Whether it is the historic Craftsman houses along the Estudillo Avenue or the more recent projects at the edges of the Marina Boulevard, San Leandro homeowners have one concern in common namely the status of their crawl spaces. Having a bayfront position, high table of ground water and old buildings, the city has continued to experience problems with moisture, humidity and soil migration beneath houses.
We seal vents to the outside, support up and vapour barriers beneath to close the special mix of coast moisture and decaying infrastructure to keep your house dry. Your property is located next to Bay-O-Vista, Washington Manor, or Broadmoor, but we develop a long-term solution based on the needs of your foundation.
To gain our reputation in San Leandro, we have combined technology, individual service and craftsmanship. This is what is unique to our team:
We are also more precise and accountable in every project we undertake in such a way that your crawl space is safe, healthy and long-lasting.
San Leandro is an inhospitable location due to the geography, weather, and soil composition. The following are the primary considerations that our team makes anytime we undertake a project:
Foundations are moistened by the wet air brought by the Bay causing the level of humidity to rise.
The soil of the region becomes loose as it swells when it is wet and shrinks when dry leading to shifting supports.
The heavy rainfall in winter then dry summers put a strain on the wood as well as form condensation cycles.
Our encapsulation and repair system is built to withstand such natural factors to ensure that your foundation is firm and dry throughout the entire year.
The old houses in San Leandro have wooden foundations and areas that have not been constructed with the current drainage and humidity conditioning. These buildings are gorgeous but need additional maintenance to avoid ruining with time and nature.
We introduce modern technology in old houses without changing their nature. Our processes such as the accuracy of sealing, moisture control, and unobtrusive insulation reinforce older buildings and do not affect their traditional workmanship. What is created is a foundation that works as reliably as it appears to be timeless.
Most neighborhoods of San Leandro are constructed near the Bay where seasonal flooding and large tides may increase groundwater levels. Such circumstances usually result in wet crawl spaces, cracks on the foundation or a damp smell in the interior of the house.
Our team deals with flood prone areas moisture mitigation. We install drainage pipes, sump pumps, and covered liners so that the standing water is avoided. Any project commences with a meticulous site assessment, in order to ensure that the solutions are developed to address your unique property and soil environments, and to provide all-season protection.
A crawl space repair is a job that is best never done. Proper ventilation, good drainage and regular inspections ensure your foundation is strong and your air is clean in your home. Even the minor preventive measures could always help in the long run.
