Here’s a clear, practical breakdown of the steps involved in fitting aluminium sliding doors.
1. Measure and Prepare the Opening
Before installation, accurate measurement is critical. Your wall opening should:
Match the door system dimensions exactly
Be square, level, and structurally sound
Be free of debris, old fixings, or moisture
Use a spirit level and measuring tape to confirm the dimensions. If the wall isn’t level or requires adjustments, resolve these first—don’t rely on the door frame to correct building issues.
2. Install the Bottom Track
The bottom track supports the weight of the sliding panels and guides movement.
Place the bottom track into the opening.
Use packers to level the track precisely.
Drill pilot holes, then secure the track with appropriate screws or anchors.
Apply waterproof sealant beneath the track to prevent leaks, especially for external doors.
Ensure the track is completely level end-to-end—any tilt will affect the door’s glide and alignment.
3. Fix the Frame in Place
Now assemble the full aluminium frame:
Attach the side jambs to the bottom track.
Fit the top track across the top, completing the rectangle.
Fix the frame into place using screws and wall plugs or anchors.
Double-check squareness using a diagonal measurement method (cross-corner measuring).
Apply a silicone seal between the frame and wall edges for a tight, weatherproof finish.
4. Hang the Sliding Panels
Aluminium sliding doors usually come with pre-installed rollers and handles. To fit them:
Lift the panel at an angle and place the top into the upper track.
Gently lower the bottom onto the bottom track.
Adjust the rollers to raise or lower the panel for alignment.
Repeat for any additional panels, depending on your door configuration.
Test each panel to ensure smooth operation.
5. Install Locks and Seals
Attach locks and handles according to the manufacturer’s guidelines.
Align the locking system with the jamb or adjacent panel for a secure close.
Fit weather seals or brushes to reduce noise, dust, and draughts.
Some aluminium door systems also come with interlockers between panels for added stability and security.
6. Final Checks and Adjustments
Once everything is in place:
Slide each panel back and forth fully to check for friction or misalignment.
Fine-tune the roller height if needed using the adjustment screws.
Inspect seals for gaps and reseal any problem areas.
Clean off any fingerprints, stickers, or sealant overflow.
A well-installed aluminium doors system will glide effortlessly, lock securely, and resist moisture and wind for years.
Tools You’ll Need
Drill and bits
Level and measuring tape
Screwdrivers
Silicone sealant
Packers or shims
Allen keys (for roller adjustments)
Gloves and safety glasses
When to Hire a Pro
Call a professional if:
You’re unsure about structural integrity
The opening requires major adjustment
The door is oversized or unusually heavy
Compliance with local regulations is unclear
Incorrect installation can lead to poor insulation, water leaks, and even door failure—especially in external setups.
Conclusion
Installing aluminium sliding doors is a rewarding upgrade that enhances both functionality and style. With the right preparation and careful execution, you can enjoy expansive views, easy access, and improved comfort—all while adding value to your property.
