Duct Repair & Sealing in Aurora, CO
Leaky, crushed, or disconnected ducts waste the air you paid to heat and cool. We find the losses and seal them properly. Assessment with upfront pricing.
Diagnostic visit · quoted up front · credited toward repair
Your ducts are leaking. The question is how much.
What's included in duct service:
- Full duct inspection — attic, crawlspace, and basement runs checked.
- Leakage & airflow testing — measured losses, not guesses.
- Sealing with mastic — real sealant, not the stuff called duct tape.
- Insulation repair — crushed or missing insulation restored.
- Before/after verification — airflow measured again to prove the fix.
Your ducts may be the problem if…
One bedroom roasts while another freezes — classic sign of crushed or disconnected runs.
Attic or crawlspace leaks pull dirty air straight into your supply. New filter, same dust? Suspect the ducts.
Weak airflow at the vents plus rising bills means heated air is escaping before it reaches you.
Whistling or rumbling from the ductwork often means undersized or collapsing sections.

From your call to fixed
Book
Call (303) 568-5036 or request online. Describe the symptom in your own words — "it won't turn on" is a complete work order.
Diagnose
A technician inspects the system, finds the actual failed part, and explains it in plain English. You see what we see.
Approve
Written price — part, labor, total — before any work begins. You approve, decline, or ask about options. No pressure either way.
Fixed
Most repairs finish the same visit. The system is test-run, safeties verified, and the work area left clean.
Guarantees, not slogans
No-pressure promise
If you decline a recommended repair, that's the end of it. You'll never get a follow-up sales call, a "limited-time" scare tactic, or a tech who won't leave without a signature.
Written prices first
Every price we quote is written down — part, labor, total — before we touch a wrench. If the number changes mid-job, the work stops until you re-approve.
We show our work
Failed parts go in your hand, not our truck. We'll photograph what we found and walk you through it, so you're buying a diagnosis — not a story.
Duct Repair & Sealing — straight answers
How much does duct sealing cost?
Quoted up front depending on accessibility, linear footage, and whether sections need repair or replacement. The assessment (quoted up front) tells us exactly what your home needs — most need sealing, not replacement.
How do I know if my ducts are leaking?
Hot/cold rooms, endless dust, high bills with weak airflow, and musty smells are the classic signs. We verify with inspection and pressure testing — no guessing.
Is duct cleaning worth it?
Sometimes — after renovations, with heavy pet dander, or visible buildup. But sealing usually delivers far more. We'll tell you honestly which one your home needs, even if the answer is "neither."
Can you clean ducts with negative pressure?
Yes — negative-pressure cleaning with compressed-air agitation, fully contained. It's the method that actually removes debris instead of relocating it.
