Air Quality Techniques

Interior air can be up to five times more polluted than outdoor air.

Maintaining a healthy balance of air quality in your new home can be a challenge. If your home is properly sealed for energy conservation, you also need pro-active techniques to improve interior air quality. All Hamrick homes include:

Low Toxicity Termite Protection Studies show that what’s under a house usually gets into the house, making a low toxicity termite treatment a much healthier alternative to the conventional “soil poison” treatment. The borate-based formula is environmentally friendly and non-toxic to people and animals. It works by contaminating the termites' food source such as wood and other cellulose materials. The contamination kills microbes, which termites and pests need for digestion, starving them to death.

Mold Resistant Construction Techniques Water management around your foundation, including a perimeter drainage system with clean outs, plus watertight window flashings and a continuous drainage plane are needed to keep water out of the house.

Sealed Vapor-Tight Crawl Space and Attic Vented crawl spaces and attics, even though they have been the construction standard for years, actually promote the growth of mold in our humid climate. Sealed and conditioned crawlspaces and attics are a much more effective in controlling moisture and mold growth in your home.

Humidity Control A variable A/C unit with a humidity-sensing thermostat is installed to control temperature and humidity. When humidity control is required during warmer weather, the system adjusts to remove six to seven times more humidity. A dedicated dehumidifier is used for humidity control during other times when the air conditioner is not in use.

Allergy Filter The standard disposable furnace filter traps only about five to 15 percent of polluting particles. Since even the slightest trace of pollutants can trigger unhealthy reactions for allergy sufferers, a whole-house, HEPA-type air cleaner is installed in Hamrick homes to scrub particles from the air. The efficiency of these filters actually achieves up to 95 percent, catching particles smaller than a human hair.

Fresh Air Ventilation System Once a home has been properly sealed during construction, bringing fresh, uncontaminated air inside is essential to the durability of the home and the health and safety of the homeowners. Providing efficient air delivery and filtration systems also helps to dilute pollutants, manage moisture, provide make-up air for appliances and ensure proper house pressures.

Direct Vent Gas Fireplace Many new homes today include house-vented logs and fireplaces, with no exterior venting to eliminate exhausts. Although approved for home use, these systems release carbon dioxide, nitrous oxides and water vapor into the house. This kind of system is bad for your house and dangerous to your health. Direct vent fireplaces remove all flue gases from the house and use outside air as a combustion source. Direct vent fireplaces are healthier, safer and more energy efficient.

Vented Range Hood Cooking adds substantial amounts of moisture and odor to indoor air. Any time the air becomes saturated with more than 50 percent moisture, mold and dust mites grow explosively. This can trigger allergies and related illnesses. Many homes use less expensive “non vented” range hoods, which pass the air through a charcoal filter before returning it into the kitchen. Although the filter may remove some grease and odors, it does nothing to remove moisture. For a mold-resistant home, it is imperative that high levels moisture be vented to the outside at the source.

Better Quality Bath Fans Standard bathroom fans are noisy and ineffective in removing moisture generated from showers and baths. Better quality bath fans cost a little more but are significantly more effective in removing moisture with very low noise.
