Wood Doors: Why They Expand and Swell

Written by P.J. Sullivan | Oct 8, 2020 2:30:15 PM

According to experts, wood doors are one of the best door options you can consider for your home. If you pick the correct door from the correct brand, door replacement companies say it can easily improve your home’s overall appeal and energy efficiency. However, when you buy a wooden door, there is a recurring problem you need to look out for: expansion and swelling.

Here’s why wooden doors expand and swell.

Why Wood Doors Expand and Swell

When it comes to wood door expansion and swelling, door and window replacement companies say that the main reason why it occurs is due to the combination of insufficient water-repellent finishes and moisture. Remember: moisture is the number one enemy of wood. If your wood door isn’t properly sealed or finished, it can easily cause expansion and swelling of your door if left unattended.

Alternatively, the placement of your door and the location of your home could also be the reason as to why your wooden doors expand and swell. For instance, if you live in an area that has a lot of sunlight, wooden doors that are located in the southern and western areas are more exposed. This compromises the door’s protective finish and without it, it won’t take long for your wood door to start swelling as a result.

How to Prevent Swelling

If you have a swollen door, it can be harder to operate. Unfortunately, once your door’s swelling is so severe, there’s not much you can do but have it replaced. If you’re looking to prevent wood door swelling in the future, on the other hand, experts recommend that you reduce indoor humidity by opening your windows or turning on your exhaust while cooking or showering. Regular maintenance of the door can also prevent swelling. Apart from that, you can also have an expert refinish it to fix the problem.
