These are the repairs themselves. If you are still working out which one you need, the basement problems pages start from the symptom instead and route you here.
Water Out, or Wall Held Up
Almost everything on this list falls into one of two jobs, and confusing them is the single most expensive mistake available to a homeowner.
Waterproofing manages water. Interior waterproofing intercepts it at the footing and pumps it away; exterior waterproofing excavates and stops it reaching the wall at all. Both are drainage work, and neither adds a pound of structural capacity.
Structural repair holds a wall up. Basement wall repair — carbon fiber, steel bracing, or in severe cases rebuilding — resists soil pressure. It does not make anything dry.
A wall that is both wet and moving needs both, in that order, and any quote that solves one while ignoring the other is only half a job.
Where Most Jobs Land
Basement waterproofing is the overview page and explains how the interior and exterior approaches differ, when each is justified, and why the expensive one is sold far more often than it is needed.
Sump pump installation and sump pump repair cover the mechanical end. A pump is the cheapest part of a drainage system and the part most likely to be the actual problem — worth checking before anything else gets quoted.
Foundation crack repair covers injection for the cracks that only leak, and explains which cracks should not be injected because they are still moving.
The Two Specialist Jobs
Egress window installation is code work as much as repair — a below-grade bedroom needs a compliant opening, and this is the page to read before finishing a basement.
Crawl space encapsulation applies to the minority of local houses with a crawl space rather than a full basement, often an addition on an older property.
What It Costs
Ranges for all of the above, with the reasons they vary, are on the costs page. Inspections are free and carry no obligation, and if what you have needs no work, that is what you will be told.
