Getting Rid of Basement Odors

Thursday, July 22nd, 2010

In our previous article, we discussed about the different causes of basement odors and where they originate from. But how do we get rid of these musty odors to improve our basements in the home? Let us look at some of the effective ways of dealing with these unpleasant and uncomfortable odors in the basement.

clip_image002

1. Cleaning the basement: Cleaning your basement will get rid of most of the musty odors, mold and mildew, dampness and humidity existing in the basement. Choose a sunny day to remove all the furniture and carpets in order to sun-dry them and also deep-clean the carpets. Sweep and dust all around the basement to remove dust that is the primary cause for allergies and other respiratory problems. It is recommended to use a disinfectant to clean the walls and floors, so as to get rid of the musty odor due to mold and mildew growth that are usually found under carpets, behind panels and behind perimeter walls. Throw away all the unnecessary stuff from your basement as they are favorable to the growth of molds and, in addition, you can create space in the basement. Arrange clothes, books and furniture in a neat way by keeping all clothes in the wardrobe, arranging books in stacks and minimizing the furniture in the basement.

2. Waterproofing:
Cracks or leakages in the walls are usually caused due to dampness. The dampness could be either due to unfavorable climatic conditions, improper drainage system and excessive humidity. Cracked walls should not be left as they are, and should be either sealed or patched as soon as they are identified. Leaving a cracked wall unattended could worsen the situation by widening and spreading all over the wall. Dehumidification is essential for leaking walls, since it helps in drying the wall. These walls can be cleaned with trisodium phosphate, a hard surface cleaner. Once the walls dry, seal them with a latex concrete sealer to avoid further leakage and musty odor.

3. Dehumidification:
Humidity is another primary cause for smelly basements. A dehumidifier can help in controlling the humidity in your basement. Attaching a hose to the dehumidifier will get rid of the excess moist air in the basement, leaving no space for the growth of molds that lead to the musty smell. It is also essential to keep in mind the type of dehumidifier you choose for your basement and should be based on the efficiency and size of your basement.

4. Ventilation: This is undoubtedly one of the most important factors to consider when getting rid of basement odors. On a fine sunny day, just open all the windows in your basement and switch on your exhaust fans to allow circulation of fresh air within the basement from outside. Cross-ventilation is also very important in removing humidity and stagnant air that gets accumulated in the basement.

5. Drainage system:
Ensure that you install both a proper interior and exterior basement drainage system to prevent condensation that can lead to dampness. Wrap pipe insulation around the basement pipes to avoid condensation from building up on them. Leaking basement walls can trap water and increase humidity in the basement. Ensure that the ground slopes and downspouts are extended around six feet away from the house. You can also read our blog article on basement drainage systems for more information at http://blog.keystonebasementsystems.com/?p=980.

Apparently, there are also some home remedies that could be useful to get rid of the musty odors in your basement too.

• Baking soda is effective for neutralizing odors and absorbs moisture and so you can either leave it open in a container or sprinkle a little on your smelly carpet and later vacuum it.
• Vinegar is a household product that helps in neutralizing odors, including those left behind by pet accidents and skunk sprays.
• Citrus fruits like lemons and oranges leave a pleasant smell behind and can be used as air fresheners.
• Charcoal and cat litter help in absorbing moisture.

What is Dew Point?

Thursday, July 1st, 2010

On a cold winter morning or evening, you must have felt tiny droplets of water in the atmosphere or for that matter seen water droplets in the air in the form of fog on cold beverage containers during the hot season. But have you ever wondered what lies behind this natural phenomenon? The answer is dew point, which we will discuss in detail in this article.

dew-pointDew point, or otherwise better known as dew point temperature, is the temperature at which the liquid and gaseous phases of a material present in a gas, such as water in air, are in equilibrium at a given gas pressure. In the case of water, the temperature at which both evaporation and condensation of water take place are the same. An interesting point to note about dew point is that it is related with evaporation, condensation and relative humidity.

