Description of the work to be performed

A couple decides to replace their old wooden staircase with a more contemporary model. This custom made staircase is leaned against a wall 8 m long and a height of 2.50 m. The owners wish that two people can cross without disturbing themselves. The chosen model is therefore wider than the old one and the hopper * a little wider. In the wooden floor, part of the work is to rebuild the joists at the periphery of the hopper. The manufacturer assures only the installation of the staircase, they call upon a carpenter to carry out these works as well as the removal and finishing (painting), an additional cost of 1 200 € TTC.

Our comments

Choose the right form
Not all forms of stairs are suitable for any configuration. It all depends on the existing hopper and available space. If the hopper is long and narrow, a straight staircase will be preferred. If the floor space is insufficient, we will turn to a quarter-turn staircase. And for a square-shaped available surface, one will choose a two-quarter turn staircase. In any case, it is better to call on a specialist (carpenter, manufacturer of stairs ...) to find the best configuration.

(1) A staircase to standards
A ramp is not only decorative, but above all a safety function. The height must meet specific standards: at least 90 cm along the rise and 100 cm on the bearings. Sign of quality: a ramp must not move. Make sure your posts and fixings are strong and sturdy.

(2) Attention to the head
The escape must never be less than 190 cm at any point on the stairs. An essential precaution to avoid bumping your head.

(3) Easy climb
For the same height, the more steps, the slower the slope. Be aware however that the number of steps a person can climb without fatigue is set at 20. Beyond that, it is necessary to create a landing that will allow rest. Note also: for optimum comfort, the walking height must be between 16 and 20 cm.

(4) A well integrated staircase
When space is lacking, the ideal is to opt for a quarter-turn model. This configuration is recommended for connecting a ground floor to a floor. Indeed, it facilitates the passage of bulky objects (furniture, etc.).

(5) A staircase mounted quickly
A staircase arises quickly. Count 1 day for the simplest versions, 2 for the most sophisticated.

(6) Reduced VAT
For a main house built for more than two years, the replacement of a staircase allows to benefit from a reduced rate VAT, provided to call a professional.

VOCABULARY TO KNOW

Arrival recession: total length of the staircase projected on the ground and which therefore determines its size.
