Radon mitigation quotes in Lakewood
Lakewood spreads west of Denver toward the foothills, a large city built substantially in the postwar decades with ranch and split-level neighborhoods plus newer development along its corridors.
Postwar Front Range housing tests elevated regularly. Lakewood homeowners hire independent, nationally certified contractors.
Lakewood and Jefferson County
Lakewood routes through our Denver-Jefferson territory alongside Denver, Wheat Ridge, Golden, and Morrison. EPA places Jefferson County in Zone 1 on its Map of Radon Zones. Colorado does not license radon professionals; look for NRPP or NRSB national certification.
If the result surfaced in a transaction
Family moves and metro relocations drive a steady market. Colorado requires sellers to provide a radon warning statement and the state brochure before a sale; nothing requires testing or mitigation, and the remedy is negotiated between the parties.
Those duties are set in Colorado, not in Jefferson County — Colorado radon disclosure rules has the statute and the agency behind it, including what a seller must hand over and what stays negotiable.
The housing you’re mitigating
Expect postwar ranches and split-levels on block or poured foundations, most with full basements and some with crawl areas beneath additions. Foothills-adjacent lots produce walkout and multi-level configurations. Split-levels deserve zone-by-zone quotes naming every foundation section.
Radon results do not stop at a municipal boundary, and neither do the contractors quoting here: the same Jefferson County soil and the same building era run through Denver, Arvada and Littleton, which is why a reading in one of them is worth knowing about when you are interpreting yours. For the wider picture, radon across Denver Metro sets out how results vary between communities here, and what a system costs in Denver Metro covers the price drivers before you start collecting numbers.

Lakewood questions, answered straight
What changes about mitigation in a split-level house?
By treating the house as its zones — basement slab, any slab-on-grade section, and any crawl area, commonly all on one fan. Watch for a quote that skips a zone.
Our basement is a walkout. Does radon still apply?
Yes. A walkout still has a slab in soil contact and at least one below-grade wall, and radon enters through the same cracks, joints, and penetrations. Grade exposure on one side does not clear the slab.
How much does mitigation cost in the Denver metro?
Straightforward basement installs are commonly quoted in the low four figures, with multi-zone foundations, finished-basement routing, and larger slabs quoting higher. We publish a full cost breakdown rather than promising your number.
What documentation should we keep once the system is in?
The installer's NRPP or NRSB certification as it appears on the contract, the scope or diagram showing suction-point locations, the post-mitigation test report with its date, and the fan model with warranty terms. Colorado does not license radon professionals at the state level, so that national credential is the verification available to you — and in a Lakewood sale, the folder turns the required radon warning statement into a settled item.
How long does a radon fan last?
Fans run continuously, carry manufacturer warranties measured in years, and are treated as wear items after that rather than permanent equipment. A replacement drops onto the same riser, so mounting location matters — garage, attic, or exterior, never a finished room, both for safety and for the day it needs changing. Before signing in Lakewood, ask who administers a warranty claim and whether the labour to change the fan is included or billed as a separate visit.
