In a rainbow or the separation of colors by a prism we see the continuous range of spectral colors (the visible spectrum). A spectral color is composed of a single wavelength and can be correlated with wavelength as shown in the chart below (a general guide and not a precise statement about color).
How Much Do Mold Inspections Cost? Mold inspection costs vary widely depending on the size of the property, extent of the mold inspection, number of mold samples, and other factors. We've heard of price quotes as low as $300 and as high as $3,000. While cost is clearly an important factor for most people, we recommend including other factors besides the mold inspection cost when choosing a mold inspector.
1 On average, cleaning up mold can vary from as little as $500 to as much as $5,000 for one room. 2  If a crawlspace or the attic is involved, this can cost an extra $2,000 to $5,000 depending on the size and area of the room that was infected as well as the ease of access to the attic or crawlspace. Depending on the amount of samples that they take, mold tests can run anywhere from $200 to $600. 2  If the company does not offer a free initial inspection, this can cost anywhere from $75 to $200. 3  Most of the time, mold infestation is caused by a moisture problem.
