We repair and replace windows, doors and glass across Bowmanville, Courtice, Newcastle and Clarington, from failed window components to damaged residential and commercial entrances.
For an entry door that binds in Bowmanville, Courtice or Newcastle, we check the hinge side and strike alignment before deciding which adjustment is needed. The cause is confirmed at the opening.
We also replace rusted or crushed rollers in heavy sliding patio doors, upgrading them to precision steel bearings so they glide with ease.
Condensation trapped between the panes can indicate a failed insulated glass unit (IGU). We can replace that unit while keeping a serviceable frame. Moisture on the room-side surface needs a separate assessment.
If your windows won't open or lock properly, we carry replacement casement cranks, operators, and latches for most major window brands.
If a closed window or door in Clarington feels drafty, we separate the moving seals from the exterior caulking joint during inspection. We then quote the area that needs repair.
We also look for poor closing or a gap that new sealant would not fix. The repair recommendation depends on those checks, rather than a promise that caulking alone will stop every leak.
We service residential locks and commercial exit hardware as well as insect screens. For commercial double doors, tell us whether one leaf drags, closes too fast or fails to latch.
Our Clarington commercial project used double steel doors with two door closers. We review how both leaves close and latch; these closers control door movement and are not automatic opening operators.

We replace shattered patio door glass, custom sidelites, and commercial storefront panels across Clarington.
We identify whether the damaged panel is in a door, a window or a storefront, then confirm a suitable replacement specification. Permanent glass timing depends on that specification and supply.
High winds and unexpected accidents cause glass breakage. Our Clarington emergency team is available 24/7 to secure your home or business.
We assess the damaged opening, remove accessible glass hazards as part of the agreed work and arrange temporary securing where needed. Measurements and the permanent replacement schedule follow that assessment.

Start with the affected opening: these checks help identify the repair or replacement service you need.
Fog between panes does not by itself require a complete window. We check the sash and frame, then measure the sealed unit and review suitable replacement glass options.
Window glass replacementAn operator retrofit needs a compatible door, frame, controls and power arrangement. We review the complete Clarington entrance before planning installation and operational testing.
Automatic door operatorsReplacing a slider with hinged garden doors changes the opening layout and swing space. We measure those details and review glazing, threshold and locking arrangements before installation.
French and garden doorsInspect perimeter seals and door alignment when an opening leaks air. Grit in a patio track, worn rollers and torn insect screens can be checked as separate maintenance issues.
Weatherstripping and caulkingOur Clarington double-steel-door project is a local example of commercial entrance and closer work. We also provide residential window, door and glass services, with the repair recommendation based on the inspected opening.
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.
