We provide window and door repair, replacement glass and complete window or door installation across Ajax, including patio systems and commercial entrances that need adjustment, repair or replacement.
We install and replace front entry and patio doors in Ajax when the existing system is damaged, outdated or no longer seals and operates properly.
Where the door can be restored, we replace worn rollers, cap damaged tracks, realign hinges and strikes, and correct locking problems.
We install and replace windows in Ajax when frames, sashes or complete units have reached the end of their useful life. When the frame is still sound, we can often replace only the failed insulated glass unit.
We also replace stripped cranks, broken operators and faulty sash locks, then adjust the opening for a tighter seal.
For an Ajax opening that lets in air or water, tell us where you notice the problem and whether it happens with the window closed. We inspect the sealant joint, weatherstripping and frame fit.
We renew the sealing material that has failed and check how the opening closes. Recaulking cannot correct every leak, so we explain when the source needs further investigation.
Upgrade your home’s security with premium handlesets, high-security deadbolts, and properly adjusted multi-point locks.
For businesses in Ajax’s commercial zones, we repair commercial aluminum door closers, pivots, and panic bars to ensure reliable, safe access.
We replace broken window, patio-door, sidelight and storefront glass. For safety glazing, we confirm the opening and required glass specification before the panel is ordered.
We replaced a large commercial window panel for an Ajax restaurant. A full-opening photo helps us distinguish a fixed storefront pane from door glass before arranging measurements.

After the opening is secured, we measure or arrange a measurement visit for the permanent glass. We confirm product availability and access requirements before giving an installation date.

Start with the affected opening: these checks help identify the repair or replacement service you need.
A patio door that drags needs its rollers and lower rail checked together. Where the door remains serviceable, replacement rollers or a fitted track cap can restore movement.

I hired DoorWin services to replace two cracked glass windows for a unit at my triplex. An exterior porch window and interior stairwell window I just needed the panes of glass replaced and not the entire frame . DoorWin was happy to do the job. Unlike some other companies who wanted to replace the entire frame at a higher cost. They were very quick with a quote and were able to perform the job on an extremely tight timeline that I had to unexpectedly move up. Very professional. Friendly. Dependable. Competitive prices. Took away all materials and left a clean worksite. Would highly recommend and will work with them again if I need another window repair.
Max at DoorWin completed a professionally executed job on our front door while being a pleasure to deal with...would recommend him for any services their company provides.
