Maintenance agreements

Cheaper than the emergency you're preventing

A restaurant kitchen line that gets jetted on a schedule doesn't back up during dinner service. An apartment main that gets cleared once a year doesn't flood a ground-floor unit at 2am on a Saturday.

A scheduled agreement with us usually covers:

  • Jetting on an agreed interval — quarterly, semiannual or annual
  • Camera inspection with each visit or annually
  • Priority scheduling ahead of non-contract calls
  • Locked pricing on the scheduled work
  • Service history documented per address

Tell us the property type and the number of units or fixtures and we'll put a number in front of you.

Multifamily & commercial owners

In the City of San Mateo, a sewer lateral backup or blockage that causes a sanitary sewer overflow at a commercial or multifamily building triggers a required lateral inspection — the overflow itself is the trigger, independent of any sale.

Two pipe cross-sections: a cabled line with a small hole through the buildup, and a jetted line scoured back to the full pipe wall.
Why a scheduled jet beats another emergency cabling.

Vendor packet

License, insurance, references — ready to send.

If you need us on an approved vendor list, ask and we'll send the whole packet: contractor license, certificate of insurance, W-9, and references from properties we already service on the Peninsula.
