A damp crawl space or a musty smell after heavy rain can mean water is collecting beneath your home. We install and replace sump pumps, with battery backup systems available.
These are the sump pump services we provide in Covina and the San Gabriel Valley:
Sump pump installation typically takes one visit from assessment to final test. Here is how the process works:
A failing or missing sump pump usually shows warning signs before it stops working completely. A pump does not need to show every sign on the list before it is checked. If water is actively entering the home, call our emergency plumbing line. Planned installation and replacement are different from an active flood response.
Watch for these signs in your crawl space or lower-level storage area:
Most homes in Covina do not have basements, but that doesn't mean that water can't collect in a crawl space or along a low section of the foundation. Our team examines the history of the property. If the same area becomes wet after every storm, stored items have been damaged, or the crawl space stays damp for days, a sump pump may be worth installing. Even without a basement, repeated water entry can cause the same kinds of moisture and water damage people associate with basement flooding.
If none of these apply, a sump pump may not be necessary. We assess the property first and give a direct answer instead of recommending one by default.
Signs a property may benefit from one include:
