Protecting the window openings of a house is probably one of the most important steps a person can take to protect their family and belongings. When a hurricane hits, high winds and pounding rains are the result. High winds can cause objects such as roof tiles, branches, garbage cans and so on to become projectiles. When this happens, the outer envelope – the separation between the interior and the exterior environments of a building is at risk.
A lawn that’s properly cared for and healthy will resist weeds and other pest problems. Following the best management practices (BMPs) in this publication should help keep your lawn in good condition.
Good performance of the HVAC systems depends on eliminating leaks in the plenum and ducting system and reducing friction within the ducts themselves. This 3-part video shows how to accomplish these goals, which also reduce attic air infiltration into the system.
The buoyant foundations, senior-design project at LSU has focused a spotlight on this technique. Buoyant foundations are not a legal alternative to elevation in flood hazard areas, and specifically violate the flood and wind anchoring requirements of the buidling code and/or flood ordinance. Homeowners should not pin their hopes on adopting this technique for building, rebuilding or restoring homes.
Extensive damage from Hurricanes Katrina, Rita, Gustav, and Ike has caused many homeowners to build at higher elevations above ground, or to raise their existing homes to safer heights. Many people have, or will, turn to elevators, platform lifts or other mechanical systems as their primary means of accessing the elevated floor.
Experience has shown in inland areas floods damage areas of buildings not elevated above the flood level and destroy contents of those areas. In coastal areas, wave action causes even more damage. The NFIP requires participating communities to adopt a floodplain management ordinance that specifies minimum requirements for reducing flood losses.

There are four distinct components of establishing turfgrass: clearing and grading to provide the desired contours and good surface drainage, soil preparation, planting, and watering and maintenance.
Loading equipment onto a truck or trailer usually requires the use of loading ramps. There are some safety issues involved in using ramps.
Because garage doors are so big, usually the single biggest opening of a house, and because most old doors are so weak, the survival of a house’s garage door is very important to the survival of the house. Failure of the garage door allows the full fury of the hurricane to act on interior walls, doors, ceiling or roof that form the barriers between the inside of the garage and the rest of the house.
Central HVAC equipment distributes the air through out the house by a system called “duct work.” When this system is properly designed, air distribution is even and a uniform temperature is maintained. Proper duct work design can allow for the correct sizing of systems, thus increasing savings.
Whether building a new roof or repairing an existing roof in south Louisiana, there are steps you can take to improve your roof's resistance to hurricane winds and driving rain. Here are the essentials for selecting and installing a roof and roofing components.
One sure vestige of a hurricane or bad blow is a large, dead area of the lawn. It usually is located near curbside, or anwhere yard debris is piled up for many days. Some spots can be avoided by careful debris management; others are inevitable and will require restoration.
The load bearing capacity of Louisiana soils varies widely. It is important to know the soil type in the area that you plan to build. Often you can determine if you want to select a certain location for your new home or look further by knowing as much as you can about the area. It is wise to know the flood zone, availability of utilities, and believe it or not the soil type.

Cleaning up wood debris after a hurricane or other severe wind storm can inadvertently spread one of Louisiana’s most destructive pests – the Formosan subterranean termite. The highest concentrations of this termite in the continental United States are in Lake Charles and New Orleans, cities flooded following Hurricanes Rita and Katrina.
A great deal of moisture can move from the ground into and through a foundation and floor system, which can lead to decay, mold under flooring and high indoor humidity. To prevent these problems, keep rainwater away from the foundation with a 5% slope (6 inches/10 feet) of the grade around the house, prevent materials from absorbing water, drain groundwater with underground drainage before it gets to the foundation and allow the moisture in a foundation to escape.
In a hot-humid climate, moisture flows from outside to inside most of the year. In a mixed-humid climate, moisture flow changes direction in cooling and heating seasons. Using the proper wall assembly in your home is important for controlling moisture.
A radiant barrier under the roof decking (foil side down) can block 95% of the roof’s radiant heat. This is most beneficial when attic insulation levels are R-19 or less, or when the air conditioner or ducts are located in the attic. Radient barriers are also useful in walls that take intense sun.
Cleanup after a disaster can be a major problem. Debris from trees, shrubs and buildings may be everywhere. Even though extra resources may be provided, it may be some time before collection is possible. Debris removal will reduce the potential for nesting by rodents, snakes and insects, or it will, at least, keep those infestations in a concentrated area away from the home.

Proper construction of the roof can keep it on the house in a storm. Some roof designs are more wind resistant that others, but even with a good design it's important to strengthen connections and installing materials according to manufacturers instructions for your wind-speed. what happens on the job site can make a huge difference.
Homes in Flood Hazard Areas require special foundations to ensure stability. This article addresses foundation requirements for homes built in wave-action areas.
Termites cannot eat through solid concrete. To enter a structure they must come up around the outside edges or enter through some other opening in the slab. Traditional termite treatments require the application of a continuous chemical barrier to the soil around all possible entry points.
Ways to protect your windows and doors against damage during a hurricane.
Because of their width, double-wide garage doors are more susceptible to wind damage than single doors.
According to recent wind technology research, it's important to strengthen the exterior of your house so wind and debris do not tear large openings in it.
Your home has either double or single entry doors. If they are solid wood or hollow metal they probably can resist wind pressures and hurricane debris. However, if you are not sure whether they are strong enough, take these precautions.
