Who you deal with
One project lead and the crew
One project lead takes your job from the site visit to the final walkthrough. That is the person who answers the phone, and the person who walks the finished job with you.
The photos on this page show the crew on real Korvex jobs: framing decks, setting fence posts, compacting stone and laying slabs.

Why the base comes first
What an Ottawa spring shows
Most outdoor problems in Ottawa show up in spring: a patio that heaved, a fence that leans, steps that rock. Almost always the cause is underneath: a thin base, soil that holds water, a yard that slopes toward the house.
That part is also the easiest to skip, because nobody sees it once the job is done. So we photograph it. Many projects on this site show the base, the fabric and the drainage before they were covered.
