We clean storm windows for year-round protection
Storm Window Cleaning in Knoxville, TN
Storm windows protect your primary windows and your energy bill — but the space between the two is a magnet for dust, dead insects, and condensation grime that regular cleaning never reaches. Over time that buildup clouds the view and traps moisture against your good windows.
Underwood cleans storm windows the right way: we clean the storm panels, the primary glass, and the often-forgotten cavity in between, then make sure the weep system is clear so moisture can escape.
What’s Included
- Storm window panels cleaned inside and out
- The primary window behind cleaned as well
- The cavity between storm and primary glass cleared of debris
- Weep holes checked and cleared so moisture drains
- Frames, tracks, and sills wiped down
Why It Matters
Storm windows only do their job — cutting drafts and shielding your primary windows — when they're clean and draining properly. Debris in the cavity and clogged weep holes trap moisture, which fogs the glass and, over time, can damage frames and sills.
Cleaning them restores clarity you probably forgot you'd lost, and protects the more expensive primary windows sitting right behind them.
