Frequently Asked Questions

How do I know if my home needs a repipe?

The usual signs are leaks that keep coming back, weak or uneven water pressure, and brown or rust-colored water. Homes still plumbed in galvanized steel are the most likely candidates: it corrodes from the inside out until the pipe closes up, which is why a spot repair on galvanized pipe is so often followed by another leak somewhere else. If you aren’t sure, a plumbing inspection shows what is going on before you commit to anything.

Should I repipe with copper or PEX?

Both are durable choices. Copper resists corrosion and has a long track record. PEX is flexible, needs fewer fittings and fewer wall openings, and that lowers labor costs. We install both, quote both where both make sense, and tell you which we would choose for your house. The PEX we install is PEX-A by Uponor; our PEX-A vs PEX-B guide explains why.

How long does a whole-house repipe take?

A typical single-family home is repiped in one day; larger homes and commercial buildings take longer. You don’t need to move out. We plan the work so the water is off for as short a time as possible, and patching every opening we make is part of the job, with the walls left ready for paint.

How much does it cost to repipe a house?

It depends on the size and layout of the property, the material, and how the existing pipe runs, so we don’t quote a number without seeing it. We walk the property and give you a free written estimate for the complete job, and the price we quote is the price you pay. Financing is available through our Hearth partner program, and the price is the same whether you pay in full or finance.

What warranty comes with your work?

All repiping, repair, and installation work is warranted against defects in workmanship for 15 years from the date of service. A lifetime warranty is also available on qualifying work; ask about coverage and eligibility when we quote. Full terms are on our limited warranty page.

Are you a licensed contractor?

Yes. Repipe Once is a licensed California contractor, CSLB #1004038, and repipes, sewer line replacements, and gas line work are permitted and inspected. We can pull the permit for you, or you can pull it yourself if you prefer.

Do you do more than repiping?

Yes. We also replace sewer lines, repair and repipe gas lines, replace main water lines, and repair pinhole leaks, for homes, apartment buildings, and businesses. When the problem isn’t obvious, our inspections, from slab leak detection to video camera inspection and gas pressure testing, find it first so the fix matches what is actually wrong.

What areas do you serve?

From our office in Montebello we serve Los Angeles County, the San Gabriel Valley, the Inland Empire, and Orange County. The full list of cities is on our locations we serve page.
