The short answer
Find the Moisture Source
A musty smell means moisture is present somewhere. Check for visible leaks under sinks, around windows, or near the roof. Look for water stains on ceilings or walls, and feel for damp spots on carpets or drywall. Even a slow leak can keep materials wet enough to cause a smell.
If you cannot find the source, a water damage inspection can help. Pros use moisture meters and thermal cameras to locate hidden water. They can also check for condensation from air conditioning or plumbing issues. Finding the source is the first step to fixing the problem.
- Look under sinks and around toilets
- Check ceiling tiles for brown stains
- Feel walls and floors for dampness
- Inspect window seals and frames
- Listen for dripping sounds in walls
- Check the HVAC system for condensation
Dry Out the Area
Once you find the moisture, you need to dry the affected materials. Open windows and use fans to increase airflow. Dehumidifiers help pull moisture from the air and speed up drying. If the area is large, structural drying and dehumidification services can handle the job.
Drying can take days, depending on how much water is absorbed. Carpets, drywall, and insulation may need to be removed if they stay wet too long. The pros often use specialized equipment to dry behind walls and under floors. This prevents mold from growing and removes the musty odor.
- Use fans to circulate air
- Run a dehumidifier in the affected room
- Remove wet carpets and padding
- Cut out soaked drywall if needed
- Set up air movers to dry hidden spaces
Address High Humidity
High humidity can make an office feel musty even without a leak. Bathrooms, break rooms, and areas with poor ventilation often trap moisture. Humid air condenses on cold surfaces, like windows or pipes, creating damp spots. Keeping indoor humidity below 50 percent helps prevent musty smells.
Use exhaust fans in bathrooms and kitchens, and keep the HVAC system running to circulate air. If humidity stays high, a dehumidifier can help. You may need to adjust your humidity controls seasonally, especially where weather varies. Monitoring humidity with a simple hygrometer can alert you to problems early.
Clean Mold and Mildew
If mold has already started, cleaning is necessary. Small patches on hard surfaces can be wiped with a mild detergent and water. Wear gloves and a mask to avoid breathing in spores. If the mold covers a large area, or if you have health concerns, see a doctor if you feel unwell and consider hiring a mold professional.
Cleaning alone may not stop the smell if mold is inside walls or under flooring. The pros can remove contaminated materials and treat the area with antimicrobial solutions. They also ensure the space is dry before you repaint or replace flooring. This helps prevent mold from returning.
Prevent Future Mustiness
After fixing the moisture issue, take steps to keep the office dry. Fix leaks promptly, keep gutters clear, and ensure the roof is in good condition. Maintain the HVAC system and change filters regularly. Also, encourage good airflow by keeping doors open and using fans in stuffy areas.
Regular inspections can catch problems early. Check for water stains or musty odors every few months. If you live in Layton, keep a list of emergency contacts, like a plumber or water damage pro, handy. Acting quickly when you notice a smell can save you from bigger repairs later.
