About us

Two carpenters who put their names on every job.

Escarpment Contracting Co. is Zack Posteraro and John Gadomski: an owner-led exterior contracting company based in Mono, Ontario, building decks, siding and eavestrough across the hills from Caledon to Collingwood.

Our story

Built in the Headwaters, for the Headwaters.

We are a local carpentry business from the Caledon and Mono area. We started with siding, decks and eavestrough because those three trades decide how a home looks from the street and how it stands up to the weather coming off the escarpment.

Working owner-led keeps the standard where we want it. Zack and John each lead a crew, so the owner who quotes your project is the owner running the build: the same name answering questions, flagging surprises and standing behind the result. Our clients keep hiring us back for the next project, and that repeat work is the business model.

You will also find us at the Orangeville Lions Home and Garden Show, and Zack holds the exterior contractor seat in the BNI Georgian Triangle chapter in Collingwood.

Our foundation

What we hold ourselves to.

Craft over speed

Even reveals, clean mitres, hidden fasteners where the material allows. The details neighbours notice without knowing why.

Straight answers

Honest trade-offs between materials, problems shown to you when we find them, and a written quote before work starts.

Respect for your home

Landscaping protected, the site cleaned every day, and a completion walkaround before we call anything finished.

What clients say

The reviews tell the story better than we can.

Had Zack & John from Escarpment Contracting come perform a siding project at one of my projects in downtown Toronto. I can attest to their hard work and dedication to their craft, they bring an educational approach to the products they use, which helped me in choosing the best option. Their customer service is top-notch; they answered every concern I had, and if there was anything I needed clarity on it was responded to promptly. Keep up the good work lads!

John and Zack are a pleasure to deal with. We've had the good fortune of working with them on a number of occasions over the past few years. Always prompt, always professional, their work is immaculate and of the highest caliber. It often draws compliments from neighbours and visitors without prompting. We've referred them without reservation to many friends and neighbours.
