This section covers the parts of radon mitigation that are easy to get wrong from a search result alone: what actually happens during an installation, why a passive rough-in and a full active retrofit are different jobs with different scopes, and how a 1920s Denver bungalow gets treated differently than a Golden crawlspace or a Westminster split-level. Some posts go deep on a single technical question — fan sizing, manometer placement, why an exterior run sometimes needs a custom-printed transition piece. Others are written for a specific city, because radon mitigation is genuinely local: the soil, the foundation styles, and even the routing options change from one part of the metro to the next. The aim throughout is practical: the questions that come up on real jobs are the ones that get written up.

If you're early in the research process, two posts are a good place to start. The cost guide for Denver-area homeowners breaks down the factors that move a quote up or down — foundation type, crawlspace access, how far the exterior run has to travel — instead of pretending every house fits one number. The complete guide to how these systems work covers the technical side end to end: suction points, fan selection, and why two systems that look identical from the driveway can be doing very different jobs underground.

Several posts are organized by city, matched to the neighborhoods and housing stock Martens Radon sees most often. If your city has its own page, it's usually the fastest way to find what applies to your specific house: Denver, Arvada, Westminster, Lakewood, and Golden each cover the foundation types, typical pricing bands, and the questions that come up most in that part of the metro. Wherever you start, the aim is the same — enough detail that you know what to ask before anyone sets foot in your basement, and enough context that a quote makes sense instead of feeling like a number pulled out of thin air.
