Another Episode of BAD INSTALLS – How NOT to Install a Sliding Glass Door

I see this all the time—and yes, it leaks, binds, and eventually fails.

A single 5' x 10' hurricane-rated sliding door panel weighs 500 pounds. That’s over 1,000 PSI on the rollers. If the track isn’t fully supported, it will sag between shims, and the panel will rock with every movement.

One client described it perfectly after I pointed it out:

“It looks like a cow galloping down the road.”

This isn’t just about smooth operation—it’s about water intrusion, long-term durability, and holding everyone accountable.

✅ The proper install:

• Laser-leveled track

• Continuous grout pour

• Set in a full bed of sealant

You need this written into contracts with your window dealer and enforced in the field. Yes, it costs more—but it’s non-negotiable if you want it done right.
