A draft around a door or window can become much more noticeable once Seattle’s temperatures start dropping.
Sometimes the solution is simple, such as replacing worn weatherstripping. In other cases, the problem may be a door that is out of alignment, a damaged threshold, failed caulking, deteriorated trim or another issue around the opening.
Before adding more caulk or assuming you need a new door or window, it helps to determine where the air is getting in and why.
Quick Answer: How do you stop drafts around doors and windows?
Start by identifying exactly where the air is entering. Common solutions include replacing worn weatherstripping, adjusting doors or hinges, repairing thresholds, sealing appropriate exterior gaps and repairing damaged trim.
If a door does not close or latch correctly, the underlying alignment problem should usually be corrected before adding new weatherstripping.
For Seattle homeowners, it is also worth checking the same area during rainy weather. A draft combined with signs of moisture may indicate a repair that deserves attention before winter.
Why does my exterior door feel drafty?
Exterior doors often become drafty because weatherstripping has worn out, the door is no longer aligned properly, hardware has loosened or gaps have developed around the threshold or frame.
Check whether the door:
- Closes completely
- Latches without being pushed or pulled
- Rubs against the frame
- Has visible gaps around the edges
- Has cracked or compressed weatherstripping
- Shows daylight underneath
- Has a loose or damaged threshold
- Has damaged trim around the opening
A draft does not automatically mean the entire door needs to be replaced.
In many situations, correcting the way the door fits inside the opening can make a significant difference.
Why do doors start sticking during Seattle’s rainy season?
Moisture and seasonal changes can make an existing door-alignment problem more noticeable.
A sticking door may be caused by:
- Loose hinges
- Door alignment
- Swelling
- Hardware problems
- Movement in the surrounding frame
- A damaged threshold
- Deteriorated trim
One thing homeowners should be careful about is simply trimming material off a door without determining why it is rubbing.
If the underlying problem is temporary swelling or alignment, removing material may create an unnecessary gap later.
The better approach is to diagnose the cause first.
When should weatherstripping be replaced?
Weatherstripping should usually be replaced when it is torn, brittle, missing, heavily compressed or no longer contacts the door consistently when it closes.
Weatherstripping helps create a seal around the door.
Over time, it can wear out or become flattened enough that air passes around it.
However, new weatherstripping will not solve every draft.
If the door is sagging or sitting unevenly inside the frame, the alignment issue may need to be corrected first.
Can a damaged threshold cause cold air to come under a door?
Yes. A worn, loose or damaged threshold can allow drafts underneath an exterior door.
With the door closed, look along the bottom edge.
Signs of a possible threshold or door-sweep problem include:
- Visible daylight
- Noticeable cold air
- Water entering underneath the door
- A loose threshold
- A damaged door sweep
- An uneven gap across the bottom
The threshold, sweep and weatherstripping should work together to create a consistent seal.
Should I caulk around a drafty window?
Caulking may help when an appropriate joint around the window has cracked, separated or deteriorated, but it should not be used simply to cover an unidentified problem.
Before applying new caulk, look for:
- Cracked or missing sealant
- Gaps around exterior trim
- Peeling or bubbling paint
- Soft or damaged wood
- Water staining
- Signs of moisture around the opening
If there is damaged wood or active water intrusion, the underlying problem should be addressed before simply sealing over it.
Does a drafty window mean I need new windows?
Not necessarily.
A window may feel drafty because of failed seals around the opening, damaged trim, deteriorated caulking or gaps in surrounding materials.
In some cases, those surrounding areas can be repaired without replacing the window itself.
Other problems may involve the window unit and require a window specialist.
Determining where the air is actually entering is the first step before deciding whether repair or replacement makes sense.
Can rotten trim around a door or window cause drafts?
Yes. Damaged or deteriorated exterior trim can create gaps around an opening and may also indicate that moisture has been reaching the area.
Look for:
- Soft wood
- Peeling paint
- Cracks
- Sections pulling away from the home
- Discoloration
- Visible gaps
Painting or caulking over rotten wood does not repair the damaged material underneath.
Localized trim damage can often be removed and replaced, but it is also important to understand why the wood deteriorated.
That is especially important in the Pacific Northwest, where repeated moisture exposure can turn a small exterior problem into a larger repair.
Should I repair a drafty door before winter?
Yes. Early fall is a good time to identify and repair drafty exterior doors because the problem will usually become more noticeable as temperatures drop.
Seattle homeowners can also use the first rainy days of fall to check whether the same opening is showing signs of water intrusion.
If both air and water are getting through an opening, the moisture problem should receive priority.
A practical repair sequence is:
Identify the cause → Repair damaged materials → Adjust the opening → Weather-seal where appropriate
Repair or replace: when does a door actually need replacement?
Many door problems can be repaired without replacing the entire door.
Adjustment or repair may make sense when the problem involves:
- Hinges
- Latches
- Weatherstripping
- Thresholds
- Door sweeps
- Minor alignment problems
- Damaged surrounding trim
Replacement may make more sense if the door itself is severely damaged, deteriorated or no longer suitable for the opening.
If you are unsure, having the problem evaluated before buying a new door can help prevent unnecessary replacement.
Can I combine door and window repairs with other home projects?
Yes. Drafty doors, weatherstripping, thresholds and trim repairs can work well as part of a larger home repair punch list.
For example, a fall project might include:
- Adjusting a sticking exterior door
- Replacing weatherstripping
- Repairing a threshold
- Repairing damaged trim
- Caulking appropriate exterior gaps
- Adjusting an interior door
- Completing several other small household repairs
Combining related projects can be an efficient way to work through several items during one scheduled visit.
Frequently Asked Questions
How can I tell where a door draft is coming from?
With the door closed, check around the top, sides and bottom for visible gaps, daylight or noticeable air movement. Also check whether the weatherstripping contacts the door evenly.
Does a sticking door need to be replaced?
Usually not automatically. Sticking can be caused by hinges, alignment, swelling, hardware, the threshold or the surrounding frame.
Can a handyman replace weatherstripping?
Yes. Replacing weatherstripping, adjusting doors, repairing thresholds and addressing many related door problems are common handyman projects.
Can a handyman repair exterior trim around a door or window?
In many cases, yes. Localized damaged trim can often be removed and replaced. Any underlying moisture problem should also be identified.
Should I just put new caulk over old caulk?
Not necessarily. Failed material may need to be removed and the area properly prepared before applying new sealant.
