Duct Sealing Service in Sioux Falls, SD
Duct sealing closes the gaps, loose connections, and failed tape joints that allow conditioned air to dump into attics, crawlspaces, and wall cavities instead of reaching living areas. Most homes with duct systems older than fifteen years have meaningful leakage. You feel it as rooms that never get comfortable, a furnace that runs constantly, or utility bills that don't match the size of your home. Sealing puts that lost air back where you paid to condition it.

When to Call
When You Need Duct Sealing Service
- Your second floor stays warm in summer no matter how low you set the thermostat

How It Works
Our Process for Duct Sealing Service
- 1
Leakage Assessment
We inspect the full duct system to locate joints, seams, and connections that are failing.
- 2
Mastic Application
We apply mastic sealant to leaking joints — it outlasts any tape and bonds to metal and flex duct.
- 3
Connection Reinforcement
Loose flex duct connections are re-secured and strapped before sealant is applied over the joint.
- 4
Airflow Spot-Check
After sealing, we verify that previously weak registers are now delivering noticeably better airflow.
Sioux Falls Context
Why this matters in Sioux Falls
Many Sioux Falls homes built in the 1980s and 1990s have duct systems sealed with cloth tape that has dried out and pulled away from joints. That tape was never a long-term solution, and by now most of it has failed.
Straight Talk
About pricing & scope
The number of leaking connections and how accessible the ductwork is both affect the time and scope of this work. Attic ductwork in July and crawlspace ductwork in February take longer — that's just reality.
