Repiping

When patching stops making sense.

A fixed written quote before anything is opened, PEX or copper explained without a sales pitch, and a plan for how your household keeps functioning while we work.

There is a point where each new pinhole costs more than finishing the job properly. If you have patched the same copper three times in two years, if the pressure has been dropping for a decade, or if the grey plastic under your sink is polybutylene, you are already at it. Repiping is not an emergency purchase - it is a planned one, and the whole point of this page is to make the decision feel rational and the price feel knowable before you ever call.

The houses that need it here follow a pattern. Pre-1970 Worthington, Delaware and Old Hilliard homes commonly have galvanized steel that has been rusting inward for fifty or sixty years, and Colonial Hills - built from the early 1940s into the early 1950s - is a textbook case. The 1978 to 1995 window brought polybutylene into the earliest Dublin and Powell subdivisions, which fails at fittings and behind finished walls. And the copper that went into the 1990s and 2000s Powell and Lewis Center building boom is now twenty-five to thirty years old, which is where pinholes start. Three different eras, three different reasons, one conversation.

What you should expect from us is a fixed written quote before demolition, the owner walking the job rather than a commissioned salesperson, and a plain comparison of PEX and copper with the trade-offs stated in both directions. Permits get pulled and the work gets inspected - that is not optional on a job this size, and a contractor who offers to skip it is telling you something important about the rest of their work.

What we do

Repiping work we take on

Water supply lines running through a framed ceiling

PEX repiping

The common central Ohio choice, and usually the right one. PEX runs in continuous lengths with far fewer joints, tolerates a freeze better than rigid pipe, snakes through existing wall and ceiling cavities with much less demolition, and costs less to install because it is faster. Typical whole-house PEX projects in this market land in the $2,000-$10,000 range depending on size and access.

  • Fewer joints means fewer future failure points
  • Less demolition through existing cavities
  • Manifold or trunk-and-branch layout to suit the house

Copper repiping

Longer proven service life, rigid and serviceable, and the material some homeowners simply prefer to have in their walls. It costs more because it takes more labor - every joint is made up individually - and in this market a copper whole-house repipe can reach around $20,000 on a large home. We will price both and tell you which we would put in our own house, and why.

  • Every joint made up and pressure-tested
  • Correct transitions where copper meets other materials
  • Priced alongside PEX so you can compare like for like

Partial repipes and problem branches

Not every house needs everything replaced. When one branch keeps failing - the kitchen run, the second-floor bath, the line to the laundry - and the rest of the system is sound and a different vintage, a partial is the honest recommendation. We also stage full repipes across two visits where a household needs it, so the work fits your life rather than the other way around.

  • Branch-by-branch replacement where that is genuinely enough
  • Staged projects for occupied houses
  • Old runs abandoned in place, capped and labelled

Access, drywall and living in the house

The part nobody explains. We plan the access cuts before we start, keep them square and as few as the layout allows, protect floors and furniture, and leave openings a drywall finisher can close quickly. You will know at quote time roughly how many openings to expect and where they will be, because that is a real part of the cost of the job and it should be in your budget from day one.

  • Access cuts planned at quote, not improvised on site
  • Floors and contents protected, site cleaned daily
  • Openings left square and ready for a finisher

Common problems

What usually goes wrong

Symptoms homeowners call us about, what tends to be behind them, and how we approach the fix.

The same pipes keep leaking

Usually caused by

  • Copper from the same era failing at multiple points
  • Polybutylene fittings letting go one after another
  • Galvanized branches corroded through
  • Household pressure above 80 psi accelerating every failure

Repairs that arrive in clusters are the system reporting its age. We measure pressure first, because a failed regulator is a cheap fix that has been quietly destroying your pipe. If the pipe itself is spent, you get a fixed repipe quote and the arithmetic against continuing to repair, laid out plainly.

Rust-coloured water and pressure that keeps dropping

Usually caused by

  • Galvanized supply corroding closed from the inside
  • Decades of mineral scale narrowing the bore
  • Corrosion scale shedding into the water on first draw
  • Old branch lines undersized for modern fixture demand

Galvanized does not usually announce itself with a flood - it strangles slowly. We confirm by measuring pressure at the hose bib and by cutting a sample section so you can see the actual bore. In a Colonial Hills or Old Worthington house, that cross-section is normally the end of the conversation.

Grey polybutylene pipe throughout the house

Usually caused by

  • Polybutylene supply commonly installed 1978-1995
  • Acetal and crimp fittings degrading with chlorinated water
  • Failures happening behind finished walls without warning
  • Insurance carriers reluctant to renew coverage

With polybutylene the question is timing, not necessity. Because it fails without warning and usually inside a wall, replacing it on your schedule is dramatically cheaper than replacing it on its own. We can stage the work over two visits so the cost lands where it suits you.

You are renovating and the pipes are original

Usually caused by

  • Walls and ceilings already open for other trades
  • New fixtures placing more demand on undersized branches
  • Original supply lines at the end of their service life
  • Additional bathrooms planned on an old trunk line

This is the cheapest repipe you will ever buy, because the demolition is already paid for by another trade. If your house is being opened up anyway and the supply lines are past thirty years, get them priced now - doing it later means opening the same walls twice.

How it works

What happens after you call

Four steps, no surprises. The price is agreed before anything is opened.

Walkthrough and fixed quote

We walk the whole house, identify the material and its condition, count fixtures and runs, look at access, and write a fixed quote. No demolition happens before you have that number in writing.

Plan the access and the schedule

Where the openings go, which day each zone happens, how the household gets water in between. We plan the job so you are not without water overnight, and if a layout makes that impossible you hear it at quote time rather than on day two.

Run new lines, tie in, pressure-test

New supply run in the agreed material, old lines abandoned in place and capped, tie-in at the water heater and the service entry, then a pressure test on the whole system before anything closes up.

Permit, inspection, clean handover

We pull the permit and meet the inspector - that is what a license is for. Then site cleanup, a walkthrough of what changed and where the new shutoffs are, and openings left ready for a drywall finisher.

Reviews

What neighbors say

Five-star reviews from Powell and the surrounding suburbs, unedited.

Keith has done several jobs for us on multiple occasions. He has been available in the evenings as well as on Saturday mornings when it was an emergency. On one occasion, after finishing the job at our house, he willingly walked over to my neighbor's house to help her with her toilet that had broken and was able to fix it right on the spot. He is beyond generous and always informative about the problem at hand. He will tell you what you SHOULD spend our money on and what isn't necessary. I love this about him! I continue to recommend him to everyone I know.
