Basement Waterproofing in Orangevale — FAQ

How much does basement waterproofing cost?+

Interior perimeter drain systems cost $3,000-$8,000 for an average basement (80 linear ft). Full systems with sump pump, wall treatment, and exterior corrections run $6,000-$15,000. Costs vary by basement size and severity.

Is interior or exterior waterproofing better?+

Interior systems are less expensive and less disruptive. Exterior waterproofing (excavating around the foundation) is more thorough but costs 2-3x more. For most Sacramento homes, interior systems are highly effective.

Do Sacramento homes have basements?+

Basements are uncommon in Sacramento but not rare, especially in older homes (pre-1960) and homes in the foothills. Crawl spaces are more common and also benefit from waterproofing and moisture barriers.

How often should the sump pump be tested?+

Test your sump pump quarterly by pouring water into the pit until it activates. Check the battery backup annually. Replace the pump every 7-10 years as a preventive measure.
