If you’re a garage owner, you’re likely aware of how important it is to be able to seal your garage door to the floor. It stops dust and debris from entering, keeps pests and rodents away and helps prevent draughts. However, if your garage door is installed on an uneven floor, this can make it difficult to create a proper seal. No need to worry, though: we’ve put this blog together to offer some solutions. Here’s how to seal a garage door when the floor underneath is uneven:
Maybe the concrete under your garage door has been deteriorating, or maybe your house has been simply settling over recent months. Whatever the reason, if the concrete under your garage door is otherwise structurally sound, you could relevel the surface by pouring more concrete or using a specialised product that can help you raise the floor where required. This product could be a self-levelling compound, floor levelling screed, or a concrete patch repair kit. All of these can be used to fill in dips or build up low areas to create a more even surface for sealing.
Keep in mind, however, that any floor issues more serious than cracking or shallow dips should be handled by professionals as more extensive repair is likely required. Attempting to repair it yourself may result in damaging the floor further.
If you have an automatic door, have a look at the closing limits of your garage door opener. These switches are used to define the final point of your door closing and are usually set up at installation. Adjusting those could help make sure the door goes down completely, closing some of the gaps. You can do this by using a screwdriver to move the ‘down’ limit switch adjuster on the side of the door, turning it counterclockwise. Use your remote to test how far the door closes after each turn until you’re happy with the result.
If your floor is indeed uneven, this method will likely not fix the problem completely, however it will contribute to a proper seal if combined with some of the other solutions suggested.

Installing a garage door threshold seal is the easiest and most budget-friendly way to seal a garage door with an uneven floor. This type of seal is glued to the garage floor using fixing adhesive and creates a raised barrier that prevents water, dust, debris and pests from entering. It’s a great solution for sealing any garage door with an uneven floor and it’s really easy to install yourself (you can check out our guide on how to install garage door threshold seals here.)
This solution works best in combination with a larger garage door bottom seal, as the two work together to maintain a tight fit, closing any gaps that might be present due to the floor being uneven.
To make sure your garage door creates a proper seal against an uneven floor, consider using an extra large garage door bottom seal. At JA Seals, we offer 50mm rubber garage door bottom seals, which is a size that usually offers enough coverage to make solid contact with the floor. The additional material, combined with your floor seal, will help prevent any openings.
It’s a good idea to test the movement of the door to check if there’s enough clearance before securing the seal in place to avoid any issues with rubbing or catching with other parts of the door. If you need any fitting instructions, have a look at our step-by-step guide on how to fit garage bottom door seals.
