What to include in your estimate request

Compare findings before products

Ask for a written assessment with photographs and the proposed source of the problem. Separate drainage, plumbing, ventilation and structural concerns.
Request reasons for each proposed barrier, pump, insulation or repair rather than treating a package name as a diagnosis.

Keep structural work explicit

For foundation or seismic work, ask whether engineering, permits and inspections are needed and who is responsible.
Specify access, excavation, disposal, utility protection, restoration, monitoring and warranty limits in the scope.

Oregon credential and permit starting points

Check contractor credentials and discuss structural and permit requirements with the relevant local authority. A license record is not an engineering diagnosis or approval of a retrofit design.

Common questions

Is encapsulation the same as foundation repair?

No. Ask which problem each proposed measure addresses and whether structural assessment is separate.

Should seismic work get its own scope?

Yes. Keep its assessment, design, approvals and installation responsibilities separate from general moisture or insulation work.
