Product Description

North Shore Commercial Door has garage door threshold weather seal kits in stock and available for fast shipping. These kits give your garage door a tight seal that helps keep water, dust, leaves and pollen out of the garage. These garage door thresholds have been driven-over tested and they will not crack or shatter. They will also remain flexible from 40 degrees below zero to 150 degrees, making this kit ideal for any climate. This threshold kit meets California Fire Marshall and CPAI-84 requirements for flame resistance and comes with a full two-year warranty.

You can purchase these kits in black or gray and North Shore Commercial Door sells these kits by the foot. If you order 16 feet for example, you will receive 16 feet. During installation, you may find that slight more length is needed, so it may be wise to order a slightly longer piece of sealant.

COMMENT: I live in a condo where the gutter above my garage door sags and all the water from the condos uphill from me spills over and floods my garage. I have been trying to get this problem resolved, but because we don't get rain that often the board does not believe the gutter is a problem. I have to take matters into my own hands to solve this problem. tired of my belongings in my garage being damaged by JANET H 12/19/2014
COMMENT: I work in my attached garage and want to use everything available to reduce drafts and rain seepage. by Gregory B 12/18/2014
QUESTION: can i get 4 or 6 inch wide threshold weather seal? by None N 12/11/2014
ANSWER: I honestly don't know, if you absolutely need a wider seal you may have a bigger problem. The seal which I think is just a little under 4 inches should work. I think the better question to evaluate is how tall do you need the seal to be. The box came with very good directions and my issue of water running into the garage was fixed after the 5 minutes it took me to put down the seal. I live in an area with heavy thunderstorms and haven't had a problem since. by Curt M a

ANSWER: I think mine is 4 inches & it works well. Don't remember it coming but in 1 size. by Michael R a
QUESTION: It looks like the 1/2" ridge is not in the center Is there a reason for that? by None N 11/19/2014
ANSWER: The high point of the ridge lies with in the room.The gasket of the door compresses against that steeper slope and does an excellent job stopping water from going up the steeper incline. by Robert F a
ANSWER: The ridge provides a better barrier to water coming in under the door. When I installed my door seal, I placed this ridge under the door on the inside, marked with the pencil where the edge was and applied the glue on the floor. Place the weather seal back on the floor and pull the door down and let dry. by John W a
ANSWER: It's not in the center. You lay the strip down so the edge butts up either against the outer edge of the bottom of the door, or if your door already has a weather seal on it, against the outer edge of the weather seal. The included directions are pretty clear. by Richard H a
ANSWER: Yes. The bottom seal of your garage door seats on the wide flat rubber part of this seal and the ridge acts as a raised barrier of sorts. So when you close the door, from the outside, you will see the raised lip which aids in keeping water and debris out. by Jim S a
ANSWER: Door rests on big side of ridge as shown in picture by ted h a
QUESTION: The garage cement floor is not sloped properly to the drain. I want to use this strip as a barrier across the front of the garage flooring to keep the melted snow/water from advancing to the front. Advice? by Joe L 10/30/2014
ANSWER: I have same issue. Sill get water in my garage even with threshold weather seal by Michael A a
ANSWER: I assume want to keep water from creeping under a closed door.<br /><br />My problem was the wind was blowing the water under the door. The seal stopped it completely with the exception that I had to build up a dam using silicone sealer AT THE ENDS OF THE SEAL. Once the dams were installed I have not seen one drop of water in the garage.<br /><br />I had one other problem that has nothing to do with the seal, i.e., my garage floor had been painted and the adhesive in the kit didn’t bind to the painted surface. If your floor is painted it would be a good idea to ether remove the paint where the seal or installed OR experiment with different adhesives before installing the seal. by Richard F a
REPLY: I want to keep melted snow and water from the vehicles from creeping forward to the back of the garage. I want to use this stripping as a water dam. by Joe L r
REPLY: OK Joe,<br /><br />My guess is the seal is about 5/8" high. I would work as a dam if the water in no higher. If there are seams or expansion joints just fill them with silicone sealer UNDER THE SEAL. by Richard F r
ANSWER: This should do the trick. I would just make sure you put enough adhesive on the strip so you won't have any issues down the road by Young S a
REPLY: Order more glue then Is it waterproof and does it bond to concrete? by Joe L r
QUESTION: Does the glue come with this item or do I need to order it as a separte line item? by Dale B 10/21/2014
