Plumbing estimating software

Plumbing estimating software that fits how plumbers actually bid.

Most plumbing estimating software was built for big mechanical contractors with full-time estimators. ScopeGauge is for the owner-operator and the small crew writing bids between service calls. Describe the job, review the line items, and edit every number.

14 days free. No credit card. No commitment.

Built for the jobs you already price every week

Describe the job the way you would explain it to your crew. ScopeGauge writes the line items, prices the materials, and hands you a proposal you can send before lunch. You stay in charge of every number.

  • Water heater swaps - gas, electric, tankless - with venting and code parts called out
  • Whole-house repipes - copper to PEX with rough and trim line items broken out for the GC
  • Sewer line repair pricing - spot repair vs. liner vs. full replacement
  • Bath remodel rough-in priced by fixture count and access conditions
  • Drain & rooter service call pricing with the camera-inspection upsell line item
  • Gas line work - appliance reconnects, range and dryer installs, pressure-test line

No drop-downs, no part-number lookup

Other plumbing estimating tools make you click through assembly templates and SKU catalogs. ScopeGauge can start from a job note like: "50-gallon gas heater, attic, expansion tank, pan with drain."

Calibrated to your shop

Professional and Business plans calibrate from your completed jobs. Mark bids won or lost, and ScopeGauge updates pricing for your market and trade. Not a generic national average.

Send a proposal the same day

Customer-ready proposals come out of the same workflow that built the estimate. No copy-paste, no second pass at midnight.

What does this look like in practice?

Here's what a typical scope looks like going in, and the line items it might come back with. Every number is editable before the proposal goes out.

You type something like

"50-gallon natural gas water heater swap, attic location, existing pan has no drain, customer wants a tankless conversion estimate too."

ScopeGauge could break that into line items like

  • Permit + inspection coordination
  • 50-gallon natural gas water heater (your preferred brand)
  • Power vent kit + vent termination (reuse or new)
  • Expansion tank (code-required in most residential)
  • New T&P relief valve + discharge
  • New gas connector flex + sediment trap
  • New shut-offs (cold inlet, gas)
  • New pan with drain line to exterior
  • Demo + disposal of existing unit
  • Labor - 6 hours @ your shop rate
  • Materials markup
  • Alternate: Tankless conversion line (gas resize, vent, electrical, condensate)

Illustrative. Every estimate is editable before send. The more detail you give the input, the stronger the first draft. ScopeGauge isn't producing a fixed catalog answer, it's building a starting point you can review and adjust.

What ScopeGauge does, and what it does not do

We'd rather be clear about scope than oversell. Here's where ScopeGauge earns its keep, and where you should pair it with something else.

Built for

  • Job description to editable plumbing line items
  • Pricing service calls, water heaters, repipes, sewer work, bath rough-ins
  • Customer-ready proposals (Pro/Business)
  • Calibrating to your shop's real pricing over time (Pro/Business)
  • Win/loss tracking that sharpens future estimates

Not built for

  • - Blueprint takeoff - pair with Bluebeam, PlanSwift, STACK
  • - IPC / UPC code compliance - you bring the code knowledge
  • - Permit submission - you still file with the AHJ
  • - Pressure-test or hydrostatic calcs - engineering, not estimating
  • - Accounting / invoicing - pair with QuickBooks
  • - Dispatch / route optimization - pair with ServiceTitan, Housecall Pro

The line items that quietly kill margins

Every experienced estimator has been bitten by these. ScopeGauge surfaces them so they don't end up as "I'll eat it" at the end of the job. You decide whether to bill, absorb, or skip.

Missing the gas pressure test line

Required on gas line work, takes real time. Buried in "labor" = eaten on competitive bids. Break it out so the customer sees it as a regulatory cost.

Forgetting demo + patch on access cuts

Drywall, tile, cabinetry - the patch-and-paint either gets done by you (line it) or by them (note the allowance). Either way it should not be silent.

Missing the dump trip on remodels

Old PEX, copper, fixtures, packaging. The dump fee + truck time is a separate line, not buried in markup.

Camera inspection vs. drain clearing

Simple clear is one rate. Camera + recording + report for insurance is a different scope. Same call, different line items.

Skipping the inspection re-trip

Whole-house repipes, sewer replacements, water heater swaps all get inspected - 1-in-10 needs a re-trip. Price it or absorb it.

Missing disposal of old fixtures

Old 80-gallon to scrap yard, dump fee for old fixtures. Easy line to forget, easy line to defend when itemized.

Pricing

Common questions

Is ScopeGauge a takeoff tool too?
No. We focus on the estimating and proposal workflow, not blueprint takeoff. If you're bidding from plans that need full quantity takeoff, you'll pair ScopeGauge with whatever takeoff tool you already use.
How is this different from spreadsheets?
Speed and consistency. Spreadsheets are flexible but slow because every job is a rebuild. ScopeGauge produces a first estimate from the job description in minutes, with consistent line-item structure, then you edit the numbers before sending.
How is this different from generic AI tools?
Generic LLMs don't keep your pricing history, don't structure proposals consistently, don't integrate with your invoicing, and have no calibration loop from won/lost bids. ScopeGauge is built around the contractor workflow.
How accurate is it?
We don't quote a specific accuracy percentage because every job is different and accuracy depends on the detail you give it. ScopeGauge produces a strong first draft and you edit before sending. The Bid-Off Challenge is the right way to find out how close it gets on your kind of work.
What does it cost?
Starter $199/month, Professional $349/month, Business $499/month. All plans include a 14-day free trial with no credit card required.
Is my pricing data private?
Yes. Your labor rates, markups, and competitive pricing stay yours. We never share them with other contractors or use them to train shared models.
