Customer Comments . . .

Darrell assisted Homes by Avi with fine tuning some of our building envelope details. What I really appreciated was Darrell’s understanding of an assembly as a system. He avoided the “magic-bullet” answers and helped us come to solutions which suit our construction practices and company culture.

- MICHAEL JACOBSON Homes by Avi Calgary & Edmonton

“When our home builder discovered mould in our 4 year old home they could not elaborate on the extent of the problem nor could they give us a good explanation as to the locations or severity of the situation. When Darrell with Qualistat was brought in he did a complete analysis and gave us a good understanding of the situation, remediation to the problems, and a sense of security back in our home." “A True Professional”
