Help & FAQs

Over the years, we have heard almost every conceivable question regarding staircases and stair parts. To help make the subject as simple as possible, here is a list of some of the most common: 

Q. Is there a restriction on the gap you can have between spindles?

Yes. The maximum gap between spindles, and in fact any part of the staircase is 100mm. This applies anywhere where children under 5 years old will be, to ensure they cannot fit through the gap.

Q. Is there a limit to the size of the stairs?

Yes. And these depend on where the staircase is going to be (see below). The size of the staircase is governed by the rise and go of the step, for which there are regulatory requirements as follows:

Private stair:
For a typical house the required parameters for this type of stair are maximum rise (Step height) of 220mm, minimum go (Step depth) of 220mm and a maximum pitch (Angle of elevation) of 42 degrees.

Institutional or Assembly Stair:
For a communal building (where substantial numbers of people live or visit) the required parameters are maximum rise of 150mm, minimum go of 280mm. 

Other Stairs (Semi Public):
For stairs not covered in the categories above the required parameters are maximum rise of 190mm, minimum go of 250mm and a maximum pitch of 38 degrees.

Q. Can Clive Durose build our stairs?

Clive Durose is not a staircase manufacturer but can supply your stair parts and put you in touch with a stair manufacturer in your area. Please visit our 'Looking for a full staircase' page.

Q. Are spindles strength tested?

All of our spindles have been strength tested at design stage to ensure they meet the requirements of BS6180. Please note however that whilst all of our spindles are suitable for use in private dwellings, if you are putting spindles in commercial or multiple occupancy properties, you need to ensure you use those that are tested to this standard.

If you have any technical questions about any of our products, get in touch and we will be happy to answer them for you.
