Eugene's drinking water, as EWEB describes it
EWEB's water comes from the McKenzie River, which flows 85 miles from spring-fed Clear Lake in the Cascade Mountains to the Hayden Bridge Water Filtration Plant in Springfield, where EWEB draws water from the river.
EWEB says Eugene has relied on the McKenzie River and the Hayden Bridge Filtration Plant for all of the city's water for over 75 years, and is planning a second treatment plant on the Willamette River as a backup supply.
Start with the damp material
Mold spores drift in on air, shoes, clothing and pets, and they can rest in ordinary household dust without doing much. What changes that is a material that stays wet: the paper face of drywall, a wood sill, the back of a carpet, a cardboard box pushed against a cool wall. Remove the moisture and growth can stall. Leave it, and a cleaned surface may grow back.
So the first conversation with any company is about water, not about the spots. Ask what it believes is wetting the area, which trade should repair that, and how it will show the material has dried before cleanup or rebuilding begins.
Gauging the size of the problem
A patch on a painted wall may be only the visible edge of growth on the back of the board, and a ceiling stain can sit under wet insulation. Before anyone quotes a price, try to learn:
- how far the damp material reaches, judged with a moisture meter rather than by eye;
- whether the wet area crosses into a closet, a second room or the floor below;
- roughly how long the water has been present, based on when a stain first showed or an odor began.
Write the answers down. A company that sizes the job from the doorway, without taking readings, gives you less to hold its price against.
Spaces a company may ask to open
Some moisture sits where nobody looks from one month to the next. A remediation company may want to look into:
- The crawlspace or basement. Damp soil, a torn or missing vapor barrier, or wet framing along the sill may only show when someone goes below the floor.
- The attic. The underside of the roof sheathing, the insulation around a vent or chimney, and the end of a bath fan duct can each carry clues.
- Wall cavities behind fixtures. The wall behind a shower valve, a washing machine box or a sink drain can stay wet from a slow drip.
- Heating and cooling equipment. A condensate pan, its drain line, or ducts running through an unconditioned space can collect water.
Ask how the company plans to look: through a small hole with a scope camera, behind a removed outlet cover, or with a test cut. Ask, too, who patches any inspection openings and whether that work is in the quote.
How a removal is staged
A careful proposal can show the job as a series of stages:
- the water source is repaired by the trade that owns it, whether plumbing, roofing, gutters, windows or heating and cooling;
- the work area is closed off with plastic sheeting and a controlled entry;
- a filtered air machine draws air out of the enclosure so it moves away from the rest of the house;
- porous material that will not be kept is cut out and bagged inside the enclosure;
- framing and other material that stays is cleaned and then dried to a target reading;
- the area is looked over and readings are recorded before the rebuild starts.
If a proposal skips a stage, ask why.
Putting the scope in writing
Ask every company for a written scope that names the moisture source, maps where the growth is, lists what will be removed and what will be cleaned in place, describes the enclosure and air filtration, and states the moisture target. Then ask what the price excludes: contents cleaning, the leak repair itself, new drywall and paint. Ask how a change will be priced and approved if opening a wall turns up more than the scope describes.
If one company both writes the assessment and performs the removal, ask how it keeps the size of the job tied to what it found. An assessment written by someone outside the removal crew gives every bidder the same page to price.
A careful first look
Before you pry off a baseboard or lift a closet ceiling panel, put on gloves, safety glasses and a well-fitting disposable respirator, and send children and pets to another part of the house. Leave dry growth undisturbed, keep fans pointed away from it, and skip the household vacuum. Health questions go to your own doctor.
Questions for each company
- Where do you think the water is coming from, and who will repair it?
- Will you take moisture readings before and after the work, and will I get them in writing?
- What state license or registration, if any, covers this work, and what is the number?
- Can you provide proof of liability coverage and workers' compensation before the job starts?
- Will the people in my house be your employees or a subcontractor's crew?
- What does the price leave out, and how will a change in scope be handled?
- What will you hand me when the work is finished?
The insurer and the permits
Call your insurer before any damaged material is thrown away. Ask what your policy says about mold and about the water that led to it, which photos and records it wants, and whether an adjuster should see the area first. If putting the room back involves new framing, plumbing or wiring, ask the contractor which city permits the work needs and who pulls them.
A closing record
When the job ends, gather the scope, the readings, your photos, the invoices and the note from whoever fixed the leak. Kept in one folder, they let you answer a later question about the work without relying on memory.
