How to tell if home repair work is actually bad
Substandard workmanship shows up as messy wiring, exposed unterminated copper ends, uneven flooring transitions, and dips or humps across newly installed surfaces.

“And I find there are busted rotting boards still.”source ↗
“I noticed there was no obvious kickout flashing, so I asked the project manager about it. He said they used a “weaved cutback flashing” method to prevent leaks.”source ↗
“Looking at the finished work, there’s a lot of white material where the angled trim meets the roof, and the flashing looks like it was wedged against the shingles.”source ↗
“From underneath, the shingles are badly warped and curling, leaving a noticeable gap next to the soffit.”source ↗
“I already know that the builder is going to come up with some stupid excuse and try to say it's normal.”source ↗
“what are things that are wrong that I wouldn't know are wrong until my house is either water damaged or the shingles are blowing off?”source ↗
“Also is it normal for those neon tie straps to be left on for over 100 days?”source ↗
“Please give me some general knowledge I can be confident in for if and when the builders try to tell me it's normal and fine, that I don't know what I'm talking about.”source ↗
“this whole entire roof looks terrible.”source ↗
“I just had my roof replaced last week. I have a porch that has a roof on it that goes into the siding on the back on my house. Its a spot I only see going deep into my back yard but It looks a little messy. I'm not sure if this is just the nature of needing the flash that area or if this is something I should complain about.”source ↗
“a well reviewed local roofing company clearly sent people who have no experience or business working with slate as they walked, sat and rested their tools directly on our 90-year-old slate roof and caused damage.”source ↗
“I am definitely no expert but have never seen flashing look quite like this.”source ↗

“Board should have been replaced due to water damage”source ↗
“Contractor replaced our roof in June of this year. Shouldn’t he have replaced this piece of wood?”source ↗
“I will reach out to him first but my concern is what if he refuses to correct this. What are my options? Please let me know the best way to proceed.”source ↗
“Are there any other questions I should ask him so I they fix the bad workmanship?”source ↗
“There are a couple of sections that are clearly cracked and yes that also makes me worried for what I can't see.”source ↗
“We had this installed today. I told him I was concerned about the overhang. He said it will be fine. I looked it up after they left. I’m pretty sure he’s full of it. I just wanted to put it out to this community to get some confirmation. FYI it’s definitely more than 3/4””source ↗
“Guttering and lead flashing recently installed. I thought they had fully finished everything, though scaffolding still up, and noticed this unsightly gap/damage caused to the render. Is this something I should expect roofer to fix?”source ↗
“I had Ayers Basement Systems in Michigan attempt to lift a floor and level it out. I've had a lot of problems with this company that I'll try to hold back on. This is the end result.”source ↗

“Am I way off here? Is this how it’s suppose to look and a fair price for this type of repair?”source ↗
“I tried to DIY a drip edge extension using a trim roll. It was easy where the gap was wide, but I had to fight it where the gap got tight.”source ↗
“Will seam sealer hold up, or did I totally ruin this?”source ↗
“Feeling pretty defeated.”source ↗
“So the idea is fine, but the execution here is rough. The returns aren't tight, one looks chipped, and the unstained edges stand out.”source ↗
“That is a material issue along with a quality issue. Poor material but the installer should have cut another piece.”source ↗
“Quality of material could have been better, though, I think.”source ↗
“The facia and siding appears to have have many mperfections (to my eyes).”source ↗
“There appears to be a lot of visible seam lines with the facia, as well as gaps all over the place with the freeze board.”source ↗
“The freeze board and facia looks bad.”source ↗
“The work they did was shit, and I told the boss I wasn’t paying.”source ↗
“That sounds pretty sleazy to me. Identify a non-existent problem for an older couple and charge a shitty rate to fix it”source ↗
“Just had new engineered hardwood installed and looking for opinions on what is too picky. I’m concerned with the transitions to carpeted rooms, the transitions to tile and a few uneven places where you can feel dips and humps in the floor.”source ↗
“We paid a company to replace carpets on stairs with laminate. The first round the nosing completely fell off (very unsafe), one of the stairs is completely slanted and the bottom one has some funky looking cuts”source ↗
“The creaking is pretty bad too.”source ↗
“the one stair is slanted, and that bottom stair is still a question mark.”source ↗
“The installer is coming tomorrow to check on it and I am a bit lost right now!”source ↗
“I have only paid half. Waiting to do the “final walkthrough” with them, likely Monday at this point. Would you pay the second half?”source ↗

“I'm having my bathroom remodeled. Completely gutted to the studs, completely new plumbing. Had old cast iron tub removed and replacing with a shower.”source ↗
“Everything I'm reading online says that when cement board is used an additional layer of water proofing should be done. They've got schluter kerdi over the seams and screws, but it's just cement board on the rest of the walls with the tile going over it”source ↗
“I'm really concerned about this. I am having glass tile installed, so the tile itself is not porous, but I know that grout is.”source ↗
“I've also found some chipped edges of tile in the corners. I know that the corners should be caulked, but it looks like they're going to need to use a hell of a lot of caulk to cover it up.”source ↗
“I guess I'm just looking to see how others would handle this. Would you make them rip out the whole shower and start again? Or is that less of a concern due to having glass tile?”source ↗
“I’m not crazy to think this does not look right - correct? One side looks great. Other side has big wedge gaps.”source ↗
“Also over 30 hours later and gently lifted one stone off with zero force. Cured adhesive beneath that hadn’t bonded. Others missing adhesive entirely. Maybe partly incomplete but overall should I be concerned here?”source ↗
