Storm Shield® 20’ Garage Door Seal Threshold Strip - Durable PVC Rubber Seal Strip - Flame Resistent, Weatherproofing Garage Door Installation - Epoxy Adhesive - Made in the USA

So, we remodeled recently and had our garage door replaced. After a couple storms, we noticed that rain water was getting into our garage during heavy storms. We made several adjustments to the door and rubber flange but it still seemed like water was finding its way in somehow. So I did some research and came across the Storm Shield.It arrived a couple days after ordering and came with all I needed to set it up under my 18' garage door. Well, almost all.It was a hot summer day which made installation a bit easier because the strip was tightly rolled up and wanted to roll itself back up whenever I tried to lay it down. I left it out in the sun for a while to soften it up which seemed to work. I carefully measured out how much I needed and drew some lines out so make sure I applied it straight. Once that was done, I applied the glue and laid it down slowly following the guide lines on my garage floor. I used some weights and tape to hold it in place as I went along.As others have mentioned, the included adhesive tube - which sticks very well - didn't seem to be enough to do the job. Also, the tube was very hard to squeeze out all the glue. So, I had a few tubes of liquid nails and a caulk gun and finished the job with that. It was much easier and I should have started that way first.Overall, the strip works great. My door lines up perfectly with the hump and it has done a good job of keeping out the rain water. Definitely worth the purchase.

My garage is waterproof for the first time in 10 years. This product was easy to install and seems like excellent quality of material.Some comments. Do get yourself a gun sized tube of polyurethane glue. They sell a brand at Lowes. Polyurethane glue is the only type rated for both vinyl and concrete. I don't know if what was supplied was enough, but putting it down from those little tubes would have been a major pain on 16 foot door. Also the stuff they supply is best put down at 65 or higher according to the blurb on the tube. The stuff they sell at Lowes can be put down above 40. It was cold when I did it.After I installed it a little water was still leaking underneath the threshold. I guess I left some small gaps in the glue lines or I laid it down a little thin in places. I went back and put a thin bead of glue along the outside edge of the threshold and then it was fine even in heavy rain and snow.A friend installed a different but similar threshold and it leaked a lot. He figured the reason was that the concrete where the threshold sat was uneven and rough and pitted in places. Water leaked underneath in the pitted areas and the door didn't quite meet the threshold in the low areas. He had to take it up and level out the concrete. Put a skim coat of leveling cement on the rough pitted areas and filled in the low spots until it was reasonably close to smooth and level. Then he laid a new threshold and it was fine. I had the same problems with the condition of the concrete, so I followed his advice and tidied up my concrete before I installed the threshold. So these thresholds will give you a waterproof seal but they can't cover up really ratty concrete.I put a new bottom seal on at the same time. With that and the threshold it raised the door up an inch or so, I had to enlarge the hole for the lock tongue and adjust the top door brackets.Other than that I just wish I had done it 10 years ago. Fantastic product.

I exaggerate only slightly. I recently converted my carport to a garage with an overhead door. There were a couple of issues with this. First, the carport slab had no little step down at the overhead door line, as most slabs poured for a garage would have. Second, the slab had a slope built into it from side to side, so it was 1 1/2" higher on the left side of the door than on the right.I talked to the manufacturer of the door about the slope issue. They said that the door had to be installed level, not parallel to the slab. To fill the gap on the right side of the door, they advised me to stuff the right end of the U shaped gasket on the bottom of the door something like a slice of a pool noodle to compensate for the slope. I did my best to a cut a tapered wedge out of the noodle about 6 feet long and pushed it into the gasket. It did look pretty good. I could see just a sliver of light under the far right end of the door, but other than that, it seemed to fill the gap.The next day, we had 2" of rain and water flowed under the door along almost the entire length and there was a torrent on the right side, between the door and wall. I looked outside to see what was going on and saw that the rain pouring off the roof and falling in front of the door was ponding almost an inch deep along the whole length of the door. Part of the trouble was the slab itself. Because it was not exactly as smooth as glass, the seal really couldn't do its job. I live in South Florida and torrential rainfall is a common occurrence in the summer months. I had visions of my newly created garage workshop flooding several times a week.In a panic, I did a search and found the Storm Shield Garage Door Threshold. It looked like it might help, so I ordered it immediately. My door is 12' - 2" wide and the 16' threshold I ordered measured just over 17'. I cut it to length and installed it according to the instructions. The 2 tubes of liquid nails that came with it were just enough to make the beads described in the instructions. If you have a 16' door, I recommend that you pick up an extra tube of liquid nails, just to be sure you don't run out. In addition to the liquid nails, I ran a bead of silicone caulk along the edge of the threshold to seal it. I also cut up some pieces of leftover threshold and made a dam at each end of the threshold, blocking the space between the threshold and the wall, and caulking the spaces as needed.Since I installed it, there have been a number of downpours, but not a drop has entered the garage. I am so happy!
