Basement Mold Removal Cost

Getting Rid Of Mold And Mildew In Your Basement

If you decide to take a do-it-yourself approach to removing the mold problem in your basement, the cost will depend on the products you use for mold removal.

While getting rid of mold infestation in basement may seem daunting at first, below are a few steps to take to ensure that youre successful.

Your first step to removing mold in your basement is to figure out what kind of mold youre dealing with and identify it correctly. Mold inspections is of utter importance.

And, depending on the type of mold in your basement, youll need to take special precautions such as wearing a mask or respirator to ensure that you dont breath in harmful toxins.

Ensure that any air vents are sealed off so that mold spores dont spread to other areas of your home. Also be sure to check all crawl space in your basement.

Once youve removed the mold, you may want to consider taking extra precautions such as a negative air pressure system or HEPA vacuum.

Take steps to make sure the area has good ventilation. You may want to set up a dehumidifier to try to keep the area non-humid and well ventilated to prevent future mold growth.

Costs of do-it-yourself mold removal can range anywhere from $25 and upwards. The potential costs of your basement mold removal plan will also depend on the type of mold youre attempting to eradicate.

And, there is a mold removal cost directly dependent upon what kind of equipment is required to remove the fungus.

What Causes Mold To Grow In Basements

Mold loves temperatures between 60 and 80 degrees F, a little bit of moisture, some tasty surfaces to feed on, and plenty of room to growall of which the average basement supplies readily.

You can have issues with mold after a small leak, say, from a water heater or bathroom, rain coming in a basement window after a big storm, a major flood event, an overwatered plant pot, or even just due to an excess of indoor humidity.

The white, fluffy substance is efflorescence and the black spotting on the wall is mold growth. Efflorescence occurs when moisture moves through the concrete and deposits minerals/salts on the surface. In a basement, this can be a complex issue. First, I recommend looking at your downspouts and ensure they are moving the water far away from your home. Your goal is to reduce the moisture load in the soil near your home.

If this doesnt solve the problem, youll likely need a sump pump and possibly an interior footing drain. While expensive, they are often the only way to completely solve the problem. In most cases this will involved removing the wall in the problem area so the footing drain can be installed at the very edge of the concrete slab.

Dealing With Outdoor Causes Of Mold

Since there are two main causes of mold , we are going to take the same approach to mold prevention. Lets dig deeper into outdoor moisture causes and what you can do to prevent moisture inside your basement.

First of all, you should be aware of rains and floods as they are a direct source of water. Following the flow path of rainwater or the access part of flood will give you enough information to start with.

Pay attention to where the rainwater flows after it falls on your roof. If the ground surrounding your home is on the same level as your home or higher, it is very likely that rainwater is going to get into your basement. Talk to your contractor to have the outside ground slope away from your home or heap soil onto the ground against your home.

Rain can cause a problem without even touching the ground. The windows on your home may be a problem too. Inspect your windows and check window wells for signs of insulation problems or potential build-up issues.

Additionally, do not forget to clean the gutter to ensure proper water flow. Ensure that all downspouts extend far away from the home, especially if the grading is not optimal. That way you will ensure that rainwater flows away from your home, not into it.

Another outdoor cause of excess moisture, although not a frequent one, is flooding. Its almost impossible to prevent floodwater from coming into the basement but it is crucial to act the minute it happens, in order to prevent mold from growing.

Dont Ignore The Problem

How To Get Rid Of Mold In Walls

If the wall is made from a non-porous surface, such as finished wood or stone, it must be thoroughly dried. A dehumidifier, proper ventilation or a wet vacuum can be used. Then, a damp wipe down of the area should remove most of the mold. Cleaning products designed for mold removal are helpful, however it is not necessary to bleach moldy areas or use other biocides. If the wall is made from a porous material such as gypsum drywall, wallpaper or unfinished wood, it is not possible to remove all of the mold from the tiny nooks and holes in the wall. The affected section of the wall must be cut out and replaced. This can be very expensive. However, the mold will almost certainly come back otherwise.

Finish the mold removal by using a vacuum with a HEPA filter. A non-HEPA vacuum may not contain the mold spores and can actually spread them into the air. Vacuum the entire area and surrounding areas, even if no mold is visible.

Do not just paint or caulk over mold without removing it. According to the EPA, this will cause the paint to flake and peel, and when the paint comes off, you will still have mold on the wall.

