Customer Testimonials

Your pre-planning and forethought were obvious…Your workers were efficient and a pleasure to have on the project. Each carried out their work diligently, carefully and avoided impacts to ongoing operations in adjacent occupied spaces.
Steve Leonard, Construction Representatives & Consultants
“[Reliance] saved our project schedule. We ran into an unforeseen situation that could have cost us a considerable amount of time…[They] came in on short notice and scraped the whole space in a weekend. As a result, we were ready to roll on Monday morning, right on our original schedule.”
