Option 1. DIY Attic Mold Removal

Before you head up to the attic, keep in mind that it is one of the most dangerous places in your home. The reasons are obvious, it is elevated and you need to do some climbing before you get there.

One slip and you could come crashing down and cause yourself some injury. Besides taking a hard fall, other potential hazards can be found up there.

These include nesting animals, bare electrical wires, and protruding nails. All these can leave you startled, electrocuted, and pierced in the foot.

This is why you have to take caution when doing any sort of work up there, not just attic mold remediation.

How To Remove Mold From Attic Plywood

If your attic has a moisture problem, then you can expect mold to grow on the plywood. Removing mold from plywood isn’t difficult, just follow the steps below.

Inspect the attic: The first thing you need to do is inspect the attic and make sure it is safe for you to work.

If there are naked wires or nesting animals in there, we advise you to forget it and call the pros.

Wear protection: If after your inspection you find that you can safely work in the attic, then you can proceed.

But you still need to put on a pair of rubber gloves to protect your fingers from touching the mold and cleaning substances.

You should also put on a pair of goggles and a facemask to guard your eyes and nose against mold particles. These can also keep you from inhaling harmful chemicals contained in a mold removal spray.

Use attic mold removal spray: These sprays are designed to remove mold from attic plywood and other areas they may have settled. It can also be used to remove mold from attic rafters and ceilings.

You can buy the spray from a home improvement store near you to fight attic mold. All you have to do is read and follow the instructions on the container for the best results.

To use this spray, aim at the affected plywood and spray the content across. Wait for as long as the manufacturer asks you to before wiping the mold off with a dry cloth or scrubbing it off with a brush.

Keep in mind that the way you use the product will depend on each manufacturer’s specific instructions.

It is also worth mentioning that bleach isn’t the best product to use for plywood mold removal. This is because bleach cannot penetrate the pores of the wood, it can only work on the surface.

How To Remove Mold From Attic Sheathing

There are several approaches by which you can use to remove mold from attic sheathing.

These include the following –

  • Hand sanding
  • Encapsulation
  • Dry ice blasting

While sanding and blasting are effective in removing mold from attic sheathing, using fungicides as insurance is still advisable.

Let’s not forget, dry icing can be pretty expensive so you have to consider the cost first.

Option 2: Professional Attic Mold Remediation

Getting rid f black mold in the attic is far from an easy task, and this is why you might want to consider hiring a professional.

We have already listed out the dangers involved with climbing up there, and why it is a job best left for seasoned pros.

Besides the dangers involved, it is really a complex job, especially if the mold infestation is really bad. A person with little to no experience who decides to do the job on his or her own will probably get it wrong the first time.

In this instance, the mold situation could actually go from bad to worse, as the household may become further exposed to the hazardous effects of mold.

Hiring a professional will indeed cost you a decent sum in mold removal fees, but you can rest assured the job will be properly done.

One thing you can expect a professional to recommend is abrasive blasting. Here, the contractor will blast off the top layer of infested wood via dry ice, sand, or soda ash.

As you can imagine, this procedure is expensive, and that is why it isn’t such a popular option. It is also a very noisy and labor-intensive method of attic mold removal, so you can expect some inconveniences at home while work is ongoing.

However, it is a very thorough approach and it guarantees that the mold in your attic will be gone.

You can save money by fixing the water issues yourself, but don’t think that will instantly remove the mold. Agreed, fixing the water issues can ensure mold doesn’t return to your attic, but that’s a long-term fix, not instant.

If you want the mold gone today, then you have to make moves today.

Conclusion

You can either remove the attic mold yourself or hire a professional to do it for you. If you insist on the DIY approach, then you can remove mold with a simple attic mold removal spray.

However, you have to first understand the risks associated with attic work before you begin. Do all you can to protect yourself while you work.

Professionals will be more thorough though, as they will employ more effective, more expensive attic mold remediation methods.

The choice is yours.

Good luck!
