What a licensed remediation job actually involves, in the order it happens. Every step below is the contractor's work, not ours.
-
Step 1: Assessment
A licensed assessor establishes whether there is growth, how far it extends, and where the moisture is coming from.
-
Step 2: Containment
Barriers and negative air pressure go up first, so disturbing material does not move spores into clean rooms.
-
Step 3: Removal
Porous material that cannot be cleaned comes out - drywall cut past the moisture line, insulation, carpet pad, cabinet bases.
-
Step 4: Drying
Dehumidifiers and air movers bring the structure back to a dry standard, with readings logged from the material rather than the surface.
What drives moisture problems in Longmont
The Longmont area our local pros cover for mold removal takes in Mead, Frederick, and Firestone. The St. Vrain left its 2013 marks through downtown, and the rest of the city is Front Range irrigation laterals on the plains, so May's 2.53 inches is small until it is a creek in the street or a ditch against a basement.
Housing stock
Building in Longmont clusters in the early 1990s: the median unit dates to 1991, with 47.7 percent finished before 1990. Post-1970 frame on basements, median 1991, from the St. Vrain floodplain out onto irrigated plains lots, with just under half predating 1990.
Climate and water risk
Of the 16.08 inches that arrive in an average year, 2.53 fall in May; the 1991–2020 normals come from a gauge 1.2 miles away at LONGMONT 1.8 E. May's 2.53 inches of a 16.08 inch year is a spring peak that looks harmless until the St. Vrain is carrying the mountains. 2013 was the creek in downtown. Ordinary May is laterals on the plains leaking into basements a Front Range gauge calls dry. Boulder can have the canyon flash. This town has the creek and the ditch.
Common moisture and mold problems in Longmont

- Irrigation laterals on the plains leaking into 1990s basements all summer
- 2013-flood silt still in the lowest downtown joints
- Hail-stripped roofs taking the next May rain through bruised covering

Frequently asked questions
2013 was St. Vrain. Does a house off the creek still take that kind of water?
Not that kind. Off the creek, May is laterals and hail, not a mountain flood. 2013 is the downtown story and it is real. Copying it onto a plains lot a mile from the channel misses the ditch that actually wets that basement. The creek is a corridor. The laterals are a grid.
Boulder is next up the creek. Same Front Range moisture job?
Boulder sits against the foothills and takes canyon flash. Longmont sits on the plains where the St. Vrain has already left the canyon, plus a grid of irrigation ditches. 2013 hit both. Ordinary years do not. Their job is a mountain wall. This one is a plains creek and a ditch. Leave the Flatirons story in the foothills.
Sixteen inches a year. Why is a basement wet in July when May is the peak?
May is the rain peak. July is the irrigation peak. Laterals run when the gauge is quiet, and they leak into the same basements. A sump that runs in July on a dry week is the ditch, not a missed May storm. The 16-inch climate is the brochure. The lateral is the load.
