Foggy window glass, failed hardware, a damaged entry door or storefront problem? We provide repair, replacement and installation options for Mississauga homes and businesses, with emergency help available when an opening cannot be secured.
For a storefront left exposed, a commercial door damaged after a break-in, or a door that will not lock in Mississauga, the first job is to secure the opening before planning the permanent repair.
Recent local proof includes the commercial entry near Tomken Rd and Burnhamthorpe Rd E, where the job moved from emergency securing to a proper replacement door and hardware path.
Most Mississauga window repair calls start with one of four symptoms: fog between panes, a crank that spins without moving the sash, a lock that no longer pulls tight, or a draft around a frame that is still worth keeping.
Our Mississauga renovation project shows a new vinyl window installation. For an existing opening, we first check whether a failed glass unit or moving component can be replaced while retaining the frame.

Door repair in Mississauga covers commercial entry doors, storefront doors, front entry doors and patio sliders that drag, slam, fail to latch or were damaged after forced entry.
We check the whole opening before recommending parts: door slab, frame, hinges, closer, lock side, threshold, weatherseal and any glass-adjacent damage around the entrance.
We supply and install custom replacement glass for shattered condo balcony doors, broken sidelites, and commercial properties.
We confirm whether the opening needs an insulated unit, tempered panel or laminated glass. The order follows the measured size, opening type and suitable safety specification.
Secure your family home or business with upgraded deadbolts, handlesets, and high-security multi-point locks.
For our commercial clients, we routinely service heavy-duty door closers, pivots, and panic bars to keep high-traffic entrances accessible and safe.
For a Mississauga door or window that still has a usable frame, we inspect weatherstripping, exterior joints and closing fit. The quote identifies the seal or adjustment proposed.
A new seal should work with the hardware already holding the opening shut. We check the latch, hinge or operator where uneven fit is contributing to the gap.

Start with the affected opening: these checks help identify the repair or replacement service you need.
Cloudiness between panes may indicate a failed sealed unit. We measure replacement glass after checking that the sash and frame can remain in place.
Window glass replacementThe frame, strike, hinges and closer need inspection alongside the lock. Our commercial entry work in this area shows why the complete opening matters when planning the repair.
Commercial door repairA slamming door is a symptom, not a confirmed closer diagnosis. We check closer condition, settings, alignment and other entrance components before recommending the repair.
Slamming door diagnosisHeavy balcony-door movement needs a track, roller and lock check. For City Centre properties, confirm building access arrangements before the visit; glass and seal issues are assessed separately.
Sliding patio door serviceOur Mississauga work includes renovation window installation, storefront glazing and commercial entrance repairs. We assess glass, frames and working hardware together where they affect the same opening, then explain a focused repair or replacement scope.
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.
