How much insulation should my attic have?

It is settled depth and even coverage that decide performance, not the product name. We set depth markers before blowing so the result is measurable, and check the corners rather than just the area near the hatch.

Should I block the vents to stop drafts?

No. The attic is meant to run close to outdoor temperature so the roof deck stays cold. Blocking soffit vents causes exactly the ice damming people add insulation to prevent.

Why is the area above my exterior walls always cold?

Geometry. The roof meets the wall at the lowest point in the attic, so there is least room exactly where it is needed most. Baffles hold insulation back from the soffit vents while letting depth carry over the wall plate.

How do I know I got the depth I paid for?

We leave depth markers through the attic so the installed depth can be read off by anyone afterwards. Depth is easy to claim and hard to check once the hatch is closed, which is exactly why we mark it.

Do you insulate over an addition or a vaulted ceiling?

Those need looking at specifically rather than quoting an average depth. Shallow attics, cathedral sections and knee walls are usually the coldest rooms in an Windermere house and the parts a general top-up misses.

Will insulating my attic stop the ice at my eaves?

Often it helps a great deal, because ice damming is usually escaping heat melting snow that then refreezes over the cold overhang. Air sealing plus even coverage to the eaves lowers the deck temperature, which is the actual cause.

Attic Insulation Windermere Edmonton | Attic Top-Up

Attic top-ups in Windermere that hold their depth

Attics in Windermere lose depth over time — insulation settles, someone crawls through it for a wiring job, and the corners near the eaves are usually thin to begin with. A top-up is only worth doing if the baffles are clear and the ceiling below is sealed, so that is what we check before quoting.

Baffles kept clear so the soffit vents still breathe
Existing insulation levelled before the top-up
Depth markers left in place so the result is verifiable
Air sealing at pot lights, top plates and the attic hatch
Attic hatch insulated and weatherstripped
Blown-in loose-fill to the depth your permit specifies

Adding to what is already there

You rarely start empty

Most Windermere attics already have something, whether old batts, older loose fill, or both in layers.

When to top up and when not

If the existing material is dry, even and uncontaminated, adding over it is usually the best value. If it is wet, compacted, rodent-affected or hiding unsealed penetrations, removing it first is worth the cost, and we say which one we found.

Windermere drywall in context

About Windermere

Windermere likely comes from the words "winder", which means "to take one's breath away", and "mere", which refers to the boundary of an area or a significant landmark.

What we see in Windermere

In Windermere the drywall work is first-year settling, basement dev for first owners, Level 5 over builder-grade. We confirm what your home actually needs on site, in writing, before anything starts.

Keeping the eaves clear in an Windermere attic

Ventilation and insulation are not opposites

An attic needs air moving from the soffits up to the ridge. Blowing loose-fill right into the eaves blocks that path, and a blocked attic gets damp regardless of how much insulation is in it.

Baffles

Baffles hold the insulation back so the soffit vents stay open. In older Windermere homes they are often missing entirely, which is why the corners look thin — someone deliberately kept the insulation back, or it was never installed to the edge.

Bathroom and kitchen fans venting into the attic

Found more often than you would think

In older Windermere homes a bathroom fan is frequently ducted into the attic space rather than through the roof or soffit. It dumps warm wet air straight into the coldest part of the house.

Why it matters before insulating

Burying that under fresh loose-fill hides a moisture source that will show up as frost and staining. If we find one we tell you, because it needs correcting first — insulation on top of it makes it harder to reach and harder to diagnose.

Topping up against removing and replacing

Usually a top-up is fine

Old fibreglass in an Windermere attic that is dry and undisturbed can be levelled and topped up. It still insulates, and removing it is a large cost for a small gain.

When it has to come out

Insulation that is wet, contaminated, or full of rodent activity gets removed rather than buried, because topping over it seals the problem in. We will tell you which of the two you have after looking, not before.

Insulating a Windermere attic with knob-and-tube or old wiring

Stop and check first

Some older Windermere homes still carry active knob-and-tube wiring in the attic. Burying it in insulation is not something we do — it needs an electrician to assess and usually to replace before the attic is filled.

Why we raise it

It is the kind of thing found halfway through a job, and it is far cheaper to find at the quote. If we see it, we tell you and we stop until it is dealt with.

Ice damming and what the attic has to do with it

A heat problem, not a gutter problem

Ice at the eaves on an Windermere roof usually means heat is escaping into the attic, melting snow on the upper roof, and that meltwater refreezing over the cold overhang.

Where the fix actually is

More heat tape rarely solves it. Sealing the air leaks and getting even insulation coverage right out to the eaves is what lowers the deck temperature. That is why we look at the attic when someone calls about ice, not at the roofline.
