5 Good Reasons to Hire a Residential Insulation Specialist

July 18, 2018

If you’re looking to either hire insulation professionals or make it a DIY project, there’s a good chance that your project is a sizeable one. Even if you feel it rests on the smaller side, there are plenty of factors and options worth weighing before you make your final decision. Having the proper protection, equipment and insulation is only half the battle. There’s also knowing the right insulation to use in each environment, having the correct knowledge and ability to install it, and air sealing any air leakage prior to adding insulation – depending on the type of insulation and where it is being applied.

Here’s a quick overview of why choosing a professional will make your project easier, and possibly save you time and money.

1. We Put Our History to Work for You

In 1980, Great Northern Insulation consisted of two people who knew they could offer more to their customers than other insulation companies. Nearly 40 years later, we have expanded to six locations across Ontario to serve even more people with the great expectations that have built up over the years. We haven’t gotten there by chance – it’s been through the dedication of making sure our customers have the best possible experiences with the products, the people and the process. It all starts with our customer satisfaction guarantee.

2. We Install Every Type of Insulation – And Beyond

Anyone can install insulation. But at GNI, we believe there’s more to insulating than simply adding insulation. When installing residential insulation, we have specific criteria for choosing the right product. Whether it’s the attic, basement, or exterior walls, the insulation product must block air movement, inhibit moisture accumulation, and provide maximum R-Value. In the attic and roof, we recommend spray foam as the ideal insulation material, with other options like batt insulation and loose-fill products. DIY spray foam products can be a hassle for the untrained applicator, leading to wasted product, messy cleanups, and a loss of time – all of this can actually add up to being more money than if a professional was hired from the beginning.

3. We Get It Right the First Time

Great Northern Insulation does it right the first time. Our installation techniques always satisfy the building code and abide by local bi-laws. Our people maintain strict building standards regardless of project size, and we never take unnecessary installation short-cuts. Customers receive a product warranty on everything that’s installed, as well as a sound company guarantee on installations. When you work with us, you’re assured of project follow-up in the event that you have any questions or concerns. You can even read our reviews  to see this care in action.

4. We Put Being “Green” First

It’s not easy being green, and that’s why a lot of companies choose to offer products that are not as environmentally friendly as others. Not all “green” insulation products are created equal either. And while every manufacturer is eager to offer a "green" product option (and installation), consumers must be aware and informed. Here, it’s important to choose a professional contractor that’s reputable and reliable. With Great Northern Insulation, products like Walltite ECO™ insulation are widely recognized for their environmental certification – the only spray foam insulation with EcoLogo™ certification. “Green” is guaranteed. We also take part in the Net Zero Energy Council and know how to build to Passive House standards.

5. We Know Our Rebates

Today, valuable rebates and incentives can help offset the cost of home insulation upgrades. With rebates from energy providers like Union Gas and Enbridge Gas, there are various options when doing energy efficiency upgrades or retrofits. In some cases, residential property owners could qualify for many thousands of dollars in incentives. The work has to be performed by insulation experts like GNI in order to ensure quality work. GNI can help with the qualifying pre-requisites.

With Great Northern Insulation, you know you’re placing your home’s energy efficiency into the hands of the most experienced insulation team in the industry. We don’t compromise when it comes to quality - and we provide our customers with the very best experience, from the first call to discuss your home assessment, to the day of installation when the only thing our professional installers leave behind is the feeling of comfort. We have been in business for almost four decades, with certified installers who deliver 100% customer satisfaction on every project.

If you’re looking to hire a residential insulation specialist, Great Northern Insulation can assess your needs and recommend the best approach. We treat your home as a "system", which means that we address every component of energy efficiency - insulation, air moisture, air leakage, and ventilation.
