Remodeling estimating software or a spreadsheet? Start with your own unit costs
Ask general contractors what they bid with and plenty will say a spreadsheet. Others pay every month for remodeling estimating software. In one contractors' thread on exactly that question, the answer that mattered most wasn't about the tool at all: your bids only get tighter when you write down what each job really took. Here's what a spreadsheet does well, where it breaks, what the software costs, and what to check before you pay.

Remodeling estimating software or a spreadsheet: which do you need?
If you bid a handful of jobs a month and know your numbers, a spreadsheet can do the job. Software is worth paying for when you send a lot of estimates, measure from plans, show good, better and best options, or want each estimate tied to job costing.
When a construction student asked a general contractors' forum which software is best for building bids, because their boss wanted to branch out, the most popular answer was spreadsheets. One contractor said a lot of the bid software out there is a spreadsheet with a monthly fee on top. Another pushed back: one broken formula can wipe out the whole margin on a bid.
Quick check · 3 questions
Spreadsheet or software: which fits you?
Three questions. Each yes is a reason software earns its monthly fee.
Answer all three to see which fits.
What a spreadsheet does well, and where it breaks
A spreadsheet is free or close to it, it works the way you price, and your numbers never get locked inside someone else's system. It breaks when a formula goes wrong, when copies multiply, and when the estimate has to become a contract, a schedule and an invoice by hand.
To keep one safe:
- One master template. Copy it for each bid and never edit the master on a live job.
- Lock the formula cells. Only the quantities and the unit costs should be typed in. When one contractor warned about broken formulas, another replied that they triple check the sheet before locking it.
- A check row. A line that should always add up, like labor plus materials plus markup against the total, so a broken sum shows itself.
- A sanity check against a past job. Before a bid goes out, compare its total with the last job of the same kind.
Where a spreadsheet can't help: it doesn't send the estimate, get it signed, remind the homeowner or tell you which bids went quiet. That part needs a system, or a lot of discipline.
The habit that matters more than the tool: your own unit costs
After every job, write down the hours and material it really took per unit you bid by, like per square foot of tile, per linear foot of cabinets or per fixture, and update your numbers. One contractor in the thread said that after 10 or 15 jobs, bids built this way get tighter than anything a software package gives you out of the box.
| Line (Example) | Unit | You bid | The job took | Next bid |
|---|---|---|---|---|
| Wall tile, labor | hours per sq ft | 0.25 | 0.32 | 0.30, the average of 0.28, 0.30 and 0.32 |
| Wall tile, material | per sq ft, with waste | $9.50 | $10.80 | $10.80, and a note on the supplier |
| Vanity install | hours each | 4 | 6 | 5, until the next two jobs settle it |
| Demo and haul‑off | per bathroom | $1,200 | $1,150 | Keep $1,200 |
Example numbers for one bathroom, not benchmarks. Use the average of your last few jobs rather than one bad day, and note why a number moved: a new tile setter, a slower supplier, an old house with nothing square.
Two more lines belong in every remodeling bid. One for what you can't see until demo, like rot behind the tile or wiring that isn't to code. And one that separates what you supply from what the homeowner supplies, because a labor‑only bid and a turnkey bid for the same room can be thousands apart. Our guide on how to bid construction jobs covers both, and our contractor markup guide covers what goes on top.
To skip building the sheet yourself, our free construction estimate template is a bid sheet in Excel and Google Sheets set up this way, with your unit costs, a line for unknowns and three options. If you buy software later, pick one that lets you bring these numbers in and get your takeoffs and cost data back out, so you're not locked in.
