The universal feature of the locally owned houses surrounding and around Garin Regional Park to the older areas of downtown Hayward is one secret they all have in common, which is the activity beneath them. The local climate of coastal air, swollen soil and the changing humidity may contribute to the appearance of severe crawl space problems, such as mould and water accumulation, as well as air pollution in the entire house.
We offer crawl space repair and encapsulation services that are specific to the environment of Hayward. We pay attention to sealing, waterproofing and enhance air circulation to avoid damages before they proliferate. Suburban living close to your Mission Boulevard or the Industrial Parkway, you will have long term solutions to secure your foundation, and make all things easier indoors.
Many homeowners would be surprised to discover that a considerable portion of air in their home, as much as half, enters their home via the crawl space. When such air is mixed with moisture, dust or spores of mould, it influences all the rooms above.
The solutions to these issues are addressed on a root level by closing vents, installing vapor barriers, and enhancing under-home airflow. Having turned your crawl space into a dry controlled area, we assist in making the air that gets into your living areas cleaner and healthier.
Air quality issues usually begin small but over a period, their impact extends. This is what we often find under Hayward houses:
Humid dark environments help mold to grow and spores are spread to your living spaces.
Old insulation and dirt discharge debris which is dispersed by floor vents, and ducts.
Crawl spaces which are not sealed can cause radon or other soils gases to get into the air system of your home.
Avoiding such problems at the beginning of its development, we save the construction of your house, as well as the health of your family members, enhancing both comfort and air quality in the long run.
The musty smell that most home owners feel in the basement or other lower parts of the home can never leave the crawl space. Constant dampness, inadequate air circulation and the growth of molds all result to unpleasant smells that gradually creep all over the house.
Our team will define what the smell is and permanently fix it. We take out the insulation that is affected, cure the mould or mildew and seal up the area to avoid moisture resettling. The outcome is a sweeter, cleaner interior house atmosphere – down to the floor.
As moisture and humidity increases in your crawl space, they bring the allergens along with bacteria and other irritants in the air into your house. These pollutants may also exacerbate allergies, lead to asthma, and have an overall impact on the respiratory condition, particularly during the humid season in Hayward.
To make your indoor air healthier, we put up moisture barriers and dehumidifiers to create a moist free environment that is balanced. Not only do we prevent the growth of molds but also reduce airborne allergens that may destroy the wellbeing of your family.
