Questions to Ask Before Repiping Your Irvine Home: A Homeowner Checklist for Comparing Proposals
Irvine owners comparing repipe proposals often get documents that look similar but cover different things. A plain-language checklist of questions about scope,…
A repipe is a big project, and Irvine homeowners often collect two or three proposals before deciding. The problem is that proposals rarely list the same things in the same order. These questions help you compare them on equal terms. Ask every contractor the same questions and keep notes.
Licensing and insurance
- Is the contractor licensed in California for this work? You can look up any license number on the CSLB website and check its status and classification.
- Does the contractor carry workers' compensation and liability coverage? Ask for certificates.
Scope of work
- Which lines are included: hot and cold supply to every fixture, the main line from the shutoff, hose bibs, laundry, ice maker, water heater connections?
- Which fixtures get new stop valves?
- Is anything specifically excluded, such as gas lines, drains or the water heater itself?
Materials
- What pipe material is proposed, and why for this house?
- What type of fittings and connections are planned, at a general level?
- Will any existing piping remain in place, and where?
Permits and inspection
The City of Irvine requires a permit to replace water distribution piping. Ask who pulls the permit, how inspections are scheduled, and whether the final inspection is included in the price.
Walls, ceilings and patching
- How many openings are expected, and in which rooms?
- Is drywall patching included? Texture matching? Paint?
- Who handles furniture moving and floor protection?
Schedule and daily life
- How many days of work, and how long will water be off each day?
- Can the family stay in the home during the work?
- What happens if a problem is found behind a wall?
HOA and village rules
Irvine villages such as Woodbridge, Northwood and University Park have active associations. Many require notice for contractor parking, set work hours, or require approval for exterior work. Ask whether the contractor has worked under similar rules and who is responsible for any HOA forms.
Warranty and paperwork
- What warranty covers labor, and what does the manufacturer cover on materials?
- Will you receive a final invoice, permit sign-off and any warranty documents?
Comparing proposals fairly
Put each proposal in a simple table with the same rows: scope, material, permits, patching, schedule and warranty. A lower number that excludes patching or permits is not actually lower. A clear written scope protects both you and the contractor.
Quick takeaways
- Verify the license on the CSLB website.
- Compare scope line by line, not just totals.
- Confirm permits, patching and HOA responsibilities in writing.
