The houses of the city, starting with the hillside houses in the areas around Claremont and the old architecture of the Shattuck Avenue and continuing to the Craftsman homes surrounding North Berkeley were constructed many decades ago, at a time when moisture control was not a key concern in home building. The cool marine air and the fog of the Bay in Berkeley tend to result in wet crawl spaces that can silently undermine the construction of a house and affect the quality of air.
Crawl space repair and encapsulation provide a clean and sealed area under the home that would avoid the accumulation of moisture, mould and rot of wood. The insulation and dehumidification of the crawl space will help the homeowners of Berkeley secure their foundation, enhance airflow, and also sustain the same interior climate throughout the year.

An important element of a good encapsulation system is dehumidifiers. Although the vapor barriers can keep most of the humidity out of the crawl space, the remaining humidity which naturally gathers in the air is controlled by dehumidifiers.
The dehumidifiers are even more important in the cool and damp climate of the coasts of Berkeley. They decrease air moisture which may be transferred upwards through floor boards safeguarding the crawl space as well as the living space above.
An effective crawl space system incorporates various necessary elements which interrelate in order to avoid moisture and ensure the structure is sound:
Drainage is a condition whereby the groundwater is directed to drain off the foundation to avoid standing water.
Keeping humidity levels in the air at a safe level.
Excluding the outside air into the crawl space by closing the gaps and vents.
Everything is a part of a solid dry base – the home is preserved against the harm of the damp weather that prevails in the coastal climate of Berkeley.

The air that gets into your house does not begin at the living room but it starts below your feet. Crawl space air in most Berkeley houses enters the house through small holes on the floor and brings moisture, dust, and allergens. This may eventually affect the respiratory health and predispose the indoor environment to mold-related problems.
Encapsulation makes a closed system which does not allow external air and pollutants to enter. This combined with dehumidifying and good ventilation will lead to cleaner drier air being circulated throughout the entire home.
Despite the well intentioned encapsulation mistakes can result in trapped moisture or ineffective protection. The most widespread mistake is to use thin and low-grade plastic as a vapor barrier – materials that are easy to tear and cannot create an airtight layer. The other error is the sealing of the crawl space without prior consideration of drainage problems which may trap standing water under the liner.
Berkeley has a changing climate that can result in condensation issues in vents that are not sealed with no moisture control and the openings that are open to the outside humid air. The most effective solution is to measure moisture causes, close with proper seals and balance moisture regulation of air to keep long-term achievements.
Crawl space maintenance, despite the appropriate repairs and encapsulation, must be maintained over time even in such a city as Berkeley, which is located on a shoreline changing moisture levels over a year. Even basic and regular maintenance can do a lot to help avoid emerging problems and maintain the stability of your home.
Make sure to circulate air in closed areas to avoid stale air in the humidity.
During wet seasons in Berkeley, use a hygrometer to determine the level of moisture.
Check after seasonal storms to see evidence of standing water or wet insulation.
We were very happy with the results of our inspection with Ryan! He explained the settling in homes and what things we should look for, and was very professional, friendly, and efficient. Thanks!
Had a great experience working with Kyndell from Golden Bay Foundation Builders. I recently purchased the home and was looking for help with earthquake retrofitting options. He inspected my foundation carefully and determined that past bolting was likely adequate. He had suggestions about monitoring the foundation. He was very thoughtful and detailed in his approach, and worked to determine what was best for the home. In this case, that meant no need for additional work now. But if I need any additional assistance in the future, will be calling him again.
