Sliding Door Threshold & Sill Repair

The threshold, or sill, is the track your door actually rides on, and it takes the most abuse from foot traffic and water. A damaged sill causes problems no roller adjustment will fix.

Signs Your Sill Needs Attention

Visible cracking, corrosion, or pitting in the track surface
Water pooling at the threshold after rain
A soft or spongy feel underfoot near the door
The door catches on a specific point in the track every time

What's Included

We repair or replace the damaged sill section, reseal the transition to your flooring, and confirm the new surface is level and smooth for the door to ride on.

Water Intrusion Is Common Here

Heavy Florida rain finds any weakness in a worn sill. Addressing it early prevents water damage from spreading to subflooring or interior finishes.

How It Works

1. We inspect the threshold and sill for water intrusion, rot, or a worn track channel.
2. We repair or replace the threshold and sill.
3. We reseal and confirm water drains away from the door, not into your home.

FAQ

Is a damaged threshold why water gets in when it rains?

It's one of the most common causes, yes. A worn or improperly sloped threshold lets wind-driven rain track into the house.

Can this be done without removing the whole door?

Usually yes, threshold and sill repair can typically be done with the door panels still in place.
