Do I need a permit for ductwork replacement in Centennial, Colorado?

City permits plus HOA architectural approval. Always confirm current requirements with the local building department before signing a contract, and make sure the permit is pulled by your licensed contractor.

How much does ductwork replacement cost in 2026?

Most homeowners pay between $3,750 and $9,000, with a national average near $6,375. Small, simple jobs land at the low end; large or premium-material jobs run well above the high end.

What is the cost per linear foot?

Installed pricing usually runs $25.00 to $60.00 per linear foot, including labor and materials. Expensive metros can run 15–45% higher than that range.

What drives the price up the most?

Scope and access. Larger quantities lower your per-linear foot price, but difficult access, demolition of existing work, structural repairs found mid-job, premium materials and rush scheduling each add 8–30%.

Permits are typically required when the work changes structure or ties into electrical, plumbing, gas or mechanical systems. Budget $75–$600 in most cities and confirm whether your contractor pulls it — unpermitted work can block a future home sale.

How long does the job take?

Most residential projects of this type finish in one to five working days once materials are on site. Custom orders, inspections and weather are the usual causes of delay.

How many quotes should I get?

Three. Bids on the same scope commonly vary 20–40%, and the middle bid with the strongest warranty and references is usually the best value — the cheapest bid often excludes prep, disposal or permits.
