Sump Pump + Battery Backup

Keep groundwater out even when the power fails. We test your pump, size the backup, and leave you with clear next steps.

Hamilton basements see two risks—sewer surges and rising groundwater. A backwater valve and a reliable sump pump with battery backup protect finishes and lower flood costs.
