Quick answer

Is this the right door service?

Here is what customers usually need to know before calling or sending photos.

Use this service when

  • Commercial doors dragging, rubbing, slamming, drifting open or failing to latch cleanly.
  • Storefront, aluminum, hollow metal and back-of-house doors with worn pivots, hinges, closers, strikes or lock alignment problems.
  • Business entrances that need repair-level service rather than a full storefront rebuild or glass-only replacement.

What DoorWin checks or does

  • Commercial door system diagnosis covering slab, frame, pivots or hinges, closer, threshold, lock side and strike engagement.
  • Repair-versus-replacement guidance based on security, traffic, hardware compatibility and the condition of the existing opening.
  • Operational testing after service so the door closes, latches and handles daily customer or staff use more reliably.

Real project walkthrough

Commercial Door Replacement Process — Real DoorWin Project

This Mississauga project shows how DoorWin handles a worn exterior commercial entrance from old door inspection through frame removal, opening preparation, new door installation, panic hardware, closer adjustment and final sealing.

Old exterior commercial door before replacement in Mississauga
Step 1

Inspect the old exterior commercial door

The existing entrance showed weather wear, staining near the bottom, rust around the threshold and an aging frame. This is the kind of issue people often search for as commercial door replacement, exterior commercial door replacement, business entrance door replacement or commercial entry door repair.

Step 2

Check inside hardware, panic bar and closer

From the interior side, the door had panic hardware and a surface closer. The replacement needed to keep safe exit function while improving the door slab, frame fit, closing action and overall entrance reliability.

Old commercial door frame removed before new entrance installation
Step 3

Remove the existing door and frame

DoorWin removed the old door system and frame components so the opening could be measured and prepared correctly. This is the commercial door frame replacement stage of the job, and it is often needed when the issue is more than a closer or lock adjustment.

Step 4

Clean and prepare the rough opening

The opening was cleared, checked and prepared for the replacement system. Proper opening preparation helps prevent future rubbing, latching problems, water gaps and uneven reveal spacing.

Step 5

Prepare the new commercial door

The new wood-grain commercial door with a narrow vertical glass lite was prepared for installation. This style keeps a professional business entrance look while supporting visibility and controlled access.

Step 6

Set, level and align the new door

The new entrance was positioned and aligned in the opening. At this stage, reveal spacing, swing clearance, threshold contact and hardware position are checked before the door is permanently finished.

Step 7

Seal, adjust and test the finished entrance

After installation, the door was sealed, the panic hardware and closer were checked, and the entrance was reviewed for smooth closing, proper latching and a clean commercial finish.

I’m very satisfied with my experience with this company! True professionals work here — everything was done quickly, efficiently, and with great attention to detail. The staff are very polite, kind, and pleasant to deal with. The prices are more than reasonable, especially considering the high level of service — everything is top-notch. I had a broken window, and they handled the job perfectly. What impressed me even more is that they came at night when other companies refused to help. Highly recommend!
