How to choose a mold remediation company in Portland

When looking for a mold removal company in Portland, don't limit your search to the first company you find. Always do your research and compile a list of your top choices. Before choosing any company, you should ask:

  • Does the company deal with black mold?
  • Is the company experienced with removing mold in similar situations?
  • How long does mold remediation take?
  • Does this company have any guarantees?

You improve your chances of successful mold remediation if you work with a company that's familiar with common causes of mold in Portland. These mold removal services can identify the source of mold growth and prevent it from returning.

Remember to focus your search on a business that offers what you need — if you had a pipe burst in your home, you need emergency service and repair. The median size of a home in Portland is 2,300 square feet, so mold removal can be a large job. To help identify reputable companies, see if they hold certifications from professional organizations such as the National Organization of Remediators and Mold Inspectors and the National Association of Mold Professionals.

Portland mold removal FAQ

How much does mold removal cost in Portland?
Professional mold removal in Portland usually costs $1,114 to $3,339. However, the cost varies based on several factors, including the size of the problem, the type of mold and how difficult it is to access.
How long does mold remediation take?
Generally, mold remediation takes one to five days, but this varies depending on your situation. A small area with surface damage is much easier to fix than a large area with structural damage.
How much does a mold inspection cost in Portland?
Mold testing or inspection in Portland ranges from $292 to $1,016. Much like mold removal, the cost depends on your situation. The size of your home also plays a significant role in the price.
How much mold exposure is harmful?
Any exposure to mold can be harmful to your health. Prolonged exposure is more likely to cause issues than short-term exposure. If you suspect you’re exposed, you should get your home tested.
What kills black mold?
Bleach and borax can be used to kill black mold. However, the chemicals alone are not enough. The mold isn’t just on the surface of your walls or ceiling — your problem goes deeper than that. An expert needs to examine the area to determine the severity of the growth and how to treat it safely.
