Steel vs Fiberglass Entry Doors: Which One is Better?

Sliding patio doors are a staple in many Canadian homes, offering natural light, easy access to the backyard, and a beautiful view of the outdoors. But when it’s time for an upgrade—whether due to wear, drafts, or design changes—removing the old sliding door is the first step in your renovation journey.

At Royal City Windows & Doors, we help Ontario homeowners transition to newer, more efficient door systems every day. Here’s how to safely and effectively remove your sliding patio door like a pro.

Tools You’ll Need

  • Flat-head and Phillips screwdrivers
  • Power drill (optional)
  • Pry bar or crowbar
  • Utility knife
  • Safety gloves and glasses
  • Putty knife
  • Tarp or drop cloth

Steel entry doors are a popular option for homeowners looking for durability and protection because of their strength, affordability, and ease of maintenance.

Step-by-Step: How to Remove a Sliding Patio Door

Prepare the Area

Start by clearing the space around the door, both inside and outside. Lay down a drop cloth to protect your floors and gather all your tools in advance.

Remove the Sliding Panel

  • Unlock and open the sliding portion of the door.
  • Lift it upwards into the top track and pull the bottom out from the bottom track.
  • If the door won’t come out easily, locate and remove any adjustment screws at the bottom to lower the rollers.

Pro Tip: These panels can be heavy—always lift with assistance if needed.

Remove the Stationary Panel

  • Locate the bracket or screws holding the stationary panel in place, usually along the top or side.
  • Unscrew and carefully pry the panel away from the frame.
  • Gently slide it toward the center and lift it out.

Detach the Frame

  • Use a utility knife to cut any caulking or sealant around the door frame.
  • Remove screws or nails anchoring the frame to the wall studs.
  • With a pry bar, carefully loosen and pull the frame from the rough opening.

Clean and Inspect the Opening

Once the frame is out, inspect the area for moisture damage, gaps, or rot. This is a perfect opportunity to make any necessary repairs or upgrades to insulation before installing your new patio door.

FAQs

Can I remove a sliding patio door myself?

Yes, but only if you’re comfortable with basic tools and minor demolition. Sliding doors are heavy and require care to remove safely. For complex cases, professional help is always recommended.

How long does it take to remove a patio door?

Typically, removal takes 1–2 hours, depending on the door’s age, size, and installation method. Additional time may be needed if there’s water damage or structural issues.

Do I need a permit to replace patio doors in Ontario?

Generally, no permit is needed for door replacement if the opening size remains the same. However, any structural changes (like widening the opening) may require a permit. Always check with your local municipality.
