How Mold And Mildew Form
Mold and mildew need the right conditions for growth. To begin, they need mold spores as a type of seed. Spores grow with three factors: food , water, and oxygen. Increasing or decreasing any of these factors will cause mold and mildew to grow or die.
Spores land on the surface, germinate, and grow. Mold and mildew may start as early as 24 to 48 hours after the surface has been dampened. Mildew’s white-gray spots spread outward, not upward, remaining on the surface. Mold, though, eats into its basewhich makes it harder to removeand sometimes grows upward.
How To Kill Mildew On Untreated Wood Surfaces
Mildew has a way of creeping up and spreading where you dont want it to be, like on your wood deck, flooring and furniture. When you see mildew on wood, it can start out looking white or gray but can then turn much darker, becoming brown or even black. Luckily, there are natural ways to get rid of mildew, but you may need to use mold removal products to remove it completely.
Clean Up And Dry The Affected Area
Once you have completed the scrubbing and sanding to remove mold, you want to make sure to finish cleaning up the area where you worked.
Start by collecting and throwing out any residue and other items that have come into contact with the fungi. The residue that stays on these items can grow into new mold growths, so you want to be sure not to leave any around.
Next, take a final pass at the area you worked with new cleaning items such as rags or paper towels. This extra step will help prevent mold from spreading again.
Finally, make sure the area you worked dries fully. If youre working with furniture, place it in a well ventilated and dry area. If youre working on walls or floors in an area with minimal ventilation, you may need to use fans to dry the surface. In either case, take all the time it needs to ensure the surface is dry.
Test the cleaned surface both by sight and touch. Once you are sure the surface has dried thoroughly, be sure it does not get wet again.

The most effective way to prevent mold from growing on wood is to keep the wood surface dry. To do this you will need to dry wet areas as soon as possible. Its also crucial to control the humidity and moisture levels of your home keep humidity under 60 percent .
You can minimize the humidity by using a dehumidifier, as this will remove moisture from the air. You can also open the windows as often as possible to ventilate the rooms and allow fresh air to circulate.

Does The Building Need To Be Sterile Is The Object To Reach A Mold Spore Count Level Of Zero
No, the building does not need to be sterile, nor should you seek a “zero mold count”. We have worked on cases where sterility was a necessary cleanup goal: medical facilities such as in operating rooms and treatment rooms. But in a normal office or home there is always some airborne mold along with lots of other airborne particles in building dust.
No washing, sanding, scraping, or other surface cleaning will remove all mold spores from wood where mold was previously found. It is unlikely that most construction materials, even when new, are free of mold spores, nor is”zero mold” a reasonable nor possible objective.
Cleaning moldy framing lumber followed by application of a sealant may be the most cost effective alternative . While lumber replacement with apparently “clean” new lumber may sound appealing, it is likely to be cost prohibitive and in fact may include its own mold when it is unloaded at the work site.
The Bottom Line: Its All About Moisture
Moisture is the essential ingredient for mold to thrive, and it can come from many sources. If an area has gotten wet for any reason, dry it within 24 to 48 hours, before mold has a chance to grow. The most common sources of moisture are plumbing leaks, roof leaks, wet basements, poor yard drainage, window condensation and high humidity. These myths about mold will set you on the right path for solving your mold issues.
If porous surfaces such as carpet, drywall or ceiling tiles have gotten moldy, remove and replace them. Your houses humidity should be 30 to 60 percent from spring to fall, and about 20 to 30 percent in the winter. If its high, use air conditioners or dehumidifiers. Use an exhaust fan ducted to the outside when youre cooking. Install and use a timer on your bathroom exhaust fan. It should run for at least 30 minutes after showers. Myths about mold busted!

How Much Mold Must Be Removed
Following a properly executed mold cleanup, if there is a future mold problem in a building it is unlikely to be due to having left behind an “inoculation” of problem mold, and more likely to be due to a new building leak that was left unattended.
Good practice for the extent of and means of physical removal of moldy debris varies by material.
For drywall we remove all visibly moldy material and continue removing drywall to no less than the next adjacent stud, rafter, or joist.
For fiberglass or other porous building insulation which has been wet, we remove all suspect insulation and all insulation within 24″ of the suspect material. However if moldy and wet conditions were long-standing in a building, removal of all of the insulation may be necessary.
For building insulation that has been exposed to dusty conditions or high levels of airborne mold it is often more cost effective to simply remove the material, clean the surfaces, and re insulate than to spend that same money on testing the insulation for mold.
Generally it is less costly to remove and discard more material than to “finish” the job and then discover that it needs to be done over again because the initial work was insufficient.
Framing lumber, or roof or wall sheathing that is not rotted does not need to be replaced. Unless framing lumber has been actually damaged, such as by rot, replacing it due to mold contamination is not justified and wouldbe improper.

The Path Of Resistance
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.
How Long Does It Take To Kill Mold
The amount of time it will take to kill mold will depend on how much mold youâre dealing with and what type of cleaning product youâre using to remove it.
Your best bet is to refer to our recommendations about how long the solution should dry. If you notice that there still might be mold after cleanup, try the solution again or test a different one from above.

Dont use your nice clothes, as this is dirty work! The last thing you want is stains on your favorite jeans when youre battling mildew.
