Old sliding doors often stick, let in drafts, and fail to lock securely. These problems affect both comfort and safety in the home. A well-made patio door and proper installation can solve these issues by improving insulation, security, and ease of use.
In this guide, we explain the full patio door installation process. You’ll learn how we remove the old unit, prepare the opening, and install the new door with the right seal and finish to ensure long-term performance.
Why Your Old Patio Door Is Not Working
Most people already have a sliding door. But that does not mean they like it. A lot of the old ones barely slide, feel drafty, and are hard to secure. Here are some of the most frequent problems we see:
- Rollers get stuck or break
- Door becomes hard to open or close
- Cold air comes in during winter
- Sunlight makes it too hot in summer
- Weak locks or no outside access with a key
Key Takeaway: If you need a broomstick to keep your patio door closed, it is time for an upgrade.
Steps We Follow To Install Your New Patio Door
First Step: Removing the Old Door
We begin by carefully taking out the old door. This includes cleaning the space and checking for any damage around the opening or sill.
Second Step: Preparing the Opening and Placing the Frame
We make sure the opening is level and square. Then we:
- Fit the new frame into place
- Use shims and sealants to make sure it seals tightly
- Prepare it for the glass panels
Third Step: Installing the Glass Panels
Our doors use triple-pane glass. That means they are heavier than normal, so we use stronger rollers. These heavy-duty rollers make the door glide open and close with very little effort.
Pro Tip: Even with the heavier glass, our doors are smooth enough for a child or older adult to use easily.
Final Step: Sealing and Finishing
Once the door is installed, we:
- Seal every edge to keep out air and water
- Attach trim that matches your room style
- Check the lock to make sure it works perfectly

How Our Patio Doors Improve Comfort and Safety
Stronger Security Features
Our doors use a three-point locking system that secures the top, middle, and bottom. All locks are controlled with one handle. You can also unlock it from the outside with a key.
This is much better than the old hook-and-latch locks that are easy to break.
Better Insulation for Summer and Winter
Older doors often let in cold drafts or heat. Our triple-pane glass and tight seals fix that. You can now sit next to your patio door, no matter the season.
Key Takeaway: Our doors add usable space inside your home because they are not too hot or cold to sit near.

Our patio doors come in many colors and designs. You can choose:
- Internal blinds for privacy
