01Linear footage and coverage
Drainage is priced by the length actually installed. A proposal covering one wall and one covering the full active perimeter are different purchases, and the footage should appear in writing rather than a description like 'perimeter drainage'.
02Interior or exterior access
Interior work means concrete cutting, dust control and finish restoration. Exterior work means excavation, soil handling, depth, and whatever sits in the way — decks, walks, plantings, utilities or a close property line.
03Foundation material and condition
Poured concrete, block and stone walls fail differently and are repaired differently. Stone and rubble foundations frequently need repointing or localised rebuilding that a poured wall does not.
04Whether the structure is moving
A stable crack that leaks is a focused repair. A bowed, displaced or actively moving wall is a structural project with reinforcement, excavation or underpinning attached, and may need an engineer to specify it.
05The sump and its discharge
Cutting a new pit through the slab, adding a dedicated electrical circuit and routing a discharge to a legitimate outlet are each substantial. On many properties the discharge route costs more than the pump.
06Backup power and alarms
Battery or water-powered backup, and a high-water alarm, are separate items. In Vermont they matter more than usual, because the storms producing the most groundwater are the ones most likely to cut power.
07Demolition and restoration
What finishes come out, what goes back and who pays for it. This is the single most common reason two proposals differ at the bottom line while appearing to describe the same work.
08Electrical, permits and engineering
Who performs the electrical work, whether permits are pulled, and whether an engineer's involvement is included or billed separately.
09Season and site access
Frozen ground makes exterior excavation and grading impractical or expensive, which is why autumn is the practical deadline for that portion of a project in this climate.
10Rural constraints
Private well and septic locations, long discharge runs, no municipal storm system and restoration across lawn or field all affect the scope on a rural property.
