Which Are the Best Insulation Companies in Calgary Right Now?
When it comes to insulation services in Calgary, knowing which companies to trust can be daunting. After interviewing industry professionals, we've compiled a list of insulation companies to help you make an informed decision.
A note on transparency: Beyond Insulation is part of the Beyond Group of Companies, which publishes this website. We've included ourselves because we believe we belong on this list, but we'll let you be the judge of that.
1. Top Gun Insulation They come highly recommended for they're personalized service and commitment to quality. As a smaller company, they offer a more hands-on approach, allowing customers to build a trusting relationship with the installer. Clients appreciate their competitive pricing and consistent high-quality work, making them the go-to choice for many homeowners seeking insulation solutions.
2. Beyond Insulation We have been serving Calgary for over 20 years, and we've built our reputation on doing what we say we'll do. Our team is trained to a high standard, and we focus heavily on keeping good people. We believe the crew that shows up at your home matters as much as the product going into your walls.
3. Ideal Insulation With a solid reputation built over the years, Ideal Insulation is known for their efficient services and expert team. Many interviewees highlighted that Ideal has been a reliable name in the industry, with a well-established workforce that ensures quality installation. Their focus on treating employees well is reflected in their low turnover rates, which contributes to a knowledgeable and consistent service.
4. High Performance Insulation
Another favorite among professionals is High Performance Insulation. This family-owned and operated business stands out for its quality workmanship and personal touch. Clients value the owner's hands-on leadership and the team's dedication to doing the job right. This company is particularly recommended for those who prefer working with a local business that understands community needs.
One of our highly experienced sales team said, "it's always good to get at least three quotes, one from a local small contractor, owner operator type deal, one from a small family style business, and one from a larger more corporate style company so that you can make a very well informed decision."
How Do I Know If an Insulation Company Is Legit?
Here’s what to look for:
- WCB and liability insurance
- Manufacturer certifications (especially for spray foam)
- Google and HomeStars reviews
- Detailed, written quotes with scope and material specs
- In-home assessments not just online forms
We always give an honest breakdown of what our professional opinion is of what the best solution would be for our clients so that whether they choose us or not, they're making the decision that's best for them.
What Do Calgary Homeowners Say About These Companies?
We scoured reviews and spoke with real customers. Here’s what people are saying:
- Top Gun Insulation: "They treated our home like it was their own."
- Beyond Insulation: "Not the cheapest quote, but easily the most professional."
- Ideal Insulation: "Installers knew exactly what they were doing—no guesswork."
- High Performance: "The owner was on-site and explained everything."
We had a customer choose us out of 4 quotes because the highest quote was $15,000 for an attic upgrade and out of the other three, though we were the highest of the three, had the best reviews.
What Types of Insulation Services Do These Companies Offer?
Most of these companies offer:
- Attic top-ups
- Spray foam insulation
- Blown-in cellulose or fibreglass
- Soundproofing
- New build & retrofit services
Beyond Insulation, for example, specialises in complex attic retrofits where air sealing and performance matter most. Attic insulation is often underestimated, yet it’s one of the most cost-effective upgrades a Calgary homeowner can make.
We've even told clients that they don't actually need the work done yet when other contractors have quoted them 10x what it should be if it actually needed to be done.
Spray Foam vs Blown-In vs Batt—Which Do These Companies Recommend?
It depends on your home:
- Spray Foam: High R-value, air seal, great for rim joists and cathedral ceilings
- Blown-In Cellulose/Fibreglass: Ideal for attic top-ups, cost-effective
- Batt Insulation: Common in walls, best paired with air sealing
Beyond Insulation often recommends a hybrid approach in older homes where both air sealing and R-value are needed. One of our lead installers explained, "It's not just about the number of inches—it's how well it stops airflow."
Who Offers the Best Warranties and Workmanship Guarantees?
- Top Gun: Offers a standard 1-year workmanship warranty
- Beyond Insulation: We provide a 3-year workmanship warranty and lifetime product coverage from manufacturers
- Ideal and High Performance: Varies by service but generally 1-2 years
Always ask: is your quote backed by warranty in writing? It matters.
Can These Insulation Companies Help Me Save on Energy Bills?
Yes—if installed correctly. The best insulation contractors will:
- Seal air leaks before insulating
- Use thermal imaging to find gaps
- Advise on rebates (like Alberta’s Home Efficiency Program)
One of our energy audit partners shared, "It’s not unusual for a home to cut heating costs by 25% after a proper attic retrofit."
How Fast Can I Book an Estimate or Get the Work Done?
Timelines vary by season. Here’s what to expect:
- Estimates: Usually within 3-5 business days
- Installations: 1-3 weeks out in winter, up to 6 weeks in peak summer
We recommend booking your assessment before spring rush hits. We had one customer delay until July and ended up waiting 2 months—lesson learned.
Are These Insulation Contractors Covered by Insurance and WCB?
All four companies listed carry WCB and $2M+ in liability insurance. But don’t assume—ask for proof. A reputable contractor will send it over without hesitation.
We've had clients tell us other contractors refused to share insurance paperwork. That’s a red flag.
Who Are the Owners or Experts Behind These Calgary Insulation Companies?
- Top Gun: A hands-on owner who manages the crew directly
- Beyond Insulation: Our leadership team has over 50 years of combined experience and a passion for doing the job right, not fast
- Ideal: Known for consistent training and a culture of quality
- High Performance: Owner-operated, strong community reputation
These are real people, not just logos. When you meet them, you’ll get a sense of who’s right for your project.
Still Not Sure Who to Hire? Here’s Our Honest Recommendation
