How much does mold remediation cost?

Asked by Jeff, Livonia, MI Thu May 7, 2009

I looked at a foreclosed home today in Livonia (#29057696), and it appears to have a major mold problem. The basement flooded this past winter due to a water pipe breaking. Perhaps the house was not properly winterized? I noticed extensive mold damage where all of the basement ceiling joists, heating ducts, and the underside of the main floor are all covered with mold due to the moisture resulting from the standing water in the basement all winter. I saw some black spots on the kitchen wall, but I have no idea how bad it is behind the walls or elsewhere. All of the hardwood floors in the entire house are warped and buckled. How much would it cost to repair that as well? Have any of you ever seen it this bad before?

Small projects can be done by the homeowner. But its a good idea to be careful and hire a pro. Specially if the mold is inside walls.
See video here of a pretty bad case of mold - and tips for whether to do it yourself or hire a pro.

I think it depends on the company you choose to hire. I would call around to businesses around your area and see what the average cost is that you're looking at. I think that will give you the best idea of what you're looking at paying. Good luck and I hope everything works out for you!

Hi Jeff,

I am a contractor and have done several mold abatement jobs throughout MI in foreclosed homes. Chances are if you can see it on the floor joists in the basement and the underside fo the main flooring, the plywood may need to be replaced. Depending on how "bad" the situation is, you could be looking at $2,000- $5,000 for remediation alone. As far as making the repairs to the flooring, drywall, and plumbing, it again, depends on the extent of the damages.
If you need a reliable and dependable contractor let us know. We offer 3rd party air quality testing as well. We are licensed, insured, and have our CMR certification.
We have also done work with homeowners who have done the 203K loan that Jeremy was referring to also.

Best of luck!

Mold removal costs would depend on how large is the affected area. It is always good to hire experts as they can provide you with a cost estimate.

It really depends on how much area has been affected by mold. I would imagine water build up resulted in the mold. It can be very hard to remove water at times because it takes very little time to stain and start causing problems. Identifying the issue quickly and having the right professionals care for the area is key to preventing the development of mold or fungi.

Some of the things we consider when determining mold removal costs are:

- Size of the area that has been affected by mold or water damage.
- Amount of building materials that need to be removed due to mold or water damage (if any).
- Cost to build back building materials that have to be removed.
- Difficulty of access to the affected area (crawlspaces, attics and other confined spaces).
- Length of time it will take to complete the job.
- Amount of machinery we need for the job (negative air machines, HEPA vacuums, airless sprayers, containment chambers, hydroxyl and/or ozone generators, dehumidifiers, air movers, anti microbial and fungicidal solutions, mold-proof coatings).
- Number of mold remediation technicians needed on the job site.

Depending on the size of the mold removal project, cleaning up mold in your home or business can vary greatly. Please remember that we are not simply tidying up or cleaning everyday household dirt - we are removing mold -a biohazard that can cause severe health issues in many people and cause damage to your property. Missing a little dirt is no big deal. Missing a little mold contamination can have health and property damage implications.

There are a lot of companies that offer blind discounts on mold removal project that promise to beat any competitor’s price. Some companies will even quote you over the phone without seeing the job. I would recommend against those companies because they tend to be more about the money than doing the job correctly.

As a professional mold remediation company, we charge what it takes to safely and effectively remove your mold contamination.Not more, not less. In many cases, it is necessary to perform moisture mapping, thermal imaging and a visual inspection to determine the cost of your mold removal project so be cautious of those who don't do these things. Sometimes, mold testing is necessary to determine if the air-born mold levels are elevated as compared to the outside (normal) levels.

Bottom line is that every job is different and every job has different costs. We can usually provide general pricing while on-site but always follow up with a written scope of work with specific pricing. Best of luck - Tom, Mastertech Environmental.

It Depends. Depending on the extent of the damage and what is needed to restore to a normal level of fungal activity prices will vary. Ensure that you are knowledgeable on the process by doing your own research as well as contact several companies and compare how reputable and knowledgeable they are on advising what can be done to assist. Great info can be found from this NJ mold company's site.

