Can you fix drafts and leaks around a sliding door?

Yes. We adjust the sill height, replace sweeps and weatherstripping, seal gaps and align the panels.

Should I repair or replace my sliding door?

Repair first in most cases. Replacement makes sense when the frame is badly damaged, the sealed glass has failed (fogging between the panes), or you want better efficiency, security or style.

Do you work evenings and weekends?

Regular appointments are Monday to Friday, 8 am to 5 pm. For emergencies, such as a door that won't lock, we're available 24/7.

Try This First

If your sliding door just feels stiff, vacuum the bottom track and wipe it with a damp cloth. Dirt in the track is the most common cause of a sticky door. If it still drags or jumps after cleaning, the rollers are probably worn, and it's time to call us.

Pricing and How It Works

Minor patio door repairs (rollers, track tune-ups or a new lock) usually cost $120 to $350 plus parts. The service call is $65 and is waived when we complete the repair.

Call us: we ask about the problem and give you a price range.
Diagnosis: the technician confirms the cause on site and gives you the exact price.
Repair: same-day repair and a full tune-up of the door.
Final check: we test the door, lock and seal. Roller replacements carry a 1-year warranty.

If repair isn't cost-effective, we'll tell you and quote a replacement.

Frequently Asked Questions

Grinding, a door that drags or bumps, or a door that won't stay where you leave it are the usual signs. If cleaning the track doesn't help, new rollers and an alignment will.
