How to choose a mold removal service

1. Choose the correct mold removal service

While all mold remediation companies specialize in helping rid a space of mold, not all companies do the same thing. When in doubt, feel free to ask the company of your choosing if it is one of the following:

  • A consulting company: A consulting company's main purpose is to assess a situation and recommend other experts to handle the mold outbreak.
  • A testing company: Mold testing companies take air and surface samples to determine the extent of a mold problem in a given space.
  • A treatment company: Once mold has been detected, treatment companies physically enter and help rid the space of mold with chemicals and treatments.

2. The cost of mold removal

Mold removal can be a complicated and pricey venture. Many property owners might take into consideration the cost and the various fees associated with a mold removal service before selecting a company.

  • Consulting fees: Many mold removal companies charge a fee for consulting about the mold they detect. Remember: The actual removal services are extra.
  • Testing fees: Mold removal companies often charge fees for consultation on a mold problem and test for mold when called in to assess a mold situation.
  • Full-service fees: Full-service mold companies charge fees for the consultation, testing and removal of mold in a space. These companies are often the most expensive service.

3. Mold environment

Mold grows in many places across the world, so the type of mold can vary wildly on the location it spores. The specific type of mold that grows often depends on the location’s climate and the type of toxins that thrive there.

  • Northeastern mold companies: These companies are trained in detecting mold that grows in the typical climate of the Northeastern United States.
  • Southwestern mold companies: Mold companies in the Southwest specialize in detecting and treating mold that is common in the country’s Southwest region.

4. The speed of service

Mold is a common problem, but the severity and variety of mold vary from place to place. Thus, some mold companies are able to treat mold quicker than others, which is essential when choosing a company.

  • Emergency mold removal companies: Emergency mold removal companies specialize in quick testing and detection of dangerous mold. They are also experts in treating a space to get rid of especially unsafe mold right away.
  • Standard mold removal companies: Traditional mold removal companies assess areas for mold, run comprehensive tests, then treat mold after the entire process has been completed.

5. Additional benefits

Mold companies often do more than just detect and treat mold; some companies contract laboratory and cleaning services to offer additional benefits to people who hire them.

  • Extra toxin and mold testing: Many companies offer the additional benefits of testing for dangerous environmental agents other than common mold types - such as asbestos or unsafe bacteria.
  • Litigation witnesses: Some mold companies make themselves available to serve as expert witnesses during litigation, in case a tenant or resident must go to court for a mold-related case.
  • Post-remediation testing: Another benefit mold removal companies offer is testing of the space for mold post-remediation to ensure there is not a recurrence.

6. Reputation and certification

The mold removal industry is considered to be a relatively unregulated industry, so the reputation and certification of a company can speak to its quality.

  • MRS certification: Mold companies with Mold Removal Specialist (MRS) certifications have passed an exam that ensures the company’s services meet all state licensing requirements.
  • CMR certification: Council-certified Microbial Remediator (CMR) licensed professionals have a 2-year proven track record of working and removing mold from indoor spaces.
  • CMRS certification: Companies certified with a Council-certified Microbial Remediation Supervisor (CMRS) certification have 5 years of proven experience treating and removing mold, and they are often considered the most expert mold removers.

Mold removal and remediation FAQ

Can I remove black mold myself?

Removing black mold is a difficult and hazardous operation — even a little exposure to black mold can be detrimental to your health. Experts recommend hiring a professional to remove any black mold in your residence.

If you decide to tackle this operation yourself, remember:

  • Seal all entryways from the affected area — including door crack and A/C vents — with plastic and duct tape.
  • Always wear a respirator or face mask rated for black mold at all times when working.
  • Cover all extremities; black mold can also cause skin irritation if exposed to bare skin.
  • Be patient during the cleaning process. Clear the area of black mold carefully and thoroughly.
  • Put all items used during the cleaning process into a heavy-duty garbage bag, and make sure you do not remove the bag through the residence. This limits the rest of your house from residual spore exposure.
Can mold come back after remediation?

Mold remediation is when a professional locates the origin of a mold problem and gets rid of it; however, it may not be 100% effective. There is a slight chance that the mold issue may return, usually because of an underlying water issue. When hiring a company for mold remediation, try to find one that has a guarantee that if mold returns, it will rectify the situation at no cost.

How long does mold remediation take?

Mold remediation takes anywhere from one to five days; however, many factors affect the time involved, such as:

  • The size of the mold problem
  • Location of the mold
  • What the mold is growing on
Does insurance cover mold removal?

If the source of the mold is caused by a “covered peril” according to your homeowner’s insurance policy, then you may be covered. Depending on your policy, mold removal may be covered if its growth results from:

  • An appliance malfunction
  • Firefighters’ attempts to put out a house fire
  • Openings in the structure because of wind or hail damage
  • A burst water heater

If you have questions about a specific situation and whether you have coverage for mold removal, speak to your insurance representative.

What are signs of mold in your house?

There are many telltale signs you have a mold problem in your house, including:

  • Visual indications: You may be able to spot the mold developing in an area. It sometimes appears as small, dark patches on your wall or ceiling.
  • Olfactory indications: Mold has a distinct smell that you may be able to pick up. If you find yourself frequently noticing a musty odor — especially in damper areas of your home — you may have a mold problem.
  • Environmental indications: If your home has a water leak or suffered from previous water damage, you should have it checked for mold. Mold thrives in damp environments.
How long does a mold inspection take?

On average, it takes an hour to complete; however, the length of time an inspector takes wholly depends on the size of the property and extent of the problem.

Is it safe to stay in a house with mold?

The short answer is no; it is not safe to stay in a house with mold. Most mold acts as an allergen, causing several uncomfortable symptoms, like:

  • Stuffy, runny nose
  • Sore throat
  • Various skin rashes
  • Irritated eyes

If you suspect you have a mold issue at your residence, it is best to have it resolved as soon as possible.

How long does it take for mold to grow from water damage?

Depending on the environmental conditions, mold can grow within 24 to 48 hours.

Is there a mold detection device?

There are several mold detection devices available for home testing — from basic kits costing around $10 to professional equipment that can cost around $3,500. It’s always recommended that you have an expert perform mold detection.

Do you need to be certified to remove mold?

Certain states, including Texas, Florida and New York, require licensing for mold removal.

If you are not in one of these states, ask the company you are considering if it has any other certifications, like one from the National Organization of Remediators and Mold Inspectors (NORMI).
