The short answer
Where Moisture Hides
A musty smell is almost always a sign of dampness. Check the usual spots first: under the sink, around the toilet, near the water heater, and along baseboards. Look for water stains on the ceiling or walls, which can point to a slow roof leak or a pipe that has been seeping for a while.
Also check your studio's ventilation. Bathrooms and kitchens without exhaust fans trap humidity from showers and cooking. Even a small dehumidifier can help, but it will not fix the problem if there is an active leak. Finding the source is the first step.
- Look for discoloration on drywall or ceiling tiles
- Feel walls and floors for dampness
- Check under rugs and mats
- Inspect window frames and doors for condensation
- Smell around outlets and light fixtures
- Look behind furniture that sits against exterior walls
Find the Leak Source
If you suspect a leak, you can do a few checks yourself. Turn off the water supply to your studio and see if the water meter still moves, which would indicate a hidden leak. Check the water heater for rust or moisture at the base. Look at the roof from inside, especially near skylights or vents.
For hidden leaks, a professional leak detection service can use specialized tools to locate the exact spot without tearing into walls. If you live in Layton, keep the location of your main shutoff valve written down so you can act fast if a pipe bursts.
Dry the Space Thoroughly
Once you stop the water source, the drying process begins. Open windows if the outdoor air is drier than indoors. Use fans to move air across wet surfaces. A dehumidifier pulls moisture from the air, which speeds up drying and reduces the musty odor.
For serious water damage, structural drying and dehumidification may be needed. This involves industrial equipment that can dry out walls, floors, and other building materials that hold moisture. This step is important because damp materials can lead to mold growth if left untreated.
Remove Damp Materials
Some materials cannot be saved after water damage. Porous items like drywall, insulation, and carpet padding absorb water and can harbor mold. You may need to remove and replace these. Water-damaged flooring, such as laminate or hardwood, often warps and may need removal.
If you have a flooded basement or a burst pipe, the cleanup can be extensive. Emergency water extraction removes standing water, but the drying and removal of damaged materials is a separate process. Do not try to dry out materials that have been soaked with sewage or floodwater, as they can be hazardous.
Prevent Future Mustiness
After your studio is dry, take steps to keep it from happening again. Fix any leaks promptly, improve ventilation, and consider a dehumidifier in humid months. Check roof flashing and seal around windows and doors. Keep an eye on areas that have been wet before, as they may be more prone to problems.
Regularly inspect your studio for early signs of moisture, such as staining or a faint musty smell. If you notice something, address it quickly. For ongoing moisture issues, a moisture mapping service can identify problem areas in your home.

Can I just paint over a musty wall?
Painting over a damp or moldy wall will not solve the problem. The moisture and mold will eventually bleed through. You need to find and fix the moisture source, dry the wall, and remove any mold before repainting.
How long does it take for mold to grow after water damage?
Mold can start growing within 24 to 48 hours in the right conditions. That is why it is important to dry out the area quickly. If you have had standing water, act fast to remove it and start the drying process.
Should I call a professional for a musty smell?
If you cannot find the source of the moisture, or if the area is large, it is wise to call a professional. They can locate hidden leaks and dry the structure thoroughly. For small, visible leaks, you may be able to handle it yourself.
