How to Deal with Rotting Wood Window Frames

Rotting wood window frames and sills mean that your window probably isn’t performing as well as it should be, and is very likely on its last legs. A rotting wood window frame or sill isn’t a problem that you can afford to ignore for very long. In addition to your windows causing drafts to enter your home, rotting window frames can be an eyesore and, if left untreated, will surely become a home for mold.

If ignored for long enough, rotting window frames and sills could spread all around the affected area, leading to potentially widespread damage to your home. If you’re waiting on a window repair professional to inspect the problem, there are a few things you can do to alleviate the problem.

How serious is rot?
For homeowners with exterior wood window frames, rot is always a fear. No matter what measures you take, rot will eventually set in and diminish the natural beauty of wood window frames. Rot is caused by moisture coming into contact with the wood exterior over extended periods of time, weakening the frame over time and destroying it from the inside out. While rot is usually an inevitable part of wood being exposed to the elements, it’s not usually a problem that can’t be solved by a professional.

Rot is a timely issue though – failure to address a rotting window exterior can cause irreparable damage to the window frame and lead to lessen performance and mold growth, both of which can significantly affect the interior of your home. All it takes for rot to set in is a small gap that hasn’t been adequately sealed against the weather – once that happens, your windows are at risk. With time working against you, it’s important that you take the correct measures to solve the problem as soon as possible.

How to deal with rotting wood windows
The first step you need to take is to examine the extent of the rotting, as this will help you determine the most appropriate next step. Make sure that the rot hasn’t made its way to the majority of the frame – if the damage is widespread, it’s recommended that you replace the window frame completely. If the damage is contained to a smaller area, you can work to reduce the damage done.

Remove the rot from your window frame or sill using a chisel or screwdriver to dislodge it, and then use a brush to remove debris and dust from the frame. Once this is done, drill a number of ¼ inch holes into the affected wood – these holes will be used to secure an epoxy filler to the frame. When the holes have been drilled into the wood, apply a liquid epoxy consolidant to the wood. Finally, apply and pack an epoxy filler or another wood filler to the frame and mold it accordingly using a putty knife or a paint stirring stick. Once the wood filler has dried, you can go to work on sanding it down until it’s smooth and flat, and then priming and painting it as soon as possible.

While this measure can save your window frames from needing to be replaced immediately, the wood filler solution is considered to be a temporary fix. Eventually, it’s likely that rot will once again set in, and at that point, it’s recommended that you enlist the services of a window replacement professional who will be able to restore your home’s windows to their former glory, and recommend low-maintenance windows materials like vinyl that are far less susceptible to problems like rot and mold.
