Inspect The Water Damage On Your Door

Doors commonly get water damaged because they are exposed to the elements. If you suspect that your door is water damaged, especially after heavy rains, inspect your door.

Inspecting your door is crucial to determine which part of your door is water damaged. Then, document the damage on your door, noting that it is essential for your insurance claim.

Also, if you need help with your insurance claim, you can contact your lawyer for assistance. Moreover, review your insurance coverage and policies to ensure that the cause of water damage is included in your insurance.


Door’s swing

Now, for the inspection part, you have to check your door’s swing if it’s working correctly. Just a bit of an FYI, outward swinging doors are typically better designed to prevent water from entering your home.

Also, if you’re looking into hinges that can best protect your door from the harsh weather, then exterior-rated hinges are the way to go. With that said, check your hinges if they are worn out and replace them accordingly.



A threshold is a sloped structure at the bottom of your door that helps keep water out of your house. First, check if your door has a threshold.

If you do have a threshold, then check for water pooling. Examine if your threshold is sloped away from your home or if it’s level across your door’s width.


Overall inspection

This time, inspect your door frame if it’s soggy or rotting. Inspect your door’s surface for signs of water damage as well, like swelling. Check the floor behind your doorway to see if there is cupping.

Lastly, check if the locks, knobs, and handles are working. If they are not working properly, look at this article on repairing water-damaged door jambs.


Does it have rot?

After looking into the state of your door, look into the corners of your door if they have rotted. Rot is caused by water and mold, and it weakens your door’s ability to protect the inside of your home.

You can see if your door has rot if your wood is crumbling and if your door isn’t correctly closing. You can check for crumbling wood using a screwdriver to poke the frame.

If the frame gives away or crumbles, then you may have rot damage. Also, if your door is not properly closing, it may be because your wood has warped due to rot.
