Ideas for cutting concrete

[Mandres]

it would be a lot easier to install gutters and threshold seals to keep the rain runoff away. Trimming a couple of inches off the bottom of the garage door might fix the window alignment.

I don't see any easy way to trim that lip back. It looks pretty rough/jagged too - maybe some kind of angled rubber ramp would help there?

Yes. Gutters will be installed next week. I'm sure that will help quite a bit.

+1 to leave AS IS the concrete at garage door seal. Right now it's higher so water should run off well. If needed, add a thicker rubber seal at bottom of garage door.

Improve building with gutters, etc. as others have suggested.

Was thinking , I know dangerous huh, but how about this. When I cut tile or small concrete jobs I buy harbor fright 4.5" angle grinders that way when the dust takes the out I don't feel bad. I buy a cheap diamond blade(last several projects). You could make a simple sled that hold the grinder horizontal and the blade somewhat under the bottom of the sled. Take thin ply of appropriate thickness and lay it next to the area to be cut. Now you can slide the sled along the ply and mill off the concrete the thickness of the blade. Another pass done with a thinner piece of ply to ride on.

I've never seen the step on the inside of the door and if you live in area where freezing is an issue that would be a recipe for either being unable to open the door or ripping the seal off the bottom. I think you'll find that installing the gutters fixes the water issue. As far as the door fit is concerned, I'd look into trimming the bottom of the door or swap the top two panels of the door.

You can contact the garage door company and should be able to get a shorter panel or panels to correct the door fit. You can get garage doors in increments of much less than the 1 foot standard sizes.

As far as cutting or grinding. At most all I would do is grind to make sure the threshold area slopes out so that water does not run down the doors and into the garage.

That small piece with the drop on it I would have removed and repoured with a simple slope from the garage floor height down to the driveway.

Never see a "concrete floor ledge" around here so freely to ignore my advice if it doesn't apply. Anyway I thought for most garages the floor and the driveway are sloped away so water can't travel up into the garage. The proper slope is usually specified in your local building code.

If done properly you should not need any ledge or threshold. My garage door has a gap about 1/4" between the bottom and the floor. I never have any problem even in heavy rain or snow.

I've seen concrete done like this before, but for a side door not the actual garage door. I mentioned before on how to cut crete with no dust(have done many times) using just enough water so no dust and no harm done to tools! Do have to clean tools really good after.
I just read Radix2 idea and strongly feel thats probably the best route for final look and the labor should be a breeze(not the cheapest)!
