Interlock Plumbing Terms of service

Terms & Conditions
Effective Date: February 12, 2026

1. Scope of Services
Interlock Plumbing provides professional residential and commercial plumbing services, including but not limited to plumbing repairs, installations, water heater services, drain cleaning, leak detection, fixture installation, certified backflow testing, boiler certification, maintenance, inspections, and emergency plumbing services.

 
2. Estimates & Pricing
All estimates are based on visible conditions at the time of inspection. Because plumbing systems are often concealed behind walls, floors, ceilings, or underground, unforeseen conditions may be discovered once work begins.

Should additional repairs or services become necessary due to hidden damage, deteriorated piping, code violations, or other unforeseen conditions, Interlock Plumbing will notify the customer and obtain approval before performing additional work.

Unless otherwise stated, estimates are valid for 30 days.

 
3. Payments
Payment is due immediately upon completion of services unless prior written arrangements have been made.

We accept:

Cash
Check
Major Credit & Debit Cards
Returned checks are subject to applicable bank fees.

Accounts that become past due may incur late charges, collection costs, attorney's fees, and any other remedies permitted under California law.

 
4. Scheduling & Cancellations
Customers are asked to provide at least 24 hours' notice when canceling or rescheduling appointments.

Appointments canceled without sufficient notice or missed appointments may be subject to a service call or trip charge.
