Which Costs Less: Epoxy Lining vs Repiping?
Epoxy lining vs repiping fix pipes in two ways. Neither is better for every home; the right choice depends on your pipe’s age, condition, and leak history. Epoxy coats the pipe walls. A repipe swaps in new pipes. Epoxy runs $3,000-$6,000. A repipe runs $4,500-$15,000 (national estimates as of 2026).
How Does Epoxy Lining Work Under a Slab?
We clean the inside of your pipes first. Built-up scale and rust must come out. Then we coat the pipe walls with a thin epoxy layer. It hardens into a smooth, sealed skin. Water runs through the new skin, not the old pipe. In most homes, no slab digging is needed.
We start with a camera check. We make sure the pipe can hold a coat. Pipes that are crushed or split may not pass. If the pipe is still sound, we line it.
Does epoxy lining stop active slab leaks? It seals small leaks and weak spots from the inside. Large breaks or separated joints may need a different fix. Your technician tests the line first to confirm lining will hold.
How Does a Whole-Home Repipe Work?
A repipe gives you all-new pipes. We run new lines through walls, ceilings, or the attic. The old slab pipes stay in the ground, capped off. Water takes the new path from then on. The worn lines under the slab are left for good.
We patch drywall where the new lines run. We cut only what is needed. We keep the work zone clean each day. Most homes take a few days to a week.
Is a repipe noisy or messy? Expect some drilling and cutting sounds during work hours. Our technicians contain dust and clean up daily. You can usually stay in the home while the work happens.
When Does Epoxy Lining Make More Sense?
Epoxy fits best when your pipes are still sound. It works well for a few small pinhole leaks. It suits those who want to keep their floors intact. Homes where new pipe runs are hard to place gain too. If your pipes are still strong, lining adds years of life.
| Factor | Epoxy Lining | Whole-Home Repipe |
|---|---|---|
| How it works | Coats the inside of existing pipes | Installs brand-new pipes |
| National estimates as of 2026 | $3,000-$6,000 | $4,500-$15,000 |
| Best for | Scattered pinholes, sound pipe structure | Widespread corrosion, repeat leaks |
| Disruption | Low, usually no slab digging | Moderate, some drywall patching |
| Typical timeline | 1-2 days | Several days to a week |
Can epoxy lining handle hard water? The cured coating resists mineral buildup well. It gives worn copper a smooth new surface. Your technician can confirm your water type is a good fit.
When Does Repiping Make More Sense?
A repipe wins when leaks keep coming back. It is the right call for thin, rusted runs of pipe. Homes with hard or sour water do best with new pipes. If you will stay for years, new pipes bring real calm. You stop paying for fix after fix.
Can I just keep patching each leak? You can, but repeat leaks add up fast. Three or four spot repairs can cost as much as a repipe. Our technicians review your leak history and show you the math. Then you decide with clear numbers.
What Affects the Final Price of Each Option?
Home size shapes the price most. More feet of pipe means more parts and work. Ease of reach counts too. Open attic runs cost less than tight crawl spots. Pay rates in your town shift the sum too. The shape of your pipes plays a part as well.
We give you a firm quote after a home visit. We list work, parts, and scope line by line. No vague sums. You see just what each fix costs for your home.
Why do repipe prices vary so much? A small one-bath home needs far less pipe than a large two-story. Pipe material choice also changes the price. Your technician will walk through each line of the quote.

FAQs
How long does epoxy lining last?
The lining is made to last for years. How long it lasts rests on your water and pipe shape. We can say more once we see your pipes.
Does repiping increase home value?
New pipes can lift what buyers will pay. It takes a big worry off the table at sale time. Ask your agent what it means for price in your area.
Can epoxy lining fix a slab leak under concrete?
Yes, in lots of homes. The lining coats pipes that sit under the slab. No dig is needed. We must first deem the pipe fit for a coat.
Which option is faster?
Epoxy is the quick pick, at one to two days. A repipe takes more time since new lines go in. We will give you a firm time frame.

Yes, at set times. We plan short shutoffs. We tell you the plan up front. You will know just when the water goes off and on.
