Mold Remediation in Colorado Springs

Updated November 12, 2026

Mold remediation in Colorado Springs almost always traces back to water that got trapped where the dry air could not reach it. People are often surprised to find mold in a climate this arid, but the pattern is very consistent: a slow leak behind a finished basement wall, a dishwasher drip under laminate flooring, or a roof leak that soaked attic insulation after a hailstorm. The surface dries, the room looks fine, and growth spreads quietly in the cavity. This page covers where mold hides in local homes, testing vs remediation, and how the work is done.

Where mold hides in local homes

Finished basements

Basements here often have carpet over a concrete slab and drywall framed against foundation walls. When water comes in through a window well, a slab crack or a sump failure, the back of the drywall, the bottom plate and the carpet pad can stay damp long after the carpet surface dries. See basement and window well flooding for the water side of that problem.

Under flooring

Vinyl plank, laminate and sheet vinyl are nearly waterproof on top, which means water underneath has nowhere to go. A slow leak from a dishwasher, fridge line or toilet can feed mold on the subfloor for months.

Attics

Hail damaged roofs, ice dams and swamp cooler leaks soak insulation and the roof deck. Attics are dark and rarely checked, so growth on the underside of the roof sheathing often goes unnoticed. Our page on hail and roof leak water damage explains how those leaks start.

Inside walls and behind cabinets

Supply lines to sinks and toilets, plus drain lines and ice maker lines, can drip into a wall or cabinet base for a long time before a stain shows.

Crawlspaces

Older homes with crawlspaces, common in the historic west side and central neighborhoods, sometimes have bare dirt floors with no vapor barrier. Moisture rising from the soil, a slow plumbing drip or storm runoff that slips under the foundation keeps floor joists damp. Growth on joists and the underside of the subfloor is common down there, and a musty smell in the rooms above is often the first clue.

Bathrooms with weak ventilation

Exhaust fans that vent into the attic instead of outside, or that do not run long enough, can push moisture into ceiling insulation.

Testing vs remediation

These are different services, and many in the industry recommend that they be done by separate companies to avoid a conflict of interest.

• Testing uses air samples, surface swabs or tape lifts analyzed by a lab. It tells you what kind of mold is present and in what concentration. It does not remove anything.
• Remediation is the removal and cleaning of mold and the materials it has damaged. It also involves fixing the moisture source.

If you can see the growth and know the cause, you may not need testing at all. Our article on mold after water damage in a dry climate goes into when testing makes sense.

What to do right now

1. Do not disturb it. Scraping, sanding or dry brushing mold releases spores into the air.
2. Do not run fans pointed at moldy areas. That spreads spores through the house.
3. Find and stop the water source if you can, such as shutting off a leaking supply line.
4. Keep the area closed off with the door shut if possible.
5. If you or anyone in the house has breathing problems, limit time in that area and talk to your doctor.
6. Take photos of visible growth and any staining for your records.

How remediation is done

Inspection and moisture source

The tech looks for visible growth, follows odors, and uses moisture meters and a thermal camera to find where water is still present. Fixing the source is the first priority, since remediation without it is temporary.

Containment

The work area is sealed with plastic sheeting, often with a zippered entry. A negative air machine with a HEPA filter exhausts air from the space so spores do not escape into the rest of the house. HVAC vents in the area are sealed, and the crew may ask you to keep the furnace or air conditioner off and pets out of that part of the house during removal.

Removal

Porous materials with growth, such as drywall, insulation and carpet pad, are cut out and bagged inside the containment. Removal usually extends beyond the visible growth to catch what is hiding at the edges.

Cleaning

Framing, subfloor and other structural materials that can stay are cleaned with HEPA vacuums and wiped down. Sometimes light sanding or other cleaning methods are used on wood that is stained.

Drying and final check

The area is dried to normal moisture levels. Air scrubbers run until the end of the job. Some homeowners arrange independent clearance testing at this point, before new drywall goes up.

Rebuild

New insulation, drywall, paint and flooring are installed. If the mold came from a recurring source, like a window well or a bathroom fan, the fix should be finished first.

What drives the cost

The company that inspects gives you a written scope and price before starting. Here are the main factors.

How long it takes

A small, contained job, like one wall section or a bathroom ceiling, often takes one to three days. A larger basement or attic job can take several days to a week before rebuilding starts. If drying is needed after removal, plan on 3 to 5 days more. Independent testing adds time for lab results.

Insurance and mold

Many homeowners policies cover mold only when it results from a covered water loss, like a sudden pipe burst, and many cap mold coverage at a limit lower than the main policy. Mold from long term leaks, high humidity or poor maintenance is commonly excluded. If you had a covered water event and mold followed, tell your insurer right away. If you rent, our article on landlord and tenant water damage in Colorado explains who usually handles what.

When to call

Call if you see mold larger than a few square feet, if you smell mustiness in a basement or closet, if a stain keeps coming back after painting, or if you had water damage that was not professionally dried. A home inspection that flagged possible mold before a sale is another good reason to get a closer look. Call soon after any leak that soaked carpet, drywall or insulation, since growth can start within a couple of days. Crews cover the whole region, including Woodland Park and Palmer Lake.
