Questions to Ask a Garage Floor Contractor Before Hiring

A printable checklist of questions to ask a garage floor coating contractor before hiring: prep, repairs, materials, moisture, schedule, payment and follow-up.

Why a checklist helps

Estimates move fast. A contractor walks the garage, talks about colors and gives a number, and it is easy to forget to ask the questions that actually decide how long the floor will last. The most-viewed garage coating videos keep returning to the same points: prep, primer, material thickness, moisture and top coat. This checklist turns those points into questions you can bring to every estimate. Print it, write answers next to each one, and compare contractors on the same terms.

Prep questions

How will you prepare the surface: diamond grinding, shot blasting or acid etching? What equipment and dust control will you use? How will you handle the old sealer, paint or coating if there is one? LearnCoatings lists an unground surface as the top reason coatings peel, and Mike Day calls grinding the easiest way to remove old coatings. A clear answer here matters more than any other.

Repair questions

How will you repair cracks, pits and spalls, and with what material? Are repairs ground flush before coating? How many repairs are included in the price, and how are extra repairs priced and approved? How will control joints be treated?

Material questions

What is the base coat product, and what percentage solids is it? What coverage rate will you apply it at? Tim Seay explains that low-solids water-based products lose about half their volume to evaporation, so solids and coverage rate together tell you how thick the floor will really be. Will there be full flake broadcast or a partial scatter? What is the top coat chemistry, and how many coats?

Moisture questions

Do you test for moisture, and how? Is your primer moisture-tolerant or a vapor barrier? Tim Seay notes that most floor primer instructions call for a moisture barrier on slabs on grade and that moisture levels can change over time. What will you do if a test shows high moisture or if blisters appear later?

Schedule questions

Is this a one-day or two-day system, and why? When can I walk on it? When can I park on it? What needs to be moved out, and for how long? Tim Seay says one-day systems can be a good option where moisture is not an issue, so ask how the contractor decides which system to use.

Cleanup and edges

How far up the walls or stem walls will the coating go? Will it stop at the garage door or continue onto the apron? How will you protect walls, doors and the water heater? Who moves stored items?

Experience questions

How long have you been installing floor coatings? Can you describe a recent garage you did that had a similar slab? Do you have photos of prep in progress, not only finished floors? Who will actually be on site doing the work?

Paperwork questions

Will I get a written scope listing every step and product? What is the deposit, and is it refundable before work starts? When is the balance due? What does your written coverage for the work say, and for how long? Ask to read it rather than relying on a verbal description.

Follow-up questions

How should I clean the floor, and what should I avoid? What should I do if I see a problem? Concrete Floor Solutions, in a maintenance video, cleans his floor with a leaf blower and a damp mop, which is a good sign of what normal care looks like.

FAQ: How many estimates should I get?

Two or three is usually enough to compare prep methods and systems, as long as each quote is broken into the same lines.

FAQ: Should I choose the cheapest answer?

Choose the contractor whose answers are clearest and whose scope matches your floor's needs. A lower price is only good value if the steps that matter are included.

How to use the checklist at the estimate

Hand the list to the contractor or keep it on a clipboard and write answers as you walk the garage together. Watch how the contractor responds. A good one will usually welcome detailed questions and may answer some before you ask. If answers are vague, ask the same question again in a different way, or ask for it in writing on the quote. The goal is not to catch anyone out but to make sure you understand exactly what you are paying for.

Questions about the slab itself

Is my slab sound enough for a coating? Are there areas you are concerned about? Do you see signs of moisture, such as white powder or dark spots near walls? Is there an existing sealer? This Old House shows a simple water test: if water soaks in, the concrete is open; if it beads, a sealer may need removal. Asking the contractor to explain what they see shows you how carefully they look.

Questions about the garage door and apron

Most garage coatings stop at the door line. Lowe's notes that many coatings are made for indoor use and can fade in direct sunlight, which is why they tape off at the door. Ask where the coating will stop, how the edge will be finished, and whether the door seal will need adjustment.

Red flags in the answers

Be cautious if a contractor cannot name the products, will not put the scope in writing, dismisses moisture questions, pressures you to sign the same day, or promises results no coating can guarantee. None of these alone proves a bad contractor, but together they are worth noticing.
