Weatherstripping and Brush Seals If you can feel the wind, the seals are done.
Sliders seal with rows of brush pile along the edges and where the panels meet. When the pile flattens or pulls loose, wind and rain come through the gaps.

Signs the seals have failed
Pick a windy afternoon and run your hand along the edges of the closed door. You’ll find the gap.
Send us a photo so we come with the right parts.

What we do
What we replace and adjust
-
Brush pile
We pull the old pile out of its slots and slide in new pile with the right backing width and height. Pile with a thin plastic fin down the middle blocks wind better than plain pile.
-
Interlock seals
Where the two panels hook together, worn seals and bumpers are replaced so the panels close tight against each other.
-
Weep holes
We clear the drain slots in the sill, so rain that gets into the track drains back outside.
-
Square the panel
A seal only works if the panel meets it. We set the panel square and at the right height so it closes evenly along the jamb and the interlock.
Pile size matters
Brush pile, also called wool pile, comes in a lot of backing widths and pile heights. The backing has to fit the slot in your door. The pile has to be tall enough to touch the surface it seals against, but not so tall that it drags. Too short leaves a gap. Too tall makes the door hard to push and wears out fast. So we measure the slot and the gap before we cut anything.
Water in the track isn’t always a leak
Sliding door tracks are built to catch some water in a heavy, wind-driven rain and drain it out through weep holes at the front of the sill. A little water in the track during a storm is normal. Water that stays there after the rain stops, or spills onto your floor, means something’s wrong. Usually the weep holes are blocked, or the seals at the bottom of the panel and at the interlock have worn out.
Before hurricane season: clear each weep hole with a pipe cleaner, then pour a cup of water into the track and watch it drain. If it doesn’t, book a free estimate.
What we don’t do
We don’t replace glass or install new doors. We fix the one you have.
We replace the door’s own seals and clear its drains. Leaks through the wall or around the outside of the frame come from the building, not the door, and that’s not work we do. We’ll tell you if that’s what we find.

FAQ
Weatherstripping & seals: straight answers
How much does new weatherstripping cost?
Every door is different, so we don’t guess over the phone. A specialist looks at your door and gives you an exact price, free, before any work starts.
No quotes over the phone, by text or by photo. Several doors? Ask about multi-door savings.
Why does my sliding door whistle when it’s windy?
Wind is getting through a gap, most often at the interlock where the panels meet or along the lock side of the frame. Flattened pile, or a panel that has shifted out of line, is the usual cause.
Can you fix a slider that leaks when it rains?
If the water comes through the door, yes: that’s seals, weep holes or adjustment. If it comes through the wall or around the outside of the frame, it’s a building problem. We’ll tell you, so you know which trade to bring in.
Can I replace the weatherstripping myself?
Some pile can be changed without taking the panel out, but most of it runs in slots you can only reach with the panel removed. The harder part is getting the right size. Close enough usually isn’t.
Will new seals help with bugs?
Yes, if the bugs are coming in around the door. Worn pile along the bottom and edges is a common way in for ants and no-see-ums. It won’t help with a torn screen, but we fix those too.
