Calculating working height
Choosing the right working height prevents you from standing too low or unnecessarily high with a scaffold. Here is how to work it out quickly and easily.
Working height versus facade height
The working height of a scaffold is not the same as the height of the facade or roof you are working on. The working height is the platform height plus the reach of an average adult: roughly 2 metres with an outstretched arm. So to determine the right working height, you do not measure the facade height itself, but the point where you actually need to be able to work (for example the top of a gutter or the highest point of a window frame), and add about 1 metre of comfortable working space on top of that.
Worked example
- Height of the highest working point (e.g. top of the gutter): 6 metres
- Reach with an outstretched arm: roughly 2 metres
- Required working height: roughly 6 – 2 = 4 metres platform height, in other words a scaffold with 6 metres working height
Rather not calculate? Use the configurator
The configurator on the homepage works this out automatically for you based on the type of job you enter. Still in doubt? Then choose a size larger: working too low is unsafe and awkward, and hiring a slightly higher working height usually costs little extra.
Frequently asked questions
How quickly can I hire a scaffold?
In many cases we can deliver the same or the next working day. Order before 15:00 and delivery the next working day is usually possible. For urgent requests you can let us know by phone or via WhatsApp.
What does it cost to hire a scaffold?
The hire price depends on the model and the working height. For an RS51, reckon on around 12,50 euros per metre per week, with delivery costs and deposit as separate items. See the exact prices in the configurator above.
Is delivery included in the hire price?
No, delivery is calculated separately based on distance and region. The delivery price is clearly shown in advance, with no hidden costs.
Do I need to be home for delivery?
Yes, we ask that someone is present to discuss the placement and to take receipt of the scaffold. This prevents misunderstandings about the desired location.
Do you also assemble the scaffold?
For most orders the scaffold is assembled safely and completely by our fitters in accordance with EN1004. Hire without assembly is also possible in some cases; ask about the options.
How high can a mobile scaffold be assembled?
Our RS51 and RS52 are available up to a working height of 14,2 metres. For greater heights, additional wind load and anchoring requirements apply, which we go through with you in advance.
What is the difference between working height and platform height?
The platform height is the height of the working surface itself. The working height is the platform height plus roughly 2 metres of reach for an average adult. See our knowledge base page for a detailed explanation.
Which scaffold do I need for exterior painting?
For most homes an RS51 or RS52 is suitable, depending on the desired stability and width. Based on your facade height, our configurator gives suitable advice straight away.
Can I also collect the scaffold myself?
Yes, self-collection is possible at our depot and saves delivery costs. Do keep in mind that you need a suitable trailer or van, as the parts are relatively long.
Why do I have to pay a deposit?
The deposit covers any damage or loss of parts during the hire period. On correct and complete return, you get the full deposit back.
How much is the deposit?
The deposit varies per model and hire period and is clearly communicated in advance. See the section about the deposit on this page for the exact amounts per product.
When do I get my deposit back?
After the scaffold has been checked at collection or return, the deposit is usually refunded to your account within a few working days.
Is a mobile scaffold from the DIY store not cheaper?
A DIY-store scaffold may seem cheaper, but often lacks the stability, certification and completeness of a professional Altrex scaffold. See the comparison section above for the details.
Is the scaffold safe for use by a private individual?
Yes, provided it is assembled and used according to the instructions. During assembly our fitters run through a safety check with you, and we always provide instructions on maximum load and wind conditions.
What if it is very windy during my job?
At wind force 6 or higher we advise against working on the scaffold, and it should be anchored or taken down if necessary. We give concrete advice about this during assembly.
Can the scaffold stand on any surface?
The scaffold needs a flat, load-bearing surface. On soft ground, grass or uneven paving we use base plates to distribute the weight properly.
Does the scaffold fit through a narrow gate or passage?
The RS51 is specially designed for narrow passages from around 70 cm. If you are unsure whether the scaffold fits, measure the narrowest passage and consult our team.
Can I hire the scaffold for several weeks?
Yes, hire periods can be flexibly extended. The longer you hire, the more favourable the price per week often works out.
What happens if my job is finished earlier?
You can have it collected earlier than planned. Depending on the remaining hire period and the moment of notification, we settle this where possible.
Do you also deliver to business parks?
Yes, we deliver both to private homes and to business parks, HOA properties and commercial construction. Contact us for bespoke solutions on larger projects.
Can a painting company also hire from you?
Certainly, we regularly work with painting companies and contractors who want to hire equipment rather than buy and maintain it themselves.
Is the MiTower suitable for indoor work?
The MiTower is compact, light and quick to assemble, which makes it suitable for indoor work such as painting ceilings or installation work.
What is the difference between RS51 and RS52?
The RS52 is wider and offers more stability and working space, while the RS51 is more compact and fits better in narrow spaces. See the comparison table above.
Do I need my own tools to assemble it?
No, with guided assembly by our fitters you do not need your own tools. For self-collection and assembly we recommend following the supplied instructions.
Can I book online or do I have to call?
You can book directly online via the configurator on this page. If you prefer personal advice, we are also happy to help you by phone or via WhatsApp.
What if the scaffold gets damaged during the hire period?
Report damage to us as soon as possible. Normal wear and tear falls outside the deposit scheme, but for significant damage part of the deposit may be withheld.
Can I use the same scaffold for several jobs?
Yes, many customers move the scaffold themselves during the hire period to another spot on the same property, as long as this is done safely and according to instructions.
Do you also deliver to an apartment complex?
Yes, we have experience with delivery at apartments and HOA properties, including coordination about communal set-up spots and accessibility.
How many people can work on the scaffold at the same time?
This depends on the model and the maximum load stated in the product specifications. We always provide this at assembly and in the documentation.
Can I have solar panels installed using your scaffold?
Yes, many installers hire a scaffold from us for safe access to the roof when installing or maintaining solar panels.
Do you also offer advice on which scaffold fits best?
Yes, use the configurator for automatic advice based on height and application, or contact us via WhatsApp for personal advice.
Should I measure the height to the ridge or to the gutter?
Measure to the point where you actually need to work. For gutter work that is the gutter itself, not the ridge of the roof.
What if I am between two working heights?
Then always choose the higher of the two. Working too low is unsafe; on a higher platform you can always still work bent over or crouched.
Does the working height vary per person?
The reach of 2 metres is an average. If you are clearly taller or shorter than average, take that into account when choosing the working height.
