposed sealing or repair.
Use measurements to guide sealing
Ask whether a manometer or other pressure measurement will be used, which parts of the system will be tested and how results will be documented. Testing can help direct work toward identified leakage rather than guesswork. Comparing measurements before and after may show a change, but the reading should be explained with the test conditions and scope.
Inspect return-side connections
If return ducts pass through a basement, crawlspace or shop, photograph accessible joints and note nearby dust or debris. Ask whether the return side will be checked separately from the supply side. Leakage location matters because a return opening can draw surrounding air into the system, while the appropriate repair depends on access and the duct’s condition.
Document damaged or disconnected runs
Look for visibly flattened flexible duct, loose boots, separated joints or corrosion, and take photos without disturbing the material. Ask whether the proposed work includes reconnecting or replacing damaged sections as well as sealing joints with mastic and fasteners. The type and extent of damage affect whether sealing alone is suitable and how much access the repair requires.
