12 signs your contractor is doing a bad job

Most homeowners can't tell whether the work in their house is right. The drywall goes up, the tile goes down, the invoice clears, and the mistakes—if there are any—don't show up for months. Sometimes years. Sometimes the day you try to sell.

You don't need to become a contractor to protect yourself. You just need to know what to look at, and when. Here are twelve signs the trade pros we work with say come up over and over.

1. The site is messy in ways that affect the work

A little dust is fine. A little drywall scrap is fine. What isn't fine: open boxes of materials sitting in puddles, framing lumber stored flat on dirt, finish materials uncovered in a room where someone is cutting tile. Materials get installed in roughly the condition they were stored in. Wet OSB stays weaker. Warped trim stays warped.

2. There's no daily photo log

Good contractors document. They take photos of the rough plumbing before drywall, the framing before insulation, the underlayment before tile. If your contractor can't produce photos of what's about to be covered up, you're paying for work you'll never be able to verify.

3. The same crew isn't there two days in a row

Some rotation is normal. A different crew every day usually means the GC is running too many jobs and subbing out whoever they can find. Quality varies wildly between subs. The person who started your tile job is rarely the person who finishes it if the crew keeps changing.

4. They skip the protection layer

No floor protection on hardwoods during demo. No plastic sheeting between the work area and the rest of the house. No masking on cabinets they're cutting near. These shortcuts save the contractor an hour and cost you a refinish. They also signal a crew that doesn't care about details you'll see—which is a strong predictor of how they treat details you won't.

5. Tile shows lippage you can feel with your hand

Run your palm flat across the surface of newly set tile. If you can feel the edges of individual tiles standing proud, that's lippage—and it's a workmanship defect. Industry standards (ANSI A108) cap lippage at 1/32″ for most tile sizes. Bigger gaps mean either the substrate is out of plane or the setter wasn't back-buttering. Both are fixable—before grout. Not after.

6. The shower pan doesn't slope to the drain

Set a marble on the pan before tile goes in. If it doesn't roll toward the drain from every direction, the slope is wrong. Code requires a minimum 1/4″ per foot. Less than that and water sits, finds the weakest joint, and ends up in the ceiling below. This is the single most common big-ticket failure in bathroom remodels.

7. Caulk where there should be grout (or vice versa)

Caulk goes in changes-of-plane: corners, where tile meets the tub, where tile meets the floor. Grout goes everywhere else. Swapping them causes cracking on one side and water intrusion on the other. If you see a hard grout line in the corner of your shower, it will crack. It's a question of when.

8. Outlets warm up under normal load

Plug a hairdryer or space heater into a new outlet for ten minutes, then touch the faceplate. Warm is wrong. Warm means the back-stab connection is loose, the wire gauge is undersized for the breaker, or the connection wasn't properly tightened. Warm outlets become hot outlets. Hot outlets become fires.

9. Doors don't close cleanly

A new interior door should swing freely, latch on the first try, and stay where you leave it. Doors that bind, swing open on their own, or need to be slammed signal a frame that wasn't shimmed plumb. The fix is easy now. Once the trim is on and the paint is cut, it's a much bigger job.

10. Drywall seams telegraph through the paint

Stand 8 feet from a freshly painted wall, look at it from a low angle with a light source to one side. If you can see every seam and screw, the mud work was rushed. Two coats of compound, sanded flat, primed, then painted—that's the standard. Anything less shows up in raking light forever.

11. The contract has no payment-against-completion schedule

If the payment schedule is structured as “33% to start, 33% midway, 34% at the end” with no specifics about what “midway” or “the end” means, you have no leverage. A real schedule ties payment to specific milestones: framing inspection passed, rough plumbing complete, drywall ready for paint. If your contract doesn't read like that, fix it before the next payment.

12. They get defensive when you ask questions

This is the big one. A pro who knows their work is right will explain what they did and why. A pro who knows their work is rough will get frustrated, change the subject, or imply you're being difficult. Trust that signal. Defensive is almost never about the question. It's about what the question might lead to.

What to do if you're seeing these signs

Don't confront. Document. Take photos—dated, unedited—of everything that concerns you. Save text threads and emails. Get a second opinion from a licensed pro in the relevant trade before you have a conversation with your contractor about it. Walking into that conversation with documentation and an outside read is the difference between a productive negotiation and a dismissal.

That second opinion is what we built Let Me Take A Look for. Upload your photos, get a written Review back from a licensed pro within a few days. $89. No referrals to other contractors, no upsells, no relationship with the person you're asking about. Just a clear read on whether the work is right.
