Frequently Asked Questions
What areas does PrimeStone Construction Group serve?
PrimeStone serves the greater Denver metro (Denver, Aurora, Lakewood, Westminster, Thornton, Broomfield, Greenwood Village, Cherry Hills Village, Castle Rock), the foothills (Golden, Boulder), and Colorado mountain communities (Breckenridge, Silverthorne, Vail, Avon, Aspen). Select your city on this page for local details.
Do you charge more for projects outside Denver?
Costs vary by location based on real factors — mountain communities and foothills carry higher costs due to snow-load engineering, wildfire requirements, and logistics, while some suburbs are more affordable. We provide location-specific estimates that reflect the true cost of building in your area, not flat markups.
Do you serve mountain communities like Vail and Aspen?
Yes. We build custom homes and undertake comprehensive luxury renovations in Breckenridge, Silverthorne, Vail, Avon, and Aspen, engineered for high altitude, snow loads, wildfire resilience, and each town’s specific permitting — including Design Review Boards and FAR limits.
Which services are available in my city?
It depends on your market. Suburban cities have the full range (basements, kitchens, additions, ADUs, custom homes), while mountain communities focus on custom homes and full renovations, where basement and ADU work is less relevant. Your city page lists the services we offer locally.
