If you want to make some improvements to your building's exterior, you should rent scaffolding. Here are two reasons why this equipment could be so useful.
It could prevent errors and accidents that would disrupt the building work
One reason why scaffolding can be helpful during exterior renovation projects is that it can allow the people involved to avoid having accidents that could disrupt their building work. For example, whilst a ladder can easily get blown over on a windy day whilst someone is on it or standing beside it and leave this person so badly hurt that they cannot continue working, the same is not true of scaffolding, as this equipment is secured to the wall and is only at risk of collapsing during extremely severe weather conditions (when people would not be doing renovation work anyway).
It can also prevent errors that could delay the remainder of your renovations. For example, if you choose to use scaffolding when painting your building's exterior, you always have the option of putting your open paint tin anywhere on the scaffold's stable, spacious floor, instead of having to hold it by the handle in one hand whilst painting the wall with your second hand. This could reduce the likelihood of you spilling paint down the wall and onto the windows or the paving beneath you.
It could allow you to make more complicated improvements without changing the current schedule
Another reason why scaffolding could come in handy in your situation is that it might allow you to make more complicated improvements to your building's exterior (such as painting a mural on one of the walls) without having to extend the project's length. The reason for this is that when you do renovation work from a scaffold instead of a ladder, you can work far more quickly. This is mostly because you can keep all of your bulky tools and equipment on the scaffold floor by your feet, instead of having to descend and re-ascend whenever you need to use a new tool (as is the case when you're working whilst on a ladder).
Furthermore, you can access most or even all of a wall whilst standing on one scaffold platform, which means that you can easily progress from working on one area of the wall to the area beside it, without having to readjust the position of your access equipment, like you would need to when using a ladder. This can be an amazing timesaver that could help you to get more complicated work done without making schedule changes.
