You’ve picked the new door and booked the installer, so the hard part is done. Mostly. What happens in the days before installation can decide whether the job takes a morning or drags into a second visit.
A little preparation makes the door installation Perth homeowners book run faster, cleaner and with fewer surprises on the invoice. Here’s what to sort out before the van pulls up.
1. Confirm the Door, the Opening and the Frame
Start by being clear about what’s going in. A sliding glass door relies on a level track and good rollers. A hinged entry door depends on a solid frame, hinges and locks that suit its weight.
Final measurements should come from the installer, not your tape measure, especially for made-to-measure doors. Ask whether the existing frame is staying or being replaced. A new door hung in a twisted or rotting frame won’t seal or lock properly, and fixing it on the day costs more than planning for it.
2. Check What the Quote Includes
A door is only as good as its hardware. Before installation day, make sure your quote spells out:
-
The lock type, handles and number of keys
-
Hinges or rollers and track
-
Weather seals and the threshold
-
Removal and disposal of the old door
-
Any frame repairs or trim work
A reputable Perth window and door replacement company will put all of this in writing. If you’re adding a security screen, ask for evidence that it’s tested to AS 5039.1:2023 rather than relying on words like “heavy-duty”.
3. Ask About Approvals Early
Swapping a door within the same opening is normally straightforward. Turning a single hinged door into a wider sliding door is a different job, because it can mean altering the wall and the support above it. If the opening is changing, or the home is strata-titled or heritage-listed, confirm requirements with your local council or strata manager before anything is ordered.
4. Clear the Space and Protect Your Floors
Installers need room to work safely. Ask how much clearance they need, then clear both sides of the doorway: rugs, shoe racks, pot plants, side tables and any cables.
Large glass sliding panels are heavy and awkward, so the path from the driveway matters too. Lay down protection over timber floors and take framed pictures off nearby walls, since drilling can shake them loose.
5. Sort Out Access, Pets and Kids
Make sure there’s parking close by, side gates are unlocked and the route to the door is clear. Apartment owners may need to book a lift or loading bay through building management.
Keep pets in another room or at a friend’s place for the day. An open doorway is an invitation for a dog to bolt. Children should stay well away from tools, glass and exposed openings.
6. Plan for Security and Weather
Don’t remove the old door yourself. Leaving it in place until the installer is ready keeps the house secure and weatherproof.
Ask whether the job will be finished in one visit and, if not, how the opening will be secured overnight. Perth’s winter storms and strong summer winds can make handling large glass panels unsafe, so be prepared for the installer to reschedule if conditions turn.
7. Inspect the Door Before the Installer Leaves
Don’t sign off until you’ve tried the door yourself. Check that:
-
It opens, closes and slides without dragging
-
The lock engages without forcing
-
Gaps around the door are even
-
Seals sit flat and the glass has no chips
-
Debris has been cleared, and you have the keys and warranty paperwork
Small adjustments are quick while the installer and tools are still onsite.
Why an Honest Assessment Matters
Not every tired door needs replacing. Worn rollers, a dropped panel or a sticking lock can often be repaired for far less. For the kind of door replacement Perth homes need most often, from aluminium sliding doors to security screens, Easy Door Solutions checks whether a repair will do before quoting a new door, with no call-out fee for the visit.
Frequently Asked Questions
How should I prepare my home for door installation?
Clear both sides of the doorway, protect nearby floors, make sure installers have parking and a clear path, and keep pets and children away from the work area. Confirm the door, hardware and frame details with your installer beforehand.
How long does it take to install a new door?
A straightforward like-for-like replacement is often finished within a day. Large sliding doors, frame repairs or changes to the opening take longer, and made-to-measure doors can need several weeks for manufacturing before installation.
How much does door replacement cost in Perth?
As a rough guide, a basic internal door costs around $250 to $500 installed, while an aluminium front door or standard aluminium sliding patio door typically runs $1,500 to $3,500. Frame work, hardware and access can push the price higher.
Can a new door be fitted into the existing frame?
Often, yes, if the frame is square, solid and free of rot or corrosion. Sliding doors are usually supplied with a new frame as a complete system. A damaged or distorted frame should be replaced so the new door seals and locks properly.
Should I repair or replace my door?
Repair is usually the better option when the problem is rollers, locks, hinges or alignment. Replacement makes more sense when the panel or frame is badly damaged, faults keep recurring, or you want better security or energy performance.
Do I need a permit to replace a door in Perth?
It depends on the work. A like-for-like replacement in the same opening is the simplest case, while enlarging an opening, altering a structural wall, or working on a heritage-listed or strata property may need approval. Check with your local council first.
Do I need to remove my old door before the installer arrives?
No. Removal is normally part of the installer’s job. Taking an external door off early leaves your home unsecured and exposed to the weather.
Final Thoughts
A smooth installation starts well before the installer arrives. Confirm the details in writing, clear the space, plan for pets and security, and test the door properly before signing off. Those small steps make the difference between a door that works perfectly and one that needs a callback.
