How to stop water from leaking in your garage door

It’s an ugly sight: you’ve opened your garage door early in the morning, only to find that all that heavy rain from last night has left behind a puddle on the garage floor. Not only is it unsightly, but it’s extremely dangerous, too – because anyone could slip and fall, and over time the puddle can cause mould, develop old musty smells and eventually damage your garage’s floor and walls.

Good news for all garage owners: stopping a water leak under your garage door can be relatively straightforward and simple. Here are a few tips from the experts at Doormatic to use once you’ve removed all of the water and are ready to put an end to this puddled mess.

How to stop water leaking through your garage door

  1. Using an adhesive, apply threshold seal to your clean concrete garage floor. This will create a ramp that lets the water slide away and prevents it from entering into your garage. You can get a threshold kit from almost any DIY store such as B&Q or online.
  2. Replace your garage door’s bottom seal with a larger one. However, please do keep in mind that there are a number of different seals out there, and you want to be sure you buy the right one. You will need to know what kind of channel you have; usually this will be single or double.
  3. If your garage floor has a slope, then you will need to get yourself an adjustable aluminium retainer. This item is u-shaped and will fit at the bottom of your garage door so it can be adjusted to fit the slope of the floor.
  4. If you have no luck with the solutions stated above, this could be due to the fact that the rainwater is coming in from elsewhere, such as the roof, windows. If this is the case, you will need to install a drain inside your garage.
