Josh McDermott & Sons Construction is a third-generation Muskoka business. Our roots go way back to 1937, when Josh McDermott, who was born and raised in Muskoka, started the company by stepping in wherever he found an opportunity. This included general maintenance, hauling, digging, and road building throughout Muskoka. Through hard work and determination, Josh’s business grew, and he was soon able to purchase bigger and stronger equipment and hire a crew.
