Sliding Door Won't Close Flush or Letting in Drafts?

What Causes Gaps and Drafts

• Worn, cracked, or missing weatherstripping around the frame
• The door has shifted out of alignment on the track
• A warped frame from years of Florida's heat and humidity
• A damaged or bent track that stops the door from closing fully
• Foundation or frame settling over time

How to Tell What's Letting the Draft In

• You can see daylight around the edges when the door is closed
• The weatherstripping looks cracked, flattened, or is missing in sections
• The door closes but doesn't sit flush against the frame
• The draft is worse after storms or high winds, suggesting frame movement

Sealing Out Drafts, Bugs & Water

We start by checking whether the door is closing flush against the frame. If it's an alignment issue, we adjust the rollers and track so the door seats correctly. If the weatherstripping is worn, cracked, or missing, we replace it to restore a tight seal against air, water, and insects.

If the frame itself is warped or the track is damaged, we'll walk you through what's needed to fully close the gap, sometimes a repair, occasionally a replacement if the frame is beyond adjustment.

Can You Fix a Drafty Door Yourself?

Replacing visibly worn weatherstripping is a reasonable DIY project if you can find a matching profile for your door brand. But if the door itself isn't sitting flush, no amount of new weatherstripping will fully seal it, the alignment has to be corrected first. If you've replaced the seal and the draft persists, that's a sign the real issue is alignment, not the weatherstripping.

What to Expect When We Come Out

We check whether the door is closing flush against the frame and inspect the weatherstripping along the full length of the door. If it's an alignment issue, we adjust the track and rollers; if the seal is worn, we replace it. Either way, we confirm the seal is complete before we leave.

Why Central Florida Homeowners Call Bayfront

A door that doesn't seal properly works against your air conditioning around the clock. Catching this early, often through routine maintenance, is far cheaper than the energy loss adds up to over time. Catching a drafty door during a routine maintenance visit is almost always cheaper than the energy cost of ignoring it for a full Florida summer.
