Ductwork Repair, Sealing & Replacement in Sacramento
One room that's always hot? Weak airflow? Utility bills that keep climbing? Nine times out of ten it's the ducts, not the AC. Leaky ductwork in an attic can waste 20–30% of the air you're paying to cool.

Our process
Our ductwork process
Step 01
Inspection and static pressure test
We crawl the ducts, measure static pressure, and identify leaks, restrictions, and undersized runs.
Step 02
Written diagnosis
You get a plain-language explanation of what's wrong and what fixing it will actually change.
Step 03
Seal, repair, or replace
Sometimes it's mastic and mechanical fasteners on a few joints. Sometimes it's a redesign. We recommend the smallest fix that actually solves the problem.
Step 04
Balancing
After sealing, we re-balance the vents so every room gets what it needs.
Step 05
Verification
We re-measure airflow and temperature at each vent so you can see the difference.

How much does it cost to seal or replace ductwork?
+
Sealing runs $500–$1,800 depending on access and how many joints leak. Full replacement of an attic duct system is $3,500–$9,000 in most Sacramento homes.
Will sealing my ducts really lower my bill?
+
In most Sacramento homes with attic ductwork, yes — often 15–25% off cooling costs. The exact number depends on how leaky your ducts started out.
Can you fix one hot room?
+
Usually yes — most of the time it's an undersized or crushed run, a leak at a joint, or an unbalanced damper. We diagnose, then fix the actual cause.
Do you replace flex duct with hard pipe?
+
When it makes sense — long trunk runs and short branch takeoffs is the right design in most homes. We'll tell you when it's worth the extra cost.
Is duct cleaning the same thing?
+
No. Cleaning removes dust; sealing fixes leaks. They solve different problems. We'll tell you which one you actually need.
