Sliding door installation: a guide for pros

What customers ask, how to win the job, and what to put on your profile.

Offering sliding door installation

Sliding door installation is a track and roller job where the level of the sill and the alignment of the panels decide whether the door runs smoothly and seals tight. Your win is a level track, adjusted rollers and a door that closes and locks every time.

What customers ask

  • Will the door slide smoothly after the install?
  • Can you replace the rollers without replacing the whole door?
  • Will the drafts stop at the meeting rail?
  • How do you keep the panel from jumping the track?
  • Can you install a barn-style door on my interior wall?
  • What warranty covers the glass and the rollers?

How to win the job

  • On the first call, ask for the door size, the panel count, the frame condition, and whether the door sticks, leaks or jumps, so you bring the right rollers and track.
  • Bring a sample of the roller and the weatherstrip to the visit, and show the homeowner how the roller adjusts.
  • Check the sill level, the track and the frame on the site visit, and photograph any rot, bent track or cracked glass before you quote.
  • Put the door type, track, rollers, weatherstripping, lock and any sill repair in the quote as separate lines.
  • Explain the roller adjustment and why the sill has to be level, so the homeowner understands the repair.
  • Test the glide in both directions, the lock and the seal before you leave, and show the homeowner the result.
  • Send a closeout packet with the door product name, the roller and track details, the glass type and the warranty papers.

What to put on your profile

  • Photos of finished sliding door installs that show the track, the roller and the meeting rail seal
  • Sliding door types you install, such as glass sliders, patio doors and barn-style doors
  • Track and roller systems you install, including heavy-duty options
  • Service area and whether you handle sill repair and framing for sliding doors

Follow-up that helps the customer

  • Offer a roller and track cleaning every year, to keep the glide smooth and the seals in good shape.
  • Suggest a weatherstrip replacement along the meeting rail as the seal ages.
  • Recommend a sill and frame check after heavy rain, to catch water that is getting into the sill.

Licenses and permits

Sliding door installation is commonly done by licensed window or door contractors, and rules vary by place. Check your state and local licensing requirements before you bid, including permits for opening, sill or framing changes.

Questions

Do I need a permit to install a sliding door?

Often not for a like-for-like swap. Enlarging an opening, cutting a new one or changing the framing usually needs one. Check with the local building office before you quote.

How do I handle a sill that is out of level?

Stop, measure it, and show the homeowner the gap. Recommend a sill repair or a shim plan as a separate line, and do not force the track level with the rollers.

Can a barn-style door be hung on a wall without a header?

Only if the wall and the framing can carry the track and the door's weight. A pro should check the wall and the framing before anything is mounted.
