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.

Can you just blow on top of what is already there?

Usually yes, if the existing insulation is dry, undisturbed and not contaminated. If it is wet or shows rodent activity it comes out first, because topping over that seals the problem in rather than fixing it.

Will you block my soffit vents?

No. Baffles hold the insulation back at the eaves so air can still move from the soffits to the ridge. A blocked attic gets damp no matter how much insulation is in it.

How much insulation should my Sherwood Park attic have?

The depth comes from what the code asks for on your permit, not from us. What we can tell you is the depth you have now, whether it is even, and whether the eaves and hatch are dealt with — those three often matter more than the last few inches.

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.

Why does my Sherwood Park attic frost up in winter?

Almost always warm moist air leaking up from the house through pot lights, top plates or the hatch, then condensing on cold sheathing. More insulation on its own does not fix it — the leaks have to be sealed first.

Attic Insulation Sherwood Park | Attic Top-Up

Attic top-ups in Sherwood Park that hold their depth

The most common mistake in an Sherwood Park attic is blowing insulation over an unsealed ceiling. Warm moist air keeps rising through pot lights, top plates and the hatch, and it carries moisture into cold insulation where it condenses. We air-seal the penetrations first, then insulate.

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

Depth, and how to check we delivered it

Verifiable rather than assumed

Blown insulation settles, and depth is easy to claim and hard to check once the hatch is closed. We leave depth markers through the Sherwood Park attic so the installed depth can be read off later by anyone.

Even coverage

Depth is also an average — a deep drift in the middle and thin corners is not the same as an even blanket. Coverage to the edges is what actually reduces heat loss.

Sherwood Park drywall in context

About Sherwood Park

A high share of Sherwood Park homes date from the Poly-B era, so repipe patching and texture matching after a plumbing replacement is common here.

What we see in Sherwood Park

In Sherwood Park the drywall work is both plaster and stipple repair and new-build basement development. We confirm what your home actually needs on site, in writing, before anything starts.

Insulating a Sherwood Park attic with knob-and-tube or old wiring

Stop and check first

Some older Sherwood Park 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.

Depth is the whole number

What you are buying

Attic performance is almost entirely a function of settled depth and even coverage. Two attics with the same product can perform very differently.

How we handle it

Depth markers are set before blowing so the result is measurable rather than asserted, and the Sherwood Park attic is checked at the corners rather than only where the hatch is. An attic that is deep in the middle and thin at the perimeter is the usual finding.

Sealing the ceiling below first

The order that matters

Warm moist air leaking from the house into a cold Sherwood Park attic is what frosts the underside of the roof deck and wets the insulation.

Where it leaks

The hatch, pot lights, bath fans, plumbing stacks and the top plates of interior walls. Blowing more insulation over unsealed penetrations buries the problem instead of fixing it, so sealing comes first.

Keeping the eaves clear in an Sherwood Park 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 Sherwood Park 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.

The eaves are where it goes thin

Geometry works against you

The roof meets the wall at the lowest point in the attic, so there is least room for insulation exactly where the wall below needs it most.

What it needs

Baffles that hold the insulation back from the soffit vents while still letting depth carry out over the wall plate. Skipping them in an Sherwood Park attic either blocks the venting or leaves a cold band above every exterior wall.
