The homes located on the waterfront in Martinez and the tree-lined streets of Walnut Creek, to the hillside homes in Lafayette as well as the older homes of ranch-style homes in Concord, homes in Contra Costa County all have their own special problems under the surface. Crawl spaces in this area are extremely prone to water, stagnant water, and above all to rotting of the structures due to the clayed soils, seasonal rainfalls, and molding terrain of the Diablo Range.
We know the local circumstances that bring about foundation problems, such as inappropriate drainage or increasing groundwater and we implement tested and time-tested solutions. You need to seal the crawl space, waterproof it or reinforce the structure and we are ready to cover your foundation and make your house dry, stable and efficient throughout the year.
The crawl space repair and encapsulation cannot be done just with the help of tools but with experience and accuracy and the willingness to do the job properly the first time. This is what will make our team stand out among the others in the region:
Water may get into a crawl space in multiple ways- and the identification of these causes is the key to permanent remedies. Our technicians inspect each detail of your foundation in order to determine the source and entry of moisture.
Concrete or block walls often have small fissures that may have water leakages during a heavy rain. We close such areas with waterproof paint that is of industrial grade to avoid any additional infiltration.
The downspouts, gutters, and slope landscapes usually lead to the foundation. We divert flow and install yard drainage systems in order to manage runoff.
The houses located on sloping or low-lying plots can have water intrusion under the ground. Our protection of the crawl space is the use of sump pumps and vapor barriers.
A quality sump pump is one of the best tools that can be used to secure your crawl space against flooding. These systems are active to collect and pump away water that gathers under your house, which maintains moisture content to the lowest even on the rainy days most intense in the history of contra Costa.
Our team installs, repairs and maintains sump pump systems that are capable of dealing with the soil and weather conditions of the area. Back up battery solutions to intelligent monitoring systems, we design all of them to your property requirements so that your crawl space is always dry and secure.
In case of heavy flooding in your crawl space, drainage is very essential in the protection of long-term. Water can easily build up under your home because of poor grading, poor waterproofing of the drain lines, or even being blocked by an obstruction of another drain line. The result of this is rotting, mold, and weakening of the foundation.
We develop and install whole drainage systems, which fix the cause of the issue. It could be a French drain, perimeter channel or sub-floor system, but our company will make sure that water is efficiently gathered and moved off your foundation. Even the crawl spaces that are highly susceptible to floods can remain dry and safe throughout the year with the right drainage strategy.
We’re here to help! Swiftly addressing these concerns is key. Our experts will promptly inspect and repair your foundation, ensuring the lasting strength and safety of your home. Reach out without hesitation for reliable assistance.
