It goes without saying that when a construction site in Muskoka’s rocky terrain requires blasting, it’s important to call in the experts. Blasting is a highly specialized process that utilizes essential training and experience to ensure crew safety and to produce the desired result. At Josh McDermott & Sons, we prepare your site for blasting, bring in trusted explosives professionals, and clean up after the blast is completed.

Where your new construction project requires the removal of existing structures, our demolition professionals are here to help. We’ll dismantle and remove all or part of the building structures, including underground infrastructure, so that you can start your building project with a blank slate. 

Our crew takes the time to separate reusable or recyclable materials from demolished structures, as well as to properly dispose of hazardous substances and materials not suitable for recycling. And with heavy machinery and our fleet of vehicles, we’ll bring your demolition site to the desired state safely, quickly, and efficiently, so that you can move on to the next stage of your project right away.

Excavation & Site Prep

Top-quality site prep is the vital first step in every new build. When properly executed, site prep not only ensures a stable foundation for your building and safety for those involved in its construction, it protects against costly problems for the life of the structure.

Site prep is the preparation of a piece of land for construction. Depending on the property, it can involve everything from tree removal and basement excavation to demolition and blasting. Essentially, site prep is doing whatever necessary to make the property the ideal “blank slate” to begin construction. 

Site prep is a job that comes with surprises. Existing structures, trees, and Muskoka’s uniquely rocky terrain can present unforeseen obstacles that may delay your project. At Josh McDermott & Sons, we offer the highest quality site preparation services, informed by decades of experience. Our job isn’t done until your development site is in the ideal condition to begin construction. Contact us today for more information or to get a quote for your site prep project.

Sewer & Septic Services

Whether you’re looking to connect to municipal sewer services, replace or refurbish an existing field bed and septic system, or install a new system altogether, Josh McDermott & Sons has the expertise to get the job done right. Although invisible at the final stage of your construction project, these vital elements are absolutely crucial to the functionality of your home or business structure, and mistakes can be very costly. While Muskoka’s rugged terrain and unique water table mean that septic systems have to be carefully designed to avoid problems down the road, proper design and expert installation and refurbishment will ensure a smoothly running system for years to come.
