If you've spotted mold in your Minnesota home, you're probably wondering how much it's going to cost to get rid of it. Trust me, I've been there—finding mold in your basement or bathroom is stressful enough without worrying about the bill. The good news? Mold removal costs in Minnesota are often more reasonable than homeowners expect, though prices can vary quite a bit depending on where you live and how bad the problem is.
Let me break down what you're actually looking at for mold removal in the Twin Cities, Greater Minnesota, and everything in between.
Here's what homeowners in Minnesota are typically paying for professional mold removal in 2025:
Small jobs (under 10 square feet): $500–$1,200. This covers minor mold spots in bathrooms, closets, or small basement areas. Many companies have a minimum service charge, which is why even tiny mold problems can start around $500.
Medium jobs (10–50 square feet): $1,200–$3,500. This is more common than you'd think. Maybe you've got mold on a bathroom wall, under a window, or in a crawl space. Most people end up in this range.
Large jobs (50–100+ square feet): $3,500–$8,000+. When you're dealing with extensive mold in walls, attics, or multiple rooms, costs climb quickly. Some jobs in this category can go even higher.
These are ballpark figures, and your actual cost will depend on several factors we'll get into next.
Not all mold jobs are created equal. Here's what drives prices up or down:
Location and accessibility: Mold in easy-to-reach areas (like a basement wall) costs less than mold hidden inside walls or above drop ceilings. In Minneapolis and Saint Paul, where older homes with complex construction are common, you might pay more for jobs that require demo work.
Type of mold: Black mold removal typically costs more than other types because it requires specialized equipment and protocols. If you're in Rochester or Duluth and dealing with black mold, expect to pay on the higher end of the range.
Extent of the problem: This is obvious, but a small patch in one bathroom is way cheaper than mold throughout your HVAC system. Square footage matters, and so does how deep the mold has spread.
Underlying moisture issue: Here's the thing—if the mold came back, it's because moisture is still there. Some jobs include finding and fixing the source (like a roof leak or grading problem), which adds cost but saves you from dealing with this again next year.
Testing and inspection: Most companies will do a visual inspection for free, but if you want lab testing to identify the mold type or confirm it's gone, that's usually $300–$700 extra. Some homeowners in Saint Paul skip this, while others consider it worth the peace of mind.
Minneapolis and Saint Paul: Being the metro area, you'll see slightly higher prices here. A medium-sized job that runs $1,500–$2,500 in Rochester might cost $1,800–$3,000 in the Twin Cities. There's more competition, but also higher overhead for contractors.
Rochester: Mold removal here is generally more affordable, partly because the cost of living is lower. You can get solid work done for the lower end of our ranges listed above.
Duluth: Similar to Rochester, though moisture problems can be unique in the Duluth area with its lake proximity and humidity patterns. You might actually need more thorough moisture control work, which could increase costs.
The truth is, it's worth getting quotes from multiple companies in your specific area. Price differences between contractors can be significant, and so can the quality of their work.
Before you agree to any estimate, make sure you know what you're actually paying for. A good mold removal company should include:
Some companies throw in a follow-up inspection at no charge. Others charge extra for things like moisture testing or mold-resistant primer during repairs. Ask about this stuff before hiring someone.
Sometimes, but usually not in the way you'd hope. Most standard homeowners policies don't cover mold removal if it's due to poor maintenance or a slow leak. However, if mold resulted from a sudden, covered event (like a burst pipe), you might have coverage. Call your insurance company directly—don't rely on the contractor to know your policy.
For tiny spots smaller than 10 square feet, you can try DIY removal with bleach solution and a HEPA mask. But honestly? Professional removal isn't that much more expensive, and they know how to do it right the first time. DIY mold jobs often lead to incomplete removal and the mold comes back in a few months.
Small jobs take a day or two. Medium jobs might take 3–5 days. Large jobs can take 1–2 weeks, especially if the contractor needs to wait for materials to dry or if structural repairs are involved.
