MOLD REMOVAL · PROJECT PLANNING
How to compare mold removal estimates
A useful mold removal estimate should explain what caused the moisture, what will be cleaned or removed and how the work will be checked. Ask about those details before you compare prices.
Two companies can inspect the same room and propose different work. One may quote for cleaning visible surfaces. Another may include removing damaged material and rebuilding it. Put the scopes side by side so you can see what each price covers.
First, decide what kind of help you need
Not every small patch needs a professional cleanup. EPA says that, in most cases, an area smaller than about 10 square feet can be handled using its cleanup guidance. Extensive water damage, a larger affected area or contaminated water needs different consideration. EPA recommends an experienced professional for damage caused by sewage or other contaminated water. If you have health concerns, consult a health professional before cleanup. Source: EPA, Mold Cleanup in Your Home.
If you hire a company, ask about experience with a project like yours and check its references. Describe the affected rooms, any known leak and whether there is still water present. Avoid disturbing hidden areas just to provide a more detailed description.
Separate the moisture repair from the cleanup
Moisture control is central to mold control. An estimate should make clear who will investigate and correct the water problem. Cleaning the visible surface does not explain how that cause will be addressed. Source: EPA basic cleanup steps.
Ask whether finding and fixing the cause is included in the proposal. If another trade is needed, identify that handoff. You may need plumbing help for a leak or water damage restoration for a separate water-removal and drying job.
Ask what stays and what goes
Have the contractor list the affected areas and materials. EPA notes that moldy porous materials, such as ceiling tiles and carpet, may need to be discarded because mold can be difficult to remove from them. Painting or caulking over a moldy surface is not a cleanup plan. Source: EPA basic cleanup steps.
- Which surfaces will be cleaned?
- Which materials will be removed, and is disposal included?
- How will the company protect adjacent areas during the work?
- Does the price include replacement drywall, flooring or decoration?
- Who approves a change if hidden damage is found?
Understand any testing charge
EPA says sampling is usually unnecessary when visible mold is present. There are no federal limits for airborne mold against which a sample can establish compliance. Sampling can have a specific use, including assessing cleanup, but needs an experienced professional who can design the sampling and interpret its results. Source: EPA, Mold Testing or Sampling.
If testing is proposed, ask what question it answers, who will perform it and how the result changes the work. A test result needs an explanation, not just a pass or fail label.
Agree on the finish line
Ask what the contractor will check before calling the work complete. EPA’s guide says the moisture problem must be fixed and the mold removal completed. It also recommends revisiting the area to check for renewed water damage or growth. Source: EPA’s mold and moisture guide.
Request a written scope, exclusions, schedule and process for extra work. Keep your copy of the proposal and any photos or reports the company supplies.
