Drafty Door

Sliding doors seal against the weather with a few unglamorous parts: the fuzzy weatherstripping (often called brush pile or fin seal) along the edges where the panels meet and slide, and the gaskets and sweeps around the frame. These wear out. The brush pile gets crushed and flattened over years of sliding, and the rubber gaskets dry out, crack, and shrink under constant UV exposure. Once they've degraded, air slips right through the gaps.

Alignment is closely tied to drafts. If the door has sagged on worn rollers or sits crooked in the frame, the panels no longer close tightly against each other or against the jamb, leaving a gap you can sometimes see daylight through. So a drafty door and a hard-to-slide door often share the same root cause - a door that's dropped out of square - and correcting the alignment closes the gap while also improving how it slides.

In Central Florida a leaky door is mostly a comfort and energy problem rather than a winter-cold one. Hot, humid outside air infiltrating around a poorly sealed door makes the room near it feel warm and sticky, forces your AC to run longer, and can even let more moisture in. Sealing the door up tight is one of the easier wins for keeping a room comfortable and your cooling costs in check through the summer.

We check where the air is actually getting in - worn weatherstripping, failed gaskets, or gaps from misalignment - and replace the seals with fresh weatherstripping sized to your door, then adjust the door so it closes snugly. It's a modest repair that makes a noticeable difference in comfort right by the door, and it protects the interior from the humidity trying to push its way in.
