Mold problem in cold rooms


Mold is often thought of as a seasonal problem, and many homeowners think their mold problems go away when the weather is cold. However, although temperature affects how mold grows, it is a year-round problem.


Mold on indoor surfaces can damage your home and negatively affect your health. It's important to know how and where mold can grow in your home, even during the winter months.


Read on to learn the answers to the 9 most frequently asked winter mold questions.


1. Can mold form in cold weather?

The short answer is yes. Mold needs three things to grow: adequate moisture, adequate nutrient supply, and the right temperature. However, contrary to what many people think, mold does not only form in warm environments.


Different types of mold grow under different conditions, and some molds are more likely to grow during the winter months than others. Each type of mold has minimum and maximum temperature ranges for growth; Many types of fungi thrive in environments between 60 and 80 degrees Fahrenheit. Unfortunately, the right temperature conditions for mold growth are also ideal for our comfort, and we tend to heat or cool our homes to stay within these parameters.


2. What types of mold can occur in winter?

The most common types of winter mold are:

, is a genus of fungi whose species are all common plant pathogens. It thrives in cold temperatures, especially when moisture is present. It typically appears gray or black and tends to be found in moist environments such as bathtubs, shower curtains, and bath mats or basement walls when grown indoors.


The Cladosporium genus includes some of the most common indoor and outdoor mold species. It can survive temperatures as low as 4 degrees Celsius (39.2° Fahrenheit). Species within this genus appear differently, but the species most commonly found indoors are generally brown to blackish brown or greenish gray.


Penicillium species survive in temperatures between 7 and 35 degrees Celsius (44.6 and 95° Fahrenheit), so these molds are often found in all seasons. Like other common indoor molds, it thrives in moist conditions and is often found on damp building materials, carpets, mattresses and upholstered furniture.


3. Does mold die in winter?

Cold weather does not kill mold. Mold Problems are opportunistic in the sense that they begin to spread after waiting for the right conditions.


Extreme temperatures do not kill mold, but can inactivate it. Even when the temperature drops below freezing, mold spores do not die; they simply become dormant and begin to multiply and grow again as soon as the temperature rises.


So controlling the temperature alone won't solve your mold problems. The key to removing mold from your home and preventing it from reoccurring is to control humidity levels and prevent moisture build-up.


4. Why does mold appear on windows in winter?

Autumn and winter months bring rain and dew, and surfaces that collect moisture, such as window panes in our homes, are ideal places for mold to expand and grow.

Moisture collects on and around windows in the winter due to condensation, which forms when warm air hits a cold surface. When the temperature drops during the winter months, the warm air in your home comes into contact with the cold glass of your window panes, accumulating water vapor and causing moisture to accumulate around your windows. That's why moisture and sometimes mold tends to accumulate around windows during the colder months.


5. Do mold allergies go away in winter?

Mold allergies are common and can cause a variety of unpleasant symptoms, including sneezing and runny nose, coughing, itching in the eyes, nose, throat or skin, and watery eyes. Mold can also trigger asthma attacks in asthma patients who are allergic to mold. Many people find that their allergy symptoms decrease when the temperature drops.


Unfortunately, people with mold allergies often experience more symptoms during the winter months, when they are more likely to stay indoors for long periods of time. Mold allergies can be worsened by indoor heat, which can cause mold spores that accumulate in your ducts and other places to spread into the air.


6. How do you prevent mold growth in winter?

What you can do at home to prevent the formation and spread of mold during the winter months: These strategies will also help prevent and cure mold allergies:


Always try to keep the humidity level throughout your home below 50%.

Inspect pipes and fix plumbing leaks as soon as possible to prevent water from pooling.

Use mold-killing cleaners in bathrooms and areas of your kitchen where moisture accumulates.

Avoid having carpets or rugs near windows, sinks, or other areas that tend to get wet.

Check your air ducts and change the filters in your furnace regularly.

Always use a ventilation fan when showering or bathing.

Clean your gutters regularly to prevent moisture from accumulating in collected debris.

Get rid of old recycled materials, newspapers, and upholstery or fabric that has been exposed to moisture.

7. What are the health consequences of mold exposure?

Indoor molds can pose a risk to human health when spores settle and begin to grow on wet or damp surfaces. Molds produce a variety of allergens and irritants that can cause unpleasant or even dangerous symptoms when the spores are inhaled or touched. These symptoms may occur immediately after exposure or, in some cases, may be delayed.


The most common health risks and symptoms of mold exposure include:


Nose irritation and sneezing

eye irritation

skin rashes

throat irritation

breathing problems

asthma attacks

8. Where does mold usually form?

Molds are fungal growths that are a completely natural part of the environment. Mold species can be found almost anywhere moisture and oxygen are present; It can grow in external environments, such as soil or plants, and in dead or decaying matter.


Molds are also often found in wet or damp indoor spaces. The most common places where you can find indoor mold are:


Around leaks in windows, roofs or pipes

Locations where flooding or moisture accumulation occurs

in dust

In paints, wallpaper or drywall

On carpets, fabrics or upholstery

In insulation material

on paper products

In or around indoor plant pots

In some cases, mold can be easy to see and identify. However, it is important to be aware of hidden mold that may not be visible due to its location. If you don't see any visible signs of mold, smell dirt or mildew, have recent water damage to your home, or are experiencing health problems, you can still identify the problem.


9. Is it possible to get rid of winter mold on your own?

It is not possible to get rid of all mold problems in a closed environment. Some spores will always remain in the air or be found in household dust. However, molds that settle on the surface and begin to grow should be dealt with as quickly as possible.


Whether a homeowner or building owner should handle mold cleanup without the help of a professional depends on:

1) size of moldy area (less than 10 square meters)

, 2) go to the area to see the extent of any water damage and see if any contaminated water is found,

3) if you plan to hire a contractor to work on your home,

 4) If you suspect your HVAC system is contaminated with mold and

 5) Health concerns if you have any mold.


If you choose to get rid of winter mold yourself, it is important that you strictly and carefully follow official mold removal guidelines and take every precaution to protect the safety of yourself and others.

Mold needs the right temperature, humidity conditions and nutrient source to grow. Room temperature conditions and organic materials such as paper, cardboard, wood and ceiling tiles are nearly impossible to remove from your home. Therefore, the best way to prevent the spread of mold is to control humidity. Using dehumidifiers and a meter to test humidity levels will help stop moisture from accumulating and prevent mold growth around windows.
