Assisted Review

An assisted review is collected by a contractor on behalf of the homeowner after their work is completed. The homeowner must confirm the text of the review and may make any changes she or he deems appropriate. The homeowner then assigns the contractor a review score out of 10. Assisted reviews receive the same scrutiny as other reviews and must follow our review guidelines.

ECHO SYSTEM DBTI has built many great ECHO System finished basements over the years. All of them have depressurization versus exhaust flow rate values that exceed our minimum requirements. To my knowledge there has never been a call back. This takes quality, honest workmanship, something I know you can count on from Bill Walls every time. Douglas S.
