Attic Insulation in Bloor West
Your attic is where up to 40% of your home's heat escapes. Spray foam insulation air-seals and insulates in one step—stopping ice dams, cutting energy bills, and keeping every floor comfortable year-round.
Signs Your Bloor West Attic Needs Insulation
Most Bloor West homes—especially detached houses in Bloor West Village, older properties in Baby Point, and semi-detached homes in Swansea built before 2010—have inadequate attic insulation. Here's how to tell.
Ice Dams in Winter
Icicles hanging from your eaves mean heat is escaping through the attic and melting rooftop snow. This freeze-thaw cycle damages shingles, gutters, and causes interior leaks.
Uneven Temperatures
Second floor is sweltering in summer and freezing in winter while the main floor is fine? That's your attic failing to contain conditioned air.
High Energy Bills
If your heating costs keep climbing despite a functioning furnace, air leakage through the attic is likely the culprit. It's the #1 source of heat loss in most homes.
Moisture or Mould
Condensation in the attic, damp rafters, or visible mould growth indicate warm humid air from your home is reaching the cold attic space. Spray foam stops this.
Drafts & Cold Spots
Feel cold air near light fixtures, attic hatches, or recessed lights on the top floor? These are air leakage points that only spray foam can properly seal.
Old or Settled Insulation
Fibreglass batts sag and compress over time, losing up to 50% of R-value. Blown-in cellulose settles. If your insulation is 15+ years old, it's likely underperforming.
Open-Cell vs Closed-Cell for Bloor West Attics
The right foam depends on your attic type, budget, and goals. Here's a side-by-side comparison.
| Feature | Open-Cell (½ lb) | Closed-Cell (2 lb) |
|---|---|---|
| R-Value per Inch | R-3.7 | R-6.5 |
| Air Sealing | Excellent | Excellent |
| Vapour Barrier | No — vapour permeable | Yes — at 2" thickness |
| Moisture Resistance | Absorbs water | Waterproof |
| Structural Strength | Flexible, no racking strength | Adds wall/roof rigidity |
| Sound Dampening | Superior — absorbs sound | Good |
| Cost per Sq Ft | $1.50 – $3.50 | $3.00 – $5.00 |
| Best For | Vented attic floors, cathedral ceilings where vapour permeability is needed | Unvented roof assemblies, flat roofs, cathedral ceilings, basements |

Where We Apply Attic Spray Foam
Every attic is different. We insulate all common attic configurations found in Bloor West homes.
Attic Floor (Ceiling Joists)
Standard application for vented attics. Spray foam between and over joists creates a continuous air barrier on the ceiling plane.
Roof Deck (Underside of Sheathing)
Creates an unvented, conditioned attic space. Ideal when HVAC equipment or ductwork is in the attic.
Cathedral Ceilings
Between rafters for vaulted rooms. Closed-cell is typically required to achieve code R-value in the limited rafter depth.
Knee Walls
Common in older homes throughout Bloor West Village and Baby Point. Seals the transition between conditioned and unconditioned space.
Attic Hatches & Pull-Down Stairs
Major air leakage points that most insulation methods miss. We seal and insulate these access points completely.
Rim Joists
Where the attic floor meets exterior walls. Often overlooked, rim joists are a significant source of air leakage and heat loss.

Real feedback from attic insulation projects across the Bloor West area.
"Our post-war bungalow in Bloor West Village had major ice dam problems—water damage in the upstairs bedrooms every February. GTA Foaming sprayed open-cell foam and the issue is completely solved. Two winters with zero ice buildup. Best investment we made."
"The second floor of our Baby Point Tudor was unbearable in summer—over 30°C even with AC running. They sprayed closed-cell on the roof deck and now it's comfortable all year. Gas bill dropped about 40% this winter too. Excellent work."
"Got three quotes for our Swansea semi. GTA Foaming was the most detailed—actually measured the attic instead of estimating from outside. Professional crew, respectful of our neighbourhood, finished in one day. Highly recommend to anyone on Bloor West."

Attic Insulation FAQ — Bloor West
Common questions about attic spray foam insulation for Bloor West homes.
Ontario Building Code recommends R-50 to R-60 for attics in Climate Zone 6, which includes all of Bloor West. With spray foam, you can achieve this with approximately 8–10 inches of open-cell or 7–8 inches of closed-cell foam.
Yes. Ice dams are common on post-war bungalows and older homes throughout Bloor West Village, Baby Point, and Swansea. Spray foam creates an air-tight seal that prevents heat from escaping into the attic, eliminating the freeze-thaw cycle that causes ice dams and protects your home from water damage.
For most Bloor West attics, open-cell is cost-effective and provides excellent air sealing and R-value. Closed-cell is recommended for cathedral ceilings common in Tudor-style homes, areas with limited attic depth, or situations requiring a built-in vapour barrier and maximum R-value per inch.
Attic spray foam in Bloor West ranges from $1.50 to $3.50 per square foot for open-cell, and $3.00 to $5.00 for closed-cell, depending on thickness and accessibility. Most residential attic projects cost between $3,000 and $8,000. Older homes may require additional prep work.
Most Bloor West attic spray foam installations are completed in one day. A typical 1,200–1,500 sq ft attic takes 4–6 hours including prep, application, and cleanup. Parking on residential streets is coordinated in advance.
Not always. If existing insulation is dry and in good condition, spray foam can sometimes be applied over it. However, many older homes in Bloor West have settled or compressed insulation, moisture issues, or vermiculite (which may contain asbestos)—removal is recommended in these cases before spraying.
Yes. Once fully cured (24 hours), spray foam is completely inert and safe. During installation, we ventilate the work area and recommend occupants and pets stay out of the immediate area. You can return to normal use of your home the next day.
Spray foam applied to the attic floor (vented attic design) does not affect your roof warranty. Spraying the underside of the roof deck (unvented assembly) may impact some shingle warranties. We'll discuss this during your site assessment and help you make an informed decision for your Bloor West property.
