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.

Do I need to seal before adding insulation?

Yes, and it is the part most often skipped. Warm moist air leaking from the house frosts the roof deck and wets the insulation. Blowing over unsealed pot lights and top plates buries the problem instead of fixing it.

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.

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.

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.

My bathroom fan seems to vent into the attic. Is that a problem?

Yes, and it needs correcting before insulating. It dumps warm wet air into the coldest part of the house, and burying it under fresh insulation hides a moisture source that will show up later as frost and staining.

Attic top-ups in Larkspur that hold their depth

The most common mistake in an Larkspur 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.

Cellulose against fibreglass in an Larkspur attic

Two products, different behaviour

Blown cellulose is denser, settles into gaps well and resists air movement through it better. Blown fibreglass is lighter, does not settle as much over time and is less prone to holding moisture.

How we choose

Either performs when installed to the right depth with the ceiling sealed underneath. We pick based on what is already up there and how the attic is built, and we tell you which we would use and why rather than defaulting to whichever is on the truck.

Larkspur drywall in context

About Larkspur

Larkspur was named after an ornamental wildflower plant that blooms in many colours.

Ventilation is not optional up there

Cold attic, by design

An Larkspur attic is meant to run close to outdoor temperature so the roof deck stays cold and snow does not melt and refreeze at the eaves.

The failure it prevents

Blocking soffit vents with insulation causes exactly the ice damming people add insulation to prevent. Air sealing the ceiling below and keeping the vents clear are two halves of the same job.

Storage in the attic and the insulation you lose

Boards over joists compress everything

Where a Larkspur homeowner has laid plywood across the joists for storage, the insulation beneath is squashed to joist depth. That strip performs at a fraction of the rest of the attic.

Options

Either the storage area is raised on a platform above the finished insulation depth, or it is accepted as a deliberately weaker zone kept as small as possible. What does not work is topping up around it and pretending the platform is not there.

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 Larkspur attic either blocks the venting or leaves a cold band above every exterior wall.

Pot lights, and which ones can be covered

Not all fixtures are equal

Older recessed fixtures in Larkspur ceilings need clearance and cannot be buried. Newer IC-rated fixtures are built to be in contact with insulation.

What we check

We identify what is installed before blowing. Where fixtures cannot be covered, they need boxing or replacing — and each one is also a significant air leak, so they are usually the first thing sealed regardless of type.

Topping up against removing and replacing

Usually a top-up is fine

Old fibreglass in an Larkspur 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.
