Ventilation

Homes today are built more tightly than ever. This saves energy dollars but creates a potential

concern. Condensation, cooking odors, indoor pollutants, radon, and carbon monoxide may all

accumulate. We provide mechanical and passive methods for ventilating homes. Your attention to

ventilation is important to health and safety.

Building codes require attic and crawl space tents to minimize accumulation of moisture. Attic

ventilation occurs through vents in the soffit (the underside of overhangs) or on gable ends. Driving

rain or snow sometimes enters the attic through these vents. Do not cover them to prevent this.

Instead, cover the insulation in front of the vent. When you do this, precipitation that blows in safely

evaporates and ventilation can still occur.

Homes with crawl spaces usually include several vents. Open crawl space vents for summer months

and close them for winter months, pulling insulation over them. Failure to close these vents and

replace insulation may result in plumbing lines freezing in the crawl space. This occurrence is not

covered by your warranty.

Your daily habits can help keep your home well ventilated:

Ø Do not cover or interfere in any way with the fresh air supply to your furnace.

Ø Run the bath fans when bathrooms are in use.

Ø Air your house by opening windows for a time when weather permits.

Proper ventilation will prevent excessive moisture from forming on the inside of the windows. This

helps reduce cleaning chores considerably.
