Humidity and Mold in a Batumi Apartment: What to Check Before Renovating

Dark spots have appeared around the windows, the paint is blistering, and the room smells damp. It is tempting to strip the old finish and repaint the walls straight away. But if the cause remains, the stains can return after renovation.

Before buying materials for your Batumi apartment, inspect the windows, exterior walls, pipes, and ventilation. You need to understand where the moisture is coming from and what needs fixing before the finishing work begins.

Where the damp comes from

Water can enter through defects in the facade or the joints around windows, or escape from leaking pipes. Another source is condensation: moisture in the air settles on a cold surface. Wet construction work can also leave moisture in walls and floors.

Each situation calls for different work. Fixing a leak, improving ventilation, and drying the surface beneath a finish are separate tasks. Moisture-resistant finishes will not solve these problems on their own. These causes and preventive measures are covered in the EPA guide to moisture control in buildings.

Before a specialist visits, observe what happens in the apartment. Do damp patches appear after rain, a shower, cooking, or a long absence? Do they stay in one place or appear in several rooms? Write this down and take dated photographs. A single dried-out stain rarely tells the whole story.

Where to start your inspection

Check the surfaces around the windows and the joints between the frames and walls. Look for droplets, dark patches, and water marks after rain. A specialist will need to distinguish between a leak and condensation.

Next, inspect the exterior walls, corners, and ceiling. Damp patches, stains, and peeling paint can help identify where to look for water ingress. In the kitchen and bathroom, look under the sink and check accessible pipe connections.

Do not overlook the areas behind furniture. Stains and smells there are easy to miss during routine cleaning. If there is a smell but no visible source, hidden areas may need inspection. Avoid opening up suspect finishes yourself, as this can spread mold spores. See the EPA guidance for homeowners.

What a hygrometer can tell you

A household hygrometer measures relative humidity. Record readings at different times, especially after showering, cooking, and airing the room. This will help you see when humidity rises and how quickly it falls.

The EPA recommends keeping it below 60% where possible, ideally between 30−50%. These figures help you monitor indoor conditions, but they do not explain the cause of a particular stain. See the [EPA mold prevention guidance.

If readings stay high, check the ventilation. Can fresh air enter? Where does moist air escape? Are any vents blocked? Discuss this before installing new doors and furniture.

Leaving a window open all the time will not necessarily help. When the outdoor air is warm and humid, airing the apartment may not be enough. In that case, discuss dehumidification and choose equipment suited to the apartment’s conditions. The EPA explains when ventilation and dehumidification are needed.

If mold is already present

Do not paint over the patches or conceal them behind panels. The moisture source needs to be addressed, the mold removed, and the surface dried. Affected porous materials sometimes need replacing.

Anti-mold paint will not fix a leak. Apply a new finish only after cleaning and drying. If water has damaged a large area or mold is hidden inside a wall, contact a specialist experienced in this work. The EPA guide outlines the steps to take.

What to discuss with your contractor before renovation

Ask which work will address the cause of the damp, and have it listed separately from restoring the finishes in the estimate. Clarify what evidence supports the diagnosis and whether further checks are needed.

Before approving the estimate, discuss a few more details:

• Which materials can be kept and which need replacing.
• How the contractor will check that the walls and floor are dry enough for the chosen finishes.
• How ventilation will work after renovation and whether a dehumidifier will be needed.
• Who will check the apartment if you are away for an extended period.

These answers make it easier to compare contractors' proposals. You will be able to see what the price includes and which problems need resolving before the walls are painted or floor coverings installed.
