Frequently Asked Questions

These are the questions homeowners in Arvada and the west Denver metro ask most often when they call. Each one leads with the answer.

Denver is semi-arid. How does my basement grow mold?

Because the water came from the ground or the roof, not the sky. Expansive clay around the foundation swells with snowmelt and cracks the wall, window wells fill in a storm, and a sump pump that quits leaves the pit to overflow. A finished basement hides all three. Mold removal begins at the wall with a meter to work out which one.

Is the dark growth on my basement drywall black mold?

Color alone does not name the species, and the name would not change the work. Dark, green, gray, or white growth on wet drywall gets the same sequence: find the water, seal the room, remove what is porous, clean what is not. Black mold removal lays out the sequence for a dark patch in a basement laundry.

Can I wipe off a small patch in the basement myself?

A spot smaller than a dinner plate on bare concrete, tile, or a painted block wall, yes, with detergent and water. Drywall, carpet pad, paneling, insulation, a cabinet floor, or attic sheathing, no. Bleach soaks the paper face and misses the growth inside the board, and scrubbing a big patch without containment spreads it upstairs.

The house smells musty when the furnace runs. Why?

Because the blower is pulling air across something wet: a humidifier pad, a damp filter, a return duct that runs through a wet basement wall, or a cabinet that an evaporative cooler dripped into all summer. HVAC mold cleaning covers the furnace, the coil, the humidifier, and the returns.

Our swamp cooler leaked onto the roof. Is that a mold problem up there?

Often, yes. A rooftop evaporative cooler drips onto the decking or down the duct chase, and the pad water keeps that spot damp from May to September. Dark streaks on the sheathing around the chase are attic mold remediation, and the crew looks at the pan, the float, and the curb while they are up there.

The sump pump died during the March melt. How bad is it?

Bad enough to call. Meltwater that should have left through the discharge line sat in the pit and spread under the carpet pad for days before you noticed. Growth across the whole lower level is whole-home mold remediation, planned in zones with the pump replaced first.

Hail opened the roof and the ceiling stained. Is there mold in the attic?

Possibly, and the stain tells the crew where to look. Hail cracks shingles and splits vent boots, and one summer storm can put water on the sheathing and insulation. The crew goes up through the hatch above the stain and meters the sheathing before anything is removed.

A pipe froze and burst in January. The wall is dry now. Am I done?

Not until someone has metered it. A wall that felt dry to the touch in February can still hold wet insulation and a damp bottom plate, and the growth shows up in May. Ask the provider to read the cavity before you close it, and keep the plumber's invoice for your adjuster.

Do I need a lab test before the crew pulls the drywall?

When you can see the growth and you know the water that caused it, usually not. Testing earns its place when growth is hidden, a buyer or a landlord wants numbers, or two parties disagree. Colorado does not license mold assessors, so testing is something you arrange yourself; the providers reached through this site do the removal.

Once the basement wall is closed, will the mold return?

Only if the water does. Every job through this site ties removal to the source: the crack, the window well, the pump, the pipe, or the roof. A basement wall closed over an unsealed crack grows mold again by the next melt.

Does homeowners insurance pay for mold from a wet basement?

Your carrier answers that, not this site. Most Colorado policies pay for a sudden pipe burst, exclude groundwater and seepage, treat sump failure as an optional rider, and cap mold at a fixed amount unless you added an endorsement. Have the provider hand you photos, the moisture log, and a line-item scope before the adjuster comes.

Can we live upstairs while the crew works in the basement?

Usually, yes. The crew seals the stairwell and the returns in plastic and keeps the work zone under negative air, and the main floor stays yours. When the whole lower level is open, or someone in the house has asthma that mold sets off, the crew may suggest a couple of nights elsewhere.

Does putting the basement wall back need a permit in Arvada?

Removing and cleaning does not. Rebuilding drywall, moving a wall, or touching plumbing or electrical usually does, through the City of Arvada if you are inside city limits, or through Jefferson County, Wheat Ridge, Westminster, or Golden if you are not. Pulling it is the provider's job. Mold damage repair covers that phase.

What do I tell you when I call about mold in Arvada?

The property address, a number where you can be reached, and a plain description of where the water got in and where the growth is showing now. Call (720) 823-6943 and tell us what you see.