How Does Temperature Affect Dew Point?

It is a known fact that warmer air can hold or suspend more water vapor in the air than cold air. When the air cools down, it naturally loses its ability to hold moisture in the air. Dew point temperature is also known as the saturation temperature of water vapor in the air, the reason being that when the temperature is lowered from the saturation temperature, water vapor condenses faster than it evaporates. On the other hand, when the temperature is increased from the saturation temperature, water vapor evaporates faster than it condenses. At the saturation temperature, the evaporation and condensation rates of water vapor in the atmosphere are at equilibrium.

Dew Point vs. Humidity

As mentioned in our previous article, relative humidity is the amount of moisture or water vapor that is suspended in the atmosphere. Dew point and humidity have been found to be related and are dependent on the amount of water vapor in the air and the total amount of water vapor that the air can hold at a given temperature. This is the main reason why you see tiny droplets of water on cold surfaces during hot weather conditions.

When relative humidity increases, the dew point temperature is closer to the current air temperature and when relative humidity decreases, the dew point temperature is at par with the current air temperature. When dew point temperature and real temperature are the same, relative humidity is 100%. At this point of time, fog, mist, dew and clouds start forming due to condensation and this means that the air is holding 100% moisture.

Basic Points to Know about Dew Point

• Dew point temperature can never be higher than the current temperature.
• When the temperature is the same as the dew point temperature and then starts falling, the dew point temperature must simultaneous decrease.
• The amount of moisture in the air increases with increase in the dew point temperature.
• Relative humidity of around 100% is an indication of dew, frost, fog and rain.
• Regions around the Equator experience high dew points, whereas the desert and polar regions experience low dew points.

Applications

• Heat transfer by convection
• Combustion of fossil fuels and combustion engineering
• Drying of paper, cardboard, plastics, wood, tobacco, leather, printed goods, textiles and grain
• Energy efficiency in chemical manufacturing processes
• Prevention of corrosion in iron, steel and other metals

What is Condensation?

Thursday, June 24th, 2010

Condensation is the conversion of water from its gaseous state into its liquid state. There is always some amount of moisture present in the air. During cold weather conditions, the moisture present in the air condenses into tiny droplets of water. In fact, the air that you breathe out can be seen on a cold winter morning. Condensation can also occur on those hot, humid summer days where you would need an air conditioner to cool your home. This may result in hazy windows due to the air conditioning.

clip_image0021Household activities such as cooking, washing and drying clothes are responsible for the excess moisture present in the air within your home. An average family creates around 20 pints of water vapor per day. This can be usually seen in the form of fog, mist, dew or frost in the atmosphere and plays a significant role in the formation of clouds, rain and snow.

Condensation is a result of the fall in temperature of vapor even below its saturation temperature. When warm air rises in the atmosphere and cools down, it loses its ability to hold the water vapor in the air and hence the excess water vapor condenses to form cloud droplets.

What does condensation have to do with basements? Well, it has quite a lot to do with basements. The moisture that forms as a result of condensation can cause rotting window frames, peeling wallpaper and mold on walls, carpets or clothes. This phenomenon occurs where there is no adequate air circulation. You may have noticed mold on your windows, walls, ceilings and furniture a couple of times, especially during the winter season. This also comes along with stale air that gets accumulated within the basement due to lack of ventilation. All these factors lead to aggravation of illnesses such as asthma and bronchitis.

What is the difference between condensation and dampness?

Dampness can be a result of condensation. As mentioned earlier, condensation occurs during cold climatic conditions when the water vapor is surrounded by cold temperature and the moisture content of the air is high. This leads to the growth of mold and mildew which may due to lack of air circulation and insulation. Dampness can also be caused due to other reasons such as leaking drainage pipes, wastes or overflows, cracked walls and ceilings, leakages from the roof where tiles are missing during rains and defective damp course or no damp course.

