Garage Door Bottom Seal for Uneven Floor

Just the other day, I was speaking to an upset customer. This customer insisted that our technician did a poor job and that he installed their new garage door improperly. The customer stated that there was a gap at the bottom of their garage door. I agreed with the customer that I would personally come out and take a look at the new door installation. One of our newer technicians had installed the door, and figured that this would be a great opportunity to look over his work.

When I arrived at the home, I did notice that there was a gap of several inches on the bottom right corner of the garage door. After speaking with the homeowner, I pulled out a bubble level and checked the level of the garage door and of the concrete. Our technician Eric had done a great job. The culprit of the gap at the bottom of the door was settling concrete.unlevel-concrete-fix-nc

This is not the 1st time that this issue has arisen. Customers are rarely understanding. The claim is always that their old garage door did not have a gap. In nearly 90% of these instances, a wood garage door was removed. These doors are generally more than 20 years old. The concrete settled after the initial installation, and as the concrete began to settle, the door began to sag, thus creating a gap. When a door company installs a brand new door, that’s straight as an arrow, a gap is the result.

So what are your options to close the gap?

The most effective option is to repair your concrete. It’s not a matter of pouring more concrete, but of lifting the existing concrete. It’s a product called PolyLEVEL™. It’s a fascinating product and the cost is quite reasonable. Many Basement Systems Dealers offer this process. Locally, I would recommend Dry Pro Basement Systems.

The next option that we often attempt is over-sized bottom seal. The seal that comes standard on our doors is 3-1/2” long. When this seal is folded in to the bottom retainer it hangs down approximately 1-3/4”. In situations like this, we have the ability to substitute the standard rubber seal for 7” bottom rubber. This is not the ideal solution, but will often keep wind from blowing in to the garage and close the gap.

Before we were aware of PolyLEVEL™, it was not uncommon for our company to employ the use of both threshold and 7” bottom rubber to close gaps on the bottom of garage doors. While it’s always best to opt for repairing your concrete, these other methods have been a value to our company for more than a decade.

Call us today and we will provide you with a vendor to repair your concrete. Our company would be happy to supply you with the materials for other solutions such as longer bottom seal and threshold.
