Keep crawl-space vents open in winter

I used to think the same thing, but the energy crisis of the 1970s led to a lot of research on how to maintain homes to conserve energy.

Over a period of time, it was discovered that making a home substantially airtight would also trap moisture and other gases inside the living environment. Warm moisture-laden air or humid air naturally travels from the warmer areas outside the home to cooler areas inside the home, where it can condensate back into water.

Inside the living areas of our homes, we control the flow of moisture using fans, air conditioners and dehumidifiers. Otherwise, a tightly sealed home could become a garden for mold spores.

We also need to control the levels of humidity in the crawl space, where water vapors can saturate the wood floor system, which then can lead to wood rot, mold growth, decay and structural damage.

Many of the crawl spaces I’ve inspected have elevated-humidity problems. To control the humidity, you open the crawl vents in the winter to allow the warm moist air to flow naturally to the cooler, drier outside environment.

In the summer, you close the vents to keep the warm moist air outside and away from the much cooler, drier air in the crawl space.

However, if you have a water line near one of the crawl-pace vents, that vent should be permanently sealed and insulated to prevent freeze damage to the water line.

Remove garden hoses from water faucets. A modern antifreeze faucet can be damaged if the hose is left in place all winter. If the faucet has an inside shut-off valve, close it until spring.

Check to see if you have a kitchen or bathroom sink with plumbing on or next to an outside wall; the pipes could freeze. To protect the water pipes, leave the cabinet doors open or let the water trickle slowly during the night.

Placing a 60-watt lamp on the floor just outside the cabinet doors also can provide enough additional heat to prevent freezing. Never place a light fixture inside the cabinet.

Insulate the water lines in the crawl space or basement. Insulation conserves hot water while you are using it and prevents condensation from forming on the cold water pipes in the summer.

Locate the main water shut-off valve and make sure it is operable. Most older valves are difficult to close and many will leak when you do turn them off. A minor repair now could save you from an expensive repair later if you are unable to turn the water off in an emergency.

Smith High School parents and staff have complained to the Guilford County Board of Education that their Greensboro school, built in 1963 and last renovated in 2001, has security problems in locker rooms, making thefts a concern.

“This is not the image that Smith High School wants to project to the public,” Donna Matthews, a curriculum specialist, told the board recently. “No student should tolerate the conditions found in these locker rooms.”

“Students deserve secure locker rooms,” said Lisa Comito,Find detailed product information for startup stone mosaic and other products. an assistant principal.Directory ofchina glass mosaic Tile Manufacturers,
There also have been complaints of mold, mildew and insects.

“There is a need to have what other high schools have,” said Arthur Fleming, an assistant principal at Smith High.

Western High School parents say the athletics fields at their school need to be handicapped-accessible and the girls softball field needs bleachers and lights. The school, built in 1968, was last renovated in 2001.

The district also could expand Western High instead of sending students to a new school, said Sheri Bergen, co-president of the Parent Teacher Student Organization.
