Professional Mold Removal - Done the Right Way, Step by Step
Each stage is performed by the independent remediation contractor the call reaches, following industry standards.
-
Step 1: Assessment
An assessor identifies the presence of mold, determines how far the growth extends, and locates the source of moisture.
-
Step 2: Containment
Protective barriers and negative air pressure are established to prevent spores from spreading into unaffected areas.
-
Step 3: Removal
Porous materials that cannot be safely cleaned are removed — including drywall past the moisture line, insulation, carpet pad, and damaged cabinet bases.
-
Step 4: Drying
Commercial dehumidifiers and air movers return the structure to a dry standard, with moisture readings taken from the material itself rather than the surface.
What drives moisture problems in Longmont
The Longmont area independent local pros cover for mold removal takes in Downtown, East Side, and West Side. 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. An ordinary May is the irrigation laterals out on the plains, leaking into basements on ground a rain gauge would call dry.
Common moisture and mold problems in Longmont
- St. Vrain floodplain blocks where May snowmelt and a Front Range cell arrive together
- 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.
The creek is nowhere near us and the basement is damp all summer. Why?
The ditches. A grid of irrigation laterals crosses these plains blocks and leaks all season, so a 1990s basement stays damp through months that barely register on a rain gauge. It runs on the irrigation calendar rather than the weather.
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.
