How to Choose a Contractor in Ohio Before You Sign Anything

There is a version of this check that takes an afternoon, and there is a version that takes five minutes. This is the five-minute version. It is not thorough in the sense that a lawyer would use the word. It is thorough in the sense that it catches the failures that actually happen: the quote that was never comparable, the uninsured crew, the job that was never permitted and surfaces at resale.

Do it before the first phone call, not after the quote arrives. By the time you are holding a number you like, you are already reluctant to disqualify the person who gave it to you.

1. Write the scope down before you call anyone

This is the step people skip, and skipping it is why quotes come back incomparable. Before the first call, write two or three sentences describing exactly what you want done — the room, the unit, the square footage, whether the old material is coming out, who is putting the surface back.

Then ask every company to price that same scope. What you are buying with this is not thoroughness for its own sake; it is the ability to read three numbers side by side and know that the differences mean something. Without it, the cheapest quote is almost always the one that quietly left something out, and you will not find out which thing until the crew is already in the house.

If a company wants to change the scope — and a good one often will, because they have seen something you have not — that is useful. Ask them to price both.

2. Ask which permit they will pull, then listen carefully

Furnace and air-conditioner replacements, panel upgrades, new circuits, water-heater swaps, and most plumbing alterations require a permit from your county or municipal building department. A contractor who works in your jurisdiction regularly expects the question and answers it in one sentence, usually naming the department.

The answer you are listening for is a specific one. “We’ll pull the mechanical permit through the county” is an answer. “You don’t need a permit for this,” on work that plainly needs one, is the single most reliable red flag in the trades. It is rarely ignorance. It is usually a contractor who would rather not have an inspector on the job.

Unpermitted work is not a victimless shortcut. It can void an insurance claim, it can fail an appraisal, and it reliably surfaces at resale, at which point the cost of putting it right is yours and the contractor is ten years gone. Our Cincinnati permit guide covers which jobs need one and which counter issues it.

3. Get the insurance certificate from the insurer, not the contractor

Ask for a certificate of general liability and workers’ compensation, and ask that the insurer’s agent send it to you directly. That last clause is the whole point of the exercise. A certificate forwarded by the contractor is a PDF; a certificate sent by the agent is a statement by the company that will actually pay.

A legitimate shop does this routinely and without friction, because their agent does it twenty times a month. Hesitation here is information.

Workers’ compensation is the coverage people skip past, and it is the one that can hurt most. Without it, an injury on your property can become a claim against you.

4. Read review volume, not the average

Four hundred finished jobs at 4.6 stars beats four perfect reviews every time. Volume is far harder to manufacture than polish.

You will notice we do not print a star rating on any listing, and this is the one check on this page we send you elsewhere to make. Ratings belong to the platform that collected them, republishing another platform’s aggregate as our own is against their terms, and a figure we copied last month would be a figure we are asserting today without having checked it. Every listing links to the business’s own Google profile instead, where the reviews are current and you can read them the way this section describes.

Three things to look at, in order:

• Depth. How many reviews, over how many years? A shop that has been working since 2004 and has thirty reviews has either just started asking, or has reasons not to.
• Spread. Reviews clustered into one or two months are a campaign, not a reputation. Reviews spread evenly across years are the real thing.
• The three-star reviews. Read these first. Five-star reviews tell you the job went well, which is the normal case and therefore uninformative. One-star reviews are often about something outside the contractor’s control. Three-star reviews are where you find out how a shop behaves when something goes wrong — which is the only question that matters, because eventually something will.

5. Never pay in full up front

A deposit of ten per cent to a third is normal for scheduled work, and on a large equipment order it is covering materials the contractor buys before starting. Full payment before work starts is not normal.

Put the schedule in a written contract that names the scope, the permit, the materials, the start and finish dates, and who cleans up. Where the job needs an inspection, pay the final balance after the permit is closed out — not after the work looks finished. Those are different dates, and the gap between them is where a job quietly goes wrong.

Two more clauses worth insisting on: what happens to the price if the crew finds something behind the wall, and what the warranty covers and for how long. Both are ordinary requests. A company that will not put either in writing has told you something.

What matters most, by kind of job

The five steps above apply everywhere, but they do not carry equal weight on every job.

Kind of job	What carries the most weight
Emergency call-outs — no heat, no water, no power	Availability and a clear call-out rate. You are not getting three quotes at 2am; agree the diagnostic fee before they drive out
Big replacements — furnace, roof, repipe, panel	Scope written down, permit named, itemised written proposal, warranty terms
Outdoor and seasonal — drives, fencing, landscaping	Materials and thickness specified, who calls the utility locates, what happens to plants or surfaces that fail
Cosmetic and interior — painting, drywall	What preparation is included, how many coats, dust containment and clean-up
Small jobs and handyman work	The minimum call-out charge, and whether they will work through a list in one visit

What this check cannot tell you

It is worth being straight about the limits, because a checklist that promises too much is its own kind of risk.

Insurance proves a company carries cover, not that the crew that turns up is any good. A permit proves work was inspected, not that it was well done. Review volume is the best available proxy for consistency and it is still a proxy. And nothing here tells you whether the estimate is fair — only three comparable quotes do that.

What the five minutes buys you is the elimination of the catastrophic outcomes — uninsured, unpermitted, unwritten — from a decision you are otherwise making on gut feel. That is a good trade. It is not the same as a guarantee, and nobody who tells you otherwise is being honest with you.
