Stira manufacture some of the safest and strongest loft ladder systems available so they feel like a set of stairs underfoot as opposed to a ladder.
We can also install your Stira loft ladder system in a completely new location/room if required. This involves creating a new opening. This is often the only option if your current opening is in a tight spot and can’t be adjusted or extended as required. We can also install into lath and plaster ceilings. Both these services incur extra cost which our surveyor assessor will confirm with you should they be applicable.
Please note: Should extra works need to be carried out such as taking up flooring, removing existing insulation, having to box out an area to make it work, or attending to a customers personal request, these extra works which incur extra cost.
