We Provide Effective Solutions for Drainage Problems

Water in ducts is the most common complaint we receive from homeowners. So how do you know when water has entered your ductwork? If you’re experiencing any of these signs, you most likely have a drainage problem:

  • There are higher humidity levels in your home and you see moisture on your windows

  • There is a gurgling sound or the sound of rushing water when you turn your system on

  • You notice decreased air flow in your home – rooms that usually heat or cool quickly take much longer to do just that

  • You note a musty smell in your home

Understanding how water has entered your ducts and the remedies available is crucial to correcting the issue and preventing further damage.

How Water Entered Your Air Ducts

When a home is excavated, a hole is dug in virgin, hard-packed soil to accommodate for the foundation walls and footings. This hole is larger than the footprint of the foundation, thus, creating a pan or saucer. Once the concrete is poured and the foundation is set, the area around the foundation is filled with loosely-packed fill dirt. This loose fill dirt is not as compact as the undisturbed soil around the foundation, so it creates a less resistant path for water to travel.

Water dropping within five feet of the foundation walls makes its way through the loose fill dirt, under the footing and foundation wall. This increases the normal water table found under the home.

Due to hydrostatic pressure, the water begins to rise and finds its way into your ductwork through joints and seams of your pipes and plenum, which are not designed to withstand that amount of pressure.

Factors that contribute to water in your air ducts

  • Clogged gutters or no gutters on the house

  • Heavy rain

  • Downspouts dropping too close to the house

  • Incorrect pitch of the ground (toward the house)

  • Melting snow

  • Naturally high water table
