Let John McLellan Contracting Give Your Exterior a Chic Makeover


Whether you have a modern home or an aging residence, McLellan Contracting can enhance its exterior. With a decade of experience, we have proven our expertise in managing complex exterior renovation projects. We specialize in installing and replacing decks, soffit, fascia, eavestrough, and cladding.

A Range of World-Class Products

Our aluminum soffit and fascia are manufactured in state-of-the-art facilities and meet stringent quality standards. We offer decks made from premium-grade pressure-treated wood or composite decking materials. We choose materials that last much longer than many traditional siding options and offer superior resistance to the elements.


Our quality products may cost a bit more up front than cheaper alternatives on the market, but with proper care and maintenance, they outperform and outlast them. Additionally, they are more reliable and require less frequent repairs. If you're planning multiple projects on the same property, you may be eligible for volume discounts.

Unlike many exterior renovation contractors who focus solely on profit, we prioritize building strong customer relationships. We understand the importance of effective communication and keep our customers informed about their project's progress, sharing updates at regular intervals. We stand behind our work and offer comprehensive workmanship warranties.



Choosing an uninsured exterior renovation contractor may seem cost-effective, but it can lead to significant liabilities if a worker gets injured on your property. At McLellan Contracting, we are safety trained and carry workers' compensation. If any of our team members sustain injuries while working on your property, we have coverage, protecting you from unpleasant surprises.


Since 1995, McLellan Contracting has been a trusted name in exterior renovations. We’ve kept the same phone number since 1997, standing behind our work and ensuring our clients receive the highest quality service. We emphasize the importance of WSIB and insurance to protect our clients and our team.
