Bathroom Mold Removal in Arvada, CO

The hall bath in your brick ranch has a window and no exhaust fan, the way most of them were built in 1962, and the ceiling above the tub grows gray speckles every winter no matter how many times you repaint. This year the vinyl in front of the tub has gone soft, and the baseboard behind the toilet is dark at the bottom. This site connects you by phone with an independent local provider who does bathroom mold removal in Arvada and across Jefferson County.

Three sources, one room: steam, a pan, and a supply line

A bathroom grows mold for three reasons and the crew sorts out which one you have before cutting. Steam with nowhere to go, in a room with a window the owner keeps shut from November to March, condenses on the coldest surface, usually the ceiling and the exterior wall. A failed shower pan, a cracked tub drain, or grout that has opened puts water under the floor every time someone showers. A supply line or an angle stop that weeps under the vanity wets the cabinet floor and the wall behind it.

They meter the ceiling, the exterior wall, the floor around the tub, and the vanity wall, and look below: in an Arvada ranch the bathroom usually sits over a finished basement ceiling or a utility room, and a wet subfloor shows there first. The reading sets the scope and tells you which trade has to fix the source.

Open the window, stop using the shower, and look in the basement

Until the crew has seen it, shower in another bathroom if you have one, and leave the door and the window open after any use. Put a towel under the vanity and check it in a day for drips. Do not scrape or bleach the ceiling; the speckles are the surface of a damp drywall sheet, and the paint over them traps the moisture.

Go to the basement and look at the ceiling and the wall directly under the bath. A stain, a soft drywall patch, or a water line on the ductwork there means the floor or the drain is the problem, not the steam, and the job is bigger than the ceiling.

Ceiling drywall, subfloor, and vanity wall removed to dry wood

The bathroom is sealed at the door with plastic and a HEPA scrubber runs under negative pressure. Ceiling drywall with growth comes out to the meter line, insulation above it that got damp is replaced, and the joists are HEPA vacuumed and cleaned. If the floor is the source, the vinyl, the underlayment, and the wet subfloor in front of the tub come out, and the crew tells you whether the pan or the drain has to be replaced before the floor goes back. A wet vanity wall is opened and the cabinet base is pulled if it has swelled.

Air movers and a dehumidifier run until the framing reads dry. A fan that vents into the attic instead of outside is a roof-side problem covered under attic mold remediation. A basement ceiling below the bath that got wet is mold removal. New drywall, tile, vinyl, and trim are mold damage repair.

No-fan baths, winter windows, and bathrooms stacked over finished basements

Most of Arvada's 1950s to 1970s housing, from Lamar Heights and Alta Vista to Far Horizons and Scenic Heights, was built with a window as the only bathroom ventilation, and the exterior wall in those baths is brick on block with little insulation. Winter steam meets a cold wall and ceiling in the same room every day for five months. Where a fan was added later, it often vents into the attic rather than through the roof, which moves the problem up a floor. The newer houses in Candelas, Leyden Rock, and West Woods have fans and insulation, so their bathroom calls are almost always a pan, a drain, or a supply line.

Colorado has no mold license, and the provider represents its own training. Replacing a shower pan, a drain, or an angle stop is plumber's work licensed by the state, and adding a vented exhaust fan is electrical work with a City of Arvada permit. A drain leak that has been going for months is usually excluded from a Colorado homeowner policy as a slow leak, so tell your adjuster when the floor first felt soft.

Calling about a bath that will not stay dry

Have the address, which bathroom it is, whether it has a fan that vents outside, what is below it, and whether the floor is soft. Say whether a plumber has already looked at the pan or the drain. Call (720) 823-6943.