Condensation in the basement can be caused by the following reasons:

(1) Lack of ventilation, especially during the summers
(2) Lack of insulation, especially during the winters
(3) Inadequate heating in the basement

How to Reduce Condensation or Dampness in the Basement

(1) Allow moisture to move out of your home when cooking, washing or drying clothes and heating by closing doors to avoid circulation of moisture and opening windows to let out the moisture.

(2) Make sure that you ventilate your home to remove moisture by opening windows, using exhaust fans in the kitchen and bathroom to let out the damp air after frying or taking a hot shower, installing air vents wherever possible, cutting breather holes in cupboards and wardrobes and installing ventilators for windows.

(3) Insulate your basement by air sealing, installing insulators in your walls, dehumidifiers, which will keep your rooms warm and simultaneously prevent the entry of moisture and hence avoid dampness. Get effective ways of insulating your basement from our blog article, http://blog.keystonebasementsystems.com/?p=923.

(4) In order to remove mold and mildew from walls, use a fungicide. Clothes and carpets affected by mold can be dry cleaned and shampooed, respectively. Mold and mildew creates a high risk of respiratory problems and gets worse if disturbed by brushing or vacuum cleaning.

(5) Get rid of any kind of moisture immediately by wiping any surface moisture to avoid room for any damage.

(6) Fungicidal paints for the walls will also help in preventing growth of mold and mildew.

So next time you think of basement condensation, you know exactly what to do!

The Importance of Basement Dehumidification

Thursday, June 10th, 2010

Have you ever thought of the positive effects of ventilating or dehumidifying your basement? Well, in order to understand these factors, let us first look at the causes of poor ventilation in your basement. A wet or damp basement could be a result of wall cracks and pipe leakages and weather conditions such as cold winters and floods. This leads to dampness along with stale air circulating within the basement which creates a favorable environment for the growth of mold and mildew. In contrast, during warm weather conditions, the humidity tends to be on the higher side and lack of ventilation in the basement leads to recurrence of stagnant air, bad odor and growth of mold.

clip_image002_1

How can this be avoided and what does it have to do with basement dehumidification? Apart from water damage dehumidification and mold remediation, basement dehumidifiers have always been considered as an alternative measure for moisture control, air exchange and ventilation, especially in areas like basements and crawl spaces. On the other hand, there have been issues such as the cost factor, daily maintenance and efficiency between traditional and modern humidifiers.

The benefits of having a high-quality, energy-efficient dehumidifier in your basement will definitely make up for the cost of buying and maintaining it in the long run. These benefits include:

1. Mold: As mentioned earlier, installing a dehumidifier in your home reduces the chances of mold damage, since the cleanup and replacement costs come at very high rates. In fact, many insurance policies do not cover mold-related expenses which leave us with the only option of trying to prevent the damage.

2. Health: The constant circulation of stale air inside the basement obviously affects the immune system, targeting the respiratory functions by inhaling allergens, bacteria, fungi and dust. This leads to colds, asthmas, flus, allergies and other respiratory problems. The installation of a dehumidifier reduces this risk and recycles the stale air circulating in the basement by condensation.

3. Space: Due to the common problems in the basement such as lack of ventilation, dampness and poor air circulation leading to an uncomfortable environment, these areas are not fully utilized as compared to other areas such as the living room. Dehumidifiers will help control and maintain temperature levels in basements at all times, providing cozy and comfortable surroundings.

4. Energy: The air molecules of damp air caused by the presence of moisture in the surroundings are heavier than the normal air molecules and therefore affect air circulation. This in turn leads to excessive or improper utilization of heating and cooling systems which require more energy.

5. Selling Opportunities: Homes with maximum living space have been found to be more attractive to potential buyers. Hence, basements that are well-finished, furnished and comfortable can be made to good use in various ways.

