Investing in quality attic insulation is one of the best decisions you can make for your home. Proper attic insulation doesn’t just improve comfort—it delivers lasting benefits that enhance your home’s efficiency, durability, and value.

Our Attic Insulation Services
Professional attic insulation services for homeowners in Edmonton, Red Deer, Calgary, and nearby communities.
New Attic Insulation Installation
Upgrade your home with high-quality cellulose or WallBAR insulation for better comfort and efficiency. We fully cover gaps, seal problem areas, and install insulation the right way so you get even temperatures, fewer drafts, and long-term energy savings.
Attic Insulation Upgrades
Older or thin attic insulation leads to cold rooms and high heating bills. We bring your attic up to modern energy standards by adding more insulation, fixing weak spots, and improving coverage. This helps reduce monthly energy costs and makes your home feel warmer and more consistent.
Attic Insulation Removal
Old or damaged insulation can cause drafts, odours, and poor indoor air quality. Our team safely removes outdated insulation and cleans the space so your attic is ready for a fresh, efficient upgrade. This gives you a cleaner, healthier attic and better performance once new insulation is installed.
Frost & Condensation Solutions
Attic frost and condensation often come from heat loss or poor ventilation. We find the cause and provide solutions like air sealing, insulation upgrades, and better airflow. Fixing these issues helps prevent moisture damage, mold growth, and winter “attic rain.”
Attic Insulation Options for Every Home and Budget
Every home is different. That’s why we offer several types of attic insulation, each with its own benefits for energy efficiency, cost savings, and long-term performance. Our experienced insulation installers can help you choose what’s best for your space.
Blown-In Insulation
Blown-in cellulose insulation is a popular option for upgrading attic spaces. Ideal for covering uneven areas and improving your home’s energy efficiency quickly.
Spray Foam Insulation
Great for sealing gaps and preventing air leaks. Spray foam insulation provides high R-value and moisture resistance.
Loose Fill Insulation
A cost-effective way to top up existing insulation. Especially useful in attics with difficult access or wall insulation needs.
Fiberglass Insulation
A long-lasting, affordable option that’s safe, fire-resistant, and great for both attics and walls.
Foam Insulation Panels
Used in specific areas like attic hatches or small wall sections to increase thermal resistance.

How Attic Insulation Protects Your Home
Get clear, simple information to help you understand your attic, spot problems, and choose the right insulation solution.
Attic insulation works by creating a thick, even layer of protection that slows heat from escaping your home in winter and stops hot air from entering in summer. When your attic has the right insulation level, your furnace and AC don’t have to work as hard, and the temperature in each room stays more stable.
A good insulation job includes full coverage, proper depth, and sealed gaps so warm air can’t leak into the attic. This helps reduce drafts, cold spots, high energy bills, and moisture problems like frost or condensation.
Most homes use cellulose insulation, which is safe, effective, and great at reducing heat loss. It fills gaps well and gives consistent coverage across your attic floor. We also use WallBAR insulation in some homes, which offers excellent air sealing and long-term performance.
Each attic is different, so we choose the right insulation type based on your home’s age, attic layout, moisture levels, and energy-efficiency goals.
You may need more attic insulation if you notice:
- Cold rooms in winter
- Hot upstairs bedrooms in summer
- Drafts or uneven temperatures
- High heating or cooling bills
- Frost, moisture, or “attic rain”
- Thin or patchy insulation when you look inside the attic
If your home has never had an insulation upgrade, it’s very likely under-insulated by today’s energy standards.
Adding or upgrading attic insulation gives your home:
- Lower monthly energy bills
- Warmer rooms in winter
- Cooler rooms in summer
- Fewer drafts and cold spots
- Better protection against frost and condensation
- A more comfortable home all year
It’s one of the most cost-effective upgrades you can make to improve comfort and efficiency.
Homes with poor attic insulation often run into issues like:
- Heat loss: warm air moving into the attic
- Cold rooms: inconsistent temperatures between floors
- Moisture and frost: caused by air leaks and thin insulation
- High energy bills: furnace or AC running too often
- Ice dams: snow melting and refreezing on the roof edge
Fixing these problems usually requires a mix of better insulation, air sealing, and improved ventilation.
Attic insulation costs depend on a few simple things:
- The size of your attic
- The current insulation level
- Whether old insulation needs removal
- If air sealing or ventilation improvements are needed
- The insulation type used
We provide clear, upfront pricing and help you choose an option that fits your home and budget.
Our process is clean, simple, and professional:
- Inspection: We check insulation depth, air leaks, moisture, and ventilation.
- Plan: You get a clear recommendation based on your home’s needs.
- Prep: We protect your home, set up equipment, and make sure the job is safe.
- Install: We add new insulation or upgrade what you have for full, even coverage.
- Final check: We confirm everything meets the right energy-efficiency level.
You get a cleaner, warmer, more efficient home—without the hassle.

The staff are friendly, professional and eager to help. Would not hesitate to recommend them for any job required. Top notch!!Posted on RobertTrustindex verifies that the original source of the review is Google. Just had Cosy top off my attic to R60 with Weathershield insulation. The guys were on time and did a fantastic job. Before starting the job they went through the process with me and then proceeded with laying out plastic to protect my floors and walls. Once they stretched out the hose to pump the insulation through and sprayed the WeatherShield in the attic. After removing the blower hose, plastic and tools, the vacuumed their work area. in addition to energy savings we will receive, we have noticed a quieter upstairs from the sound damping effect from the extra insulation. Highly recommend this company. Thank you, Clarence SPosted on C SurfinTrustindex verifies that the original source of the review is Google. Had Cosy out to blow in insulation. Company was great to deal with from booking the appointment through completion of service. Workers were careful to put down plastic and clean up after themselves. Price was also very reasonable.
