Protect your home’s integrity and enhance its comfort and energy performance with smart, cost-effective upgrades by Zavaros Insulation. With our accurate home energy audit, we help you uncover your home’s major problems that may be hard to notice otherwise.

Getting our professional home energy audit can help discover issues such as drafty windows, worn-out attic insulation, pest infestation, mouldy drywall, damaged driveways, or cracks in your basement’s floor or foundation walls. Such issues must be discovered and fixed quickly to keep your family safe and healthy, and your energy bills low. At Zavaros Insulation, we not only help you identify your home’s hidden problems but also provide home improvement services and upgrades to boost your home’s comfort and efficiency levels.

Effective Insulation Installations at Affordable Rates


The insulation is a critical part of a home. It has to fit snugly around areas of different sizes and obstacles to be able to create an impenetrable barrier against the outdoor weather. At Zavaros Insulation, we help homeowners take control of their indoor climate and the home’s efficiency with advanced residential insulation solutions, including spray foam insulation. Our cellulose insulation is fire treated and makes homes safer by providing 55% more fire resistance than fibreglass. Over the past 24 years, we have helped customers insulate their modern homes, newly constructed or remodelled spaces, and vintage or retro homes for very affordable prices.
