How ProPerks Works

  • Step 1

    Fill out the ProPerks Membership signup form. Once you're verified as a trades professional, you'll get a welcome email.

  • Step 2

    Work one-on-one with us on an ongoing basis to make selections and purchases. Local contractors get complimentary cabinet renderings, onsite measurement services, and more you won't find at other distributors.

  • Step 3

    We process your discounted orders within 24–48 hours, with discounts that continue going forward. No membership fees. The more you purchase quarterly and yearly, the greater your discounts.

Dedicated Pro-Account Manager

Get as much or as little help as you need. Tired of hearing your account manager is "not available" or that whoever picks up can't help? At Great Lakes, anyone on the team can assist with product knowledge, inventory, install guides, lead times, specs, and more. That's the difference with a family-owned business — chances are, you'll be working one-on-one with an owner.

Showroom & Product Selection Help

We help our pros' residential clients with product selections and kitchen cabinet renderings in our Grayslake showroom. We don't offer installation or remodeling to homeowners — we sell products and refer them to our trade partners, which is what we're all about. We can meet virtually with anyone, and we work with commercial procurement departments on product selection and design details too.
