Our Process

We worked hard to create a repeatable process where our customer can expect consistency that you can predict


Talk to Kari and answer some questions about your project, and schedule to have a team member assess your property.


We gather information by inspecting, documenting, and sketching to create a honest recommendation for you. After the inspection, you will be contacted within 24 hours to scheduled consultation to review the diagnoses and the recommendation.


The consultation is design for customer education, review, and recommendation. We sit down and get to know you; talking about budgets, concerns, and preferences for your project. Your Sales Associate, as an advisor, works with you to find a solution that fits your situation. Once your preferences are finalize, a contract is created digitally and signed.


Once you are on our board, your project gets inspected by our Project Verification Manager. They review Work Orders to ensure accuracy in materials ordered. After verification, Kari contacts about your estimated delivery of materials and an install date. Then construction occurs from tear off to installation of new materials.


Clean-up is taken very seriously. We have the crew do a clean-up at the end of each day with a final clean-up at the end of the project. After the installation and clean-up, the Quality Control Inspection is conducted. We walk through the project ensuring all debris is removed and installation meets our requirements.
