Air Duct Repair & Sealing for Van Nuys Homeowners

The room that never keeps up is rarely a thermostat problem. In Lake Balboa border and Sherman Way corridor it is usually a duct problem — a crushed elbow, a run that was too long from day one, or a boot that separated from the ceiling and has been feeding the attic ever since. Van Nuys is one of the older and denser parts of the valley, with long stretches of post-war tract housing and a heavy concentration of apartment buildings along Sepulveda and Sherman Way. Industrial and airport activity to the north puts a coarser dust load into the air than the residential streets further south ever see.

What we run into in Van Nuys is shaped by original tract-home ductwork that has never been opened, plus shared apartment risers carrying air between units. So the work starts with a diagnostic rather than a guess — we walk the accessible runs, check static pressure and airflow at the registers, and find where the loss actually is instead of sealing whatever is easy to reach. Repairs get made with mastic and fiberglass mesh, never tape, which fails fast in an attic this hot.

What We See in Van Nuys Neighborhoods

Air Duct Repair & Sealing in Van Nuys — FAQ

A duct leak inspection and airflow diagnostic in Van Nuys is $189 and gets credited toward the repair. Reattaching a disconnected boot runs $149 per connection, and plenum sealing — usually the biggest leak in the house — is $299. Call (951) 555-0170 for an exact quote.

The usual signs are one or two rooms that never keep up, cooling bills well above similar homes, a whistling or rushing sound in the ductwork, and dusty, attic-smelling air out of the registers. A pressure test confirms it and shows where the loss is.

In a typical home a meaningful share of conditioned air is lost through duct leaks before it ever reaches a room. Sealing the plenum, trunk joints, and register boots is one of the cheaper efficiency fixes available, and it usually improves comfort in the problem rooms at the same time.

Mastic with fiberglass mesh on every joint we can reach. Standard duct tape dries out and lets go, and in a Van Nuys attic that runs well past 140°F in summer it fails faster than most homeowners expect. Mastic stays put.