With cutting-edge technology and design at their best in the current scenario, there are energy-efficient dehumidifiers available at reasonable rates. These devices come along with considerable warranties and have improved air quality capable of getting rid of hassles like moisture, mold and condensation.

It is preferable to install basement dehumidifiers in an enclosed area for better efficiency. Installing exhaust fans in the bathrooms and ceiling fans in the basement will help in proper air circulation for sufficient ventilation. Basement dehumidifiers work in a simple way by drawing water vapor from the air and collecting it in a holding tank by condensation and then releasing the water through a drain pipe. They can be installed permanently with the help of a qualified professional or are portable for the user’s convenience to carry it wherever possible.

There are also various types of dehumidifiers. To learn more about Humidex and other dehumidifiers, visit http://blog.keystonebasementsystems.com/?m=200909.

CONCRETE : Popular Building Material

Friday, August 14th, 2009

Concrete is widely used in the construction industry and is a mixture of Portland cement, sand, gravel and water. The Portland cement is composed of Limestone, Silica, Alumina and Iron oxides. The properties of cement vary depending upon the relative amount of these compounds. Major types of concrete include, Self-compacting concrete, Pump concrete, Sprayed concrete, Normal concrete, Special concrete, Mortar, Chipping concrete, Reinforced concrete and Tremmie concrete.

Concrete is used more than any other man-made materials in the world. USA ranks among the top three cement manufacturers of the world. A sizeable section of the labor force is associated to this industry. Statistics reveal that there are 39 cement companies operating 118 cement plants across 38 states with annual shipments valued at around $8.6 billion.

Why should concrete be used as a building material? The main reason lies in its properties. Be it the production of raw materials or demolition of old structures, the eco-friendly property of concrete is what makes it the most obvious choice for sustainable home construction. The ingredients of concrete are abundant in supply and can be restored to their natural state, thus making it a reliable and versatile product for centuries.

Few of the basic reasons why concrete is used as a building material:-

concrete_pour1. Thermal Mass: Homes constructed with concrete floors, foundations and walls have high energy efficiency as the thermal mass ability of concrete aids the easy absorption and retention of heat. This means that homeowners staying in concrete built homes substantially reduce their cooling and heating bills by installing smaller capacity HVAC equipments.

2. Durability: Concrete forms long-lasting and durable fire resistant, rust-resistant and decay resistant structures, which sometimes doubles or even triples their life span in comparison to other building materials.

3. Storm Water Retaining Capacity: Concrete has a sponge-like void network that facilitates the easy passage of water. When utilized for sidewalks, driveways and other pavements, including parking lots, pervious concrete helps replenish local water supplies.

4. Minimum Amount of Waste: Concrete reduces the amount of waste materials in the environment as the requisite proportion can be readily made and directly used onsite for construction purposes. Any residual concrete is recycled by crushing it along with the aggregates for new concrete pavements, as a road base or backfill.

dry-concrete-blocks5. Reflectivity:  Light colored concrete roofs and pavements reflect more solar radiation, absorbing less heat and reducing the demand for Air Conditioning systems during summer.

6. Resource Efficiency: Concrete can also be prepared without its chief raw material, which is limestone. It can also be made using slag cement, silica fumes, fly ash and even byproducts from manufacturing facilities, steel mills and power plants.

7. Strong Weather Resistant: The structural performance of building materials has often found to be inconsistent to lab tested ones. Though it isn’t feasible to avoid losses and destruction, the damage could mitigate through durable building materials.Precast concrete design resists tornadoes and hurricanes effectively. Also, the components don’t ignite during the lightning storm, nor do they permit the spread of fire.

Any decision made during the design and construction stages of the building affects the performance and cost for decades. Designers and building owners have now recognized the fact that enhancing the safety of life could enhance the peace of mind of the tenant and lower the operating costs. It is also worth mentioning here that the life safety and economic benefits of concrete make it more desirable, causing an increase in property value, higher net income and better tenant retention.
