Gap under garage door

[Tradcliffe]

Hi all,

I'm in the process of buying a new build, but noticed the garage door doesn't fit snug to the concrete garage floor. About 4-5 ft of the door is approx 1/2" above the floor, while the rest fits properly to the floor. Would you think this is an issue with the installation of the door, or perhaps a poorly poured floor? The builder is saying that it will "flatten out" in the spring when the temperature is warmer, but it sounds like BS. Anyone have experience with this? I've attached a picture for your reference. Any advice is appreciated. Thanks!!

looks like a poorly poured floor to me. The door is probably pretty straight

The builder is lying to you and he knows it. Looks to me like there is a low area in the concrete. Don't expect it to fix itself when the weather changes. It can be fixed with a bit of concrete grinding.

I have a similar problem, but only about 2.5 feet at the end of the right side. I cut a piece of wood from some pressure treated lumber to fill the gap. I thought I might have to glue it down, but it doesn't move much so I never bothered.

This was the builder's response: "In response to the buyers requests based on their inspection report, as it relates to the concrete floor not appearing to be level that is the result of the ground beneath the concrete freezing in the winter causing it to expand, once the the weather warms up the ground thaws and the concrete levels out that's just the way
it is. "

Total bs! Good luck with the fight.

Then have your agent put a clause in the contract that says "if it does not correct itself the builder will tear out and correctly re-pour the garage floor"

I bet that wont go over real good.

That can also be caused by an improperly set cable(drum)
Run a string line or strait edge on floor, or a level at top of door. That will tell you where your problem is. Usually a few minute fix.

^ This or dump a little water at what appears to be the high spot and see what it does.

Seen worst at work 1st is like upndown say make sure door instilled right. If door is right would try installing a bigger bottom seal going from a 3" to 4" bottom seal http://www.americandoorsupply.com/product-p/wrr-400-v.htm or we install Threshold seal .

That garage door is throw away "builder's grade" that often comes with new house. Builder needs to grind down the concrete if the door is in fact installed properly.

I'd be planning on replacing with an insulated door that is worth putting up.

See this video and my thread:

I was able to remove 80% of my gaps just by adjusting the cables for the door.

At least put a level on the floor to see if it is the floor. Don't expect concrete to level itself out with a change of temperature.

 

[jimgood]

If the concrete heaved a half inch on the high side but didn't on the low side, wouldn't it crack the concrete somewhere?
Edit: hmmm...I see there's a seam in the concrete at the middle of the door so I guess the left side could move independently without cracking.

I agree with checking the concrete to see if it's level. Then check the door.

New construction and all, my money is still on a slipped drum or jumped cable.

Try to pull the door down from the side where the gap is, to see if the door will sit flush and close the gap.

If you can do that, and the gap goes away, then you may have an issue with the door hardware on that side sticking like upndown suggested.

If you can't close the gap, or if the gap on that side does close, but then a gap shows up on the opposite side, then the floor is uneven.

I can't tell from the picture, but is there any type of rubber weather strip on the bottom of the door? If not, you could see if you could add one. That would seal the bottom of the door for you.
