Subdivisions in Southlands, Saddle Rock, Tallyn's Reach and the developments east of E-470 are full of homes built in the last 25 years, most with basements. Many were built without an active radon system, so testing after move-in is worth doing.
Older neighborhoods closer to Colfax and in north Aurora include ranch homes and split-levels with crawlspace sections. These often need a crawlspace membrane in addition to a sub-slab system.
Because many Aurora homes have unfinished basements and simple layouts, installation is often straightforward. Finished basements raise the cost because the pipe has to be routed through closets or the garage.

Often, yes. If a newer home has a passive vent pipe from the builder and still tests high, a contractor can usually add a fan to make it an active system for less than a full installation.
Colorado requires radon mitigation professionals to be licensed by the Department of Regulatory Agencies (DORA). Ask for the Colorado license number, look for NRPP or NRSB certification, get a written quote that includes a post-mitigation test, and ask about the fan warranty.
