Window And Door Repair Markham

Window and door repair services involve fixing the glass, screens, moving parts, and locking components that help a property stay secure, efficient, and easy to use. In Markham, that can mean replacing foggy glass in a family home, handling a window crank replacement in a condo, or restoring a busy commercial entrance for a storefront or office.

For many property owners, the smartest solution is not full replacement. It is targeted repair. At Revitalize Windows & Doors Inc, we focus on saving customers time and money by repairing instead of replacing whenever the existing frame or door can still be revitalized. Our mobile team serves homeowners, property managers, and general contractors across Markham, Toronto and the GTA with practical, professional service.


Window glass repair and replacement focuses on the glass unit itself rather than the full frame. This is often the right answer when the frame is still stable but the glass is cracked, broken, or fogged between panes.

In many Markham homes and condo units, we see sealed unit failure in double-pane windows. That is when moisture gets trapped between the panes and creates a cloudy or foggy appearance. We also handle broken glass, cracked panes, and glass replacement for windows that no longer insulate properly.

Our glass replacement Markham service is ideal when you want to restore visibility, energy efficiency, and comfort without paying for a full new window. This approach saves time, reduces waste, and keeps the repair focused on the part that actually failed.

Common reasons to repair or replace window glass include:

visible damage after impact or weather exposure

foggy glass caused by seal failure

cracked or shattered panes

drafts related to failed glass units

condensation trapped inside insulated glass

Window screens are the mesh barriers that let fresh air in while helping keep insects out. Over time, they can tear, loosen, bend, or pop out of place. This is especially common in homes with pets, children, frequent seasonal use, or older aluminum frames.

A damaged screen may seem minor, but it affects comfort and ventilation. For Markham homeowners, property managers, and contractors finishing repairs or turnovers, replacing a torn or sagging screen is a simple way to improve usability right away.

We repair and replace window screens for many common window styles, including casement, awning, sliding, and hung windows. If the frame is bent beyond reuse, we can replace the full screen assembly. If the mesh is the only issue, a rescreen may be all that is needed.

This service helps you avoid replacing the whole window when the problem is only the screen.

Window hardware includes the mechanical parts that allow the window to open, close, lock, and seal properly. This category covers some of the most common requests for window repair Markham customers call us about.

A casement crank is the handle and internal operator that pushes a casement sash open and pulls it closed. If the handle spins, slips, or stops moving the sash, the operator may need repair or replacement. A hinge arm is the metal support that guides the sash as it opens. If it bends, rusts, or pulls the sash out of alignment, the window may drag or stop locking properly. Locks and keepers also wear out, which can affect both security and weather sealing.

We regularly handle:

  • window crank replacement
  • casement operator replacement
  • hinge repair and hinge replacement
  • lock and keeper replacement
  • awning and casement hardware service
  • adjustments for windows that no longer close evenly

In many cases, replacing the failed hardware restores smooth operation without touching the frame. That is a major cost advantage compared to full replacement.

Sliding patio doors often become difficult to use because of worn hardware, not because the whole door has failed. The most common issue is bad rollers. Rollers are the wheel assemblies at the bottom of the sliding panel that help the door glide along the track. When they wear down, the door becomes heavy, noisy, difficult to slide, or unsafe to operate.

We also replace broken handles, damaged mortise locks, keyed locks, and other patio door parts. For many customers searching for patio door roller replacement, the goal is simple: make the door slide smoothly again without the cost of replacing the entire unit.

Signs your patio door hardware may need service include:

  • the door drags or feels extremely heavy
  • the handle is loose or broken
  • the lock does not engage properly
  • the panel jumps off alignment
  • you need to push or pull hard to open the door

For Markham homes, condos, and rental properties, this repair can make a big difference in day-to-day use while keeping costs under control.

Screen doors provide ventilation and insect protection for patios, balconies, and rear entrances. We service both sliding screen doors and retractable screen systems in Markham.

A sliding screen door uses rollers to move along its own track. When those rollers wear out or the frame bends, the screen door may drag, stick, or fall out of alignment. A retractable screen door uses a spring-loaded mesh system that pulls across the opening and retracts into a side housing when not in use. If the mesh tears or the mechanism stops tracking properly, the unit becomes frustrating to use.

We repair and replace:

  • sliding screen door rollers
  • sliding screen door handles and latches
  • damaged screen mesh
  • bent screen door frames
  • retractable screen components where serviceable
  • full screen door units when repair is no longer practical

This is another area where repair-first service can save money and quickly restore airflow and convenience.

Commercial doors need dependable hardware to handle traffic, maintain security, and support safe access. In Markham plazas, offices, condo common areas, and commercial buildings, worn door hardware can quickly become a safety issue or operational headache.

A door closer is the hydraulic device mounted at the top of a commercial door that controls the closing speed. An exit device is the panic bar or push bar that allows fast exit from inside. When these parts fail, the door may slam, stay open, fail to latch, or stop functioning safely.

We work with property managers and general contractors on hardware including:

  • door closers
  • commercial locks and cylinders
  • deadbolts
  • exit devices and panic bars
  • push paddles
  • pull handles
  • hinges and related door hardware

Repairing or replacing the correct hardware is often far more efficient than changing the whole door. It also helps maintain security and keeps the entrance functioning the way it should.

Storefront glass is the glass used in commercial entrances, display windows, and aluminum-framed business façades. When that glass is cracked, broken, or compromised, the issue affects security, appearance, and business operations right away.

Our storefront glass repair service helps Markham businesses address damaged glass quickly and professionally. We work on commercial glass panels and related glazed sections where replacement of the affected glass is the practical solution.

This service is commonly needed for:

  • cracked storefront glass
  • broken commercial door glass
  • damaged fixed glass panels
  • impact-related glass replacement
  • restoring a clean, professional exterior appearance

For business owners and property managers, timely storefront glass service helps protect the premises and keeps the property looking well maintained.
