There are as many varieties of homes in San Francisco as in the city itself – classic Victorians in Haight-Ashbury, Edwardians in the Richmond District, and hillside homes with a view of the Bay. However, moisture, moving soil and time under such beautiful structures may result in crawl space issues that can influence comfort, stability and housing price. Mist, salty and steep terrain conditions require experience and accuracy in keeping a healthy crawl space in San Francisco.
Our company offers professional crawl space repair and encapsulation services in the entire San Francisco. Our priorities are to save older foundations, increase the quality of air, and avoid long-term water and pest damage. You are about to sell or buying your first home in the city, then you can be sure that our inspections and repairs can help you to help your crawl space to sustain your investment in the city over the years.
Before listing or purchasing a property, our technicians do a full-crawl space inspection to determine hazards and required enhancement. The following is what our process entails:
Such an assessment is useful in ensuring that no secret crawl space problem would be a deal-killer at closing.
The geography and climate of the City of San Francisco also make crawl space issues unlike most cities in the Bay Area. The following are the key environmental issues that we consider:
Perennial fog creates moisture which condenses on surfaces of cold foundations.
Houses constructed on hilly slopes have drainage problems which lead to water flowing below the houses.
Most of the pre-war houses do not have vapor insulations, appropriate ventilation or new insulation.
The encapsulation systems that we have developed are specially made to overcome these obstacles, and they offer dry and stable crawl spaces that will sustain the homes even in the harshest of microclimates.
When purchasing a house in San Francisco, and the house was constructed before 1970s, the state of the crawl space is worth serious consideration. A high humidity, wood decay, or pests intrusion may be expensive to repair once the products are bought.
We provide pre-purchase crawl space inspections that show possible issues prior to signing. Having an understanding of what lies below the house, buyers are able to make the right choices either bargaining over the repairs, planning advancements or budgeting future advancements.
Encapsulation is an added security measure to buyers. Sealed crawl space involves fewer surprises, an improved quality of indoor air, and lower maintenance over time. In the case of older houses of San Francisco, it also assists to maintain historic wood framing and do not allow damp smells to enter the living rooms.
We advise house buyers to inquire about encapsulation in the case of inspections. Our team will be able to check the current systems or develop new ones that meet your further renovation plans and will allow you to secure your investment in the house in the first place.
