How to install a cavity sliding unit

Sliding doors are a versatile way to make better use of valuable space in your home. They’re great for smaller areas like walk-in robes, laundries, toilets and bathrooms.

Installing a cavity sliding door is quite a big job, but really straightforward. A timber and steel frame cavity sliding door kit from Masters makes it a whole lot simpler.

Installed into the cavity formed in a normal wall, each kit comes complete with frame, tracks and all the necessary fixings and jambs.  

With the right tools, preparation and advice from the team at Masters, you could be opening up more living space in no time.

Measure up    

It sounds obvious, but you need to make sure that you have enough space to fit the door. Your cavity opening has to be just over twice the width as the door you’re installing and you have to have room for the whole door to slide completely in.

Preparation

Take out the existing doorframe by removing the molding and slipping a reciprocating saw with a metal-cutting blade into the gap.

Cut any nails holding the frame in place and then just tip the whole doorframe out.

For stud walls, start by carefully removing the plasterboard followed by the studs and lintel with your saw.

Cut yourself enough headroom for the new frame.

For brick walls, check for possible obstructions and give the cavity floor a good clean out with a vacuum.

Framing

Once you're ready to start installing, saw the door header and track assembly to length, and fit using the supplied brackets and fasteners.

Now line up the structure and reinforce it with jambs of either thin metal or wooden packing. Make sure that the door header is plumb before you fasten it to the floor.

Position another pair of jambs in the middle of the framing. The instructions that come with your kit will tell you exactly where you need to install them.

Install the bumper doorstopper on the stud at the back of the frame.

Fitting the door

Attach the sliders to the top of the door about 95mm in from each edge and slide the wheeled trolleys into the track. Hook the hangers onto the trolleys.

Keep adjusting until the door hangs perfectly plumb and then install any latches, pulls or locks.
Finishing Up

Secure the replacement plasterboard with adhesive and screws. Apply jointing cement, tape it and wipe off excess cement. Once dry, sand it and apply the next layer of the cement the same way.
            
Now it’s time to trim the door by cutting and installing architrave or cover strips all the way around the frame.

Tips

  • You’ll need a cavity in the wall that’s just over double the width of the door you’re installing.

 

  • Always check for electrical wiring or plumbing. It may sound obvious, but it’s an easy mistake that could be dangerous and costly.

 

  • Be sure that the rough opening is plumb and the header is level. Otherwise your door is going to give you trouble all its life.

 

  • If the wall is load bearing you’ll probably have to replace the existing lintel with a longer one. Consider getting a professional in for that.

 

  • It’s a good idea to paint or stain the door before you install it.
