The True Cost Of Mold Remediation

What is the true cost of mold remediation? Mold remediation can be an extensive process taking anywhere from a day to a week to conclude. In this article, we will help you identify the extent of your mold infestation and how to select a company that knows how to get the job done and at a fair price.

How Do You Know If You Need Mold Remediation?

Signs & Symptoms Of A Mold Infestation

  • Unexplainable rashes, itchy eyes, coughing and wheezing
  • Musty, earthy smell
  • Visible patches of mold
  • Recent water leakage, flooding or water damage (e.g. leaking pipes, flooded basement, leaking roof etc.)
  • Discoloration, warping, splitting, peeling on walls, floors or ceilings
  • Unusually dirty tile grout lines

Mold Remediation Pricing 

One thing to be aware of: just because you can see patches of mold, doesn’t mean you are seeing all of the mold. Mold can penetrate just about any surface of your home. If you’re seeing even small patches of mold along your wall, there’s a decent chance that behind that wall, and others, there’s more than enough mold growth to exceed the 100 square foot EPA guidelines for DIY mold remediation. When in doubt, have a certified professional service perform an inspection.

Does DIY Mold Removal Save You Money?

While EPA guidelines state anyone with a spray bottle can handle an infestation covering 100 square feet or less, as a home or business owner, how do you know you’re dealing with an infestation of 100 square feet or less? Is there more mold behind the walls? Is that mold on your floor also spread across your entire sub-flooring? In our opinion, DIY mold cleaning is almost always a bad idea. We have received many a phone call from distressed DIY’ers who had the thought to save money then, only to pay dearly later.
