How to Know When to Upgrade Your Home Insulation
Most homeowners don’t think about insulation until their heating bills spike or rooms start feeling uncomfortable. But Edmonton’s harsh winters make proper insulation crucial — and knowing when it’s time to upgrade can save you hundreds each year on energy costs.
1. Uneven Temperatures in Rooms
If some rooms feel freezing while others stay warm, that’s a red flag. Uneven temperatures usually mean air is escaping through poorly insulated walls, ceilings, or attics. A professional energy audit can pinpoint where the heat loss happens.
2. High Heating and Cooling Bills
A sudden increase in your Enmax or EPCOR bill—without a change in usage—often signals that warm air is leaking out and cold air is seeping in. Upgrading insulation can reduce energy bills by up to 30% in older homes.
3. Drafts and Cold Spots
If you feel cold air near windows, doors, or floors, your insulation may be inadequate. Air leaks and insufficient insulation allow outdoor air to enter, forcing your furnace to work harder.
4. Ice Dams or Frost in the Attic
During winter, check your roof for icicles or ice buildup along the edges. These form when heat escapes from the attic and melts snow, which then refreezes. Frost on attic beams is another telltale sign your insulation is insufficient or uneven.
5. Old or Compressed Insulation
Insulation materials like fiberglass or cellulose lose effectiveness over time—especially if they have become wet or compacted. If your home is more than 15–20 years old and hasn’t been re-insulated, it’s worth having a professional inspection.
6. Moisture, Mold, or Musty Odors
Condensation on windows, damp attic areas, or musty smells in basements often mean your insulation no longer provides an effective moisture barrier. Upgrading to spray foam or rigid foam can help seal out humidity.
7. Noise between Rooms or from Outside
Insulation doesn’t just retain heat inside; it also reduces noise. If you hear sounds from your neighbours, home traffic, or between floors, you can benefit from higher-density insulation materials.
When is the best time to upgrade home insulation?
In Edmonton, the ideal time to upgrade insulation is late spring through early fall, before temperatures drop below freezing. Installers can safely remove old materials, seal leaks, and apply new insulation without weather delays.
If your home feels drafty or you have noticed an increase in your heating bills, don’t wait for the perfect time to upgrade insulation. Modern insulation can be installed at any time of the year with the proper preparation by an experienced contractor.
What Makes a Great Insulation Company?
Before looking at good insulation companies, it would help to know how to distinguish a good contractor from a mediocre one.
Here are the key attributes to look for in a good insulation company:
Technical Expertise & Certification
- For spray foam, the correct mixture, application technique, curing, and safety protocols are important.
- Certified installers or recognized credentials assure you that the crew is well-trained.
- Knowledge of building science, moisture control, ventilation, and local building codes is crucial.
Range of Services
- A full-service insulation contractor offers attic insulation (blown, batts, loose fill), spray foam (open and closed cell), insulation removal, vapour barriers, air sealing, and remediation of moisture or mould.
- They can assess ventilation, insulation upgrades, and rebates/incentive programs.
Reputation & Reviews
- Look for past project photos, client testimonials, and references.
- Local reputation matters as word of mouth is strong in Edmonton’s communities.
Transparent Quotes & Diagnostics
- A reliable company will inspect your attic or wall cavities, identify weak spots, suggest optimal R-values, and provide a clear, itemized quote.
- Be cautious of quotes given over the phone without visiting the home.
Warranty, Insurance & Guarantees
- They should carry liability insurance and offer warranties on materials or workmanship.
- They must clean the work site, protect your home and its contents during work, and conduct a proper cleanup.
Local Experience & Understanding Climate
- Edmonton’s winters can be harsh. Local contractors are knowledgeable about condensation, freeze/thaw cycles, ice dams, attic venting, and radiant heat loss and can provide the best solutions to your home insulation needs.
With those benchmarks in mind, here are several of the top insulation companies in Edmonton you should consider.
Popular Residential Insulation Services in Edmonton
When you choose one of our insulation partners, you are guaranteed that the technicians doing the work qualified for the job. Whether you want cellulose, fibreglass, or spray foam insulation for your residential property, our partners can install them.
Each home requires a different insulation approach depending on its age, structure, and budget. The main insulation services offered in Edmonton include:
Attic Insulation
The attic is the most cost-effective place to upgrade insulation. Most houses in Edmonton need R-60 or higher to prevent heat loss. Blown-in cellulose or fiberglass is the most common method.
Spray Foam Insulation
Spray foam provides superior air sealing and moisture control. It is good for basements, crawl spaces, rim joists, and walls. Closed-cell foam has higher R-values but is more expensive.
Blown-In Insulation
This method is ideal for enhancing existing insulation in attics. It’s fast, affordable, and reduces heating costs quickly. It is installed using special equipment, and is ideal for irregular shaped spaces, unfinished attic flooring, and hard-to-reach places.
Batt Insulation
Walled batt insulation or fibreglass batt insulation is commonly used for basic walls in homes and commercial properties.
Basement & Crawl Space Insulation
Spray foam or rigid foam board insulation prevents condensation and mould in below-grade spaces.
