Charge once producing the estimate stops being measurement and turns into design. Keep it free when you can walk the job, price it from a book you already have, and be back in the truck inside ninety minutes. The deciding number is not the size of the job. It is hours per estimate set against net profit per job. NAHB's 2026 Remodelers' Cost of Doing Business Study puts the average residential remodeler's net profit at 6.3% of revenue for fiscal 2024, so a $12,000 bathroom leaves about $756. Spend six hours quoting it and lose two of every three, and eighteen hours went into earning that $756. Forty-two dollars an hour, before you pick up a tool.

When is a free estimate still the right call?

When the scope is already decided and the only open question is your number. A 50-gallon water heater swap. A 200-amp panel change. Twelve hundred square feet of LVP over a slab you can see and touch.

Free works on those for a reason that has nothing to do with generosity. The hours are small enough that the job's profit absorbs them even after you count the ones you lose. That is the entire test. Free estimating is not a marketing decision, it is a cost you have quietly agreed to carry, and a cost is either affordable or it is not.

The market expectation is real and you are not going to argue it away. "Free estimate" averaged 61 on Google Trends in the US over the past twelve months, though the term is broad enough that its top related queries include car repair and tax refunds, so treat it as a consumer habit rather than a remodeling figure. The shape of the year is the useful part. It sat at 24 to 26 in late August 2026 and hit 100 in the first week of March, close to a fourfold swing, which means the weeks you give away the most unpaid hours are the same weeks you can least spare them. That index is relative interest, not search volume. It only means something next to another number on the same chart, and it lines up with when homeowners start looking for a contractor.

How many free hours can a job actually pay for?

Take the net profit on the job, multiply by the share of estimates you win, and divide by what an hour of your time costs. That is your ceiling.

You need a cost per hour to run it. The Bureau of Labor Statistics put the median annual wage for cost estimators at $78,740 in May 2025, which is about $37.86 across a 2,080-hour year before payroll tax, insurance, or the truck that gets the estimator to the house. Fifty dollars is a fair loaded number for a working owner. Use your own if you have it.

Job Price Net at 6.3% Estimates won Free hours it can pay for
Water heater swap $2,200 $139 1 in 2 1.4
Bathroom refresh $12,000 $756 1 in 3 5.0
Kitchen, selections already made $60,000 $3,780 1 in 3 25
Kitchen, designed from scratch $60,000 $3,780 1 in 4 19
Addition, schematic design $180,000 $11,340 1 in 5 45

Now put a real number beside those. David Lupberger of RemodelForce reckons contractors typically invest 10 to 15 hours designing and estimating a project before anybody signs anything. Drop that into the table and the kitchen survives. The bathroom does not, by a factor of two or three.

Which is the opposite of the advice most contractors get. Nobody tells you to charge on a $12,000 bathroom. Everybody tells you to charge on the addition, where the hours are large but so is the profit paying for them. The bathroom bleeds because the hours crept up and the price did not.

Count the last addition you bid. Every site visit, every revision after the client saw the first layout, the hour on the phone with the framer, the drive. If you cleared 45 hours on it - and design-from-scratch work routinely does once revisions start - the free estimate cost more than the job would have paid you.

What do you charge for, and do you credit it back?

Doug King, president of NARI and owner of King Contracting in St. Petersburg, Florida, calls the unpaid stretch the incubation room: qualifying, site visits, measuring, photographing, scope writing, take-offs. He splits it into two paid documents. A Client Development Agreement when the client is starting from nothing and needs layouts before there is anything to price. An Estimation Retainer Agreement when an architect's plans already exist and the fee covers assembling the numbers off them.

That split matters more than the fee. It tells the client what they are buying, which is the objection you actually have to answer.

On crediting it back, Michael Stone at Markup and Profit lays out both sides and lands on "it's a business decision." Credit it. The language he points to is worth copying nearly word for word: if the contractor is authorized to complete at least 90 percent by dollar volume of the work proposed, the design fee is credited in full. The 90 percent threshold is doing real work there - it stops a client from cutting one line to dodge the credit, and it stops you from arguing about it later. Crediting the fee should not cost you anything, because the design hours belong in the total job price whether or not you collected them up front.

Set the fee high enough to mean something. The most common mistake among contractors who start charging is a $50 fee, which is too small to qualify anybody and just large enough to make you look petty at the door.

Why does the fee get refused?

Almost never because of the amount. It gets refused because of when you asked.

You drive 35 minutes to Lehigh Acres, walk the house for an hour, take forty photos, sit at the table and then say the plans are $900. From where the homeowner sits you just changed the deal after the visit. Say it on the phone before you get in the truck, in one sentence, and the refusals move to the phone call where they cost you nothing but four minutes. Lupberger's point about the check is the other half: a client who writes one is off the market, because nobody signs a design agreement with two contractors.

What does taking that first check obligate you to?

Paperwork almost nobody sets up, and this is the part that gets skipped. Under 16 CFR 429.0, a door-to-door sale includes a sale of consumer services with a purchase price of $25 or more where the buyer agrees at their own residence - including, in the rule's own words, sales "in response to or following an invitation by the buyer." Your design agreement, signed at the kitchen table, is squarely inside that.

Section 429.1 then tells you what you owe them. A statement in 10-point bold type next to the signature line saying the buyer may cancel prior to midnight of the third business day. And a completed Notice of Cancellation, in duplicate, handed over at signing. Failing to furnish either is an unfair and deceptive act under the rule.

Practically: do not spend the retainer or book the design hours until the third business day has passed. There is an exclusion at 429.0(a)(1) for transactions made pursuant to prior negotiations during a buyer's visit to a fixed permanent business location where the services are offered on a continuing basis, which is one argument for signing at a showroom. Read those four lines yourself before relying on them.

What this misses

The win rates in the table are illustrative. Published bid-hit benchmarks run from roughly 10% on hard-bid public work to 40% and above for negotiated repeat work, and none of those ranges were measured on residential remodels. Use your own last twenty estimates. If you have not tracked them, that is the first thing to fix, ahead of the fee.

6.3% is an average of averages. It is the net margin across remodelers surveyed by NAHB, not a prediction about your company, and a firm running 12% has a very different table than the one above.

None of this is legal advice. States write their own cooling-off statutes on top of the federal rule and several run longer than three days, so check your own before you print a form.

The fee argument is downstream of a document problem, which is why it usually fails on its own. A client who cannot tell what your $900 buys is looking at a page that never said what the work included, and that is the same failure that decides what belongs in the estimate, whether the page you sent was an estimate or a quote, and why the reply never comes. BidWalk builds the scope and the price while you are still standing in the house, which is the cheapest version of this problem to solve: the hours never pile up, so there is nothing to charge for.
