Duct Leak Detection & Airflow Balancing Specialists
Sealing the Leaks Your System Never Told You About

Ductwork Repair in Florissant, MOBacked by an Actual Static Pressure Test

A surprising share of a home's conditioned air never reaches the vents at all — it escapes through leaky duct joints in the attic or crawlspace.

Insulation and airflow balancing are addressed together, not treated as separate problems.

Leaky or poorly balanced ductwork can waste a significant share of a system's output before it ever reaches a single vent, and most homeowners never know to check, which is exactly why ductwork repair calls in Florissant, MO get treated with urgency, not a next-available-Tuesday slot.

Duct Leakage Testing, Not Guesswork

We use pressure testing equipment to quantify actual duct leakage rather than sealing wherever looks suspicious.

Mastic Sealing, Built to Last

We adjust dampers and measure room-by-room airflow after sealing, not just at the trunk line.

Before You Call: Ductwork Repair Answers

How do I know if my ductwork actually has leaks?+

Signs include uneven room temperatures, unusually high utility bills, and visible gaps at duct joints in an attic or crawlspace.

Is duct tape an acceptable long-term fix for duct leaks?+

No — despite the name, standard duct tape degrades quickly in attic heat and typically fails within a few years.

Can leaky ductwork really affect my utility bills that much?+

Yes — conditioned air lost through duct leaks before reaching the vents is effectively paid-for air that never does its job.

What's the difference between a duct leak and an airflow balancing problem?+

A leak physically loses air before it reaches the vent; a balancing problem means air reaches the vents but unevenly across rooms.

Do you inspect ductwork in attics and crawlspaces, or just what's visible?+

We access attic and crawlspace duct runs directly rather than relying only on what's visible from inside the home.

How quickly can someone inspect my ductwork in Florissant?+
