What exterior painting covers

Exterior painting in the Denver metro typically includes washing and prep, scraping failed coatings, priming bare substrates, caulking, and applying body and trim finish coats. Substrates may include wood siding and trim, previously coated masonry or stucco, and metal doors or frames. Commercial elevations often need lift access and tighter overspray control. A municipally licensed Denver general contractor coordinates the finish package and licensed specialty trades when carpentry repairs or other regulated work is discovered during prep. Cost is project-specific and depends on elevation count, prep condition, product system, and access.

text

Front Range weather and prep

Intense sun, freeze-thaw cycles, hail, and wind-driven rain punish weak scraping, priming, and caulking. Bare wood, chalking paint, and open joints should be corrected before finish coats. Weather windows matter: coatings need appropriate temperature and dry time for the product data sheet.

text

Permits, landmarks, and HOAs

Cosmetic exterior painting that does not change structure is generally treated as finish work that does not need a City and County of Denver building permit through Community Planning and Development. Confirm when painting is bundled with permitted siding or repair work. Denver Landmark Preservation reviews exterior changes on designated landmarks and historic-district properties when a building or zoning permit is required. Ask Landmark staff before exterior color changes on designated properties. HOA color approval is separate. Cities and counties license general contractors. Colorado has no statewide general contractor license.

Pre-1978 exteriors

Paid work that disturbs paint on pre-1978 housing or child-occupied facilities can trigger the EPA Renovation, Repair and Painting Rule even when no building permit is required. Buyers should ask how firm certification, renovator oversight, containment, and Renovate Right acknowledgments will be handled when the building is pre-1978.

FAQ

Common questions

How much does Exterior Caulk Refresh - Windows and Doors cost in Thornton?

$395.

How do I book?

Press Book next to the job, pick a date and a morning (8–12) or afternoon (12–4) window, and pay in full. We confirm within 24 hours or refund you in full.

Do I need a Denver building permit to repaint the exterior?

Usually no for cosmetic-only exterior painting. CPD is the building-permit authority inside Denver. Confirm if the paint work is part of a larger permitted repair or siding project.

Who handles exterior painting permits and licensing?

A municipally licensed Denver general contractor coordinates the project and the licensed specialty trades required when other regulated work is included. Colorado has no statewide general contractor license.

Do historic districts or HOAs control exterior colors?

They can. Landmark Preservation may be involved for designated landmarks and historic-district properties, and many HOAs require color approval before work starts.

What should an exterior painting proposal include?

Elevations in scope, prep level, coat count, product approach, protection for landscaping and adjacent surfaces, weather contingencies, and exclusions such as rot or stucco repair.

What changes for homes built before 1978?

Disturbing painted surfaces can trigger EPA RRP requirements. Ask how lead-safe practices and documentation will be handled for that address.
