Calculating the installation costs of a trellis

Under Installation, you can find all the necessary information. If you need professional help, try asking a trusted facility manager, installation company, mason, painter, façade specialist, or metal worker. Of course, a gardening landscape contractor or company are also options. For large projects, it may be useful to let the contractor or company take care of buying the necessary materials. We provide a list below of what prices to expect.

No insulation / ETICS: Please bear in mind that the installation costs will be approximately double the order value (total price of the trellis system = order value × 2). This applies if the order value is at least around € 300, the greenery is to be installed on lower or easily accessible sections of the façade, there are no slopes or similar obstacles, etc..

Walls with insulation or ETICS: In this case, the material costs – i.e. the order value with FassadenGrün – are already high, whilst the installation costs are, proportionally speaking, slightly lower. Please bear in mind that the installation costs here are significantly lower than the order value (total price of the trellis system = order value × 1.75). This applies if the order value is at least around € 5.000, the greenery is to be installed on lower or easily accessible sections of the façade, there are no slopes or similar obstacles, etc..

Under more difficult conditions, as with the following examples, estimate 1.5-2.5 times the value of the trellis system material for the assembly (total costs = order value x 2.5-3.5): if the terrain is sloping, when deadlines have to be met, in compromised weather like frost, of if special equipment (usuallly for high trellis systems) is required-- long ladders, mobile scaffolding, or cherry pickers. Even with very small projects, the assembly costs are often 2 times the material costs. 

The costs for planting are to be considered separately. They vary according to the chosen climbing plants, the extent of soil improvement needed, the preparation of the planting area (if needed) and the costs of plant care.

Sometimes tenders ask for prices per square metre. In such cases, it must be clear whether the price is for one square metre of trellis (net area) or one square metre of green space (gross area). Of course, climbing plants always grow beyond a climbing aid and thus form a ‘gross field’ on the wall. But how big should the difference between the ‘gross green field’ and the ‘net climbing aid’ be? You can find more information on this under ‘Partial greening’.
