Rotten Windows: Hidden Damage Behind the Frame and When Replacement Is the Best Solution
Why Rotten Windows Are More Than a Cosmetic Problem
You go to crank your kitchen window shut for the night and notice some peeling paint you hadn’t seen before. Without much thought, you head to bed. But the next day you look a little closer and see some moisture stains underneath the missing paint. You figure you can just clean it up and repaint…but what about what’s underneath the stains?
While missing paint, water stains, and water accumulation may seem like harmless and minor cosmetic damages, they might be the first signs of a bigger issue – one hidden behind the window frame: window rot.
What Causes Window Rot?
Window rot is the decay of wood around a window. Once it begins, it can progress quickly, threatening to compromise the wall and studs beyond your window frames. There are 3 main types of wood rot caused by different fungi – brown/dry rot, white/yellow rot and soft rot. The fungi that cause wood rot only thrive in moist conditions. Some of the most common reasons windows start deteriorating from long-term moisture exposure include:
- Water infiltration around the window frame
- Failed seals or aging materials
- Poor drainage around the window area
- Old windows losing their protective, insulating performance
Small Signs of Window Damage You Should Not Ignore
It is a good idea to periodically check your windows for the early warning signs of water damage. Take note if you see any peeling paint or damaged finishes. Other tell-tale visual signs include soft or swollen areas around the frame, cracks or gaps, discoloration, or water stains. If the window frame has significant enough damage, you might start to feel drafts where you haven’t before, condensation between glass panes or difficult opening and closing your windows. You might also notice increases in your energy bills, as window damage can compromise the energy-efficiency of your windows.
| Small Warning Sign | What It Could Mean |
|---|---|
| Peeling paint or finish | Moisture seeping behind the frame; failed seals; poor drainage |
| Soft wood/frame areas | Possible hidden soft rot |
| Water Stains | Potential water infiltration |
| Drafts/Condensation | Aging or failing window system |
What Can Be Hidden Behind a Rotten Window Frame?
If you notice any of the warning signs discussed, it is important to get your windows checked by a professional. What you see on the surface may only represent a small part of potential issues and left unchecked may lead to irreparable damage. Once moisture makes its way behind the frame, the damage can begin to affect surrounding materials and the window opening itself. The biggest concern is that it may not be possible to restore the integrity of wood that has already begun rotting. Delaying repairs when minor warning signs are observed may increase the complexity of the window repair or replacement project, and as a result, increasing the overall cost as well.
Repair or Replace? Understanding Your Options
Where only minor issues are discovered, such as peeling paint or varnish, repairs may be possible. Sanding and refinishing the window frame to stop moisture from seeping through can prevent window rot from advancing. Another way to inhibit damage includes reducing humidity so condensation or ice does not accumulate on windows. However, sometimes minor repairs are not enough to solve window rot problems. Window replacement may be recommended when:
- The frame has extensive rot
- Moisture damage keeps returning
- The window is old and inefficient
- Repairs are no longer cost-effective