Make sure the humidity in doors is below 60%, with and ideal percentage being between 30-50.
Any wet damp spots need to be cleaned and dried within 48 Hours.
HVAC inspections need to be regularly scheduled
Make sure appliances that generate moisture stay ventilated, i.e Dishwashers, Refrigerators
Keep your air conditioning, heating, and ventilation drip pans clean, unobstructed, flowing properly
Fix leaks and plumbing problems as soon as possible
Making sure there is proper drainage, to prevent backup, and a dry foundation
Do not run the HVAC system if you suspect mold. Call mold contractors for mold testing.
These methods can prevent the need for Mold Remediation.

Listen guys/gals. Poor people like me DO NOT have the financial resources to do mold remediation "by the book". Believe me, I'm not stupid or ignorant of what mold can do, but which should I choose. Taking care of water getting into my basement by having outside drainage installed around perimeter of home ($3,500), or mold remediation services? I can't afford to do both. I've been having sinus problems since we experienced heavy rains lately and had some water in our basement. Is it because of mold? Perhaps. But what the heck am I supposed to do about it when I can't afford the remedy? I'd gratefully do what needs to be done myself if I could work out a deal with a mold remediation contractor in which I do all the work in return for their guidance and a reduced price. I've had a dehumidifier and fan going approximately 8 hrs. each day after the initial heavy rains. I'm just a 50+yr. old lady with a very bad back and little to no financial resources.

I think that you will really want to get some work done on your mold problem. Mold can be a very serious problem and it can be dangerous. The cost of the mold remediation depends on a couple of different things. I would strongly suggest that you get it done soon!

We had trouble with mold a few years back. It happened as a result of a little basement flood we experienced. Turns out that if you don't get things dried up really quickly, they'll mold all the way through in just a few weeks. It ended up taking a lot of time and effort to get it all fixed.

If you are truly interested in the home, I would get a mold inspection and get a quote for mold remediation from a licensed professional.

There are a few options you have when dealing with water damage. I would recommend finding a flooded basement repair service that can come in and take care of it for you. Trying to fix it yourself can turn into a stinky, wet, and frustrating mess.

Mold removal can vary a lot in price. It depends on how extensive the damage is. You might see if a professional can come out just to look at it first and assess the damage. They would be able to give you an estimate according to your specific situation.

Mold remediation alone can cost anywhere between $1,800 and $2,200 per day depending on the size of the area and how saturated with spores it has become. This cost could rise depending on how many certified techs are needed as well. This cost includes minor repairs. However, major repairs will inherently cost more. Source:

This can depend on several things, the type of mold and the extent of the damage. Your best bet is to call someone that specializes in this, It can be very extensive and expensive. Mold Stoppers in Garden City would be a good place to start 888-620-MOLD(6653) or

I would suggest that you post this question under remodel and renovate. You might get more specialized responses.

I have seen things this bad and depending how high the water got and how much food (paper goods/wood) there is for the mold it could get real bad!. You may have to strip it down to the studs and may even have to replace the studs. You really need someone that is experienced in mold. It can be bad or it can really be bad!

This is not something you should do unless you know what your doing. I would also again suggest to post under remodel and renovate.

Good Luck.

I'm glad you're here! Its pretty common to see bank owned homes needing this amount of work or more. I think you said it best in the third line up from the bottom "I have no idea how bad it is behind the walls or elsewhere". I think you will end up with the same answer when you attempt to put estimates from contractors together.

I would recommend talking to a few contractors before considering making a move to purchase. If you need a referral ask your Realtor for some assistance with a referral, you are working with a Realtor correct?

I am unaware of your financing position, unless you are a cash buyer you may want to make sure that the home is even mortgageable before you do too much homework

If you plan on obtaining a mortgage has anyone explained a 203k/renovation loan and how it works?

Best Wishes

Hi Jeff,

Cleaning up mold can be a costly ordeal. Your best course of action is to hire a mold inspector to come in inspect the property and then issue a report and quote to clean up the home. A contractor will be your best option for a quote on how much it would cost to repair the flooring throughout the home. Since you have not made an offer to purchase the home as of yet you could always ask the listing agent if the seller has completed a mold inspection. Good luck.
