Working Out Your Fixing Costs

Every builder approaches construction projects differently. As we go through each job we break out fixings and will aim to get the cost component as close as possible.

While it may not be possible to precisely estimate every single plug, screw or bolt, we ensure transparency by including a line item for “miscellaneous fixings” and allocating a reasonable sum based on the scale of the project.

It is important to note that we will always outline and separately account for more expensive fixings such as SS bolts, ensuring they are not included in the miscellaneous fixings category. In each paragraph, we will use bullet points to clearly highlight multiple costings for specific fixings.

All in all we do our best to outlay the bulk amount of fixings for each part of the job so those costs are well covered and included in every project.

By itemising a significant portion of the fixings required in construction projects, we aim to provide comprehensive cost estimations. While it may not be feasible to precisely estimate every single plug screw or bolt, we ensure transparency by including a separate line item for miscellaneous fixings and allocating an appropriate budget based on the project’s scale. 

Additionally, we make a point to outline and account for more expensive fixings such as SS bolts separately; these costs can really kill profit margins.
