Your written scope for a plumbing job in Houston

Put the heater size, fuel and location in your written scope, and ask each bid whether the Houston permit and its inspection are inside the price.

What the job covers: which fixtures, pipes or water heater, with size, type and location
If your home was built before 1980, ask whether old supply or drain lines are part of the job
A scale check on the water heater and fixtures, for the ground-water hardness USGS measured in Harris County; test your tap water before agreeing to a softener

Removal and disposal of the old parts or materials
Warranty terms on parts and labor, in writing

This is what workers in this occupation are paid per hour. It is not what a contractor charges for a job.

How does InstaBids work?

InstaBids does not hold payment for the work; you pay the contractor directly on the terms of the bid you accepted.

How is InstaBids different?

Each bidder appears under a stable label such as Contractor A, so you judge the work, not the brand.

Contact details stay hidden until the homeowner picks a contractor and they confirm the connection.

The contact-detail filter can miss disguised contact details.
