Ontario's Trusted
Insulation Experts.
Over a decade of making Ontario homes and buildings more comfortable, more efficient, and better built.
Built on a Simple Idea
Earthwise Canada was founded on one belief — that insulation should be done right the first time, with clear communication and no shortcuts. We got into this industry because we kept seeing homeowners get vague quotes, poor installs, and no follow-up. We decided to do it differently.
We're a Canadian-owned insulation company based in Ontario. We work with homeowners, landlords, property managers, and commercial operators — always with the same approach: assess properly, recommend honestly, and install with care.
Over 3,500 projects later, that approach hasn't changed.
Our Values
Honesty first
We tell you what you actually need — not the most expensive option. If a simple top-up solves your problem, that's what we'll recommend.
Do it right
Every install is done properly, with the right materials, the right coverage, and the right verification. We document everything with before and after photos.
Respect your home
We protect every work area, show up on time, and clean up fully before we leave. Your space gets treated the way we'd want our own treated.
Respect your time
We show up when we say we will, finish on schedule, and keep you updated. Most installs are done in a single day so you're not waiting around.
Built for Ontario
We understand Ontario's climate, building codes, and housing stock. Our recommendations are designed for how this province actually works — cold winters, older homes, and all.
Quality materials
We use industry-leading insulation products that don't settle, resist moisture, and hold their R-value for years — not just until the next inspection.
The Standard We Hold Ourselves To
Earthwise was started after years of hearing the same complaints — contractors who quoted without looking, installs that didn't match what was promised, and homeowners left wondering if anything actually changed. We decided to build something different.
Our team brings hands-on expertise across every type of insulation work — attic upgrades, spray foam, removal, air sealing, and commercial installs. Every technician knows the materials, understands Ontario's building standards, and takes pride in the finish. This isn't a crew that shows up and guesses.
We're a small team and we plan to stay that way. Every job gets the same attention because every job has our name on it.

After our attic insulation service we could instantly feel a difference in our home's comfort. It would normally be a lot colder upstairs and it was actually really warm! The service team was very clean and very professional. 10/10!
Highly recommend Karan and the Earthwise team. Excellent professionalism, great communication, and timely service. My attic looked just like brand new after insulation removal. GREAT TEAM!!! GREAT WORK!!!! GREAT PRICE!!!
Great experience with Karan. He was honest, explained in simple language and straightforward. He showed up when he said he was going to and did a good job. We noticed a difference very quickly in our house heating. Definitely will recommend.
Great job! Very knowledgeable! They communicate what they are going to do — and do it! Provide pictures before and after. Clean, professional, punctual. Will use them again and have already recommended to friends and business associates!
