We provide mold inspection and remediation services. Mold is one of nature’s chief decomposition mechanisms, and more than 1,000 species of mold can be found in the United States alone. If left untreated, mold will decay organic matter, such as cotton, leather, paper, drywall, and structural wood. Molds can grow on virtually any substance or material, as long as moisture or water, oxygen, and an organic food source are present. They reproduce by creating tiny spores that are too small to see with a naked eye, and those spores continually float through the indoor and outdoor air using air currents as transport. Mold spores are a major concern for professional remediators, because they are so small that they can be anywhere there is air, including under carpet, inside wall cavities, under kitchen cabinets, virtually everywhere.

Mold Remediation FAQs

What Is Mold?

Mold is a fungus that can be found anywhere there’s moisture — from basements to bathrooms to kitchens in Costa Mesa. While some may be in plain sight, mold can be in obscure places and require professional mold testing and inspection services to be detected. It causes musty odors that you might smell in the bathroom or basement. Different mold types can have various colors, including black, green, white, or red. It may look like spots or thin layers on your ceiling, walls, or floors.

Some common sources of moisture include leaky pipes, overflowing sinks, and toilets, which require a professional mold inspecter to fix. Costa Mesa mold doesn’t just affect your health; it damages materials such as wood, drywall, and carpeting by destroying their surfaces and making them look old and discolored.

Mold testing and inspection services in Costa Mesa tests your home or commercial property for all types of mold. There are several types that have harmful pathogens such as bacteria and viruses that can pose a health hazard.

How Do I Know If I Have Black Mold?

Black mold is a fungus that grows on materials made from organic matter. It is usually found in humid areas with poor ventilation, like bathrooms and basements. To identify it in its early stages, you may need mold testing and inspection services in Costa Mesa. Here are a few signs of mold:

It has a distinct, musty smell

The first sign of black mold is a musty odor that comes from the spores of the fungus. If you notice a musty smell in your home, check all of the rooms where there are carpets or rugs. If you see any discoloration on these surfaces, you may have black mold in your home.

Another way to check for black mold is by using ultraviolet light (UV light), which is what mold testing and inspection services in Costa Mesa utilize. If the mold is blue under UV light, it’s black mold.

It grows in patches that are often fuzzy

Black mold often grows in fuzzy patches, which can be hard to locate without professional mold testing and inspection services. The fuzziness is caused by tiny black spores that float through the air. When these spores land on a damp surface, they start to grow into long, narrow strands of mold before producing new spores.

It is black or dark greenish-black

Black mold starts as a white or gray powdery substance that resembles dust you might find on your furniture or the top of your bookshelf. As it grows, it turns black and can produce toxic spores that may cause allergic reactions, especially in people with respiratory conditions. You may be able to see the black mold growing on walls, floors, and ceilings in your home or office building.

It is slimy and wet

Black mold is slimy and wet during its mature stage, making it easy to identify. It is often confused with its less harmful relative, green or brownish-black mildew. Black mold in Costa Mesa homes has no smell until it starts to decay after being exposed to oxygen for several days. When the spores break down, they produce toxic gasses that cause respiratory problems when inhaled by humans and animals alike.

It is best to contact a company offering mold testing and inspection services in Costa Mesa to identify black mold accurately. If you are unsure whether it is black mold, it is best to contact a professional mold testing service for your safety.

What Is The Mold Remediation Process?

The mold remediation process is a multi-step procedure that can be completed in one day or over several weeks, depending on the extent of the problem.

Identifying the problem

The first step in the mold remediation process is to identify or test for the source of the mold infestation. The mold inspector will use specialized equipment to detect any signs of mold growth.

Removing the mold

A mold inspector uses commercial products to perform a mold inspection and mold removal from hard surfaces such as walls, floors, and ceilings. These products contain chemicals that kill the mold spores and break down the mycelium (the vegetative body of a fungus). They also contain surfactants that help loosen and lift off loose mold so it can be vacuumed or wiped away with a cloth or sponge. Proper mold inspection and removing mold from hard surfaces are critical because even small amounts of airborne spores can trigger allergic reactions.

Drying out the space

After removing all visible mold growth, keeping the affected area dry throughout the remainder of the project is crucial. Moisture can cause new areas of mold growth if it isn’t thoroughly removed, so the mold inspector will not let water sit on walls or floors for long periods during this process.

Repairing damage

Any repairs will depend on what type of damage occurred due to the presence of mold. If moisture has seeped into drywall due to leaking pipes or poor ventilation, you may need to replace this material with new drywall and paint over it.

Preventing future mold growth

To prevent recurring mold growth, our technician will seal off all areas where water could get into your home or business and fix any leaks that allow water in. They will also recommend preventive mold growth measures, including getting a dehumidifier and better ventilation.

Can I Clean Up Mold Myself?

Yes, you can. There are many ways to clean up mold; however, it is crucial not to use harsh chemicals or scrubbing pads, as this will only worsen the situation. Instead, try these safe and effective methods:


Mix one part ammonia with two parts water and wipe down any surfaces that have been affected by mold growth. Be sure that all materials are thoroughly dry before using them again so as not to reinfect them with spores.

White vinegar solution

White vinegar is an effective mold killer that won’t damage your belongings. Mix one part white vinegar with three parts water in a spray bottle and apply it directly to the moldy area. Let it sit for five minutes before wiping it away with a sponge or cloth. You can also use this solution on hard surfaces such as tile or grout by pouring it directly onto the spot and letting it sit for several hours or overnight before scrubbing it clean with water and soap.

Borax solution

Borax is another natural substance that kills mold while leaving your furniture and floors intact. It works best when used on porous surfaces like wood, brick, or concrete — not on fabrics or walls. Sprinkle borax powder over the area where you see mold growing, then pour boiling water over it until most of the powder has dissolved (don’t worry about dissolving all of it). Let it sit for 10 minutes before scrubbing clean with warm water. These solutions can temporarily fix small areas; you will need a mold inspector’s help for large-scale mold eradication.

Although these are excellent home remedies for mold growth, it is still best to contact a professional Costa Mesa mold specialist to eradicate mold completely. Our mold inspection technicians use proven mold remediation methods and techniques to prevent mold problems from recurring.
