Radon Mitigation in Baltimore, MD
Baltimore MD radon work is needed because most of MD falls in EPA Zone 1 — highest potential. Slab-on-grade and basement homes both test elevated regularly. NRPP or NRSB certifications are standard for quality installers. Baltimore permits required. Quiet exterior fan installations are the local default — basement-fan installs draw complaints.
Baltimore radon mitigation systems run $1,500-$3,500 for slab-on-grade, $2,500-$5,500 for basement. MD requires a state contractor license. NRPP/NRSB certification recommended.
