The cost to install siding in Thornton ranges from $6,210 to $22,750, with most homeowners paying around $12,410. Your actual cost depends on several factors specific to your home and the Denver-Aurora market.
Vinyl is cheapest ($4–$8/sq ft installed), fiber cement is mid-range ($8–$14/sq ft), and wood costs $8–$16/sq ft. Engineered wood offers a good balance.
More exterior wall area means more material and labor. Two-story homes have more wall area than single-story homes of the same footprint.
Removing existing siding adds $1–$3/sq ft. Some contractors install over existing siding if it's in decent condition, saving removal costs.
Adding foam insulation board under new siding ($1–$3/sq ft) improves energy efficiency and can pay for itself in energy savings.
Window trim, corner boards, soffit, and fascia work adds 20–30% to the siding project cost but is essential for a finished, weathertight result.
Mountain region costs are rising with population growth. High altitude and variable weather can affect project timelines. Skilled trade labor is in high demand in booming markets.
Budget $52–$315 for permits and inspections. Your contractor typically handles the permit process, but confirm this upfront.
Dry conditions are ideal for most construction year-round. Hard, rocky ground can increase excavation costs for projects requiring trenching or foundation work.
While possible for experienced homeowners, siding installation involves significant complexity. In Thornton, you may still need a licensed pro for permits and inspections. DIY could save $4,781–$6,147 in labor.

Vinyl siding offers the lowest installed cost ($4–$8/sq ft) and requires virtually no maintenance. Fiber cement (like James Hardie) costs more ($8–$14/sq ft) but lasts 50+ years and holds paint better. For long-term value, fiber cement is often the best investment.
Sometimes — vinyl and some other sidings can be installed over existing siding if it's flat and in reasonable condition. However, this hides potential issues like rot or moisture damage. A full tear-off and house wrap installation is recommended for the best long-term results.
