Below is a run through on how to construct a staircase. But first, a few quick tips;

Everything is pre-cut and dry fitted in our Workshop

When deciding how to fit a Newel posts, remember that our newels have been dry fitted in our workshop. In other words, DO NOT amend or trim anything unless specified in the Steps below. This is the number 1 rule when you are trying to figure out how to fit a newel post. If you feel that you have no choice please contact us, it could be that you have something in the wrong place and just need a fresh pair of eyes.  

Dry Fit First

We would always suggest that you dry fit the newel post first of all. Once you have done this and are happy with the fit, only then would we suggest adding the bit of glue to fix everything in place.  

Make sure that everything is square

Your newel post is the anchor for the rest of your staircase and if that is out of square then the rest of the flight will follow suit. Make sure that the newel post is 90° to the tread.  

No gaps allowed

Make sure that there are no gaps between the post and tenon shoulder, the dowels or bolts should pull this into place.  

Once up, leave it

Once the staircase is up and glued, leave it for a while. Allow the glue to fully set before you walk up and down it, this may not sound like much but it can be the difference between your staircase having that one annoying squeak or being forever squeak-free!  
Next, have a quick watch of this video. This goes through, action by action, exactly what is needed to fit your Newel Post.
Next, let’s get into the guide-proper:  


Any newel posts that should be sitting on the floor will already be cut to floor level, the only instance where this would not be the case would be if you have already called us when designing the flight to let us know that a newel needs to go beyond floor level. In this case we will have sent the newel post a little longer than is needed so that it may be amended on site as necessary.


Posts will have been dry fitted in our workshop so providing you have the newel post in the right position it should slide straight on. Every newel should be labelled in a manner that will correspond to the CAD drawing, should there be any confusion please feel free to give us a call on 01782 832555. Dry fit the post and when you are happy that everything is in place add glue to the mortice slot and tread housing.


Either the dowels or bolts (dependant upon the staircase ordered) are now to be used to secure the newel onto the string. Dowel holes will be offset slightly so as to pull the post tight upon fitting it. Bolt holes should be correct and will naturally pull everything into place nice and tight. Once in place the bolts should be covered using plugs, the same goes for dowels should they be made of a different material.


Additional treads and winders now need to be fitted, once in place slide and fix the risers. Should you have a bullnose step this will need to be glued and screwed into the newel post and the string trenching.


This stage is very important, and if done correctly your staircase should be forever squeak free! Dry fit each riser around the newel posts, trimming where required. Be aware longer risers are for the kite winders. Once you are happy the riser fits, run a small bead of glue (we recommend PU woodweld or similar) within the newel housing and along the back of the tread where the riser will be screwed. Beware not to over glue this joint, especially if the flight is not being carpeted as the glue can be difficult to remove from the face of your staircase - it’s best to run the bead of glue towards the under edge of the stair.


You are now ready to screw the riser to the tread, if your treads and risers are MDF we recommend 40mm screws, on timber 30mm should be ample to fix a 10mm riser. Use 3-4 screws in the pre-drilled holes, be careful not to overtighten or let the screws spin. If screwing into a hardwood tread you will need to drill a pilot hole approximately 2-3mm in diameter. You can also use 1-2 screws to secure the riser into the newel post housing. The next step is to glue the angle blocks in place with generous amounts of glue, it is very important that these are fixed properly and the glue is allowed to set before use.