Mold On Basement Floor

Black mold can also take over the basement floor. It can be caused by leaking pipes, poor drainage or lack of ventilation. To eliminate it, fill a spray bottle with water and spray the floor, then scrub the floor with a stick scrub brush as much as possible. Then, mix water with ammonia in a bucket, and use a scrub brush to clean the floor. Once done, use water to remove all the remaining soapy water from it. Next, prepare a mix of bleach with water and scrub again. Leave the bleach for several minutes and then clean again with plain water to remove the bleach. Dry the floor ensuring to remove all moisture from it. Finally, use a dehumidifier to keep the area moisture free.

Lets briefly delve into the science behind mold. Your unwanted home invader is the result of fungi species that generate spores to reproduce.

When these teeny-tiny spores, invisible to the naked eye, land on something wet, they start to grow. Theres no way for mold to thrive and survive without moisture .

Now that youre versed in mold 101, you can likely anticipate what the causes would be. These are the reasons why your basement could have been affected:

  • After flooding: A flooded basement is an optimal environment for mold. Standing water and damp items such as furniture and carpets can serve as breeding grounds.
  • Water leaks: As with post-flood moisture, leaky pipes, appliances or drains in your basement will increase your risk of finding a moldy surprise.
  • High humidity: If the old stereotype of your basement as a damp and dank place applies, your chances of mold will be higher. Humidifiers, air vents and similar steamy gadgets or mechanisms can all encourage mold.

Removing mold from wood is easy if it has not spread far and wide. Before starting, put on your protective wear, especially a mask and gloves. First, vacuum up the area with the mold. This will suck up any loose spores on the surface of the wood. Next, scrub the area with soap and water. On bare, untreated or unpainted wood, you can use bleach. Soak up any cleaner and extra moisture.

If mold is still apparent in the wood, you can try to sand it out. Note that sanding will take off any finish and some of the wood. Since mold can live deep in the pores of wood, you may need to do a lot of sanding to fully remove it.

How To Prevent Mold Growth In The First Place

According to the Environmental Protection Agency , There is no practical way to eliminate all mold and mold spores in the indoor environment the way to control indoor mold growth is to control moisture. Even if you clean the mold, it will still come back if the room is humid and poorly ventilated or there is excess moisture from a leak, even a small one. Humidity levels should never exceed 50% to control mold growth.

That means prevention is the only permanent remedy for mold. After you’ve repaired the leaks and gotten rid of any moisture problems, moving forward, create an environment where mold cant grow with these tips:

  • Add a dehumidifier or two to your home. Its best to keep indoor humidity levels between 30-50% to stop build-up make sure to buy one thats sized for the area you are treating.
  • Open bathroom doors and windows or turn on the exhaust fan during and after showering to let moisture escape.
  • Leave your shower curtain or liner spread open after showering to help keep it dry.
  • Vent moisture generating sources, such as bathrooms and clothes dryers, to the outside.
  • Avoid storing items in damp rooms, which may mean keepinglinens, books, or furniture our of your basement or attic.
  • Seal bathroom grout lines every year if you have tiling. This will help waterproof your walls and floors.

How To Get Rid Of Moisture In The Basement

Moisture is a common problem in basements. A damp or musty smell is unpleasant whether you have an unfinished, partially finished, or fully finished basement. Even if you rarely use your basement ductwork, other connecting airways can bring unpleasant odors, mold or mildew into the rest of your home.

The Path Of Resistance

Getting Rid Of Basement Mold

Initially, Mikes landlord tried to fix the problem himself, bleaching the moldy walls. We call that spray n’ pray, said Scott Armour of the Institute of Inspection Cleaning and Restoration Certification, a global industry body for remediators. They, along with the EPA, advise against bleach for a variety of reasons, namely that fumes can be dangerous and its usually ineffective.

Bleach only works for non-porous surfaces. It cant touch the mold that has burrowed into surfaces like wood or drywall . But the most important reason bleach fails is that people dont stop the molds water supply.

First thing I do is check for leaks, in the bathroom or roof or a crack in the foundation, said Greg Bukowski, who runs the Chicago-based remediation company Moldman USA. Theres always a leak. If you dont fix that, dont bother with bleach or vinegar. Then kill and remove the mold with detergent and water, then prevent its return with mold-resistant paint like Kilz .

When bleach didnt work, Mike paid for an indoor airborne mold test, which raised more questions than it answered. We had no idea how to interpret the results. I just couldnt find any information out there that isnt written by remediation guys, he said. They told him he had the dreaded black mold, and needed professional remediation.
