How this calculator works
The calculator multiplies the linear feet you type by the low and high dollars-per-foot you type, then adds the access line to both ends of the band:
pipe low = lf × min(lo, hi)
pipe high = lf × max(lo, hi)
total = [pipe low + access, pipe high + access]If only one of low or high is filled, that number is used on both sides. If linear feet is 0, or both rates are 0, there is no pipe line to show. Access still prints as a dollar so a finish figure you already have is not lost.
There is no house-size multiplier, no "average 3-bed replumb," and no material dropdown that changes the price. Material is a look (see the pipe-material tool) and a rate on a bid, not a national index we do not have.
What each input means
| Input | What it is actually asking |
|---|---|
| Linear feet | Supply pipe being replaced, as a takeoff. Not floor area, not the lot, not "the whole house" as a personality type. Ask the bid to show footage. |
| Low $/ft | The lower installed rate from a written estimate. 0 is the honest default. We will not invent one. |
| High $/ft | The upper installed rate, or a second bid. If you have one number, put it here or in low. |
| Access | Finish, opening walls, slab, crawl, making-good, permit if you are parking it here. The line that does not scale smoothly with footage. $0 if the bid already baked it into $/ft. |
Worked examples
Including one where the naive answer misleads, which is the example most calculators leave out.
Two hundred feet with a real band and an access line
Linear feet 200, low $8/ft, high $14/ft, access $2,000. Pipe $1,600-$2,800. Total $3,600-$4,800. Replace 200 with the takeoff on your proposal and the rates with the numbers on that paper. The addition is the same. Access is the line most whole-house roundups hide.
The same footage with access still unknown
Keep 200 ft at $8-$14, leave access at $0 because nobody has opened a wall. Total drops to $1,600-$2,800. That is not a cheaper repipe. It is a project with a hole in it. The honest move is to keep access visible at $0 until someone who will open the wall prices it.
The one where a national whole-house average misleads
A roundup that says "replumbing a house costs $X in America," typed into the rate box as if it were a bid, or worse, treated as a lump with linear feet left at 0. A 900 sq ft slab house and a 2,400 sq ft two-storey with finished walls are not the same footage and they are not the same access. Applying one national house price to both hides that they fail for different reasons. Type the feet. If you do not have a rate, leave it at 0. A $0 line is more honest than a fake average.
What changes the result
Footage moves the pipe line linearly. Access often does not. Doubling the run from 100 to 200 ft does not double a slab cut, and it does not double a tile bathroom. That is why access is a separate box.
A partial repipe should be typed as the feet being replaced, not as a fraction of a blog "whole-house" number. Replacing the runs that are actually failing, and leaving sound copper, is a different job from a full re-pipe. This form will not know which you are doing unless the footage says so.
Material changes which rate exists. It does not change the arithmetic. PEX and copper quotes for the same layout still differ because of fittings, routing and labour, which belong in the $/ft you were given, not in a dropdown we would have to invent.
Local considerations
Labour, permit fees, whether the plumber pulls the permit, and whether a slab or a crawl is typical on your street are local. None of those belongs on this form as a state dropdown that changes the price. A state labour index without a sourced series would be a fake localiser. Your bid and your building department are the local data.
Lead service lines are a utility and lot question, not an interior takeoff. EPA has a separate replacement conversation for those. Do not put the public-side service in this footage unless the bid actually includes it, itemised.
When not to use this
Do not use this as a quote, a loan figure, or proof the project is affordable. It cannot see the slab, the finish, or a takeoff that missed a wing of the house.
Do not use a whole-house average from a blog roundup. If you cannot name who priced it, on what footage, in which city, leave the rate at 0.
Do not use the year-built tool as a reason this footage must be replaced. A year is a prior. Confirm the material by looking, then price the feet that are actually coming out.
HyrePlumber does not perform plumbing work. Matching is still being built. The enquiry form is not a dispatch line.

Questions this calculator answers
- How much does it cost to replumb a house?
- Whatever the linear feet, the $/ft, and the access line add to, in this house, on this bid. We do not publish a national whole-house average because a ranch on a crawl and a two-storey on a slab are not the same job, and a partial repipe is not a whole-house number with the name changed.
- Why will you not give me a whole-house price?
- Because a single house price pretends footage, access and finish scale smoothly with "a house." They do not. Type the feet the plumber measured and the rate on the paper. Until you have those, leave the rates at 0.
- What counts as linear feet?
- The supply pipe being replaced, as a takeoff, not the floor area of the house and not the lot line. Hot and cold are often separate runs. A water-heater connector is not the system. Ask the bid to show footage, not just "whole house."
- What belongs in the access line?
- Finish, slab, crawl, opening walls, making-good, and any line that is not the pipe itself. Getting to it is often more work than the pipe. If the bid already folded access into $/ft, leave this box at $0 so you do not double-count. If the bid is pipe-only, type the finish number here.
- Should I type one rate or a band?
- A band if the bid is a range, or if you have two bids that disagree on $/ft for the same footage. Type the lower in low and the higher in high. If you have one number, put it in both, or in one and leave the other at 0. The engine will use whichever side you filled.
- Is PEX cheaper than copper on this form?
- Only if the bid says so in the rate. This page will not apply a material discount. Copper, PEX and a mixed job fail for different reasons (see the pipe-material tool). The dollars are the rate you type.
- Do I have to replumb the whole house?
- Not because this page said so. A single mechanical failure on otherwise sound pipe is often a repair. Repeated leaks on the same run, falling pressure throughout, or a known problem material is the conversation. The year-built tool is a prior, not a diagnosis that your walls contain a given plastic.
- Are permits in the access line?
- Only if you put them there. Water-supply repipes are usually permitted work. If the bid itemises the permit, it can live in access or you can add it to that box. $0 means untyped, not exempt.
- Is this a quote?
- No. It cannot see the slab, the finish, a crawl that is not as advertised, or a second bathroom the takeoff missed. Use it to tell whether a bid has priced footage and access as separate ideas. Minus something to plus a lot, because unseen conditions add money.
- Does HyrePlumber replumb houses?
- No. HyrePlumber does not perform plumbing work, pull permits, or warrant a repipe. Matching is still being built. The enquiry form is not a dispatch line.
