About this service

These firms specialize in the installation, inspection, and upkeep of residential and commercial septic tanks. You need them when you are buying a home, planning an addition, or if your current tank shows signs of structural damage. They verify that the tank is watertight and functioning properly, preventing groundwater contamination. Because septic systems are regulated, these companies provide the necessary documentation to show your system meets local code requirements during property transfers or health department audits.

Summer often means more houseguests and increased water usage, which puts extra demand on your septic tank. With more showers and laundry loads, it is easier for a tank to reach capacity. If you have guests coming over, consider a pump-out beforehand to avoid an inconvenient backup during your family gatherings.
