Weatherproofing

Sliding Door Weatherstripping & Seal Replacement

Worn weather seals let in drafts, water, and bugs, and let your conditioned air escape. We replace bottom rails, pile weatherstripping, and door sweeps to seal your sliding door back up.

Signs Your Seals Need Replacing

Air movement or a draft around a fully closed door
Water on the floor near the door after heavy rain
Visibly worn, torn, or missing weatherstripping
A noticeably higher cooling bill with no other explanation

What's Included

We replace the bottom rail seal, pile weatherstripping along the frame, and door sweeps as needed, addressing the specific point where air or water is getting through, not just applying a generic fix.

Especially Relevant in Florida

Heat, humidity, and storm-driven rain put more stress on seals here than in drier climates. This is worth addressing before hurricane season, not after.

What We Inspect

Bottom rail seal condition
Pile weatherstripping along the frame for gaps or wear
Door sweep condition at the threshold
Where air or water is actually entering, not just general wear

Repair vs. Replacement

Weatherstripping is a replace-not-repair component, once the pile or bottom seal is compressed or torn, it's swapped for new material sized to your door's channel. The only judgment call is whether the frame underneath is also compromised, which we check while the old seal is off.

Our Process

1. Identify the exact point where air, water, or bugs are getting through
2. Remove the worn bottom rail seal and pile weatherstripping
3. Fit new seals matched to your door's channel size
4. Replace the door sweep if worn
5. Test the seal by closing the door and checking for light or air gaps

Common Questions

How do I know if it's the weatherstripping and not the frame?

If the draft or leak follows the frame edge evenly, it's almost always the seal. A leak concentrated at one spot more often points to a frame or sill issue, we check both.

Does new weatherstripping really lower cooling bills?

On a frequently used sliding door with visibly worn seals, yes, it's one of the better-value comfort upgrades we offer.

How long does weatherstripping last in Florida?

Typically several years, but heat and UV exposure degrade it faster here than in milder climates, so check it annually.
