Free Hydronic Heating Specialist Service Agreement

One cracked manifold or a botched pressure test can drown a basement and your bank account in the same afternoon. Without a rock-solid contract, you’re just a glorified plumber waiting for a lawsuit to strip your gear and your reputation.

Pro Contractor Tip

Never lift a wrench for a 'quick favor' without a signed Change Order, or you’ll be eating the cost of those extra zones while the client plays dumb at invoice time.

Why use a written agreement?

Handshake deals are risky. As a Hydronic Heating Specialist, "scope creep" is your biggest enemy. A clear agreement ensures everyone agrees on the deliverables before money changes hands.

Frequently Asked Questions

How do I handle the client who keeps adding 'one more radiator' after the slab is poured?

You point to the Scope of Work section in your signed contract and tell them any additions require a written Change Order with a new price tag—no signature, no heat.

What do I do when the GC delays the project and I'm sitting on ten grand in copper and boilers?

Use a Material Storage and Mobilization clause to bill for equipment as soon as it hits the site; don't act as a zero-interest bank for a GC who can't manage a schedule.

How do I stop getting blamed for a leak that happened months after I left the job?

Ensure your contract includes a Post-Installation Inspection sign-off where the client acknowledges the system was pressure-tested and bone-dry the day you handed over the keys.
