How to install your new staircase

Whilst Pear Stairs highly recommend that a qualified joiner fits your staircase, skilled DIY enthusiasts may attempt the task themselves. This is a guideline to fitting the staircase:

Basic Procedure To Fit Your Staircase.

1.

Check critical dimensions before proceeding:

 

a) Check well size is as per plan.
b) Finished floor to finished floor dimension.
c) Overall width of the staircase.

2.

Always fit your staircase from top to bottom.

3.

Cut the top newel to fit onto trimmer.

 

Firstly cut out top newel to fit onto trimmer. Do not fix newel at this stage.

 

For details of a Trimmer see "Measuring Your Staircase" in Help & Resources 

  install our staircases - elevation on newel and trimmer
   
 

Put riser temporarily into position.

Scribe line the thickness of riser to determine the depth of the sawcut.

  install our staircases - cut out to suit depth of trimmer
   
 

After marking your line, allowing for the thickness of riser, make saw cuts with a cross cut saw for easy removal with mallet and chisel.

Using a mallet and a chisel, remove slithers of cut wood to leave a recess to fit onto trimmer.

4.

Cut the bottom newel to the correct length.

 

Cut bottom newel to correct length.

If the floor is not level it is possible that the newel may differ in length.

Newels are always delivered extra long to allow for this.

Fit and glue bottom newel onto the string.

The dowel holes are drilled slightly off centre to pull the newel and string tightly together.

Taper the dowel slightly for easy insertion.

Once the piece is pulled up tight, cut off the excess dowel and back.

Fit bottom riser.

 

With the bottom newel fitted slot the riser into position and mark bottom riser in line with bottom of newels.

Take riser out and cut to correct length.

 You can now fit the riser into position by screwing into the riser and then the newel, also use glue.

On the string side, the riser needs to be kept in place with a wedge as shown below.

Please ensure that plenty of glue is applied to both edges and inside face of the wedge.

Tap wedge firmly into place.

Remove excess glue with a chisel.

 6.

 Fit the glue blocks.

 

 

 View looking underneath the staircase, showing glue blocks.

The majority of these blocks will already be glued on your staircase.

Once the bottom rise is fitted the blocks will need to be fitted.

We recommend about 3 or 4 blocks per tread.

Use plenty of glue, and when positioning the blocks, move back and forth to remove all the air.

Fit the top newel.
