    What Causes Musty Odors in My Home?

    Have you noticed a musty odor in your home? Or a musty smell coming from your attic? Musty odors are characterized by a damp or wet staleness that lingers for long periods of time. Musty odors and mold can cause allergies and health-related issues.

    If you notice a musty odor coming from your attic, there is a good chance the problem is caused by mold.

    In Washington state’s wet and humid climate, you’ll find mostly two types of mold: Black Mold and Green Mold.


    • Black Mold

      Appears mostly in dark, damp, warm, and humid areas of your home. If your home has a source of moisture, black mold can grow. It’s obvious to spot by the color, but prolonged exposure can cause allergic reactions or health issues. Some people will suffer frequent headaches, rashes, fever, sneezing, coughing, or even chronic fatigue.

    • Green Mold

      Appearing in gray, green, brown, yellow, or gray in color, most homeowners will find green mold growing on and inside walls, carpets, and insulation. Green mold prefers wet places, regardless if it’s warm or cool.

    How Attic Projects Gets Rid Of Mold

    Wherever there’s excess moisture, there can be mold spores. Mold spores float in the air, attaching to household dust.

    Attic Projects specializes in finding the source of the mold and removing it from your attic. Removing mold is a task homeowners should never do on their own, as mold can be extremely toxic. Without the right tools and cleaning sprays, you may not fully eliminate the problem and instead push mold spores and particles into the air of your home.

    If there is mold in your attic, that means water is somewhere in your attic. When Attic Projects comes to remove mold, they will dry out your attic, decontaminate and sanitize your attic, and find the source of the mold and eliminate those pesky musty odors for good.

    Cleaning Up After Rodent Infestations

    Attic animal infestations are messy and dangerous. Rodents and other animals carry harmful germs and bacteria that could make everyone in the home very ill. Additionally, animals in the attic quickly become a nuisance by chewing holes through just about anything, including electrical wires, insulation, and walls.

    The waste left over from animal infestations shouldn’t be removed by the homeowner. Instead, attic sanitation professionals like Attic Projects should be called in to clean up after an animal infestation. The professionals will decontaminate your attic using germicidal sprays, killing any bacteria and disease-causing pathogens.

    Attic sanitation professionals will also remove any animal waste in the attic and close up the entry points to prevent rodents and other animals from returning.

    What’s Included in Our Service:

    If your attic has an animal infestation or mold, Attic Projects highly recommends you sanitize the attic. Attic sanitation will remove bacteria, mold growth and spores, pest droppings, and any germs from your attic. Attic sanitation should only be completed by a professional.


    • Before your attic is sanitized, attic sanitation professionals will come and inspect the entire area looking for pest droppings, mold growth, and any other health hazards. 
    • Next, they will inspect electrical and HVAC or any plumbing located in the attic. 
    • All insulation material will be removed to provide a full view for the inspection.
    • Attic Project professionals will look for the source of the issues in your attic. They will identify where pests are coming in and close up entry points to ensure pests cannot get back inside your home.
    • In the case of mold, the professionals will look for the source of water. 
    • After, technicians will use disinfectants to kill germs, fungus, bacteria, and mildew.

    We live in an older home near a large park area. Since buying our home, we’ve had to deal with the occasional rat. These guys came out and sealed my entire attic space – vs setting a few traps. Then vacuumed out the entire space that had nearly 100 years of debris – including from our new roof and insulated the entire house. Love the 5 year warranty against the rats and we already notice how much warmer the house is. The did a great job keeping area clean and protecting floors, walls while working. Highly recommend.


    It’s a stressful situation when you find black mold in your home. The guys at Attic Projects were professional, polite and respectfully clean. They finished the job in a timely manner and went the extra mile to make sure I was satisfied with their work. Once the job was completed we instantly noticed a difference in our home’s humidity- going from 70% to the optimal 50%. I’d highly recommend these guys. Jordan, your customer service was top notch, thank you for making this a stress free experience.


    Attic Projects was so incredibly thorough and detailed with their description of how and why they were going to do each step, I knew I could trust them. These guys get it!! Total professionals, hard workers and they invited me to poke my head up in the attic during and after the job was complete. My in-laws received before and after pics and received a 5-year warranty on rodent proofing This was a big job and these guys absolutely killed it. I’d recommend them to anyone with similar issues. Thanks Attic Projects!!

    Frequently Asked Questions:

    Why should I hire a professional to sanitize and decontaminate my attic?

    Hiring professionals to sanitize and decontaminate your attic lowers your exposure to harmful toxins, such as mold and bacteria left by rodents. When you hire a professional, they will arrive with the high-grade equipment and chemicals necessary to remove any bacteria, germs, or mold thoroughly.

    Can contaminants in the attic spread throughout my home?

    When you have contaminants in your attics, such as mold, the spores can attach to household dust and spread throughout your home. Once mold spores are floating throughout your home, you and your family could breathe these in and cause illness.

    My home has a musty odor… Could this be a sign of mold in my attic?
