How grease trap companies actually find customers
— what 1,914 of them are doing.

Grease trap companies find customers four ways: route density around jobs they already have, standing relationships with property managers and facilities companies, being the number a kitchen already holds when something goes wrong, and being findable at the moment the problem starts. Almost none of it comes from buying leads, because in this trade there is nobody selling them.

We counted what 1,914 of these contractors are actually doing about the fourth one, and the gap was not the one we expected.

Ask this question on Google and you get four answers and a wall of noise. One marketing agency post. A Reddit thread from someone who has just started a grease trap business and is going door to door. A guide to starting one. Then page after page explaining what a grease trap physically is.

That is a thin shelf for a question thousands of operators have. So rather than add another opinion to it, we counted.

They are not invisible. That is the first surprise.

The assumption about small trade operators is that they are absent online. In this trade, that is simply not true.

Whatever else is wrong, “they haven’t got a website” is not the problem. Nineteen out of twenty do. The trade turned up.

But 87% say they are available around the clock, and only 43.5% say when they are open

This is the finding that stopped us. Read those two rows of the table together. Nearly nine in ten say call us any time. Fewer than half will tell you when they are open.

That is not a contradiction the operators intend. It is what happens when “24/7” is a line on a van and business hours are a field nobody filled in. But consider the moment this matters. A kitchen manager has grease backing up at nine on a Friday night. They are not reading your homepage. They are looking at a list of names, and they are choosing between the one that says open now and the one that says nothing at all.

The one that says nothing loses, no matter what its van says.

Nearly half have no reviews. The ones that do average 4.51.

857 contractors — 45% — have zero reviews. Where reviews do exist, the average rating is 4.51 out of 5.

That second number is the important one, and it is genuinely good news. This trade does not have a quality problem. Where customers have said anything at all, they have said the work was good.

What it has is a credit problem. Nearly half of these businesses are doing 4.5-star work and carrying a blank space where the evidence should be. That is not a marketing failure so much as an asking failure — almost nobody in this trade asks.

Put those together and the bar is on the floor

Take a contractor who has done nothing exotic: published their real hours, and asked enough customers for a review to have a handful.

That contractor is now more complete than 56% of the trade on hours and 45% of it on reviews — and in the overlap, more findable than the large majority of the operators competing for the same kitchens.

In a trade of 1,914 businesses, the bar for being the most findable operator in your area is startlingly low. Not because your competitors are bad at their jobs — the 4.51 average says the opposite — but because almost none of them are paying attention to this part at all.

So how do they actually find customers?

Route density. The cheapest job you will ever do is next door to the job you are already doing. Operators who grow steadily grow outward from an existing route rather than scattering across a region. That is a scheduling decision more than a marketing one, and on cost per job it beats most advertising.

Property managers and facilities companies. One relationship can carry a dozen kitchens and renews without a bidding round. Slow to build, very hard to dislodge once built — which cuts both ways depending on whether you are the incumbent.

Being the number they already have. Grease traps become urgent at inconvenient hours. The operator who answers is frequently the operator who gets the work, regardless of price. A phone that gets answered is a marketing channel, and it is the most neglected one.

Being findable at the moment of the problem. This is where the numbers above bite. When a kitchen manager searches, they are not researching — they are solving something happening right now. Hours, reviews and a complete listing are what convert that moment. Most of this trade is leaving all three blank.

What this means if you run one of these businesses

The honest version: you are probably not losing work because you lack a website. You are losing it in the ninety seconds when somebody with a problem is comparing you against two other names and yours is the one with no hours, no reviews, and details you have never checked.

Three things, none of which cost money:

1. Publish your actual hours — and if you genuinely do answer at 2am, say that specifically rather than putting “24/7” on the van and leaving the field empty. 55% of your competition has left it blank.
2. Ask for reviews. You are averaging 4.51 where they exist. The work is not the problem; the asking is. Nearly half your trade has none at all.
3. Check what your listings actually say — on Google, on any directory you appear in. Not what you think they say; what they say. Wrong hours and a dead phone number cost more work than no listing at all.

None of that is marketing you buy. It is an afternoon.

The other moment: being there before anything goes wrong

Everything above is about the emergency — the Friday night backup, the ninety seconds of comparison. That is the moment most operators think about, and it is the one that fills a truck tomorrow. It is not the moment that wins a contract.

Before a kitchen ever has an emergency, somebody at that kitchen asks Google other things. We pulled the questions Google displays across this whole topic on 2 August 2026, and the same ones came up again and again: “Do you legally have to have a grease trap?” (the most common by a distance), “What is the 25% rule for grease traps?”, “What businesses need grease traps?” and “How much does a commercial grease trap cost?”

Those are not the questions of somebody with grease on the floor. Those are the questions of somebody opening a kitchen, facing an inspection, reading a lease, or deciding whether their current arrangement is adequate. They are asked weeks or months before any service is bought — and whoever answers them is in the room when the decision is made.

So who is answering them today? We checked that too. The most-cited sources were a rendering company, a municipal water board, a sewer authority, an equipment manufacturer, YouTube — and, answering “do you legally have to have a grease trap” for searchers in the United States, a drainage company in the United Kingdom.

Almost nobody answering these questions is a contractor who could actually do the work.

That is the gap, and it is a strange one. The people best qualified to explain grease trap compliance in a given county are the operators servicing traps in that county every week. They know which inspectors are strict, what the local ordinance actually requires, and what a realistic service interval is for a busy kitchen. Practically none of them have written any of it down.

This is slower work than filling in your hours. It does not fill a truck next week. But it is the difference between being one of three names on an emergency call list and being the company a restaurant group already trusts before they need anyone.

How we measured this

Every count above is from the GreaseTrapLocator database on 2 August 2026, covering all 1,914 published grease trap contractor listings in North America. Queries were read-only counts of listing fields: presence of a phone number, a website, business hours, review count, and emergency-service flag. The questions Google displays came from 14 page-one pulls across seven grease trap search terms in the United States and Canada on the same date.

Two caveats we would rather state than have you find. This is one directory, not the whole trade — a contractor absent from it is not counted, and our coverage varies by region. And a blank field means the field is blank, not that the business lacks the thing — an operator may well publish hours on their own site while leaving ours empty. That is precisely the point about being findable in the moment, but it is a measurement of listings, not of businesses. This is directory measurement, not client results; we have no client results in this trade to report, and we say so on the evidence page.
