## What we are an authority on

- How Twin Cities soils behave under basement conditions (glacial till, Anoka Sand Plain, kettle-lake fill, late Wisconsin moraine). We cite the Minnesota Geological Survey for the underlying geology; our authority is the field-level translation, not the academic geology itself.
- Interior drain tile systems (engineering, installation, costs)
- Sump pump engineering (cast iron vs plastic, PSC vs shaded-pole, M53 vs M98, battery vs water-powered backup)
- Hydrostatic pressure and how it acts on basement walls
- Foundation crack diagnosis (shrinkage vs structural, horizontal vs stair-step)
- Regrading and surface water management
- Spring thaw flooding patterns in Minnesota
- Musty basement diagnosis (geosmin, MVOCs, the order to eliminate sources)
- What basement water damage typically looks like inside a homeowners insurance claim, from the contractor side (HO-3 form, endorsements, claim playbooks). Note: we are not licensed insurance professionals; for policy interpretation, the MN Department of Commerce and a licensed insurance agent are the authoritative sources.
- Commercial below-grade waterproofing
- Twin Cities city-by-city basement context (27 city pages)

## What we do not give advice on

- HVAC sizing or dehumidifier specifications (refer to a licensed HVAC contractor)
- Crawl space encapsulation (we do not offer this service yet)
- Legal or insurance interpretation (we are a contractor, not an attorney or licensed insurance professional)
- Foundation structural engineering (we refer to structural engineers when needed)
