La Verkin (ZIP 84745) sits next to Hurricane and the Sand Hollow corridor, and it includes homes of many ages. For older homes the main ducts problem is not design but time. Tape applied years ago has been through hundreds of heat cycles, and attic air can reach 120°F or higher on a sunny summer day.

Duct sealing La Verkin Utah residents ask about typically begins with a pattern: summer bills that creep up, a room that has gotten harder to cool, or dust that seems to be increasing. A duct leakage test measures whether leakage has grown.

Why older ducts leak more

Cloth tape fails. It heats up, cools down and lets go, often leaving a seam open.
Seams move. Metal expands and contracts every day, and unsealed seams work loose over time.
Flex duct sags. Connections can be pulled or compressed during other work in the attic.
Mastic is rarely original. Older systems were often sealed with tape, not mastic.

The upside is that retrofit sealing often has a large payoff, because the system started from a high leakage number. A test tells you how high.

What a retrofit job involves

We test the system, inspect the accessible runs, remove failed tape where needed, and seal joints with mastic and UL 181B-FX foil tape. Where leaks are out of reach we may use aerosol sealing, and sections that are crushed or disconnected need repair first. Then we test again and give you both numbers.

A typical sealing job runs 2 to 8 hours, and about 4 hours for most homes, according to Angi. See our duct sealing cost guide for published ranges.

Because older systems vary so much, we never quote from a distance. The first test shows the baseline, the inspection shows where the air escapes, and only then do we recommend what to seal, what to repair and what to leave alone. That sequence is the same in every home we visit.

Sealing versus replacing in an older home

In an older house, the question often comes up: seal the ducts or replace them? If the ducts are intact, sealing is usually the lower-cost fix. If sections are crushed, torn or in poor shape throughout, replacement may be worth discussing. The test and inspection tell us which.

Our comparison of sealing versus replacing ducts explains how to decide, and is duct sealing worth it shows how to weigh the savings.
