Before getting an installer over, here are a number of things to think about for you attic stair installation.


Will an Attic Stair Installation fit in your home?

Homes can vary widely in size, shape and layout. So it’s always a good idea to check a few things out before ordering your attic stair installation. Take a quick look both above and below the ceiling to ensure you have a clear area to install the system.


Here’s a few tips to consider before installing your new Attic Stair:

1) Floor space: 

Attic ladders often need around 1.7m2 of free floor space to fold down onto. We often advise they are installed in hallways of towards the centre of rooms where furniture will not get in the way.

2) Roof space height:

It’s good to aim to install the stair towards the centre of the home. This is so you can walk up into the roof space at its tallest point rather than bumping your head on the sloping roof in the attic.

3) Ceiling hanging objects:

Have a look at the ceiling where you hope to install the staircase. Are there any vents, smoke alarms or light fittings in the area that could get in the way? Moving a light fitting, for example, may require an electrician so it’s best to pick an area of the ceiling that would allow a 1200x600mm free space.

4) Ceiling height:

How tall is your ceiling? This is important to know when choosing your attic stair. All stairs can be trimmed to suit however they need to be a good length to start. If you have a standard 2.4m to 2.8m ceiling we would advise selecting our 2.8m attic stair. If you have a ceiling of 3m we advise our taller 3.05m or 3.25m attic stair. If your ceiling is taller than this we can also offer a tall 3.6m specialist unit.

Measure the floor to the ceiling height and choose a stair that is appropriately sized.

5) Attic height:

Can you move in your attic? An attic that you can stand up in is ideal, however, you can still get good storage areas from attics as low as 1 metre. Aim to fit your stair system in the clearest and tallest part of the attic. This will make boxes easier to move around and place into the attic area.

6) Truss roofs:

Some roofs will have supports running from the rafters to the ceiling joists. Where these supports meet the joists is a structurally important area. It’s best not to locate the stairs where any beam or trusses intersect as this could weaken the roof.

If you have beams coming from the roof to the joists we advise looking for another area to fit the stairs. You may have to install the stairs in a different direction so these beams are not cut. Can the stair fit between joists rather than across them?

7) Pipes, cables, ducts and tanks

Attics can be busy places when it comes to cables, pipes, old header tanks and cylinders and ducting. We advise getting up into the roof and clear the insulation from the area you hope to fit the stair. Have a look for any pipes and cables that may block access for the new manhole. Consider relocating cables if needed, or seek another area to fit the stair.

8) Have a plan B location for your attic stair installation

Sometimes our installers come up against unforeseen issues with the primary chosen installation location. It’s a good idea to also consider a second favoured location if there are pipes or cables that could complicate installation.