What remodeling estimating software costs, and what it does
Simple quoting tools start around 20 to 60 dollars a month. Estimating built for remodelers, with takeoffs, cost catalogs and job costing, runs to a few hundred. Here's what four of them say on their own pages. Prices change often, so check before you buy.
| Tool | Built for | Price on its page |
|---|---|---|
| A spreadsheet | Your own template and unit costs, in Excel or Google Sheets | Google Sheets is free with a Google account |
| Jobber | Quotes, scheduling and invoices for service work. Up to two automatic reminders on a quote | Cheapest plan $21 a month for the first 12 months, billed yearly. The plan with quote follow‑ups, $99 |
| Housecall Pro | Field service software. A Pipeline add‑on automates three estimate follow‑ups | Basic $59 a month, billed yearly |
| Houzz Pro | Estimates from a takeoff, a saved template with your own cost data, or an AI draft, then branded proposals | A free plan, then $99, $199 and $399 a month and up |
| JobTread | Estimates from budget templates, onscreen takeoff and a cost catalog, with target margins per item, tied to job costing | $199 a month plus $20 per internal user |
Jobber, Housecall Pro, Houzz Pro and JobTread prices were read on their pricing pages on 26 October 2026, and the estimating features on 3 November 2026. Several are introductory or yearly prices. Our page on Jobber alternatives compares these tools as CRMs, beyond estimating.
What to check before you pay for estimating software
Test it on a job you've already finished. Rebuild that estimate in the trial, then compare it with what the job really cost. If the software can't get close with your own numbers, a nicer proposal won't fix it.
- Your numbers in and out. Can you import your unit costs, and export your takeoffs and cost data if you leave?
- Your pricing method. JobTread, for one, names fixed price, cost‑plus and time and materials. Make sure the one you use is there.
- Options. Good, better and best on one estimate lets the homeowner choose a level instead of choosing between you and another bid.
- Job costing. Does the estimate become the budget, so the real costs come back to update your unit costs?
- Follow‑up after you send it. How many reminders, by text or email, and when do they stop?
- The hours to set it up. Entering your cost catalog takes evenings. Count them in the price.
The estimate is only half the bid
A tight estimate that nobody follows up can lose to a looser one that does. By the time you send it, the drive, the walkthrough and the write‑up are already paid for, and the homeowner is often comparing it with someone else's.
In Housecall Pro's 2026 survey of more than 1,100 US homeowners, 68% said they get other quotes when a price comes in higher than expected. A quiet estimate is often a homeowner still deciding, and the remodeler who checks in kindly stays in the conversation.
The tools above stop after a set number of reminders: two on Jobber, three with Housecall Pro's add‑on. A remodel can take weeks to decide, so plan what happens after that: Booked follows up every estimate on day 2, 5, 10 and 21 by text and email, in your words, until you get a yes or a no.
For the words, our guide on how to bid construction jobs has a message for each check‑in, from day 2 to day 21.

The math: a midrange bathroom remodel costs $26,138 nationally (Cost vs Value 2025), and remodelers keep 29.9% of the price as gross profit on average (NAHB, 2026). That's about $7,800 from one job.
What is the best estimating software for remodelers?
There isn't one best for everyone. A remodeler sending a few bids a month from their own numbers can do well with a spreadsheet. Someone working from plans, offering options or tracking job costs against the budget gets more from estimating software like JobTread or Houzz Pro. Rebuild one finished job's estimate in each trial and pick the one that matched what the job really cost.
Is there free estimating software for contractors?
A spreadsheet is the free option: Google Sheets costs nothing with a Google account. Our free construction estimate template is a ready bid sheet for Excel and Google Sheets, no email needed. Houzz Pro lists a free plan, and its estimate builder has a demo you can try without signing up. Most estimating software with takeoffs and job costing is paid, from about 20 dollars a month for simple quoting to a few hundred for the full systems.
Can I use Excel for construction estimates?
Yes, and plenty of contractors do. Keep one master template, copy it for each bid, lock the cells with formulas, and check the total against a similar past job before it goes out. The weak spot is a broken formula nobody notices, so build in a check row that should always add up.
How do I make my estimates more accurate?
Record what each job really took per unit you bid by: hours per square foot of tile, hours per vanity, material per square foot with waste. Update your numbers after every job and use the average of the last few. Add a line for what you can't see until demo. Our guide on how to bid construction jobs covers the pricing methods.
Should estimating software follow up on my estimates?
It helps, but check how far it goes. Jobber sends up to two automatic reminders on a quote, and Housecall Pro's Pipeline add‑on automates three. A remodel can take weeks to decide, so plan follow‑ups for after those stop, by text and email, until you get a yes or a no.
