You've sealed every gap you can find, but cold air is still blasting through your entryway every time the wind picks up. You spent Saturday afternoon pressing weatherstripping into every crack around your front door, convinced you'd finally stop throwing money at your heating bill. But here's the thing — the draft didn't go away.
That's because most drafty door problems aren't actually coming from where you think they are. If you're dealing with persistent cold air infiltration after weatherstripping, you need to understand what a professional Door Supplier in Vancouver BC looks for when diagnosing these issues. And honestly? Most of these problem spots are completely invisible to homeowners doing DIY fixes.
The Three Hidden Air Leak Spots You Probably Missed
Your door itself might be perfectly fine. But cold air doesn't care about your weatherstripping if it's sneaking through the frame, threshold, or wall cavity instead.
First spot: the threshold underneath your door. Over time, that metal or wood piece at the bottom wears down, warps, or settles. You can seal the sides of your door all day long, but if there's a quarter-inch gap under the sweep where the threshold has degraded, cold air is pouring in constantly. Run your hand along the floor on a windy day — if you feel airflow, your threshold is shot.
Second spot: behind the door trim. Most doors have decorative casing around the frame on the interior side. Behind that trim? There's usually a gap between the rough framing and the door jamb. Builders are supposed to fill that space with insulation, but pretty often they skip it or do a terrible job. Cold air travels through your wall cavity, hits that uninsulated gap, and blows right into your house through tiny cracks you can't even see. You won't find this one with weatherstripping.
Third spot: the hinge side of the frame. Everyone focuses on the latch side because that's where the door closes. But the hinge side can develop gaps over time as the door settles or the house shifts. If your door was installed slightly out of square — which is super common in older homes — the hinges might be pulling away from the frame just enough to create a permanent air channel. Weatherstripping can't fix a structural gap.
What Your Door Supplier Checks That You Probably Missed
Here's what professionals look for when a homeowner calls about draft issues that weatherstripping didn't solve.
They check the actual door slab for warping. Wood doors especially can twist or bow over time, particularly if they've been exposed to moisture or temperature swings. Even if your weatherstripping is perfect, a warped door won't seal evenly against the frame. You'll get compression in some spots and gaps in others. A Door Supplier can tell you within thirty seconds if your slab is the problem — they just close the door, stand back, and look at the gap line. If it's uneven, the door is warped.
They also check the jamb itself. Your door frame can rot, especially at the threshold area where water tends to collect. If the jamb is deteriorating, it's not providing a solid surface for your weatherstripping to seal against. You might feel the weatherstripping compress when you close the door, but underneath it's squishing into soft, rotted wood instead of creating an air-tight barrier.
And they test the door's swing and latch alignment. If your door isn't closing properly — maybe the latch barely catches, or you have to slam it to get it to stay shut — that's a sign the frame has shifted or the hinges are loose. No amount of weatherstripping fixes a door that isn't closing all the way in the first place.
When Draft Issues Mean Replacement vs Simple Fixes
So when do you actually need a new door versus just some adjustments?
If your threshold is worn but the door and frame are solid, you can usually replace just the threshold. It's a straightforward repair that costs way less than a full door replacement. Same thing with adding insulation behind the trim — messy job, but fixable without touching the door.
But if your door slab is warped, that's replacement territory. You can't un-warp a door. And if your frame is rotted — especially if the rot extends into the structural framing around the opening — you're looking at a bigger project that involves pulling the whole unit and possibly repairing the rough opening too.
Here's the test: if you've addressed obvious weatherstripping gaps and the draft persists, it's time to have someone who knows door installations actually diagnose the problem. Because the real issue is probably structural, not surface-level.
Why Vancouver's Climate Makes This Worse
The constant moisture here accelerates every door problem you can think of. Wood swells, metal corrodes, and any tiny gap you ignore in August becomes a wind tunnel by November.
If you're also dealing with window issues, like your bow windows fogging up or drafty, that's often a sign that your home's overall weatherproofing has degraded. Bow Window Replacement in Surrey BC is another common need for the same reason — failed seals and moisture damage from our wet climate. Windows and doors age at similar rates, so if one's failing, the other probably isn't far behind.
The key thing to understand about BVS Windows & Doors Ltd or any reputable supplier is that they're not trying to sell you a new door when you don't need one. But they also won't waste your time (or theirs) on surface fixes if the underlying problem is structural. If your door frame is shot, weatherstripping is just putting a band-aid on something that needs surgery.
What Actually Happens During a Professional Assessment
When you call someone out to look at a draft problem, here's what they should be doing — not just selling you something on the spot.
They'll inspect the entire door assembly, not just the parts you've already tried to fix. That means checking the rough opening behind the trim, testing the threshold with a level, and looking for signs of rot or damage that indicate bigger issues. They'll also close and open the door multiple times to see how it's moving — whether it's dragging, whether the latch is catching properly, whether there's any play in the hinges.
Good Door Supplier assessment also includes asking when the door was installed and what material it's made from. A fifteen-year-old wood door in Vancouver has probably seen some moisture damage. A newer fiberglass door shouldn't be warping, so if it is, something else is wrong with the installation.
And they'll be honest about whether this is a repair situation or a replacement situation. If you need a new door, they should explain why — not just "it's old" but "your slab is warped past the point where adjustments help" or "your frame has rot extending into the structure."
If they're just trying to sell you their most expensive door without explaining what's actually wrong, that's a red flag. The right supplier walks you through the diagnosis and gives you options, not a hard sell.
Your drafty door after weatherstripping isn't a mystery to someone who installs these things for a living. But you have to actually let them assess the real problem instead of assuming more weatherstripping is the answer. Because if the issue is structural — and with persistent drafts, it usually is — you're wasting time and money on fixes that were never going to work. When you're ready to solve the draft problem for real instead of just covering it up, working with a qualified Door Supplier in Vancouver BC makes all the difference in getting it done right the first time.
Frequently Asked Questions
Can I just add more weatherstripping to stop the draft?
Not if the problem is behind the trim, in the threshold, or from a warped door. More weatherstripping only helps if the surfaces it's sealing against are straight, solid, and aligned. If your door frame is rotted or your slab is twisted, adding more foam strips won't create a better seal — it'll just compress unevenly and fail faster.
How do I know if my door frame is rotted without tearing into the wall?
Look for soft spots, discoloration, or flaking paint around the threshold and bottom of the jamb. Press gently on the wood — if it feels spongy or gives under pressure, that's rot. You can also check for water stains or mold growth on the interior trim, which usually means moisture is getting into the frame cavity.
Is it normal for old doors to be drafty no matter what I do?
Sort of, but "old" doesn't automatically mean unfixable. A well-maintained wood door from the 1980s can seal just fine if the frame is solid and the door hasn't warped. But if it's been neglected — exposed to weather, never repainted, hardware never adjusted — then yeah, at some point the cumulative damage makes a new door the smarter investment than endlessly patching an old one.
Will a new door actually solve my heating bill problem?
If your current door is legitimately drafty, yes — a properly installed, energy-efficient door makes a noticeable difference. But if your heating bill is high for other reasons (poor insulation, leaky windows, inefficient furnace), a new door alone won't fix that. Get a real assessment of where your heat loss is actually happening before you drop thousands on a door replacement.
How long does a professionally installed door last in Vancouver's climate?
Fiberglass or steel doors can last 20-30 years with minimal maintenance. Wood doors need more care but can last just as long if properly finished and maintained. The bigger variable is installation quality — a perfectly good door installed poorly will fail in five years, while a mid-range door installed correctly can outlast it by decades.
