Ductwork Cleaning, Sealing & Repair — Fort Worth, TX
There's a reason ductwork cleaning, sealing & repair in Fort Worth is mostly handled by small shops, not the big franchises: nobody beats a guy who knows the housing stock and answers his phone. We work clean, leave the area better than we found it, and stick around to test the repair before we drive off.
What you're paying for
Most homes have leaky ducts losing 20-30% of conditioned air to attics and crawl spaces. Sealing the duct system is the highest-ROI HVAC improvement most homeowners can make.
We test ducts with a blower door + duct blaster, identify leaks, and seal them with mastic (better than tape long-term) or aeroseal injection.
Full duct replacement is rare — only on systems with collapsed flex-duct, severe pest damage, or major redesign needs. More common: targeted replacement of damaged sections plus sealing of the rest.
How Fort Worth jobs differ

One we ran last year
A Fort Worth customer in their original to home home had been chasing upstairs always 6-8° hotter than downstairs for weeks before calling. Crushed flex duct in attic and 30% leakage was the actual cause. We replaced damaged section, sealed remaining ducts, added zone damper, temperature differential dropped to 1-2°; everything stable since. About $1674 all in.
