Do you build on footings or a slab?
For the majority of our sheds, our preferred method of construction is to dig foundations and pour concrete footings. The framework is then constructed from the ground up. The cost of digging the holes and providing the concrete for foundations has already been included in the erection cost and will not be a separate extra charge (unless otherwise specified).
Building on existing concrete slabs may not be appropriate in some situations. If the existing slab is cracked, too thin (where columns are to be located), is larger in area than the proposed building, uneven and not "square", then this can cause significant problems when trying to build a level, square, watertight shed. In these instances our recommendation is to replace the existing slab.
